Please send me the results of the chkdsk
That is start
control panel
admin tools
event viewer
on left pane click application
when that log loads on the main pane click the source heading once
that will sort them and you then scroll to the winlogon entries
open by double clicking the most recent winlogon entry and check that it is the chkdsk results from that chkdsk - ie the one you have last run
If it is not of course, check the winlogon until you find the right one
Then click the double page symbol ONCE to the right of the broad up and down arrows
now paste either directly to your reply, or paste to wordpad etc and then copy and paste to here please as the actual log, not as an attachment that I have to open.

1. That chkdsk reported

4 KB in bad sectors

you will notice if you read the details that this 4KB which is 1000 bytes in a KB is also reported as the same size as an allocation unit

4096 bytes in each allocation unit

that is because in that regard there are 1024 bytes involved.

2. It is not quite as minor as it may first appear - when you see that you have

39062015 KB total disk space

a 40 GB Hard drive - eg. 1000 KB in a MEGABYTE and 1000 MB in a GIGABYTE

3. On the hard drive there is something called the Master File Table if a bad sector occurred in the Master File Table, which is what tells the drive where to look for each file it needs, it may well prevent Windows from loading fullyOR at Least problems after it does.

If the bad sector occurred in the first block of the HDD it may even prevent the system going past the BIOS post stage

Basically when you boot the computer this is what happens

As with other Windows Operating Systems, when you turn on your PC, it goes through an elaborate boot up process. It begins when the computer performs the POST (power-on self test), followed by the POST for each adapter card that has a BIOS, for example, your video card. The BIOS then reads the MBR (Master Boot Record) which is in the first sector of the hard drive and transfers control to the code in the MBR which is created by the XP Setup. This is where Windows takes over the startup process.

Here's what happens:

  • The MBR reads the boot sector which is the first sector of the active partition.
  • Selecting XP from the boot menu causes Ntldr to run Ntdetect.com to get information about installed hardware. Ntldr then uses the ARC path specified in the boot.ini to find the boot partition. The one where Windows XP is installed.
  • Ntldr, then, loads the two files that make up the core of XP: Ntoskrnl.exe and Hal.dll.
  • Ntldr reads the registry files, selects a hardware profile, control set and loads device drivers, in that order.
  • Then, Ntoskrnl.exe takes over and starts Winlogon.exe which starts Lsass.exe (Local Security Administration), this is the program that displays the Welcome screen (If Professional Edition-the Windows Log On dialog box), and allows the user to log on with his/her user name and password.
4. So now you can see that, the small proportion of the drive reported as bad sector may have been the cause of the problem
As my recommendation to run the CHKDSK a second time - then allowed you to boot into Windows. -

If chkdsk reports it has found errors and repaired them, you should depending on the error report always run it again, especially where you are trying to resolve a loading error.

5. Chkdsk /r does not repair BAD SECTORS, in fact no disk check / repair - can actualy REPAIR bad sectors, if they are really failing sectors of a HDD
It simply attempts to recover the data from the bad sector re-write it to a good sector and then mark the original sector as BAD so that data is not re-written to it

6. My recommendation is that you ASAP make a complete image of that drive
XP does not allow you to do that with the included software as easily as Windows 7.
I would use one of the free programs on offer.
There are many - sse item 9 below



I have used those, they are easy to follow and have good guides to them. - for instance

7. You have to remember that a mere backup eg. a copy of your files etc will NOT allow you, if that drive does fail to then have a system that has all the programs installed that you do now
You cannot preserve programs by means of a simple backup - they will not work
So unless you have the installation media they are gone.

8. I would then keep a close watch on the situation and IMMEDIATELY you start to experience errors AND/OR the bad sectors increase I would consider replacing the drive.
Further advice can be given when you post.

DO NOT repeatedly run the chkdsk /r, as that itself stresses the drive and may indeed do more harm than good.
I would say -run it as soon as you have problems AND even if no problems run it once a month.

9. I mentioned above there are many FREE imaging programs for HDD`s




10. I always think it is best to try and offer you a full explanation.
I have tried to keep it is easy to follow as possible
I hope you do not find it confusing.

While you read the details I will look at the CLEVO site, but if you KNOW the make and type of HDD please post it.

The drive is as I am sure you know a 40GB IDE (PATA) drive - therefore you must if you are faced with the need to replace, enure you do not buy a SATA interface connected drive.

Futjitsu sold their drive business to Toshiba in 2009, so you will not now be able to purchase a Futjitsu drive, but that does not matter, it is the size and interface that matter.

and they provide for Futjitsu branded drives a disk check

Use the DOS one, it is better to run it outside of the actual window O/S

Finally if it does require replacement, now or later, the user manual. guide for the Clevo will I am sure help. On many occasions it is little more than 2 screws to remove a panel on the laptop base and disconnect the drive. On some it is more involved

Here is the Clevo link

Good luck
