Harddrive Needs formatting? after 4 months of use, worst hard drive i've had

hi Joe, i’m having a very similar problem on a My Book 3.0 1 terabyte

partitioned into 687.37 gig & 244.14 gig

was using it for 9 months and just today, after not using it for like 2 weeks, noticed the drive not recognised, and after disk management, like you mentioned, it says the 2 partitions are now RAW

what is this RAW and how do i recover the partition information and my files?

i have the latest testdisk, partition magic 7.0 (rather old), 

none of them recognise this problem during the scanning.

i have recuva as well. and also “find and mount” software.

anyone, please help?  how do i get out of this RAW ?

want my files back … thanks!
