Troubleshooting Without Diagnostics
Hard Drive
Problem Possible Solution
Hard drive error occurs. Hard disk has bad sectors or has failed. Use a utility to
locate and block usage of bad sectors. If necessary,
reformat the hard disk.
Disk transaction problem. Either the directory structure is bad or there is a problem
with a file. In Windows 98, 2000, or Me run ScanDisk.
Click Start > Programs > Accessories > System Tools >
ScanDisk.
In Windows NT, right–click Start, click Explore, and select a
drive. Select File > Properties > Tools. Under Error-checking,
click Check Now.
Drive not found (identified). 1. Cable could be loose. Check cable connections.
2. The system may not have automatically recognized a
newly installed device. See reconfiguration directions in
the “Hardware Installation Problems” section. If 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. Check drive jumper settings. If the drive is a secondary
drive that has just been installed on the same controller
as the primary drive, verify that the jumpers for both
drives are set correctly.
4. Check SCSI IDs to ensure none are duplicated.
Nonsystem disk message. 1. The system is trying to start from a diskette that is not
bootable. Remove the diskette from the diskette drive.
2. The system is trying to start from the hard drive but the
hard drive may have been damaged. Insert a bootable
diskette into the diskette drive and restart the computer.
3. Diskette boot has been disabled in Computer Setup. Run
Computer Setup and enable diskette boot.
