Further info: a complete surface scan of the disk with SmartControl ran fine with no errors reported. The disk is physically fine, but there is a problem with the partition table which either testdisk is not resolving properly, or keeps getting corrupted at the boot stage, perhaps by a virus...
A bit more info: testdisk also reports that there are hidden sectors on the disk:
Disk /dev/sda - 750 GB / 698 GB - ATA WDC WD7500AACS - 0
Hidden sectors are present.
size 1465147055 sectors
user_max 1465147055 sectors
dco 1465149168 sectors
Not sure...
