Solve : missing gb from every partition? |
|
Answer» i have three partitions, and on every one, the size of all the files is smaller than the used space on the disk, up to 3 or 4 gb, including hidden folders. what could be wrong?Some space will be taken by boot blocks, etc.i'm using win xp sp2. what are boot blocks? Information required to boot the OS. There is also space used by the file system to store the file location on the the disk. Then there is the matter of overhead. If your disk is formatted with 8k sector size, a 1k file will use 8k of space since that is the smallest segment that can be used. Check out the calculations that Mac posted above and you will see that there is no missing space. Quote i'm using win xp sp2. Just to check. Is the drive formatted to FAT32 or NTFS? If you type - cmd - in the Run window and then type - CHKDSK - with no /f switch, do you see 4096 bytes in each allocation unit and is there any mention of bad sectors? E.G. sorry for the late response it's ntfs i have 0 kb in bad sectors yes, there are 4 kb in each alocation unit. what are they? and why 4 kb?4KB or 4k is the standard NTFS format. Is it the System Restore information which is taking up space? Do you save a LOT of files which are smaller than 4KB? If you have a 6KB file then it will take up two 4KB allocation units. But if you have a 2KB file it will take up just half of one 4KB allocation unit. If an entire partition is GIVEN over to 2KB files you'll lose 50% of the space.i get your point. i save a lot of website links in new NOTEPAD documents, though i don't think there are any more than 50. and they're all on one partition. plus, for 2 gb of space, there have to be a heck of a lot of them. so i doubt it's this. isn't the system restore on the main partition? and how do i check how much space it takes, i can't FIND any files that hint to this. could it be anything else causing this, like system files that grow in space over time?You can get to the System Restore settings via Control PANEL, System, System Restore, and then click on the Settings button. As you can see I have the XP installation on drive C: only monitoring drive C: What you can't see is that I have the XP installation on drive D: only monitoring drive D: |
