I think we've figured out the isssues with rsync and the various options, and a good option seems to have been implemented and working for JN. But if you must know, I mostly use fdisk. I started using gparted a while ago when aligning disks to 4k boundaries was a pain with fdisk. I still use

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

looks to me the WD is more in need of reformatting than the Seagate, especially for 4k blocks. You could set the filesytem label with fdisk without affecting anything, but it wouldn't fix the 512byte logical blocksize the drive is reporting. Most modern drives now are 4k physical sectors, using

I recall reformatting the Seagate not long after purchasing. Got lazy with the WD, but will at some time do this (carefully!). Given the cost of disks today, if I value my time, I'll probably just buy a new one and format it right away then copy. Best, JN On 2019-01-07 9:59 a.m., Dianne Skoll

Thanks for this. I did some checking, and Raj's suggestion seems to be confirmed, though there are some aspects of the reported information that don't fully make sense, since both disks are USB external ones. The Seagate 3 Terabyte is a 3.5 inch with external power supply. The Western Digital

Ah that makes sense. I can (possibly) explain this behaviour, I have seen it before. By default, rsync will compare filesize and timestamp before deciding to proceed with a full file compare. Somehow your incarnation seems to think the size and/or timestamp differs, and is moving on to a

My script uses the -auv flags, so I see stuff going on. It was when this stopped for a very long time at a point where I did not expect that I though it had hung. I ran things again, though from a terminal, and when it seemed to hang ran strace -p and could see things going on (no copy, just

If it does the whole directory and then shows the output, it could seem slow. I wrote a perl wrapper that backs up a whole directory and then prints the output. Is seems slower than running rsync manually because there is no output until the end. On January 6, 2019 8:10:13 PM Peter Sjöberg
