Bernd, bad sectors can exist on any partition on your laptop disk drive but CHKDSK can only check those partitions which have a drive letter allocated to them, i.e. C: for Windows.  There are normally at least 2 other hidden / system partitions on a disk drive (System Reserved or EFI System, and Windows Recovery partitions) plus there may also be a manufacturers factory reset partition present.  Windows Disk Management will show how many your laptop has.

Dedicated diagnostic utilities from the disk manufacturers take the longest time to complete the checks, but provide the most accurate methods of checking whether the disk is good or needs replacement:

 - Western Digital drives: Data Lifeguard Diagnostic for Windows

 - Seagate disks: SeaTools for Windows

 - HGST disks: HGST Windows Drive Fitness Test (WinDFT)

 - Intel SSDs: Intel Solid State Drive Toolbox

 - Samsung drives: Samsung Magician

 - ADATA drives: ADATA SSD ToolBox

 - Kingston SSDs: Kingston SSD Toolbox, Kingston SSD Manager

 - Transcend SSDs: Transcend SSD Scope

 - Silicon Power disks: SP ToolBox

 - Toshiba disks: Toshiba PC Diagnostic Tool Utility

- Crucial disks: Crucial Storage Executive

The VSS snapshot issue may simply indicate that the bad sector was encountered in an area of the disk that was used to store the snapshot for the backup, i.e. a normally unallocated part of the drive.  You can run the Acronis VSS Doctor tool to check that there are no actual VSS issues present - link is in my signature.

Hello and thanks a lot for help! I really appreciate it.


Hard Disk seems to be a  Crucial_CT275MX300SSD1:

Page not found.

2.) VSS Doctor Tool:

c green ok
red! \\?{3d6251......\300MB of 830 MB free, Minimum storage size 320 MB Free space is below required minimum.
\\?\Volume{...} green ok

your hint seems to be very good!

partition layout:

450 mb recovery / 100 mb efi / 254 gb ntfs start, shadow, primary / 831 mb recovery!

seems there was win 7 installed before and win 10 upgraded home edition,

and recovery partion was not big enough for win10 the old one recovery partition and a new additional one set in the end of partition room...


how to go on now?

assign a drive letter to red marked storage using acronis tool?

delete recovery partions using partition tool under linux?

could i do a recovery to win 10 home still and delete recovery partions afterwars maybe with moving partion with partition wizard tools? data can be lost no problem.

Bernd, the Crucial Storage Executive web page opens fine for me which may suggest they only allow visitors from within the geography for the site.  The link was to the GB page and I am in England, so perhaps try the German Crucial site?

See webpage here for a German version

Try the Crucial tool first on your drive to see what this reports?

Before you attempt to delete any partitions (not recommended)...  try making a series of backups where you select just one partition at a time, to see if you can identify which one is giving the error about bad sectors?

Crucial Storage Executive:

German Page was ok and working, downloaded Tool, installed it:

- hard disk ok!

- firmware updated using tool - ok.

 backup without the 2 recovery partions using acronis 2019... c partition and efi partition.... same error.

i think cause the problem is not solved with the space to store temporarely image Files.

- running only c partition backup - >  same problem.
