Both backup devices died within days of each other.

We use 2 Western Digital DUO devices for backup... swapping them out every other day.

They both, all of a sudden, appear to not work.

All I get is a solid ON light.

It would be a coincidence for both to fail at the same time, but hardly impossible.

Can you connect either of both devices to a different computer?  Do they start?  If not, both have died.

Insert boot device and open pc in safe mode, try to format them with windows format settings to save them.

Also, if you've been swapping drives without unmounting them you may end up with problems.

Try cycling power on the dock/device used to house your drives.

And be sure to unmount devices before swapping them.

it may have been a power surge that shorted out both drives. are they shown up in computer management ?  electronics may work but if the drive is not spinning up then they are probably dead, try a different usb port. or use a tool to clean up the old drivers on the usb ports. Down load usboblivion from   This is a portable app that does not install but it will clean up old drivers tied to the usb ports, which some times prevent new device plugged into the usb ports from being detected.

I grabbed both devices and pulled out the HDs.  Each has two (RAID 1).

Both drives spin and are detected on a W10 machine.

These are used one at a time... I can't fathom that both have died at the same time.

I am going to look at the server as the issue.
Sheldon LivingstonConsultantAuthor Commented:
I took the devices back out to the customer and tried 3 USB ports before it was recognized... going to see if it backs up tonight.
JohnBusiness Consultant (Owner)Commented:
tried 3 USB ports before it was recognized   <-- There may be some issue with the controller software / firmware that has occurred
Sheldon LivingstonConsultantAuthor Commented:
Controller software / firmware of the server or backup device?
JohnBusiness Consultant (Owner)Commented:
The disk device if you can update that.
Robert RComputer Service TechnicianCommented:
when you plug a device into a usb port I would wait a minmum of 30 seconds to a minute to ensure the device is detected and has a chance to install the drivers tied to that usb port.  Or if you need to clean up the drivers previously associated with that usb port ie using the tool I suggested previously. usboblivion

I moved the devices to a third USB port and it has worked for the last few days.
Robert RComputer Service TechnicianCommented:
maybe the third port provides more power than the other ports, some ports do offer more power, in a pc usually the back port provide more power. Or it may be the ports are dying or lastly there may be other drivers associated with the other ports and you need to run a cleaning to to unassociate drivers for devices you no longer plug into the particular port.
