C HKDSK FREUENCY

[Mac]

Not normal. 0% is normal, unless you have manually scheduled a CHKDSK.

On my Vista computer on restart and or reboot, CHKDSK goes on 50% of the
time.
What is the normal ratio, if any ?
Is excess frequency a sign of trouble ?

It should not run on startup unless the drive is flagged as dirty, and
that's not normal. I have not had it run once on this installation since it
was first installed last November.

To check whether the dirty bit is set, from inside Vista open an elevated
command prompt. Go to Start, type in cmd, right click on it at the top
left, choose Run as Administrator. Then give the command:
chkntfs c: (subsitite for C: whatever the letter for whatever volume you
want to check).

If it's clean it will come back with a reply, "C: is not dirty".

I suggest you download a drive diagnostic utility from the hard drive
manufacturer's web site. That will create a bootable floppy or CD. Boot
from that to check the health of the drive. If that checks out, then look
for other causes.

It shouldn't run on start unless you have set it up to run and usually
that's once although you could set it up every time.

This is an explanation of how chkntfs works:

I would run a chkdsk /R when you run it (it can be lower case).

Q. How can I stop chkdsk at boot time from checking volume x?

A. When NT boots it performs a check on all volumes to see if the dirty bit
is set, and if it is a full chkdsk /f is run. To stop NT performing this
dirty bit check you can exclude certain drives. The reason you may want to
do this is for some type of removable drive, e.g. Iomega drives:

Run the Registry Editor (Regedt32.exe). You must use Regedt32.exe and not
Regedit.exe
Goto HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager
Change the BootExecute value from:
autocheck autochk *
to:
autocheck autochk /k:x *
Where x is the drive letter, e.g. if you wanted to stop the check on drive
f: you would type autocheck autochk /k:f *. To stop the check on multiple
volumes just enter the drive names one after another, e.g. to stop the check
on e: and g: autocheck autochk /k:eg *, you do not retype the /k each time.

If you are using NT 4.0 with Service Pack 2 or above, you can also use the
CHKNTFS.EXE command which is also used to exclude drives from the check and
updates the registry for you. The usage to disable a drive is

chkntfs /x <drive letter>:
e.g. chkntfs /x f: would exclude the check of drive f:

To set the system back to checking all drives just type

chkntfs /d
