Hello. I was wondering if in Win XP or Vista, is there a way to disk defragment multiple devices?I go into disk defrag at this time and can only do one drive at a time. I run more than one internal drive (and have some external drives). So I need somewhat of an automated process to turn on and leave alone. I am using this option in Norton 360, it works fine as far as I can tell. But I would assume a windows application is more accurate, or thorough. Dual boot: Xp Home Edition 32-bit/Vista Home Premium 32-bit, Laptop: Vista Home Premium 64-bit.Thank you.

Providing that the drives do not host the operating system or the pagefile you can do this with a simple batch file:-------------------chkDatVol.bat------------------chkdsk x: /f /xchkdsk y: /f /xchkdsk z: /f /x-----------------------------------------------------Do Chkdsk /? at the Command Prompt for more help.

Hi,The version of Disk Defragmenter MMC that is included with Windows XP has the following limitations:a. It can defragment only local volumes.b. It can defragment only one volume at a time.c. It cannot defragment one volume while it is scanning another.d. It cannot be scheduled. If you need to schedule disk defragmentation, use the Defrag.exe command line tool.For additional information about using the command line Defrag.exe tool, click the following article number to view the article in the Microsoft Knowledge Base:Description of the New Command Line Defrag.exe Included with Windows XP http://support.microsoft.com/kb/283080/EN-US For addiitonal information refer to the article below:How to Defragment Your Disk Drive Volumes in Windows XPhttp://support.microsoft.com/kb/314848 Hope this information was helpful.Thanks and Regards:Shekhar S - Microsoft Support.

Yeah, I must have been still half asleep when I replied...He can do it in a batch file with the defrag command.John
