Cool. My father still has a 5.25" drive in production use - he has large numbers of 5.25 disks containing old work, and maybe once a year needs something off one of them. Works fine on his W2k box. > The operating system reports the drive > is available and definitely makes contact with the drive (visual > confirmation: LED).

Drive might be broken, disk might be broken, disk might not be formated, and finally make sure you know what kind of 5.25 both the drive and the disk are. 8088/86 machines stated off with single sided 8 sector one @160k, then double sided 8 sector (320k), then single sided 9 sector (180k), then double sided 9 sector (360k). That was the standard. AT machines (i.e. 286s and later 386s & 486s) used 1.2Mb 5.25" disks. These AT drives could read 360k PC disks (PC = 8086/88, BTW) but if you wrote to one there was a very good chance it would never be readable by a PC again, because the 1.2Mb AT drive had a read/write head 1/3 of the size of the 360Kb PC drive, and often the mark it left was too small to be read by larger PC heads. For that reason I always treated 360k disks as read-only media on 1.2Mb drives. As other people have said, /dev/fd0.1200 and /dev/fd0.360 look like you friends here. Personally I don't bother compiling fd stuff into the kernel any more. - -- W.
