Monitor disk I/O for specific drive in OS X
- by raffi
In my Macbook Pro, I have two internal drives and I've connected a third drive via USB in enclosure.
I am currently doing a secure wipe of the external drive and I was interested in seeing what the disk I/O was for that particular drive, but when I use Activity Monitor I only see the total disk usage for all drives combined.
Is there any way to monitor a specific drive's total I/O, preferably via a built-in or free method? I don't want to filter by process ID. I just want to filter by mounted disk.
