    Master File Table ($MFT) size and speed


    Hello.

    Is there any relation to access speed and $MFT size?

    I am wondering because when you have one big partition only (C drive) the $MFT can grow pretty huge.

    I have seen $MFT sizes ranging from 600 to 1000MB in size. Is the $MFT loaded all the time in memory?

    Does its size affects speed? If so, is there any way to shrink it (GPT Partition style)?

    :)

    The master file table's (MFT) BITMAP attribute is incorrect.

    CHKDSK C: reports the following:

    The master file table's (MFT) BITMAP attribute is incorrect.

    The Volume Bitmap is incorrect.

    Windows has checked the file system and found problems.

    Please run chkdsk /scan to find the problems and queue them for repair.

    After running CHKDSK C: /scan I ran CHKDSK C: again and got the same result as above.

    It seems CHKDSK cannot resolve the master file table's (MFT) BITMAP attribute error.

    How do I fix the MFT bitmap error?

    Master file table (MFT) usage at 100%

    No need to worry, system tries to keep a free space just after MFT - so called MFT zone - to keep MFT non-fragmented if there will be needed to increase it size. In addition, small MFT fragmentation does not have noticeable negative effect.

    Hi,

    MFT zone has nothing related with MFT size.

    Please, describe your problem with more details.
