My son in Kent (long way from me) has 2 HDDs in his PC. It seems that the second one (not the one containing the C: drive) has suffered a problem. It's partitioned into 2 drives and one of them has 'disappeared'. The other is apparently OK.
Could it be a partition table problem?
Is there any software or similar, preferably free, that could help him to view the partition table and repair it?
