One of the four internal harddrives (SATA) of my computer is causing me some trouble.
This drive only have one NTFS partition. Everytime I try to copy a file on it, the copy eventually fails after a few seconds, and the disk completely disappear from my OS (Win 7).
Even if I take a look at the Disk Management tool (in Computer Management window), the drive isn't there. The only way to make the drive reappear is to restart the computer.
I did an error check, and nothing came up. This drive worked fine in this configuration for at least a year before starting to do this.
Any idea on what could cause the problem, or on what I should be looking for?
