[SOLVED] Apps2SD problem with sd

I had apps2sd by lucidrem running on my phone and it was fine. I was out today and my sd card was 'removed' although I didn't touch it. This ended up bricking my phone, because the sd is removed and there is no data or delvik etc. Is there a method to use apps2sd without it being permanently affected when an sd is removed?
A reinstall of rom has fixed it however I have lost everything off the phone now
Thanks

LucidRem's Apps2SD uses symlinks which I believe is now preferred over the one used by MarcusMaximus (forgot what its called ) only way to remove a sdcard safely without screwing up your phone is if the phone is turned off. No idea how the sdcard was 'removed' if you didn't touch it. Happened sometimes to me, but never found out what caused it. Hope this helps.

Best to apply Apps2SD again really or use a ROM that automatically enables it by default if a partition exists (Cyanogen/Dude).
Also a small sidenote... The term "brick" means your device would no longer be functional at all, I.E Unable to turn it on using any method. A more suitable term would probably be "crashed" instead.
I only mention this because the term bricked is being used far too loosely to describe the wrong symptoms.

Sorry for loosing brick loosly, just presumed that was what it was when the phone won't get past the G1 splash. So, say I want to watch a movie or something on a different memory card (won't be able to fit all my stuff on one) all I have to do is switch phone off, remove memory card, insert different one (preferably also with a2sd configured for meridian video?) and that will work?
I think the problem is with movement and sudden knocks that the card comes out. I was running through a storm when it said memory card was removed.
Thanks

No worries about the terms as there are an awful lot of them in the world of technology! Long as we're all learning then we can't argue ^_^
To be honest, hot swapping SD cards is a bit long winded... Its best to save up and invest in a larger memory card if possible (Class 6). Not sure what size your SD card is, but if it can't hold a movie then it could be time to buy a new one.
Also if you use the older Apps2SD program (1.1 I believe) it uses Symlinks as alritewhadeva mentioned and it shouldn't cause your phone to crash totally if the SD card is removed.
Best solution though is to buy a new SD card, you should be able to find one on the cheap on the net.

its an 8gb C4, however I am travelling and will be on a 10 hour flight later this month, and was wanting lots of films and tv shows etc. May just compress and squeeze them onto my 8GB.
Thanks a lot

using a2sd and 2 memory cards doesnt work. All your app data and cache is on your sd card and the phone wont be able to boot without the right sd card in the phone (trust me i have tried). I suggest buying a new card maybe 16 gb.

Hope they have a charging point on your flight! It would kill your battery watching a movie for that long haha. Better off with an iPod/MP3 player I reckon.
But yeah, you can either add more compression or reduce the resolution/framerate to fit more on your SD card. Quality will drop but at least it will keep you entertained.

2 batteries plus a portable battery charger ftw

Haha, that should be sufficient then! Very well prepared ^_^ I was thinking about getting one of those wind up backup chargers for emergancy use once... No idea if its any good.
If everything is sorted tuka, could you please edit the title to add "[SOLVED]" so people know? Thanks!

Transferring Files (movies/music) TO SD Card Issue

I have a brand new rooted BN Nook Color. I did not do the rooting and install, but here is what I know. It is installed on the internal memory and from what I can tell the SD Card is holding App info and whatever movies/music I can get moved...which is absolute luck when it happens.
So here is what happens, I drag and drop a file to the mounted SD card and it begins to transfer. At some point in the transfer it will error out and stop the transfer. Now, I have had some luck...I just keep banging away and eventually I might 1 or 2 over there in a 4-5 hour period.
Here is the weird part, I thought maybe it was the source file on my Windows 7 box....so I decided to drop it in the internal memory, and it worked. So i figured I would just move it to the SD card via file manager on the Nook...nope it causes a force close.
Now as I stated I have had a few make it over, that was luck I believe because I have had the ones that made it over also fail a dozen or more times at some point. I have tried it mounted in the Nook and have tried it actually in the PC, multiple PC's....same thing everytime.
SD Card Issue???
Any help would be greatly appreciated.

Phone randomly unmounts SD card?

Trying to figure out what's going on here. Switched from CM7.1, which wouldn't mount the card at all, to Apex 10.1, which mounts it a bit more regularly. However, sometime between 30 minutes to two and a half hours after mounting, the phone claims the card has been "removed unexpectedly," and the tries to remount it and claims the card is blank or corrupt. I've tried mounting it on my PC, seems to work fine. Does this sound like more of a hardware issue with my Captivate, or with the SD card?
Oh, and it re-mounts just fine if I go through the menu and tell it to remount the card.

[Q] Unmodified i9000: SD card suddenly empty

Any clues why?
As said, Samsung Galaxy S i9000 without any modifications apart from an official 2.2 to 2.3 Android upgrade from Samsung.
The phone got dropped before it was noticed, but not particularly hard.
The SD card was empty apart from two (empty) directories:
.andriod_secure
LOST.DIR
I ran RECUVA and it ONLY found 6 MP3 files, but none of the important movieclips of the kids in Eurodisney... The 6 MP3 files were in excellent shape, there were no other files found either in good or bad shape.
It's the wife's phone. She has older backups, but the backup after the Disney visit didn't work and she thought, meh, I'll try again in a while. Bad decision...
- What happened here?
- Did the phone actively wipe the card somehow?
- Can dropping a phone wipe an SD card (or can you think of any situation where this could even be remotely possible, like while writing to it)?
- Anything else I should try?
On a more technical level: how does an SD card work? Magnetically stored info on a platter of an old fashioned harddrive stays there after deleting the TOC (or whachamacallit, I thought this is what happens if you delete/format it). But the bits on an SD card also stay where they are after a simple 'delete' or 'format' action, right? So does that give an indication what happened, since I could only recover 35MB out of ~6GB used data? (8GB class 4 Sandisk)
As I understand it, electricity is used to write flash memory, but once it is in there, it stays in there.
(BTW, I worked in a company using flash memory in a device that would sometimes have an empty battery or where the PCB would even literally drown. The lack of battery power was clearly visible in a block of data, it started out normally, but would end in FF's (as seen with UltraEdit), a clear sign that this block had been wiped (all bytes set to FF), but while writing, it failed to finish writing the entire block. The drowning victims, we would remove the chip and place it on an external-read-out board and still be able to salvage data, even with half rotted pins on the chip :raz:. )

SD Card formatted as internal storage randomly unusable on cm13

I love marshmallow's adoptable storage feature, allowing me to install more apps. This feature worked beautifully for about a month and a half. However, I shut down the device, plugged it in to charge, went to sleep, and the next morning, the apps that were moved to the sd card were not available anymore. They were all greyed out on my launcher(Nova). I moved about 4 gigs worth of mostly games. Fortunately, most of them had cloud storage, but some favorite games didnt. This isn't that big of a problem, but I'd like to try to fix it. So, I went here for help.
At first, I thought the class 10 SanDisk 16gb sd had just gotten bumped out of the slot where the connections happen, so I opened the back cover and removed and inserted the sd card. The notification that prompted me to put the sd back in went away for a few seconds, but then came back. I repeated the process of removing and inserting the sd a few times, but still no moved apps were available. I put the sd into an adapter, then into my laptop, and it showed on file explorer. So the sd card could still be recognized, but maybe unusable.
I dont know what happened, one day it was working, the next day it wasn't. I know i formatted it as internal and portable storage a few times, so maybe that wore it out. I'm running cm13

Hello,
On my phone I used the micro SD card normally as external storage. On day I plugged in my headphones and there was no music. I though that the micro SD card must have come out. However, reinserted it it didn't work. I wouldn't open on computer either. While I don't have a solution, I am pretty sure I also had the same problem.

Once I was taking pictures with my phone when it crashed and rebooted. Some hours before the crash I uninstalled some apps and installed some others (but never rebooted the phone). After the phone started again after the crash, all the pictures and files were gone, the uninstalled apps were there as if I've never uninstalled them and the new installed ones dissapeared.

how long have you used your sd card? i'm sure that the more you use a micro sd card, the more it will wear out and become unuseable/corrupted. That has happened to me before, where the sd card just stopped working.

I have used it for about 1 year. So it may be that but, it has never occurred before.

Same problem here, you can read it here. While I am writing hopefully my files from Titanium Backup are transfered to my laptop. It got worse and worse, in my opinion the sd-card has reached it's end of life because of it's heavy usage. Error occured the first time after the phone got really hot recording gpx tracks. Bye bye sd-card
Another opinion is that warranty is over after two years, so the phone can quit it's duty now - obsolescense plans

yeah, i'm starting to think my micro sd just bailed from wear like that too, but i got to use mine for just over 3 months. i ejected the sd and put it into my computer, and interestingly enough, on my computer it reads 16 megabytes. i was like WAAT that cant be, i formatted it, put it back in my phone as portable, and it read as the normal 14gb. i'm starting to think my sd as internal is the cause of my random reboots. im even running the lastest cm13 update too...
i guess ill try and use my sd as just portable storage from now on, and see if i get any random reboots..

I switched to TurboROM which is using the sd-card as a portable media device, so no more encryption, heavy usage and complete data loss if you do not get your encryption key with root permission.
System space left after complete recovery of my apps with TB is quite nice - but you do not have the possibility to use App2SD (correct me if I am wrong).
So the only way to save internal system space is to move pictures, movies and heavy openstreetmap cards to external.
