Summary: There is some info label on the drive about using some WD alignment software if the drive will be used with XP. I am only using them with Mac and Win 7, so that does not apply to me.
Pros: Great price for 250 Gb notebook drive. I received 3 and they all work, used them in in Mac computers, and a couple PC notebooks, switching them around, reformatting, copying files just to make sure they all performed OK.
Summary: Works fine as a cheap drive for consumer laptops. I've pulled a bunch of these dead drives out of my friends' laptops, but it's tough to blame the drive when the laptops are constantly being carried around and dropped.
Summary: I got - no joke - a 'Catastrophic Failure 0x8000fff' from Windows Update. WD had mentioned you needed Intel Matrix drivers 9.6 or higher. Turns out the lack of driver support for AFD in the stock Vista/Dell drivers means Windows Update fails BADly. Only one problem - the latest version of the drivers (10.8) do NOT support the very popular ICH8 chipset. v9.6 DOES, but it's almost IMPOSSIBLE to find.
Summary: Markenfestplatte zum günstigen Preis. Die Platte wurde am 04.09.2013 gekauft. Daher kann ich noch nicht viel über die Haltbarkeit schreiben aber bisher läuft alles fehlerlos und sie wirklich sehr leise. MAN HÖRT WIRKLICH KAUM WAS !
