Those are 3 good suggestions. I will take them in order and tell what I
discovered.
1. I don't seem to have an 'eject' command on my system. Do you know if
there is a package that I could install that would give me that capability?
2. I ran lsof at various times and there was nothing accessing the drive
after it was umounted.
3. What I didn't say when stating the problem (because I didn't think
there was any connection at the time) was that there was already an ide
cdrom drive in my computer. I got the external usb CD/DVD drive to get
DVD capability. When I was looking around in the /proc/sys/dev/cdrom
subdirectory per your suggestion I noticed that the 'info' file had 2
columns, one for the ide drive and one for the usb/scsi drive. All the
other files ('lock', 'autoeject', etc) only had one value (0 or 1). So I
wondered to myself :
a) Which drive does the single value apply to? and
b) Could having 2 cdrom drives be causing a conflict somewhere?
So I went back to my kernel configuration and disabled support for the
ide drive. When I rebooted , the first thing I noticed was that the
entire /proc/sys/dev/cdrom directory no longer exists. Also the usb
drive now ejects properly!
So unless anyone can think of anything better, I guess i will have 2
different kernels, one for using the ide drive and one for using the usb
drive.
Thanks very much for the help..
p.s. Changing the /proc/sys/dev/cdrom/lock setting didn't have any effect.
