Sorry Louis NO! CHKDSK seems to work OK,
but Your underlaying calculations were wrong.
And the other followons by Acronis, Paragon reflect on CHKDSK results!

So my outcome is: Your HDD has a problem which ist stated by CHKDSK!
You'll have to "repair" the disk before the other utilities will be able to
work correct! I know Your described behaviour from one of my disks, for
which I know that it has sector read (damage) problems.

NO, the datasheets like above tells of
User Sectors Per Drive 234,441,648
which is above Your calculaton!

This (234,439,535) number doesn't come from my calculation, it is the
*partition* last sector number reported by Paragon Partition Manager.

The figure I calculated was incorrect.

Hope this clarifies..

Its likely possible to fix it some other way, but I havent tried.

You could try Acronis Disk Director Suite and see if it will clean the mess
up.

I toyed a little with Acronis, but since I was successful performing a
full backup (using NTBackup) and restoring it on another drive, I
didn't experiment for a very long time..


But here are some things I noted (nb : the drive is mounted as primary
slave and was not the one the PC booted from).

1) Acronis "check partition" option is invoking XP's own chkdsk (with
exactly the same results / error messages)

2) Under Disk Properties / File Suystem / Errors, it says "No errors
were found"

3) Under Advanced / Edit, it shows the following for the first Boot
sector :

Absolute sector 63 (cylinder 0, head 1, sector 1)
File system name : NTFS
Sector size : 512
Sectors per cluster : 8
Reserved sectors : 0
FAT copies : 0
Root folder items : 0
Big total sectors : 0
Media ID : 0F8h
FAT size : 0
Sectors per track : 63
Number of heads : 255
Hidden sectors : 63
Big total sectors : 0
Hard drive : 080h
Reserved : 00h
Reserved : 080h
Big total sectors : 234,439,472
MFT cluster number : 786,432
MFTMrr cluster number : 1,250,053
MFT record size : 0F6h
Index buffer size : 01h
Boot sector signature : 0AA55h

4) clicking on "go to sector" opens the following dialog box :

Absolute sector (63 - 234,439,535)
Cylinder (0 - 14,593)
Head (0 - 254)
Sector (1 - 63)

If I manually enter 234,439,534 as the absolute sector, the 3 other
values change for :
Cylinder : 14593 Head : 47 Sector : 29

Going to the previous sector (234,439,533) gives :
Cylinder : 14593 Head : 47 Sector : 28

But going to the next sector (234,439,535) gives :
Cylinder : ? Head : ? Sector : ?

If I manually enter : Cylinder 14593 Head : 47 Sector : 30
Acronis set the absolute sector to 234,439,535
and shows either an error message ("Failed to read from sector
234,439,535") or (in hex view) a 0x00 filled sector.

you might as well
just delete the partition and replace it with the correct drive type after
wiping anyway.

It's done now.. :-)

BTW, I don't think it is directly related, but ntBackup gave me the
following error when backuping the drive :

"Unable to access portions of folder
E:\Windows\Assembly\GAC_32\System.EnterprisesServices\2.0.0.0__b03f5f7f11d50a3a"
you may not have the rights to open the file or the folder is missing
or corrupted.

If I try to open that folder using windows explorer, I get the
following message (approximate translation) : (folder name) refers to
an unavailiable location. It could be a place on a hard disk of this
computer or on a network. (...) If you still do not find the
information, it may be moved to a different location.

Since this folder's was created after my original post, I believe it is
not the cause of the problem.


Thanks for your input !
