Hi.
I have an external hard disk LaCie d2 Quadra 1To that I use to backup my computer. Since 2 days I can't access data on it. I can see the drive with device manager and disk manager win 7, but when I use explorer it generates and I/O error. On disk manager the disk has the good size but the partition is Unallocated" and "raw". I used the tool HDD Raw Copy Tool 1.10 and the log is:
