long story I have an USB drive to copy data between Mac, Windows (personally I don't own any) and PS4 - it is exfat formatted. Recently I noticed my Mac would freeze when I plug in this disc - also there is a directory in the top hierarchy that I could not open. Since this drive moves around a lot I suspected an unlucky disconnection caused corruption. Checked the drive and the only partition with disk-utility "first aid" - which report everything is fine. Despite this in the system log there are plenty of I/O errors. Looks like I need to trash it. But I sure had loved it if my mac gave me any warning that I was using a bad drive (I kinda forgive the PS4 that she didn't warn).
So for the future what check should I use?
I see that there are older questions discussing a similar questions, though they are 5 years old and also some of the link tools are dead now. Also this question is not about data recovery, but how to asses a drive.
tl;dr What program (on mac) can I trust to check my discs?
