New Encrypted partition on usb pendrive??

doomguy84 · 2021-12-10 11:16:53

Hello!
I am in this condition, i made a bootable little pendrive, using syslinux, just to load some utilities like memtest, hdat, miniXP... the partition in a fat32
I also create a "efi" folder on the root of that partition to be able to run some utilities on uefi systems.

Now my question, if I make some space on that pendrive, can i make a new partition, maybe with btrfs, encrypted ??
So i will use that partition to store my personal files.

In this case, on Windows will be "hidden", on Linux when i wanna mount that partition it will ak me for a password, right?

Thanks!

I use as similar setup myself, though MBR-based. So the idea in general is right.

Windows XP and older will not see the partition, as they can’t properly handle partitions on removable media. Only the first one is accessible. Windows after XP will not recognize the partition and will consider it “broken”, likely⁽¹⁾ prompting you to “fix it” by formatting. On Linux you may mount it normally with a passphrase or a key.

Standard warnings apply: do not keep valuable files on an USB stick, unless they are backed up. In particular if you are at risk of accidently telling Windows to “fix the problem”.

What exactly do you want help with? Adjusting the existing partitions / file systems to make space for the new one? Creating the new partition / creating the new file system? Mounting the file system from the existing installation?
