Hummm now that i had not checked    out put is 

7-of-9:/ # blkid
/dev/sda1: UUID="49c2a61c-19e8-4f45-b8ef-72507d60ee06" TYPE="ext2" 
/dev/sda2: UUID="b25ccd70-a144-40af-8126-303d7333cdb4" TYPE="swap" 
/dev/sda3: UUID="a1439104-fcea-4c90-b0fb-2340154a9eae" TYPE="ext4" 
/dev/sda4: UUID="34fd95b0-a146-47a8-8fa4-78dcedd8c127" TYPE="ext4" 

in this case thou they agree  , my problem is mainly with /home  .

Thanks   
Pete .
