I have a problem which I address to 'Asus P6T WS Pro' motherboard,
but it may be also a matter of the disk; I would like to hear some
suggestions on how to proceed with the issue.
My PC has two 1.5TB Samsung Sata disks, and some time ago I have
noticed that some files that I copy to one of the disks (photos)
are getting corrupted, while I know they are just fine on the source.
With SMART data for the 1st disk (taken with 'HD Tune') I see:
- Raw Read Error Rate: Current 99, Worst 34, Thres. 51, Data 4375 (status: Failed)
- Current Pending Sector: Current 91, Worst 91, Thres. 0, Data 359 (status: warning)
- Ultra DMA CRC Error Count: Current 100, Worst 100, Thres. 0, Data 1 (status: warning)
Initially I did not notice the 'Raw Read Errors' (was using diff. software).
Seeing 'Ultra DMA CRC Error' I started to suspect that it may have something
in common with onboard Sata controller - I have read about similar problems
for Intel H67/P67 chipsets.
Maybe that was too quick decision, but I decided to start with external
Sata controller first - before deciding to do something with the disk
(as I have quite a lot of software there etc.).
I have selected 'Asus U3S6' controller.
Card was put into PCI-e x16 port (card itelf is x4).
After installing U3S6 card and attaching both disks to it I have
noticed that it requires 'AHCI' controller/storage mode (and I
had 'IDE' mode selected so far). In general - I see that U3S6 card
is properly recogized by the motherboard - I get additional options
in Bios for teh U3S6 card, allowing to select external controller
mode (Disabled, Raid, Legacy - if I remember well; also allowing
to select whether U3S6 Boot Bios should be enabled or not).
Now with disks attached to U3S6, Bios settings like 'Storage mode: AHCI',
'U3S6/Marvel: enabled/Legacy or enabled/Raid', and 'U3S6/Marvel: onboard
Boot Bios enabled' I see:
- PC is going through own Bios initial steps, then goes to U3S6 Bios,
which seems to properly see 2 Sata disks attached (reporting 1.5TB size,
3 GB/s speed).
- U3S6/Marvel Bios then tells it cannot boot out of the devices attached
(I don't remember exact communicate, but it is something like 'No
bootable device found.' or similar). btw. PC is on Windows XP Pro.
- Then PC goes to other devices (CD or pen); as there no other possible
boot devices in the system - it just stops.
- I have noticed that even without the U3S6 card PC won't just Boot
if I select 'AHCI' storage mode instead of 'IDE'.
So now come the questions:
- how wrong/right was I with addressing the issues to the Sata controller?
Should I rather address them to the disk? (the other disk I have does
not note any problems).
- Do I suspect right that Windows XP needs to be installed with some
additional drivers to be able to boot in AHCI storage mode?
Can that be overcome at this point, where it was already installed
with 'IDE' storage mode?
- am I doing any mistake with mentioned Bios options selection?
I have noticed that U3S6 board itself also has some Bios, which
I can enter - but there is actually nothing to select there..
