I'm contemplating using the dd command below to rejuvenate data – 'bit rot' – on my hard drive (the drive is *not* mounted):
dd if=/dev/sdX of=/dev/sdX bs=128M conv=sync status=progress
I'm wondering whether I really need a backup? (what would happen if e.g. the process gets interrupted?)

I've not dared to pursue this approach any further. The slower approach of copying to another disk first and reformatting the existing NTFS file system with btrfs and copying back the data is safer and drops the Microsoft tainted NTFS file system as a bonus.
Note to self: when using #Linux do not ever again be tempted to keep the preformatted #NTFS file system on an external or even any drive, thinking it will be easier when using it on other systems. The ntfs-3g user space driver is slow as molasses! HORRIBLE!
