FAT32 Live USB Question

[kbrafford]

I have a ginormous 32GB "Patriot" USB keychain drive, and I have done the following to it:

1) Formatted it FAT32 in Windows
2) Used the Universal-USB-Installer-1.7.9.1 to create a persistent Live USB (with 4GB Persistence casper-rw file), without reformatting, so it's still FAT32

That works really well, and I have a flash drive with 22GB of free space on it.

Next,

3) I created a directory off of the root called zDATA ("z" so it shows up at the bottom)

That is how I add/remove data to/from the drive from Windows

Question:

How can I mount the stick in Ubuntu so I can also access the zDATA directory?

Thanks for your help!

Any data that you put to it from windows can be found in "cdrom" when you are booting from the USB drive.

ie look in cdrom/zDATA

Looks like it's capital Z:

ubuntu@ubuntu:~$ ls /cdrom
ls: cannot access /cdrom/ZDATA: Input/output error
autorun.inf install pool ubuntu ZDATA
casper ldlinux.sys preseed Uni-USB-Installer-Copying.txt
casper-rw md5sum.txt README.diskdefines Uni-USB-Installer-Readme.txt
dists pics syslinux wubi.exe
ubuntu@ubuntu:~$ ls /cdrom/ZDATA
ls: cannot access /cdrom/ZDATA: Input/output error
ubuntu@ubuntu:~$

But still is not usable by me.

Is there no way to make this drive accessible by me?

If you put stuff in /cdrom while booting the pendrive can you access it from windows?

Open the thumb drive in nautilus do you see ZDATA?

No, nothing I do lets me see /cdrom/*

And I *can't* open the thumb drive in nautilus. It doesn't show up as its own thing at all.

How about, start nautilus, click filesystem, then click cdrom.

pl give the output of fdisk -l

Ah, that works. I can see my ZDATA directory and read its files, but I can't write to it. Is there any way to change that?

Try creating a directory named maybe XDATA in the cdrom directory while booted from the flash drive.
It may not want to modify a folder created with Windows for some reason.
