Consolidating NTFS free space

Posted by jpluimers on 2017/12/29

For shrinking VM disk images, it’s important to consolidate NTFS free space towards the end of the this.

I’ve tried many tools, starting with defrag C: /X (which tries, but doesn’t give good results) and found out these steps give the best results:

  1. Perform an Ultradefrag full optimisation,
  2. Perform a MyDefrag Consolidate free space script on the drive.

If shrinking still fails then:

  1. Try the Ultradefrag at boot time
  2. Verify what kind of file(s) prevent shrinking: they show up in red after the MyDefrag session:
    1. Zoom in them (they can initially as small as 1 red pixel) by clicking on or near them, repeating the zoom long enough so you can hover over with the mouse and the lower part of the screen shows a filename like  where you cannot find much information about “$badclus:$bad:$data” but appear to be clusters marked as bad on NTFS level using something like chkdsk /B.
    2. If it was a bad sector like above, then try to resolve it with [WayBackntfsfix which ships with GParted live boot:
      1. boot a [WayBackGParted — Live CD/USB/PXE/HD drive,
      2. run GParted to see the drive path (for instance /dev/sda1)
      3. start a terminal
      4. run this command:
        ntfsfix -b /dev/sda1
        which will give output like this:

        Mounting volume... OK
        Processing of $MFT and $MFTMirr completed successfully.
        Checking the alternate boot sector... OK
        NTFS volume version is 3.1.
        Going to un-mark the bad clusters ($BadClus)... OK
        NTFS partition /dev/sda1 was processed successfully.
      5. boot back into Windows
      6. on an administrative command prompt run this for the affected drive letter:
        chkdsk D: /B
        (reboot if needed)
  3. Shrink the drive using diskmgmt.msc

If you still cannot shrink, then try [WayBackhttp://ftp.raxco.com/pub/download/pd14.0/pd14.0_pro.exe PerfectDisk by Raxco free trial.

Note:

MyDefrag (formerly named JkDefrag) is not maintained any more but the 4.3.1 version in the WayBack machine still works very well as the underlying defragmentation APIs in Windows haven’t changed.

Task Scheduler – command-line End a Running Task

Posted by jpluimers on 2017/12/11

schtasks /End [/S <system> [/U <username> [/P [<password>]]]] /TN taskname

[WayBackEnd a Running Task

Every now and then you have those Scheduled Tasks consisting of batch files that – despite trying – still ask for user input.

If – even after a reasonable time out – the Task Scheduler still hasn’t killed them, you can kill them by hand with the above schtasks in a snap.

How to Easily Print a Large Image to Multiple Pages in Windows | Scottie’s Tech.Info

Posted by jpluimers on 2017/09/04

Many applications cannot not do that (Paint.net is one of them), but Paint can at least in Windows XP, 7, 8. and 8.1 (I need to check other Windows versions).:

In any case, here’s what you do:

  1. Open the image you’d like to print in Paint
  2. Select: Print -> Page Setup (Vista and 7), or File -> Page Setup (in XP)
  3. Under Scaling, select Fit to and change the setting to something like “3 by 2 page(s)”
  4. Click OK
  5. Print the image from Paint, and make sure to select “All Pages”

Note the “3 by 2” has the order “horizontal by vertical”.
