You would need to unmount the filesystem and mount the new one when replacing
the floppy.
Comment 2 Chuck Ebbert 2007-11-27 17:54:33 EST
Does unmounting the filesystem and remounting it work?
Comment 3 Brent R Brian 2007-11-27 21:30:24 EST
Filesystem was NOT MOUNTED ... I was doing a

dd if=floppy.img of=/dev/fd0

got an i/o error (bad sector??), it stopped, every time after that accessing
with dd would claim READ ONLY FILESYSTEM ?  Like it was not clearing the error
from the  floppy controller ????

I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the Fedora kernel.


I'm closing this bug as its difficult to see how we can troubleshoot this issue.
The reporter is starting with what they accept is bad media for reasons unknown.
Please re-open if you feel this is incorrect however we will need to debug the
issue using known good media only. Thank you for taking the time to file the
original bug anyway...
