applications on sd card cannot be found - Nook Color General

booting sd card with latest stable 7 release.
Just turned on my nook in android mode and all my applications on sd card are not accessible.
I have rebooted numerous times and used recovery and still no apps. When I open settings, I can see the apps on the sd card tab but cannot move them back to phone or clear them.
Don't know what happen? Any solutions to get my sd card applications working again? My nook will boot up fine with sd card but lost all the sd card apps.
The sd card storage is strange. I have a 16bg and now says .89mb used and 1.0gb free. it used to say 13.? free.
Any Thoughts?
appreciate the help

similar problem
I just started a new thread a few minutes ago describing a similar problem. I lost the ability to browse apps after installing a couple of them from App Brain. I know the apps are there, but I have no way to browse and launch them.
Wish I could say I have an answer for you...

I'm not sure of the exact cause of your problem. But i had a similar issue recently on CM9. Changing to a different launcher fixed the basic problem, and then when i switched back to my preferred launcher, the sd card apps were still visible. Hopefully this will work for you too. I ended up switching to a different launcher permanently.

This can happen if you swap what cm7 views as the sdcard, from removable to emmc. Check your settings within Cyanogen/Applications. If use internal storage is checked, then the system is looking for your SD apps on the wrong SD.
Or you could have a corrupted card. I hope it is the first option. Hope this helps.
Looking at your memory fluctuations, I bet the above is right. That is the available memory amount for a nook out of the box without the customizable repartition zips. Which are awesome. At the moment, you have all your memory allocated to data, which is totally unnecessary, and a waste of perfectly usable forage. If you need directions to the directions (assuming this solves your problem, post and ask.

SD doesn't always detect and issues installing apps

Guys, I've been searching for the last couple of weeks for solutions to what I believe is a unique problem with N1, so here I am ...
Basic details of NI:
Mod: Cyanogen 6.0.0
Kernel: 2.6.34.5
Baseband: 5.08
Build: FRF91
Issue number 1: Intermittent detection of SDcard.
A few weeks ago the N1 was not detecting my SDcard. I searched the web and tried a number of solutions. What has worked for me is to shut down, reseat the SDcard and hope for the best. Sometimes this would work after a couple of attempts other times I'd try this over days...
So I decide to buy a new card. Kingston 16gb SDHC. I format this for FAT32 copy my files across and pop it in. It gets detected, but once again intermittently, though it is detected after a shutdown and reseat more often than the previous card.
Now here is the uniqueness of my issue which I haven't been able to find in other places.
Even is the card is detected by the system and loads all the applications that are installed on it, if I go to 'manage applications' and select an application the 'total', 'application' and 'data' fields under storage show "computing..." and this doesn't change no mater how long I leave it. This is also the case for 'cache'.
Also, if I go to 'sd card and phone storage' it show the total space and available space no problems, but if I try to unmount it stalls then crashes out of settings.
I have no trouble reading either card on my Windows 7 machine.
Does anyone have any ideas on this particular issue?
Issue number 2 is that I can't update my apps ... it always gets stuck on 'installing ...'. I suspect however that if I sort out issue 1, issue 2 will also be solved.
Any help is much appreciated, as I'm rather at my wits end...
Ok, so an update on this. I've done a bit more reading, and discovered that my problem isn't so unique after all. Have tried a number of things, but nothing has worked perfectly for me yet.
I've wiped the card, reformated and the phone now detects it.
When I copy across all the files again the card stops being detected again.
So then I delete everything but the .android_secure folder and it still doesn't detect.
Does anyone know what app could be causing this?
I've seen some success by formatting the SD with a specific PC based program. Formatting from the phone gives mixed results.
Unfortunately, I can't remember the name, so you'll have to search...
If I remember, I'll post back...
Sent from my Nexus One using XDA App
Try SD Formatter.
http://www.sdcard.org/consumers/formatter_3/
So after tinkering around with this issue a little bit, I ended up deleting the .android_secure folder.
After this everything seemed to work again. I could install apps and the card was being detected just fine.
Now, a couple of weeks later, I am having the same issues and it is again driving me nuts.
Does anyone have an idea of what the app is that is causing this problem?
I have the same problem since yesterday!
Btw I have rooted stock Froyo FRG83D, locked bootloader.
I think the app I installed yesterday was SetCPU. I don't know if the problem appeared because of that..
My apps installed on the SD Card are not recognized but I can see my photos in the Gallery which are stored on the SD Card as well! WTH!
Also I cannot install anything from the market..
Any solutions anyone?!?
I think what is screwing up the apps is using CM's ability to move apps to the SD card.
I have reinstalled all the apps using Titanium and have only moved those that you can natively. Will see how this goes.

[Q] (Q) Question Gingerbread 2.3.3 16GB card on EBAY-I'm New in Nook

HI..
I’m new in Nook color. I have just bough nook color and an 16GB SD card with Gingerbread 2.3.3 Mod version Phiremod Nook 6.3 Build No. GRI40.
I have not any problem for 1st time booting, but afterthat market wont work, after several cache & data clear up market is back to normal. Then another problem has been found,
1) Internet connection is really slow. My wi-fi setting is set to WEP security (if i change it to W2K or something else it will not detect my wifi), signal is excelent, but sometime i even cannot get into google,I think there problem with the software and connection, seems the nook is very slow also even when i click a thick box it will take around 2-3 minutes to response. What will be the possible issue?
2) When I want to reboot or powering off the Nook another problem has come, the nook wont reboot neither powering off, it hangs and freakin’ me out and i must hard force the power button to kill the nook. What is the cause?
3) Nook shall come with 8GB internal storage, but why in the Storage it is mentioning the total space is 0.93GB and available space is 874MB. And my SD card(16GB) is only 2.24GB instead of 16GB.
Please help me all expert.
I start love Nook the first time i’ve seen it, but after getting some confusion with this I start to thing twice to have rooted tablet..please help me to start enjoying my nook.
Thanks ALL

There's the thread for Phiremod. I would guess some of your issues might be addressed in that thread.
You aren't going to be able to change the partition sizes without destroying your non-SD card build (presumably the stock Nook ROM).
My recommendation is forget the Phiremod, all that does is remove you from the official CM7 update paths and in turn you get no real benefits, no support and lagging updates and fixes.
Install the latest CM7 nightly(177) onto your emmc, most, if not all of the issues you are having should go away once you've done that.
you can follow this guide

I hope you didn't pay much for that card, because if you want to fix any of these things, you will probably have to start from scratch and make your own, anyway.
Your performance issues very likely relate back to that card. It may be that they used a poor card in the first place, but even if they used a decent card, sometimes SD installs just don't come out quite right and need to be rebuilt from scratch.

That's how newer NCs are partitioned. There's a 5GB partition that you can't see where Barnes & Noble apps, books and magazines would install, and only 1GB for you to sideload. The remainder is used for boot files and recovery images. You can reverse that partitioning so you have 5GB available using the method here: http://forum.xda-developers.com/showthread.php?t=1094371

You may be able to claim the remaining space using a program like EASEUS Partition Manager, assuming it was in fact a 16GB card. If you look at the card in EASEUS on a PC and see a lot of unallocated space, you can extend the partition named /sdcard to take up that space. If the card was set up that carelessly, though, it's very likely the people who made it didn't know what they were doing and the card will never perform well.
Also instead of WEP use WPA2 for best results.
I bought the card less then 50$, the brand is Paxxxxt. The seller has inform me that there might be an issue with the card, because the speed is too slow. He said from thousand of his cards there are 30 something are having this problem, so he send me another card (sanxxxk), it will arrive within next week, hope it will work.
Thanks to all experts.

[Q] Reboot constantly when External SD is in. Logging Possible?

Hello
Recently upgraded my Tab to Overcome 4.1.0.0. Upgrade went fine. Everything also was running fine. When I restore everything to the external SD the Tab seems to go into a cycle of rebooting where tab will come up, you can get in, it runs slow but eventually reboots. If I take the external card out it runs fine. I have formatted the card a couple times and it seems to format fine. Is there a way to turn on some sort of permanent logging to see what is occuring just before the tab reboots.

Grab a different card and try it first.

Don't Think it was the card
Just did a wipe and load of my tab. Loaded cm9 ICS card is in there mind you nothing on it yet but the tab is not rebooting. Unless it is just a certain sector or that I had too much data on it somehow as dumb as that sounds. Still no real answer though. Thanks for the help though.
Ric
bad sdcard can be a real problem.
A new one isn't costing that much, or just grab any from your old phone, even a 2GB one, and try.
you side-tracked it by loading ICS.
The solution could be real.
For anyone arriving here due to a search, the problem is not related to a bad SD card. I had this same problem and took it as an excuse to upgrade to a new Class 10 Lexar. That didn't fix the problem. It's apparently also not related to no-wipe vs wipe; I did a full wipe and restore, and that didn't fix the problem. I eventually tracked the problem down specifically to having apps moved to the SD card.
Overcome 4.1.0 is apparently *really* sensitive to having a lot of apps moved to SD. With no apps on the SD card, it appears to be perfectly stable. It may be possible to have one or two on the SD card without it breaking; I haven't found the exact limit. I do remember that the Kratos edition of Overcome was also a little glitchy with a lot of apps moved to SD, but mostly in that icons wouldn't load properly, not that the system always rebooted.
The fastest fix (which won't require a wipe but WILL require good backups, hope you've been using Titanium Backup regularly) is to drop the external SD card into your computer and delete the ".android_secure" directory. This will require you to restore from backup any of your apps you moved to SD. Unfortunately, if you're like me, only about half of them will fit, so you now get to be choosy (it might be time for some spring cleaning anyway), or start looking for another ROM, as the maintainer of this one has moved on to other things and there will be no further fixes coming.

cm10 nook color 5gb internal problem

It does not install apps to internal media anyway. It installs them to /data unless you tell them to install to SD. And on CM7, if you did not have an SD, you could swap emmc and sdcard so that apps are fooled. Maybe that is how you did it. CM10 does not have that feature implemented get.

Hi Leapinlar. Thanks for tips thread and for the partition repair scripts. I have done multiple intalls to emmc trying to rectify an internal storage issue. Unlike the user above, I'm not trying to install apps to the media partition, just trying to save files(pictures) to internal storage. My media partition is currently 4.2 gigs, but each time I try to save or open the gallery a message pops up that "no sd card is present." I am new to the NC but not to rooting, and have had a really good experiences with CM and Kang builds on a Galaxy S2. I have never used an sd card on my phone and media files save to the internal storage with no issues whatsoever, so I'm wondering if the CM nightlies for NC are so radically different than the JB rom on my phone as to cause errors in accessing the internal storage on the NC. Any thoughts would be appreciated.

Yes, the Nooks are different than many phones. On many phones, the internal media storage is named "sdcard". And external cards end up getting called something like "ext_sdcard". That way when apps look for "sdcard" to store their books, music, whatever, it ends up using internal storage. But for the Nooks, internal storage is called "emmc" and only external cards get called "sdcard ". And since many apps will not run unless it can find "sdcard", CM7 has a setting that lets you swap emmc and sdcard. So internal storage gets called "sdcard" and external cards get called "emmc". That is for users that have no external card inserted. But that is not yet implemented in CM10. So until that does get implemented the work around is to insert an external card. There are hacks you can use, but most are not simple.

Great info, thanks. I'm rather techy, but it's funny how the more you know, the more you realize there is to learn. I only mentioned my phone as it seemed a fair reference point as it is running AKOP JB, and the settings for it and the Nook are all but identical. Storage settings on both devices show two partitions( is that the term?) each labeled "internal storage" the first on each dedicated to data and the second to media. On the Nook that media portion seems inaccessible even from a PC; it shows up as "My Nook Color," or some such, if I connect as an MTP device, but if I attempt to drag and drop a file a message pops up saying the device has stopped or has been disconnected, even though it is clearly visible and connected. I believe your tips has a link for fixing adb/usb(?) but I haven't gotten that far yet. It is fun to be learning a new device and your guides are invaluable. I picked up the NC as a refurb, full warranty, for $75 so it was hard to pass up. Now that I'm fairly certain all partitions are healthy( thank you) I think I will move back to a larger data partition, pop in an sd card and just enjoy the Nook and continue to learn as I go by following your work and suggestions. As an aside, I have had zero performance issues with the CM 10 nightlies beyond a tiny bit of lag here and there and continue to be amazed that there is so much life in the older hardware. Again, thank you.
You may want to try USB mass storage rather than MTP. Go to settings, storage, menu, USB computer connection, and check off mass storage rather than MTP. MTP can be flaky sometimes. After you plug in the cable, you need to go to the notification area and enable the computer connection.

Yes that has been my experience with that protocol with other devices over the years. A day or so ago with usb enabled the PC wouldn't recognize the NC. Last night I went back to the 5/1 partitioning scheme, popped in a 32 gig sd card and went to bed. Tonight I turned on usb storage and my machine picked up the sd card immediately, and I was able to drag and drop a few music files in typical fashion. While the issue of not being able to access that "internal" media storage still perplexes me (I can be extremely O/C about tech working the way it's "supposed to,)" I'm simply not going to sweat 1 gig when I added an additional 32. As my experience with the Nook Color grows, more will be revealed. Thanks

BLU R1-PLUS and also BLU R1-HD - Errors messages while moving APPs to SD

I am currently using a 64GB Sandisk MicroSD Card on my new BLU R1-PLUS cellphone, however I am always having errors messages while moving from internal to the SD memory:
"Unfortunately settings has stopped"
"Not enough storage space"
I am aware that some APPs do not allow to be moved to the SD and that others install themselves to the SD, but the problem I have is with APPs that can be moved to the SD but that when entering "Settings/Storage & USB" it always Crashes.
This annoying problem prevents accessing or manually moving the APPs from internal to SD, because the "Configuration" always closes/crashes, and then I have to uninstall the APPs using only the "Uninstall" function on the home screen.
My Settings/Storage & USB information:
Default write disk SanDisk SD Card
Device Storage 27.37GB Total used of 90.53GB
Internal Storage 11.45GB used of 32GB
SanDisk SD Card 15.92GB used of 58.53GB
I have noticed that when I got this errors messages that if I delete some big APPs the problem totally disapears, so I am starting to believe that may be there is some kind of low memory cache problem, while displaying all the installed APPs on the list at: Settings/Storage & USB
I have made a factory reset several times, have also rebooted into Safe-Mode, and also decided to use other 64GB microSD cards from PNY and Samsung, as I thought some of my memory cards maybe were damaged, but the problem remains the same.
Interestingly, I also experienced the same strange behavior with my other 3 BLU R1-HD cellphones, so it seems that this is not just a problem of the new BLU R1-PLUS.
I am not sure if is the same problem, but Naria9 has mentioned something similar:
"A lot of the general idiosyncrasies of the previous version of the stock rom seem to have gone away for me. It seemed to have weird storage management issues, errors moving to SD, broken symlinks that prevent apps from moving or being reinstalled, and a lot of other little non-storage issues, but so far, none off that here."
https://forum.xda-developers.com/showpost.php?p=72203169&postcount=5
Does anyone of you knows if there is any fix, or have experienced these same issues when moving APPs from the internal memory to the SD, on the New BLU R1-PLUS or the Original BLU R1-HD?
Thanks in advance for helping me with this problem!
I forgot to mention that I currently have 455 APPs installed, downloaded from the Amazon APP Store and also from the Google Play Store...
But as I said before, this problem has happened to me with both the New BLU R1-PLUS and the BLU R1-HD, and never manifests if I install less than 300 APPs, it always manifests itself when I install more than 350-400 APPs... So I'm starting to believe it's a problem of the APP's listing in "Settings/Storage & USB", or maybe some kind of low memory cache.
Some of you who have bought and are using the new BLU R1-PLUS or the original BLU R1-HD, have already been able to test or have experienced these same problems when moving APPs from internal memory to SD?
Could someone recommend me what to do to try and solve this annoying problem?
I would greatly appreciate any help!
After searching for several weeks on YouTube and also on some technical websites, I thought you would like to know that all the problems I have described are apparently not exclusive to BLU R1-PLUS or BLU R1-HD phones.
Apparently there are some serious problems with Android 6, when moving all the APPs from the internal to the SD memory, no matter the brand of the cellphone!
I have already tried with some fixes that others have used to solve this annoying behavior, like the followings ones:
- Disabling and cleaning the cache of the Google APP (System App).
- Reset APPs Preferences, in Settings/Storage & USB/Internal Storage/APPs (selecting right corner menu: Reset APPs Preferences
- Making use if an APP called: Install Button Unlocked v3.2
https://www.amazon.com/SFApps-Install-Button-Unlocker/dp/B01HGKY2KA
Because when I install an APP or APK file, the install button was not working and the this APP can unlock the button which security was caused by "Screen Overlay"
I also have searched in YouTube the following:
"unfortunatelly settings has stopped"
And have found hundreds of fixes that apparently have worked 100% and corrected the same problems that I have mentioned in my 1st post, however I must say that none have worked for me.
Some of you who have bought the new BLU R1-PLUS or are using the original BLU R1-HD, have already been able to test or have experienced these same problems when moving APPs from the internal memory to the SD?
I would greatly appreciate any help to totally or partially solve this annoying behavior!
Can you switch settings?
I have the Blu r1 hd, so I'm not sure if the r1 plus is configured the same. First of all, did you set your phone to use your SD card as internal storage? Some of your apps will remain on your phone, but it will integrate your SD card so that it should run a bit more smoothly. However, you will not be able to use your SD card solely as storage (it will be unusable outside the phone).
I have encountered issues of my own, where the phone runs slower at this setting, and yes, I get "unfortunately... Has stopped," occasionally (actually this started happening now recently). Then my camera stopped working properly so I reset my phone. After reset, my SD card was corrupt and unusable. This reset was only a few days ago, and things work better, but I haven't gotten a new SD card yet. I'll have to see if my previous issues recur, or if my original SD was not working properly.
If you already have your SD card to work as your internal memory, I'm not sure I have any more advice for you (I'm not very tech savvy, sorry).
Thanks for trying to help with this matter!
Yes, set my BLU-R1-PLUS to use my SD card as internal storage, and I know that some of the apps will remain on the phone, but it will integrate and use this SD card so that it can run a bit more smoothly.
I am also aware that if when a SD card is assigned and formatted as internal storage, it will be unusable outside the phone, and therefore it will not be readable in other operating systems or PCs.
As I mentioned in my first posts, the biggest problem with the BLU-R1-PLUS is that when allocating a microSD memory as internal memory and installing more than 300-400 APPs, it seems that the Android6 system does not support having so many APPs installed or perhaps the memory gets congested or fragmented?
Interestingly, as I have 6 BLU-R1HD, I have also found that this same problem occurs with all my BLU-R1HD with Android-6.
I have also seen some videos on YouTube, and I have read that this seems to be a very common problem in cell phones with Andro6.
I say this because I also have a BLU-VIVO-8, with a 128GB microSD memory card (used as internal memory) and installed more than 600 APPs and up to 900 APPs, and I have not noticed this problem.
So, I'm starting to believe that as the BLU-VIVO-8 comes with Android Nougat-7, maybe Google has already corrected all these memory problems in this new version 7 of Android.
In addition, as the BLU-VIVO-8 has 4GB of memory and 64GB of Storage, it may be that today's Android system is requiring more memory and the 4GB of Vivo8 make this phone work more smoothly.
Have you folks tried switching to a different mSD card, different/smaller capacity ?
I had issues running debloated v8.4 and 8.5 earlier - properly formatting (FAT32) a new mSD card (Class 10) with my Linux desktop PC seemed to help, or least the problem hasn't returned ... yet.
The older mSD card is now used in a backup Motorola Moto E (running stock Android 5.x) and no errors, used it for storing images & mp4's mostly.
Keep in mind the Blu R1HD is really a $50+ basic but reliable smartphone, most of us running almost stock Android without bloatware - and it is NOT a mid-level one with all the bells & whistles, let alone a high end device ... I.M.H.O. - loading 100+ Apps on it, moving them to the mSD card is just going to put lots of extra "demands" on the hardware & OS, grounds for trouble & things to go off tracks.
My SIL is using the 2nd. one, both running V9.0 with the newest Security patches - Super SU on it, Magisk on the other - Xposed Installer & Gravity Box only with SU ... haven't noticed any mSD errors for last 3 months, used to drive me crazy with the random errors when rebooting or starting it up, losing the contents & had to restore/move/copy them back again from cloud storage.

Letitride, thanks for trying to help with this matter!
Yes, I already tested with different brands of microSD cards, of different capacities: 16 GB, 32 GB, 64 GB and 128 GB, and these problems always appeared in the BLU-R1-PLUS and the BLU-R1HD, but as I said before, in my new BLU-VIVO-8 they have never manifested.
So, I think you could be right, it seems that when you install more than 100 applications on these low-end phones and move them to the microSD card, this imposes many additional "demands" on the hardware and operating system, which could cause problems and damage to the data in this microSD card, after a certain time of using the cellphone.
