If you receive an error from a command then please provide exact details; we cannot see your screen or read your mind. You will also need to research Windows and Linux separately as they have quite different file systems. For Linux you could start by looking at the df command.

Don't know about Linux. Here's what you can do in windows

Call GetLogicalDrives()
It returns a DWORD with bits (set) representing available drives : bit 0 for drive A, 1 for B, 2 for C ...

or

Call GetLogicalDrives(BufferLength, Buffer)
It will return a string of null-terminated strings of drive letters. (With one more null at the end)
like C:\<null>D:\<null><null>
