Some mistake appeared while I try to copy iso image to HDD.

`burncd` utility write CD data correct (without any error)
but, after that i write it back by `dd` and at the end of writing got error
message in the log.
# ls -la
# burncd -e -s 4 -v -f /dev/acd1c data Source.iso fixate
adding type 0x08 file Source.iso size 96 KB 48 blocks
next writeable LBA 0
addr = 0 size = 98304 blocks = 48
writing from file Source.iso size 96 KB
written this track 96 KB (100%) total 96 KB
fixating CD, please wait..
# dd if=/dev/acd1c of=Test1.iso bs=2048
kernel: acd1: READ_BIG - MEDIUM ERROR asc=0x11 ascq=0x00 error=0x00
# ls -la
Dest file is bigger on one block (2048bytes). It block filled by
zeroes (0x00) in Test1.iso
Trying to do the same at <CD-540E/1.0A>, and so on:
# dd if=/dev/acd0c of=Test0.iso
kernel: acd0: READ_BIG - ILLEGAL REQUEST asc=0x64 ascq=0x00 error=0x04
But now dest file has correct size:
It's looks for me, like `dd` want to take exess block from device.
But, when i mount any of the `acd`, `df` shows correct size of mounted
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/acd1 96 96 0 100% /cdrom1
96/2= 48 blocks
Only one ISO is dump with `dd` normally (with out any error messages).
FREEBSD-5.1 RELEASE. But it burning not on my TEAC (on LG CD-RW by
Neuro BurningRom, which are now inaccesible for me).
If i rewrite this "correct" compact disk on another CD, new copy readed
with the same error messages.
Other CD-ROM burned by me and not, reading with such error (when trying to
get exess block).
I probe reading from acdXc with various ISO image (burn and then read).
AFAIR, my ATA controller and CD-R/CD-RW (both) is supported by 5.x FreeBSD.
But, maby i mistaken. :(
The same things happens on Linux at the same machine, but at that time
i not concern on this trouble.
Greeting any suggestions
Thank you very much, and sorry for bad english
