Anyone have a Yamaha CRW-8424S driver?

Like the title says, I'm looking for the Mac OS installer for this SCSI external CD drive. I found one good copy on archive.org in the wayback machine but it's stripped of its resource fork to begin with, so it's functionally useless. I've tried downloading within OS9 and transferring via AppleTalk to no avail. I don't think it's an issue with my transfer setup, the file truly appears to be damaged to begin with.

FWB CD-ROM toolkit doesn't support this drive, nor do the patched Apple CD-ROM drivers from newer Mac OS releases. (I've also tried the requisite SCSI voodoo, with and without terminators, setting the ID to 3)

I would be immensely grateful to anyone who can provide this installer in an internet-safe format.

I'd try installing Toast 4. It comes with a driver that works with many drives. Plus its handy for mounting disk images.


Good luck.
 
Wait, you mentioned setting the drive to id 3, that isn't a magic number for CDs, thats just the default apple used for internal drives. Does the computer have an internal drive too? Is it already using id 3?

Use SCSIProbe to check what ids are available.


What model computer is it?

Thanks for the fast response everyone! This is great advice.
For the sake of reference, I'm using a IICI, so no stock internal drive. Running System 7.5.3

Toast 4 worked flawlessly on the first try! Very pleased to have this very tastefully striped drive going.

Plus you might be able to write CDs... very slowly (x2 perhaps?).

Worth giving it a try for amusement sake, although it will take more than 37 minutes to do a full disk.

The 8424 is capable of 8x write, 4x rewrite, and 24x read.

However, 8x 150KB/sec for write would be 1.2MB/sec sustained. I'm not sure if the IIci is capable of this with anything besides the fastest source disk, and lots of RAM.

I used a Quadra 605 to write CDs with back in the day, and I had to use a really fast hard disk for writing even at 2x, along with lots of RAM cache, or else buffer underruns would occur.
