You can only check their condition by using them. What you need to do is
experiment to determine how high a burn speed they can handle.

For example, the CD in the burner at the moment reports:

scsidev: '0,4,0'
scsibus: 0 target: 4 lun: 0
Cdrecord 1.11a05 (i386-pc-os2_emx) Copyright (C) 1995-2001 Jrg

ATIP info from disk:

Disk sub type: High speed Rewritable (CAV) media (1)
ATIP start of lead in: -11625 (97:27/00)
ATIP start of lead out: 333750 (74:12/00)
speed low: 4 speed high: 8
power mult factor: 1 5
recommended erase/write power: 5
A2 values: 26 B2 4A
Disk type: Phase change
Manuf. index: 0
Manufacturer: Illegal Manufacturer code

Note that the above reports that the valid speeds are between 4 and 8.

Since your CDR's are basically of the mystery meat variety, I would start
at a low speed and work my way up until I produced a coaster. Assuming
burning process works, there's not wrong with burning at a lower speed.
It just takes longer and generally produces a more reliable CD.

I would not bother with experimental content or multiple sessions. I
would just burn something useful in a single session.

Keep in mind that you will probably not be able to read the CD until you
fixate it so there's no real benefit to multiple sessions for what you are
trying to accomplish.

HTH,

Steven
