BT5R3 USB Persistent Install

Hello everyone,

one more topic about this :\
Well, 1st of all wanna say thank you for this great community.
And 2nd, yes, I already used search and tested various types of persistent usb install.

Methods testes and the fails I'm having:

1st - http://www.backtrack-linux.org/forum...ad.php?t=47479

This method posted by an user, seamed kite good and easy, the probably came when I wanted to select the usb pen, and it does not appear. ( It's connected to my vmware machine)

2nd try - http://www.backtrack-linux.org/wiki/...Persistent_USB

All went well till the phase:

mkfs.vfat -F 32 -n BT5 /dev/sdb1
mkfs.ext3 -b 4096 -L casper-rw /dev/sdb2

the 2nd command I can run it well, but the 1st one says me input/output error.

Going up ahead, the next comand says:

mkdir /mnt/sdb1
mount /dev/sdb1 /mnt/sdb1

Here, I had another problem. the 1st command worked good, but the 2nd one failed. Saying that I need to specify the format.

There is actually anyone who already installed BT5R3 persistent in USB?

For the ones that want it with full disk encryption (not my case) use this link:

Thanks in advance for the help guys.
Would like to solve this as soon as possible.
To start focusing in more deep things.
