"Apple MacBook Pro firmware fritzes third-party HDDs
Fast Sata drives fail post patch

Apple's firmware upgrade, which restores the 3Gb/s Sata link
speed to MacBook Pros, has also caused some 'unauthorised' hard
drives to fail.
An Apple Discussion board thread has 65 comments about the
issue, which may occur when the Apple-shipped drive in the
MacBook Pro is replaced with a third-party drive and the fast
Sata firmware upgrade is applied.
One poster, Ian Burrell, first noticed the issue with a WD
Scorpio Blue drive. His MacBook Pro froze randomly and he
suggested that there were intermittent data errors.
Unfortunately, there seemed to be no way to revert to the
previous firmware and so recover from the problem.
A poster called Whaleface, with a WD SCorpio Black, wrote: "No
disk access can happen at all for 20-30 seconds, then usage
spikes, then no disk access at all."
Another poster found his Intel X25-M solid-state drive worked
before the update but not afterwards. Andrew Myers wrote: "I
would like to add that I'm experiencing the same thing as the
above users. I am using the Intel x25-M. This is terrible, the
laptop is near-unusable."
Some users report their Sata II drives work fine after the
update. Others say they are having problems with stock Apple
drives. One poster reverted to a 1.5Gb/s Sata drive and the
problem went away.
Apple Store contacts are variously reported as saying that the
company warrants its software - and firmware - to work with
Apple-shipped drives, which happen to be 1.5Gb/s Sata units in
the MacBook Pro, but not with uncertified and retro-fitted
drives, such as many of those listed above.
Poster jlamarp wrote that Apple Technical Support told him:
"Apple is not responsible for maintaining compatibility with
third-party aftermarket hardware with their firmware updates."
Indeed, the blurb accompanying the recent Firmware 1.7 release
says: "While this update allows drives to use transfer rates
greater than 1.5Gb/s, Apple has not qualified or offered these
drives for Mac notebooks and their use is unsupported."
Apparently, Apple "Geniuses" at Apple retail stores may be able
to roll back the firmware upgrade if there was a problem during
the upgrade itself, but not otherwise. Apple was not immediately
able to comment directly on the issue. ®"
Het herinnert me er wel aan waarom ik toen zo'n "lelijke PeeCee"
