Not sure what to do about this.  It looks like a failure in the IDE driver.
Perhaps you could start by telling us about the IDE hardware, which driver
is in use, etc.

Is the floppy-disk bug still there?

Hi Andrew and all others,
1. The floppy bug does not exist anymore. Congretulations!
My IDE hardware is Intel north and south bridge, the standard idecd driver is in use.
As I was all the time suspecting a timing error I'm looking forward to testing Mike´s patch and I guess the bug will be absent then.
Lots of thanks for Mikes work!
Big regards and thanks for the late reply

Uwe
