Hi.

I wanna change the buffer size of the drives on my computer.

For example I wanna increase it for a HDD or USB key, or to set it 0 for a ramdrive...

Is it possible? And if it is, how...?

Thank you for any help.

Best regards, John

If you're speaking about the write cache, you can enable it or disabled in the device manager using the properties of the drive and the policy tab.

See also this MS KB: http://support.microsoft.com/kb/811392 about managing the cache from command line.

Thank you

But I wanna know also how to change the size of the buffer, no just enabling/disabling it..

And could someone change the word "buufer" from the topic's title into "buffer"? I can't change anymore... Thank you.

Maybe change it form "buufer" to "cache" ,

The "buffer" is normally intended as "hardware", as in:

Yes, you're right

And thank you.

Later edit:

I tested the programs and I don't see how to set the cache min/max values for every drive.

NtCacheSetter sets min and max value but not for each drive.

Anyway I tried some values but I didn't see a change in what Task Manager reports.

SetSystemFileCacheSize is not for Windows XP.

FileCacheTest is for testing.

Yep

The message was: YOU CANNOT. (but there are some small tweaks that may mitigate the issues).
