Thanks.... have you ever had the drives oriented on their sides or vertically for a sustained period? I wasn't around for the "eBay Scam".... hot/stolen devices? BoltPrime is an "All In"/Lifetime Bolt. BoltBack is a monthly, so far. I can't decide if I will keep BoltBack for a year or not. I've upgraded BOTH with 3TB Toshiba and 4TB WD drives respectively, and have the original drives stored away should they be needed. BoltBack and BoltDonor were purchased on eBay as "Parts Only" machines, both from July 2016 manufacture. They were returned to the store because they got caught in the database switchover and say they can't find Cable Providers for ANY zip code. I got one fixed. I will get the other fixed too.... eventually. I will likely resell one or both at some point. I was going to hack the case on one of the extras, but may not now that I have decided to simply go for a new or off-the-shelf chassis design to house BoltPrime and the 8TB WD Red drive.
