first to summarize:
1) ubuntu 10.10, ASUS M2N32
2) 5 internal 2Tb seagate LP drives working great on motherboard
3) 2 new 2Tb drives on ASUS PCIE expander card are NOT WORKING
4) PCIe expander uses Marvell 9123 controller, is this my problem? [card is SATA 6Gbps capable but the drives are just SATA 3Gbps]
5) what would be a better expansion card, i don't need RAID
now more detail:
===============
i have a ubuntu 10.10 box up and running. the motherboard is an ASUS M2N32 and the sata host adapter is listed as an MCP55 controller. it also has a SIL3132 RAID controller, and i am not using hardware (nor software) RAID so this controller doesn't show any associated hardware with it (in disk utility program).
the 6 drives plugged into this motherboard work great. OS drive is 160GB, the other 5 are 2TB seagate LP (ST32000542AS). i recently expanded this system by purchasing an ASUS SATA expansion card with 2 ports. i plugged in two more of the seagate drives.
everything worked fine, briefly. after copying ~30Gb of data, the system will lock up the drive, it goes completely dead. i put both of the new drives into a windows 7 box and they are performing fine. then when put back into ubuntu (NTFS partitioning), they will lock up and "die". one of them won't even re-format inside ubuntu now.
the ASUS expansion card has a Marvell 88SE9123 PCIe SATA controller chip. i have not found any special drivers (or i don't know how to find them, more precisely). i have read some anectdotal evidence that the 91xx controllers are not Linux friendly.
does anyone have this issue, or some advice how to fix it?

but it doesn't seem the author or responders came to any solution other than disabling NCQ and i'm not sure i want to do that necessarily, any comments?
thanks in advance
