Sometimes, it may be when I have a disk in that has the tab set to read-only access, when I try to format, I will get the error "ioctl(FDFMTTRK): Input/output error" when trying to format a floppy disk, subsequent attempts give a device is read-only error, with no way to restore write access. By the way, it even does this after I realized the tab was set to read-only and changed it to read-write!
Tried different kernel/fdd yet ?
Ignore this bug, I suspect it is just my crappy hardware. :(
Closing old bugs.
