Severity: normal
Hi,
i experience with eSATA and USB failures to read
DVD+RW if the drive tray gets loaded automatically
or if it is still blinking from ongoing loading.
E.g. with dd:
$ dd if=/dev/sr0 of=/dev/null bs=2048 count=1
dd: opening `/dev/sr0': No medium found
$
dmesg shows no related entries.
It does not help to load the tray explicitely
$ eject -t /dev/sr0 && \
dd if=/dev/sr0 of=/dev/null bs=2048 count=1
dd: opening `/dev/sr0': No medium found
$
But short time later it is well possible to read
$ dd if=/dev/sr0 of=/dev/null bs=2048 count=1
1+0 records in
1+0 records out
2048 bytes (2.0 kB) copied, 0.0684895 s, 29.9 kB/s
$
The system was installed via
debian-504-amd64-netinst.iso.
$ uname -a
Linux debian 2.6.26-2-amd64 #1 SMP
Tue Jan 12 22:12:20 UTC 2010 x86_64 GNU/Linux
Reading with autoloading still works with an IDE
drive at /dev/hda.
Burn programs have no problem with autoloading
on the affected USB/eSATA drive.
Have a nice day :)
Thomas
