I have a seagate 400Gb hard disk model ST3400832ACE. My problem is, my PC won't see it. It's been in my machine for ages. I was having problems with it loosing the boot sector so I did a backup and used my machine recovery cd to reformat it and re-load XP. All that worked fine, then I took the hard disk out and put it in my other pc as the secondary disk to copy the data files back on, but my other machine sees it as a 136Gb drive. When I put it back in the main machine (remembering to put the jumper back so its the master disk), the machine will no longer see it. When I go into setup it thinks it has no hard disk. I've tried to change it to manual setup but there is no information on the disk label as to cylinders, sectors and heads. I've looked on the Seagate web site and contacted their help desk but they don't have the information. Does anyone know what the settings are or any other way I can get my pc to see the disk.
