I think you hit the nail on the head with DMA. I did some internet searching in general on the 3512. Apparently it has problems with Seagate drives whilst using DMA. Guess what drive manufacturer made my HD? Guess why it works fine in PIO and freezes under OS 4.1 FE?

OK. Time to try a different HD.

Edit: Tried some new things tonight.

The company that sold me the 3512 said that they had tested it and found it to be in working order.

I did some more research on the web. After reading that the 3512 had problems with Seagate drives, I decided to try the 3512 without my Amiga HD (a Western Digital HD mind you) attached. I put the HD SATA lead to the motherboard, and the DVD lead to the 3512. It booted fine. I could access the DVD drive fine. I put the OS 4.1 FE CDROM in and rebooted. It hanged at the splash picture. I waited. I waited some more. It never got to the Workbench. I rebooted without anything in the DVDRW, and it booted. I turned off the SAM and attached the NTFS drive (a Seagate HD) to the 3512 alongside the DVDRW. I tried to boot. Even though it was booting from the motherboard SATA2 port, it hanged during the splash screen. I think my particular 3512 doesn't like either AmigaOS, or DMA... or Western Digitals and Seagates... whatever the case...

I'm sending the 3512 back.
