Advice on removing partitions on Ext HD

I'm using a 5TB external drive. I've partitioned it into 3 and have data saved on all 3 partitions. I now want to remove partitions 1 & 3 and allocate that space to the middle partition (2) without losing any of the data on partition 2. I am unclear as to whether I can do that using Disk Utility. Any advice???

So, essentially you want to change it back to a single partition disk?
I would recommend you copy the data you want to keep to another location or drive then re-format your 5TB external drive to a single partition volume.
You can then copy it back once the format is complete.
Any other method would be messy or would require 3rd party software. A re-format is by far the easiest and quickest solution.

Partitioning an ext. HD for use with Time Machine HFS+/FAT32

Hi, I hope that this question is not already answered somewhere - I did a couple of searches but couldn't find the answers I need.
I'm setting up an external LaCie 500GB HD (USB 2.0) for a friend, in order to use it for Time Machine backups (one partition) and as a non-backuped "data dump" (music / films etc.).
My plan is the following: Partition the ext. HD into a 200 GB HFS+ Journaled partition for use with Time Machine, and a 300 GB FAT32 partition for data (FAT32 to ensure the interoperability with PCs).
I have a couple of questions (apart from if you think the proposed setup is good in general):
1. The Time Machine partition would be used to back up a MacBook with a 120GB HD - in your opinion, is 200GB too much/enough/too less space?
2. In general, does Time Machine work with partitions on ext. HDs as seen in the setup I propose? (or should I use a drive with only one partition?)
3. are there any possible problems I might run into when partitioning a drive into two different file systems as HFS+ and FAT32?
4. Is it OK to use the Leopard Disk Utility for this or should I use another application?
thanks a lot for your answers!

Hi,
Could you please share the answers you found?
I'm going through a very similar situation...
Thanks!

How do I remove partitions "PV2" and "Boot Camp"?

I tried installing Windows 7 in Boot Camp and lost power during install. I want to completely start over but have partitions "PV2" and "Boot Camp" that I can't seem to remove. I have tried to remove partitions in Disk Utility but everything is grayed out. Boot Camp Assistant says "The disk appears to have been partitioned by another utility and can't be removed."

When I boot to recovery (Command+R) it gives me four options: Restore with Time Machine Backup, Reinstall OS X, Get Help Online, and Disk Utility. I am assuming I should erase the drives usings Disk Utility. I am able to select the PV2 and Boot Camp but when I select the "partition" tab the +/- buttons on the bottom is grayed out. I am not sure how exactly to "erase the entire drive." If you couldn't tell, I am a novice imac owner. I did make a backup using Time Machine earlier today.

Please advice about table partitioning

Hi.
I need some advice on table partitioning. Here is the problem : My application procesess 7 types of documents (all like invoices). I have created master/detail tables for each type of document. But the are no big difrences between documents, so I was planing to move all of this document types to one master and one detail table and use table partitioning based od document type. This would to simplifay my programming very much... but I am not sure how will this effect on application performance ??? We process a large number of documents (over 300 a day).
So what do you think ?

1) If you are using the standard edition, partitioning is not an option. Partitioning is an extra-cost licensing option that is only available to enterprise edition customers.
2) I am having a bit of difficulty reconciling the numbers you are providing with your descriptions. An application that inserts 5 MB of data a day and adds fewer than 2 million rows per year is a pretty small database, particularly to consider partitioning for. 50 active users doesn't seem terribly large. It is far from obvious to me that separate schemas by year provides any sort of benefit overall. OLTP operations should be able to use appropriate indexes to avoid all the read-only data. And a single schema with a single set of tables minimizes the number of hard parses you have to do, the number of queries that have to be rewritten every year to go after new schemas of data, etc

Bootcamp won't let me remove partition without 10gb free space

I want to free up my mac by deleting the windows partition but boot camp won't let me because I don't have enough free space UGH! I can't get to the selection in boot camp that allows you to check "remove partition" because I keep getting a pop up window telling me I don't have 10 gb free space and therefore can't continue. This is a real glitch. They shouldn't have the remove partition feature behind this minimum requirement. Any suggestions around this? I've already deleted everything I can but don't want to keep trying to find more if someone has a better idea. Thanks.

Removing partition

Have Mac Pro Quad 2.66 with 4 HD's and 5GB RAM.
HD#1= 250GB OEM; HD #2=500GB with 2 equal partitions, 232 GB each (2A & 2B); HD#3=750GB; HD#4=750GB -used for Time Machine.
OEM HD#1 has Tiger 10.4OS+data and applications from previous iMac.
Installed 10.5 on first partition of #2 (2A). Now however I'd like to remove the partition on #2 as I currently only have 44GB left on first partition (out of 232). HD#2A has been backed up on HD#4 with Time machine.
Question: can I remove the partition on HD#2 without erasing OS 10.5 on HD 2A and all installed applications?
If not then I assume I can boot from 10.5 install DVD and install on HD#2 from HD#4 with data from TM. (Mac OS 10.5 Help "Recovering your entire system")
Is there an application that will let me remove partition without a fee, iPartition cost $50. Or as an alternative does OS 10.5 have a "remove partition" that destroys all data? If so I guess I can restore with Time Machine.
I'm a somewhat experience Mac user-6 years-but I'm a bit over my head on this issue(s). Any help would be appreciated.

Pull your #1 OEM and put it aside as your insurance. Or clone it to a FireWire drive.
Partitions are never perfect size. Leopard does allow for resizing to some degree. Of course you want backups. More than one hopefully.
I would think a 750GB drive would be idea for boot drive. Maybe half.
I prefer to keep the boot drive as just the OS/apps and keep data on 2nd drive.
A boot drive doesn't need to be more than 100-200GB but you also want a lot of room for burning DVDs and work, and just for performance, to never fill it beyond 50% either.
While moving things around, make sure you always still have your original boot drive and a recovery plan.
I'd get another drive for your OS. 10K Raptor ideally. Or another 750GB (it is nice to have drives of same size, make for moving things around, RAID, etc, as long as it is reliable).
You can't boot from an iMac system and you probably have the data backed up. And you could even put it on a sparse disk image on your TM volume. (I have three TM drives that I use and rotate, so if something happens I still have a backup of my backup).

Removing Partition Failed in WD External HD All The Time!

Have problem in removing partition in WD External 1 TB Hard Drive!
The Main 1 TB WD My Passport is showing Format in MS-DOS (FAT) while the two partition under it shows in Mac OS Extended (Journeled)!
I want to remove both partition and creat one portion in Mac Extended (Journeled) Format. Everytime I try to create 1 portition with Mac Extended (Journeled) Format it failed with showing " Partion Failed : couldn't unmount disk" message!
Is there anyone who is faced same issue and fix it?
Thank you in Advance

In your second image it says…
You can't resize the partitions on this disk because it uses the Master Boot Record partition scheme.
So you will have to delete both partitions & recreate them as desired, losing any data on that disk. Are you sure that you need to use a MBR partition table? Have you got backups of this data on any other disks? Backup these volumes before you begin.
MBR is generally a Windows format for booting Windows OS's. Mac OS used 'GUID partition tables' by default & will allow resizing on GUID tables but not MBR ones.
If you want to repartition the disk with a GUID partition table try this…
Select each of the volumes in the sidebar & choose 'Unmount' in Disk Utility's toolbar ('02' and 'Mac OS' should become unmounted unless some process is using files on either volume). Note: 'volumes' are the indented items below the disk in the sidebar.
In the Partition tab, edit the 'partition layout' to create 2 volumes & resize them to whatever you need, also set the format & names etc.
Click the Options button & set the partition table to use 'GUID partition table'.
When you apply that the disk will be reformatted & the entire disk will have the data removed & new file systems will be written.
If you cannot get that to work, quit all other apps reboot & retry - that may stop other apps using any files on these volumes.

Trouble Removing Partitions

Okay folks, I am trying to remove partitions from my hard drive that I made for when I installed Linux Mint on my machine last fall.
Awhile back, I uninstalled Mint per instructions, however, I have been stumped as to how to reclaim space for those partitions (about 140 GB)
I go into Disk Utility, select my Hitachi Drive, click the partitions I want to delete, and hit the minus button in Disk Utility, then click remove, btu the utility gets frozen in "preparing to remove volumes" and makes no progess from that point!
How do I fix this and get rid of these partitions so I can get that disk space back?

Get your files off and c boot off the installer disk and Disk Utility Erase with Zero and format the drive HFS+ journaled and reinstall OS X. You might as well fresh install Snow Leopard while your at it and can still get it from Apple (hurry once Lion is out your screwed!)
Next time look at using rEFIt and setting it up that way it's a EFI program, there are uninstall instructions too.

Record drive/partition "500G Ext HD Western Digital" not found!

I don't know why I'm getting this message when I open any songs I've recorded in Logic Express. It just started doing this today. Here is the message:{Record drive/partition “500G Ext HD Western Digital” not found!}
I do not get this message when I open and work on songs I've recorded in Garageband.
The 500G Ext HD is my external hard drive.
Does anyone know what this means and how I can resolve it and get back to recording music??

Does the disk appear OK on your desktop?
When exactly do you get this message? When you double-click on a Logic file on your external drive? Or when you start a new project? Is your record path set properly in Logic?
First, as you may be nearing a hard disk problem, make sure that all essential files are backed up properly.
Then, open up your Disk Utility and run 'Verify Disk' and 'Repair permissions' on your external drive. If you have a copy of Disk warrior, even better.

Remove partitions from a Hard Drive

1. Connect the drive to your computer, either internally or externally using a USB cable/enclosure.
2. Right-click Computer (This PC) > Manage > Storage > Disk Management. Identify the disk you want to delete/format and right-click the graphic of the partition to be removed, select Delete Volume and reply Yes. The partition returns to Unallocated.
Repeat this deletion for the other 2 partitions.
3. Now right-click the graphic for the unallocated space then choose New Simple Volume. Type in a meaningful Volume label name and format it (Quick format is sufficient). It is now ready for use.

Need help removing partition on macbook pro

Hello
I have a macbook pro 17" OSx 10.6.6
I have a partition that i am trying to remove. When I open up boot camp assistant and click continue then click i already have downloaded the windows support software to a cd dvd or external disk it tells me that the startup disk cannot be partitioned or restored toa single partition.
I am stumped.
Any help would be greatly appreciated.
Thanks

Have you tried to repartition the drive with Disk Utility to add a third partition or to remove the Boot Camp partition?
I would repair the hard drive to see if that helps:
Repair the Hard Drive
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

Remove partition created in reformat/reinstall for A50

So when I got my Toshiba Satellite A50, it had no partition I knew of, just a C drive with XP installed on it. But the disc that it came with for reformatting the hard drive and reinstalling XP is creating a partition!
So this is not the original installation or set up that I had.... I already have an external hard drive, I don't want a partition.
How can I remove the partition? I'm willing to completely reformat the hard drive all over again, but if so, how do I do that?
The Toshiba CD doesn't really give me a command prompt to go reformatting the hard drive myself....
The other annoying thing is that my C drive was NTFS, but the disc is creating one drive NTFS and the other FAT32... also ... what's really scary, is when the Toshiba disc loads it says "loading Windows 98".... to my understanding my laptop NEVER had 98 on it... I'm praying this isn't a 98-xp upgrade. It seems someone gave me the wrong disc with my laptop?
Or am I worrying over nothing?

Hello Lou
Believe me you worrying over nothing!!! Please dont be confused about loading W98 message. The unit starts in DOS mode and it is the same as on W98.
Now step by step explanation: I have done recovery procedure many times and have a little bit experience with it.
When starts, recovery CD shows menu with two options: STANDARD and EXPERT installations modes. STANDARD mode simply erases the whole HDD and creates one partition (the whole HDD capacity) for OS installation.
EXPERT mode should be used if you want to install OS on already created partition or if you want to create new partition for OS installation. Please note you can create just first partition there ( C: ) and you can not modify already created partition.
In my opinion it is always good to have two partitions, the first one for OS and installation and second one for data saving. You can not always have external HDD with you. If something goes wrong you can anytime install OS on first partition without loosing data saved on second one.
Anyway, start recovery procedure and choose STANDARD recovery procedure (option 1). The whole HDD will be formatted and Os will be installed on one partition.
Bye and if you have more questions please write again.

Bootcamp crashed removing partition, now stuck with 60GB "Free Space"

I have a MacBook Pro Retina, 15-inch, Early 2013 with a 250GB hard drive running Mavericks 10.9.3
I use to have a 60GB windows partition setup via bootcamp, but I haven't used it in a while and wanted the space back. Bootcamp crashed half way through removal, and now I have a 60GB of Free Space that I am unable to resize the existing Mac partition into, nor can I use that space to create any new partitions. I try and no error appears, yet when I leave the partitions tab it says I've got unsaved changes.
I've gone into recovery mode and run a repair disk, and to resize it while still inside recovery mode. Nothing seems to help.
Does anybody have any suggestions?

Remove partition key from partitoned table

can somebody help me with a sql syntax to remove a partition key from a partiton table . The scenario is explained as follows:
create table t1 (c1 number, c2 number ,c3 number)
partition by range (c1, c2)
(partition p1 values less than 11,
partition p1 values less than 21,
partition p1 values less than 31 );
i have data in this table and lot of indexes built, so i cannot drop this table to recreate it.
All i want is to remove c1 from partition key (c1,c2).
I will appreciate if somebody can give me a SQL syntax for this.
Ajay Nerumati.

Have you used the debugger and checked that the selectedRowKey is filled?
Can you elaborate what you mean by {qoute} ...does not work ...>
Do you have a reason not to use the current selection listener selectionListener="#{bindings.NotificationOfDifficultiesVO.collectionModel.makeCurrent}" on your table to let the framework do the work for you and then simply call the delete method on the VO?
