You are having a problem with your drive, or a utility reports that the partition is somehow invalid, and it may be caused by incorrect ending cylinder information on the drive. This document explains the procedure for diagnosing the problem.
Before you begin: If you have an older PowerQuest product, the path to PARTINFO will be different than those mentioned here. If you are having trouble finding the PARTINFO executable, you can also download it from the Symantec FTP site.
Be sure to download the appropriate version for the operating system you are running:
Partinfo.zip for DOS
PartIn9x.zip for Windows 95, 98, or Me
PartInNT.zip for Windows NT, 2000, or XP
Once you download the file, you must unzip it using an archive utility (such as WinZip).
The procedure for running PartitionInfo to diagnose an ending cylinder problem depends upon you operating system. Follow the instructions below that are applicable to your operating system.
To diagnose the problem from Windows® 9x, NT, 2000, or XP
- Follow the instructions for your product:
- Norton PartitionMagic 8.0: Click Start > Programs > Norton PartitionMagic 8.0 > Norton PartitionMagic 8.0 Tools > PartitionInfo
- PartitionMagic 8.0: Click Start > Programs > PowerQuest PartitionMagic 8.0 > PartitionMagic 8.0 Tools > PartitionInfo
- VolumeManager 2.0: Click Start > Programs > PowerQuest VolumeManager > PartitionInfo.
- Drive Image 2002: Open the main Drive Image folder (default location is \Program Files\PowerQuest\Drive Image 2002), and double-click the appropriate version of PARTINFO for your operating system. (Partin9x.exe for Windows 9x, PartinNT.exe for Windows NT, 2000, or XP.)
- Drive Image 7.0: Open the Drive Image Utility folder (default location id \Program Files\Powerquest\Drive Image 7.0\Utility). Double-click the PartinNT.exe file.
- On the Physical Drive drop-down list, click Disk 1.
- In the Disk Geometry Information section, click the last row to highlight it.
In the Disk & partition errors pane, you should see something similar to the following:
Info: Begin C,H,S values were large drive placeholders.
Info: End C,H,S values were large drive placeholders.
Actual values are:
57673350 0 00 3590 1 1 07 4864 254 63 57673413 20482812
- Compare the 8th number under "Actual values" with the number of cylinders listed in the Disk Geometry Information section, as shown in the following image:
The number of cylinders listed in the Drive Geometry Information section should be one greater than the value in the Disk & partition errors pane. In the example, the total number of cylinders is 4865, and the ending cylinder of the last partition is 4864, which is correct. If the ending cylinder number is equal to or greater than the total number of cylinders, the partition is invalid.
Running PARTINFO from DOS or Windows 3.x
- Restart the computer to a DOS prompt (not a Windows command prompt).
- Change to the directory that contains Partinfo.exe.
For example, if you want to run PartitionInfo from the PartitionMagic rescue disks, insert the first rescue disk and change to the A drive.
- Do one of the following:
- To print the PartitionInfo report, type: PARTINFO > LPT1 and then press Enter.
- To save the output as a text file named Partinfo.txt on the floppy disk, type: PARTINFO > A:\PARTINFO.TXT and then press Enter.
Note: For information about command line switches, you can use with PARTINFO, see PARTINFO switches.
