Hello,

got an hp pavilion dv 6560ec that came with a aforementioned optical drive. The drive occassionally lost and appeard among my drives and finally is completely undetectable.

The label on the drive says:
S/N:626727402546
Model: DS-8A1H 03c
HP part number: 445954-HC0
HP Spare part number: 449935-001
Firmware : WH66
CT: 7591801WBUT1YQ
Manufacturer: Phillips and Benq Digital Storage Corporation
H/W:01

Symptoms:
- its drive letter does not appear among drives in my computer
- no DVD/CDRom drives icon in my Device Manager, hence no yellow excl. mark either
- when I insert the drive in my laptop it spins for a bit and that is it
- does not do anything else (if I had not fysically seen it, I would have thought there is none inside:rolleyes:
- when I try to remove it, reboot, insert the thing, look up and "add new hardware", it is not listed there, neither I can see any DVD rom icon when trying to select it manually

I have been continually toiling to get it work again with no success over couple of months now.

Steps tried so far (in vain):
- total virus check of the laptop (Norton Symantec)
- upper/lower filters deleted in Registers
- got another compatible optical drive (although used but the seller claimed it was tested and functional - my laptop did not detect it either)

- when checked if I had cd/dvd driver at all with DriverAgent application, 2 were listed among "Disconnected Devices" : CZWDWXE W9QJC1UBSX SCSI CdRom Device and "Z0262L EJE040U SCSI CdRom Device" (needless to say the drive was sitting in the slot)

Any ideas?

Thank you in advance!!!

Boot into the BIOS and see if it is detected in the BIOS. Sounds like a faulty drive. Laptop drives have a shorter life span than desktop drives. You can try removing reseating the drive, to verify a proper connection. You can also boot into the BIOS and see if it's detected there...if not, it is most likely faulty.

Hello and thanks for replying.
Unfortunately, I did buy another optical drive. It was used and I did not have the possibility to check whether it really is functional as the seller claimed. But none of them are recognised by my laptop. I always just slide them in without crewing in the little bolt, but I guess it can't be the case... can it?

As far as Bios settings concerns, the only thing regarding CD-rom that there is in my Bios is boot sequence. CD-rom is set on first place. Could updating BIOS help?

Most BIOS will display the hardware that is detected (HDD's and CD/DVD drives). In any case, if it's not there already, updating won't help.

And if it's not working with two different drives, very likely there is a hardware issue. Either the motherboard controller, the drive connectors, or possibly just faulty drives (less likely now that you have tried two).
