8Gb Flash drive only showing 465MB Avail.

[capttripppp]

What can I use to fix this or wipe the whole flash drive so I can have access to the whole thing?

Format the drive. Your OS should have a format option in there somewhere.

I have formatted it, more than once and I am still having the same problem. Very strange if you ask me

You sure it's a real 8GB drive?

[capttripppp]

Positive, it's an 8gb sandisk cruzer. Never had any problems with it until yesterday when I plugged it in

I've had something similar happen to me. Try these instructions:

1) Type "DISKPART" from the Command Prompt (accessible by clicking on Start and then typing "cmd" into the open field); you will then see the following prompt: DISKPART>
2) Type "LIST DISK" to see what number your USB drive is listed as.
3) Type "SELECT DISK 2" (if your USB is disk 2; replace # with your disk #); Diskpart will confirm that "Disk 2 is now the select disk."
4) Type "SELECT PARTITION 1" (this command selects what should be the only partition on your USB drive, the small one that you want to delete to get back the larger, full partition size). Diskpart will confirm with "Partition 1 is now the selected partition."
5) Type "DELETE PARTITION". This will delete the old partition. There are no warning prompts if you have existing data - make sure you have copied everything off before doing this!
6) Type "CREATE PARTITION PRIMARY" to create a new, full-size partition. Diskpart will confirm with message of "Diskpart succeeded in creating the specified partition." You can type in "LIST PARTITION" to confirm the new, full-size.
Wouldn't CREATE for me, so i used the CLEAN option, then Retried #6 and it worked like magic.

7) Type "EXIT" to leave Diskpart. You can now format your USB drive by using the standard Windows formatting process.

*edit: actually post #8 (http://www.bleepingcomputer.com/forums/topic219693.html/page__view__findpost__p__2385981) had a proper solution it appears. I don't have a USB drive here at work otherwise I would try it to verify that it works. I've edited the quoted area above to include the instructions from post #8.

If you have problem with diskpart, you might try this.

Ah Hah, success. Which method worked? The mini-app or the Diskpart method. I am wanting to know for my own future use since I have heard of non-fake Usb sticks doing what yours did. Thank you.

The disc part method worked for me. I had to "clean" it after deleting the partition. But it worked well Thanks Bent

Good to know and thanks for the shout back. I will keep the diskpart method saved in Text file. RGone...ster.

No problem. Glad I could help :thup: Took me a while to figure out the solution myself when I was having the same issue.

I tried googling the heck out of it yesterday to no real end. I tried a few ways that I found, but none of them worked
