Removing write-protection from a flash drive.

I have a problem. I was error-checking my USB flash drive when my computer froze and had to be hard-rebooted. This locked said flash drive into write-protected mode. Everything is still accessable, with the exception of the files it was checking when the computer froze (which I don't care about).

Being that the drive itself is write-protected, I can read and copy off of the drive, but can not change anything or add anything. I can not remove the write-protection. I can not reformat or even disk check it again. Relabeling the drive does not help, nor does trying to change file attributes through command prompt. There is not a switch on the side.

I am using a Corsair Survivor 32GB flash drive. I have tried fixing it on Windows XP and 7.

The drive itself is write-protected, not just the files. All efforts to bypass and/or remove it have failed. I'm content with formatting it and starting over, but it won't let me. Below is what I have tried after the basics in Windows itself failed.

The type of the file system is FAT32.

I don't have a "transcript," but using the command string "attrib/d /s "e:[anything I used]" -r" and any other variations failed as well. It basically said that it wasn't interested in working with a write-protected directory.

I don't think the drive is write-protected.

Just that partition that was being chkdskd. So go into your OS'es Disk Management, delete the partition from the stick and create a new empty one. Does that work?

More from Command Prompt

E:\>attrib/d /s -r
results in pop-up window:
"The disk cannot be written to because it is write protected. Please remove the write protection from the volume CORSAIR in drive E:"

Kees_B, thank you. I will go try it and see what happens.

Nope. Not it.

I went into the disk management console. The drive is only one partition, so deleting one isn't an option. Neither is adding one, that I saw. I tried formatting it again (for kicks) and was told "The operation did not complete because the media is write-protected." I have also tried disabling then re-enabling the device doesn't help.

Little more

To clarify about the partition thing not being an option, right-clicking the drive in the disk management had the option for deleting a partition, but it was shaded dark and wasn't clickable. I wasn't just assuming that it wouldn't work based on the presence of only one partition.

More power.

If this was mine I might boot up GPARTED and see if it can remove that USB partition and create a new one.

I might also try the HP USB FORMATTING UTILITY and format it with that.

I downloaded it, burned it to a disk, and attempted to boot with it. It skipped it and went straight to windows. I noticed a lot of files were labeled linux. Is this the wrong version?

It's a Linux CD, so that's quite OK. Two questions:
- Did you burn it as an iso? Some burn it as data and then it doesn't work.
- Did you check that your BIOS is set to boot from the CD-drive? If not, it boots from the hard disk whatever CD you put in.

All of this is a lot of work to save a USB-stick. If no luck with GPARTED, it's best to throw it away, I think.

I was wrong

I burned it wrong. I don't know that I have the option with my little burning program to do it correctly.

As far as the amount of work involved, I'm deployed in Afghanistan. I don't have anywhere to buy a new one, and I honestly don't have anything better to do with my free time anyway. I still have an external hard drive, but I like having backups for the backups.

Tip: Look up IMGBURN

It's a better tool for making a CD/DVD from the .ISO in my opinion.

But try the HP USB FORMATTING UTILITY first (see google)

Did you burn it as an .ISO?

Some file put the .iso file on the CD and wonder why it won't boot. Tell me what you see on the CD. If you see the .ISO file, then you didn't create the CD properly.

same drive, same problem

I was wondering if you got any further yet. I have the same drive and the same problem, got stuck with the same error messages under XP, win7 and under cmd-prompt. I also tried an extra registry entry to set write protection to null. No success. I just sent a request to corsair and will see what comes of it.
Please post if you got any further towards a solution please.
