Checking the Installed Devices List
The HDD-1 or FDD-1 represents the first drive in the
system configuration, respectively. Similarly, the HDD-2 or
FDD-2 represents the second drive, usually attached
through a Dock I.
Notes:
1. Neither the Dock I nor the adapters and SCSI devices
installed in the Dock I appear as icons on the screen.
2. HDD-1 and HDD-2 icons are for the 2.5-inch
ThinkPad hard disk drive.
If the devices are installed, but the icon appears in a gray
shade rather than a dark shade on the basic diagnostic
screen, it means that the devices are defective. Power-off
the computer and make sure that the devices are correctly
connected. If the symptom still remains after the computer
is powered-on, replace the devices or the main board of
the Dock I.
