Fix coming for MBP HDDs
A software fix is enroute for MacBook Pro owners encountering frequent hard drive stalling, according to Apple spokesman Bill Evans. The problem affects 7200rpm, 500GB drives, freezing a Pro for several seconds before allowing normal operation. Stalls are typically preceded by a beep, and several clicks indicating overworked reading mechanisms.
Apple has not explained the cause of the problem, but a source at Other World Computing has attributed it to Seagate's Momentus 7200.4 drive. The model uses G-Force technology to provide shock protection, but in a Pro this doubles on top of existing technology, potentially triggering rapid spinups and spindowns. It may also shorten the overall lifespan of storage. Systems equipped with 5400rpm drives are believed to be unaffected.
