Hi:

I got one Seagate 750G and 2 WD 750G SATA drives, and I want to create a RAID-5 array.

I got 2 motherboard one is ABIT IP35 and one is INTEL DG33TL, both has INTEL Matrix Storage and 6-port SATA, and both supports RAID 0,1,5,10

One weird thing is INTEL storage manager sees Seagate drive using SATA transfer mode generation 1, and WD using generation 2. Why is that?

-----------

The problem is the original ABIT motherboard IP35 was sent for RMA and don't know when it will be back. So I'm trying to create a RAID-5 on another INTEL motherboard (DG33TL) then move it back to IP35. Will this be a problem? Will data corrupt occurs? This is what I fear.

DG33TL is a weird board, and the SATA plug on the motherboard is laid out like this

4, 5, 2, 3 (where 3 is eSATA)
0, 1

If I created a RAID-5 on this board using 2,4,5 (in that sequence) and then I moved it back to IP35, will I have a problem?

And do I have to create a RAID-5 also using 2,4,5 (in that sequence) on IP35, or I can create a RAID-5 on 0,1,2 on IP35 (in that sequence)?

Or the only way to move from one machine to another machine is to create the RAID on the same channels, like both on 0,1,2?

And if I mixed up the sequence, I'm screwed, right?

First of all, you don't re-create the RAID array on another machine -- you enable RAID, let the system auto-detect it, and maybe adjust your boot priority afterward.

So it comes down to enabling it and then auto-detecting it. Plugging them in the wrong order won't create a brand new array and wipe your data -- it'll either be recognized or not... It should be auto-recognized. You can test this with your existing installation, by switching the connections -- power down, switch, power up. If it auto-detects and passes some basic file system tests, then it should also be fine in the new machine once RAID is enabled.

I seem to recall an article ( gotta find it ) on migrating to Intel Matrix RAID. Some of the info may apply to what you're trying to do. As for the mode1 and mode 2 diff you are seeing, it could be that you forgot to remove the jumper from the Seagate Drive. They ship with the jumper set to SATA 1 mode.

You might hunt around here for info on migrating RAID modes.
Also d'load the manual for your particulat chipset. e.g., " ich9R "
