Microsoft Windows versions 3.0, 3.0a, 3.1, 3.11
Microsoft MS-DOS operating system versions 5.x, 6.0, 6.2, 6.21

SYMPTOMS

Ashton-Tate (Borland) has noted that running the dBASE IV version 4.11 CACHEDB.EXE disk cache with Windows SMARTDrive (SMARTDRIVE.SYS or SMARTDRV.EXE) causes dBASE and/or Windows to stop responding (hang).

If you use the MS-DOS 5.0, 6.0, or 6.2 versions of SMARTDrive with CACHEDB.EXE, the following error message is displayed:

A serious disk error occurred while writing to drive <x>.

where <x> is any hard disk drive letter.

WORKAROUND

To correct this problem, do not use both disk caches at the same time.

To turn dBASE IV's CACHEDB.EXE disk cache utility off, type the following command in the dBASE directory:

CACHEDB OFF

To turn the dBASE IV's disk cache ON, type one of the following commands in the dBASE directory:

CACHEDB EXT

(To use extended memory)

CACHEDB LIM

(To use expanded memory)

Microsoft recommends disabling the dBASE cache because it only helps dBASE, whereas SMARTDrive helps all applications.
