Deleting an HD partition of free space?

So I tried to partition my hard drive, turning it into two partitions, of which one is free space only. It didn't quite work out as I wanted it to and now I can't seem to revert it, since the "-"-button is greyed out. Can anybody help me?

You cannot remove something that is not there! Can you tell what didn't work out as you wanted.
You can Resize your Macintosh HD. select it and by clicking the bottom left option, drag it down

Adding partition in free space on internal drive

So, when I bought my 20" Intel iMac, I immediately repartitioned the drive, and created one 200GB main partition for OSX and left ~32GB of free space for a future WinXP partition (which as of today became useful .
However, I cannot find any way to add a partition in the free space without trying some commercial tool (like iPartition). Disk Utility only has the option to repartition -- in OSX it won't let me because it's the system drive, and from the install CD it wants to nuke my whole drive to repartition, even though I don't need to touch the OSX partition at all. I've also dug through diskutil, pdisk, and fdisk, but none of those have an option to add a partition.
It seems totally stupid that I can't just create a partition in free space without killing the whole disk. I have 80GB of stuff on this drive I can't easily backup.
Any ideas???
Mac OS X (10.4.5)

The second partition is not for backups... it's for a FAT filesystem for installing Windows so that I can run my research software and play games at native speed.
Installing XP does not involve any firmware changes at all. The EFI bootloader is a blessed file that sits on the HFS partition, and the boot sector of the XP install CD is modified to talk to the custom EFI bootloader.
I actuallly did solve the problem through some brute force after my post. There is a command-line utility built into OSX now called 'gpt' which can edit GUID Partition Tables as used on Intel Macs. I booted off my OSX install CD, went to a terminal, unmounted /dev/disk0, added the new partition (gpt luckily does have an option for adding and removing partition entries without repartitioning the whole disk... Apple really needs to update Disk Utility if you ask me -- this is a common and simple task usually), then rebooted. It all worked fine!

Live Partition Resize not working... And can't add partition to free space

Hello everyone. I have a problem that I'm trying to sort out.
I have a 500GB WD MyBook external FireWire HD. I had it partitioned into two partitions. One was a 112 GB that I used to create backup images of the 120 GB internal drive of my PB G4 (really 111.66 GB). The other I used for other files.
Now, I decided that I wanted to start using the Backup partition for Time Machine, but in order to maintain a longer history, I wanted to increase the partition size. I figured this would be a snap with the new capabilities of Disk Utility. Unfortunately, it was not. While it is true that my pocket FireWire drive behaves exactly how I'd expect it to in DU, the 500 GB WD drive does not. I can't do anything to the partitions, in a live manner (the options, + and - buttons are all grayed out, and there is no indication of volume fill status).
In a fit of frustration, I tried deleting the backup partition. That worked, but now I just have 112 GB of free space, and I still can't do anything with it. I can't even add a 112 GB partition back into this free space.
Does anyone have any ideas about what is going on here, and what I can do to get things working properly?

Adding a new partition in free space wipes all others?

geez, I hate writing a question when I think I've already found the answer!!
But in this case, the answer's so baad, I thought I'd run it by you all before I hit "desperation" mode! Here goes...
I've got a USB 1TB external that I back up on to. It's in 4 partitions (audio, video, system, archives). The 4 partions are using about 750 Gb total, with 250 Gb free. I wanted to resize the "system" partition, as it was getting pretty full. I found some instructions about; (1.) creating a new, fifth, empty partition out of that 250Gb free space then (2.) "merging" the new partition and the system partition, resulting in a single larger partion for system backups. All other partitions *should* have been left untouched.
I was a bit wary of it all, but Disk Utility's Help says, "You may be able to create multiple partitions on your disk without losing any data" and then goes on to tell me how to, using the + sign, create a new partition out of the 250Gb of free space.
I followed the instructions to the letter but, after "Applying", it did create the new fifth partition, *BUT IT WIPED ALL OF THE DATA OFF OF THE OTHER FOUR PARTITIONS!!*
I'm in major panic mode, did a bit of searching and, on Indiana Univ. help page, found:
"Warning: ...when changing the partition scheme in Mac OS X 10.5 and later, partitioning your hard drive with Disk Utility erases all the information on the drive."
As I see it, a direct conflict to what Apple claims in Disk Utility's Help.
So, I'm about to pull out and upgrade my data recovery programs - - will just try and get the pix and tunes back, I guess.
But if anyone has any idea how I can "undo" what's been done, it sure would help!!
many thanks in advance,
b myers

I'm not sure what you did exactly, but having done it you cannot undo it. You may yet be able to recover files from the drive using recovery software:
Basics of File Recovery
Files in Trash
If you simply put files in the Trash you can restore them by opening the Trash (left-click on the Trash icon) and drag the files from the Trash to your Desktop or other desired location. OS X also provides a short-cut to undo the last item moved to the Trash -press COMMAND-Z.
If you empty the Trash the files are gone. If a program does an immediate delete rather than moving files to the Trash, then the files are gone. Recovery is possible but you must not allow any additional writes to the hard drive - shut it down. When files are deleted only the directory entries, not the files themselves, is modified. The space occupied by the files has been returned to the system as available for storage, but the files are still on the drive. Writing to the drive will then eventually overwrite the space once occupied by the deleted files in which case the files are lost permanently. Also if you save a file over an existing file of the same name, then the old file is overwritten and cannot be recovered.
General File Recovery
If you stop using the drive it's possible to recover deleted files that have not been overwritten by using recovery software such as Data Rescue II, File Salvage or TechTool Pro. Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive. Two free alternatives are Disk Drill and TestDisk. Look for them and demos at MacUpdate or CNET Downloads.
The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.
Also visit The XLab FAQs and read the FAQ on Data Recovery.
For future reference:
To resize the drive do the following:
1. Open Disk Utility and select the drive entry (mfgr.'s ID and size) from the left side list.
2. Click on the Partition tab in the DU main window. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed. (Note: You can only make a partition smaller in order to create new free space.)
4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
You should now have a new volume on the drive.

Adding partition to free space on external that contains RAID 0 array

Hello.
I have a Lacie 2BIG 6TB Thunderbolt drive. This was partitioned into a 5TB RAID-0 array, with some smaller partitions in the rest of the available space for other media and backups.
I tried to delete the other partitions to consolidate whatever space was used by these for other media. Disk Utility let me remove these partitions, but when I try to recreate anything in the free space now available, Disk Utility states that it will also erase the partition that is used as a slice of the RAID array.
I do not have the space to move everything off the array to completely re-partition the disk, and am looking for a solution to re-partition only this free space on the pair of physical drives.
Can anyone offer any advice on how I might accomplish this? I have tried to attach images of what Disk Utility shows when I attempt what what I want to do.
I have tried iPartition, and would like to try Drive Genius, but I'm not sure that this will help the situation.
Thanks a lot.

Just a quick confirmation that I have still been unable to resolve this after a few more attempts.
Anyone out there know more about this than I do?
Thanks.

Unable to create partition from free space on hard drive

I have a segment of free space on my Macbook Air's hard drive. It was formerly a Bootcamp partition.
When I try to create a new partition from this free space in Disk Utility, it prompts me to start creating the partition, but nothing happens after that. I can leave the machine alone for hours, and nothing has occurred. Disk Utility thinks it's working though, since it prompts me to cancel the process when exiting the app.
Any thoughts on how to fix this? Thanks!

Freeing Up Space on The Hard Drive
1. See Lion/Mountain Lion/Mavericks' Storage Display.
2. You can remove data from your Home folder except for the /Home/Library/ folder.
3. Visit The XLab FAQs and read the FAQ on freeing up space on your hard drive.
4. Also see Freeing space on your Mac OS X startup disk.
5. See Where did my Disk Space go?.
6. See The Storage Display.
You must Empty the Trash in order to recover the space they occupied on the hard drive.
You should consider replacing the drive with a larger one. Check out OWC for drives, tutorials, and toolkits.
Try using OmniDiskSweeper 1.8 or GrandPerspective to search your drive for large files and where they are located.

Deleteing files doesnt increase the free space on my harddisc

My hard disc has only 766 MB free space. When I´m deleteing files I don´t get more free space.
I have deleted over 1 GB today by putting files into the trash can and then empyting it, but it is still only the 766 MBs of free space.
Help?

I dont understand the word "sparse". What is this file? Can i delete it?
This file contains your encrypted home folder. As long as you have FileVault turned on, don't delete it.
I have FileVault enabled but when I try to disable it it says that there is not enough free disk space.

Deleted files wont give me free space

i created two projects on my laptop, then exported them back to dv and dragged the projects into my trash bin. I then emptied my trash, awaiting the free space i had missed so greatly( the projects took up about 20 GB each), but after the files were deleted, which took about a second. i did not get the free space back, does anyone know what happened or could someone point me to another forum where this questin could be answered.

Type Media in finder you may find those deleted files still have a connection there. Careful you don't delete the wrong ones because they're gone. anoka114

Merging the main partition with free space: is this possible?

Hey all!
My hard drive currently contains two partitions: 200 GB for the Tiger and 30 GB of free space I left when I wasn't yet sure if I will not want to install Linux on it. Now I am sure I won't and I'd like to merge these 30 GB back onto the first partition. Is this possible?
$ diskutil resizeVolume disk0s2 limits
Shows 200 GB is max size for the first partition. Guess then that this won't work:
$ diskutil resizeVolume disk0s2 230G
Any suggestions would be very appreciated!
Artemiy.

Although there are utilities available to repartition a hard drive without erasing all data on the drive, I wouldn't trust them and since you need to create or update your backup beforehand anyway to be on the safe side, do so and then reformat the hard drive with the Tiger install package that shipped with your Mac to a single partition. This will erase the hard drive completely first and then re-install OS X and all included software along with any 3rd party software and then re-store your data from the backup.
Or with a backup utility that provides for it, create a bootable clone backup of your 200GB partition saved to an external drive. Reformat the hard drive and then restore everything completely from the bootable clone backup.
When reformatting, be sure to select HFS+ (or extended) with Journaling enabled.

Delete AUD$ table do not free space

Hi,
We have an Oracle 10g database (10.2.0.4) with the Oracle auditing feature on.
Our problem is that I delete on regular basis the AUD$ rows, but the system do not free the space on the tablespace. The system free the space only after a truncate.
The actual situation is:
SQL> select segment_name,bytes/1024/1024 as Mb from dba_segments where bytes/1024/1024 > 1000 and TABLESPACE_NAME='SYSTEM';
SEGMENT_NAME MB
AUD$ 10161
SQL> select count(*) from sys.aud$;
COUNT(*)
+1073+
Someone can help me with this!?
The delete of the table is done with a simple script:
select count(*) from sys.aud$;
delete from sys.aud$ where NTIMESTAMP# < sysdate -(1/24*6);
select count(*) from sys.aud$;
commit;
exit;
Thanks

Do you know if that is a know bug!?No it is not a bug.
Why are you concerned about the space being released? If it were you'd just have to re-aquire it as new rows are added to the table.
As rows are added, when an extent is filled a new extent is allocated. If rows are deleted those extents remain allocated to the table and are re-used as needed. The aud$ table is a perfect example of a table which most definately will need to reuse that space, so it it a total waste of effor to try to reclaim it.Hi, that is the real point, it seems that the table don't use the allocated space.
It constantly grows and reclaim new space. That is the real problem for me.You haven't demonstrated that. You only showed us a one-time snapshot of the space used and the row count.
You need to track this over several days / iterations of deleting rows. Show us that over a period of time the row count is fairly stable and yet the space used continues to increase.
If, today the rowcount is 'x' and the space allocated (measured in blocks or extents) is 'y', and you delete a bunch (or even all) rows, space allocated should remain 'y'. Then tomorrow, you should have near 'x' rows again (assuming a fairly level amount of audited activity). And space allocated should still be 'y' .. maybe allowing for a slight increase in 'x' triggering one more extent. But if you are regularly pruning the row count, the number of extents should stabilize. If not, then you do have an issue, but I haven't yet seen proof of that happening.
>
>>
Can this create problems since AUD$ is a system table!?No, but you don't want a very active table like that in your SYSTEM tablespace. Oracle puts it there by default, but there have been well known procedures on the net for YEARS on how to move it to another TS. Thanks
With 11g, they've even introduced the dbms_audit_management package to help with these tasks.I know, I hope the my customer will authorize the upgrade soon.
Thanks for your suggestion to upgrade sybrand_b, but as you can understand, sometime the upgrade are not possible until the software vendor will authorize that, so, we need to work on version 10.2.0.4 for some other months.
Regards
Nunzio
P.S. I think that there are problems, after the move of the table to a different tablespace, and the move back to SYSTEM, the used space was around 2Gb, but I was not able to resize the datafile. Don't move it back. Get it out of SYSTEM and leave it there.I think that I'll do this, at least to not risk the corruption of the system tablespace.
Thanks again for your answers.

Nunzio

HT3529 how do i delete old message conversations to free space

I'm running out of space on my iphone 4 and, according to settings/general/usage, my old text messages take up 4+ GB of space. How can I set it up to only save texts for the last, say, six months?

Basically, all you need to do is swipe the conversation to the right - left and press the red delete square. Unfortunately this will delete even the most recent text with this person, but that is all that apple offers built in the operating system. Additionally, you can press the edit button in the top left corner and press the minus next to the contacts to delete the conversation.

Deleted Data, no increase in free space......

We have deleted in excess of 1.2M rows of data from 3 tables within the database, but have seen no real increase in the amount of freespace in the datafiles, what else do i need to do or missing,,,,
TY, newbie, WAR.

Hi,
Oracle datafiles cannot release the extents acquired automatically when data is deleted. Any new data added is always appended by acquiring new extents. Truncation is the only way of reducing the datafile size.However, if all data cannot be deleted, then truncation cannot be used. An idea would be to delete the reqd number of records, then use export utility to take a dump of the remaining data, then truncate the table, and then import the data back into the table. (during import, you should specify the option 'Ignore error due to object existence...' etc as 'yes', so that the data will be appended to the empty table.)

How to delete "Free Space" Partition?

I partitioned my MacBook Pro into 2 volumes so I could dual boot Mavericks and Yosemite Developer Preview. After testing Yosemite, I found out that it was stable enough to run on my main partition. I installed it on my main partition replacing Mavericks and deleted the second partition which included Yosemite. While deleting, somehow I was left with an empty partition called "Free Space" which I cannot delete.
I am pretty sure the problem isn't related to Yosemite being a developer preview as it could've happened under an previous stable OS. How can I merge my "Free Space" partition with Macintosh HD?
MacBook Pro with Retina display 13-inch Late 2013
2.8GHz Intel Core i7
16GB RAM
Intel Iris graphics
512GB SSD
OS X Yosemite Developer Preview 2

If you select the top partition, does ////// lines appear in the bottom right hand corner? If so try selecting them and dragging downward. Boot into the Recovery Volume (command - R) during a restart and try it there.

Cannot Partition Free Space on my external drive

Hey Everyone,
I am trying to partition the free space on my external drive. Used to have 3 partitions on my drive 2 HFS+ and one FAT (originally created by disk utility). I upgraded to leopard and thought i would give time machine a shot. so i erased two of my smaller partitions (the FAT and small HFS+) and put all the data on the 3rd (HFS+).
The drive now has one partition at 350GB (Lacie Disk) and 100GB at "Free Space".
I have tried Disk Utility, Micromat Disk Studio and Drive Genius 2 and none of them will allow me to repartition the free space on my external drive.
I am rather confused as to why i am "not allowed" to do this. I can't delete the 350GB of stuff since it IS my backup and my drive on my mac is only 160GB.
Any suggestions to work around this or as to why i can't repartion an external drive.
Thanks
R

selct the whole drive (the model, not the partition name) and disk utility and look at the bottom on the right. what does it say on the line Partition Map Scheme?
If it says Master Boot Record you can't repartition the drive without erasing everything. if it says Apple partition Map or GUID partition table you should be able to add a partition in place of free space by clicking on the + button in the partition tab.

"Free Space" Partition

I deleted my windows 7 partition and it left a partition called "Free Space" that i am unable to delete or resize. I have booted from cd, and i tried to delete the partition and resize my MAC partition. I was unable to make any changes to the "Free Space" partition. I have attempted most of the mainstream fixes for partition problems. I would like to go about fixing this problem without erasing any data. Any help would be greatly appreciated. Thank you in advance.

The free space entry is just that; space not used by any existing partition. If the Mac partition is above it in the list, drag the slider down as far as it will go. If the Mac partition is below it in the list, create a new Mac partition, clone the old one to it if it's large enough, boot from it, delete the old partition, and see above.
