Hello!
I'm having this weid problem. Building a 386 with MSDOS 6.22 and everything works perfect except the floppy drive.
Some times, not allways when i change disks and type DIR it shows the same contents ad the previous disk. The only thing i do to fix this is a reboot but its pretty annoying.
Anyone experiences this or any clue where to look? Thanks in advance.
add the following line to your config.sys (assuming the drive is a 1.44MB set as A:)
DRIVPARM=/D:0 /F:7
this should (through omission of the /C switch) inform DOS that your drive does not support the Disk Changed line, so it will no longer assume the disk is the same every time
Thanks! It works. You think it can be the controller who not support disk change?
Yes, it could be the controller or drive. Or a jumper setting on either
Does DOS actually cache the root directory or last-read FAT blocks, or something like that? I always thought it was too simple and miserly with RAM to bother, unless you ran smartdrv.
Could it be that there is a micro-switch in the drive that is sticking in the on position sometimes?
That is the only thing I can think of that would cause an intermittent issue like that.

Definitely. I have this every time on my IBM LPX 486 motherboard (not sure what it's from, a late PS/1 or early Aptiva?). Drives (including my Gotek) are known-good and do the disk change thing on any other controller I have.
