Hi group,
By way of addendum to my earlier post on udev rules
and my CD and DVD drives, /dev/hdc and /dev/hdd.
At first the drives were'nt found then modprobeing
ide-generic.ko fixed that. But the links under /dev to
the drives were being mysteriously incremented. So
ide-generic was compiled with the kernel. Didn't work.

Every time I boot the links are incremented and the
optical drives don't work. Floppy and SATA hdd OK.
Here's /etc/rules.d/*cd*:

I commented out the extra lines but it didn't help.
Isn't the '+=' in SYMLINK+="cdrom" computerese for
'add a one'?
FWIW, from the boot console I see something new:
Running hdparm
HDIO_SET_DMA failed Operation not permitted
for /dev/hdc and /dev/hdd
