At > least I am sure that drive inside has standard ports. I've had very little problem with USB drives, I've been using KDE Neon for a few years now. Sounds like you have a hardware fault especially as rsync doesn't work either, I use rsync on a daily basis to check and copy thousands of files, never have a problem. If that was my system I'd probably wipe the drive with nwipe (ShredOS) https://github.com/PartialVolume/shredos.x86_64 , it will give you an idea of throughput and will check every block with verification. if that bombs out with an I/O error I'd test the drive on another system with a different USB controller in order to isolate the problem. If it's the drive scrap it, it's not worth the hassle. -- You are receiving this mail because: You are watching all bug changes.
