Re: rsync seems to hang when asked to update backup of large disk

Yep. I use gparted quite a bit, though for some (not all) tasks lately I've found gnome-disk-utility
slightly more user-friendly. And for USB sticks I generally use mint-stick tools simply because they
are quick and relatively good at telling you what disks are what i.e., don't have to remember which
/dev/sdX to use. And they only offer the USB connected drives with both path and the manufacturer
name and capacity. I find that helpful in avoiding "oops, wrong drive".

I swapped disks yesterday and then formatted new one ext4. Then copied files from home repo of files.
About 2 TB, but it went faster than when ntfs / fuseblk.

Best, JN
