external hard drive does not recognized

[lladam]

Hi,
I have a 2T Fantom external hard drive used for a few years. It was good, but just can't be recognized today.
The phenomenon is:

My laptop's USB port all good for other USN key or hard driver;

This HD can't be recognized by two of my laptops one Win7 and one Win10, but it is starting when plugged in (I heard the starting noise) just not shown in computer;

The HD was fully filled with ~300M free space left only.

The Disk Management tool doesn't show the HD either.

Thanks
Adam

Hi, welcome to the forum.

So this external hard drive isn't working with your Synology NAS? Or it is but the shared folders in DSM aren't available via WIndows file sharing on your PCs?
