I recently upgraded my computer (an old P3) with a larger HDD (Western Digital 800BB) 80gig - a big improvement from the 6 gig disk I had. Took 10 minuted to swap over, a couple of hours loading software then all well.
A neighbour asked me to do the same for her. Then my troubles began.
Installed disk as a master in place of her old disk. No disk detected. Spent a week trying every combination I could, eg setting up as a slave to her old drive etc. No luck at all. Installed her disk in my computer - worked OK, so I loaded software (XP + office etc). Got it working fine then reinstalled to her computer. No joy.
Finally in desperation I installed the drive in an external housing I had, connected to her computer vis USB port. Worked fine. So now we have her old (4gig) HDD for boot up then the new unit connected externally for storage.
I don't like the solution so any suggestions re what could be stopping her computer from recognising the 80 gig disk? NB her computer similar vintage to mine - forget the actual spec but can look it up if necessary.

Could be a bad motherboard or a bad cable. Did you have the jumpers set correctly on her system?

Could be that her BIOS won't recognize such a large drive. Try partitioning it into sections smaller than 37 gB and see if it's recognized.

If set as Master, it should have gone on the far end of the cable - if as Slave then it should be connected to the middle connector on the cable (this is old stuff and may not apply to newer systems - but it can't hurt them, so it's worth a go).

Also, if it still doesn't work - try the Cable Select jumper setting on each of the connectors to see if that fixes it.

Then, if that doesn't work, try it on the other IDE channel to see if it works there. Also try switching the cables to see if there's a difference there.

Carefully inspect the pins on the drives and motherboard to ensure that none are bent.
