So I own a “WD 2TB Elements Portable External Hard Drive” which I use as a backup drive to my computer. I have it hooked into my PC 24/7 and transfer stuff back and forth between them on a daily basis and have had absolutely no problems. It’s hooked up via USB 3.0 connection so it’s also pretty fast as well.
I took the drive over to a friends house to share some content and for some reason after plugging it into his computer I could see the files on it and explore the drive just fine, but the moment anything was transferred off it the upload/download would start at 30mbps and then immediately drop down to 0mbps and completely stop. Selecting different files or even moving one small thing at a time didn’t work as nothing on the computer, not even a 10kb text file could be transferred, and using different USB ports didn’t help at all, neither did multiple restarts. The weird thing being, I could transfer stuff off a 32GB flash drive I also brought just fine.
My friend told me the drive seemed to be dead or was in danger of dying but taking it home and replugging it into my computer the drive is working just fine and I can transfer stuff on and off it just like old times.
This is just a guess but it might have to do with the file permissions. I don’t really know how this works exactly so hopefully there are some computer gurus here but the drive might not recognize the host machine so is refusing even read permission.
Again, this is also just a guess, but you might be able to go into the properties of the drive (rt click, properties) then the security tab and add the current user of the host machine to the list of authorized users. That’s probably something the host admin would have to do but presumably that’s also your friend.
