Flush Disk Cache

[BlazeLondon]

is there a function to flush the disk cache on a removable drive ?

so a user can just unplug it after files are written?

Sysinternals sync?

Don't think there is a autoit function to do it, but I'm not an expert, so anyone is there?

not free to distribute if you read the eula

At least in Windows XP each usb device has additional field "optymalization for quick removal" or "optimatization for quick access" or something like that in Device Manager for that specific device. Check it out. Unless you meant something else.

You might try it in c, i think this will work

// crt_flushall.c
/* This program uses _flushall
 * to flush all open buffers.
 */

#include <stdio.h>

int main( void )
{
   int numflushed;

   numflushed = _flushall();
   printf( "There were %d streams flushed\n", numflushed );
}

And if you do not find a builtin solution. Grab a copy of Dev-C, Cut and past the code @gafrost provided in a new project and hit the compile button.

Well Mr Frost!

Thanks to the nice person who left the last comments i compiled it no probs. cheers

Its very very fast; not like the sysinternals one that takes a good 3 or 4 seconds

this one just instantly says "3 items flushed" and i dont see any disk activity.

Is this really flushing the disk cache; for all drives or just my hard drive?

Not sure what this code does

UnxUtils has a sync.exe that you might be able to package in your script. Check it's EULA.

Not shure how you have monitored the USB disk until now, but I supose you could monitor with Filemon from sysinternals and see if you get any activity after the flush call.
