Apple has just released Hard Drive Firmware Update 2.0 to its Mac users.  The firmware update "reduces certain infrequent noises  made by 7200-rpm drives."  The new firmware ID is 0007APM2, for those curious.

Apple claims that the issues are confined to the new MacBook Pros it began shipping in June (13" and 15") -- but it can't hurt for those who purchased the 17" MacBook Pro in January to update as well.

Another fix also came down the pipe for Mac users.  All unibody Macs and Macs shipped in 2009 likely use the Broadcom chipset for Bluetooth wireless.  The chipset had performed poorly, according to some, leading to difficulties using Apple's wireless mice and keyboards.  With Bluetooth Firmware Update 2.0.1, various bugs are fixed and the wireless performance is increased.

While its always disappointing to see hardware issues escape pre-launch quality testing, it's good to see that Apple is at least trying hard to solve some of the hardware issues on its Macs.  Now if Apple can figure out a way to fix the display problems that some users have experienced.
