Think I've discovered another issue with the floppy driver.....
Basically, if won't play ball with a 360K 5.25" Matsushita drive (JA-551).
The mobo's BIOS is configured for one drive (A:) - 360K 5.25"
There's no secondary FDCs, and the JA-551 is the only FDD connected.
If I boot FreeDOS (1.0 and an earlier version), it formats, reads, writes a number of disks perfectly
If I then boot Linux (System Rescue CD 1.1.4), I am unable to mount or format any DSDD disk :-(
With System Rescue CD, I have to modrobe the floppy module; and that then gives me a
....with minor number 4; which is correct, as I understand things.
If I then format with :
....it fails everytime with FDFMTTRK : Input / Output error
It also fails with :
It's the same story with Slackware 12.1 (booted from CD)
Under FreeDOS, I can simply type :
format b: /u
....and it formats perfectly everytime
incidentally, FreeDOS sees the FDD on b: because FreeDOS itself uses A: (bootable floppy image on the FreeDOS CD)
Earlier in the day, I was formatting 1200Kib disks in a HD 5.25" FDD under System Rescue CD, so the problem is confined to 360K DSDD FDDs :-(
If further info is needed; please don't hesitate to ask
Cheers for now
