How to reclaim hdd space after compacting VHD in hyper-v

I have a virtual machine installed on Windows Server 2008 using Hyper-V. The VM is using Windows 7 as its OS. I had originally set the size of the dynamic disk to 40 GB but soon learned that wasn't large enough and expanded it to 110 GB.
Now I an no longer running the VM and need to reclaim some of that space while keeping the VM intact. I have run the compacting wizard, and it says the disk is now 24 GB with a maximum size of 110 GB. Yet all of that space is still allocated
for the VM's use. How do I reclaim the empty space?
I have tried to go into the VM and shrink the current volume, but it says I don't have enough space to do so.
I appreciate any suggesions as I really need to reclaim some of that hdd space.
Thanks!

Hi InScribeKBriggs,
>> I have run the compacting wizard, and it says the disk is now 24 GB with a maximum size of 110 GB.
Please ensure that you are using correct wizard , only "Inspect disk..." will show the information
“the disk is now 24 GB with a maximum size of 110 GB” .
Please use "Edit disk..." , before you do this I would suggest you to execute
disk defrag in windows7 VM first then shutdown it then execute "compact" in "edit disk..." wizard.
Byt the way , it is a dynamic disk and the current size is 24GB means
the size on physical disk is 24GB , maximum size means it can grow up to 110GB this can not be decrease .
Also please refer to following link to compact the dynamic VHD :

How to reclaim the space after delete

Hi All,
Today we deleted large number of rows from one table, but we didn't get free space after that. So for testing purpose, I have created one test tablespace with 5mb size .Created a table and inserted n number of rows in that table and made the tablespace full.I checked in dba_segments(5mb) and dba_free_space tables.It shows perfectly.After that I deleted all the records and try to create a simple table,but it returns (ORA-01658: unable to create INITIAL extent for segment).I read some time back in tom's forum that delete willn't reclaim the space ,instead it will go to freelist of table..Is there any way to reclaim the space?(after delete)
and also I used to see the tablesize by using dba_segments table.but now it shows 5mb of size for the empty table.Is there any query to get the exact table size?Please help me to understand the concept.
Thanks,Jvel

Thanks,JvelDELETE simply deletes the specified rows. The blocks/extetents that were allocated to hold those rows remain allocated. The theory is that if the table once needed sufficient blocks/extents to hold 'x' rows, it may need so again at some time in the future. Allocating and de-allocating extents is a pretty expensive operation, so oracle is not going to waste time and resources constantly doing that just because you delete rows, which is a perfectly normal DML operation. Unless you don't expect that table to grow again, I'd not waste my time trying to reclaim the space.

How many free disk space after install OS X lion (10.7) ?

Hi,
I would like to know that how many free disk space after install OS X lion (10.7) on MBA i5.
Many Thanks,
Eric

I want to buy MBA i5, I would like to free disk space of MBA 13" i5, Could anyone tell it to me? Thanks
As you're buing a new MacBook Air, it will come pre-installed with Lion. The actual installation will be somewhat larger than a "clean" Lion install as it will come with iLife preinstalled. Obviously, with an Air's limited storage space, you want to be sure that you have enough room for any applications and data that you'll want to keep on the SSD as well. It is fairly easy to upgrade the SSD on an Air:

The amount of RAM you have installed is probably more important. Fortunately, the newest 13" MacBook Airs all come with 4GB standard now.

Lost all my HDD space after cancelling partition!

Short Story...Ive lost all my HDD space after cancelling partition, i had 1TB now i only have 13gb
Long story...I installed parraeles desktop 8, went to install windows 7, it said i only had 60gb free, went to disk utility to try and partition to 150gb but only allowed me to partition 50:50 for unknown reason, i began the partition and then cancelled it as i wanted to try and only allow 150gb for windows 7, now it does not show partition at all, and says i only have 13gb free!!!
PLEASE HELP ASAP!!!!!!
Running OXs 10.8.2

Do you have a Time Machine backup of your system, if not make one. Then go back into disk utility and delete the partition you just made. To install Windows 7 via Parallels Desktop 8 you don't need to partition your hard drive the program takes care of the entire install.

How to reclaim spare space back at the end of my clips on the time line

When I have edited stuff on the time line I find that through moving clips around that I have an empty space after my collection of clips that I have arranged. How do I reclaim that empty space back so that where my clips end so does the time line.
I have tried saving the project and reopening it but this does not seem to do anything as I still have the space left.
Any help would be gratefully received Thanx ahead of time.

Control click on the empty space and, on the drop down menu, click on Convert Empty Space to Clip. Then, delete the clip you just created.
If the empty space is at the end of your movie, you can do the same as above. But, if your playhead still continues moving past the end of the movie, then expand your time line as wide as possible and check down your time line for little bits of clips left over from editing, and delete those. Any audio that extends past your video clips at the end of the movie should be trimmed back as well, even if you have muted them.

What i need is,
Q1 . Ways to reclaim the purged space from the table1.
Q2. How to shrink the table/ tablespace? Is it possible to do it online without impacting the users/business?
Q3. How to shrink/maintain LOBSEGMENTS space, that is , how to control the size or reclaim the space from LOBSEGMENT after the daily purge on the Table1?
Quick help is much appreciated and thank you in advance.

Reclaim disk space after delete an index

Hi ,
I have deleted unused indexes from a history table to reclaim the disk space was allocated for these indexes , yet the size on the disk is the same , any steps I can follow to achieve this would be greatly appreciated..
indexes size is 70 GB
table size is 45 GB , # of rows is above 200 Million
Thanks in advance

in order to reclaim space after your big delete. Don't shrink your data files unless you have no other choice.
The space will automatically go back to SQL server. You don't have to do anything.
The database size will be the same plus the growth of your log file due to logging the transactions. However, internally, SQL server knows that it still has that space to play with.
Other wise you can go for update the statistics and rebuild indexes . but I think it would be the part of your normal weekend nightly maintenance plan

Lost HDD space after reinstall of OS X

I recently purchased a Mac Mini (Mid 2011) used. The previous owner failed to restore to factory settings. Being a good neighbor, I looked for a way to restore and rid the Mac of their info. I pressed the (command + R) shortcut and then it had a world on screen. It checked the hard drive and components, I assume from reading, then went to a small menu. I read that I would use disc utility and erase option. I did. Set the correct formatting. Then I go back to the small menu. I didn't have wifi connected so next it prompted me to connect. When I clicked off the menu, it disappeared. I could not see it again nor could I see wifi option. I read it was at the top right so I click, click, click, and viola wifi option. Obvious at this point the screen is not all showing. I'm on a Sony Bravia 32". Now with wifi connected, I began searching for where the menu may have hidden. No luck. I was forced to shut off and try again. (Command + R) again. Small menu is back after the world pops up and checks everything again. I click install Lion and it checks with Apple and asks what HDD. I originally had 500.11 GB. I checked it via the guest account prior to my trying this. It may have also been seen during the process mentioned. Then it gives an HDD with only 499.87 GB. I think OK maybe it's an updated larger version of Lion. So I proceed. Half way through a 7 hour stint, my wifi signal gets knocked out. It prompts to reconnect and then start again. The problem after that is the status bar is all blue and no download time left anymore which one would think its indicating its finished. I knew better than that so I left it for what I think was still maybe downloading. Another 7 hours later. It is still running. I make the decision to abort and try again. This time taking same steps, but with a 12' Ethernet cable. No more disconnects. Now it goes through same process then for hard drive selection it says 498.22 GB. So obviously with no other choice, I select it. Now for the questions.
1. What happened to HDD space?
2. Can it be recovered? If so, please do tell! Without $100 in additional software.
3. Did I seemingly succeed in removing previous owners info?
4. Why does downloading via Ethernet have the same speed as wifi?
5. When I complete reinstall can I register this product with Apple?
6. Will making a USB drive allow the same small menu and options for restoration of the Mac?

First off, you should run the Safari 4 beta uninstaller that came with Safari 4.
Secondly, if Safari 3.2.1 doesn't work, it probably is because some network application you previously installed hasn't been tested with it. Did you install any cell phone or PDA syncing software recently? The Hotsync typically is a plugin for cell phone or PDA syncing software.

How do I remove space after paragraph?

Does Robohelp have the "Remove Space after paragraph" button for reducing the space between lines, like the one in Word?

In HTML the space after is controlled by the style in your CSS file. You need to edit the style in the Style Editor.

Pages for iPad - how do I create space after a paragraph?

All I want is one line space after each numbered paragraph in a document.
When I press return twice, the numbering restarts!
Help.
Thanks.

On the iPad, documents are saved directly in the app in which they are created. Your Pages documents are saved automatically as you work on them. If you quit working on the document right now, your progress is saved on that file. No need to save like you would on a computer.
When you close Pages and come back to it later - all of your documents will be listed in thumbnail view on the first screen. Tap on the document that you want to work on and it will open.
There is a help feature within the app. Tap on the wrench icon in the upper right corner and select Help from the resulting menu.

Mysterious usage of my external HDD space after last backup on TM?

Recently, after some problems with TM giving me a pop up error, I turned off TM and used my WD MyBook as a normal external and have just been copying files onto it. Last night, I figured it has been a bit too long since I last backed-up my mac's HD (I backed up right before I upgraded to ML in the beginning of August). It took well over an hour for it to just prepare the backup, then took almost all night to backup 100GB worth of data (I downloaded a few games and I purchased a few TV series). Before the backup, i checked the "Get Info" option of my external and saw that it said I had about 600GB of my 1TB left for space, but then when I started the backup, it went down to 70GB left!!! My internal HDD is only 250GB, so I dont see how 600GB could be used up just like that... with all the files (pictures, videos, shows, and games) that I manually put into my external HDD, i use up only about 300-400GB. Even if I used up ALL of the space on my internal and backed up everything, it still doesnt add up to the 900GB that have been mysteriously used up. Any clue where all of this data was used up? should i delete my old backups from older versions of my mac's OS and just make the most recent back-up what I have on my mac now? Any help would be appreciated!! I feel as if TM did something wrong when i backed up my data after 2 months

By going into the options you gave me, it said that the size of the backup should still be 211GB, which still doesnt make up for the good 300 GB discrepancy. Could it be that it is making multiple copies of my internal due to the fact that i updated my OS?

How to give two spaces after new order in alv

hi
my issue is after every new order number they need two blank spaces, i know the procedure of giving new page for every new order but they need only two blank lines. (This is in ALV List format).
second thing is how to give footer
thanks

hi
use this variant of appendf for inserting blank lines
Append INITIAL LINE TO ITAB.
Effect
Appends a new line to the end of the internal table itab. You can only use this variant with index tables (standard or sorted table).
If you specify wa TO , the new line is taken from the contents of the explicitly specified work area wa.
If you use INITIAL LINE TO, a line filled with the correct initial value for the type is added.
If the part before itab is omitted, the new line is taken from the header line of the internal table itab.
If you use the ASSIGNING <fs> addition, the field symbol, <wa>, points to the line you have just appended. If you use the REFERENCE INTO ref addition, the data reference, dref, is filled with the reference of the line you have just appended.
If the target table itab is a SORTED TABLE, it must be sorted correctly after the append, otherwise a runtime error results.
After the statement has been executed, the system field SY-TABIX is filled with the index of the last line in the table.
Cheers

Reclaim Disk Space After Deleting Versions.

We've recently went through a few large Document Libraries using Power-Shell and deleted tens of thousands of versions of files we didn't need the version history for.
Unfortunately the DB size has not gotten any smaller. I went in to try and shrink the DB however there is very little available space to reclaim.
Is there something else that needs to be done after versions are deleted to fully release the drive space on our SQL box?

Measuring the MDF/LDF isn't going to be a good calculation. For one, you have padding done by SQL Server itself, then you have index space and other metadata storage, and of course you have all of the information that is associated with the BLOB anyhow.
But with 3 versions of the document, again only the differences are stored, so it wouldn't be 600KB * 3 in that case.
http://blogs.technet.com/b/wbaer/archive/2012/11/12/introduction-to-shredded-storage-in-sharepoint-2013.aspx
Also, why are you wanting to shrink the database? Shrinking destroys the indices and generally degrades performance (e.g. if you encounter another data file expansion).

How to reclaim "free space" on TM drive?

I had 2 partitions on my external drive. I've deleted one of them as it is no longer need. Is there a way I can tell my TM partition to reclaim this new "free space" without having to erase the entire disk?
Thanks

Dryvlyne wrote:
That's exactly what I did to erase the partition, however, that partition is/was positioned first on the drive, above the TM partition. Hopefully that makes sense, but that's where I'm stuck at.
Thanks
in that case you can not absorb it into the other partition without reformatting the whole drive (that will wipe all the data off it). At least you can not do it with disk utility. Using disk utility you can only adjust the size of a partition by dragging its lower right end up or down.
