I recently replaced a HD on a PM 5200 when it stoped showing up and both norton and Techtool couldn't find anything. I put in the new HD, installed the system and everything worked fine, for about a day. Now the new HD won't show up unless you boot from a cd, and even then won't write data it gives me an error that there is -2995738 blocks available. Please help!!
p.s. it made a high pitched sound from the left speaker at startup once.
