IBM SATA drives in xSeries and BladeCenter servers can become bricks due to a firmware fault. A fix is expected later this quarter.
The IBM SATA drive hang or drive note states: "After a power cycle, the SATA drive is no longer available and becomes unresponsive. Data may become inaccessible due to the drive not responding."
