An interesting thing about the Vulcan hard drive controller + PSU replacement combo for the IIGS is that it actually makes more sense to separate the PSU from the controller! With some creative rewiring, it's possible to put a SCSI drive inside the PSU replacement and run it off a SCSI controller (which will give you access to bigger drives and better performance), and the Vulcan controller itself can then be used in another machine using CompactFlash cards instead of the gigantic first-gen IDE drive it shipped with. Unfortunately, the Vulcan is infamously picky about what drives it accepts, and it takes quite a lot of trial and error to find a CF card that will work. So far I've only gotten two to work - a 32MB and a 64MB, both Viking branded.
On the Drew ][ blog, there's a post about a utility for Linux called part_vulcan that can create a partition map for a Vulcan hard drive controller. I've tried to mirror what was done to run the utility in the blog post as closely as possible. I used what I'm reasonably sure is the the same Linux Live CD, compiled the program and ran it on several CF cards. The partitions created on the cards will show up in the boot menu of the Vulcan, but when I try to run the Partition Manager program on the install disk in order to format them I get the usual "COULD NOT READ VALID PARTITION BLOCK. PRESS 'Y' TO CREATE NEW ONE." error with it failing when I press 'Y'. The ROM on my Vulcan card is the Vulcan Gold ROM (2.0) and the Partition Manager version is 2.04, both of which are the last versions known.
Has anyone sucessfully managed to get this program to work? I've only gotten certain 32MB and 64MB cards to work on the Vulcan, but I've noticed that it's possible to dump a .DD (in my case using WinHex) image of a card that has been formatted successfully and restore it onto a card that does not format successfully using the Vulcan utilities and it will work. Ideally, it should be possible to generate images of successfully formatted cards of any size.
