Abstraction leakage burning test DVD+R
Hello, After my dump/restore test failed back in May of 2010[1], I finally got around to burning a test DVD after installing about 2.5 inches of semi-rigid foam under the machine to dampen any local vibration. In designing the test, I was under the mistaken impression that buffer under-runs would reduce the amount of space for writing. Apparently, DVD+R media supports loss-less linking[2]. Test Procedure (using ATAPI interface, rather than the newer ATAPI/CAM interface). The man pages do not imply any major differences for this test. The drive in question is a LG drive with the SuperMulti logo. Test procedure: 1.# mkfifo auxout aux45G 2. In other terminals: # cat auxout | md5 # dd if=aux45G count=2197266 bs=2048 | md5 3. Write test disk: # dd if=/dev/urandom bs=2048 count=2295104 | \ tee auxout aux45G | dd of=/dev/acd0 bs=2048 Error: dd:/dev/acd0: Input/output error 679+0 records in 678+0 records out 1388544 bytes transferred in 80.97 seconds (step 4 not completed due to premature burn failure after 684 blocks, 80 seconds (from 'dd if=aux45G'...) (15743 bytes/sec)) Drive spun up at least twice during this time. 4. Read test (in another term 'cat aux45G | md5') # dd if=/dev/acd0 bs=2048 count=2295104 | tee aux45G | md5 Questions: Currently, the drive is locked. Before forcefully ejecting it and risking an new disk, I want to know what may have gone wrong. Was I expecting too much of FreeBSD on old hardware? The hardware is a Pentium-II desktop machine with 256MB of RAM, with a Promise ATA100 controller card. An extra-long 80-wire cable is in use (to ad4). acd0: DVDR HL-DT-STDVD-RAM GSA-H55N/1.03 at ata-1-master UDMA33 ad4: 78167MB Maxtor 6Y080L0 YAR41WB0 at ata-2-master UDMA100 dd if=/dev/urandom of=/home/test Wrote at 4485315 bytes/second: faster than I was expecting (based on linux's slow urandom function), but still slow enough to cause buffer under-runs. So the second question is: do I have to do anything special to enable buffer underrun protection? (with DVD+R's lossless linking feature, no data should be lost.) How important is running ATAPI/CAM? Obviously DVD burning was happening before the release of version 8, as far as I know. If running out of data is supposed to be abstracted away, did I find a bug that only shows up on old hardware or heavy load? (Or possibly drive firmware bug?)

I was mainly concerned that I made a mess of my /boot/loader.conf I am also a little concerned that the DVD only reads a ~1.5MB/s (a little faster than 1x), but it appears to work.

So, I was able to verify the md5 sum by reading only the number of sectors present in the iso file. $ dd if=/dev/dvd bs=2048 count=996586 | md5 I noticed the size discrepancy while doing a binary search using the iseek (dd)(and count) argument(s) to narrow down the location of the corruption.
