what program??

[Dan]

I just had my secondary hard drive develope bad sectors for the second time...I've moved all the data to another drive.
Scan disc moved quite a bit of data, I was able to decipher most of it. But, I am left with almost 1,000 files that have an extension of ._dd
I have been able to open a lot of them in wordpad....many were just text files.
However, a lot of the files look like this: ?lñÅÉ&\€I§T1Æ ‡\«Æ$Ó'±J‹¬òÊ........
what program can I use to open these files so that I might understand what they are??
thanks
(I'm returning the hard drive for another)

thanks lobos
I know they are disk doctor files, but this does not help to read them.
what I need to know is how to open or read them.
anyone else have any help???
