I have a mac LCIII. I want to upgrade the HD from the old 250meg SCSI to... well.. somthing bigger that is newer and less likely to fail.

What I did so far: I took a 4gig Seagate 10k cheetah and put it into an external scsi enclosure (set it to ID 0 and enabled termination on the drive). I hooked it into my powerbook 5300 and created eight 500meg partitions formatted in HFS. This went great and they mount fine on my Powerbook. I then booted the powerbook into OS 7.6 off the install floppies. The drive showed up fine with all 8 partitions and OS 7.6 would have happily installed.

The problem: Satisfied, I hooked the drive into my LCIII via the scsi port in back. Turned it on, booted into OS 7.6... nothing... no drive. So I took it out of the enclosure and put it on the internal ribbon cable. Nothing. Took it out... put it back on the Powerbook 5300, booted into OS 7.6... bam.. there it is??

So I guess this HD is too good for the LCIII?? Anyone out there successfully add a multi-gig HD to their LCIII? Any ideas on a good alternative?'

Thanks!!

Try setting the ID to 3 or 4. I think the Mac will assume ID O.

i know that the HDD in my Performa 475 is 1.2gb and is formatted in one partition the whole size of the drive and works flawlessly. it runs system 7.6.1, the HDD is a quantum fireball. and have a external scsi LaCie CD RW burner. all work great

Quantum Fireball = Awesome

Well, I already tried Id 4 and Id 1. Forgot to mention that. It is ID 0 now. At any rate it works flawlessly on any ID (including 0) on my powerbook.

The drive is a 4gig 10,000RPM Seagate Cheatah. But SCSI is SCSI and Ive never had this issue before? Ive tagged new drives on old SCSI-1 buses before. I just assumed this should work. Its too bad because all I have are Seagate Cheatah drives (3 of them) all the same. Maybe I should look for a 1gig drive on ebay.

Well.. Any other suggestions? Thanks for your time!

What are you using to format it? I guess it's possible that the LC doesn't like drivers that the 5300 has put on the drive. I'd get a copy of the hacked HD Setup (the one that supports third party drives) and see if you can reformat it with the LC...

I had a slight suspicion that maybe that had somthing to do with it. Ill look in my 9gig archive of Classic mac software and see if I have that. If I dont any idea where to find it?

Thanks!

There's a tutorial on how to create your own version here:

Wow thanks although this version is 7.3.5. Apple says 7.3.5 requires OS 8, and a power PC or 68040?? Is this true? Ive heard around that version 1.6 is the last one that should be used for OS 7.6 and also the last one that will run on a 68030. I could be wrong and please correct me if I am. Would this patch work on V1.6? Also... the site says HD SC Setup... is this different from plain ol HD setup for OS7...err sorry for all the questions.

Ok yeah they are different... Ok I downloaded it and will patch it... then see what happens!!

I thought that the LCIII was one of the models that required an enabler of some sort?

Virtually any 50-pin SCSI drive ought to work. I wouldn't bother with so many small partitions. Make 'em about 1.75 GB. (IIRC old Mac OS had a 2 GB limit or something so you want to avoid that.) When a Mac boots and searches for a drive is starts with ID 0, then works backwards from 6 (7 is the ID of the computer itself). The internal CD-ROM is typically found at ID 3 on Macs.

The LCIII needs System Enabler 003 placed in the System Folder when it is booting System 7.1. But it has absolutely nothing to do with using huge HDs or anything of that sort.
