I have a Toshiba DTC810 external hard drive that was working properly for almost a year. Then, suddenly, yesterday I plugged the drive into the USB port and it wasn't working. I tried to plug him into a Windows PC and everything was fine.
Does anyone have a clue what could be the problem? My mac version is macOS High Sierra (MacBook Pro 2015) and the external hard drive was properly formatted before use.
Thank you,
Nemanja

Without more information one can only recommend generic steps.
Since it works on Windows PC, it is not the drive nor the cable.
1- verify if it is the USB plug, by plugin another USB device and see if it works
2- try the second USB plug on your Mac
3- Open Disk Utility in Application>Utility Folder and see if it shows there
If it does not show in Disk Utility, lets hope it i not hardware but it can be fixed by following.
