HowTo write column data in gtkDialog TableBox? [Solved]

The data for the gtkTableBox looks like this:

Code:

sda1|M|
sda3|M|
sda5||
sda6|M|
sdb1||
sdb5||
sr0||
sr1||

The sed command I`ve used before doesn`t want to do the job, ${1} is the drive (sda3):

Code:

echo "$(</tmp/drvinfo)" |sed "s/$${1}||$.*/\1{B}/" > /tmp/drvinfo

I`m trying to get it to put a "B" on the end, like this: " sda3||B " and remove it: " sda3|| "
I also need to write and remove the middle position, like this: " sda3|M| " and "sda3||"

So for a given row (record) I need to write a given column (field) independantly.
I could do this in several lines of code, but I`m sure sed will probably do it in one line...

I didn`t find how to make sed do it in one line, but I got close...

Code:

ROW=`echo "$(<$drvINFO)" |grep $1`
COL=`echo "$ROW" |cut -d '|' -f 3`
if [ -z "$COL" ];then                                                                                              # set drive to boot mount
   NEW="$ROW"B
   echo "$(<$drvINFO)" |sed "s/$ROW/$NEW/" > $drvINFO
   echo $1 >> $drvBOOT
else                                                                                                                         # set drive to not boot mount
   NEW=`echo $ROW |sed 's/B//'`
   echo "$(<$drvINFO)" |sed "s/$ROW/$NEW/" > $drvINFO
   echo "$(<$drvBOOT)" |grep -v $1 > $drvBOOT
fi

This toggles the column data for the input file for a gtkDialog TableBox.
The TableBox reads the file $drvINFO, variables $ROW, $COL, and $NEW are obvious.
