I've had a couple of drives go belly up and what you discribe sounds like
the drive is failing. As another poster said try it in another machine. Then
you'll know.

Yesterday I tried the third incremental data backup to a Maxell CD-R disk.
Using the Nero software 5.5.9.13 that came with the drive.
Initial source data of about 200Mg went OK back in May, a 2nd incremental,
about 10mg also ok. 3rd had errors on verify: "Read error on cd file" etc.
Some unchanged sub-directories were unaccessable, even in DOS.

1. Is this disk salvageable? i.e., can I mark the bad tracks and use the
remaining 400Mb for anything?

I grabbed a blank TDK CD-R disk, tried a full backup and the red light
never
came on (Indicating that burning is in progress) errors" "SCSI/ATAPI
command
timeout error" "Invalid write state" "Could not perform end track" "Burn
process failed". (At 32X)

Then a blank K Hypermedia disk, rated 48X, but I ran it at 24X. This time
the
red light came on a while, but then turned orange, and the drive slowed
down.
It did burn something on the disk, but it gave the same errors as the TDK
plus
"session fixation error".

Finally, I used an expensive (Compared to CD-R) Verbatim 24X R/W disk, and
it
did the backup with no errors.

Why would the drive work OK with R/W but not CD-R? Do they use different
heads
or something?

Should I try even slower burn rates for the CD-R disks? Blow it out with
canned air? Any suggestions would be appreciated.
