SOLVED Convert FAT to NTFS

[Nikilet]

I purchased a 16 GB USB drive to use as ReadyBoost. In reading I discovered that NTFS is best because you can use more of the space and that you can convert FAT32 to NFTS.

I had already devoted the drive to ReadyBoost before I tried this so maybe that is my problem.

Anyway, I followed the instructions to convert to NTFS and I get this message:
C:\WINDOWS\system32>convert H: /FS:NTFS /X
The type of the file system is FAT32.
Convert failed to dismount the volume.
Convert cannot gain exclusive access to the H: drive,
so it cannot convert it now. Would you like to
schedule it to be converted the next time the
system restarts (Y/N)?

So I typed Y and then I restarted. After restart I opened command prompt as administrator and again tried to convert with the command and I got the same messsage again.

Can anyone help?
