I just recently installed all new pci-e flash/ssd hard drives to replace my disk drives. I planned on using the disk drives as backups as I have the trays in my mac pro (3,1 mac pro 8 core maxed out ram osx mavericks). So one of the drives, which has a ton of samples as well as my entire itunes library of .wavs from hundreds and hundreds of cds I use to reference audio mixing. I was in the process of copying them to a new destination drive. But in the middle I kept getting -36 errors and then all of a sudden it would either cease to be recognized at all, or all the folders would be empty. It's worth noting that the file transfers were huge, and also, the drive itself used to be me my scratch/project drive and it's been like 7 years of heavy use. So I did some googling and downloaded a program to do the S.M.A.R.T. test and it failed (also failed in disk utility as the smart status is not verified). When I restart my computer it shows up again and all the files show up, and some of them can even be loaded such as wav files. But some seem to be corrupt randomly. Any time I try to copy files, it freezes quickly after being very very slow for like 20 minutes. So my goal here is just to get the files off, I don't care to save the drive. Once the files are off I can just buy a new drive, which I was gonna do anyway. I just gotta get there files off. And since the drive is not fully dead (yet), I don't believe this warrants paying the super high fees of data recovery. I'm hopeful someone can guide me in the right direction. Below I posted all the specific results in case someone is super technically fluent and it can help them solve my problem.
