I have heard from some that newer Quantum drives will not talk at 10MB/s reliably with the aic7xxx based cards. This has not been my experience with my Empire 2100S. You could try setting the Sync negotiation rate down to 8MB/s to see if this helps you out. Have you ruled out a VL-DMA problem? Are you using active terminators? If you have other things on the bus, can you target one of them as the cause of the timeouts? -- Justin T.
