SYMPTOMS

Windows cannot defragment this drive. Make sure the disk is formatted and free of errors. Then try defragmenting the drive again.
ID No: DEFRAG0026

CAUSE

This can be caused by running an earlier version of Defrag.exe than the version included with Windows 95 OEM Service Release 2 (OSR2).

In Windows 98, this behavior occurs when a shortcut to the earlier version of the Disk Defragmenter tool is put on the desktop.

RESOLUTION

To resolve this problem, extract a new copy of the Defrag.exe file from your original OSR2 CD-ROM or disks. To do so, follow these steps:
1.Open an MS-DOS prompt in Windows 95.
2.Change to the Windows folder, and then type the following line:

ren defrag.exe defrag.xxx
3.Insert the OSR2 CD-ROM or disk 6 in the appropriate drive.
4.If you are using the CD-ROM, type the following line

extract <x>:\win95\win95_05.cab defrag.exe /l <z>:\windows

where <x> is the CD-ROM drive letter and <z> is the drive containing the Windows folder.

If you are using disk 6, type the following line

extract <x>:\win95_06.cab defrag.exe /l <z>:\windows

where <x> is the drive containing disk 6 and <z> is the drive containing the Windows folder.
