The first thing you need to do is access the drive. You need to somehow remove it from the computer, or at the very least, get to it so you have enough room to connect some cables, so it can be powered up and get the data off of it. Check youtube. There's probably a 90% chance that someone has made a video of how to do this. Later, when I have more time, I'll post an easy way for you to try and recover what's on the drive (providing it still works).
How to transfer data from external hard drive?
I have an external hard drive (Drobo) that has about a terabyte and a half of music all loaded onto the hard drive through burning cds from Apple Mac Mini. Unfortunately, the mac mini suffered a catastrophic crash and I cannot retrieve data from it. I want to buy a new mac mini and bring the library of song titles and artists from the hard drive, but not the music data files (too large for the mac mini internal hard drive. Anyway I can accomplish this?
