ftdisk error is related to errors on the drive which should be rectified by running chkdsk drive letter /r

ftdisk is related to dynamic disks (ft stands for fault tolerance). This driver runs whenever dynamic disks have been configured.

The error is serious enough to trigger a blue screen. It can be easily fixed by restarting the CPU in Safe Mode, or by replacing the hdd cable. If opened, it could cause serious damage to the computer.
Mike Caulk

Just press F8 to going to boot menu at start, choose last working configuration, it will work. Before this Earlier, mine even can't be repaired using windows boot cd.

Dr.Web liveCD found ftdisk infrected with backdoor.tdss.2459, renamed ftdisk, now windows XP cannot load. [session3_initialization_failed]

ftdisk can be infectted with a virus
TR

it's loaded at boot time and it handles the IO to basic disks. Contrary to what another poster noted, I think ftdisk.sys is for basic disks whereas dynamic disks do not use ftdisk.sys directly. Instead dynamic disks are part of LDM which is a more full-featured LVM layer (really a version of Veritas VM). If you get errors from ftdisk.sys check your disk for IO errors, etc. and/or registry "disk key".

FTDisk (Fault Tolerant Disk) is a driver which helps NTFS correcting errors or remapping sectors (data is lost) that arise from bad disk sectors or clusters. It is always started before NTFS file system driver (that mounts NTFS partition or volume) and after Disk Device driver (that controls disk device activities), thus preventing NTFS from mounting bad disk sectors or clusters. It helps NTFS with SCSI or non-SCSI disks or other type of disks, but not in all cases because there are cases when this driver simply cannot recover error. It is a layer between disk and file system.
