Problems with external HD after Big Sur upgrade
Hi all,
I have an external 1TB sandisk Ssd hard drive. I use it on may MacBook Pro 13" year 2016 because my hard disk is too full.
After the Big Sur upgrade I have a lot of problem to read it. I try many time before Mac can see the it and also when is seen it is very slow or crash.
I have tried to initialize it but the procedure fail because Mac can not deactivate it probably because is in use some where.
I don't think is a device problem because on windows PC is working with no problem.
Thanks for your reply
MacBook Pro 13″, macOS 11.0
