[SOLVED]When it boots from Hard drive can it see the flash?

I wanted to see if my user old data was still on the internal flash drive for websharepro I used fdisk -l but I guess it disabled the internal flash drive when it boots from a real hard drive. Is this right, or is there a way to mount it to look at it's data when you boot from a hard drive?

Wow looks like you can. From another post on this forum from pmcallihan He said how to copy wireless drivers from it.

So you can mount the Internal flash drive like this:

Code:

cd /
mkdir internal_flash_drive
ubiattach /dev/ubi_ctrl -m 3
mount -t ubifs ubi0:rootfs /internal-flash-drive

That makes a folder named "internal_flash_drive".

If you want to unmount it just do:

Code:

cd /
umount internal_flash_drive
ubidetach /dev/ubi_ctrl -m 3

Then delete the internal_flash_drive folder.

Code:

rmdir internal_flash_drive

That command will not let you delete it unless it's empty. It should be if you just used it to mount the internal flash drive.

This command shows the info of it. Looks like it has four 128 KB partitions. 4 x 128 = 512 what it has. Because look at this list of the flash drive partitions:
