Makes no difference.

Again, makes no difference, except that the error has
CDB:  53 00 00 00 00 00 23 69 C0 00

Claims that the amount to be written is larger than the available
space on the disk. WTF?

=====
# growisofs -Z /dev/hdc=dvd.iso
Executing 'builtin_dd if=dvd.iso of=/dev/hdc obs=32k seek=0'
:-( /dev/hdc: 2295104 blocks are free, 2320832 to be written!

And of course, my local Debian mirror is down at the moment, so
this'll have to wait until tomorrow.

Again, made no difference, just claimed that the write failed too.

This is most annoying. I have never had a single problem with burning
isos under Linux before. (in fact, it almost burns them too well) I
may have to swap the drive to my Winbox and burn them over there.

I'll try =)
