|

* lets us know quickly whether the device name actually points
|
|
* to a floppy disk drive.
|

* Then, obtain any drive options. We're mainly interested to

* see whether we're currently working on a device with media
|
|
* density autoselection (FDOPT_AUTOSEL). Then, we add the
|
|
* device option to tell the kernel not to log media errors,

|
* since we can handle them ourselves. If the device does
|
|
* media density autoselection, we then need to set the device
|
|
* type appropriately, since by opening with O_NONBLOCK we
|
|
* told the driver to bypass media autoselection (otherwise we
|
|
* wouldn't stand a chance to format an unformatted or damaged
|
|
* medium). We do not attempt to set the media type on any
|
|
* other devices since this is a privileged operation. For the
|
|
* same reason, specifying -f and -s options is only possible
|
|
* for autoselecting devices.
|
|
*
|
|
* Finally, we are ready to turn off O_NONBLOCK, and start to
|
|
* actually format something.
