Solved Disk Management - Shrink Partition in Vista

I refer specifically to this Tutorial;
http://www.vistax64.com/tutorials/95398-disk-management-shrink-partition.html

A bit of background first. I have recently had installed a new 320GB Hard-drive to my Laptop [see my Specs]. The allocation of partition [volume] space has been divided evenly between the C:[Acer] - 139GB, and the D:[Data] - 138GB, Drives on the HD.

This is what I have;

Questions;

• Question 1; Is this setup division just the 'norm' for allocating volume space for each drive? In this case it is more or less a 50:50 share of the available space [PQ Service on a hidden partition takes up the rest]....why not 65%[C]:35%[D]?
• Question 2; Is it necessary for the partition volume of the Data drive to more or less mirror that of the Acer drive?
• Question 3; If answer to Q2 is 'not necessarily so', am I then able to partition the Data drive to create a new drive partition of about 60GB, or are there any pitfalls in playing around with this particular drive?

If possible, I'd like to create a new drive on the HD for personal data storage. That's it.

Hi Tony,

On a drive with a single partition hosting the OS, the amount of space that you can carve off it can vary. Did you run Disk Cleanup and Defragmenter first? You can sometimes get a few more GB if you do that. However, 50-50 looks fairly reasonable. You can change the ratio if you want, but you can't shrink the partition any further than what Disk Management permits, so I would leave this as it is.

You can then repeat the process on your other partition (the one you created from your original). Again, run Disk Cleanup and Defragmenter on this partition to maximise the potential new partition space. Remember, you can always reduce the size of a new partition to be smaller than that suggested by Disk Management but you cannot make it larger.

G'Day Dwarf, and thanks for your response.

However, you're dealing with 'as thick as two Doncaster bricks' here, as I still can't get my head around this. For starters, I don't even know which of the two Hard Disk Drives is the host of my Operating System, but I'm guessing that it is the HD (D:) Drive.

My current Partition details are here for your info;



First of all tho', in reply to some of your points;

• Through my system setup, in Properties, both of the Hard Disk Drives (C: and D:) are automatically scheduled for weekly defragmentation.
• As you can see, I have plenty of free space on both Drives, so that is not an issue or of concern.

For the purposes of this exercise, what I would like to do is use some of the free space available on the HD (D:) Drive Partition, to create a new internal Hard Disk [which I will name as (K:) Drive]. I'm thinking in terms of using about 40% of the total volume....say 55000MB, to allocate to the newly created Partition and internal HDD.

This will all depend of course, on whether or not you would recommend or sanction using the (D;) Drive Partition free space in the first place. If I cannot use it, or you recommend that I leave well alone, then I will file the idea under three thick Doncaster bricks.

If I am able to do it, then I will be using Brinks Tutorial to do the business [refer my first post in this thread], as his guide is much clearer and easier to follow than the procedures given in Windows Vista - Help and Support.

Cheers Mate.

Hi Tony,

There will be no problem in you partitioning D to give you another drive. Whether or not you can carve off a partition of the size you were thinking about, I cannot say - this depends on what Disk Management says is available. As I said previously, to maximise this space, run Disk Cleanup and Defragmenter on D prior to partitioning it.

This will not affect your OS as this is on C.

Thanks Dwarf,

I've just lifted three thick Doncaster bricks from off of my head....well that was where the idea did originate.

So now it's off to Brink's Tutorial for a thorough read, after I light up a couple of joss-sticks!

Thanks also for clarifying the location of my OS as well. Another system function bit learned.

Will post the outcome when done.

You're welcome, Tony.

Dwarf Mate....You're a legend!!

My sincere thanks for all your patience, understanding and valuable advice. Isn't this just so,....so,....partitioned?:D



I am absolutely rapt. Those joss-sticks are sure powerful stuff, and a big "TICK" can now be placed to the start of this thread.

Kudos to Shawn too for a very concise, clear and easily followed Tutorial on this subject.

.........now for a good, strong black plunger coffee, with just a wee dash of Drambuie

Marked for you, Tony. Just a simple question: What do you call a wee dash?

:huh:Aaaaaaaah!....and simply put - several things, actually;

• a pit, or comfort stop.
• Master or Miss dash.
• "Dot" [n.,fem.,sing], or "Dotty", [adj., neurological condition].
• The 3Ps - Pointing Percy at Porcelain.
• in snow - a yellow line.
• for aged humans - a relief valve.
• for me - a frantic and anxious chance to renew an old acquaintance.

and finally,

• Aaaaaaaaaaaaarrggghhhh!

G'Day Dwarf,.......and it didn't, however,

....after the success of creating the new internal Hard Disk Drive, there just had to be something to initiate that "...one gigantic topple backwards for sassofalco" !

Simmering hot with confidence first thing today, I attempted to do an incremental backup of my Files, as I usually do, to my WD 120GB external drive, via Start>Control Panel [Classic View]>Backup and Restore Center>Backup Files>Backup Files Button, etc.

The Backup started normally, but a few minutes later as it progressed through scanning Shadow Files, the backup came to an abrupt halt, signified by that nasty "dang" sound. This window appeared on screen;



So off I went to see Mr. Google with my Error 0x8000FFFF in hand, but after more than an hour of searching, I could find nothing that would even remotely help me.

I ran the incremental Backup procedure again, and again was able to reproduce the same Error.

I then focused in on the use of the word 'catastrophic', and figured that since it could refer to a major modification within my system, then it would seem logical that in creating the new internal Hard Disk Drive [Partition], I had generated the source for the Error message.

I figured that since the new Partition had drastically modified the state of the Hard Disk, then it followed that an incremental Backup would not, and could not be recognised by the modified system. The incremental backup command was therefore invalid.

With that in mind, I then deduced that a solution could be possibily be found by completing a Full and New Backup of my Files. And the result? Well, you can see for yourself;



I suspect that the Error Message 0x8000FFFF will always present in any combined situation where a Hard Disk Drive [Partition] is modified to any degree AND a post-modification attempt is made to do an Incremental Backup of Files.

If my suspicions are correct, then it may help end Users in future, if a warning about the nature of this Error message, could also be included within the appropriate Tutorial. Say something along the lines of;

WARNING - Post-modification Backups.
If you attempt to do an incremental Backup of your Files after changing the configuration of your Hard Disk, you may receive an Error message 0x8000FFFF.
In that case, complete a Full and New Backup of your Files, and when finished, delete the previous [earlier] Backup Folder from your system.


That's it. Toodle-pip.
