Porblem when checking the Filesystems of my BT3 on usb

[RadioactiF]

Hi, at first, thanks to umattu for his tutorial "BT3 on USB with persistent changes, using Linux"
Of course I m trying to install BT3 on my 2 GB Flash Drive, I successfully Create the Partitions and write them on my flash drive, then I write the Filesystems but when I tried to Check them I had a problem with the /dev/sda1 partition, when I put :

fsck -y /dev/sda1

it output :

fsck 1.39 (29-may-2006)
fsck:fsck.vfat:not found
fsck:error 2 while excuting fsck.vfat for /dev/sda1

the second partition /dev/sda2 is correctly checked !
I m using BT3 from bootable CDROM as a OS, and I have a U3 smart SanDisk,
So, is there any explications ?
P.S: when I was writing the file system I dont use :

user@laptop:~$ mkfs -t vfat /dev/sda1

because there was (-bash) ^^'
so I just put

mkfs -t vfat /dev/sda1

and it also output

mkfs.vfat 2.11 (12 Mar 2005)

thanks a lot for reading my post

Did you remove the U3 smart sanDisk software using their removal software first? You could try using dosfsck instead on the first partition and see if that makes a difference. You might not even need to check the file system. Worse case you have to reformat and start again.

I m not sure, but I think yes, I did it with their software.

so I put :

dosfsck -y /dev/sda1

and it output :

dosfsck 2.11, 12 mars 2005, fat 32, LFN
/dev/sda1: o files, 1/263616 Clusters

for /dev/sda2 it output :

dosfsck 2.11, 12 mars 2005, fat 32, LFN
Logical sector size is zero

You might not even need to check the file system. Worse case you have to reformat and start again.

I reformated again and again but I had the same problem when I try to check the Filsystems
what can I do right now ? ^^'

I try it with another USB disk (sony vaio 4go) but I still have the same the problem.
and to change the permission of the files "syslinux" et "lilo" when I do it the files become "read only mode " so I cant save the file "syslinux.cfg" after that I make the changes
can someone explain this to me plzz ?
