i have a genuine problem here. i noticed my backup cdrw's had stopped working at some point. upon furthur investigation i find i cannot mount cd's full stop. titan# mount -t cd9660 /dev/acd0c /mount cd9660: /dev/acd0c: Invalid argument the above command makes the drive light flicker for 3 seconds then the error. this is NOT a hardware problem. i get the exact same issue with my brand new dvd drive. here is what dmesg gas to say: acd0: DVD-R <HL-DT-ST DVDRAM GSA-4160B> at ata1-slave WDMA2 da0 at hpt3740 bus 0 target 0 lun 0 da0: <HPT3xx RAID 1 Array 3.00> Fixed Direct Access SCSI-0 device da0: 190782MB (390721957 512 byte sectors: 255H 63S/T 24321C) Mounting root from ufs:/dev/da0s1a cd0 at ata1 bus 0 target 1 lun 0 cd0: <HL-DT-ST DVDRAM GSA-4160B A301> Removable CD-ROM SCSI-0 device cd0: 16.000MB/s transfers cd0: cd present [1 x 2048 byte records] note this was working perfectly. i suspect that some how my ata device has gone "bad" some how. let me get the obvious replys out of the way: yes i have googled nothing i can find has even touched on a fix. yes there is a disc in the drive no it is not an audio disk. there is nothing else connected to the ide ports.
