112340 2003-01-11 01:44:00 There is one byte in the MBR which, if it is wrongly set, makes the disk unusable by MS. I'm surprised that the IBM programme coughed: I got the impression that the IBM engineers wrote that because they occasionally ran into problems. :D

Have you got Nortons Disk Doctor, or the old Nortons NU? Those could fix it, but I'm not sure whether they fix it "automagically". It's a rare condition, but the old books about DOS disks mentioned it as a real annoyance.

Can the linux fdisk not create a DOS partition on it?

112341 2003-01-11 07:58:00 Yes Linux fdisk can create a dos partition but dos fdisk will still not see it.
I have since put this hdd in a p120 machine I have and guess what??
Dos fdisk then works. Putting the freshly fdisk'd and formatted hdd back into the 486 still gives me a "error reading fixed disk" message. Putting the hdd out of the p120 into the 486 gives me the same fdisk error. It appears that the problem is with the 486 and not the hdd although once up and running the 486 goes fine with dos, linux or win95. It is a Digital Venturis 466 with a Digital bios in case this makes a difference.
Strange huh??

112342 2003-01-11 08:35:00 Error reading fixed disk is usually caused by a hardware problem, such as an incorrect jumper, misconnected cable, etc. Merlin (503)
112343 2003-01-11 10:04:00 well I just reinstalled windows because I'd killed my MBR and couldn't seem to get it back :_| -=JM=- (16)
