Syquest Drives - 200 vs 88

I was handed a pile of 88mb Syquest disks - ostenisibly Mac formatted - a while back and I decided to have a go at them tonight. The only Syquest drives I found in my pile were the original 44mb and the later 200mb (model 5200C.) Everything I can find on this drive (which isn't much) declares that is is backward *read* compatible with 44mb and 88mb cartridges. That's fine, reading is all I want to do. My test platform is Win7 x64 (boo hoo I know...but it's convenient and there is a working 'dd' I've used many times for hard disk imaging.) I first tested the drive with a 200mb pack I already had. It mounted the cart, presented it to the OS and allowed me to dd the cart to an image file which mounted in a Mac emulator. I declared the drive good. Trying 88mb carts results in consistent errors. The drive sounds like it's mounting it, clicks a bit, spins up and down and finally settled on a 5-green, 5-amber blink code. According to this chart: http://www.kassj.com/articles/sqtable.html that means "incompatible cartridge." My carts are all Syquest-branded. Beyond that (and the possible Mac formatting,) I know nothing else about them. The real rub is this - once it displays that error code, the drive _disappears_ from the SCSI chain. Neither the OS tools nor a SCSI explorer utility find it. Insert the 200mb cart and it's back again; not even a power-cycle needed. The drive does appear with a SCSI ID before inserting a cart; a mounted cart is not necessary for it to present itself. So, theories: - This drive isn't 88mb compatible after all - *All* my carts are bad - The carts were degaussed and thereby lost some sort of low-level formatting or other ID method that the drive uses to recognize them - There's some sort of mode jumper or switch (hardware/software) to kick it into 88mb compatibility mode, if such a thing exists. I have no manual for these drives - I need some sort of driver to enable reading 88mb carts; I don't think this is the case - most OSes should simply see them as removable media; it's the drive's job to sort out cart compatibility Any experience/insight/advice is appreciated here. Also offers of a 88mb Syquest drive :) -- jht
