: I need help in installing the new IBM Deskstar 22GXP Hard Drive in my new G3 350.
I have installed it on the internal ATA 1 bus using it as a slave drive to the internal 12 Gig Quantum Fireball. It is crashing my system erratically when transferring or capturing large clips. Disk First Aid reports different errors each time I test the disk and now my old hard disk is reported as corrupt in the HFS wrapper partition.
Is it something to do with the new ATA66 interface on the new drive being incompatible with the old ATA 33 standard? I have confusing reports about 40 or 80 pin cables?
Has anybody installed one of these drives successfully?
: thanks

Timo,
I've got a new G3 (and a 22GB IBM) sat along side me, so I'll see if the drive works okay with the G3 - which was the reason the two are in such close proximity!!
I'll report back tomorrow. If you don't hear from me - email me a reminder.
One possibility occurs to me, which is that the IBM may come set as an ATA66 drive by default (I think both the 22GB and 25GB models we had in did), and that this might be confusing the Mac.
If this turns out to be problem, you'll need to find a friend with a modern Windows PC who is prepared to run a little program I can send you which changes the drive so that it identifies itself as an ATA33 drive, not ATA66.
I'll try to check this aspect, too.

I seem to have a solution to the problem. I have found that taking the original Quantum Fireball 12gb drive off and mounting it in position 2 in the middle of the G3 and mounting the 22gb IBM at the back so that the IDE cable passes through the IBM first works. The Quantum is still the master drive and the IBM the slave. Both drives are now working reliably but I am still not convinced that everything is fine and dandy - might the 66 and 33 still be conflicting in some way?
Anyway let me know how you get on.
Timo
Timo,
I think that the position on the cable can be critical - the master goes on one end and the slave sits in the middle. Hopefully, your problem is now solved!
If there is any problem related to ATA66, I would expect it to be one of slow data transfer.
On a Windows PC, if the drive identifies itself as ATA66, most motherboards - which are looking for a response saying, "I'm ATA33" - will be confused and assume the drive is NOT ATA33, and since all they know about is ATA33 and pre-ATA33 drives, they treat is as though it were an old, slow drive and don't enable DMA.
I was wrong in my previous response - I don't have the 22GB drive here, I'll try to remember to bring it over tomorrow and run it up - set as ATA33 and ATA66 - and see if the G3 notices the difference ie runs the drive at different speeds.
