Hard drive problem?

[mikhailmetatron]

One of my internal hdds has a weird problem and was wondering if anyone has had similar problems and/or know of a way to fix. Basically the hdd in question is for storage and when i use CUT and then PASTE within the same drive, it COPIES instead. Meaning i have to manually delete the original copy after the transfer has completed. This problem is only experienced on this particular drive as the CUT and PASTE functions work fine on other hdds w/o having to manually delete the original. I tried using programs like Teracopy to see if it would help, but same thing happens. Also when using Teracopy, under the SOURCE column it says "Cannot delete source file" after it finishes the transfer. And again would have to manually delete the source file. Any help would be appreciated.
