Troubleshooting Without Diagnostics
Disk transaction problem. Either the directory

In Windows XP, right-click Start, 
click Explore, and select a drive.

The system may not 
have automatically 
recognized a newly 
installed device.
1. Run Computer Setup.
2. If the system still does not 
recognize the new device, 
check to see if the device is 
listed within Computer Setup. If 
it is listed, the probable cause is 
a driver problem. If it is not 
listed, the probable cause is a 
hardware problem.
3. If this is a newly installed drive, 
enter Setup and try adding a 
POST delay under Advanced 
> Power-On.
Drive jumper settings 
may be incorrect.
If the drive is a secondary drive that 
has just been installed on the same 
cable as the primary drive, verify 
that the jumpers for both drives are 
set correctly.

controller is disabled in 
Computer Setup.
Run Computer Setup and enable the 
Primary and Secondary IDE (ATA) 
controllers in Storage > Storage 
Options.

immediately after 
power-up.
Run Computer Setup and increase 
the POST Delay in Advanced >
