Well besides the fact that your program is nonportable and relies on a
Linux proprietary interface introduced recently:
Several years ago, I did some tests with drives and tried to make the IMMED
bit the default for blanking and other things that take a long time.
>From the tests, I can tell that not all drives work as expected if the IMMED
bit is used. Some drives don't acept it at all, other drives behave unfriendly
and it is impossible to find the real end of the operation.
Note that while most ATAPI drives allow to use the IMMED bit, I am not able
to reliably distinguish SCSI drives from ATAPI drives.
