[ILUG] cdrecord making coasters

[Gavin McCullagh]

Hi,

if anyone has any idea what might be causing this I'd appreciate any
information.

I'm using the Debian cdrecord clone (as root) to burn new 700MB verbatim
CDRs.  The disks are 52x compatible, the drive claims 24x but cdrecord
drops back to 16x so that's what I let it use and dropping to 8x doesn't
seem to help.  It's making coasters faster than I can make coffee to put on
them (about 1 in every 2 fails so far).

I see the messages about unresolved issues with Linux-2.5 and newer.  It's
a little depressing to think that this is still the case.  I'm using the
ATA:1,0,0 syntax to use the 2.6 atapi interface instead of scsi.  Is this a
bad idea?  I'm willing to use the ide-scsi if that's the issue but I don't
want to use 2.4.  I certainly never used to have this problem but I haven't
regaularly burnt cds in a while.

The output contains "Medium Error" which might perhaps indicate a bad disk
but I'm very unsure.  The full output is below.

Does anyone know what might be going wrong?
