Workaround “Running chkdsk in Read-Only mode” on Windows XP

Tuesday, July 16th, 2013

running chkdsk in read only mode microsoft windows  XP chkdsk schedule check drive C on next restart

I had to fix old Notebook Dell Insspiron 1501 (890 mb ram and 1.60 Ghz CPU) notebook with Windows XP SP2. The notebook looks okay but as it is an old piece of hardware I decided to check hard drives for bad sectors with Windows (Check Disk) –  chkdsk. 

Running chkdsk via -> cmd.exe does not work because file system is in use and once you run chkdsk it does spit warning and error:


"Running CHKDSK in Read-Only mode
".

Errors found. CHKDSK cannot continue in read-only mode

Because it checks hdd in read-only its check is not completely reliable and in case some bad block is matched it is not possible for chkdsk to write on HDD and try fix or move it to some free space blocks.

 

To work around this its necessary to run chkdsk with options:

chkdsk C: /v /f

This command brings out prompt like in below screenshot offering to run CHKDSK on C drive on next system boot before starting Windows services which does lock files on file system – making it unavailable for CHKDSK to read blocks on it.

The notebook had 3  Drives C:\, D:\ and E:\ so I run above command also on D:\ and E:\ to make sure there are no physical damages on D and E partitions, i.e.:

chkdsk D: /v /f
....

chkdsk E: /v /f
...
.....

Teracopy faster Windows copy or Save files from Windows PC with dying hard drive

TeraCopy logo copy files faster and prevent windows hangs up on broken hard disks
My sysadmin colleague mentioned today about TeraCopy. An application for Microsoft Windows designed to be used to Move or Copy  files. So why would one want to use Teracopy instead of normal Windows Explorer copy integrated soft? Reason is Teracopy is faster than MS Windows Copy / Move and uses dynamically adjusted buffers to reduce seek times. This asynchronous copying speeds up file transfers between physical HDDs.

More precious feature of TeraCopy is whether you have to Save data from hard disks with Bad Sectors, it can skip faulty files (stored on bad sectors) without triggering Windows to hang up or halt with the Blue Screen of Death.TeraCopy even can be setup to replace Windows Explorer (i.e. Shell Integration copy and move functions). Beside that it works well with Unicode encoded file names (Cyrillic, Chineese) etc.

As of time of writting article, TeraCopy has support for all Windows NT (Windows XP / 2000) as well as for Windows 7 and 8. Whether a failure to copy file occurs it tries to recopy file several times in order to achieve copy success. After each file is copied a CRC check up value of file is calculated and matched. It also provides a way more verbose information on copied files than Windows default Copy. It is very useful in copying large files from system to system as file transfers complete time is significantly lower

Once TeraCopy is installed it automatically does replace Explorer Copy and Move functions, hence after install every next Move or Copy operation is auto handled by it. In preferences the user could still revert back Copy / Move functions to Explorer original.

Unfortunately TeraCopy is not-free software but freeware and can only be used to non-commercial use, for commercial use you have to purchase TeraCopy Pro version.
