[Q] Cannot boot from microSD card - Nook Color General

Hi all.
I have been trying to install CM7/gingerbread over the past couple of days to no availe.
First I tried my 16gb card and now I've tried my 4gb card. Unfortunately, I don't have any smaller, or non SDhc, cards around.
Tried holding the power button, but that doesn't seem to make a difference. I have attatched a screen capture of the sd card contents. The "extra" folders at the top were not originally there, but were added when it launched into the normal OS.
One thing that came to mind is I have installed ClockworksMod to internal memory earlier. Could that be screwing up my being able to boot the SD card?

I found my Nook Color was very finicky about the card. It did not like the Transcend 4 GB class 6 that I had, but worked on some generic 2 GB card that I had leftover.
See if you can get a cheap brand name 2 or 4 GB card and try it with that.

SD Card Corruption with Nexus One (has happened twice)

Twice in the last two months my 16 GB Class 6 AData microSDHC memory card has popped up as being "corrupt" and needed reformatting after powering back up from reboot on my Nexus One.
The first time happened on CM 5.0.3.1, the second time was with CM 5.0.4.1 with the UV kernel. Both times, data could not be read either through the N1, my old G1, or my friend's Droid. Thus a reformat was required and data loss ensued.
Anyone else experiencing occasional data corruption on their SD card? Another friend had it happen to his G1 with an 8 GB microSDHC memory card recently, running the latest CM for the G1, also on reboot and battery swap.
Is there a common thread here? Could it be HTC hardware-related? CM software-related? Just coincidentally two bad memory cards? Me using chinese replacement batteries when swapping out? The UV kernel? Not trying to point fingers or throw stones, just trying to get to the bottom of this...just lost some great pics of a recent vacation I just got back from. Suggestions or hints are welcome!
TIA!
this has happened to me a few times but I was still able to get my data through amon-ra recovery. I think it have something to do with an improper dismount of the card.
I'm curious, what brand of memory were your friends using?
I actually had this happen when my n1 was still stock (16gb class6 card)
I put the sd card in a card reader on my pc, everything was intact so I backed it up, reformatted and still had the n1 report it was corrupt. I ended up having to shut down, remove card, boot up w/o a sd card in, then with the sd card back in I never had the problem again
I know I did a full format the very first time, that 2nd time I had done a quick format. I've done a format recently also via amonra for ext partition and still no problems.
I happend to me few weeks ago. After turned it on ... I couldn't do anything because the screen was black and any key or type of touch was useful ... so I removed the battery and at the next start the SD wasn't readable anymore!
sry 4 my bad english!
erikikaz:
i'm running a 16 GD Class 6 AData memcard in my N1, my friend is running an 8 GB class 6 SanDisk memcard in his G1. Neither of us is running Apps2SD or anything weird.
glad to see i'm not the only one with this issue. was gonna buy a new 16 GB card but saw an article yesterday that sandisk is coming out with a 32 GB class 6 sdhc card in a month so i'll just wait for that one.
Same here
Same thing has happened three times on my Sandisk 16gb. I am running stock everything on nexus..nothing funky app wise.
After the first time it happened I replaced the sd card. It still happens. I have never been able to fix the card other than reformating. Chkdsk /f on win7 gets to 98% then throws an i/o error.
There is something majorly wrong. It seems that it happens in all android phones from time to time not just the nexus one. The consensus online seems to be that it is a mount/dismount issue that corrupts the card. I never mounted or dismounted the card at all with PC and it still happens so not sure what else it could be.
Do you think it is a phone hardware issue that would resolve with a new handset?
Has this ever happened to anybody using the standard 4GB card?
Where did you purchase your micro SD cards? There are a lot of fake/faulty cards being sold. I bought a fake one (unknowingly, obviously) and it kept getting corrupted until I tested it properly using h2testw.
I have the same problem on my nexus! I use an LG 16GB Card and CyanogenMod-5.0.5.3-N1! Any way of recovering the data without amon-ra?

+1 Make sure you dismount from computer first...otherwise this problem will pop up again...and may not be correctable next time. (There's a reason why the phone asks you to properly dismount from computer first)
no **** my n1 has the error message damaged sd card. restarted the phone a couple times and same message. what should i do? i see peoples solutions on this thread but idk where to start. i have a rooted n1 running cyan 5053 with apps2sd
I have had this problem a couple of times too, the latest being this morning
I have a stock N1 with a 16GB Sandisk card. The first time this happened, i went to use the camera and it said insert SD card, even though there was one there, I rebooted the phone and then got the Damaged SD card message.
This morning I was on the train, had been using the phone to read the news earlier with no problems, I got it out of my pocket and screen was black. and the phone completely unresponsive. Removed and replaced battery, booted up and got the Damaged sd card message again.
Both times I have been able to recover most of my files by putting the card in a PC, the first time I found that a couple of my photos were corrupted and unrecoverable, indicating that possibly it was the camera app that may have caused the issue the first time.
This time though, I found that some of my music tracks were corrupted along with one of my videos, and also a directory on the SD called LOST.DIR. Everything else was fine.
Not sure why only these files were affected, as I was not listening to music or watching any videos, so I dont see why the nexus one should have been accessing those parts of the card when it corrupted.
I could not delete the corrupted files, even on my PC, accessing them causes the PC to lock up. The only way to get card working again seems to be a format.
If only the format would work!

Just happened to me as well. Genuine 8gb Sandisk, class 4.
After a reboot Nexus reports corrupted card. It really seems corrupted, I'm unable to read it in a PC or anything else:
[ 1042.673542] sd 11:0:0:0: [sdb] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE
[ 1042.673551] sd 11:0:0:0: [sdb] Sense Key : Medium Error [current]
[ 1042.673561] sd 11:0:0:0: [sdb] Add. Sense: Unrecovered read error
[ 1042.673571] end_request: I/O error, dev sdb, sector 10248
I'm using CM 5.0.4.1 with UV kernel.
It's happened to me, even using the "safely remove hardware" function on the pc. i started just using the unmount on the phone which seemed less problematic.
Yep...add me to the list. Running stock N1 was playing music when it ocurred it started skipping through the tracks fast right before it stopped. It has affected/removed all my pics and left the music.
I'm with you all:
2 times on my Motorola Milestone, using a 16GB class 4 "unbranded" card
3 times on my Nexus, using that same 16GB class 4 card.
2 times on my Nexus, with a 16GB class 6 SanDisk card.
Most times, the data has been available by mounting the card into a PC or Mac directly, though my Mac has seen the card as "read-only" in these cases.
I seem to have this problem after mounting the card onto my work PC, though I don't often do that. I mostly use ADB to copy files. Maybe it is linked to leaving the debugging interface up all the time? I do that and I'm sure that most of you do as well...
Me too
I am using FRF91 MRCr21 and I am on a 800mv 070810 .35 rc4 kernel. Newest 5.00.08.04 radio.
Twice now after using quickboot my phone has reported my SD card damaged and it says I will have to reformat. It is a 8gb class 2 sandisk, real. One time I used quickboot to enter recovery mode and the other was only to reboot the phone. Has anyone else had this problem? What is the best fix? Both times I rebooted my phone was stable. I wasn't downloading or installing anything. Thanks!
My phone can't read the card. If I pull the card and put it directly in my computer it won't read either. Both OS can't read the file system and want me to reformat.
Neither happened due to not dismounting. Anyone correlate the problem with quickboot?
have had zero luck with adata 16GB classs 6 cards. i have gone through 2 of them however their 8 GB card has been awesome
Just had this with a Sandisk 16GB Class 2 card. Inserted into card reader, copied something, popped it back into the phone, corrupt card message. Even the computer says I have to format it.

[Q] microSD card help.

i had no real idea where to put this, so since i will be using it in my nook i figured id try here.
Wintec microSD class10 16Gb
i bought this new micro SD card for my nook. i put it into my card reader to format it (fat32 is the only option).
when i quick format it goes fine, then i try and put stuff on it and i get a dependency error and windows explorer crashes (not responding).
when i do the regular format, it gets all the way to the end and says "fromat can not be completed" and windows explorer crashes (not responding).
try it in another computer with the exact same results. is the SD card bad? i havent done anything with it. i took it out of the package and straight into the card reader.
bought it from newegg. should i contact newegg first or wintec?
You aren't the only one that has had problems with that card.
I have one and it works, but speeds are class 4 at best. A little under that actually.

Weird characters in SD card

Hey all, recently my external SD card has been developing all sorts of weird characters in it, and all my files are now gone. I have no idea what could be causing it, but there is upwards of 160 of these weird files on there, and I have no idea why. Any thoughts?
I also attached a screenshot of what it looks like from Windows. Thanks.
try reformatting it, make sure when you do its FAT 32 and not ntfs.
Is this a card you bought off eBay? Lots of counterfeit cards there that won't hold data reliably.
It's actually a card straight from Sandisk. I had purchased a 16 gig when I got my Windows Phone 7, then came to find out that 7 pwned sd cards. So I had it RMAed with Sandisk and they sent me a brand new one.
If it helps, I am running Firefly 3.0, Speedmod K13e, and JL3 modem. This only started happening after the update to 3.0.

[Q] Problems with installing cm7 to booth from 16gb class 6 microsd card

I am a newbie, still on original nook firmware think its 1.01
I am having trouble trying to install cm7 on a 16gb microsd card. I had a look in XDA and there are a few people having the same problems awhile ago, and then there are some who have managed to do it. I have trawled thru quite a few pages int he foru but can't seem to find a solution. Anyone here has any luck with installing cm7 to boot from a 16gb microsd? Any comments would be appreciated.
My problem seem to be, after i imaged the microsd and then copied the update night;y cm7. zip file across, the nook booth from the microsd but and setsups but then just hangs after superfiles(?) have been installed, whereas the guide saystehat it will ventually go to a blanks screen, which mine never does, then when i force shuitdown and reboot, it installls some android files but when it reboots after that it either hangs onthe ANDROID_ screen (keeps rebooting over and over again) or it goes to the cyogenm7 graphic screen and keeps rebooting to the startup screen.
Thanks
Try a different SD card, preferably 8G or less. Quite a few cards don't play nice. If you can get CM7 installed on a different card but still want to try it on your 16G card, you can image it over from your other working card. You'd then need to expand the 4th partition to reclaim the space then. It may work, or you may get random quirkiness using that card with force closes here and there.
I'd make sure to get a genuine SD card from a reputable dealer, not some dodgy one off Ebay. I have found Sandisk to be very reliable, and generally a cheaper Class 2 or 4 card will work better due to higher speeds with small random block r/w.
Good luck.

SD Card Read only?

Greetings!
I purchased a new SD card from SanDisk with 400GB.(didn't use my old one on this phone because of low storage size)
My problem is that i'm unable to copy/move/delete files to my SD card.
I can't even create a new folder.
I tried several explorers and activated the permissions for writing but no success.
I was also trying another SD card but the same problem.
If I format the card over my phone as internal storage the phone freezes, formatting as external storage is working though.
I also formatted the card on my PC but still the same issue.
Remounting the card in the settings sometimes works for a few seconds.(creating a folder,etc..)
My razer phone 2 has the newest FW with Android 9.

Heya buddy,
Just a quick enquiry, from where did you purchase your MICROSD? it sounds like you may have a fake card, the memory size is worrying indication, normally cards are sold in denominations of 32, 64, 128, 512,GB not 400 GB. Have you run a check to see if it's reporting the correct capacity size on a SD card checker. Sounds like it's a fake and when it tries to format, it goes into a loop state and crashes as the card is formatted over and over and over trying to reach the stated size but never reaches it due to it not being 400gb in size.
Sorry to spread the bad news, have had the same happen to me, I am so dam careful over which company I buy my cards from.
Let me know if I can help.
Yours

Phone says it has 393GB.
I bought it on amazon. Its a SanDisk Ultra 400GB that also appears on the official homepage. I'm pretty sure its not a fake.

Ok, that clears up the possibility of it being fake good good..
..hmmmmm. Do you have any old phones at your disposal that have a card slot? If so,. Try it in those and see if you can access it and read/write/modify files on it. Maybe format it with another device and then stick it in the razer and see if it works.
I'm sure now that cards a real deal as Amazon don't seem to allow frauds to be sold the only other thing I can think of is that it's a faulty card, it happens, they are just mass produced. Maybe a replacement if it's dudd.
I am having an SD card issue as well. I have had my Razer Phone 2 since last Monday brand new from Ebay. I purchased a Samsung 128GB class 10 (u3) SD card for it from Amazon. If I format the SD card as "internal", it shows that there is 131GB's of system files on my SD card. It shows I'm using 131GB's of storage from a total of 320GB's. The Razer Phone 2 has 64GB;s plus my 128GB SD card which would be 192GB;s total. I have tried many file manager apps, move to SD apps, etc and I cannot transfer any files. When I format the 128GB SD card as "portable", it shows the correct amount of storage space in both the phone and the card but once again I cannot transfer any files to the card. I have tried a 16GB SD card as well. The phone did recognize it and read the available storage on the phone and the card correctly. I did not format that card as I have music, photos and documents on it. I did try to transfer an app from my phone to the 16GB card and once again I could not do that. Any help would be appreciated. Thank you in advance and take care.
I have had similar problems with my Razer2. It ruined a 512g scandisk brand microsd card. Copying, or moving files, is a real problem for this device! It hangs up sometimes and ruins the files. Never had these issues, this bad, with any other phone
I have a bunch of music on my SD card, my music app sees some of them. If I move the whole folder to my phone storage, music app sees all. If I boot to twrp (per arters kernel) and try to backup to external SD card, it fails. If I save it to the phone, works fine. It's like it doesn't constantly see the SD card slot properly.
Exfat is needed with art kernel. Stock formats as vfat a old file system. I have a 400gb exfat formatted and works perfectly
I'll have to look into getting that kernal
