These were common way back when but did happen.
Also, some IDE drives have you put jumpers to indicate Master, Slave or CS. Did you try all 3 settings/jumpers?
I have an old Toshiba Satellite A60. The old 30gb Toshiba HDD (MK3025GAS) has died. I have bought a 60gb Toshiba HDD (MK602GAX) as a replacement.
My problem is that I can't get the bios to see the new drive and boot off it. The bios for the old dead disc says under 'Built in HDD = Primary IDE (1F0H/IRQ14)'. With the new HDD it says 'Built in HDD = No Drive'.
Is there something I need to configure or have a bought a non compatible HDD ?
