Hi, My computer is running the concistency check. It's at stage 3 and
when it's almost complete it's starts to "replace invalid security Id
with default security id for file ******" it's been doing this for a
while now and I was wondering what I can do to speed it up. It's
currently at 170000, and if I try to restart the computer the login
screen will not load if I skip the disk check. Thanks.

It's now finished, but when I start the computer the login screen will
not load.

Did you initiate chkdsk to run during the boot process by typing chkdsk C:
/f from within an elevated command prompt window?

If not, the operating system has detected disk errors and has initiated an
automatic "consistency" check. I have seen this, and in three cases the hard
disk was too far gone to be able to be repaired. The disks had to be
replaced.

Nope I didn't, the operating system detected them by itself. So what do
you recommend I do?

Thanks

Also what causes these Disk errors?

Obtain the hard disk test utility from the manufacturer of your hard drive -
not the computer manufacturer. Run the test. If the drive is still under
warranty (usually 3-5 years) the manufacture will supply you with a
replacement drive based upon the test results.

Of course, you will have to copy over all of your personal files from your
backups to the new drive. You do have backups, right!

Disk errors can be caused by defective sectors or from failing electronics
contained in the hard drive.

A good cause of defective sectors is banging a computer tower with a vacuum
cleaner while it (the computer) is running. The shock can cause the head to
crash into the spinning platters, physically destroying one sector, or more,
in a flash. This is a good reason to get the tower off of the floor and onto
the desk.

Yes I have backups. Okay I'll give them a call tomorrow, and it's a
laptop so I don't think it's been hit by the vacum. Thanks a lot for
your help, greatly appreciated.
