Hello, I need help to retrieve deleted information to partition an external hard drive. What should I do?

I'm not about the question, and giving you the right answer requires me to ask a few more questions.
Do you want to retrieve deleted information for future usage, or to completely delete a partition? The latter is straightforward: simply erase the partition. The former is more complicated: it's very difficult, even using available commercial software, to recover deleted information. If the data is important, you may want to contact a professional like DriveSavers. It won't be cheap.

Need help recovering .dmg files from an accidentally reformatted external hard drive

Help?
I went to make a copy of an important drive and accidentally re-formatted it (re-formatted mac journaled, originally mac journaled). The drive contained a bunch of important disk image files which I need to retrieve whole. I'm fairly confident that the files are still there and only the table information got overwritten, as the re-format took about 30 seconds. None of the recovery software I've seen however, can retrieve .dmg files, or such large files (these are up to 32 gb each in size).
Any suggestions on how I can retrieve these disk image files?

How to replace or upgrade a drive in a laptop
Step One: Repair the Hard Drive and Permissions
Boot from your OS X 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 Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) 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 click on the Repair Permissions button. Wait until the operation completes, 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.
Step Two: Remove the old drive and install the new drive. Place the old drive in an external USB enclosure. You can buy one at OWC who is also a good vendor for drives.
Step Three: Boot from the external drive. Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears. Select the icon for the external drive then click on the downward pointing arrow button.
Step Four: New Hard Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your new hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Step Five: Clone the old drive to the new drive
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Check the box labeled Erase destination.
5. Select the destination volume from the left side list and drag it to the Destination entry field.
6. Select the source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the new internal drive. Source means the old external drive.
Step Six: Open the Startup Disk preferences and select the new internal volume. Click on the Restart button. You should boot from the new drive. Eject the external drive and disconnect it from the computer.

I have an old Mac Tower. I need to move data from the unit to an external hard drive. What kind of hard drive do I purchase. There is not a lot of data to be transferred.

I have an old Mac Tower. I need to move data from the unit to an external hard drive. What kind of of hard drive must I purchase so that it works with the Tower? There is not a lot to transfer.

MG,
What we might need to do is to change the question. What computer do you plan to use the data on in the future? For example, if you have a newer tower, just move the hard drive to the new tower. If you want to use the data, what about an ethernet LAN to get the data over? If you want to archive the data, how do you store the second drive? What are your plans for the first drive? If the new software will not recognize the old file type, the data must be exported. Just getting files to another hard drive will not finish your journey.
As Allan said, knowing the exact model and year of your tower is important. My suggestion is to find a user group near you. Please post back with more information, including the name of a large city near you.
For example, our user group just experimented with a 1983 Apple IIc that predates the Mac. It started right up, read files from 1984 and saved them from a 5.25" floppy to a 3.5" floppy. That 3.5 floppy will go into a platinum G3 which will read PRODOS files using Apple File Exchange. That G3, with a USB card, will allow saving the files to a USB flash drive. But, somewhere along the way, some software has to read the file and convert it to data that is useable by current software.

HT201250 Do I need to partition my external hard drive if I'm using Time Machine and other storage?

I never used Time Machine before. I was storing select files on my external hard drive as well as using my libraries (IPhoto, ITune, IMovies) directly off of the external hard drive. That hard drive is giving me problems, so I bought a new one. I want to set up Time Machine on this one, but I also want to keep my active libraries on it. Do I need to partition the external hard drive?

You can partition the new drive, just don't make one of the partitons a TimeMachine drive, save a TM for a entire drive with more space than the boot drive as it saves "states" thus requires more room than most people expect.
I highly advise one drive to one drive for backups, and not placing too many backup eggs in one vulnerable hardware basket basically.
Drives are cheap, data is not. Hardware can fail just as often as software, so you need a multiple backup and storage stragedy to protect even against theft and fire.

I have an iMac purchased in May 2011. OSX Lion 10.7.3. I deleted backup file from the external hard drive which operates from Time Machine.
Now, the trash can will not empty some of the files deleted from the backup harddrive.
The trash contains-- File folder: "Core Services" which contains a locked file: "boot.efi".
It will not delete.
How do I get the trash can empty of these files?

Yes, the Old Master file has a folder for each year where I find all photos from that specific year. I am attaching a screen shot of the file.
In the meantime i have managed to download all photos (it did not download any video files though in mpg, avi, 3gp, m4v,mp4 and mov format) to a new iphoto library. Unfortunately the photos are quite mixed and often doubled up. I ma considering to purchase iphoto library which checks all duplicates in iphoto. this will save me a lot of time. What do you think?

I just bought a MBA and I need to move my photos and itunes to an external hard drive (from my old MacBook Pro) because they won't fit on the Air. I got the photos moved fine and I followed an online tutorial to move the necessary files for itunes, but it didn't work. The files copied fine, but when I tell iTunes on the Air to look at the external drive for the library, it doesn't find anything. What I copied was the entire iTunes Media folder. So, how do I move the necessary iTunes files from my old Pro to a external drive so I can access them from my new Air? Whew!

iTunes- How to move the library to an EHD
After you move the library you need to open iTunes by first depressing the OPTION key then launching iTunes. You will be given a choice of which library to use. This can then be made a permanent change, if you wish, in the Advanced section of iTunes preferences.

Deleting photos in cs5 bridge - external hard drive

I am trying to delete large numbers of images from an external hard drive through Adobe Bridge. I have tried dragging the images to the trash can. I have tried simply hitting the delete button with no luck. I have hit the delete button while holding the command key and nothing.
I really need to do this. If i can not in Bridge i will be disappointed but i will move on.
Please help in any way.
thank you in advance for you help.

Sounds like a good suggestion
On a Mac select the drive in the finder (either in the finder window or the
finder window side bar and choose cmd + i (or the menu file/get info)
At the bottom of this info window you can see if you have all the read and
write privileges.
On a Windows machine it is a permissions issue. Start Bridge by right
clicking and choose "run as administrator". This sounds a little stange if
you are a single use computer with full administrative rights, but it works in
a Windows machine, perhaps in a Mac also?

Help with restoring files from back-up to external hard-drive

My laptop died. Took it to Best Buy for evaluation. They had to send it out; but (for $150) were able to back up the laptop's data on an external hard drive.
I have tried to restore my files to the new laptop, but can't figure out how...except to copy them over. Need some help.
The external hard drive included Backup Now EZ. Thought it would be easy, but I am stumped. Tried the "restore" feature, but am missing the boat somewhere...because it didn't work.
Thanks.

That program is made by NTI.

Do I need to partition my external hard drive for a bootable backup

Hi - First, I apologize for asking a question that's already been discussed so much. I did try to read everything I could, but I remain confused. Here is my precise situation:
I have an iMac, and I purchased a year's worth of Carbonite's online backup and breathed a sigh of relief. Then I read some people have problems with Carbonite, and the best advice was to buy an external hard drive, which I did. It just arrived, I plugged it in, and Time Machine backed up my computer on it...so I breathed another sigh of relief.
Then I read that my wonderful new 2T external hard drive isn't good enough, that I should partition it so as to have one backup, and one "bootable backup." Is this really necessary? And what is the difference between a backup, and a bootable backup? If it is necessary, how do I do it? Is it a problem that I've already used it to create a backup on Time Machine?
I use my computer for things like email, Facebook, pictures, eBay, stuff like that. I have no unusual needs. My computer is an iMac OS X 10.6.8.
Thank you in advance for any help you can offer!

I prefer a clone/bootable backup ovver Time Machine myself.
For TM you need a running OS, then time to restore, with a clone you can boot from that & keep working while doing the other when time is better. And you can test a clone before you need it.

Cannot delete Time Machine file from external hard drive

Hello,
I'd like to delete my original Time machine file from an external hard drive ( Lacie mini ). I move the file into the trash bin and it constantly "deletes". At one time I left it deleting overnight and the file still wasn't trashed.
I am going to hook up Time Machine to a different, dedicated external hard drive, but I'd like to gain space on the drive that Time Machine is currently on.
I currently have Time Machine turned off ( I do have everything backed up with my home folder on another external HD ). Should Time Machine be turned on for me to trash the file? Is there a better way to delete the file?
Much thanks in advance.

But what if a person doesn't want to erase the TM drive? My MacPro came with tiger installed, but since tiger-intel-retail discs don't exist, my copy of tiger is what i have. I was all manner of foolish directing TM to that drive, but damage is done. What can someone in my position do?

I cannot pass information from my Mac to my external hard drive, what can I do?

Hello,
This is my first Mac and I am new to all of it. I have an external hard drive that I use to use with my old PC . On the external hard drive box it says its compatible with both windows and Max os x. I can pass files from my external hard drive to Mac but I cannot pass files from my MacBook Air to my external hard drive. No messages comes up or anything explain why it simply doesnt allow me to do so. What can I do?

Your hard drive is formatted NTFS for windows. That format is read-only from OSx. If it's not needed on Windows anymore, you can use Disk Utility and format it for the Mac. Mac OS extended (Journaled) - Partition Map scheme of GUID Partition table.
Make sure to save any data from the drive as it will be wipped doing the above.
