Check out F3 at<br>> <http://oss.digirati.com.br/f3/>. The f3write and f3read programs will<br>> do a thorough check that will take hours to complete. If you build the<br>> experimental parts, you will also have an f3probe program that will do<br>> a much faster test based on the author's knowledge of how fake flash<br>> drives work. It will not only tell you the true size of the drive,<br>> but will also tell you a command to run (using the included f3fix<br>> program) to "fix" the drive, which doesn't actually fix it, but instead<br>> creates a single partition that ends at the last good sector. Since it<br>> tells you what that last good sector is, you can also repartition the<br>> drive however you want, as long as all partitions end before that sector.<br>> <br>> Chuck<br>> <br>> -- <br><br>Sounds perfect. I'll have a read on that today. Thanks, Dale.<br></div> </div></body>
