Remove write protection from USB drive

One SanDisk Ultra USB 3.0 32GB drive decided it was time to be write protected. Diskpart showed that the disk was currently in a read-only state.

 

C:\WINDOWS\system32>diskpart

Microsoft DiskPart version 6.3.9600

Copyright (C) 1999-2013 Microsoft Corporation.
On computer: MEINCOMPUTER

DISKPART> list disk

  Disk ###  Status         Size     Free     Dyn  Gpt
  --------  -------------  -------  -------  ---  ---
  Disk 0    Online          111 GB      0 B
  Disk 1    Online          465 GB      0 B
  Disk 2    Online         1863 GB      0 B

  Disk 7    No Media           0 B      0 B
  Disk 8    No Media           0 B      0 B

DISKPART> select disk 4

Disk 4 is now the selected disk.

DISKPART> attributes disk
Current Read-only State : Yes
Read-only  : No
Boot Disk  : No
Pagefile Disk  : No
Hibernation File Disk  : No
Crashdump Disk  : No
Clustered Disk  : No

  

After a number of attempts suggested by Internet I decided that it was time to give up and give in to the dark side.

 

This was a FAQ entry at EMTEC: 

 

My flash drive doesn't work / My flash drive is write protected
HOME › FREQUENTLY ASKED QUESTIONS › USB FLASH DRIVES

You can try restoring flash drive by using that "Restore" tool (backup data before): Download link: http://www.emtec-international.com/sites/default/files/drivers/restore.zip If it doesn't fix the issue, flash drive should be returned to the store where it has been purchased to get a replacement. Process to restore: 1) Plug the flash drive (certify that only the EMTEC flash drive is plugged) 2) launch restore.exe 3) Press the button RESTORE 4) A warning message is displayed about erasing data. Press RESTORE to continue. 5) A confirmation message is displayed, then press the YES 6) A message RESTORING DEVICE ... appears. Do not unplug the flash drive and wait for the restoration (1 to 2 minutes).

The download link is also dead but I found a program that fit the description. Ignoring the "certify" part and following the instructions I now have a working SanDisk USB drive. An empty one but at least I can use it to unimportant file transfers.

 

This is a copy of the program. Use at your own risk...

I will never buy a SanDisk USB drive again.

You are aware that this could happen to any flash drive regardless of manufacturer, right? Smiley Frustrated

Yes. I will try and see if they grant me RMA of a "currently" working drive that is without a proof of purchase.-) I am trying to get it to fail again using "H2testw" endless write/verify.

 

This is not the first time a SanDisk drive has given me problem. It has been drives that have identified themself as "Local Disk" instead of the expected "Removable Disk" which created a lot of problem with programs that apperantly only works with a "Removable Disk". Drives that suddenly stopped working in any USB input on one computer but continued to work in other computer. Drives that sometime didn't work in a certain USB port when every other USB drive always worked.

 

All of this I have never seen from any other "brand" USB drive. No more SanDisk for me

Re: Remove write protection from USB drive

I have had the same issue and sent it off for a replacement.

 

Why are SanDisk USB drives setup with this unremovable write protection? not very user friendly is it.

It beats the other option, of dying and everything being lost.
