I tried all commands using fd0 and fd0.1440 this time, but I still get the same error messages (with "fd0c" in them). When using fdformat, i get this: nomad# fdformat /dev/fd0 Format 1440K floppy `/dev/fd0'? (y/n): y Processing fdformat: ioctl(FD_FORM): Input/output error (no extra kernel messages this time) The same happens when using fdformat fd0.1440. After this, the disk becomes unreadable on another PC, so I have to fdformat it again. Note that this was with different disks that are ok on other machines and on the same machine under dos/windows. The drive can even format disks under dos, and running scandisk with surface scan enabled doesn't show any faults. The same problems appear whether or not the disk is formatted on the machine itself, or on another one. > His drive works OK under windows; it is possible but very unlikely there is > a hardware problem. > > His problem will probably disappear if he uses a suitable device fd0 or > fd0.1440 rather than fd0a. > > This also applies in writing an image using dd, but here it might be > advisable to use the sized device fd0.1440 or the traditional raw device > rfd0.1440 > The problems stay the same ... :(
