Went to local Best Buy with my need. Geek Squad guy easily removed subject part. (After watching how easy it was, I might have tried to do it myself.) Went to shelf stock and selected plastic case. Very inexpensive, BUT...my part wouldn't fit. Then selected docking style instead. BUT...it cost $60. I bought it because he was being so nice and helpful. Later, I read on the box it is able to hold two of those parts. ( Hard drives?)
Decided it really was more than I needed to spend to accomplish my task at hand. Took it back to a different Best Buy store...and this guy tells me I should have used it to retrieve my docs and then bring it back. Told him I considered doing that, but felt I'd have to tell a lie to return it. Got my money back and was told to try a place called. Fry's . I've seen that store but never been in one. OMG...talk about being overwhelmed!
Sorry for making this short story so long. This store had no less than 25 versions of a case, but the one the salesperson opened did not fit my drive. (It is 2.5 but too 'thick') Finally he suggested one that has a piece to clip on with USB cable. Not pretty but it will get the job done for $9.99 plus tax.
All is well that ends well, they say. Not able to do the job yet, but I am hopeful. And happy that another Tugger received some useful information as well.
