I bought a BTC 1004 drive late last year. I have not yet been able to write a good DVD.
I thought the problem was just not good media and didn’t have much time to test it.
Recently I found a friend with the same drive and he has had no problems using datasafe disks (RITEKG04 media). I tried those and still had problems so have bought a new liteon drive to replace the BTC. I have had no problems with the liteon drive.
Attached is a KProbe test of a write to Ridisc (RITEKG05 media). PI spikes over 400 and PO spikes over 200. Why do I get most of the errors in the second half of the disc?
I have tried the drive on two different computers running WinXP, Amd 1800+ and Amd 2400+, 512mb ram, DMA enabled, Drive Firmware from 43, 48, 50, 350, 450. Currently on 450.
I believe the drive may possibly be faulty but can’t return it as I have moved countries.
I would appreciate any suggestions as to why most of the errors are on the second half?
