The wrong drive (DVD) pops out !!! The converse is also true where ejecting hdd pops out the CDR.
I suspect that this is causing some of the problems I am encountering with this machine and would appreciate any help in figuring out what is going wrong or where I should look.
I have tried rolling back to an earlier kernel (2.6.15-1.2054_FC5) but have the same issues.
Physically, the CDR drive has been set to master & the DVD to slave (which should end up as hdc and hdd respectively) but something is amiss and they seem to have been unaccountably swapped.
This also means (?) that I cannot mount or burn on the cdrom drive which is becoming an issue.
