i have a WD my book 2tb external HD.last night i was deleting a huge number of files (18 GB that i have extracted from window7 disk).i came up a error about some corrupted files.the external HD froze and all drives vanished from the explorer. now today after plugging the HD ,two drives were giving error; "Location is not available P:\ is not accessible. The file or directory is corrupted and unreadable." .chkdsk doesn't ran on these drives.i am hesistant to use fixmbr and fixboot option (i fears that it will affect other drives also).after trying some partition recovering softwares , "ACTIVE partition recovery " shows all files and folder intact in the affected drives but how do i recover the partition. i don't know much about fixboot option.in both drives i got recommended option as "do not fix boot sector.PBS matches CBS and both look valid" please help!
