I have a Micro SD card inside a USB 2.0 adapter that is not working. I have tried a few different methods to fix my flash drive with no results. The micro SD card is 32 GB inserted into a USB 2.0 adapter.
- When I plug the drive into a port, Windows 7 makes a sound, and I am prompted to format the drive. I failed after a number attempts to format the drive. I tried all the ports on three different computers (same results).
- Next, I uninstalled the USB driver and reinstalled the flash drive FAILED
- I opened CMD, entered
diskpart>select disk 1>cleanand I followed more steps that I found online but still FAILED - I changed the LETTER of the drive, then continued the step above FAILED
- I tried to insert the drive into my Xbox 360 to try to format it FAILED
- I tried four different recovery programs FAILED
- I tried to format each sector (it took 3 hours) FAILED
- I removed the card from the adapter and placed it into an SD card, then inserted it into my laptop FAILED
- I tired using a micro USB adapter to connect to my cell phone to erase ALL on the drive FAILED
- I tried to use ERASER software to delete all on the drive FAILED
The drive was working fine two days ago. It was used to store video games and add-ons on my Xbox 360 console. Two days ago, I went to play a game on the drive, but it wasn't there. In fact, the console read the drive was almost full; however, the contents was empty.
I would like to delete, erase or reset the drive so I can use it again. I don't need to recover its contents; I can always re-download the games and stuff.
What can I do?

I would suggest to check your USB adapter for a write protect switch however you say putting just the microSD in your phone still fails so I do not see that being the cause. The most likely culprit is the flash memory is worn out and will not function anymore, however I have had success in the past by using ChkFlsh to recover both an SD card and a USB flash drive that would fail to format.
- Download and right click run-as-administrator ChkFlsh from the link above (the download button is the small text above the picture of the program).
- Click "As physical device (NT-based systems only)", select your drive from the dropdown list, then scroll down slightly and select "Low level initialization."
- VERIFY YOU SELECTED THE CORRECT DRIVE! This tool can and will wipe whatever device you point it at.
- Click Start. Click Yes on any warning that comes up (there's a couple different ones depending on what it sees on the drive.)
- Next a window titled "Partitions" will open up, select partition 0 and click New, on that window that pops up just click OK. (Even if it selects a filesystem you don't like, just use Windows later to reformat it to what you want.)
- Click Yes to write all changes to disk and when asked replug the device without unmounting/safely removing it.
If, and that's a big if, your microSD card is repairable this will have done it and you should have a formatted empty microSD card. If it still doesn't work it can function as a table drink coaster for a tiny mouse family, or just toss it in the trash.
