I'm formatting and testing 6x new old 4TB drives, one drive on the motherboard sata connection and one using a USB 3.0 sata cable. I was running WD tools on the MB drive, and disk management on the USB to format that drive, and all seemed dandy, then I tried to upload the .png of the Crystal disk info results, not recalling where CDI puts those I did my lazy usual and tried a search of "my pc" for the saved image in the upload dialog box and things kind of froze related to the dialog box and I closed it. About this time the drive that was being formatted by disk management, poofed from that window and it refreshed. USB/Sata adapter is showing traffic as expected during a format and I can feel stuff going on with the drive, but nothing sees it. Format on 4TB takes 8 hours, is this normal or should I stop and restart it, which would also allow me to swap in the next drive on the MB connection?
