My Config in Sig below;
Have put a RAID 5 on new Seagate 418AS 500Gigs (Primeabgb)
Issue is :
Every few days (5-6 days) one of the RAID members comes up as degraded and the system goes for a rebuild of that drive.
Now this happens on one of two drives only, and the rest have no problem.
I suspect PSU is unable to take the system load, but I am looking for advice on other potential points.
My BIOS is the latest possible from ASUS.
Also, I suspected SATA Cables to be the issue so I got new ones from Bikey with Latches on both ends (& UV!!!) to be sure.
Any ideas anyone?
Feel free to comment as I have tried loads of things and may have missed out on something.
 
not sure if this can be done in a RAID 5 setup.....swap the power cable and the data cable (not sure if u can change the no. of the drive in RAID, since u would be changing the data cable) with another drive or to make it simpler just put another data cable, observe as the days progress....
 
Already done that, bought 6 new cables from Bikey with latches n rt angle.

Also changed the power connectors, split the drives among lines.

No help so far, still see occasional degrades.
 
Are you seeing the same disk going bad again & again or any disk goes bad ocassionally. When u see the degraded state during the bios could u try rebooting the machine or plugging the power off totally and plugging back after a minute or so... and then check if it shows degraded. Let me know the output.
 
also remove those two HDD's & check them in different machines.

i also had the same problem which was caused by drive failure but in my case it was RAID 0.

Already Tried.

Shows up as degraded.

By mistake, I 1nce switched on while drive was disconnected, and it came as failed, ofc.

also remove those two HDD's & check them in different machines.

Tried, also ran seatools bootable cd on them, no errors reported, and SMART check was within parameters.
