Any ideas whats wrong with it?
I've seen very similar messages when a HDD had bad blocks on it. Not that it's necessarily the case with your drive. However, it does suggest a hardware problem on the disk front.
Mark Rogers' suggestion that the cable may have got nudged during the RAM installation is a plausible possibility.
Another might be that there's a problem with one of the new RAM chips. If there's a data error on one of the "bits" then signals between hardware can get corrupted. I've also known this to lead to bad data getting written to disk when buffers are flushed (the most amusing case in my experience was when I noticed that filenames from 'ls' were coming out with some false characters; a bit of detective worked showed that these corresponded to one bit in the ASCII code being stick on "0" -- e.g.
"c" = ASCII 99 = 01100011 -> 01100001 = ASCII 97 = "a"
So took out the disk drive, looked at circuit board with magnifying glass, detected the smallest piece of fluff I've ever seen across two pins, went "puff" at at, and cured the problem; has to rename a few files after that ... ).
I think the suggestion to re-instate your previous setup and check everything out is very wise. Make sure all cables are well seated. Do this first, then if you still have problems report the details back to us.
Good luck, Ted.
