Microsoft has released a hotfix for fixing a very serious issue in Windows 7 or Windows Server 2008 R2 that is affecting users whose computers are attached with hard drives larger than 2 terabytes of disk space. The consequences of this bug is very fatal and may cause volume corruption and if the corrupted volumes include the system partition, than users cannot start the computer.

This issue occurs because of the crash dump disk driver (Diskdump.sys) cannot address more than 2 terabytes of disk space. The Diskdump.sys driver can address up to 2 to the power of 32 sectors. If the sector size is 512 bytes, the driver can address up to 2 terabytes of disk space. If the actual offset is larger than this limitation, the driver incorrectly truncates the offset and saves data to a wrong location. Therefore, one or more volumes on the disk are corrupted.
