anyone.. ?

it was like this, my friends got Seagate HD (80G) and have two partition on it.he used it as extrenal storage (USB). suddenly, one of the partition can't be read/access at all, the other one can. so he send it to one of the IT shop (at Lowyat - Hypermarket something) to recover it since he need his project data on it.

To make it worst, after he send it to that shop... both of the partition can't be read anymore and the disk now mark as DYNAMIC Disc (Unreadble) when used Disk management.

so, question is, is there any way to recover that partition? if does.. how to do it?

thanks in advance.
