yes friend you are right
you can transfer modules from track to another free track and i think in your model 256 tracks
from track 1---132 are free nondata spare track you can choose any track from them by 2 method
1- read mod 01 dir then only open firmware map modules and choose your bad module then press number of track that y like
2- you can use aba choose your free aba and put your module on it this method very good with big module like e1 e2 and so on cause size of module big than size of track and impossible to add
on only 1 track aba transfer mode is better to you
but check another modules in read and write to check if you have read only problem or only bad sectors on your module
DFL-WD IS BETTER TO YOU IN THIS PROBLEM
coz its important to decide where y go
