TITLE: Presario Desktops Proactive Fix for Windows XP Unmountable Boot Volume Error VERSION: 1.0 Rev A DESCRIPTION: On systems that use the NTFS file system on IDE drives with caching enabled, the following error message may appear during startup: "Stop 0x000000ED " OR "Unmountable_Boot_Volume" This Softpaq provides a proactive correction, and will prevent the error from occurring. It will not resolve the issue on a system that already has the Unmountable Boot Volume error. The unmountable boot volume error is usually the result of an abnormal shutdown that prevents the hard drive from dumping the IDE CACHE. The NTFS transaction log file is out of sync with what was actually written to the drive, which is why the error occurs. The normal recovery process, when the error has already occurred, is to run chkdsk /f command from recovery console and then to continue. But in some Presario models the recovery console is not accessible and the customer will have to call service to get the SoftPaq SP20077 CD to access the recovery console and run chkdsk. If the customer already has SP20618 installed, an improper shutdown (and restart) will automatically start chkdsk and the customer will never see the unmountable boot volume error. This is a proactive fix for the scenario when the unmountable boot volume error has a chance of occurring on one of the Presario models listed below running Windows XP.
