Is there reliable way to query drives for media presence? I have tried query_disk_change but it returns 1 if called without media inserted (it correctly works if media is present when it is called). I need it for CD-ROMs (IDE or SCSI) and possibly for other drives with removable media like floppy, Zip, Jaz.
So far I tried with two IDE CD-ROMs and floppy and all show the same - query_disk_change always 1 when no media is present.
The reason is I'd like to avoid media access when it is known no media is present. The kernel is 2.4.17.
TIA
