Optiarc DVD RW AD-7260S not usable in Ubuntu 11.04

Asked by Tim Cuthbertson

I have a new PC with a fresh install of Ubuntu 11.04. The CD/DVD drive cannot be used - there is no device for it in /dev. When Windows 7 was installed on the PC when it came to me five days ago, the drive worked just fine. When I tried to install Ubuntu from a CD or DVD, the system would boot to it, but when an installation was attempted it would lose the drive and not be able to continue. I ended up having to install Ubuntu from a USB stick loaded with the ISO image.

My system is a CyberPower PC with Gigabyte Z68A-D3-B3 motherboard. The DVD drive is on IDE Channel 1 Master. Nothing else is on that channel.

Today, I found the following messages in dmesg:

[ 1.983919] ata2.00: ATAPI: Optiarc DVD RW AD-7260S, 1.03, max UDMA/100
[ 1.984246] ata1.00: ATA-8: ST31000524AS, JC45, max UDMA/133
[ 1.984250] ata1.00: 1953525168 sectors, multi 16: LBA48 NCQ (depth 0/32)
[ 2.023905] ata2.00: configured for UDMA/100
[ 2.124189] ata2.00: TEST_UNIT_READY failed (err_mask=0x2)

Please help me to correct this problem. I have found many bugs on Launchpad describing similar problems. Some of them have an importance of "High" but a status of "Unassigned". I would be happy to provide any info needed to help fix this problem.

Thank you very much,
Tim

What make and model is the optical drive? Is it an LG?

It is a Sony Optiarc AD-7260S, which as nearly as I can tell is a "rebadged" NEC manufactured drive.

Thank you, I will try that (moving the connector to a SATA II port).

I am still somewhat puzzled. Yes, the proposed answer fixed my problem. But I wonder why the DVD drive worked in the SATA III port in Windows 7, but not in Ubuntu.

Thank you very much.

Maybe sata 3 has issues in Ubuntu. CD drives are dog slow anyway so will not even remotely get to the data speeds of SATA, let alone SATA 3. I wouldn't waste the port on such a slow drive

Your drive is 16x read speed, this gives around 21Mb / second. This will not be ANY faster using SATA 3. Optical drives suck ass. Suprised you even still use them
