i have a SATA hard drive that will not mount - when i connect it to my imac it spins, does a few clicks, then goes silent. i've tried a number of different enclosures, cables, etc., but nothing works. i want to recover the data on it since it houses my 200GB aperture library that i didn't back up very well. can anyone recommend any data recovery service? obviously, i'd prefer something that won't require me to take out a second mortgage...but if any of you have had good experiences with a specific company, i'd be interested. thanks!
