Using Ubuntu Windows installer, I dual boot Ubuntu 11.10 with Windows 7. I have an SD card for Readyboost which is seen and mounted when Ubuntu loads.
How can I stop the Linux OS from mounting the SD card?
The only way I know is to go into fstab and write a line with the auto mount set to noauto mount. You have to be signed in as Sudo to do so.
Here is an article that describes the auto mount and fstab process. I use fstab to auto mount drives on other pcs on our network so they should up as devices on my pc, this allows me to back them up as local.
hope this helps
I found the best solution here, which states:
I did this for the SD card and now it's not mounting.
