Doubt, it is possible to change the position of disk and hard disk to detect in bios but usually does not identify the unit. Got a hard disk to another laboratory my client did not accept the budget and brought me to attempt to recover your data suspect that the dishes have been exchanged in position recognizes the hard disk normally.

HARD DISK SANSUNG
MODEL: HD160JJ 160GB

If the disk was opened, tampered or dropped - or weak head, these are the symptoms. Excluding media damage I can 100% fix Samsung drives. It is also possible to fix alignment problem. If you want to outsource send a PM.

I suspect that the disks were swapped position of the hard disk was bad only in the PCB, the other company may have put the disc from the bottom up and from top to bottom so I know whether this change influences the recognition of the hard disk by Bios

If you're right and If they haven't degaussed the platter(s) or put other disk platters on your drive, is data worth about 2000 eur + taxes?
