Well, if your old drive already wrote corrupted data, and now the 716 does as well, then it’s really obvious that something is wrong with your system, not with your 716.
If you had to underclock to get the system stable, there is something terribly wrong!!
Writing to the same location is difficult as the drive chooses were to write on the platter although the path might be the same.
Nooo, I did not mean exactly to the same location. I only meant to the same hard disc or perhaps partition.
I suggested that because I several times had trouble with data corruption when I only copied data from one hard disc to another. :Z It was an incompatibility between my PCI RAID controller and the mainboard’s BIOS.
The wierd part is that all the discs I’ve written too without making an ISO file is fine.
I think you haven’t yet mentioned which software you are using to create those ISO images? Because I guess that this particular software could be the reason for your trouble.
