simply formating means to remove data from a particular drive
see there are two types of format ...
1 quick format
2 complete format
when u use quick format all the data will be deleted only however system files remain unaffected but when you use complete format
it will remove data as well as system files...
so may be because of this ...

correct me if i m wrong...
Thank you

suppose ,say E:drive,i have formatted...
then if before formatting the size of the E drive is 20.23GB then why after formatting it becomes 20.13GB or something like that?What happens to that 0.10GB?
so thanks for your answer but the curiosity still persists!
Eagerly waiting for your posts!

Sorry i couldnt get it now too...
let me be more clear with the question..
say the total size of a drive is 20.23GB..
now i have some data on that drive and say it occupied 19GB..so i have free memory space of 1.23GB..
then after formatting the drive ,the data will be lost ....but the size of the drive should be 20.23GB(as expected)...but after formatting the size decreases...means the total size now becomes 20.13GB(say).....it doesnt remain 20.23GB...why???😕
And what happens to that 0.10GB??

Hope my question is clear now!!
Eagerly waiting for your posts!

Happy Durga Puja!

Is it often happens in your computer
or 1st time you see it
if 1st time then my be you system files may be affected by virus and after formating virus has been removed...so it happens
otherwise i don't think so any reason behind it

Every drive maintains a inode value for every sector, size of a sector is normally 1kb. These inode values are stored in a tabular form. When you cut,copy or paste, these inode values are used by the process to do the specific work. This inode table took away your 100mb from 20gb. Its not unusual, its the way the drive are designed. More the size of drive, larger will be the inode table.
In linux you can see the inode value of file, by using command >ln -l <filename>
So don't feel weird when drive shows slightly less space than actually you saw before formatting.

hello...
Thank you so much for your answer...
Now can you share some more ideas on inode values?
And how to see the inode value of a file in Windows XP?:smile:

hey vik
I agree that this concept of inode exists in unix as well as linux? but
does this concept of inode exists in windows..??

😕😕😕

Concept remains same, a drive (according to the filesystem such as ntfs,fat32,ext3) takes some amount space for file indexing, storing various read/write/execute rights of users, various attributes of files such as hidden,read only, name of file, sectors occupied, owner of file, date create/modified etc.

I don't think, in windows you can see such that, because windows is not flexible enough. Thats the difference between windows & linux.
There may be some software which do such things in windows.
