How to check the health of a hard drive
I replaced the stock Fujitsu drive in my MacBook Pro with a Seagate Momentus XT and I'm having all kinds of problems.
Specifically, apps will lock up for 30 seconds or so whenever anything accesses the disk, making the system all but unusable.
Interestingly, the same drive works great when it's connected through an external SATA-USB bridge, and the stock drive never caused any problems of this nature.
So while the cause of the problem is pretty conclusively narrowed down, my question is if there's anything I can do about it. Are there diagnostics I should be running? Settings I should be tweaking?
Or should I just return/exchange the drive as defective? And in that case, is an exchange worth pursuing or is it more likely to be an incompatibility than a faulty piece of hardware?
