I believe that this task would be OS specific and so would defer from OS to OS.

In Windows, you can use one of the following methods -

Use QueryDosDevice to list all the device names in the system.
The device names listed would be something like \Device\HarddiskVolume1, \Device\Floppy0 etc.
From this list you can check that if there is no Harddiskxxx, it means there is no hard disk in the system.

Use CreateFile to open physical drives like \\.\PhysicalDrive0, \\.\PhysicalDrive1 etc.
Check the return value to ensure that none of the disks exists.
