3rd hard drive on the ZIP bay

[psax]

Hi Gang

Any tip on instaling a 3rd Hard Drive on the zip bay on a G4 533 SP?

Thanks!

Should be no problem at all did it the other night. Couldn't get the screws matched up but it seems pretty snug in there and I aint takin it on the road anytime soon . Good Luck

How did you configure the drive, for slave 2? I'm about to do the same in my dual 800...

I made the Hard Drive the Master and the DVD drive the slave. No problems and it's been in my G4 for over a year!

Hi anly beware of the bus speed, becuase that bus its slower than the other bus, because of the CD drive or DVD drive, I think. I had trouble allocating to disk to record 10 tracks at once, while playing 10, for example. the thing is that if you put the system disk in the Zip bay you can have the other bus at full speed. It works perfect in a G3 350 !!! with 2 7200rpm drives, i have an 733Mhz L3 cache machine and my Hard disks are slower than the ones in the G3 amazing!!!

It's because the 2nd Bus is a ATAPI (basicly removable media) bus. Bandwidth isn't exactly that of the ATA bus.

On a side note,

Just want to tell you guys/gals doing this to make sure you don't cover up the access hole in the bevel.

Running 3 7200RPM drives is gonna cause a lot of heat.

Just a FYI so you guys don't start melting things.

Enjoy!!!

It's now been 1 year since I've been running 3 7200 rpm drives in my G4/350 Yikes (HD #3 is in the Zip location...no problems as of yet! Go for it...good luck! "Ol 88

Why did you do it this way? My dual 800 G-4 has the Superdrive as the master(ID=0), so I made the thrid drive the slave (ID=1). Works fine so far, but I am curious if there is some advantage to doing it the other way around.

In the old SCSI-based PPC's, at startup the CPU would check (in this order), SCSI Bus 0 (the internal SCSI Bus), ID-0 - ID3 (which is where Apple would place the CD-ROM ID# at) then through ID6, switch to SCSI Bus 1, ID's 0-6 (as the Mac is always ID 7) and finaly the floppy drive searching for a valid system folder (with which to boot).

In your case where, the one thing that you have going for you is in the case of a terrible crash, then, when you insert your MacOS installer CD, it will immediately boot the CD instead of checking the rest of your ATA devices.

I'm assuming this is why gaffer set it up this way.

The main "gains" for that particular setup, is we all know that a hard drive is faster than a CD/DVD/ or Superdrive.

Thanks Billbo, I was curious if there was something I was missing by not making the Superdrive the slave. It is working fine in the above config, and appears to run just as fast as the ATAbus drives. Perhaps the Superdrive is on a faster ATAPI bus for DVD writing purposes. Anyway, it's working fine, and no heat problems either.

Thanks to all!!!!!!
