There seems to be something very wrong with my partition table / MBR / whatever. Just recently I have started to get a lot of file system errors although there are definitely not bad sectors as confirmed by Maxtor diagnostics. Partition magic 8 reports that the drive is BAD and gives this error: Error #106: Partition didn't begin on head boundary. ucBeginSector expected to be 1, not 7. When I go to the recovery console in XP and do 'fixmbr' it says there is something wrong with the MBR but doesn't actually fix it. I tried something called Partition Table Doctor which said there was a problem but the 'fix' seemed to involve deleting one the partitions which wasn't a great help, and it was a demo anyway. I have tried to use TestDisk but it doesn't make a lot of sense. Strangely, it says the disc geometry is CHS 24792/255/63 but Maxtor diag says it is 395136/16/63, is this the cause? However I looked at the geometry of another (working) drive and testdisk values also didn't match the maxtor ones. This is what PartitionInfo says: ==================================================================================================== ======= Disk Geometry Information for Disk 1: 24792 Cylinders, 255 Heads, 63 Sectors/Track System PartSect # Boot BCyl Head Sect FS ECyl Head Sect StartSect NumSects ==================================================================================================== ======= 0 0 80 0 1 1 07 1023 254 63 63 48,596,562 Info: End C,H,S values were large drive placeholders.
