2 Questions: I have seen a lot of people and threads having problems with 4TB 2.5" upgrades on their Bolt's here. I've only seen one long time poster that has a 4TB drive for quite a while without problem. (1) Have others here had success with upgrading their Bolt with a 4TB or larger 2.5" drive??? I'm trying to see if any reasonable number of people have upgraded their Bolts beyond the 3TB Toshiba drive that seems to work well, and gauge if it's worth risking trying to upgrade to a 5TB seagate drive. (2) If you have had success, can you tell us roughly how long you've been running the upgraded drive, how full/hard you run it, and what formatting tool/version/instructions you used to set it up? Thanks so much for any help!
