For a better chance of getting a good read:
- you could try and set the number of revolutions to sample to a higher value, e.g. for 5 samples -r5
- set the number of retries per track to a higher value, e.g. for 10 retries -t10

Changing the default values (especially -r as that is not conditional on the read being good or not) can significantly increase the time it takes to image a disk.

You can make the output much easier to read if you are looking for errors in an image by using -l8, restricting output to the format analyser results only.
As long as you are seeing OK for a track it's perfectly good. If you see OK* then the read is good, but there are things that might need your attention. Usually that means the track contains deviations from the expected format (that the image created can't fully represent, such as different ID values for sectors, changed track numbering and the like), however the data itself is error free.
The GUI version will give you a summary, but I am considering adding a simple summary to the console version as well at a later beta stage.

I'd also recommend creating stream files from bad disks, those could be used for data recovery at a later time - they are quite big though, so only recommended for bad disks (that have any value) and original duplicated disks, where they are mandatory for preservation.
