Hi all, >> dd if=/dev/acd0c of=cd.img and >> It gives the error: 'dd: /dev/acd0c: Bad Address' >Try a different block size (and better to use the raw device), like: > dd if=/dev/racd0c of=cd.img bs=8k >...my CD-ROM seems to need a block size of at least 2k. This solved my problem right away.. My CD-ROM also needs a blocksize of at least 2k.. Thanks! >> 'wormcontrol prepdisk double' or 'wormcontrol prepdisk single' >> having done 'ln -s /dev/acd0c /dev/rworm0', error: >> 'wormcontrol: ioctl(WORMIOCPREPDISK): Inappropriate ioctl for device' >The only advide I would suggest here (if it helps at all) is: > ln -sf /dev/racd0c /dev/rworm0 > ln -sf /dev/acd0c /dev/worm0 I did this, but it doesn't make a difference.. Does anybody maybe know of any required options that should be compiled into the kernel? The drive is correctly probed at boot-time.. 'acd0: CD-RW <HP CD-Writer+ 7200> at ata1-master using PIO3' Any help to this last problem would be greatly appreciated.. And Paul, thanks very much for your help!
