Problems with writing to msdos format flash drive.
I am running Ubuntu 12.04
I have a flash drive in msdos format. I am having problems writing files to subfolder.
I can read files.
I can create folders.
I can write files to the root directory.
The data initially appears to be OK. After ejecting the drive and remounting it the folder is empty.
What is going on. What can I do to fix this.
