I replaced the disk drive on my Hummy about 9 months ago using a Seagate ST 3320311 CS and a StarTech IDE2SAT convertor and it has worked well. Recently the Hummy reported a hard disk error. I checked the disk using Sea Tools and the short tests were OK so I replaced the convertor and the ribbon cable but no change. Although the Sea Tools tests were OK the disk does not appear when I check the computer on Windows Explorer. Anyone got any ideas?
