I recently dropped my 1TB hitachi external drive and now the arm just joves back and forth. Need to get my data out as I have a lot of important info. Need help. Here is the video link I made to show you what happens.

Most likely the heads have been damaged due to the fall & will need to be swapped with a compatible donor.

If the data is important then why did you take off the lid/cover?
You should seek a dr professional rather than risk your important data.
The platters will now be contaminated. Profession equipment is required ie cleanroom etc + experience & knowledge.
This will probably cost you more to do a recovery now but if you stop trying DIY & seek a pro then they should hopefully be able to get your data recovered.

Do you recommend any particular company with great prices plus very reputable to recover my data?

You can forget 'great prices' as the drive was already opened, in my opinion...

I agree.
However, contact member jono-ats he 's in Atlanta, he might be able to do this for you for a fair price.

OTOH, this looks like chances of media damage are high, IMHO.
