loki_rising Posted January 13, 2002 Share Posted January 13, 2002 I have a 20gb had drive format as a 19gb. I was looking at my free space and it showed 6gb have been used, but i went and got the properties of all of the files and folders (including the hidden and system) and found it was only using 4gb. So any buddy know where the other 2gb is? Is it a bug in my Maxtor drive, in XP, in my install? Anybudy have this problem before? Link to comment Share on other sites More sharing options...
[saint lucifer] Posted January 13, 2002 Share Posted January 13, 2002 It happends when you format your drive. NO ONE ever gets their full space. Link to comment Share on other sites More sharing options...
ahodes1 Posted January 13, 2002 Share Posted January 13, 2002 but you NEVER lose 2 GB on a format... maybe 500 MB but not 2GB... run chkdsk /F and see if it makes a difference... Link to comment Share on other sites More sharing options...
simms Posted January 13, 2002 Share Posted January 13, 2002 Doesn't it depend on the cluster size and partition you make it to? That's a bonus of NTFS, right? Cause then you can have smaller clusters...or something like that :p Link to comment Share on other sites More sharing options...
mtgriffith Posted January 13, 2002 Share Posted January 13, 2002 (including the hidden and system) Are you sure you had your page file selected? Link to comment Share on other sites More sharing options...
loki_rising Posted January 13, 2002 Author Share Posted January 13, 2002 my page file was selected and counted. it is ntfs by the way Link to comment Share on other sites More sharing options...
Chrissssssss Posted January 13, 2002 Share Posted January 13, 2002 You should get two sizes, "size" and "size on disk" What do each say? Unlikely that you'd lost 2GB with NTFS unless you have LOADS of files Link to comment Share on other sites More sharing options...
Weasel Posted January 13, 2002 Share Posted January 13, 2002 Can someone explain to me the difference between "size" and "size on disk"? I've never understood that. Link to comment Share on other sites More sharing options...
loki_rising Posted January 13, 2002 Author Share Posted January 13, 2002 the size and size on disk were relatively equal + or - a few megs. Link to comment Share on other sites More sharing options...
ahodes1 Posted January 13, 2002 Share Posted January 13, 2002 Originally posted by Weasel Can someone explain to me the difference between "size" and "size on disk"? I've never understood that. Size: Actual space that the file's data uses. Size on disk: The actual space the file uses + wasted space from "slack" on the disk due to a file not using the whole cluster.

mtgriffith Posted January 13, 2002 Share Posted January 13, 2002 Out of curiosity I right clicked on my c drive and picked properties. It said I was using 5.19 GB. Then I opened my c drive, selected all files (including hidden and system), right clicked and picked properties. It said there was 4.24 GB in files and folders. Hmm.

Chrissssssss Posted January 13, 2002 Share Posted January 13, 2002 Hmm, just tried it myself. The properties of the drive says 19.3GB used With all files selected space used is 17.4GB Could it be the MFT? Link to comment Share on other sites More sharing options...
ahodes1 Posted January 13, 2002 Share Posted January 13, 2002 Mine was 2.46 GB used, highlighted all files and got 2.33 GB used... also make sure you uncheck "Hide Protected Operating System Files" for an accurate look. Also run chkdsk /F as it will fix some bad counts and free unused indexes, and clean up the drive as well. Link to comment Share on other sites More sharing options...
PM5K Posted January 13, 2002 Share Posted January 13, 2002 Size is the actual space a file takes up. Size on disk is how many clusters the files take up. Also I get 18.64gb after a format, that's with FAT32. Link to comment Share on other sites More sharing options...
loki_rising Posted January 13, 2002 Author Share Posted January 13, 2002 done that and did a chekdisk twice. still same. funny thing i had a stop error 0x0A both times after the reboot after the check disk. Link to comment Share on other sites More sharing options...
Chrissssssss Posted January 13, 2002 Share Posted January 13, 2002 I'm guessing it's the MFT, maybe anyways. You wouldn't be able to select that in Explorer Link to comment Share on other sites More sharing options...
mtgriffith Posted January 13, 2002 Share Posted January 13, 2002 I confirmed that "Hide Protected Operating System Files" was unchecked and I did a chkdsk /f. No change. Link to comment Share on other sites More sharing options...

ahodes1 Posted January 13, 2002 Share Posted January 13, 2002 chrissss is probly right its the MFT, security descriptors, indexes, etc. and also the overhead of the format in general... expect to lose some space.. but not 2 GB! Link to comment Share on other sites More sharing options...
Chrissssssss Posted January 13, 2002 Share Posted January 13, 2002 Depends how big your HD is really. 2GB on a 40GB drive, happening here as well, this is a 40GB drive. Hmm Link to comment Share on other sites More sharing options...
mtgriffith Posted January 13, 2002 Share Posted January 13, 2002 0x0A is a hardware problem. It usually means bad RAM. Link to comment Share on other sites More sharing options...
Erichiwaann Posted January 13, 2002 Share Posted January 13, 2002 There are two different number systems which are used to express units of storage capacity; binary in which a kilobyte is equal to 1024 bytes, and decimal in which a kilobyte is equal to 1000 bytes. The storage industry standard is to display capacity in decimal, but some programs measure the capacity of a drive in binary. Measurement Binary Decimal Kilobyte (KB) 1,024 1,000 Megabyte (MB) 1,048,576 1,000,000 Gigabyte (GB) 1,073,741,824 1,000,000,000 Terabyte (TB) 1,099,511,627,776 1,000,000,000,000 Link to comment Share on other sites More sharing options...

Weasel Posted January 13, 2002 Share Posted January 13, 2002 So how do you know which one to use in certian situations Erichiwaann? For example I know that Coolmon uses the binary method so one must device by 1024 to get correct conversions betweek KB and MB Link to comment Share on other sites More sharing options...
Chrissssssss Posted January 13, 2002 Share Posted January 13, 2002 What does that have to do with losing space though? Link to comment Share on other sites More sharing options...
