Help with quadra 605 HD
We have 3 quadra 6o5 donated to our non- profit group. They are equiped with only 80MB HD. I have 2 Seagate 2.1 SCSI wide HD I'm trying to substitute without any luck. Does anyone know if it is possible to use these drives with computer and if so what do I have to do to get them to work. TIA?

This should be possible. You need a 68pin to a 50pin ribbon cable adapter.

This is not going to be particularly cheap - about $30 or so. It might be cheaper to buy some scsi hard drives from or some other retailer that sells the older drives still.

A couple of other issues to be aware of:

1) Drive height. The profile of these machines is very thin. You need a small HD to fit in these machines and still get the cover on. Not all HD's will fit in the 605 (same "pizza-box" profile as the LC series and performa 400 series).

2) Current draw. I am not sure of the spec, but the drives can not draw too much current. The power supply in these machines was not designed with power-hungry devices in mind. If you have any PDS cards installed, you will really need to keep an eye on that. I do not know if these drives will cause too much of a problem, but higher capacity drives do draw a little more juice.

3) Heat. Make sure these drives allow for enough clearance for air flow once the cover is installed. These have small fans in them and again, are not designed to deal with a lot of extra heat (a lot of old 2GB HD's ran very hot).

The Quadra 605 case design is slightly different from the LC case designes, although it opens the same way.

If you're planning on putting 7200RPM drives into a 605 you might run into a heat/power problem, but if they're just plain 5400RPM drives they probably use less energy than the 80 meg drives your replaceing. Those drives are old and chowed power.

If all else fails, has a section with >1GB SCSI drives pretty cheap.

I appreciate all the comments. Let me elaborate where things stand. The Quadras I have already have a 50 pin cable, so that's no problem. Also the Seagate drives I have are half height and fit with no problem and power doesn't seem to be a problem. I was told I need a least System 7.6.1 to recognize the larger drive which I have installed but still can't see the drive on the desktop. Also I'm told the drive must be terminated. I don't have a jumper to fit the Terminator enable at the present time. But it's my understanding the drive should still mount even if not terminated. I can see the drive's light flashing as the computer starts up, but still won't mount. Any suggestions would be appreciated.

I assume you have used Drive Setup and SCSIProbe? There is a big difference between a disk being recognized and a volume being mounted... it sounds like the disk has been recognized at least. See if you can get one of the aforementioned utilities to mount the drive (SCSIProbe can be found all over the 'net). If not, you may need a disk driver utility like FWB's HardDisk Toolkit.

We're supposed to sing about piraty things!

One small note about flashing LED's on HD's...does it seem pretty random and then stop once the desktop has loaded or does it seem to have a pattern to it? If it has a pattern, a lot of older drives (and I think a lot of them were Seagate drives) would flash a pattern indicating a controller board problem (kind like the drive is sending out an S-O-S). If this is the case, the hard drive's controller board is bad. The manufacturer may replace it, but you would have to contact them to find out.

You may need to use 3rd party formatting software like Hard Disk Toolkit from FWB.

I want to thank everyone for there help. In my simplemindedness I forgot about formatting the drive, assuming the drives which were used before had been formatted. When I formatted them with Apple's drive setup I was able to get them to work. Thanks again.
