Disk Management shows the total space on the drive even when it has no data on it at all.

If Disk Management shows that the total space on the flash drive as 120mb, it IS 120mb..
Either it's FAKE 2 gb drive, or the drive's circuits are damaged.

Neither problem can be fixed.

You can verify speed, and capacity(ie fake/counterfit) with this freeware tool, found here: http://www.softpedia.com/get/System...

So, you are saying that you downloaded the test software I linked you too, ran it, and the flash drive is not a counterfeit. In essence sold as a 2gb, but not really one. Did it pass the test and show up as a true 2gb.

Look at it in Disk Mangement.
E.g. Type: diskmgmt.msc in the Start Search box, press Enter.

If that shows that the total space on the flash drive is ~ 2 gb or ~ 2,048 mb (it will likely be a little less than that), then data for the software file system on the drive has been damaged. There are programs that you can use to fix that problem.

See response 2 regarding how you use Safely Remove Hardware:

........

When you delete a partition and make a new one in Windows 2000 and up, you are
- organizing it using a software file system - FAT, FAT32, or NTFS
- and then that organized file system is formatted.

By default, you cannot delete the software partition on a flash drive in Windows and make a new one. You can only format it. If the partition's file system data is damaged such that the full capacity is not seen, then only that capacity will be formatted.
.......

Manufacturers specify the size of a flash drive, or memory card, or hard drive as a bogus decimal size, e.g. 1 gb = 1.000,000,000 bytes. The operating system and most mboard bioses see the size as it's binary size. e.g. 1 gb = 1,073,741,824 bytes.

If the flash drive is exactly 2.0 gb - manufacturer's size (the actual size varies) that's = 1.863 gb binary size, and a small percentage of that is used for the file system and formatting.

"Disk Management shows the total space on the drive even when it has no data on it at all. "

....as in, when you scroll down in Disk Management, the total space on the drive is shown on the left beside the rectangular box on the right..
