Originally my system had two SATA disk drives - I added an extra SATA disk drive to my system and when accessing this disk it sometimes take about 50 times longer to access the drive. (Windows Explorer can take about 2 mins to populate the basic directory and there is nothing special about the directory)
This doesn't happen all the time, but can't identify a pattern at the moment.
Any ideas what I've done wrong?
(Using Windows Vista Home Premium - PC is custom made - this is just on my development PC. What other useful info can I give?)
