Defragmentation as scheduled task?
I would like to regularly run defragmentation during night hours.
However, when I program it as a scheduled task, the UI window opens but - since I don't click "Analyze" nor "Defragment" it does nothing and sits there waiting for my input. What option or flag do I have to pass so that it actually starts defragmentation (preferably even if the free space is less than 15%)? Michael |

The Windows XP built-in defragmenter defragments just the files; you end up with defragmented files (they are individually contiguous on disk) but they are spattered all over your disk. JKDefrag (which is free, and nothing to do with me) defragments the files, but also moves them as close as possible to location 0, which is the fastest part of the disk. After I'd run JKDefrag I though my applications were hanging when I launched them, until I realised that the disk accesses involved were almost silent because the files were all clustered together (no pun intended). -- Steve Swift http://www.swiftys.org.uk/swifty.html http://www.ringers.org.uk |

After I'd run JKDefrag I though my applications were hanging when I launched them, until I realised that the disk accesses involved were almost silent because the files were all clustered together (no pun intended). But I would recommend using XP's Task Scheduler to simply schedule it to run with the appropriate flags. As for "because the files were all clustered together", that simply creates more need for more defrags than is neccessary. Fragmentation begins to happen within the first few writes to the disk, where as when there are spaces between the file sets, the OS can more quickly find a place to dop a file. Remember, the registry is being read and written to constantly, so even if you don't create files, fragmentation is going to start happening. I never heard of JKDefrag but if it's any good it will have options for putting things on the beginning, first, mid, last, and the end of the sector lists. Else it's not much good if it only does what you describe. In general, IMO, using a 3rd part app to do what XP can do well natively is just adding more opportunity for problems and corruption to occur both on disk and in memory and in the registry. Perhaps you should research the registry and its use a little? HTH |

Actually - given you claim it is 'the best', and you claimed that first in this conversation - the need for you to explain your claim would come first. Admittedly - in Windows XP itself is a cut-down version of Diskeeper. However - in as many years as I have done this - although I recommend defragmentation as a means of upkeep - I have found none that do their job so much better than the rest as to encourage a purchase of a program to do it. JKDefrag is actually the first defragmentation product I decided to recommend above just using the built-in functionality. Not because it does such a spectacular job above and beyond that of the innate defragmentation utility, but almost entirely because of its screensaver and price (free.) ;-) -- Shenan Stanley MS-MVP -- How To Ask Questions The Smart Way http://www.catb.org/~esr/faqs/smart-questions.html |
