Somebody accidently unplugged my External Hard drive from my computer without going to the interface and clicking on eject first. I got the whole "you may have data loose" message. How do I find out if I really lost any files?

That's pretty much it. Wanted to know if there is maybe a program or something that can let me know what the last things that got deleted is?

That is a general statement that is always made when any device is not ejected, not a specific one about your hard drive. All you can do is plug it back in and hope it works. There is good chance nothing will be lost.
There is no ready technique available to you to check the details of all of your files, you will just have to assume they are all there.
Unplugging a drive like that without ejecting it is most likley to affect a file when it is still being written to such as a large (media) file that takes some time to write. If nothing was being written in that split second it was unplugged, it is highly likely nothing will be damaged or lost.

I have an external hard drive from my time capsule that stopped working on me. I am attempting to access the data with a hard drive reader on my MAC. I am able to see the drive in disk utility and under system info USB. But I am unable to access the data.

I am able to see the drive in disk utility and under system info USB. But I am unable to access the data and it does not show on the desktop when connected.

Ok if disk utility was able to verify the drive I doubt there is any problem.. are you trying to open a TM backup??
You need to mount the sparsebundle then check the actual info inside the bundle.
Don't use disk warrior.. if the disk has verified then unless you deliberately deleted files there is nothing that is going to do.
Pondini has a lot of stuff about getting access to the sparsebundle.

But if you have copied info to the TC that is now gone.. and the disk is ok.. I am not sure.. the TC will not have deleted the files itself.

Transfer external hard drive from old computer to new iMac

Hi, just got my first imac(woo hoo) and am trying to transfer files from my old Maxtor external hard drive over to the imac. I also purchased a mac time capsule. Most of the files I am trying to transfer from the external hard drive are pics, videos and iTunes music that just wouldnt fit on my pc. Is there an efficient way to do this? Should this be transfered directly over to the time capsule or to the imac itself? Any help would be greatly appreciated!!!

Put the hard drive into an external enclosure so you can connect it to the Mac.
Enclosures for FireWire and USB are readily available. You can find only FireWire enclosures, only USB enclosures, and enclosures that feature multiple ports. I would stress getting enclosures that use the Oxford chipsets especially for Firewire drives (911, 921, 922, for example.) You can find enclosures at places such as;
Cool Drives
OWC
NewEgg
All you need do is remove a case cover, mount the hard drive in the enclosure and connect the cables, then re-attach the case cover. Usually the only tool required is a small or medium Phillips screwdriver.

Can't access iPhoto library on external hard drive (from Mavericks days) now that I'm running Yosemite on my Macbook.

I have an iPhoto library on an external hard drive (from when I had Mavericks), but now that I've upgraded to Yosemite, "Photos" won't open my iPhoto library. Ideas for how to import that iPhoto Library into Photos?

"Photos" won't open my iPhoto library. Ideas for how to import that iPhoto Library into Photos?
What is the file system of the external drive, and how is the drive connected? DO you get an error message? If yes, which message?
You can only open a library on a directly connected drive, formatted MacOS Extended (Journaled). If the drive is correctly formatted, hold down the alt/options key while you are launching photos, and then select your library from the Library Chooser Panel.
If the library is not listed in the panel, use the "Other Library" button.

Your drive is formatted with the NTFS file system. OS X can read but not write to the NTFS file system. There are third party drivers available that claim to add the ability to OS X to write to an NTFS partition. I have not tried them and don't know if they work.
The only file system that OS X and Windows can both write to natively is the FAT32 file system.

I have seen so much response about the Mountain Lion update slowing down computers. I am updating from Mac OS x 10.6.8. What can I do to ensure the upgrade will go fine? Do I unplug my external hard drive before installing, or keep it plugged in?

Also, I have the 08 version of iWork. Will this cause problems for the update? Can I update this AFTER I update the processor?

Welcome to Apple Support Communities
There's no reason to think that Mountain Lion will slow down your Mac. Just make a backup of your data before upgrading with Time Machine > http://support.apple.com/kb/HT1427
Also, check that your apps are compatible > http://www.roaringapps.com Upgrade them to a compatible version or delete them before upgrading.
The external drive won't make the OS X Mountain Lion installer fail, but it's better to unplug it during the upgrade.
iWork '08 is compatible with Mountain Lion. iWork '09 includes OS X Mountain Lion features and can be purchased at the Mac App Store.
To upgrade to OS X Mountain Lion, I recommend at least 4 GB of RAM. You can check how much memory you have in Apple menu > About this Mac

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!

External Hard Drive (from windows to Mac)

Hi Mac users!
I just moved from Windows to Mac and I'm very glad I made the switch. However, I am having some issues with my Win-Mac transistion. I have 3 external hard drives that I used under Windows to keep backups of my videos and personal files. Out of the 3 external hard drives, only one is recognized by OS X (10.5). I really need the other 2 to be recognized to transfer some more data to my new Mac system. Could you please help me to figure out what to do??
Here are some information on my 3 externl hard drives:
1 is a WD My Book (working fine)
1 is a La Cie Porsche model (Not working)
1 is a Ximeta (Not working)
I tried several USB ports, USB hubs. I have checked the Utilities to make sure the hard drive is not recognized/detected. Please, i need help to recover some important information and to complete my Windows-Mac transistion!
Thank you for your help!

I had to ask...I also have to ask, when you tried a USB hub, was it an externally powered hub? Sometimes a USB disk won't mount because there isn't enough USB power. However, Mac OS has always given me an explicit message to that effect...
If your LaCie came with a CD, you might use it to install drivers. In principle, that shouldn't be necessary, but is a possibility. If it is a drivers issue then you may be SOL for the Ximeta; glancing at their website--but not necessarily for the right product--they seem to claim that their hard drives require Windows. But I've never had to install drivers on a Mac to use an external hard drive.
It shouldn't be an NTFS issue because NTFS is still readable, just not writable, as you already observed with the WD. The filesystem(s) should still mount.

HT3275 Time machine at home and it will not allow me to remove the listing of my external hard drive from the excluded files list.

Please help guys, I have a Time machine at home and it will not allow me to remove the listing of my external hard drive from the excluded files list.
I am trying to use time machine to back up the hard drive. For backing up from Macbooik pro and Imac, there is no problem. It seems to not want to allow the external drive to be removed from the Excluded list and as such will not back up from it.
Is there a way to be able to transfer files (music, movies etc) to time machine, format the external drive then put the files back to hard drive?
Sorry it is a long winded question but it is driving me nuts that I cant sort this out.
The <Macbook and Imac are both running mountain lion.
Thanks Guys

As for the hard drive to which you have never been able to write, is it by any chance in NTFS format? OS X can read NTFS for importing files, but it does not contain code for writing on an NTFS volume. That's a choice, not a bug.
There is third-party software available to install NTFS-writing capability into OS X. An example is Paragon NTFS for Mac OS X. Another alternative would be to use a disk format that both Macs and Windows systems can use for both reading and writing; this would require either a new drive or erase the existing data.
If by "the new system software" you mean OS X 10.9 Mavericks, you may want to repost that portion of your query in the Mavericks forum at https://discussions.apple.com/community/mac_os/os_x_mavericks . I haven't made the leap yet.
I don't know what other problems you have been having, so I cannot comment on them. You don't seem to have any other recent postings on these forums.

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.

Can I bring files from a NTFS formatted external hard drive (from Windows XP 32 bit desktop) to my new macbook pro retina?

Can I bring files from a NTFS formatted external hard drive (from Windows XP 32 bit desktop) to my new macbook pro retina?

What are these files you are trying to copy over?
If they are program specific and there is no program on a Mac to read them then you'll have to find either a Mac version of that program or one that does the same thing and can read those files.
The file extension should not change just because you connect a NTFS formatted drive to a Mac computer. A Word Document is still a .doc/.docx ad the same for all other office type programs. Music files with an extension of .MP3, or whatever, should read the same on both system. Same goes for all other files like images with a .JPG extension.
Yes I would network them.
I would not use Migration Assistant. There is nothing on your Windows PC that can be used on the Mac other than your personal data files. No programs or settings can be carried over from Windows to OS X.

My Western Digital external hard drive suddenly stopped showing up on my macbook pro and it disappeared from disk utility. I have tried making invisible files visible but nothing has worked and my hard drive shows up on a PC but not my Mac anymore.

What is the manufacturer of the external and how old is it? Does it have its own AC power supply or is it USB bus powered?

How do you transfer info from an external hard drive from a PC to a Mac

How do you transfer info from a external hard drive from a pc to a imac?

Expanding on what Niel said, a Mac can mount and read just about any hard drive from a Windows system. It can't write to an NTFS-formatted drive without third-party drivers, but it can read them. So as Niel indicated, you should be able to just connect the drive to your Mac and drag-copy over whatever you want. If you want to save things from the Mac to that drive, then it will need to be formatted either as FAT32 or exFAT, or if it's NFTS you'll again need drivers.
Regards.

The device may be formatted for Windows, as NTFS. The format is readable, but not natively writable on a Mac. To write to the device, you must either reformat it (erasing all the contents) or install third-party software to enable write access to NTFS.

If you don't see the external HD when you connect it to the Mac, then you need to use Disk Utility to format the XHD to a FAT32 drive. Once done it will read on the Mac and PC without any problems.
