Just bumping this thread up to get it noticed again. I too am having the same problem and have been ever since I upgraded to 6.12 from 6.03. I am using WinXP if that makes a difference. I ran the varies write testing scripts that people posted and get the same numbers (or very close depending on other writes that occur too).

Code:
It Stoped Working After 32767 Tries.  


Here are links to three other threads reporting this same bug. PLEASE fix this!
