Is this problem always occuring from a cold boot, or also
from a warm (re)boot? If only from a cold boot I would
suspect your power supply is a bit too small and isn't
spinning the drive up fast enough. If that is the case then
see if the bios has a "quickboot" or similar setting that
you could disable to give the drive more time to spin up and
be ready.

Measure the power supply voltages and check the drive with
the HDD manufacturer's diagnostics. You might see if there
is a motherboard bios update that addresses any same/similar
issues.

A 3GB drive cannot do any faster than ATA33 and you should
not need an ATA66/100/133, 80 conductor cable. However,
with an old cable there is a potential that it isn't making
good contact, as IDE cables with their insulation
displacement connectors are not meant to survive alot of
plug/unplug cycles and may not age as gracefully as other
connector types. I would try another (known good) cable
just to rule that out, but again for a 3GB HDD, it need not
be an 80 conductor cable instead of 40.. |
