I deleted my internal hard drive, its the first hard drive in the disk utility

Now that I have deleted my hard drive I can't do nothing, help please ASAP

If you have anything you want to recover that isn't backed up, read these directions:
https://discussions.apple.com/docs/DOC-1689
Otherwise, try booting with command R to see if it will restore the operating system that came with it.
If not, you'll need the original installer discs, or newer retail discs. Macs newer than March 29, 2010 but older than July 20, 2011 (or those that haven't had their model hardware updated since July 19, 2011) require AppleCare send you the original installer discs.
Apple provides a firmware update to support command-R booting for those Macs as well. But you have to have installed it before the erase happened.

Help needed. I have a 3TB external hard drive partitioned into 1TB's. I used one partition as backup for the main computer hard drive. But now it is greyed out as shown in the disk utility and its name changed, i dont know how that happened, i tried verifying and repairing it but had no luck. I also tried mounting and unmounting it but still no solution. Anyone to help please?

Looks bad. I would strongly advise backing up the stuff on the other two partitions as soon as possible in case the rest of the drive goes wrong.
Beyond that, Disk Utility has limited abilities to repair disks, DiskWarrior uses a different approach and might, emphasis might be more successful. It has certainly done the job for me in the past when Disk Utility could not.

I am trying to upgrade my hard drive in my mac book pro using the disk utility in an attempt to clone my old hard drive. I can only get so far, just before cloning may start and receive an "error 254" and can go no further. Any idea what this error is?

I am trying to upgrad the hard drive in my mac book pro using the disk utility in an attempt to clone my old hard drive. I can only get so far throughj the process where its about to start cloing when I get a message " error 254". Any idea what that means and how do I get around this issue so I can use my new hard drive? Thanks for your input.

Connect the HDD to your MBP. Open Disk Utility>Erase and drag the HDD icon inrt the Name field. The format should be Mac OS Extended (Journaled). Click on the Erase button.
Then try the clone process again. You may use Disk Utility>Restore or a third party cloning application such as Carbon Copy Cloner or Super Duper.
Ciao.

My MacBook pro won't recognize hard drive I put in it. It boots only to a white screen unless I boot to my recovery USB. If I do that then I can select my USB and my external time machine drive in the disk utility, so no problems there. But what do you

My MacBook pro won't recognize hard drive I put in it. It boots only to a white screen unless I boot to my recovery USB. If I do that then I can select my USB and my external time machine drive in the disk utility, so no problems there. But what do you think it is? It won't recognize any hard drive I put in the machine, so might it be the sata cable?

Boot the Recvoery USB, use Disk Utility to select the internal drive makers namea and size on the left.
Now select erase and select the midde option and click erase, it will take a bit to complete but it's best for the drive.
Now select Partiton tab, click the big box and Options: GUID and then Format: OS X Extended journaled and click apply.
Quit and you should be able to install OS X now with your Apple ID and password.

What OSX version is it?
Does holding alt key at bootup show any boot choices?
Does holding Shift key at bootup to boot in Safe mode do the same thing?

My Firewire drive isnt mounting - can be seen in the disk utility but not mounting.

I have an older MicroNet 500GB Harddrive that has always been picky about what cables it uses. I used it not that long ago to download a mass amout of files to transfer from one computer to another and it mounted no problem. My iMac is newer bought it last year and has the 800 FW port and the Mirconet has a 400 FW and 2 800 FW ports.
I have tried multiple cables 800 to 800, 400 to 800, etc. I can see the drive in my Disk Utility and have run the first aid protocols to no avail. It refuses to mount to my computers...
Any one have any advice before I spend $200-300 to extract the data at Best Buy.
Thanks so much for any advice.

Was the external hard drive connected to a Mac or PC, when you transferred the large amount of files to it? I'm wondering if it has a corrupted directory, and needs a third-party product like DiskWarrior (which is better than Disk First Aid) to straighten it out. It's possible that the FireWire bridge board in the external case is bad (which could explain its hypersensitivity to cables used). I wouldn't pay $200-$300 for data retrieval, before exhausting less expensive options, assuming that the drive's warranty has expired. Examine the case to see how it's held together - often the cover sleeve is secured to the rear plate with small screws that can be removed. Sometimes, one screw is covered with warranty-void tape, which can be peeled back/off. If it's a plastic case, you may run into problems. Some plastic cases have hidden snap latches, that require a special tool to release without breaking them. If you can remove the case's cover, you can access the bare drive. Remove its mounting screws (either on the side or bottom of the drive) and disconnect the data and power cables. With the drive removed, you can use an adapter like this one, which will adapt the IDE or SATA interface of the drive (whichever it has) for connection to a USB 2 port on your computer. This is a generic piece of hardware - you don't need to buy one marketed for use with Macs. If the drive doesn't have a mechanical and/or electronic problem, it should mount on the desktop.

I tried partitioning my HD to install linux, the installion was not successful and now I can't boot my mac, I tried internet recovery, it was not helpfull as the disk utility cannot delete the partition I created.

I tried partitioning my HD to install linux, the installion was not successful and now I can't boot my mac, I tried internet recovery, it was not helpfull as the disk utility cannot delete the partition I created. It was only showing me an error message "EFI files are missing", I realized that it is trying to boot from the new partition I created for the installation of the linux I intended to do.

It sounds like you may have multiple problems, but none of them are likely to be caused by malware.
First, the internet-related issues may be related to adware or a network compromise. I tend to lean more towards the latter, based on your description of the problem. See:
http://www.adwaremedic.com/kb/baddns.php
http://www.adwaremedic.com/kb/hackedrouter.php
If investigation shows that this is not a network-specific issue, then it's probably adware. See my Adware Removal Guide for help finding and removing it. Note that you mention AdBlock as if it should have prevented this, but it's important to understand that ad blockers do not protect you against adware in any way. Neither would any kind of anti-virus software, which often doesn't detect adware.
As for the other issues, it sounds like you've got some serious corruption. I would be inclined to say it sounds like a failing drive, except it sounds like you just got it replaced. How did you get all your files back after the new drive was installed?

Lacie Hard Drive Appears In Disk Utility But Not Desktop

Hello,
My Lacie hard drive was working fine till yesterday. It will appear in the disk utility but not on the desktop? I'm using a G4 with mac os 10.3.9. I have tried disconnecting the power and rebooting to no avail.
Any help?
Thank you.

Welcome to the forum.
Have a look at the comments on THIS THREAD. Perhaps there's something there that will help.

External Hard Drive showing in Disk Utility - but not desktop.

A little background:
Yesterday, I moved my shelf where I have my modem, Airport Extreme, Airport Express and an external HD connected to the extreme to be a wireless HD for all users to access. Everything worked great - no problems whatsoever.
Problem: I have reconnected everything exactly as it was and reconfigured it as it was and now the external HD is having issues. When connected to the extreme, I can see it in the airport utility, but cannot gain access to it in that way. When I connect directly to my macbook, it is recognized by the disk utility, but does not appear on the desktop.
I don't know if this may have caused the problem, but I carelessly, unplugged the power bar for which all the above mentioned hardware plugs into when moving the shelf. Now, everything works as it did, except I can't get the express to show up once it is configured (but this isn't surprising as I had to fight with it the first time I configured it - not uncommon I am told), and the HD is no longer accessible via the network, or when directly connected to my macbook.
Help! According to the utilities, the data is still on the disk, I just can't access it in any way.

From the Disk Utility, select the drive and click on the Repair Disk(not Repair Permissions) button. If the Disk Utility finds a problem it can't fix, DiskWarrior or TechTool Pro will likely succeed.

So I recently removed my partition so I can repartition but its telling me to do something with the disk utility I don't understand what I'm suppose to do?

Unless you tell us what it is telling you we can't help.

My mac can't find the volume" Data" on Time Capsule. Also Ican't find with the disk utility program the hard disk in the Time Capule; so I can't format the disk again. What can I do?

Deconnevt and then connecting the power tp the Time Capsule gives also no solution.
What can I do?

I listed the commands.. that is how you manually mount the disk.. follow exactly the commands I gave you.
In finder use top menu, go, connect to server.
Type in the following.
AFP://TCname or AFP://TCIpaddress (obviously you replace with the actual name or the actual IP address).
If that fails..
try
SMB://TCname
Here is the screenshot.
tardis4 being the name of my TC.
It should then ask you for your credentials.
And it should remember them in the keychain and be able to then get TM to connect.

HT4848 how to erase the disk utility from my usb portbalbe flash drive

how do I erase the disk utility from my usb portbalbe flash drive. I need the flash drive for other stuff and it isn't allowing me to do so.

Here is information on the recovery partition, includin how to remove it from a drive: http://reviews.cnet.com/8301-13727_7-20083166-263/managing-the-os-x-10.7-lion-re store-drive/

How do i run the disk utility to repair permissions:confused;

how do i run the disk utility to repair permissions
i think i hav the same problem as you all iv been
restarting and deleting and renstaling but nothing seems to work
the only thing i havent don is this repair prmission
thing can someone type some instuctions on how or lead me where to
go

are you using mac OS10.2 or later?
if so, this is what I did to solve this most frustrating
problem. Go to Applications/Utilities/Disk Utilities
In the Disk Utility window, click on your hard drive, make
sure you're in the First Aid tab, then click on Repair Disk
Permissions.
Once the permissions were repaired, I took the advice of
another user here on the forum and reinstalled Flash Player 6, as
it was the one that was working before I tried to upgrade and it
screwed everything up.
Hope this helps

Moving backups to new drive -- without using disk utility restore

Hello,
I have done some research on this already but I don't believe I've found the solution. I just bought a new media / backup hard drive, and I've moved my itunes library (over 100 GBs) to this drive. Now I have researched how to move the time machine backups to this drive, and know you can't just copy the files.
The instructions I've received tell me to use the disk utility to restore the old time machine backup drive to the new drive, however if I do that won't I lose the iTunes stuff currently on that drive?
Is there an easier way to move that data without me transferring the iTunes back to my laptop, and then restoring through disk utility, and then re-transferring the iTunes again?
thanks,
James

yes, you will. but it is also a VERY bad idea to keep other data on the same partition as the TM backup. first, this data will not be backed up by TM. if you value your itunes data you should have it backed up. also, TM is very buggy and there are too many situations when you need to delete existing TM backups and start from scratch. this should be done by erasing the entire TM partition. you should never delete any TM backups from finder. also, TM will eventually fill up the entire partition with TM backup. it will start bumping up against other data on the partition and you won't be able to put anything else on it.
the upshot is that you should make a separate partition just for TM. don't keep any other data on that partition. you can add a partition to the drive without disturbing your itunes data. type "create new volumes" in disk utility help to see how. however, that's not a good idea IMO as you'll have both the itunes data and the TM backups on the same physical drive. when the drive fails (and it will eventually) you'll loose everything.
Is there an easier way to move that data without me transferring the iTunes back to my laptop, and then restoring through disk utility, and then re-transferring the iTunes again?

All of a sudden our fairly new Air's memory is almost full. The disk utility lists almost 50 GB as "Other". What has happened to our memory?

All of a sudden our fairly new Air's memory is almost full. The disk utility lists almost 50 GB as "Other". What has happened to our memory? I am new to Apple products.

First, empty the Trash if you haven't already done so. Then reboot. That will temporarily free up some space.
When it comes to clearing space on a drive, you have to decide how much to clear.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of your data.
Although you may be told by other contributors to this site that you should keep some fixed percentage (such as 10% or 15%) of the space on the boot drive available, that advice has no basis in fact as far as I can tell. The amount of available space you need depends on your usage pattern. I don't know how much you should have, and I don't make recommendations based on what I don't know. It should certainly be more than 9 GB.
If your data collection is growing quickly, then, depending on the size of the startup volume, you may need more than 10% available space in order to avoid the risk of filling it up, which can lead to a boot failure. If your data is relatively static, you may need less than 10%. I've seen no evidence that there's a loss of performance when available space falls below any threshold higher than the one Apple recommends. Available storage space that you'll never use is wasted space.
If you're using Time Machine to back up a portable Mac, some of the available space will be used to make local snapshots, which are backup copies of files you've recently deleted. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as "Backups." The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself.
About local snapshots
Use a tool such as OmniDiskSweeper (ODS) to explore your volume and find out what's taking up the space. You can delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one.
Proceed further only if the problem hasn't been solved.
ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
Install ODS in the Applications folder as usual.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Triple-click the line of text below to select it, then drag or copy — do not type — into the Terminal window:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
Press return. You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up.
I don't recommend that you make a habit of doing this. Don't delete anything while running ODS as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means.
When you're done with ODS, quit it and also quit Terminal.

I deleted my internal hard drive, its the first hard drive in the disk utility
