Solve : a white space in defragged drive? |
| Answer» <html><body><p>Hello<br/><br/>When HDD drive like D, E, F, and so on (and not C as root drive) defragged whit "Disk defragmenter", a <a href="https://interviewquestions.tuteehub.com/tag/white-248352" style="font-weight:bold;" target="_blank" title="Click to know more about WHITE">WHITE</a> space appear in the middle of drive. Both side of this space are used and are blue.<br/><br/>What this mean? <br/>Why this space not filled?<br/><br/>Thanks<br/><br/>[recovering disk space - old attachment deleted by admin]Swapfile...don't worry about it.this white space is not swap-file. it's free space.<br/>swap-file is green and by default located in root drive (C:).<br/><br/>but this space does not filled by files (blue section)<br/>why?Quote from: k_mohsen on August 21, 2010, 11:56:11 AM</p><blockquote>this white space is not swap-file. it's free space.<br/>swap-file is green and by default located in root drive (C:).<br/><br/>but this space does not filled by files (blue section)<br/>why?<br/></blockquote>It was, and now it's not. Windows fragments the instant you exit Defrag. It could also be space marked as "bad" or unusable.<br/>Try this one: <a href="https://www.piriform.com/<klux>DEFRAGGLER</klux>">http://www.piriform.com/defraggler</a>So it's free space. Unless your defrag utility has an option to consolidate free space there's nothing you can do - nor is it important.I haven't used the standard Disk defragmenter in Win XP for quite a long time but doesn't it have a color code guide at the bottom of the Disk defragmenter panel whch tells you what the colors represent? Quote<blockquote>this white space is not swap-file. it's free space.<br/>swap-file is green and by default located in root drive (C</blockquote><br/>And how do you know this ? ?<br/>Different apps may show it differently...Try defraggler as Computer_Commando recommended. It gives you more information than the standard Windows defrag.NTFS <a href="https://interviewquestions.tuteehub.com/tag/partitions-1148200" style="font-weight:bold;" target="_blank" title="Click to know more about PARTITIONS">PARTITIONS</a> use a file allocation table called the Master File Table. An NTFS partition keeps a backup copy of the most critical <a href="https://interviewquestions.tuteehub.com/tag/parts-239415" style="font-weight:bold;" target="_blank" title="Click to know more about PARTS">PARTS</a> of the MFT in the middle of the disk. This reduces the chance that a serious drive error can wipe out both the MFT and the backup copy. That small, unmovable chunk in that you see is the backup MFT.Quote from: JJ 3000 on August 21, 2010, 11:02:11 PM<blockquote>NTFS partitions use a file allocation table called the Master File Table.

Last time I checked NTFS didn't mark it's data structures as free space anyway. That would be pretty stupid.<br/><br/>As Allan <a href="https://interviewquestions.tuteehub.com/tag/stated-3074404" style="font-weight:bold;" target="_blank" title="Click to know more about STATED">STATED</a>, unless you have an option like "consolidate free space" selected, the defragmenter is not going to consolidate free space. Therefore you will likely have bits of free space that don't move.<br/><br/><br/><br/>Yeah, he's right. Green = unmovable. White = free space. I don't know what I was thinking. It's been a while since I've used the defragmenter.<br/><br/>Thanks BC Quote from: BC_Programmer on August 23, 2010, 07:53:29 PM<blockquote>...Therefore you will likely have bits of free space that don't move.<br/></blockquote><br/><br/>maybe this free space, reserved for windows defragmenter's task.<br/>but you can see this free (or white ) space in other free drive.<br/><br/>if you search "Diskeeper" or "Defragmenter" in google image, you can see this space be in second cylinder in HDD.<br/><br/>[recovering disk space - old attachment deleted by admin]Quote from: k_mohsen on September 03, 2010, 03:20:48 PM<blockquote><br/>maybe this free space, reserved for windows defragmenter's task.<br/>but you can see this free (or white ) space in other free drive.<br/></blockquote>Huh?Quote from: k_mohsen on September 03, 2010, 03:20:48 PM<blockquote><br/>maybe this free space, reserved for windows defragmenter's task.<br/>but you can see this free (or white ) space in other free drive.<br/><br/>if you search "Diskeeper" or "Defragmenter" in google image, you can see this space be in second cylinder in HDD.<br/></blockquote><br/>OK, if you're using a optimizing type of defragmenter then that would be by design.</body></html> | |
