I've got 4.4-RC #0 with a Yamaha CRW2100S SCSI CD-RW When I issue the following command: # dd if=/dev/cd0c of=cd.img bs=2352 I get: dscheck(#cd/2): b_bcount 2352 is not on a sector boundary (ssize 2048) dd: /dev/cd0c: Invalid argument 0+0 records in 0+0 records out 0 bytes transferred in 0.004639 secs (0 bytes/sec) I've tried it on two audio CD's but to no avail. I have been able to dd a data CD with bs=2048. Any suggestions? -- Regards, Doug To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
