    There seems to be so many different opinions if defragging a windows server
    is worth it... especially on hardware raid 5 setups. Ive read quite a few

    I have multiple servers here that have never been defragged in 2 years or so
    running diskkeeper analysis it reports that the server is highly fragmented
    and should be drfragmented asap. some are hardware raid 5 others are just

    should hardware raid 5 setups be defragged ?
    should single drive mirror sets be defragged ?

    also on some servers diskkeeper is reporting that the MFT is 90+% full and
    its size should be increased, does this really need to be done ?

    thanks for any responses

  2. Lets think about this and apply some common sense.

    What does raid level have to do with defragging a drive
    Answer: NOTHING
    Why? Because Raid has nothing to do with files. Raid works at the block
    level and is underneath the file level.

    How do files become fragmented?
    Answer: due to the first cluster available first write rule of disk write
    access files become fragmented as they are written to disk. Its a natual
    process which is why you need to regularly defrag the volume.

    If you don't defrag what's the worst that can happen?
    Answer: you can render a NTFS volume unmountable and inaccessable.

    Why do people confuse Raid with file fragmentation?
    Answer: because they don't understand the difference. Same concept of if
    you have raided drives you don't need to backup. WRONG. Raid doesn't
    protect you from overwritten or corrupted files. Backup and restore does.
    Most commonly used raid levels, if you lost two disks, you lost the entire
    volume. Then what are you going to do?

    Clearer picture?

  3. Oh and what do you think will happen when the Master File Table runs out of
    entry room?
