Running chkdsk every time you boot NT is normally not neccesary, is it? It 
only makes the boot up time about 5 minutes longer? :)

Or, run the Disk Administrator, It can all be done from within there.

Well... may be we are not speaking about the same thing then?
First of all, I just ran a little check here on my BBS computer (NT 4.0 
Server SP3). It has been running for about 4 months continously now, without 
a reboot, and chkdsk did not find any errors at all! When I ran the same 
computer (with the SAME HD under DOS 6.22/DV2.73/QEMM8.0), I had lost cluster 
problems every other day! So it's my experiance that NTFS is much more 
reliable and stable in this area than any of the FAT systems.
I also looked up the Course Compendium from Microsoft: Microsoft Education 
and Certification; Supporting Microsoft Windows NT 4.0 Core Technologies, 
Student Workbook, and the section about the NTFS filesystem states in Module 
5, pages 152 and 153 the following:
---quote---
NTFS additional features:
....
Transaction-based recoverability. NTFS has high reliability. It has a 
recoverable file system that uses transaction logging to log all folder and 
file updates automatically. This is used by Windows NT to redo or undo 
operations that failed due to system failure, power loss, and so on.
Bad-cluster mapping. NTFS supports the recovery technique of bad-cluster 
remapping. If an error occurs because of a corrupt sector on tha hard disk, 
NTFS allocates a new cluster to replace the cluster with the corrupt sector. 
NTFS marks the original sector as corrupt. This is transperent to any 
applications performing disk I/O.
....
NTFS Implementation Considderations:
Recoverability is designed into NTFS. Users do not have to run a disk repair 
utility on an NTFS partition.
....

This is what I meant when I stated that NTFS is "self fixing". Am I wrong 
here? Or are we talking different things?
