I wonder why. i had this WD 2tb ext drive for more than 3 months now and i used this last night and it was still ok. i've used about 220 gb on it but now there's an error when i connect it to my macbook. the disk you inserted was not readable by this computer. is there a cure to this? i never pull out the usb w/o eject, i always eject it properly before pulling out the usb. ---------- For any help, thanks.
