So now I feel at least some Windows Updates do, some antivirus companies like AVG, and Satrow mentioned Macrium (Reflect). I don’t know, other than it happens maybe once a year by Microsoft Updates.
PKCano asked what update could have done this.
I believe the person had to reinstall Windows 7 to fix his issue. I did see where one person was having error messages because the System Reserved was too full. As I mentioned I know it is not a performance issue, it just bothers me, like a scratch on the fender of a car that most people do not see. I am not “worried” over the fragmentation, I just want it to be zero. There were quite a few people wanting a solution as I. When I was researching this last year, I heard people mention that. The Surfing Pensioner says, “You’re worried about 9% fragmentation? My System Reserved is 58% fragmented and has been for at least the last two years! Windows Defragger sees it and claims to have defragged it every week…”. Hello and thank you all for responding PKCano, Anon, NetDef, Satrow, Surfing pensioner, EK, Oscar and PaulT. This reply was modified 3 years, 2 months ago by ek. If it’s actually a solid state drive then it makes even less sense to defrag the reserved partition. So, even if you did somehow defrag the 100MB reserved partition you wouldn’t see any real performance benefit. Think about it: with such a tiny 100MB partition and only 25mb of data involved you’ll get 8% fragmentation with just one or two fragmented files that are a few MB in size.īut, even more fundamentally: the entire 25MB on that partition will be read into the drive’s on-board cache after just a few spins of the platters (most modern mechanical drives have on-board cache >= 32MB). If you were talking about a much larger partition and several GB of data then defraging might make more sense.
So, it’s a 100MB partition with 25MB of data stored? Absolutely no need to defrag in my opinion. Thank you for your comments, they are appreciated. It would be nice if Systernals would make a program for this, but I am wishing. Yours Netdef was the only one even remotely reasonable seen out there at the time. Back about a year ago I did a lot of searching for an answer. NetDef has a good idea, but I don’t think it is the inability of the Windows defragmenter to see the drive, it is more that it will not do it, even though it looks like it is by its % done screen. I also have noticed that some AntiVirus makers use that area, AVG. Not every time but it seems maybe once a year with a special update that is done by them. PKC, I believe it is a Microsoft Update that occasionally makes a change there. But afterwards it is still on X% fragmented (9% as of yesterday). The Windows Disk Defragmenter does see the partition and does have it in the list to defragment, and will try to defragment it.
Windows Disk Management said: Volume-SYSTEM RESERVED, Layout-Simple, Type-NTFS, Status-Healthy (System, Active, Primary Partition), 100 MB. The computer has one (1) drive internally.
I am rather technical, knowing how to work on a computer both hardware and software. But if you say it is common and no ill effects then I might do it. I am a little worried on “making and deleting” a drive letter for a partition. NetDef, I had seen that idea in the past on the web. PKC you are right on with your assessment of that Partition. I did not think about the OS because I was more focused on the actual “System Reserved” partition itself rather than the OS. Hello and thank you all for responding PKCano, Anon, and NetDef.
I don’t want to install a defragmentation program just to do this, hoping there was a stand alone program similar to PageDefrag Systernals makes. Systernals does have PageDefrag and a special single file defragmenter program “Contig”, but I did not find anything to deal with a single partition from them. Yes I know fragmentation of such a small rarely used partition is not impeding performance, but I want it 0% fragmented just the same.ĭoes anyone know of a program that would defragment this “system Reserved” partition? The partition is around 100 megs total with 25 megs of data is in it. Therefore some data is occasionally written to this reserved area. It was 8% prior to the July 2019 updates. I have the partition called “SYSTEM RESERVED” that had been 0% fragmented for years, but has now slowly crept upwards and is currently at 9% fragmented. I do regular maintenance, cleanup and defragmentation. I like to have my computer in good, “spic & span” shape. PKCano, Microfix, Abbodi86, and NoelC, Canadian Tech, could you give this some thought? Hello, I would like to have some of the Askwoody MVPs and posters take a look at this and maybe come up with an answer.
