| Event Information | According to Microsoft: This problem may occur if your Windows NT Server 4.0 computer uses disk mirroring. Disk mirroring is also known as redundant array of independent disks (RAID) level 1. The Windows fault-tolerant disk driver (Ftdisk.sys) disables a mirror set and fails synchronization of the mirrored disks if both of the following conditions occur: 1. Ftdisk.sys encounters an input/output (I/O) error on the boot partition of the master disk in the mirror set. 2. Ftdisk.sys receives a status back from the mirrored hard disk that experiences the I/O error that is different from the STATUS_DEVICE_DATA_ERROR (0xC000009C) status and the STATUS_CRC_ERROR (0xC000003F) status. |
