IMPORTANT: Because of the time-limited error recovery feature, this product is intended for server applications and is not recommended for use in desktop systems.
What is time-limited error recovery and why do I need it?
Desktop drives are designed to go to great lengths to protect and recover data, at times pausing for as much as a few minutes to make sure that data is recovered. Inside a RAID system where the RAID controller handles error recovery, the drive does not need to pause for extended periods to recover data. In fact, heroic error recovery attempts can cause a RAID system to think the drive has failed and drop it out of the array. WD Caviar RE is engineered to prevent hard drive error recovery fallout by limiting the time the drive spends in error recovery. With error recovery factory set to 7 seconds, the drive has time to attempt a recovery, allow the RAID controller to log the error, and still stay online. Designed for portable digital devices of all kinds including notebook computers, external storage, car navigation systems, digital audio to GPS systems, blade servers, and tablet PCs.
