[lug] growisofs w/Plextor 740A

[Gary Hodges]

I posted this to linux.debian.user and haven't received any responses. 
I've since installed the same model drive on a very similar machine I 
have local access to (the one in question is in Nevada) and the drive 
worked as one would expect. I have a few extra drives so I think I'll 
just send out another, but maybe someone here will have a suggestion 
that will get things going.

Some additional info and my original post to l.d.u below.

Cheers,
Gary

Sarge install, all updates.

I had a DVD drive fail recently and replaced it with a Plextor 740A. I'm 
now having problems writing disks. With a very small file as a test 
things work out fine (i.e. I can mount and view the file contents after 
writing) using the command I have used for a couple years:

growisofs -M /dev/scd0 -l -r -J /data/tmpdir

If I write something larger, e.g., 30MB and run the same command as 
above it apparently writes OK but when I try to mount the disk I get the 
following:

mount: block device /dev/scd0 is write-protected, mounting read-only
mount: Not a directory

I'm using all the same commands I have used successfully for almost two 
years. An older copy of growisofs also produces the same behavior. Is 
this an issue with the drive?
