Hi All, Just trying to set up a PVR type device and would like to throw in a feature to detect what media (if any) is inserted into the DVD burner. Currently I'm running FreeBSD 5.2.1-RELEASE-p1 with atapicam and the burner device is a CDRW <LITE-ON DVDRW LDW-451S> as reported by the kernel boot messages. The dmesg gives me this info cd0 at ata1 bus 0 target 0 lun 0 cd0: <LITE-ON DVDRW LDW-451S GSB6> Removable CD-ROM SCSI-0 device cd0: 16.000MB/s transfers cd0: Attempt to query device size failed: NOT READY, Medium not present How would I go about checking the media if it's a blank, non-blank or RW disk? C or C++ code would be great. Cheers Tim -- Tim Aslat <tim@spyderweb.com.au> Spyderweb Consulting http://www.spyderweb.com.au P: +61 8 82243020 M: +61 0401088479
