Tricky one this ..but perhaps someone out there can help ?
I have aquired one of these dual function drives ..standard IDE connection on the rear.
It supports both CD and PD (phase change differential).
I currently have it in an XP build ...and it reads PD discs ..sort of.
I aquired a couple of these cartridge encased discs with the drive ..which appear new and unused ..
The discs are hard formatted when viewed by sliding the cartridge window open manually.
I can read the small text file already on the new disc from manufacture and can copy this to my desktop.
What I cannot do is write to the disc ?
I presume I would need suitable drivers to perform a write ?
I believe this type of drive was an optional extra fitted in the Compaq Deskpro 4000 or 6000
..so unlikely there would be suitable drivers for XP or even Win2000
..but maybe Win95 or 98 ???
I do have old PC buids for these OS ....but again ....no native support for either, I have tried already.
I haven't tried Windows NT.
Does anyone know where I might find suitable drivers for this rather unusual bit of hardware as I'd love to see it work.

Seems to be Compaq drivers for DOS, Win 3.x, Win 95 & (possibly) NT - see the latter mentioned elsewhere but can't track the drivers atm. Have linked the others

DOS / Win 3.x

Win 95

EDIT - there's also this driver package from IBM which might work
(includes NT & OS/2 as well)
