External Harddrive space not freeing up even after deleting

by meme427 - 10/9/07 9:05 AM

I have a 2.5" External hard drive that has a lot of data on it
I was trying to free up some space on the hard Drive but when i delete anything the space does not come. I deleted a 4.5 GB folder and the free space still remained 687MB.
I do this with any files on this hard Drive the space does not increase.

I have tried to defragment my drive, done disk cleanup.
I have obviously emptied my recycle bin (besides i did say this is an external drive)

Anyone got a solution?
