I can make an iso image from a CD with a small amount of data (about 68M) no problem. However, when I try to make an iso image of a cd with a large amount of data (around 600M) it dies after writing about 500M. I'm using a command line of 'dd if=/dev/acd0c of=test.iso bs=2k'. On the console I get error messages like this: acd0: READ_BIG command timeout - resetting ata0: resetting devices .. done acd0: READ_BIG command timeout - resetting ata0: resetting devices .. done acd0: READ_BIG command timeout - resetting ata0: resetting devices .. done The dd processes get stuck in physst state according to top, and can't be kill'ed, even with -9. According to ps their state is DWL or DWL+. The CD is a generic OEM 24x EIDE drive, and I have hw.ata.atapi_dma="1" in /boot/loader.conf. The CD is identified as: acd0: CDROM at ata0-master UDMA33 at boot time. I'm using 5-current built on 3 June. I'm happy to do what I can to test patches, upgrade, etc. I haven't had a lot of time for FreeBSD lately, so I haven't been tracking -current closely. This build has been very stable for me other than this problem. I generally don't have problems with this CD drive (that I've ever noticed anyway) but this is the first time I've tried making iso images. It's entirely possible that this CD reader is just a POS, which is fine, but I thought I'd ask just in case. Doug -- If you're never wrong, you're not trying hard enough. Do YOU Yahoo!?
