CRX160E-A1 as in: http://www.storagebysony.com/products/crx160e-a1.html Box says its a Spressa. Don't know what significance that has. > Could you comment on the quality of it? It doesn't shake the way the 32X Hitachi CDROM did when spinning at top speed. It fit in my case. Connectors and screw holes lined up. It reads everything I've asked it to. It has written everything I've asked it to (about (8) 12x Memorex 650MB/74min CD-R's). Guess it plays music too because NT tried to play a music CD I wanted to make a "working copy" of for possible destruction in my car's glove box. > > Took far less time to figure out "burncd -f /dev/acd0c -e -s 12 data > > 4.2-RELEASE.iso fixate" than it took to install the $%^&@ Windows > > software (which I waited until the next day to attempt).

I also have a Panasonic SCSI 7502 CD-R 8x read 4x write. The Sony "CD Express" software says something about SCSI and might work with this drive too (haven't tried). I need to find some nice short 12" or 18" SCSI cables so I can connect my external DDS drive and my external Panasonic CD-R at the same time. But have been thinking about hooking both CD-R's up at the same time and try to make coasters by burning two at once. The CD Express package bundled with the Sony drive wants to use C:\TEMP\ for scratch but I have only 150 MB free on C:, 1,800 on F: so in Options I set F:\TEMP\ and it still won't because "not enough space on the temporary drive". Took about 30 minutes of trying every fool pretty icon command before most the way across the command strip I got into the "Disc Explorer" where I could view the current CD's tracks. And noticed a button in the bottom right corner saying, "Global Image" or such, something GI, which I noted earlier is the extension they use for their disc images. Finally I could manually copy an image to HD. Then elsewhere write that back out to CD. See how easy this GUI makes burncd look? :-) I need to figure out the right way to read raw CD images with dd in FreeBSD as after making a 4.2-RELEASE I thought to use dd to read it piped into md5 to make sure it was the same as the image burncd used. Believe it was shorter coming off the CD-R. Used to do this using cdrecord to read the size of the image off CDROM, then subtracting two 2048 byte blocks from that, dd was happy and accurate. Think in writing this I found my problem as "systat -v" showed 32k blocks being written, I used 32k to read with dd, and fell short because an exact multiple of 32k wasn't written in the first place. At least that's my guess. > Wow, I don't even know how to interpret the output of systat -v! > Thanks for any detail you could give. Much of systat is nonsense to me too, but bottom left corner of "systat-v" is something I understand: Disks da0 da1 acd0 sa0 sa1 fd0 pass0 KB/t 0.00 0.00 0.00 0.00 0.00 0.00 0.00 tps 0 0 0 0 0 0 0 MB/s 0.00 0.00 0.00 0.00 0.00 0.00 0.00 % busy 0 0 0 0 0 0 0 Where "acd0" and "MB/s" (megabytes/sec) intersect was 1.76 most of the time during the burn. The "KB/t" (kilobytes per transaction) line said 32. "tps" is Transactions Per Second. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
