Last christmas, I bought a LG dvd burner for my computer because it had lightscribe.
I bought it used with no warranty.
I have it in a dell that has only one IDE channel, the hard drives are sata, and it has no floppy.
On the other channel I have a sony dvd rom drive that I was using just for ripping and playing dvds.
I configured both drives as cable select, and the LG drive never worked right.
It would burn fine, but it absolutely would not read discs properly at all. It would generate all kinds of errors, you wouldn’t even be able to install software on a cd with the drive it was this bad.
I thought a firmware update would solve it.
Then I was messing around inside the computer, and decided to set the LG drive as slave instead of cable select, and the sony as master.
The lg drive works fine now, reads all discs perfectly.
What an odd thing, i’ve configured optical drives as cable select with no ill effecting results until now.
