After an updated release of Intel's Matrix Storage Manager [v.18.104.22.1683] and chipset drivers for Windows, you experience unexpected system timeouts, lockups, pausing, or freezing. The following event is recorded in the System event log:
The device, \Device\Ide\iaStor0, did not respond within the timeout period.
The issue is the result of Aggressive Link State Power Management (ALPM) on the PCI-Express bus negotiating a lower power state for the link between the controller and disk when there is no activity. When ALPM works, disk requests are queued, the serial link revived, and the queued requests are sent to the relevant disk; this requires a disk that supports ALPM.
Searching for a solution yielded a number of possibilities.
Setting the value of:
as discussed by Derek Seaman did not resolve my issue.
as suggested by Paul's Computer Service was also ineffective. At the time I was running the latest set of drivers for my platform. Caveat emptor: the solution I outlined in this article worked for me.
When launching the Intel Matrix Storage Console and reviewing the disposition of a mirrored pair of Seagate SATA 3.0Gb/s drives, I noted the Serial ATA transfer mode reported as Generation 1.
SATA host adapters typically support autonegotiation, however, with the Intel ICH10R this does not seem to be the case with RAID enabled. Note: It does work with standard AHCI mode on this chipset.
Seagate drives ship with a jumper enabled for 1.5GB/s mode. One must remove this jumper to force the drive in 3.0GB/s mode.
