I have an external hard drive that was formatted by a PC and has files and directories etc. I want to format it and use it on my IMAC for backup but I can't seem to write to it nor can I delete current content. How do I initialize it for use with the MAC?
I have an external hard drive that was formatted by a PC and has files and directories copied to it etc. I want to use it on my IMAC for backup. I see it on my my IMAC . I can open files etc. But I can't seem to write to it nor can I delete current content. I don't care if I lose current content. How do I initialize it for use with the MAC?
You can't write to it because it's formatted as NTFS which OS X will read but not write to. If you want to continue using the drive with both a PC and OS X you will need to download and install NTFS-3G so you can then write to it from your Mac. You can get NTFS-3G at:

If you want to use the drive exclusively with your Mac then move the data off it and reformat it in Disk Utility (Applications - Utilities - Disk Utilities) as Mac OS Extended (Journaled.)

So, I have an external hard drive that was connected to my mac not able to access.
Under Disk Utility I was able to see it how ever I was unable to access it. So I made a partition thinking that might help. However I think it erased that the disk? Can I recover or undo? or remove the partition? what can I do to get the information from it?? Please help!
You have erased your drive, if this data is important stop using the drive immediately and contact a data rescue company, you may also try some of the data recovery software available, I have no recommendations for that stuff (I backup so don't have a need for recovery)

I have my iTunes library on an external hard drive that was connected to a PC, now I would like to connect that hard drive my new iMac and load the iTunes library onto that computer, can I do that? Looking for a solution that keeps me from re-ripping my CD collection.

I have an external hard drive that shows up in disk utility but Verify and Restore are greyed out.
I have an external hard drive that shows up in disk utility but Verify and Restore are greyed out. I am trying to determine what is wrong with the drive.
I need the data on the drive and it won't show up in Disk Warrior. I have tried different Mac's and different USB cords only to find the same outcome. When selected in Disk Utility the information read as such...
Disk Description : WD Elements 1023 Media Total Capacity : 500.11 GB (500,105,740,288 Bytes)
Connection Bus : USB Write Status : Read/Write
Connection Type : External S.M.A.R.T. Status : Not Supported
USB Serial Number : 575837314135304D36373132 Partition Map Scheme : Unformatted
As the drive shows in Disk Utility there must be some life left in it surely. There is a possibilty that the physical connection between the USB cord and the external drive is damaged but since the drive shows up I believe it's unlikely... before I give it to the pro's is there anything else I can do to diagnose the issue?Hello,
I have just experienced the same thing!
Although my external drive shows in Disk Utility, it does not show in Finder.
And the Verify/Repair buttons are also greyed out.
Also, although the drive is 2TB. DU shows it as having Total Capacity of only 4.14GB! (Which should be the Free Space).
I was wondering if you solved your problem, & if so, would you share your solution.
I´m afraid to Erase in case I lose all my Data on the drive.
Thanks in advance for your reply! -
Is there a possibility to recover erased files from an external hard drive that was reformatted by the Time Machine?
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.

I connected my external hard drive that was previously on my pc and everything read fine. I later went on it asked to format and won't read at all on either computer
Drive Preparation
1. If you are preparing an external or a non-startup drive, then open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. 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. -
How do i recover data from an external hard drive that was accidentally deleted? After I verified the drive, a message appeared that said my drive needed to be repaired. When I tried to access the drive again, the 700 Gigs of music is gone!
Stop using the drive immediately, un plug it.
Buy a copy of ProSoft DataRescue 4 and use it to search for deleted files. -
I have an external hard drive that I have been using for years. All of a sudden my mac will not recognize the external as a "save as" device location. But the external does show up on my desktop and I can open it to drag and drop items. What happened and how do I get my mac to rerecognize the device?!?!?
Hi,
Check Finder>Preferences>Sidebar, is it checked there to show external drives? -
I am new to MAC. I have an external hard drive that I used with my former computer running Windows XP. Can I reformat it to use with my new MAC? If so, how do I do it?
Yes you can. See the following:

I have an external hard drive that I have used as Time Machine backup, but not for a while. Now when I plug it in, computer says this disc is not readable.
I want to keep the backups on it and not erase and start over.
Thank you in advance.
GregorIt sounds like something went wrong with the drive. Did you drop it? How long has it been sitting around unused?

I keep getting "error occurred while attempting to import file *******. The disc your are attempting to use is full." I have an external hard drive that I moved files over to, but apparently they're also still on my hard drive? HELP!
So you have backed up the content of the computer's hard drive, too?
That usually is a great idea since it is possible to lose use of the system
if parts of it have accidentally been removed or get over-written, or the
main system files get corrupted, when the hard disk drive gets too full.
If you have not trashed the originals of your created content, that remain
after you made copies on an external hard drive or other device, then
that is what you'd have to do to reclaim the capacity still in use by them.
What are specifications of the hard disk drive? The unused capacity
verses the used, in GB? If the hard drive has less than 15 to 20%
free or unused capacity, you could run into trouble. Mine are 40-50%
unused hard drive space, so ample room is available for automatic
Virtual Memory to use that capacity as temporary swap file space.
This is helpful when the computer could use more physical RAM
memory capacity, but doesn't have it. Or if the RAM is maxxed out
and you can't add any more. Virtual Memory is part of OS X and the
system automatically can use as much as is available, but it is better
to be sure there is plenty of resources available to include chip RAM
as well as unused or free hard drive capacity for use as VM.
If for some reason your files in Trash won't go away when you empty
it, you may have to restart. Be sure you have not included any System
files in the content in the Trash, or the Mac may not start up later on.
You may have to boot the computer from the install-restore OS X DVD
and run Repair Disk from its version of Disk Utility, to be sure it's OK.
I'm guessing that by now you know enough about the vintage system
in the older hardware to figure it out, so I won't write about it now.
In any event... hopefully you can simply trash the files, but check them
carefully, & you may need to remove (copy to archive first) even more.
Good luck & happy computing! -
Unlocking external hard drive that was locked with time machine
I use a MBP Retina (Mid 2012) with OSX 10.9.4. I left the MBP at Apple for repair and they changed the mother card and reformatted my HD (SSD). Since I had a backup on a WD My Passport external drive I was not too worried to restore. I had clicked the option "password protected" on TM and therefore the external HD was password protected. I also copied pasted many files on the same external hard drive, in case TM would fail one day to operate I thought that I would still have my files ...
But I was very surprised that when I plugged in my external HD into my MBP it didn't recognize it at all. The external HD did not appear on the screen anymore. Nor in Finder. It appeared in Disk Utility but it could not be mounted. Basically it was impossible to access my data. After a while and talking with Apple Support on the phone we could reach a point where a window appeared asking me the password for the access to the HD. Unfortunately it didn't work. The . password was not recognized. Even though we had selected the right country with the icon upper right on the screen to make sure that we used the correct keyboard.
So finally I reinstalled completely the OSX (coming rom Lion all the way to the last OSX) on the MBP and finally I could restore it with my TM. I spent three days on this since it only worked with one OSX - don't remember honestly which one - and not the last one. Don't know why.
Anyway.
Today I have my MPB working but I miss all the files that are still on my external HD because I cannot access to it anymore. As I said the recovery happened all of a sudden with TM with a former OSX and not the 10.9.4. With this current OSX my HD does not appear on the desktop nor on finder. Nothing. It is locked by TM and I cannot even key in the password to unlock it. Useless to say that I have the password.
Any idea how to sort this out please ? ThanksThis might work. Courtesty of V.K.:
run the following terminal commands (copy and paste, please)
sudo chflags 0 /volumes/*
sudo chmod a+rx /volumes/*
you'll have to enter your admin password (which you won't see). that's normal. this should unlock your drives. -
Hi there this is my first question here!
I connected my external hard drive originally formatted on PC on my new Macbook. The first time I connected it I could see all my files but today I connected it and after I couldn't see any file nor even on my pc appears as NO NAME with a different name and nothing on it. I think was reformatted, any help to recover all my data?
It's really important stuff for meIf the Apple Store couldn't get files off of the drive, it is unlikely that you will be able to. If you have backups, those would be the best way to go. You could also try booting up the computer and holding down T to boot into Target Disk Mode. Plug the broken computer into another one with FireWire and see if it works to recover data from external hard drive. If you can see it, try booting up the broken computer while holding down Option. Choose Recovery HD from the menu, then choose to Reinstall OS X.
It is unlikely that this will work, because I'm pretty sure that the Apple Store would have tried this. You could try using expensive software to get files off the drive, but it would be risky and the results might not be any good.

Do I need to have an external hard drive that has a certain spindle speed, like 7200?
In the past, when I did audio or video editing, the specs on the software required a certain rotational speed if I were using an external hard drive. Most of the time it was 7200. Do I need to use a specific spindle rotational speed for Final Cut Pro, or will drive 5400 or above do fine?
That still applies today as well. Helps to also use faster connection ports like Firewire 400 or 800, USB 3.0, or Thunderbolt rather than USB 2.0.

I use my external hard drive to store all of my music, but now I can't save anything on it with my new Mac. Is there a way that I can reformat it or something without losing everything I already have on there?
I suggest to copy all your files in your external drive to your Macbook and reformat that external drive to Mac OS Extended Journaled or exFat.
Once you've done that - then copy all the files back to your external drive.
Do not format your external drive if you haven't copied whats in your external drive. You'll lose everything.
