ada1 keeps having timeout and "disappearing" on my zfs.

Hi,

I'm having problems with one of my hard drive disk which is a Seagate 1TB disk on my raidz (all 3 are exactly the same kind).

My disk keeps timing up or "disappearing" so every now and then, I keep having my raidz being in degraded mode, if I just unplug the disk and plug it back and I do
# zpool online tank1 ada1
It resilver and then it goes back to normal until the drive goes "disappear" again

Is it a normal behavior and/or is there a way to fix this?

Oh by the way I'm on: FreeBSD 9.0-RC1 AMD64

and here is the log of all the timeout I see until at the end of the log my disk just goes offline

Code: 
ahcich3: Timeout on slot 26 port 0

And when I unplug/replug the disk

Code: 
ada1 at ahcich3 bus 0 scbus5 target 0 lun 0
ada1: <ST31000524AS JC45> ATA-8 SATA 3.x device

Well if I do
# smartctl -a /dev/ada1

I'm not sure it tells me that my drive is broken considering that I had this problem on my older computer too which had only one disk and that the problem kept happening even after I changed the disks many times, but I get that:

FAILING_NOW is not a good sign. Have you replaced the cables? Is it using the same power supply that was in the earlier computer?
 
I didn't only change the power supply the disks and the cables I changed everything in it it's a totally brand new one I bought in August
 
Check the other disks you have, if they show less lower values of Raw_Read_Error_Rate Seek_error_rate and Command_Timeout then you know this drive is bad.

FAILING NOW is not good.
If you just bought it, you can return it within the warranty.

this is from one of my disks, wich is running for a long time now.

as you can see there are much lower values for almost everything than the values of your new disk.
