Repeated storahci and disk errors.

I am seeing repeated storahci and disk warnings (below) for a pair of Western Digital Caviar Black drives I used Windows to created a mirrored RAID for. These drives are used to storage data and do not have the OS installed on them (the Windows 8 Pro is on an SSD).

There warnings (samples below) tend to occur in batches of 25 pairs or so running about 2 hours usually 8 to 20 hours after I stop using the computer.

Occassionally, the drives just disappear from "My Computer", but I can always see them in Disk Manager. When this occurs, I simply reboot the machine to restore access to the drives. The drives automatically start resynching and everything behaves normally.

For many months, turning off "Sleep" eliminated this problem. Recently it started happening with sleep turned off. I have not installed anything other than Windows updates.


Reset to device, \Device\RaidPort1, was issued.
source: storahci

The IO operation at logical block address 12c10d68 for Disk 0 was retried.
source: disk

(The locgical block address changes)


What should I be looking at?

I am guessing that you have Scaned the disks?

Yes - I have scanned the disks. No problems.

I think this problem is getting worse. Today, I have a new experience - I am getting Reset to device, \Device\RaidPort1, was issued (Storahci) errors while using the computer. They are occurring every few seconds to minutes. I am not seeing the corresponding disk errors. It does not look like I can access those drives at the moment (clicking to open one and it just hangs).

Can you plug the drives into different headers?

Try running smartmontools (smartctl) against your drives. Smartctl reports a log of the last 5 ATA commands before each error. That may narrow down which drive is responsible.

I think I figured out which drive is responsible. I changed the cables and one of the drives is having issues. My problem now is figuring out which one - both work fine individually. Any idea how I can determine the port on the motherboard from Windows Disk Manager description for Disk 0 and Disk 1?
