WTF...SD card Damaged, but IS AVAILABLE via pc - Android Software/Hacking General [Developers Only]

Odd issue....Running Smoked Glass and everythings been smooth as hell. then out of no where my SD card isn't available. YES, I have rebooted, popped out and in, same with battery. All no help. I get the "SD card is Damaged" and obviously not usable.
HOWEVER!!!
When tethered to pc and mounted...all the SD cards data is there on my pc. Unmount and the card is suddenly "damaged" again....so WTF?????
Yes things are backed up, but I want to figure this out to insure it doesn't happen again and to aid others.
Any clues?
Thanks........

This happened to me a couple of days back. It happens when your phone is tethered to the PC and the SD card is mounted and then you just unplug the phone while the PC still tries to write something to the SD card.
Try to put the card into the card reader, go to My computer->right click on the SD's drive->Properties->Tools->Error-checking->Check now, and let the program check for errors. I haven't tried this, so it might not work.
If it doesn't work, then do what I did: make a backup of everything, format the card, error-check it again, and copy everything back (this is also a great opportunity for a little "spring cleaning" of the SD card ).
And remember to always use the "Safely remove" feature on your PC.

There is also a thing on your phone in which you can have it unmount the SD card. Always do that when you're taking your phone off. I know it seems tedious, but thats why you're not supposed to just unplug your computer or yank a flash drive out.

try to use this formatter ,hope it help .

SD Card Damaged. You May have to reformat it... There MUST be a solution

On my MyTouch 3g, if my phone shuts down or reboots unexpectedly, many times my SD Card will not mount. There MUST be a solution for this.
In recovery, I can see my files, so I know everything is not lost. How can I get Android to recognize it again?
I've researched hours on this. Formatting works, but I lose my info. There has to be a way to restore whatever files are getting corrupted from unexpected shutdown.
Windows often does not see it, ONLY in recover. So if, linux can see the files, it should be able to be repaired. How can I do it?
Move all of the files to your computer, format the card, then restore all the files?
Nope... too easy. I need a way to get the card o recognize again. There has to be a way....
I was told by a Sprint rep that phones are generally pickier about recognizing and reading SD cards than computers are. I had asked him to check out my SD card because my phone kept having problems mounting it, and he said it didn't matter if they checked it, it would always look fine if plugged into a computer, and ended up giving me another SD card for free.
Hope this helps.

Corrupted MicroSD Card - Apps2SD

I have this problem that keeps repeating itself.
I have been using the latest BiffMod Rom for a few weeks, all has been fine until I moved some apps to the MicroSD card via the inbuilt application manager.
The phone works fine for a while and then one day, nothing. the phone doesnt want to boot or anything. After some investigating it turns out its the MicroSD card that is corrupt.
If remove it from the phone, the phone operates as expected, If I insert it, I either get freezing, or the safely remove SD card message. The card wont mount.
I have tried the card in a Windows PC and it will read the Fat32 but freezes after a while.
Now this is not the first time this has happened and the pattern is emerging that it seems to be when ever I move apps to the SD.
Has anyone else had similar problems, I have gone through 3 of the same card in about as many months, luckily I have a bunch of cards from work. But its super annoying.
completely The card ends up been completly useless.

Well, for one, Biffmod moves apps2sd automatically, using scripts and when you do it manually, you are messing with the mod. So, thats where you messed up.
Secondly, I too messed up a 16GB Class10 SD card but, was able to fix it by reformatting it in ubuntu then again in Amon_RA recovery menu. I originally had it formatted 1024MB ext4/96MB swap...when I re-parted it, I had to change the sizes for it to work. Now, its 512MB ext4/32MB swap.
Third, a guy (MrBurrito) gave me this script file he made to try and fix the card. You copy it to your sd card, flash it in recovery, wait 10-20 seconds after it finishes and, then reboot. It didn't work for me but, I'll attach it, maybe it can work for you.

[Q] ACER LIQUID E - 16gb card "checking for errors".....

Hey all.
FIrst off I dont recommend this phone. haha, that being said...
I just bought a 16gb microsd card for it. I was able to install it and transfer a bunch of tunes over. Then when I disconnected it from the computer, it has a little sd card icon with a sprocket at the top left of the screen and says "checking for errors". As a result, I dont have access to the info on the sd card > music contacts photos etc.
Its been 12 hours or so and this status has not changed.
Can anyone shed any light on this issue? Has it "farted" or do I just have to wait...
Thanks.
Have you tryed turning the device off taking the battery and SD card out then putting it all back and turning it back on, had issues with my phone not recognizing my SD before and it worked for me, just give it a try and see.

Thanks, but tried that many times...
I did try removing the battery and card multiple times to no avail.
I even sacrificed my programs etc through a hard reset. As soon as the reset completed, I have the same notification about the sd card.
Some details...
When I first inserted the 16gb SDHC card, the phone acknowledge its presence and I formated the card in the phone. It said there was over 15gb available... all fine...
I then was able to que it up with my pc through the USB cable and transfer about 8 gbs of music to the phone... transfer when fine.
Upon removing the phonne, it started with this "preparing sd card, Checking for errors" nonsense.
I am firmly convinced that there ACTUALLY is no SDHC support on these Acer Liquid E phones. My old 2 gb card that came with the phone works just fine and is back in the phone now. My only other option is to buy a 4 gb card and see if that will word fine, as 4 gb is not considered SDHC. then step up again to a 8 gb card (SDHC) and see what happens.
Does anyone else have a SDHC card in there Acer Liquid E? Does it work?
There is also NO help from Fido or Acer to work through issues...
Really makes me want to go back to the iPhone........ grrrrrrrrr....
Make sure that you formatted it to FAT32 first of all and does the card still connect to the computer using a card reader ? Why don't you try formatting it on your liquid by going onto storage and then unmounting it then format.

Thanks... no go though. At wits end...
Thanks for your attention!
When formatting in the phone, it doesnt allow you the choice to format specifically in FAT32 or other. I can only assume it is formatting in the proper system.
As for mounting and unmounting (what I feel this phone has been literally doing to me for the 6 months i've had it.lol)... as the sd card was stuck in this "checking for errors" sequence I had no access to mount or unmount the card or reformat again. These options were simply greyed out and not accessable.
I have not placed it into a card reader to reformat through my PC. I will try this step next and see what happens. I will have to find a card reader, or perhaps plug it into my camera as the card came with an sd adapter... see if that route will work.
Regardless. extremely user non-friendly phone here in the Acer Liquid E.

External sd card no longer visible

I need assistance to restore the external sd card on my Galaxy Tab plus. For some reason My Files began crashing on start-up. I then discovered that the extStorage link was no longer available in any explorer. When I open the settings menu and click Storage it force closes as well. I tried a Factory reset to no avail. I located a new Myfiles.apk on line, but it wont install.
Please, if anyone has any ideas short of flashing the rom, let me know.
Now I'm kind of a noob in regards to tablets, but if it was me, I would turn off the tablet completely and then remove the microSD card. I would then turn on the tablet and make it is functioning properly. If so and if I had one, I would plop in a different microSD card and see what that does.
If that is all working, then suspicion falls on the original microSD card. I would then put the microSD card in a SD or USB adapter and insert that into, again if you have one, a laptop or desktop computer. If it does, see if you can copy the files over to the computer and then use the computer to refomat the card to "Fat 32".
I would then take the card out and plop it back into the tablet and if everything is working.
If so, dismount it from the tablet, insert it back into the computer, copy your files over and then plop it back into the tablet and see if it now reads your files properly.
This is kinda like a crime scene, you need to do small discrete tests to see where the problem lies. Is the culprit your tablet or the tablet card port or the microSD card or a corrupt file on the card or was it Colonel Mustard with a knife in the parlour closet...
G.B.
And remember, talking dogs are liars.
Been there, done that.
Ja, I have tried that approach. It seems this criminal is a tad more sinister. I think my only option now is to flash the stock rom. I was hoping to do that when ICS came out though.
Thanks for the help!

Obnoxious Problem with SDXC Card - Card on Computer Works Fine, Phone Wants to Format

Card is a Sandisk 128GB Ultra MicroSDXC A1 card.
Card is formatted exFAT.
Card can be mounted, opened, and read/write with no problems via my laptop when plugged directly (SD slot).
Android (LG G5, LineageOS 15.1) says card is corrupt, is trying to make me format. Card initially set up as "Portable Storage".
Took FOREVER to move music onto this card, as artists had to be moved one at a time or transfers would fail, so I'm trying to avoid formatting.
I've tried rebooting the phone, repairing the file system using TWRP Wipe command (fails with error code 1), and mounting with a clean eject via Windows 10 on my laptop using the SD card slot. Nothing has made an impact, stupid phone still won't allow me to use the card.
If anyone has any ideas why this is happening, or how I could potentially fix this without having to wipe the card, I would appreciate it. This thing has been a PITA since I got it, I thought it would be awesome having such expandable storage on my phone (I'm a weirdo who doesn't use streaming services) but I've had nothing but problems so far. I have to be careful with how I transfer files onto the card or the transfer will take an (appropriately) long time, act like it works, but then the file just won't be there. Now I've finally gotten the card loaded up, and after a routine phone reboot a few days ago, the Android OS is trying to say it's corrupt; This is also making me worry that this will continue being an issue in the future.
Running "chkdsk E: /r" on my laptop is revealing a couple minor corruptions inside the directory, and volume bitmap. It's hanging on verification/completing now.
Is it possible that I have a bad SD card? This thing has seriously done nothing but suck since I've been trying to use it.
Edit: Unless someone tells me otherwise, I'm pretty sure this is a bogus/defective SD card. I simply cannot believe that flash memory would perform this badly. I'm going to return this card (bit of a PITA since I ordered it online) and buy another one locally.
