For some testings, I need to access something like /dev/sda in my program.
But I can't do this on my own hard disk drive. You know why :D
Is there a way to create /dev/sdb using RAM or a file on another disk? I just need it to be there, and act like a disk while I'm using it, no matter what.
I know I can use virtual machines for this, but that invloves installing a linux. That is time consuming and is not so elegant.
