[help - solved] Hard-drive upgrade on x60: head parking

Hi all,
I have a question that may sound silly to some, but that left me wondering: is the HDAPS feature of the x60 (and other thinkpad of the same generation) compatible with any 2.5" SATA HDD currently in production?
I am looking forone of two Hitachi HDD on different series: the 5K250 serie and the 7K200 serie.
Looking to upgrade from a factory 60Go ... XD
Regards,
Tam

HDAPS i'm guessing you meant the Active Protection System? If that's the case then yeah, basically it's just a combo of a device (gyroscope i think) and software. The software reads the device and sends a "park" command to the HDD which overrides all the other requests coming from the OS.
So yes any drive that supports PARK (ok ok, all HDDs except SSD i guess) will work just fine.

Ok, I get the technology involved.
I am wondering whether this is a feature that is generally found on any modern HDD in the 2.5" format or this is only on specific models.
I could not find any documentation from Hitachi GST about their possible lack of this technology (even though it is a former IBM production).

The accelerometers that are used for the APS system are on the laptop itself, not the hard disk. So any 2.5" sata hard disk that supports head parking (which should be all of them) will do. To give you an idea, most MFM hard disks from the 1980s supported head parking
There are some hard disks that also have accelerometers themselves (kind of an in-built APS function) -- not sure how they play alongside the ThinkPad one. I'd assume you'd have to turn one of them off...

PS: it remind me the time I found out about the technology called Radial used in the tyres and asked my mecanic if all modern tyres used it ....
