If you inspect the heads and only the top surface appears to be damaged then you could try, but with that type of damage all surfaces are probably dirty now. When a customer opens a drive and ruins the top surface you have a better chance of recovery than a case like yours with catastrophic failure. Here is an example of a 3TB DM recovery with the top surface damaged because it was shipped with the top cover removed. Over 13,000 files with no errors recovered and 2700 videos that could still be played, with defects.
The DM series seems to be the drive of choice for customers to open and just "have a peek". Some we have recovered without removing the top head, but the one I have mentioned here had to have the top head removed from the donor HSA before we could perform the recovery.
Thank you, Larry.LarrySabo":2pmd1i9d said:Wow, David. Nice job!
I'm sure you will get plenty of arguments if someone posts "the best". We use a 20x-40x for viewing heads and a 10x-30x for flash repair. You can purchase them with .5 and/or 2x barlow lenses to make them have more or less magnification. One scope could do both jobs in the beginning but flash repair can be a dirty business so you'll eventually want more than one. Amscope makes reasonably priced professional and educational microscopes. If you have a bigger budget you might look at Meiji Techno.Freakazoid":2w9w3tr6 said:What is the best microscope to control your head with? and how do I see if a head is good or bad / dirty
OK, if you are doing logicboard repair then you already know things can get messyFreakazoid":3664kc9w said:Yes I know.. same if I ask what you recommend.. I think the one I have is 7x-45x with .5 Barlow lens. I use it for MacBook logic board repair.. should I have over light, light on side or under light ?
