DOCUMENT:Q115378 25-NOV-1999 [msdos] TITLE :PC Tools 9.0 Cannot Recognize DriveSpace Format; Use ScanDisk PRODUCT :Microsoft Disk Operating System PROD/VER:MS-DOS:6.22 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft MS-DOS operating system version 6.22 ------------------------------------------------------------------------------- SUMMARY ======= PC Tools version 9.0 Optimizer generates the following error message when used with DriveSpace: Optimizer Execution Error The DBLSPACE drive internal structure is damaged. Optimizer cannot continue. Running PC Tools DiskFix as detailed the PC Tools "User's Guide" to correct this error results in corruption to the DriveSpace compressed volume file (CVF). PC Tools 9.0 does not recognize the new DriveSpace format; therefore, to avoid possible data corruption, run MS-DOS 6.22 ScanDisk rather than PC Tools 9.0.
