Ubuntu v9.04 won't save Anything on USB Flash Drive

[corsairgt]

I've installed v9.04 on a 16 GB USB flash drive. However, it wouldn't save any configuration, updates or new software. Does anyone know why?

You might have set the flash to read-only (check whether you have a button with a lock/unlock symbol on the flash).

The filesystem might also be mounted read-only. Check what the "mount" command gives in a terminal.

My flash drive doesn't have a lock.

If the filesystem is mounted as read-only, how do I change it to read and write. I never had this problem when I was using v8.04.

Try running a check of the drive ie
First check to see what the media is assigned

sudo fdisk -l

(lowercase L)
if it is assigned /dev/sdb1, then try this command:

sudo dosfsck -a /dev/sdb1

then test flash again

What do I need to do next?

Hmmmm... kinda funny. What started your boot, seems to me you are running from a ramdisk (your / is mounted as rootfs). Seems things weren't really installed on your disk.

But I'm not quiet sure.

I would guess your flashdrive is identified as /dev/sda.

what happens if you execute the following:

mkdir /tmp/sda1
sudo mount /dev/sda1 /tmp/sda1
ls /tmp/sda1

Do you see a root filesystem (with bin, etc, usr, etc...)?
