So I'm pretty good with the OS, but I am not so hot on the behind the scenes stuff, so advice involving Terminal, for example, would require very detailed instructions. I just put that out there because I searched MRoogle for this topic and there were many ideas involving commands like fsck (sp?) that went way over my head. But like I said, I'm good with the OS, been using Macs since my Dad brought home our first one in 1985 (it cost more than his car) never even owned a PC in my life, probably why I'm no good without a GUI. Anyway, here's my situation. I just finished a series of projects at work (over the past 2 years) and have amassed about 10 external fire wire drives. Most of them are G-Techs so we've invested a bit of coin into them. We have a break before our next project starts and I would like try to assess which ones are still healthy and which ones should be retired. I have tech tools (never used it) I also have Drive Genius 2. I ran an integrity test on one drive, it made a pretty graph but have no idea how to interpret it. Any help/advice/tips would be most appreciated. Also, all of them can be reformatted at this point. Oh, and they were shuttled around town on these projects. They were pretty well taken care of, but handed over to be used and transported by others, so it's not like they've been sitting on a shelf in my care for two years. Thanks in advance for your responses.
