I formatted a cruzer 8gb flash drive. Now i only have 4 gb. How do i get back to a full 8 gb avail?.

instead of deleting the files its better you format the pen drive. Formatting can be done by > my computer-> right click on pen drive> format >start.

Click on round windows button (on the bottom right) > right click on "computer" > manage > select disk management > if you can see the flash drive in on the right hand side right click on it > format.

have you tried to reformat the flash drive?
go to my computer right click on your 8GB USB drive and select format, this should give you a real clean start.

You need to format it as NTFS because FAT32 (your current flash drive file system) doesn't support files bigger than 1GB.

Try doing a full format of the drive. (Right-click on drive => Click format).

If you have the option format using the NTFS file system (default in vista/windows 7) and make sure to uncheck "Quick Format". Remember to back-up your data on the drive beforehand.

If this doesn't solve your problem the flashdrive itself may be faulty. Return it and have it replaced.

Hope this helps,

Have you tried a virus scan. if not try that, if the problem still appears, boot your pc in safe mode, and format vai that route.

1. right click on my computer then manage
2. click on disk management then right click on the drive which you want to format then click format it will forcely format your card.

copy the files to you're pc, and if you use windows just go in my computer and right click on the flash disk icon and click format check the quick format box and the press format.

Fat32 File system is limited to just under 4 GB. I've tried to format using a different file system but no success.

This isn't really a solution but at least it explains what's happening.

There might be a hidden file(s) on the drive that are taking up that space. Open the drive in My Computer, click Tools > Folder Options... On the View tab, click Show hidden files and folders. Then check the drive to see if any hidden files or folders are present.

You can also try formatting the drive. Right click the drive in My Computer and click Format...
