I’ve just bought a 4550a burner and I have an odd problem. If I run the drive in UDMA33 mode, reading data DVDs or CDs is very very very slow and exe files aren’t read properly. Movie DVDs work flawlessly.
If I put the drive into UDMA Mode 1, which is 25MB/sec BTW, the drive works perfectly.
I’ve tried a different burner on the machine and that has no troubles at UDMA33.
My drive has firmware 1.06.
Would this be more a firmware problem or a harware one?
I havn’t tried burning yet on either UDMA mode.
