yes. but this shouldn't be a reason for the drive to be recognised as a 60Mb HDD. should be?

Failing / failed heads can do this.

This may be an ignorant question, by why does the report say the following?

Device information:
WDC WD10EADS-11M2B1
Serial number: WD-WCAV55663592
Firmware revision: 80.00A80
Capacity: 1.953.525.168 sectors or 1.000.204.886.016 bytes
512 bytes per sector

Device identification data looks fine.
Max Address according to device ID: 1.953.525.167
Native Max Address Ext: 1.953.525.167
Max Address from DCO: 1.953.525.167
Reported capacity looks logically correct.

ISTM that the drive is correctly reporting its full native capacity via the ATA Identify Device command, and no HPA appears to be in force. This would suggest that the 60MB capacity is a logical problem of some kind.

Where are you getting this capacity figure from? BIOS? OS?

If OS, have you examined the MBR?
