Some MacBook hard drives contain fatal defect, according to report

We've been hearing vague rumblings about potentially flawed MacBook hard drives for a day or two now, but a report from UK data-recovery firm Retrodata finally backs up all the noise with some hard data -- according to the company, revision 7.0.1 Seagate drives manufactured in China have defective read / write heads that can become detached and slide across the surface of the platters, making recovery impossible. Apple says it's only received "a few reports" of the problem, but Retrodata says the issue is severe enough to warrant a recall. MacBook users will want to fire up Apple System Profiler ASAP and check under the Serial-ATA listing to see what kind of drive they have -- and probably start backing things up, just to be safe.
