Do I have a dodgy cable? I will have to change that tomorrow. But more info. The old drive played DVD movies etc. OK, but slowly it became worse until I couldn't read any one of them 9 times out of 10. CD play back/burning was OK 100% all the time though - so I guessed the dvd laser (whatever it does) was dead - hence why I bought a new one. The new drive works perfectly, but for the udma33 issue. If it was the cable, why would it read/burn CD OK, but not DVD sometimes on the old drive? hdparm -I /dev/hdd: ATAPI CD-ROM, with removable media Model Number: TSSTcorp CDDVDW SH-S202J Serial Number: Firmware Revision: SB00 Standards: Supported: CD-ROM ATAPI-3 -4 -5 -6 -7 Configuration: DRQ response: 50us.
