You have a lot of options for replacement hard drives.  I've never 
heard of any Mac model needing specific Apple sanctioned drives, and 
I've been managing Macs since before they supported SCSI drives.  The 
only thing that required Apple sanctioned drives was Apple's 
formatting software, and lately they've even dropped that 
restriction.

I'm not sure if you can use a drive with an 80 pin connector and use 
an adaptor.  I think the drives with the 80 pin connectors are wide 
devices, that is they have twice the data lines that allows faster 
data throughput.  If the drive can sense that it is connected to a 
narrow cable, maybe it will work correctly.  I suggest trying to find 
a 50 pin hard drive.

One other consideration is physical size.  It's been a long time 
since I've seen the inside of a Classic II, but I remember that it 
was somewhat cramped.  There may only be room for a third height 
drive in that space.

Having said that, I must caution you that some drives won't work with 
NetBSD even though they work fine under Mac OS.  I've run across a 
few that just refuse to work with NetBSD, such as a Micropolis 4110 
that refuses to work under NetBSD on both the macppc and the mac68k 
ports.  I'd suggest buying a drive that offers a money back return 
policy, just in case.
