Altering USB disk format to Ext4

Just a heads up for anyone else doing this - its slow or I did something wrong (Linux moron here ). I finally got round to reformatting the 6TB USB HDD I use on Kodi and adding the code to check it on boot:

Code: /storage/.config/system.d/[email protected]/fsck.conf

[Service]
ExecStartPre=-/usr/sbin/fsck -T -M -p -t ext4 %I

The only problem was the time taken to copy the c4TB of data from disk 1 to disk 2. It took over 26 hours. Started off really well telling me it would take c6 hours but it got slower and slower ending up at 40MB/s. I had done transfers using the exact same equipment, same data under Windows (NTFS -> ExFAT and NTFS -> NTFS) and that took c10 hours.

Its done now so I should no longer need to plug into a Windows PC and run chkdsk. Transfer speeds using SAMBA and FileZilla over my LAN look about the same as when the HDD was NTFS.

The change to Ext4 seems to have worked. Kodi "froze" last night. Powered off and back on and the disk was fine, no problems.
