Hi,
Just a word of warning from experience on this...Thought I'd lucked out too in a similar situation. Everything seemed to work fine.
I loaded it to try to max it out and it seemed to be fine....UNTIL..I actually tried to access the files...It basically makes all the folders and possibly files appear as if they are there including the name and "space" changing. However, when going to access the files, the folders were actually blank and many files were corrupted with loads of jibberish instead of the correct info. In fact, when trying to delete the stuff that was now junk, it will not delete. I can put a few gigs on it ok, but that's it. Now, due to the "taken" space (which isn't real) I don't bother because I cannot count on the info not being corrupted.
Everything about what I bought seemed on the up and up including seller ratings. I've since learned how they up those ratings from supposed buyers. Also, even I gave a good rating due to fast shipping and the product seeming to work well. It wasn't until I tried to "prove" I got a good one that I realize how this scam works. I'm out about the same you are because of it.
So keep this in mind if you try to access the files (all of them), and they aren't there. Also, don't be surprised if you can't access new things you thought were writing including pictures or any other data including downloads.
I hope this helps.
