    Default Source for replacement HD's for SE/30

    Hi All,

    I've a Mac SE/30 - in my mind, the best ever compact Mac (no discussion to be entered into) - that powers up perfectly and can boot from floppy with no problem, but it can't see the internal Quantum 40 MB drive.

    i suspect that it has seized up due to the stiction problem that plagued these drives in the late 80's/early 90's.

    Does anyone have any suggestions as to which drives I can replace the Quantum 40 MB drive with?

    How much do you want to spend?

    An Australian based enthusiast has developed what is called SCSI2SD which emulates a SCSI HD using an SD card. They're about $100 and I've been very happy with mine!

    Another vote for the SCSI2SD - any 50 pin SCSI HDD you buy these days will be almost as old as the SE/30, and past its use-by date, and while it may still work perfectly for now, who knows how long it will continue working. With a SCSI2SD you can use microSD cards that are dirt cheap in capacities much bigger than most 50 pin SCSI drives.

    Yes I also miss the sound of a SCSI HD booting.... Maybe some company will make mechanical SCSI HDs again some day for the nostalgia...

    Sounds like you just need to hack the SE's ROM so it plays a recording of the sound while it boots...

    I presume there's some kind of limitation as to how big a card you can use for this? I mean, how much can System 6 / 7 address??

    Both of my SE/30s have dead HDs. I might have to get one of those SD SCSI things...

    I've got two 4 gb as cards that work fine on system 7.5 on 68040 macs.

    The SCSI2SD itself I believe is compatible with any SD/SDHC card.

    As for the Mac OS - the maximum volume size in System 6 and System 7 is 2GB, however in 7.5 it was increased to 4GB, and in 7.5.3 I believe it was increased to 2TB. However be aware that on older Macs, block sizes on large volumes will be huge, as such files will appear to consume more space than they should (this was one of the reasons why Apple switched from HFS to HFS+). For example, a file that consumes 1K on a 40MB volume will actually consume 32K on a 2GB HFS formatted volume. As such, even back in the day it was generally considered best practice to partition any drive bigger than say, 1GB into smaller partitions.
