When navigating the file system of my USB drive in the terminal, some weird things happen that didn't used to happen on my Raspberry Pi B+. I'm not quite sure how to articulate this, so I'll just show what is

1. I open the command line and navigate to my USB drive with `cd /media/pi/MYUSB/`
2. I use `cd` to enter a folder of the USB drive with `cd /myFolder/myOtherFolder`
3. I navigate backwards to `myFolder` with `cd ..`
4. I try to navigate again to `myOtherFolder` with `cd /myOtherFolder`. However, this raises the bash error `bash: cd: /myOtherFolder: no such file or directory`

I have no idea what or why this is happening, but I used to be able to do this without the error message. Sometimes I have power outages that cause the Raspberry Pi to shut off with the USB drive in it, so I have "ghost USB drives" like the ones described in *[Ghost USB drives left behind when power is cycled off and on](https://raspberrypi.stackexchange.com/questions/73234/ghost-usb-drives-left-behind-when-power-is-cycled-off-and-on)*.
