John,
>>… writes to the disk automatically, the cache being a buffer. This is the
default for SMARTDRV for DOS ver 5.0. With DOS 6 this can be enabled with the
/F switch…
With the old Smartdrive, the only write option is on or off, and the manual
states "…writes information from memory to disk at times when other disk
activity has slowed." And it cautions "Check that smartdrive has completed all
write caching before turning your computer off… (with /C)". The new switch
/F "writes cached data after each command completes" not "when other disk
activity has slowed", so my whole point here is that the OLD smartdrive did
delay the writes to some point, and did not write to disk after each command
automatically, like the new one has the ability to do. I really haven't payed
much attention to the new write options since I run it as simple as can be,
smartdrv /x, read – yes, write – no, period. I just don't trust write caching
at all.
