Thanks

i ran the WD Align to check the HD,it says already aligned. then i ran another software which is WD Data Lifeguard Diagnostic.i choose to do the quick diagnostic,then it shows FAIL. is it indicate that my HD is totally damaged? and if i RMA the HD,is it better,or i can fix it by my own?
another question is,i already formatted the HD, is there any method to retrieve back my files instead send it to manufacturer?
You can try using data recovery software like Stellar Phoenix Data Recovery, etc.
There's some free one out there using Hiren's BootCD bundles.
You can try to wipe it using the WD included diagnose software, can't remember what's the program's name though. Something to do with disk wipe.

i can backup all data from both partition.
but cannot format the raw partition.
maybe need to delete all partition and make new partition, im not sure, i will try later.
You can try disk wipe software (Low Level Format is one of it) to wipe the disk clean to manufacturer default settings then start align/create partition from there.
If this fail could means the surface is damage beyond repair or the controller itself is fried/corrupted. This is the EOL, nothing you can do other than RMA or paper weight.
