| U320 2.5" SCSI HDDs in vintage Macs? |
Posted by: olePigeon on 2011-12-13 14:19:48
Has anyone tried this yet? You can get 36GB 2.5" Ultra320 drives for $25. Pretty cheap. I was wondering if an Ultra320 drive would even work on an old PowerBook SCSI BUS (or any older Mac's SCSI BUS.)

Well, electrically, it will work fine, with an SCA -> 40pin SCSI adapter. I've never seen such a beast, but you could make it work with an SCA -> 50pin adapter, and a 50 -> 40pin adapter. However, that's not going to fit inside of a PowerBook.
I suggest a 2.5" SCSI -> IDE bridge (HARD to find, these days), or a 2.5" SCSI -> CF adapter, like http://www.artmix.com/pdffiles/CF_PM_Manual2_203_Eng.pdf.

Ah. Well, perhaps not a PowerBoo, but could be a cheap source of large HDDs for other vintage Macs.

Some of the newer U320 drives will not however even allow you to fall back on older and slower rates by jumper. I have a small stack of 36gb drives that are useable in nothing but my SGI gear because they are not compatible with the older SCSI standards, even with an adapter.

Interesting... I have purchased a HP branded, Seagate made 72.8 GB Ultra-320 SCSI disk which (thru an inexpensive SCA-to-50pin adapter) works perfectly with my old Macs. That includes the SE/30, at least for those partitions below 2 GB 😉
Now you have mentioned SGI... I'd like to reserve a partition on it for backup of my SGI Indy's 18 GB HD, but that's another story... Will the SGI understand the Apple Partition Map?

I believe that Irix supports HFS.
I'm not sure though if FX will be okay with it though. You might have to at the least manually partition the drive.

Stumbled upon this thread again through a different thread. It's cool that someone tried it. I'm thinking about getting a 15k RPM drive for my QuickSilver since I now know it works. 🙂

i think it depends on the brand and wether they decided to have backwards compatibility.
i have a 36gb 10k Fujitsu, and with my sca to 50 adaptor it did not work with the older scsi bus,
however i did have a Ultra 160 PCI Card from a powermac G3 server, and that runs the drive good,
i have the card and drive sitting in my powermac 7500, i had to use xpost to boot OSX panther DVD in order to format it.

Would be neat if we could get people to try out different brands so we know which work or not. Then we'd have a source for cheap SCSI drives (for now, anyway.)

It may depend on the particular adapter... I have a SCA 36GB Fujitsu which doesn't work at all with my "regular" 50-pin adapter, but it's fine with a "better", terminated adapter.
Maybe we could start a page on our Wiki, in order to collect all experiences and tested models, including jumper settings etc. :b&w:
