I've been having a variety of problems burning CDs with atang:
- burncd consistently failing in exactly the same spot in the ISO, and reporting "only wrote 0 of 32768 bytes: Unknown error: 0"
- burncd failing right at the start with "only wrote -1 of 32768 bytes: Input/output error" (this generally happens after a couple of the previous, and once it starts happening I have to reboot)
Whew, glad that I am not only one.. I *just* have wasted two of my blank CD in like fifteen minutes ago, I keep wondering if I created the ISO files in the wrong way or was it burncd's fault.. Until now here..
I get like this: ===================================== # burncd -f /dev/acd0 -e -s 6 data NT2004.iso fixate next writeable LBA 0 writing from file NT2004.iso size 662576 KB written this track 410656 KB (61%) total 410656 KB only wrote 4096 of 32768 bytes: Unknown error: 0
fixating CD, please wait.. =====================================
I tried the another ISO and I get the same thing by stopped at 32768 bytes.
I am going to use cdrecord for now, hope it will work ok.
Cheers, Mezz
- burncd getting stuck in acdcld for a long time while fixating
- a *lot* of "sensekey=ILLEGAL REQUEST error=4<ABORTED>"; fixating a CD causes about half a dozen TEST_UNIT_READY failures, and I occasionally get READ_BIG, START_STOP, PREVENT_ALLOW and SET_SPEED failures as well, all of them with "status=51<READY,DSC,ERROR> sensekey=ILLEGAL REQUEST error=4<ABORTED>"
I've discovered that reducing the buffer size in burncd fixes at least the first problem, and possibly the second, but not the third. I've attached a patch that adds a command-line option for that (the default will still be 16 blocks at a time, but you can specify anything from 1 to 64 on the command line)
The drive is an LG 8400B with which I've previously had little or no trouble; prior to atang, it burned CDs just fine at 40x with a failure rate of precisely 0.
