Most disk problems are not "bit rot" but sleeve problems. In many cases, 
too many disks are squashed together causing the sleeve edges to 
compress. This creates excessive friction within the sleeve. In some 
cases, the disk won't even turn.

This problem can usually be solved by breaking the plastic spot welds 
around the edges of the sleeve and bending out the plastic so that the 
sleeve is loosened. The disk will spin at the correct speed and usually 
is back to normal.

As for Sands of Egypt, check out the data on my site
