When a secondary hard drive is purchased, a new bezel is installed on the chassis which provides space inside the chassis for the secondary hard drive (Figure 1). The floppy bay is no longer available with this bezel.
In the event that the secondary hard drive must be replaced, the replacement drive must be a Western Digital or Samsung because of thermal constraints in the chassis. The BIOS automatically performs a check at POST, and the check stops at an F1/F2 prompt if an invalid configuration is detected.
A message appears (Figure 1) that informs the user of the invalid configuration and allows them to choose to continue, knowing there could be a long-term reliability risk to the HDD or ask for a redispatch."
My situation is that I added the 2d HDD, so I don't have the correct bezel. Looks like I need to swap out the 2d HDD for a WD or Samsung, or go eSATA, or buy a different form factor.
