free space 2 GB loss after disk defrag

Cannot explain losing so much, instead of gaining. My restore point in SR remains just one and there is less than 4 MB of deletable files in Disk Cleanup(as usual). What happened?

Could be a potential shadow copy. What defragmentation program did you use?

Also defragmenting a HDD will not gain any free space itself but rather just moving files so it can be read more quickly by the HDD needle head.

Hi Josh...in the past, after defrag i either gained at least 1 GB...or no gain. But never lost, never mind 2 GB loss.

I have always used Auslogic defrag. (Vista defrag takes way too much time).

Normally a disk defrag would not change disk free space at all. That is not it's purpose and it should not happen. If it does the file system may have problems. Check this with chkdsk at the command line.

I had something similar happen with one version of Puran Defrag. I "lost" a bunch of free space. Evidently there was a glitch that didn't dispose of the shadow copy it makes in case a file needs to be recovered due to a falty move etc..

I backed off to the previous version of Puran until the next update, to side-step the issue. Whatever you are using to defrag, try something else. To get rid of garbage shadow copies you can turn retore points off, then back on. Also a good idea to use an image backup and have one in reserve anytime you kill all your restore point though.

edit: also note that in Vista if you turn off restore points, then turn them back on, the storage max will be reset to the default 15%. To set to annother value use the vssadmin command in an Administrator command prompt. It's been detailed many times on this forum so a search should give the details of the command.

Another thing you could do is download Shadow Explorer. It's a freeware that lets you extract individual files from shadow storage. The interface is just like an undelete program. You can look through the storage with it and see if you have tons of duplicates or other strange things.

The missing 2GB is recovered and I am not sure how.

One thing I had done was click ADVANCE TOOLS from Performance info and Tools window(I was trying to update my score) and I was informed that one NVDIA graphic driver was slowing me down and should be uninstalled if no longer being used. I located the driver in Device Manager and had it uninstalled.

But this extra driver had alwas been there. So I am not sure its uninstallation was the reason for the 2GB recovery.

It is possible that the uninstallation created a system restore point which removed the shadow copy that took up the 2GB however I cannot be for certain.

I always wonder why some restore points are bigger sized than others. RP's are usually 1GB but sometimes they can be as large as 4GB.

Once I was going nuts for being 4 GB short with just one RP in System Restore; so, curiously I created a restore point that allowed me to delete the previous RP. And as I suspected that particular RP deletion instantly restored the missing 4GB.

But I still cannot explain why Disk defrag cost me 2 GB.

As miles said it would most likely be the program that you're using. Try to temporarily try a different program to see if it still affects free space.

Click to expand...

Even larger if you have video files. Sometimes I would forget to delete DVD image files when done with them. A few of those can create really big restore points. :)

edit: if you haven't recovered the shadow copy space already I recommend the method of turning System Restore off, then back on, as the safest. A 3rd party program might get confused by shadow copies that are corrupted or not correctly saved.

It seems not all restore points are the same. Some are 4GB while most are 1GB and others are in-between. Manually created RP's are 1GB. Automatically created RP's after software /hardware/program installation or deletion are bigger sized...as big as 4GB.

So...it seems 2GB loss after defrag is due to automatic RP it creates.
