I got a 2T Western Digital portable drive as my main storage for my MacBook Air, with encryption enabled. Currently I used ~300G out of 2T, with maximum read/write speed of 30 MB/s (USB 2.0)
I just purchased a AirPort Extreme and found that it cannot read encrypted drive. So yesterday, I plugged my 2T drive and select "Decrypt".
Activity Monitor showed that my mac constantly read/write at a speed of 15 MB/s (which I believe the decryption process is running).
Today, after nearly 12 hours, the decrytion process still running (as shown in
Activity Monitor), and the total read/write is already 500G each. How come it's possible?
Also, I can "Eject" my drive without any problem. But, when I tried to plug it back, my mac start reading it at constant read/write speed of 15MB/s again.
How can I abort the decryption process or figure out what is going on here?
