Fixing “one or more critical volumes is not having enough free space” also known as 0x81000033 during Windows backup

Posted by jpluimers on 2020/02/03

If you get this error:

Backup and Restore failed and you receive the following error message: The backup did not complete successfully. Check your backup: Windows Backup skipped backing up system image because one or more critical volumes is not having enough free space.

then you are dealing with error 0x81000033 which usually means your SYSTEM RESERVED partition is full, but might happen on other volumes you are backing up as well.

Windows tries to trick your mind, as the error actually indicates the disk you make your backup to, but in fact it is about one or more of the disks you are backing up.

Most often, this is the hidden partition SYSTEM RESERVED (sometimes called System Reserved):

The SYSTEM RESERVED partition (~100 megabyte on systems originally installed with Windows < 8 and ~350 megabyte afterwards) contains files relating to boot, recovery and BitLocker drive encryption. You find more information about it here:

The minimum free size for volumes when using Windows backup are these:

  • volumes less than 500 megabytes: 50 megabytes free space
  • between 500 megabytes and 1 gigabytes: 320 megabytes of free space
  • more than 1 gigabytes: at least 1 gigabyte of free space

That was indeed the case on my disk:

Freeing space on the System Reserved volume

A quick search for 0x81000033 reveals space issues usually are about the USN Journal which you can configuring using fsutil.

Even though the documentation doesn’t tell, fsutil accepts not just a drive letter as VolumePath, but also a VolumeName. [WayBack] 1_multipart_xF8FF_3_WolfC07.pdf (Chapter 7 of “Troubleshooting Microsoft Technologies: The Ultimate Administrator’s Repair Manual“) gets that right:

volumepath … specify the path to a logical volume (drive letter, mount path, volume name).

So you do not need a drive letter to disable the USN journal, the volumename suffices.

This volume name is the unique NTFS identification for a volume: [WayBack] NTFS Curiosities (part 2): Volumes, volume names and mount points – Antimail

You can find the volume name inside PowerShell by using Get-Volume | Format-List, then on an administrative command prompt running this:

fsutil usn deletejournal /D \\?\Volume{b41b0670-0000-0000-00e8-0e8004000000}\

In my case this wasn’t enough, so I had to assign a drive letter to see that there was a snapshots directory in the root:

Deleting that directory solved the problem.

When storing huge files under NTFS compression, ensure you have twice the disk space

Posted by jpluimers on 2020/01/31

When copying over a 400 gigabyte file over the network to an NTFS compressed folder on a drive with having 600 gigabytes free space, the volume became full after copying ~350 gigabytes.

What I learned is that compressing huge files for later read-only access is fine, but you need about twice the disk space while the copy operation is in progress.

For non-compressed files you can go without this extra reservation.

Background information:

Note there are also issues with NTFS compression and de-duplication. I’m not sure about sparse files. Be careful when you try to compress the system drive where your Windows OS lives on:

XW6600 WOL – stopped working on Windows 10 – my trusty APC PDU to the rescue

Posted by jpluimers on 2020/01/17

A long time ago I wrote in Mac/PC: sending Wake-on-LAN (WOL) packets « The Wiert Corner – irregular stream of stuff “I’ve succesfully woken up these machines: HP XW6600 running ESXi 5.1 ThinkPad W701U running Windows 7”.

The XW6600 have now been demoted to Windows 10 machines that I only need every now and then, so most of the time they are shutdown.

However, with the installation of Windows 10 however, they stopped reacting to WOL (Wake on LAN).

Per web-search results, I’ve tried all the permutations of the below settings to no avail.

Luckily, my trusty APC PDU AP7921 (and little sister AP7920) helped out: when setting the “Reboot Duration” to 30 seconds or more (so the power fully drains), it can be rebooted.

Note that since I bought these a long time ago, they have been replaced by these:

Firmwares:

Power usage:

  • an XW66000 with 32 gigabytes of RAM and one hard disk takes between 0.6-1.2 Ampère of current, which at 230 Volt is 140-275 Watt.
  • over one day that is between 3.4 and 6.6 kWh

regex – How to write a search pattern to include a space in findstr? – Stack Overflow

Posted by jpluimers on 2019/12/13

TL;DR:

  1. If you use regular expressions (/R) with FINDSTR, then pass them as /C:"regular-expression-string"
  2. If you forget the /C: the string will be used as a normal search string
  3. If you forget the : after the /C you will get an informal error, but the search will continue giving you wrong results

“There was a problem starting C:\Program” “The specified module could not be found.”

Posted by jpluimers on 2019/12/02

If you get this error:

—————————
RunDLL
—————————
There was a problem starting C:\Program

The specified module could not be found.

—————————
OK
—————————

Then it is likely a process trying to run an unquoted path like this:

"C:\Windows\System32\rundll32.exe" C:\Program Files (x86)\ThinkPad\Utilities\PWMTR64V.DLL,PwrMgrBkGndMonitor

Searching did not reveal anything unusual, nor did [WayBack] ProcExp (there were no parent processes), or [WayBack] AutoRuns:

Windows XP Pro won’t boot, safe mode boot hangs at agp440.sys – Microsoft Community

Posted by jpluimers on 2019/12/02

When safe mode is a good thing: [WayBack] Windows XP Pro won’t boot, safe mode boot hangs at agp440.sys – Microsoft Community

During the regular boot, after a minute or so on SSD, a legacy Windows XP SP3 machine didn’t reboot.

During safe mode, it hung after loading agp440.sys. Apparently this is a Good Thing ™ as it means that chkdsk is running in the background as the post above explains.

Nice to know!
