A. When you run Check Disk (CHKDSK) or AutoChk on a partition on which NT is installed you may receive one of the following messages
- Cannot lock volume for direct access
- Cannot open volume for direct access
This can be caused by a 3rd party application locking the partition such as a virus checker or disk monitor tool. To correct disable any 3rd party services or devices that may be locking the partition.
- Start the Services control panel applet (Start - Settings - Control Panel - Services)
- Select the service and click Startup
- Set the startup type to Manual and click OK
- Repeat for any other services
- Start the Devices control panel applet (Start - Settings - Control Panel - Devices)
- Set the startup type to disabled for any 3rd-party devices who you think might be causing the lock problem but BE CAREFUL. If you are unsure the device you are disabling may stop system startup create a second hardware profile and test (see 'Q. How can I safely disable a device?').
- Restart the machine, the drive should no longer be locked
