    Hello all!

    In another thread, Johanna has been given the advice to get Partition Magic to solve a problem. This made me wonder:

    With one single partition on a large HDD, say 120 GB, the OS has put a copy of the Master File Table in approximately the middle of the space. There is a reserved MFT zone of 12.5% of disk space which equals 15 GB. In addition to that, it seems to me like XP spreads things over the whole disk.

    If someone has used 4 GB of the space and wants to create a C: of 12 GB, a D: of 72 GB and a E: of 36 GB, how does Partition Magic handle that situation?

    I mean ...... :confused: ...... a lot of "stuff" that should belong to the new C: must be in the space occupied by the new D: and possibly even the new E:.

    Thanks for Your time,
    Christer

    Chtister,

    I have watched the 'DOS' screen which appears on boot when PM is in action making partitions and it is fairly clear that the relevant 'stuff' is moved to the appropriate area of the HD.

    Hi Pete!

    I was almost convinced that it was moving things around. It probably recalculates the reserved MFT zone to satisfy Windows as well.

    I´ll have another go at finding a PM tutorial but if I don´t find one ...... :eek: ...... I´ll probably be back with follow-up questions!

    Hi Christer

    Speaking of XP and scattered data.

    I just looked at my C: drive which is 6.12gig. ( 2.64gig free ) and XP has stuff scattered from beginning to end and none of it seems to move when I defrag.

    Hi BillyBob!

    I have never seen a fresh install of XP on an OEM computer but once. It was on a 40 GB single partition HDD and it was scattered all over.

    The XP defragger moved most of it towards the front of the HDD but not everything and it didn´t get into a contigous chunk. I do however not think that it is meant to.

    What I am pondering is, if the owner gets say 15 GB of "data" spread over his 40 GB HDD and wants to use Partition Magic to create a C: of 10 GB and a D: of 30 GB ...... :confused: ...... how does PM handle that when it doesn´t fit on the first partition?

    Does PM go by the Master File Table and put certain folders on the second partition?

    How does PM "split" the MFT?

    I know questions - questions - questions,
    Christer

    It doesn't work that way. You have to do that sort of thing manually (so to speak). You'd have to do it in a two step process. First, you'd create two partitions keeping the C: drive large enough to hold all the data that's currently on the drive. Once it finished, you'd boot back to windows and then copy the necessary amount of data (whatever it takes for you to be able to make the c: drive 10 gb) to the new d: drive. Then you'd use partition magic to resize the partitions to the size you wanted. There's really no way the program can do this for you. It has no way of knowing which data to move to the d drive.

    I've used Partition Magic once or twice on someone else's computer. Version 7, I think. Seemed pretty easy.

    It first analyses your hard disk and then presents a GUI window, very similar to the Disk Management window. You slide the borders of the rectangles (representing the partitions) to resize it. There is a maximum and a minimum you can resize. When you're satisfied, you click go or start or whatever.

    During the process, it moves the data to the front of the partition and then changes the partition table data and whatever else need changing to resize the partition and then it's done. I think.

    A reboot may be needed but I don't remember. I may forget a few other things too but that's the gist of it. Like I said, it seemed easy to me. And, of course, it always reminds you to back up in case something goes wrong and you lose everything.

    At that time, I was using Win98SE on my computer and I used a DOS program called FIPS.

    Zander,
    Then it isn´t Magic ...... :D ...... well, I suppose that there are limits to everything!

    If the purpose is to create a system partition and a data partition, then the simplest way, as I understand it, would be to start by defragmenting and splitting in halves. Next step, to transfer everything "data" off the system partition to the other and defragmenting. Finally resize to 10 GB - 30 GB and defragmenting.
    To get multiple partitions, it would be a repetitive process.

    leelee ...,
    That´s how I would learn about PM too ...... :rolleyes: ...... on someone elses computer!

    Jokes aside, it seems simple enough with the GUI. I assume that it shows used space and free space but despite the fact that PM moves things, I would defragment to make the data as contigous as possible.

    Thanks to all,
    Christer

    Here is more info than you'll probably ever need about Partition Magic. These are PDF's so you'll need Acrobat Reader. HTH

    Thanks, Mr.B!

    They will come handy if or when I decide that I have the need for PM.

    I am, however, a firm believer in planning and doing it right from the beginning ...... :eek: ...... but one never knows. I have a few friends with OEM machines and large single partition HDDs.

    PM does it very slowly.

    If you ever do it, I highly recommend that you do it ONE at a time. The less tasks the better. Create a single partition at a time.

    When the "back" partition has some data, it takes forever. When the back partition is empty, it's pretty quick.

    Ha ha ha! Be glad they are not relatives!

    Anyway, thanks for all the advice, everyone. I gave him Partition Magic a few months ago, and I sent him the link Mr B provided. Like Christer, I have never needed PM because I do my partitions from installs- but these huge OEM harddrives are becoming more common, so I guess I'd better learn how to do this! I think he should split his one partition for XP with PM, then use XP to make all the new ones from the non-OS partition he created with PM. Am I thinking along the right lines?

    To that I 100% agree.

    Especially when reducing an existing 80gig space containing the OS and possibly other software.

    Get the process set up and started and then WALK AWAY. Just check once in awhile to see if any error messages have come up.

    And keep the fingers OFF of the keyboard

    If problems do come up PM will let you know.

    And if PM is started from within Windows make sure that screensaver is OFF.
