View Full Version : Third Hard drive for 7600

03-21-2001, 09:49 AM
I have two hard drives in my 7600. One is the original 1.1G and the other is a Seagate 9G. Can I install another one internally or do I have to get rid of one of my older ones?

Probably not recommended -

But - that being said, I have a colleague, who shall remain nameless, who was able to stuff a third hard drive vertically behind the CD-ROM bay in his 7300... (i.e on its side).

- this is the same individual who using cardboard as internal shelves in his machines...

OK. I keep seeing this "YMMV" and I'm can't figure it out. I know the following.
IMHO = in my humble opinion
IMO = in my opinion
FWIW = for what it's worth
FYI = for your information
BTW = by the way
And a couple more that escape me. PLEASE, YMMV = ??????????? http://www.macgurus.com/ubb/confused.gif

Rog. Since I see there's no OEM "blessed" way of putting a third drive in I'll have to ditch the 1.1G one. Thanks.

There is always the option of removing the floppy. Seems kinda funny, and definitely not "blessed", but I have done it. In fact, I have a machine running like that right now. Needed a little....umm....massaging to get it to fit in and be firmly mounted, but it is there. No bubble wrap or cardboard . http://macgurus.com/infopop/emoticons/icon_wink.gif

I also ran a 7500 with 4 hard drives. Yep. 2 in the "normal" places, one in the floppy bay, and one mounted to custom-drilled holes in the side sheetmetal. Sure, the drive was mounted sideways, and I needed a "Y" adapter to power it. But at the time, I needed some semi-permanent larger storage and file-transfer space. Thank goodness I had no long PCI cards or I woulda been screwed. This was a few years ago, before I got a little more sensible and had a couple "spare" enclosures lying around. I am all better now, though.....yeah...sure.

That's The Kinkiest Friggin' Power Mac , Poppy?


Well, nevermind. What did YOU intend that to mean?

the approved method is to use just two drives in the two drive bays.

we routinely pull the plastic trays and floppies out of our 7300/7500/7600 machines and run them without their covers on so we can easily swap drives around and PCI cards.

no problem, in my experience (uh, ok, IME), running without a floppy.

strangely....in the past, long away in the dim years of the Mac, I recall being taught that floppy drives were required, else the Mac wouldn't boot, or wouldn't run correctly, or something. I was taught by a master, so I have no doubt that it was true, at one point.

I run bench machines without floppies all the time.

IIRC (if i recall correctly) my SE/30 would not boot without the floppy drive connected; however, I may be confusing this with the Plus or Mac II.

On the original topic, back in 1994-5 I hacked two SCSI HDs internally on my SE/30. I spliced a second connector to the original power supply since this was before I learned of y-adapters. Also handmade my SCSI cable by crimping a 3rd SCSI connector into the center of a 2-connection ribbon. For vanity I mounted two LED holders in the top right above the screen for activity indicators. I thought I was so cool my shit didn't stink any more.

This is NOT recommended, I was very ignorant about heat and power consumption issues. A more knowledgable friend sobered me by expressing amazement that I had not blown the power supply when I told him the SE/30 had two HDs, a Rasterops PDS video card, a Daystar CPU accelerator, and eight SIMMs installed.

I then acquired a second SE/30 shell and started planning where to cut the opening for an internal CDROM, but the metal support skeleton was awefully inconvenient. I sold the whole shebang before I figured anywhere aside from a rear-panel vertical opening for a spindle-mount CD drive.


my free 7500 is nickel and diming me to death.
