Hello,

Have you tried reformatting it? Does that USB key show up as 1GB in other computers?

if youve tried reformatting it and it doesnt return it to its original size, some of the memory could of gone bad. Ive had this happen to a usb stick before.

Do you mean the you installed linux on the USB drive? if so the installation will have created some linux paritions (usually ext2,3 or 4) and maybe a swap parition.

You will need to repartition the drive if this is what happened.

Most likely it is just a partitioning problem.
First try using windows Disk manager to show partitions and to delete/repartition and reformat the usb drive.

Unfortanutly this may not work and you will need
A) a third partitioning disk utility, or
B) What I use. use windows cmd line diskpart cmd to remove it (what I had to do for a thumbdrive used on a Mac)
.. If diskpart is what you want to use, be cautious and make SURE it is pointing to the USB drive.
Basically (read this first):
http://technet.microsoft.com/en-us/library/cc766465(v=ws.10).aspx

.. You open a dos command window WITH run with admistrator privlage. then type the following cmds.
- Diskpart Starts program Do Not type the - (ie diskpart> List disk then enter key)
- LIST DISK (shows all disk, look for Disk Number of the Drive (Your USB drive)
- SELECT DISK X (For X insert USB drive Number)
- DETAIL DISK (Detailed information of the disk that has the focus This will show if you have selected the correct drive.)
- CLEAN (One of the most practical and most dangerous: it removes at once all the partitions on the selected disk.)
Note for the next two do NOT use the size=n)
- CREATE PARTITION EXTENDED (Creates an extended partition on the current drive. After the partition has been created, the focus automatically shifts to the new partition.)
- CREATE PARTITION LOGICAL (Creates a logical drive in the extended partition. After the partition has been created, the focus automatically shifts to the new logical drive.)
- EXIT (Quits DISKPART and returns to the command prompt classic)

You should now be able to format the drive (WITH the correct space) using windows

I tried to do this but it wouldn't allow me to create a logical partition. It said "The operation is not supported on a non-empty removable disk." Even though I had "cleaned" it like you suggested.

Try this after "Clean" command:
- create partition primary
- select partition 1
- active
- format fs=ntfs quick
- assign

Change "ntfs" to "fat32" or "fat" if you rather use them.

To make it simpler, Just start Diskpart, select disk and then put just clean. then go to computer management > Right click on drive > New simple volume > follow the steps to format. Then you have to wait. It usually takes a long time to format the USB back

there are very few stebs all those are just making it so difficult flow these steps:-
1)go to start
2)type"cmd"

That wont work. The partition has to be logical in order for windows to use the flash drive properly.

My drive is a Verbatim Tuff n Tiny. I had 7.45 Gb (8 Gb), but suddenly I plugged the drive into other computer and I got a message saying that I had to format the drive in order to access, all my information was gone, but then I was limited to just 4 MB. I tried everything: Bootice, HDD Regenerator, HDD Low Level Format, HP USB Disk Storage Format... but nothing helped me.
Then I tried installing the secure software V-Safe100.exe which comes with the Tiny n Tuf USB drives, I downloaded it from the official website. And I tried to unlock the secured space. Voila! it worked, then I had to format with HDD Low Level Format. I just got 7.45 Gb and then format.
I had another issue, my drive was write protected. But after some tries, I find out a program called Program & Restore, I used the restore option and wait. It worked perfectly. Now I can storage lots of files.
During my research, I found a program called SDATA Tool, that enables your USB double its space, worked for me, formating my drive before trying it to NTFS, I got about 11 Gb. But the storage capability goes away if you format again the drive.

So in conclusion, I had just 4 Mb and ironically end up with 11 Gb. Also, if you plan to storage big files (one file of 5Gb for example) you have to format the drive as NTFS, else you are going to get an error due the FAT or FAT32 filesystem cannot storage files that big.

Hope It helped.
