Apple issues fix for MacBook Pro SATA interface

Firmware update addresses drive speed issue in just-released laptops

In an apparent response to user complaints, Apple Inc., today released a firmware upgrade that it said fixes an issue with the drive interface in new MacBook Pros.

Apple said the MacBook Pro EFI Firmware Update 1.7 fixes a problem reported by "a small number of customers" using drives based on the latest SATA specification with the new MacBook Pro line, released this month.

But Apple warned that it has not shipped drives operating at the higher-speed specification, saying, "While this update allows drives to use transfer rates greater than 1.5Gbit/sec, Apple has not qualified or offered these drives for Mac notebooks and their use is unsupported."

Apple apparently downgraded the serial ATA interface on its most recent MacBook Pro laptop models, moving from a 3Gbit/sec. interface to 1.5Gbit/sec.

Most industry observers Computerworld spoke to speculated that the MacBook Pro line was experiencing higher than acceptable data error rates related to the 3Gbit/sec. SATA interface.

Apple has yet to respond to multiple requests for information about the reason for its SATA downgrade on the MacBook Pro.

Meanwhile, Macworld reports today that Apple has also issued an iMac EFI Firmware 1.4 Update for 20-inch and 24-inch early 2009 iMacs, which fixes problems where machines using ATI Radeon HD 4850 graphics cards would intermittently stop responding, as well as issues with waking from sleep while in Boot Camp.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
