My External hard drive does not show up in my XPS 2019 Win 10 64bit. It is Seagate backup Plus Slim+ 2TB.
I plugged the hard drive like the usual thing to do, copying file, suddenly the speed was slowing down to the point where file was took longer, so I plugged out the hard drive.
The next day, I tried to plugged in, nothing show up.
I checked in Computer Management, Disk Management and Device Management, there is nothing showing up and did the disk part and list volume or list disk, also nothing show up.
I did check in my device manager, yes there is 'Seagate BUP Slim SL SCSI Disk device' under disk drive but here is the thing, I did all the solution out there in the internet, update drive or uninstall device but nothing is work.
Another thing is, when I plugged in the hard disk, there is a usual USB beeping sound but after a minute or two, another USB beeping sound of plugging out.
I recently installed an external hard drive and some similar problems. Turn your computer off, then unplug the USB cable, and then the power to the drive. Restart your computer, plug the power into the hard drive, wait 10 seconds, and then plug the USB into the computer. This clears the hard drive buffer. See if the drive shows up in disk management. Before formating, turn off your antivirus. I had no problems once I did that.
