The format command in fx is a so-called low-level format. The term is misleading because there isn't any "high level format": when you normally prepare a fixed disk, you do so by installing a disklabel, partitioning (these first two steps are part of fx), and creating filesystems (which is done using mkfs).

To check if the disk seems healthy after the format operation, you could use the following command:

Code:

fx> /bad/showbb -g

to display the GLIST. These are all the defects in the grown defect list (those that manifested since the drive was made). The fewer there are, the better. If this is fewer than 50 or so the drive is fine. Over 100 and it is probably worn out.

Ok i can try to do this for the first thing. I ask to you, because i have understood some thing but not everithing, if the disk result fine, what are the step that i follow when i use FX menu. 
The first is to select "reformat", but for example, i can choose A to make auto reformat? Then i need to make "Label" but for one or all partitions?...etc..
Unfortunately, not knowing the irix/unix environment, I have all these specific questions that I can't give a good answer to. For this I need a step-by-step procedure...

For example also the mkfs command, i know that is used to format partitions, ok but where can i find it? under Fx command? under console? and how can i invoke console?
And what is the command line to use? ...all questions that i have difficulty to know
