[Q] Erase data from bad microSD card? - General Questions and Answers

Hi,
I have a 32GB microSD card that some how got corrupted transferring files between my Windows 7 PC and my Asus TF300 Android tablet. Fortunately, it is a SanDisk card and they are willing to replace it for me, but there was personal information on that card and I would rather they not try to recover the files on that card or even have access to them.
As far as I can tell, the on-board controller is bad, but all of the actual data is still just sitting there on the card. So far, I haven't been able to access the files or format the card with Windows, Linux, or Android, both in a microSD slot on a tablet/phone or in a card reader with an SD adapter. Most of the time, the device won't even recognize it as a valid SD card and when it does, I get an I/O error. Windows "Format" tells me that it has an "unknown size" and can't do anything with it.
Most of the information I have found tells me what to do with corrupt files, but not a corrupt card. Does anyone know of either a way to recover the card or any way to erase the data without having access to the card itself?
Thanks,
Don

sd card

How to i see my sd card on my computer so i can put things onto it? Im rooted and have cmw
It's under "removable" and you will see "microsd." Also, if you end up not being able to mount it, make a partition on your uSD card and that will probably solve the problem..
only thing to show up is the the internal storage. How do i creat a partition?
Ok i found the sd card. Its under device storage. It wont let me put anything on it though
All im wanting to do is put a custom rom on my sd card so i can flash it.
Make sure that your SD card is formatted in a way that your computer can read it. For best compatibility, format it as FAT32. You'll probably need to plug it into a computer in order to do this, which probably defeats the point in trying to do this using the device as a huge SD card reader.
Also, if your card -is not- the microSD card, make sure that it is not ticked to the 'lock' direction. On normal sized SD cards, there is a moveable nub.
Check to see if you can write files to the SD card FROM the Transformer. If you can, the alternative is to download the rom file to your Transformer, and then put it on the SD card from there.
Bumping your thread/making multiple subsequent posts won't make it so that you receive assistance quicker. If anything, it will make people ignore you because You are a Noob. You hate yourself(azrienoch, YouTube, 2011).
i can see it fine on the transformer. Could it be something wrong with cmw. How do i reformat it.
Plug your SD card into the computer, and use your disk management software that ships with your computer. If you're on Mac OS X, use Disk Utility. If you're on Linux, use cfdisk or fdisk.
On my machine(windows xp), if in windows explorer I click on
Transformer TF101 - Portable Media Player,
I get two different options
Internal Storage or Micro SD
This was after an update to the ASUS sync software though.
Originally I could only see the MicroSD was through
Internal Storage->MicroSD
When accessed through the tranformer, this is not writable. This is a limitation of sd cards. You can't have two hosts with write access.
The other way is to put it in internal storage, then use the transformer's File manager and copy from the SDcard, and move it to /Removable/MicroSD
Ok the sync program i downloaded is not in english. Its the one fromthewebsite too
Can you clarify if it is a SDCard(in the dock), or a microSD card(in the tablet)?
You can't see the dock storage from a pc, I believe. I also think you can't install roms from the dock.
Sorry i probably didnt know what the dock meant then.
It is in my tablet. I plug it into the computer. If i go to computer and look at it it says. Asus Transformer tf101. Click on it again and it says device storage and thats it. Its like it cant see my sd card at all. Is there a way to go into usb mode or something so my pc can see it? Also on my sd card all it says is lost. something. Shouldnt there be more since i rooted it. I got su functions
I think that you should be able to see it through internal storage, either Removable folder, or microsd folder.
If not, just copy it to the internal memory, and cut/paste it through the transformer file manager

Micro SD card unreadable after trying to format it

Today i was attempting to partion my SD card so i can install more applications on my phone(i hate the low internal memory i have). Anyhow, i used this tutorial to get it done, and now my SD card wont be recgonized by either my pc or phone, i tried booting into recovery in my phone and partion it trough recovery, all i got was "Mounting of SD card failed!". On Pc it actually picks up that thre is an SD card inserted, but wont read it.
I realize that i need to format it, but there is no option to do so on PC, or at least i cant find it, im guessing a special programm might be needed.
Any ideas?

[Q] Help with SD cards

Hey everyone! I have problems with multiple micro sd cards.
I have an 8gb micro-sd card that will not read anywhere at all. The computer won't even recognize it as a device. My phone will say that it is unsupported, and cameras do not recognize it.
I also have a 64gb micro-sd card. The problem with this one is that it is recognized, but not able to be formatted. my phone and computer can not format it. And a camera says that it is too full to take pictures, but that there is not a single file on it.
Any ideas on what to do about any of this? Any help? or just any useful thoughts?
You may want to try the HP USB Disk Storage Format Tool.
With it I've been able to delete partitions that I messed up in linux.
If that still doesn't work you could try a linux livecd with gparted on it.

Recovering an "Adopted" SD Card?

Hi folks,
I have an SD card here that I was using for Adopted Storage but I've managed to get it stuck as an "adopted" card and can't seem to get it back functioning as a normal SD card
Long story short... I wiped the device the card was in but I didn't "unadopt" the SD card before hand - as in set it back to portable mode. While the device could recognise there was an SD card afterwards, it couldn't prepare it for use and suggested a card error or something to that effect.
I figured I'd just pop it in my laptop (Windows 10 x64) and re-format it but this didn't work. Failing this, I decided I'd "nuke" it using Minitools Partition Wizard. While this program had better luck identifying the card, could display and delete the partitions on it and could run the Wipe task - it had no effect on the card... the partitions just re-appear after any attempt to nuke them!
Has anyone any ideas about how I can restore this card back to a normal FAT formated SD card?
Just to clarify - I don't care for the data that might be on it... I just want the card back usable
Thanks
Recovering an "Adopted" SD Card?
The best solution for now would be to plug the sd card into a phone with android 6.0 so that the phone can read the card and then while setting it up,you can format the card as "normal "(the part where it asks you whether to use the card as in adaptive storage or for accessing files).

When I try this, I get "Unsupported SanDisk SD card"
I'm then asked to select either Portable or Internal and then Erase & Format but neither work. They fail at 20% and the message "Unsupported SanDisk SD card" is shown again
I'm a bit stumped. I thought surely the encryption used on adopted cards was only to stop external reads. It seems in this case it's stopping me from writing to or formating the card

Please Help Recover Data on Corrupted Adoptable SD Card!

My SD card is set as adoptable storage, but it has gotten corrupted. It happened when I was copying files from my phone to PC via USB (ironically I was doing this to backup my files from my phone). Somewhere during copying, the phone virtually disconnected from the PC, and on my phone it said that it couldn't read my SD card.
Couple of things to note:
I'm using Lineage OS.
The SD card isn't encrypted.
When connecting the SD card directly to my PC, the SD card shows as two drives, D: and E:, with D: being accessible showing an almost empty drive of 29,4 GB (which is the full logical capacity of this drive), and E: inaccessible, requiring a reformat (no idea what E: is). On D: the folders that I can see are .android_secure, Android (with the sub folders data and media) and LOST.DIR. All folders are empty.
This SD card should be filled with data almost up to max capacity.
I haven't changed a thing to the corrupted SD card. I did not reformat, used CHKDSK or w/e. The only things that I have done is attempting to make raw copies with HDD Raw Copy Tool and R-Studio.
I've read here and there that it is (almost?) impossible to logically fix a corrupted adoptable storage SD card in that I could just pop it back into my phone to resume where I exactly left off. So I'm looking to recover as much data from the SD card as possible. I'm most concerned about recovering my Whatsapp folder (I haven't got a complete GDrive backup of this), but I'd prefer to recover everything else as well.
What must I do?
