What is the difference between logical (virtual) harddrive and physical one ?

Question

and what it means when you say that you have logically deleted a file ? and how can you delete it physically??

thanks.

Answer 1

Physical drive

Refers to the actual unit of hardware of a disk or tape drive

Logical drive

An allocated part of a physical disk drive that is designated and managed as an independent unit. For example, drives C:, D: and E: could represent three physical drives or one physical drive partitioned into three logical drives

Hope this help!

Answer 2

one exists and one doesnt.

Answer 3

Under DOS - when a file is deleted - the first character of the filename was deleted from the file registry - but the file data still exists - thus it's logically deleted.  As long as the data doesn't get over written, it's possible to recover it.

Sort of like putting a file in the trash can, but not deleting it permanently.

If you over write the area of the disk that contains the file data, then the file is physcially removed from the harddrive.

Answer 4

think of it like this logical is imaginary and physical is real. cause thats how it works but thats not how your PC sees it. PC sees logical HDD as a second HDD when really you only have 1 HDD
