If your in Single User Mode by booting with -s you can mount your USB thumb drive like this.
Boot into Single User Mode
without the USB thumb drive plugged in.
1. Allow for the modification of files by typing:
2. Make a directory in Volumes to mount to. We will call it "usbstick" by typing:
Code:
mkdir /Volumes/usbstick
3. Before we plug it in we need to make reference to what other drives we see in /dev by typing (You might want to write them down):
4. Now plug in the usb thumb drive, wait a second then look for a new addition by typing:
5. Now lets mount it. Lets say you there are two new additions disk4 & disk4s1. Type the following (replace
msdos with
hfs depending on how the usb thumb drive is formatted. If you use it on a PC too then its msdos):
Code:
mount -t msdos /dev/disk4s1 /Volumes/usbstick
Then you can access your usb thumb drive at /Volumes/usbstick
If you are getting a basic understanding of the commands that Milanca posted then you should be able to supliment them with your USB thumb drive's location.
