In this regard, how do I check if a disk is busy in Linux?
We can use iostat command to monitor system input/output device loading. It can be executed by any user, and is typically the first command used to investigate disk I/O issues at the command line. We can use iostat -xk interval to get the io status for our disks.
- HDDs have a delay because the read/write head needs to move to the right position.
- Seek time is where the hard drive positions the head over the right track.

dd is a command-line utility for Unix and Unix-like operating systems whose primary purpose is to convert and copy files. On Unix, device drivers for hardware (such as hard disk drives) and special device files (such as /dev/zero and /dev/random) appear in the file system just like normal files.
