SCP media test in Linux, verify question?

[Pitou]

Hello,

I just started working on a media test for Linux re-using the source code from Keir Fraser.

I did a lot and so far it's working pretty well. For now, I'm writing a 4us flux for a total of 200ms.

I'm now reading back the data, but not sure how to do the compare. As we know the values are not always exact from read to read.

What is the margin error we can assume?

Also, the first 2-3 bitcells are often very far from original value. Is that normal?

How should I do the compare and assume that a track is ok?

Thank you.

Pitou!
