SD Card freezes phone/stuck when trying to back it up - Android Q&A, Help & Troubleshooting

Hi,
Just this night I've been using my sdcard in a normal way, browsing internet, downloading files when suddenly my phone couldn't boot after flashing bootanimation (zip made by trusted developer so that's not the problem). Now when I connect my SD Card to the phone it will either say "preparing sdcard" forever or just simply freeze phone after few seconds. I tryed to connect it via working adapter with my PC to back it up... After copying few files sdcards unmounts from the reader... I've tryed on XP and it shows some command errors while trying to copy files in a regular way. I was ONCE able to flash few zips via recovery in order to make my phone boot up again it worked. Now I'm scanning my SD Card using Norton Internet security 2013 - Paid version - not cracked, and the sdcard seems to stay mounted to the PC. Unfortunately after trying to copy files from SD Card to PC it just freezes explorer.exe and unmounts itself...
Please help me, I really have some important pictures on this sd card
PS. 32 GB SanDisk Class 10 UHS-I (grey and red one)
PS. 2 I was using swap partition, maybe my sdcard went dead from constant reads and writes?
PS. 3 Using linux I managed to copy 81 MB... then any copying froze but ubuntu didn't... Damn, thats weird

It appears to randomly stop reading from SD Card as now it stopped at 153,1MB out of 422MB, all thumbnails of photos were shown properly though.

well first connect ur sdcard to an old mobile you have then connect mobile to computer
backup your data then use a partition tool to delete partition of sdcard then recreate it as FAT32 partition and try to put sdcard to your mobile again
if still, then wipe data/factory reseyt your rom
if doesn't work then let me know

Well, connecting to an old mobile isnt an option as the SDCARD does the same thing even on xperia T which isnt that bad and that Xperia T never had this sdcard connected before.
I'd love to backup my data, but I can't
Full rom wipe and reflash fresh was done straight after getting problems with this sdcard.
Unfortunately it still doesn't work

I got the error I was talking about!

EDIT: I'm trying to recover photos and movies (most important files) via BadCopy Pro, any other recommendations if it wouldn't work?
EDIT2: It seems that when I'm slowly copying data (scanning sectors) sdcard doesn't seem to unmount or do other crazy stuff, any other suggestions so I'll keep file names and structure? I don't care much about copying time, I can run copying going all night.

I've recovered like 90% of data. Afterwards I've tried to perform Low Level Format... But this goddamn sdcard had to eject just at the start, therefore partitions got deleted, I'm trying to rebuild bootsector with testdisk but it takes ages, even after looking at tutorials online it takes so long to rebuild bootsector, no idea why...

I just realised that im one of the "lucky" guys which have got faulty sdcard. It happens to small amount (they say) of sandisk ultra 32&64GB owners...

then use the warranty to change your card, when you buy something, you're supposed to get it fully working

Yeah, Ive already written to sandisk but their 2 final and most important messages were one in german abd second in english. Im glad that i have a private teacher which helps me in german and is getting me ready for FCE exam so he can translate german to normal language
Another problem is that this card was a gift on my name day and im not sure when it has been bought although i know where. Thats my problem now but you definitely cant help me with it.
Thanks anyway

How to upgrade/replace the Micro SD card

Hi,
I am planning to buy a 16GB Micro SD Card for X10 Mini, need help on following
1. Can I buy any 16GB micro sd card (class 6 and above) will it work, or it has to be specifically from SE?
2. Once I have 16GB micro sd card, what are the steps to replace the existing card and its contents. Do i need to copy all the folders from existing micro sd to new sd card? What should be the format of SD card, fat, fat32, ext2/3/4 ? Kindly suggest.
Any other technicalities to take care off ?
Furthermore I would like to use APPtoSD either on 2.1 if its easy or else when 2.2 gets on, so do i need to prepare the new sd card specifically for this?
Thanks
1) don't know, I bought a 16GB online from sandisk and it works well, i can help if you can tell how to get the "class"
2) my sd is in fat32 as the old one so no problems here. I suppose that if you move from fat32 to ext* you need to handle permissions somehow. I use a linux distro and when I do this moves I use the command "cp -a" that preserves permission (doesn't matter for fat) and modification date so if some software relies on modification dates of files it doesn't screw up
Thanks,
Class is written on top of the card. See the attached image the 6 witten inside the circle shows the class.

Does putting in a 16Gb card reduced the performance or increased the lags?
CM 7
I've looked around at a lot of places and haven't found a clear answer to this one yet.
I’ve read a lot of different posts about what the best way to do this is. Some say just copy and paste, some say you need to go into recovery mode and Format the SD to Fat32+ext2+swap first and then convert ext2 to ext3, and some say to use Titanium Backup, and there are other opinions too.
I’m really quite happy with the way the phone is set up at the moment and don’t want to mess things up. My X10 mini, has cyanogen mod 7, and clockwork mod. Some of the apps have been moved to the SD card.
Can anyone tell me the current best method?
Thank you ....
Does anyone have any suggestions?

I'm also very interested in how to do this.
Basically use whatever format worked for you with your previous SD card. Oh, another forum member from the x10 forums was told by a Sony Ericsson rep that SD cards above class 4 would not give any further speed boost, but that's for the X10. I think that the same should apply for the x10 mini. Higher classes makes for faster loading of media and games moved to SD card, but actual playing(i.e after it has fully loaded) will be no faster. It will make SWAP faster, though.
Did I answer your question? Please press the Thanks button!
I have tried a 32gb card but it dosn't recognise it
Anyone knows if the new Custom Roms / Kernel make the Mini Pro recognise a 32gb SD card?
Well I checked the original card that came with the phone and it was FAT. The new card was preformatted to FAT32.
I left the new card at FAT32 and plugged them both into a Windows PC and copied the whole lot over. This worked fine.
I suspect that the whole ext2 ext3 thing is to allow the phone to treat that partition as if it were internal memory. Useful if the phone memory is already full.

I recently upgraded my sd card from 2G to 4G, I just copied and pasted files. This seemed to work but since the upgrade I am having trouble flashing roms in cwm recovery. I get an error saying zip (bad) installation aborted.
Not sure if it is related but one to think about.

format internal SD

After a bad flash my Vibrant is not seeing my internal sd card.
Is there a way to reformat?
Settings -> SD card and phone storage -> under phone storage select Format SD card.
Before you do that I would try flashing the mounting fix that was posted a while back in clockwork though. That might help.

The same thing...
Hitting Format SD card under the phone storage part of the screen will format the internal memory. If that doesnt work you should odin back to stock and reflash whatever ROM you want.
Formatting storage card does nothing.
Odin back to stock then reflash your ROM.

Already done that twice.
Hence my question.
Is there a way ie through adb to format the internal Sd/storage memory
This thread is relevant to my interests.
I have attempted to odin, and heimdall back to stock, but either the guide here on XDA is severely outdated, or something is wrong with my vibrant.m (followed steps to a T, but to no avail)
I am extremely technologically adept so anyone willing to talk me through this won't be assisting grandpa through a reformatting, and re-installation of the latest version of windoze operating system on their virus ridden store bought PC so to speak, but rather would be helping out a fellow modder restore his phone, and squeeze a few more months out of it before being forced to upgrade.
Thanks in advance for any help you can provide.
//edit
obviously i can get into the bootloader, recovery, and download mode, but cannot load any rom because i get the error cannot write to lums message.
I too flashed probably once too many times, and something corrupted my internal SD card on my SGS Vibrant, and there's no way to reformat it that I know of.
Are you locked out of the internal SD ie the EU bug?
What ROM were you running when you tried Odin?
Does Odin recognize your device, do you have a lighted com port?
Which version of Odin did you try?
Which files did you plug in on Odin?
And have you tried the AIO toolbox?
No tickee, no laundry!
sorry I didn't see this reply earlier, but since my last posting I bit the bullet and upgraded to a Samsung Galaxy Note 2.
I would however like to see if I could still repair my vibrant for use as another android phone to play with. Odin, etc. all recognize and will flash my phone, but in cwm I can't flash any roms. I it says something about unable to write to lums?

[Q] SdCard stuck on "read only"

Just wondering if anybody has had this issue before. I searched around a bit but haven't found a clear answer yet. After flashing a kernel through Kernel Manager Pro, the phone rebooted, checked sdcard as usual, then popped up that there was an error and sdcard was mounted as "read only". I had made a backup right before flashing the kernel like I usually do so I restored that backup but got the same error. I booted into recovery and wiped data and cache and so on and rebooted into android. No luck with that either, so I tried a backup of a different rom I had. Still the same issue (also wiped between restoring backups for good measure). Plugging it into the computer would work because it would not recognize the sdcard as a removable drive (had the "use as disk drive" option chose on my phone to clarify). Finally I had to boot into recovery, mount usb storage, right click on the drive that my phone was, and click "check and fix for errors". After a very long wait it finished and I unmounted usb storage and rebooted into android again. That finally fixed it (whew), and now I have a folder on my sdcard that is titled "FOUND.0000", and there are text files in it with names such as "FOUND.0000CHK, FOUND.0001CHK" and so on. Do I need these files anymore or is just showing me what was wrong and fixed on my sdcard? Will it cause any issues if I delete the folder? Sorry if all this is confusing or stupid. I just have never had an issue like this before and I have rooted and used quite a few android phones and tablets. Im not a noob but I definitely do not know that much about this kind of stuff so any help would be greatly appreciated! TIA

This is very interesting. I've never had a problem with the SD card. Is this the same SD card that shipped with the phone?
When you, "right click on the drive that my phone was, and click "check and fix for errors" is that a windows command? Does the picture below represent the action you took?

Did you end up deleting those files? If so, what happened?
I am having some weird errors with my SDcard myself. I went from a flashed kernel on CM7 off to another ROM. Rebooted and SDcard errors out the wazoo. I am getting MD5 mismatches on a lot of my backups at that. If I can get a ROM that fully boots, I will likely wipe the sdcard and start over to see if it isn't from a corrupt file or something.
The same exact thing happened to me. I mounted my SD card from recovery and windows auto fixed it.
If that didn't work I was going to wipe backup. wipe, and reformat.

[Q] SD card slow to mount at boot

I've tried searching this issue with no luck, surprisingly! I thought it would be more common.
Anyway, when I boot up my Nexus One, it takes <Sandlot>FOR-EVV-ERRR</Sandlot> to mount my SD card. I've got most of my apps on that card, so it's super annoying!
Like I've said, I've got a bunch of apps (40?) loaded on to this card, a few documents, 4 CDs... random stuff. I haven't formatted the card in a looong time... nor have I wiped the phone in a loooong time. I am a crackflasher - I flash a new ROM every day, but I VERY RARELY have issues, so that's why I haven't wiped in so long. This is really the only issue I have, and, if somebody knows the command, I would be happy to just mount the SD manually through the terminal when I need it to.
The phone is a Nexus One. I'm running a CM7.1(or whatever it is) based ROM and kernel. The SD card is the 16gig one that came with the phone.
Any help is appreciated!
Billy
Cliffnotes: What's the terminal command to mount the SD card to the phone? So the ROM can access it?
Ok, so I guess I diagnosed this issue... after rebooting my phone and waiting for my apps to become available I was able to, through the settings menu, view the space used/available on the SD card. Sooo... it is mounted? And the delay is just Android loading the apps from the SD card? How can I speed that up?
Thanks,

You increase the read/write speed by increasing the SD card cache size. You can use an SD speed boost app to do so easily, there are a couple on the market. There's also a script that you can run.
I had a similar issue. I've been running the same rom for over six months, and initially just flashed updates over the existing version and only wiped caches. I'd strongly recommend that you go ahead and perform a full wipe. It may seem like a pain, but I am 95%, certain that it will fix your issue. Just backup your apps & data with Titanium Backup and after you've completely wiped & flashed your new rom only restore what you need. Weeding out unused apps should speed up your phone as well. You can always restore them if you need them.

Hi, I've been wondering why my P500 on the stock rom 2.3.3 has been taking about 4 minutes to boot! Well I just tried booting without the SD card and it booted up in about 30 seconds! Does anyone know why? most of my apps are on the SD, I also have some music. But the SD is 16gb and a class 10 from SanDisk.
Any incite would be a great help.

Tmobile Galaxy Note sdcard issue

Just got my Tmo Note home, I think I got the last one as there were only 2 Denver retail stores that had them . Is there going to be a new forum here at xda for this phone?
I'm having an issue with the external sdcard, I am using ES File Explorer. I put the external sdcard from my old sensation into the new note, I browse to /sdcard/external_sd/ and I get an empty folder. Something reported to me that the ext sdcard was not mounted but I forget what I was doing when I saw that. What do I need to do to access the external sdcard taken from my Sensation?
I imagine this is an easy situation, I just haven't experienced a setup where there is an internal and external sdcard on a phone.
Thanks

That's interesting because I have a i717 and I flashed a nandroid backup courtesy of Rotohammer if I am not mistaken, when the device booted and I went to look for sd card it didn't show anything. But a reboot solved it for me. Worst case is you backup anything you need from the sd to a PC and fully format card.

I rebooted and still got an empty /external_sd folder. Once I backup the sd to pc, how do I mount/format the ext. sdcard?
Also, when I plugged the phone into pc with usb it shows phone as 9.85GB - I thought this came with 16GB of internal memory?
Under /mnt i have asec, obb, sdcard, secure and usb - no /mnt/ext_sdcard
Make sure the card if formated as FAT32 - if plugged into a computer, right click and select properties). I recently purchased a 64gb card and when I turned on the Note, I got the error the SD card was not mounted. I couldn't mount it or format it. Did some searching and others had that problem. The solution was to delete all partitions (searched cnet downloads for a partition manager) on the microSD card then insert into the Note & turn it on. The Note reported there was a damaged SD card - then I was given a prompt to format the microSD card.
So make sure your data is backed up 1st.
Not sure why your internal space shows that. That number seems low. May have to format internal storage and factory reset as it comes fresh out of the box.

I just got the T-Mobil Galaxy Note as well. I had not problem moving my SD card from My Touch 4g. At first I didn't understand the file structure, but now I see that the external cards shows under the directory of the SD card which really is internal memory. That memory shows only a total of 9.85 GB (should be 16 according to specs) and the other internal is 1.97 GB. I would also be curious if anyone know why the internal memory numbers are so far off.
My best guess is this.
11gb is parted off for user.
2gb is parted off for apps.
that's 13gb for user storage.
The rest is for /system, /cache, dalvic and future ROM updates. Naturally a new os will take more space so they make a best guess for future upgrades, features, etc.
You never really get what the advertised storage is. Plus its better to have more space remaining for the rom than what it actually needs to help future proof a bit and so you don't run into storage restrictions when upgrading or flashing custom stuff.
Take the xoom for example, it leaves 28gb for user, and only about 1gb to 1.3gb for the rest of the system. Because of that we have to use symbolic links to have some of the gapps load up when flashing as to avoid errors and such.
Sometimes having some missing storage is a good thing as its almost certainly belonging to the back end.
