I started getting a ton of code 50 errors with Eboostr and hidden memory enabled. I was also using a cache on an Acard RAM drive. I don't know if it's Eboostr or not. Norton Ghost 14 also acting (more) strangely than usual.
Going to try the following and see if the issue returns: Using 1GB regular RAM and 2GB on a different, mechanical hard drive. If that's ok I will then try enabling hidden memory, increasing the RAM cache as well. If that is ok, I am going to take the mechanical HD out of the equation and put the Acard RAM drive back in.
Again, just not sure right now what is causing this, if anything, and even if it is Eboostr's fault. I don't trust Norton Ghost any further than I can throw it, but Acronis tends to give me networking issues so I don't use it.
