You receive a "Disk in drive <X> is not formatted" error message when you try to access an SD or MMC drive (823084)

SYMPTOMS

On a Windows 2000-based computer with a Secure Digital (SD) card or a MultiMedia Card (MMC) in the card reader, you may receive the following error message when you try to access the SD card or the MMC drive:

Disk in drive X is not formatted

You receive this error message after you put the computer in standby and you switch the SD card or the MMC in the reader with another card. When you resume the computer and you try to access the SD card or the MMC drive, you receive the error message. The problem occurs only if you try to access the drive within 15 to 20 seconds after you log on. This problem does not occur if you replace a Compact Flash (CF) card while the computer is in standby.

Additionally, the following error message may be logged in the Application event log:Event Type: Error
Event Source: Removable Storage
Event Category: None
Event ID: 17
Description: RSM cannot manage library Disk Name. It encountered an unspecified error. This can be caused by a number of problems including, but not limited to, database corruption, failure communicating with the library, or insufficient system resources.

CAUSE

This issue is caused by a code problem in the Disk.sys disk driver. Windows 2000 includes an optimization for handling IOCTL_DISK_GET_PARTITION_INFO operations in the Disk.sys driver. This optimization does not re-enumerate a device every time that the partition information is requested. This method works well for non-removable hard disks, but does not work as well for removable disks that can be replaced with different media while the computer is in standby or hibernate. If a removable medium is replaced while the computer is in standby or hibernate, no media change notification is received by Windows. This causes Windows to read from the same boot sector number on the new disk as was used on the previous disk.
