- TITLE:
- STACKER and disk-cache programs.
-
- OVERVIEW:
- While STACKER includes its own cache, the driver is compatible with other
- products that perform the same function.
-
- Norton's NCACHE and Microsoft WINDOWS' SMARTDRV.SYS are loaded from the
- CONFIG.SYS, usually before STACKER. Other programs, such as PC-KWIK and
- PC-CACHE, load from the AUTOEXEC.BAT file, after STACKER.
-
- ISSUES/COMMENTS:
- 1) Some cache programs (e.g., PC-CACHE, PC-KWIK) may report that a
- particular drive letter is not eligible for caching, but caching proceeds
- normally.
-
- 2) When multiple cache programs are operating, disk reads/writes may have
- unpredictable results. Use of memory may also be negatively impacted.
-
-
- RECOMMENDED ACTIONS:
- 1) Alter the settings for the cache so that the uncompressed, host drive
- is cached. This will, by extension, cache any STACKER volumes residing
- on it. (The PC-KWIK message can be avoided by excluding the STACKER
- volume when the cache program is invoked. Consult PC-KWIK documentation
- for the appropriate parameter.)
-
- 2) If a commercial cache program is running, specify a STACKER cache of 0
- bytes (/M=0)
