I hooked up a NEC ND-3550A on IDE using the 80 conductor/40 pin IDE cable at the middle connector on the primary IDE. My only hard drive is on SATA. The DVD/CD drive is the master, no slave present. Read operations "freeze", like nero reads and windows media player. CD burning has a very low success rate. I didn't try DVD. I then bought a BENQ DW1655. Same problem. I then connected the drive to to the end connector on the IDE - no improvement. I have bios 201. Any tips? ( I am able to read data CD's and data DVD's).
