| You'll notice in the tooltip of the hard drive that it has been assigned an address (that shortened, alpha-numeric string). You don't have to remember that, it's just there for reference. Next, open the screen's GUI and type `df`. This program lists all present file systems and their current mount points. Among them you'll notice one that's only known by address (unlike the ROM and temporary file system). That should be the address you saw in the tooltip, earlier. | You'll notice in the tooltip of the hard drive that it has been assigned an address (that shortened, alpha-numeric string).

| What we want to do now, is to assign a name to our hard drive, so we don't have to reference it by address all the time. Run `label` to get the usage information of the labeling program. We'll use the `-a` option here, but you could also label it by providing the path to its default mount point in the `/mnt` folder. | What we want to do now, is to assign a name to our hard drive, so we don't have to reference it by address all the time.

| We can now mount the hard drive while referring to it by name. Type `mount <label> <path>` to mount the hard drive with the specified label at the specified path. Hard drives can be mounted in multiple locations, so doing that will not invalidate the default mount in the `/mnt` folder. | We can now mount the hard drive while referring to it by name.

| Autorun scripts get the proxy of the storage medium they're on as their first parameter, so we can use Lua's varargs syntax to access it. We'll pass that to the `fs.mount()` function, which you find documented in [[api:filesystem|the file system API]]. | Autorun scripts get the proxy of the storage medium they're on as their first parameter, so we can use Lua's varargs syntax to access it.
