My 4TB SSD drive used as a data drive became non-accessible. The same thing happened 3 weeks ago. I formatted it and copied the backup to it. I started this recycled 4TB but the problem happened again. It appears that I should let it be RIP.
My question here is that the Firefox browser appears working even its profile is in the 4TB drive. I wonder why Firefox does not have any problem accessing it while I cannot by using Windows Explorer.
