I hope this is the right sub-forum for this question.
Tonight I was helping my wife to back up her Windows 10 computer with Macrium Reflect. We connected her 2TB Seagate One Touch hard drive and launched Reflect. To our surprise, the Seagate didn’t show up on Reflect’s list of available disks. So we closed Reflect, unplugged the HDD, and repeated the process. This time the Seagate did show up in Reflect, but only as “Unformatted.” File Explorer didn’t list the drive, nor did Disk Management. I noticed that Norton Security had offered to scan the drive as it usually does, but then the dialog went away by itself within seconds without our taking any action. It’s as if the drive had existed for a brief moment, then vanished into thin air.
So I took the drive to my own Windows 10 PC and tried to do the same thing. After about a 30-second wait, the toast notification on the right, informing me that the One Touch had been detected, finally popped out along with the corresponding little jingle. However, when I went into File Explorer, the drive was nowhere to be found. Nor did it show up in Reflect or in Disk Management.
Now before you start formulating a diagnosis, here’s where it gets weird. I took the One Touch to my trusty Windows 7 computer… and the drive showed up right away in Windows Explorer. Macrium Reflect found it, no problem, as did Disk Management.
Next, I connected the Seagate to my Kubuntu tower, and that machine, too, found the drive right away and listed all its contents in the file manager, Dolphin.
A couple of notes FWIW:
- I tried a variety of cables to connect the drive to the computers, and this made no difference.
- The drive was purchased in April 2023. We had used it a number of times previously, without issue.
OK, now it’s time to diagnose the problem. What the heck could lead to this drive being found by Linux and Windows 7, but not by Windows 10?
