DOCUMENT:Q124558 28-JUL-2001 [win95x] TITLE :DriveSpace Err Msg: MINI.CAB File Is Missing or Damaged... PRODUCT :Microsoft Windows 95.x Retail Product PROD/VER:95 OPER/SYS: KEYWORDS:diskmem win95 kbDiskMemory ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows 95 ------------------------------------------------------------------------------- SYMPTOMS ======== You receive the following error messages when you run DriveSpace to perform an operation that requires full restartability: - Files required to manage your compressed drive(s) are missing on drive . To restore these files, copy the MINI.CAB file from your Windows 95 Setup Disk 1 or CD-ROM into your Windows directory. The next time you run DriveSpace, the missing files will be restored. ID Number: DRVSPACE575 -and- - Windows might not be able to restart this operation if it is interrupted. Check to make sure drive x is not full; you may need as much as 1.5 MB of free space to continue. ID Number: DRVSPACE311 CAUSE ===== These errors occur when the files in the hidden FAILSAFE.DRV\FAILSAFE directory on drive C (or the host for drive C) are missing and DriveSpace cannot find the MINI.CAB file in your Windows 95 SYSTEM subdirectory. These errors can also occur if there is a file named Failsafe.drv in the root folder of drive C (or the host for drive C). RESOLUTION ========== Copy the MINI.CAB file from your original Windows 95 distribution media to your Windows 95 SYSTEM subdirectory. NOTE: MINI.CAB is located on the standard 1.44-megabyte (MB) disk 1 of the 3.5-inch distribution media format (DMF) disk set and can be copied using Windows Explorer or at an MS-DOS prompt (using EXTRACT is not necessary). On CD-ROM installation media, MINI.CAB is located in the WIN95 directory. MORE INFORMATION ================ DriveSpace operations that can prevent Windows from restarting properly if interrupted by a power loss or accidental reboot are fully restartable. To ensure restartability in these cases, DriveSpace uses a mini-version of Windows (a subset of Windows 3.1 also used by Setup). DriveSpace extracts the mini-version files (from the MINI.CAB file in your Windows 95 SYSTEM subdirectory to a hidden FAILSAFE.DRV directory on the physical boot drive) before beginning an operation that requires full restartability. This ensures that DriveSpace can complete its operation in the event of a power loss or accidental reboot. DriveSpace requires the mini-version of Windows during the following operations: - Compressing an existing drive that contains Windows files (including the swap file). - Uncompressing a DriveSpace- or DoubleSpace-compressed drive that contains Windows files (including the swap file). - Changing the size of a DriveSpace- or DoubleSpace-compressed drive that contains Windows files (including the swap file). - Changing the estimated compression ratio (ECR) for a DriveSpace- or DoubleSpace-compressed drive that contains Windows files (including the swap file). You should not delete the FAILSAFE.DRV directory created by DriveSpace unless you have a MINI.CAB file in your Windows SYSTEM subdirectory. DriveSpace does not delete FAILSAFE.DRV after successfully completing a restartable operation. This allows future restartable operations to be completed more quickly.
