USB transfers have the very annoying problem that they claim "100% done" even though it will still go on for 15 minutes or more (if a lot of data is being moved around), leaving you in the dark about the REAL time the transfer will take, and only displaying some random fake values instead.
Is there a way to fix that so that USB file transfers actually display the correctly estimated time till completion, instead of having you stare on the screen indefinitely without any idea how long it's gonna take?

Yes, mount your slow usb devices with the “flush” option. (See man mount)

Thanks, I tried that but it gave
mount: wrong fs type, bad option, bad superblock on /dev/sdb2, missing codepage or helper program, or other errorand dmesg said
EXT4-fs (sdb2): Unrecognized mount option "flush" or missing valueIt seems the flush option is only available for FAT filesystems.

What device is it? USB HDD?
You could try using "sync" option.

Yes, USB HDD.
Ok, will try "sync" next time. "Sync" doesn't reduce data transfer speed, right? (Assumed that the data is only written once in my use case, and isn't being reused for further reading/writing. I know it can for that matter cause life span shortening on flash devices). What I'm doing basically is a simple backup of large amounts of files to the usb hdd.
