Copy USB data to new USB device

[Smokey613]

I recently setup my new RT-AC86U. It’s working great so far with one exception. sometimes on a reboot the 16G USB drive will not be recognized. I think the drive may be flaky. The usb stick was formatted ext4 using the amtm utility. How can I copy my data from the old usb stick to a new one? Am I forced to redo my setup from scratch for all my add on scripts I am using?

Thanks! I did not do a Google search, only a search on this forum. I guess it was too early and I had not finished my first cup of coffee.

Lots of good and free utilities out there but i like win32diskimager. it allows you to create exact images and resize to larger usb devices.

Or just plug both USB drives into your router and use cp command to recursively copy all directories and files across? No fussing about with third party tools that way.

Using tar (or DD) ís often a slightly better alternative to cp.

Good point. tar probably best to transfer and preserve permissions. I think dd has the potential to create problems with disk partitioning.

Use the -a switch for cp

Fat32 doesn't contain much in the way of permissions/attributes. Op stated the drive is ext4 formatted, so it's irrelevant anyway whether or not it works for fat32.

I used this software to clone my usb drive to another one. Worked great. Thanks for the info! I was also able to reformat the usb stick I took out of the router back to FAT32 using this software.
