PROBLEM:
I have a USB flash drive that I keep connected to my computer all the time as a second hard drive. I recently started getting random notifications that it was't properly ejected before disconnecting (when I wasn't disconnecting it). Afraid it was dying and needed to be replaced, I attempted to back up the data onto another drive. Every time I try to transfer data off of it, it disconnects, then immediately reconnects. Thus, I'm unable to back it up.

ADDITIONAL INFO:
I'm able to transfer data ONTO it just fine, it just won't let me transfer data off.
Additionally, I'm able to access/view/play all of the files, so the contents don't seem to be corrupted.

SYSTEM INFO:
13" MacBook Air, early 2015
macOS 12.7.2 (no available software updates)
Flash drive is Samsung brand, probably from around 2016
Plenty of free space on the flash drive and all attempted back-up drives

TROUBLESHOOTING SO FAR:
Used other USB port
Reboot computer
Tried transferring to internal HD, external HD
Reset SMC
Reset NVRAM
Executed sudo killall -STOP -c usbd in Terminal
All appears fine in Disk Utility (first aid, verify)

Any other ideas out there for how I can get this data backed up?

Do you have other USB devices connected to your MBA? Disconnect everything else and see if the problem persists. If it does, attach the flash drive to a powered USB hub. If it still disconnects then the 5+ year old flash drive is failing.

I did try it without anything else connected, and it gave me the same issue. I got the idea, though, to try using my wife's Windows computer. It gave me the same issue there too, but to a lesser degree (eventually). Between being able to at least start transferring data and the fact that Windows provides a "try again" option when it disconnects (as opposed to Mac's "it failed, too bad" approach), I was able to get it transferred onto another drive. Now time to get a new flash drive. 😅
