Has anyone here successfully installed a second internal IDE HD on a Rev. 1 Yosemite G3 (HD brackets side by side, not stacking). The Apple TIL says its not possible, but xlr8yourmac.com says that you can do it in some cases. They seem to indicate the only stumbling block is finding an IDE ribbon cable (for 2 drives) that is long enough to plug in to both drives in that configuration. Has anyone here actually done it successfully? Any tips? Where can I get ahold of a cable that is long enough?

Any help is much appreciated. This forum is long overdue. Thanks MacNN!

I've got a 27 gig IDE HD slaved in the zip bay (slave to the DVD rom drive) and a 6gig (salvaged from my old G3 Beige) slaved to the main 6gig IDE in my BW, which is also Rev 1. I've also got a 9gig scsi drive attatched internally to an Adaptec 2930 card.
So far they seem to work (for the last 8 months or so anyway), although the System profiler says some pretty wierd things about the 2nd 6 gig drive.
The easiest one to fit in terms of cabling is the slave to the DVD, just put it in the Zip bay, and use the zip cable (although the actual metal case of the zip bay makes it mildly fiddly). I got a standard PC 2 way IDE cable from a local computer fair for the 2nd 6 gig one.
If you can borrow a spare hd for a while, it's worth testing your machine to see if it can handle the drive. As the admins here usually say... "your milage may vary"

You can also buy a cheap PCI ATA card and run both drives off of that, or leave the stock drive there and buy *two* new ones to run off the ATA card.

Don't put the hard drive in the zip bay...I've heard it's not designed to take that heat and can screw things up pretty bad.

On the Rev 1 B&W the computer will recognise both Master and Slave IDE hard drives, but support for both devices on the same bus wasn't all the way there. You can use each channel on it's own, but if you try to transfer data from one device on a channel to another device on the same IDE channel then you get data corruption. The finder copy may not find problems, but if you use a tool such as retrospect which verifys the data, then you notice the problems. I wanted to install a larger drive in my B&W. How I was able top get around this problem was by cisconnecting my DVD drive and placing my Primary hard drive there as master. When the data transfer was complete I removed my old hard drive and have been using only the internal 22 gig 7200 RPM IBM drive.

Can you recommend any specific ones which have little or no known conflicts and a good reputation? What exactly is "cheap?" I've already got an Adaptec 2930U SCSI card in there, so the cost of the ATA card would have to be less than the difference between an IDE drive and a SCSI drive.

what happens cuz that's where I put a slave 26 gig ide..... the mounting bays at the bottom really suck....

I've been told that your hard drive can overheat if it's put there.

Machine: rev1 B&W G3
I've also got a 27BG IDE drive in the zip compartment and it's been fine for 5 months now, with the machine sometimes running for 48hrs at a time, never had a problem. Also, I have a slave attached to the main hard drive and do not have any dat corruption issues, even when copying betweeen the 2 drives. I have only maxtor drives as they do not seem to suffer from the data corruption that drives like seagate or IBM have in the rev1s.
