TP 770ED - Scandisk failure with 8 GB hard drive
Applicable to: World-Wide
Symptom:
An error message can occur when running ScanDisk on drive D: in MS-DOS mode. This could be run manually with the command SCANDISK D: entered at the DOS command prompt, or you could be prompted to run Scandisk during system start-up if Windows was not properly shut down the last time the system was used.
This is the message that would appear:
"ScanDisk cannot read from the last cluster on drive D. This cluster is either damaged, or your system is not configured properly. Drive D may need to have Logical Block Addressing (LBA) enabled to work properly, or its disk partition may be incorrectly marked as a non-LBA partition. Data Loss can occur if your LBA setting or disk partition type for this drive is misconfigured.
Check your computer's BIOS setup utility, or contact your computer manufacturer, or have your computer checked by a qualified computer hardware technician.
If you are sure your drive is configured correctly, click Continue to have ScanDisk check drive D for errors."
If FDISK (Windows 95 version) is used to look at partition information, the following is found:
On failing system |
On good system | |
Partition C: 1 |
2045 |
2045 |
Partition 2 |
5759 |
5759 |
In "Display the Logical Drive Information"
D: 5766 FAT32 <----- on failing system
D: 5759 FAT32 <----- on good system
Configuration:
770ED with 8GB hard drive and preloaded Windows 95 operating system.
Solution:
The Extended partition that contains the logical D: drive must be deleted and then recreated using the FDISK (which is in Windows 95). This will not harm any data contained on the C: drive but you MUST save any data on the D: drive to another drive, diskettes, or other back up device, because all data on D: will be deleted by this process. The D: drive does not contain data when shipped from the factory.
Steps to fix this problem:
Additional information:
This situation has been corrected on systems built after June 1998.
