I can't access the E drive partition on Hard drive 1 part 0. The beta did access this. I have 2 IDE hard drives. Drive 0 is accessed without any problems. System info lists both drives and all partitions. My computer shows drive c, d this is on drive 0 but drive E is now listed as the dvdrw drive.

What file system is the E partition?Try going into disk management and see if the E partition shows up there.Right click on the 'Computer' icon and choose 'manage'... In the window that opens, on the lower left you will see 'Disk Management'.
