This is a solution I have used in the past and it has worked. It's a Seagate Recover utility for end users.

If the data is absolutley critical and very valuable, you can send it to Seagate and they are very good at recovery as well. It gets a little pricey at $800, but I too have had to use that as well for mission critical data I could not afford to lose.

Hello

Yes, you can leave the device plugged in, you do not need to unplug it if you turn off the computer, do remember to safely remove when you plug it out though.

Kind regards

SOURCE: I have a Seagate Expansion Harddrive 500gb. When

The external storage device has several major components:
* USB cable
* external power-supply
* disk-drive inside the enclosure
* USB-to-disk-drive adapter inside the enclosure.
Try a different USB cable.
Try a different USB port on your computer.
Try a USB port on a different computer.
Take a multi-meter, and measure the output voltage/amperage of the power-supply,
and compare with the specifications on the label of the power-supply.
Open the enclosure, and remove the disk-drive, and attach it as a "slave" drive in a desktop computer, to see if bypassing the USB-to-disk-drive adapter bypasses the problem.
Look at the label on the disk-drive, for manufacturer, product-number, serial-number, and manufacture date. Access the manufacturer's web-site, and use "check warranty status" to see if the warranty still is valid. If so, the drive can be replaced, at minimal cost to you.
Buy a new, compatible, disk-drive, and install it in the enclosure, to "revive" your external storage device.
Search online for a professional "data recovery service". For a significant fee, they can repair your disk-drive, just long-enough to copy your files to a new disk-drive.

be sure power is supplied to the HDD, if and inter HDD change the cables, if is external check the USB cable and see if you need a complementary power brick or a second USB to power it.
