RAID 1 degrading


My RAID 1 array keeps degrading after a several weeks pass since the
previous rebuild.

IMSC says both drives are normal.

I’m using WD2002FAEX on an ASUS P6T Deluxe V2 Mobo (Intel ICH10R)

Firmware version on both drives is 05.01D05

Any suggestions what I can do to fix it?

Thanks for your time.


Check if you have the latest BIOS for the motherboard.
