Optimist. It just means the part of the binary you run are not random.
Randomness of *all* code paths would have to be checked, which you
probably can't do manually, so binaries are not a good check at all.
Since you didn't change any drives, chances are good that you really
lost very little data.

That's a good test, so you are lucky.

Is this on the same controller as the other broken disks were? Then this
should be it (or it's cabling, or the backplane, etc.). And you should
immediately shut down the RAID on that controller, as you might loose
data (or the whole RAID) when the controller writes random data. A
broken hardware is the worst thing to have. Replace it, test the new
parts *thouroughly*, and only then start to use the RAID again.
