I am running Windows 8 Pro. I have a 3TB Seagate USB desk drive which does not show when I boot up. I can unplug the USB then plug it back in again, at which time it shows on my "Computer" drive list. My motherboard is Gigabyte Z87X-UD5H ATX LGA1150 Z87 DDR3 3PCI-E16 3PCI-E1 HDMI CROSSFIREX/SLI SATA3 USB3 Motherboard. Is there a reason for this, a setting adjustment I can make?
Thanks, TonyT. Using Device Manager I checked for new drivers and found none listed. However, I went to the motherboard manufacturer's web site and there were a slew recently added. I have updated them all. Unfortunately the issue remains. The drive is invisible at the time of booting, only being picked up and listed if I unplug it and plug it back in again. I have tried different USB ports. The drive is pristine, as is the USB cable. If it was the drive, the USB port, the power supply or the cable, I don't think it would be recognized and function perfectly every time after a reconnect.
When it is working, is it actually working as a 3.0 device? I mean, can you move or copy files at 3.0 speeds? Most motherboards with usb 3.0 ports have just a couple 3.0 ports colored blue and the rest of the usb ports are usb 2.0. Be sure it's connected to a real 3.0 port.
Yes, it is connected to a USB 3 port. I can see this issue might slow things down but my problem is the drive does not show at boot up. I have another 1TB Touro portable drive also connected through another USB port and that shows no problem.
How is it listed in Disk Management. Mine shows G:\ WD Unlocker drive it does not show in the Device Manager but shows in disk management as unallocated space. When I unlock the G:\ drive with a password then mine show in both disk Management as H:\ and in the Device Manager as WD Drive Management Services.
Thanks Tony. I had a good read through all of where the link took me. When I go to Device Manager and check the USB port where the drive is connected, it shows an exclamation mark and an error code 10 under properties.
What the articles you referred me to suggest is that a Code 10 points to a driver error. As suggested, I updated the driver through the Device Manager facility and also checking at the manufacturer's web site. There is no other driver available. I uninstalled the driver and reconnected the device. After boot it is still not seen. The driver details shown when I click on properties:
First see the Microsoft support article related to this issue. Others are found here.
In general, Code 10 often means, unfortunately, that the drive has failed. If the drive shows the same problem on another computer, try connecting the drive via 1394 (Firewire) if possible. If that is not possible, please replace the drive.
