DaynaFILE SCSI Floppy Disk Drive (5.25″: 360k, 1.2M, 3.5″: 720k, 1.44M)

In the late 90s I picked up a DaynaFile, a SCSI attached floppy drive, with a 360k floppy that someone had thrown out at my work. It sat neglected in a drawer for years until I finally got a power supply to get it working again. Looking around the internet I was able to find a copy of the 2.2 enabler, the 4.1 enabler, a copy of the 5th edition (1989) of the manual, and a brochure (1987), but limited technical information. As usual, I’m using my blog to document what I’ve found and pieced it together so I don’t forget, and to hopefully help others.


SCSI on Windows 10 64-bit and Windows 11: Adaptec AHA-2940 (29xx) Ultra, AIC-7870 (78xx), or 29320LPE Ultra 320 and LSI Logic

When I first started playing with 68k macintosh systems around 1999/2000 (a Macintosh Plus) I connected an external SCSI drive to my Windows 98 system and was able to use an early version of Basilisk II with SCSI pass-through to format the hard drive.  Now 18 years later, SCSI is an obsolete technology, and in general is not supported under the latest versions of Windows and the the Macintosh OS, although I believe Linux still has support.

Luckily a skilled person on the internet has made 64-bit compatible drivers to support some of Adaptec’s cards under Windows 10 (sorry I’ve found nothing for the latest version of the Macintosh OS).   I’ve personally tested the Windows 10 driver for Adaptec AHA-29xx cards with an AHA 2940U PCI card. Others have tested additional cards on Windows 10 and Windows 11.
