I have been using the same Seagate 4TB USB harddrive on my Raspberry Pi for well over a year now and haven't had any issues, but after copying some films to the harddrive Kodi no longer appears to detect the harddrive and mount it, i have tried to manually mount it but the drive doesnt even show up at all. I have tried the harddrive on an old Intel NUC device i used to use and again it doesnt detect or mount the drive (which it used to work fine one), if i plug the drive into my PC however it works just fine!. Im wondering if Window 10 has altered the drive in someway for it to stop working correctly?

If i have it plugged into my Raspberry Pi and unplug the PSU of the harddrive then a message comes up 'successfully removed storage device, media_drive' but its not showing up in Openelec at all.

I have used the command dmesg to check what happens when you connect the drive, here is the log....

Code:

I guess the scatter-gather UAS driver is the issue, what on earth is scatter gather?

Any ideas why Openelec has stopped detecting this USB HDD??

hi, I have a similar problem with all of my external hard drives, I don't get the message in dmesg though. Have you been able to solve the issue?
