New problems mounting an old external drive!

I have a 3TB external hitachi drive that has worked great. I have it formatted as MacOS extended Journaled. I haven't used it for quite a while I plugged it in today and I get a popup box:
The disk you inserted was not readable by this computer.
I initialize it and first of all - the imac only reads it as 801.57GB disc.
I cannot repair or verify the disk as I get this message:
Error: Partition map check failed because no slices were found
I'm kind of freaking out because I have 3TB of data on this drive that I'd like access to.
Any ideas how I can get my partition/data back?
***EDIT: I have multiple 3TB drives and all of them now seem to be affected by whatever is going on. I haven't used any of them in like the past month... Not sure what's going on.
***EDIT 2: SO I think I understand a bit more what's going on but not how to fix it. I have an external that has both esata and USB2.0 ports. Today, when trying to hook up the drive to my imac I was using USB 2.0. Usually however, I connect the drive to my imac via esata using a
Sonnet - Echo ExpressCard/34 Thunderbolt Adapter
I just tried using that and now the drives mount OK. Should I contact sonnet about this issue or can someone tell me when my 3TB drives would mount ok using esata and this adapter but not through USB 2.0. - Maybe I'm ejecting them incorrectly?

I am having a similar issue. I use an external Aluratek dock to connect my 3 tb barracuda drive to my Mac Pro using eSATA but when I try to connect that same 3 tb drive to my laptop via USB, it asks me to initialize the disk. It is unreadable. This is a serious problem and I think the issue is with Apple's OS as I have tried connecting the same drive via another portable USB dock and had the same problem.

New 13" MBP won't mount or recognize external drives via FW 800

Hi all,
I have a brand new 13" MBP. I have two external 750GB Lacie drives that were formatted for MacOS on my previous 13" MacBook. I mounted these drives via USB on the older laptop.
Neither of these drives will mount on my new laptop via the FW 800 ports. I've tested two cables on both drives and nothing works. Also, neither of the drives appear via disk utility when using FW 800. The drives do however appear when using USB.
Is my FW 800 port faulty? Could it be something else? Thanks!

Hi,
I'm having a similar problem to you - my external drive is not recognised by my MacBook Pro when using FW800 but it is when using USB2.
Did you have any luck getting your firewire to work properly?

Old external drive; how to check for virus?

I`ve an old external drive from the time I was a Windows PC user. I just don`t want a virus on my macbook, so I want to make sure that the drive is clean, and wipe out all the deadly ****. So, what do I do? PS, I have really important stuff in there too, so I cant just reformat the drive.

Download and scan it with either Sophos or ClamXav. Not that Windows viruses can affect the Apple OS:
There are many forms of ‘Malware’ that can affect a computer system, of which ‘a virus’ is but one type, ‘trojans’ another. Using the strict definition of a computer virus, no viruses that can attack OS X have so far been detected 'in the wild', i.e. in anything other than laboratory conditions. The same is not true of other forms of malware, such as Trojans. Whilst it is a fairly safe bet that your Mac will NOT be infected by a virus, it may have other security-related problem, but more likely a technical problem unrelated to any malware threat.

Does your Mac have ThunderBolt ports?
There are ThunderBolt to FireWire adapters.
As far as I know there are no FireWire to USB 3 adapters.

MacPro won't mount Windows USB3 External drive

I have a macPro 2,1 and it won't mount a Windows external drive that is USB3. I've tried NTFS-3G but still won't see the USB3 drive. I thought USB3 was backwards compatible. Can anyone help?

WEll, Paragon tends to have kept up their NTFS drivers
Your Mac is using PCIe 3.0 controller which are iffy even on OS X and may not be seen by Windows (and my Windows PCIe 3.0 card doesn't show up or work in Mac OS).
If you attach it via USB2 it might show, depends really on the bridge used by the enclosure probably. It is has USB3 and eSATA and you have PCIe SATA (Sonnet E4P is expensive but works great in both platforms)

Problems moving library from old external drive to new one

I keep all my music on an external hard drive connected to my laptop at home. I am now spending several months away from home, and couldn't take my external drive with me.
I planned to handle this by using iTunes backup feature to put my whole library on DVD, then buy a new external hard drive to take with me, and sse iTunes backup feature to rebuild the library on the new external HDD.
However, I can't get the library to restore/re-load/re-import from the backup DVDs. The iTunes backup/restore instructions tell you to open iTunes then insert the backup DVD. When I do that, I get the following error message:
"The Disc "Backup2007-07-09" cannot be read. An unknown error occurred (-69)."
However, I can read the DVD using just going through My Computer, so I really don't believe it's a problem with the disc.
So, if this backup method isn't working, how can I re-create my library on the new hard drive? I have dozens and dozens of playlists, a lot of them smart playlists that depend on such things as play count, rating, and date added, so i really need to keep all my tags.
I thought of two possible work-arounds.
Plan A: Copy all the music myself (ie, not using iTunes) onto the new external hard drive, using the same filename and path as they had on the old external hard drive, then import the Library.itl file that's on the backup DVD (manually copying over the default one created by iTunes).
Would that work? The big annoyance of this plan, I should add, is that, looking at the files on the backup DVD, i can see that iTunes added a number behind each folder name (ie, "01 Al Green") and behind each album title (ie, "01 Al Green - Greatest Hits"). It seems to me I would have to go through and manually delete all the numerals in both artist and album names in order for the .itl file to point to the right place. That would take hours...
Plan B: (Really not a great plan, but I'm grasping here...)
Give up on the backup altogether. Keep adding music and podcasts to my library as is. All my music that is sitting on my far, far away home HDD will get the exclamation point next to it in iTunes. Then, when i try to sync the ipod, if i'm thinking this through right, iTunes will go ahead and add the new stuff to my ipod, but all the old stuff will just not copy over, and then at the end of syncing i'll get the error message to the effect of "itunes didn't copy song x because the file could not be found." This option is far from ideal, as my playlists won't update, but at least i'll still have the playlists.
Do either of these sound like they would work?
Any other suggestions?
Any help would be very much appreciated.

If you can you connect both external drives to the computer at the same time, it would be easier to use the "Consolidate Library" utility in iTunes to move (actually copy) your media to the new drive.
1- Open iTunes preferences and select the Advanced tab. Change the location of your iTunes music folder to a location on your new drive. Also select the options "Keep iTunes music folder organized" and "Copy files to iTunes music folder when adding to library". Close the preferences dialog.
2- On the iTunes menu, select Advanced/Consolidate Library. This will gather all your media and copy it to the new location (the folder you designated in step 1).
3- After the consolidation is complete, verify that your music still plays, and check "Get Info" on some items to verify that iTunes is looking at the new location.
4- Optional. Delete the original files on your external drive. Do this only if you are certain that everything copied over to the new drive.
5- Optional. Close iTunes and locate your "iTunes Library.itl" file. This is typically in your iTunes folder, which may be on your computer's drive and not the external drive. Move this file to somewhere on your new external drive. Next, hold the Shift key as you launch iTunes and you'll be prompted to "Create Library" or "Choose Library". Select "Choose Library" and navigate to where you put the "iTunes Library.itl" file. This is a one-time step that tells iTunes where to boot the library from.

Getting files from old external drive to a new one

I have a dying Acom ac powered 80gig external drive on my eMac and a powerbook that is running out of drive space.
The Acom has one USB and two firewire outputs, one firewire is hooked up to the eMac . The Acom is all itunes music (none from the Apple Store) .
I had an ex-friend set it up so I don't know squat about using external drives . I think I'll get the LaCie Mobile firewire . From what I've read it seems the best . Any other suggestions are welcome .
Is there a good tutorial somewhere on how to do this ? I would like to transfer all the music from the Acom to the new drive and be able to use it like I did the old one AND use it with my powerbook to do the same thing .
Will there be a problem with library ? In iTunes (4.7) I have "Create file names with track number " checked but I don't have "Copy files to iTunes music folder when adding to library" I don't really know what this does but it sounded like it took up space so I haven't ever checked it .
as mentioned the eMac is iTunes 4.7 using Panther and the powerbook is iTunes 6.0.2 using Tiger .

What you like to do can be done, but not using different main versions of iTunes.
The reason for this is, that the 'iTunes Library' file has different structures with different main versions and is not downwards compatible.
Unless you have a reason not to upgrade iTunes on the eMac, my advice would be to upgrade.
If you purcase music at the iTMS, using iTunes 6, you won't be able to play them on previous iTunes versions.
If you have MIDI files, don't upgrade to the latest iTunes 6.0.4, unless you own QuickTime Pro.
iTunes 6.0.3 and 6.0.4 are having troubles with them (iTunes: MIDI files cannot be converted in iTunes 6.0.3 and 6.0.4).
I have an G4 iMac running iTunes 6.0.4. and an G3 iMac DV running itunes 6.0.2.
My music is stored on an external drive and it is no problem at all to use it on both computers.
There are a few requirements however (more about that later)
My advice would be to take the next steps.
• Purchase the mobile drive and transfer the music to it, using the instructions in the 'Moving your iTunes Music folder' article.
You will still have a backup on your Acom (as long as it still is running) in case something might go wrong.
• Upgrade iTunes on the eMac
• Copy the 'iTunes Library' file from eMac to the new mobile drive, attach the drive to the Powerbook and copy the 'iTunes library' file from mobile drive to Powerbook. Read "What are the iTunes library files?" to find the exact location of the file.
• Run iTunes on the Powerbook. you should see the entire library as you saw it on your eMac.
A few things to consider and take int account:
Decide which computer to use to add and import music. This will make things a lot easier.
You can of course add music on both computers, but you have to swap the 'iTunes Library' over and over to keep the libraries on both computers synchronized.
Always attach the mobile drive to the computer, before running iTunes. If you fail to do so, iTunes will reset the 'iTunes Music folder location' to the default location on the internal drive on the computer. Unless you 'point' iTunes to the location on the mobile again, songs you add and import will then be stored on the internal disk.
Let know if you have further questions.

HT3275 New macbook, old external drive for time machine

I got a new macbook pro a few weeks ago and set it up using my last backup from time machine. I want to use the same external drive for backups but there is no room. Can I delete all of the old files from the old computer or do I need to keep them?

I want to use a 3 TB external drive for Time Machine to backup multiple 500GB hard drives in my Macpro. I have lots of large video files from HD cameras.
1. Will Time Machine backup all of the hard drives in the Macpro?
As long as they're formatted HFS+, yes. Be sure there's enough room, though -- Time Machine needs considerably more room than the data it's backing-up. See #1 in Time Machine - Frequently Asked Questions.

Old External Drive failing; want to clone it to new external drive

I have an iMac connected to an external hard drive that is showing signs of age, and I fear that it may be failing. I'm going to replace it today.
The external drive has 2 partitions: one for Time Machine, and another for what just refer to as "Extended Storage." I put my video files and the like there so as not to eat up space on my iMac's drive.
My new drive will be 750GB. Before I do anything else, I want to effectively clone everything on the current external drive to the new one. Having never done this before, I may be asking a dumb/easy question, but can someone guide me on how to go about doing this?
Also, if anyone has thoughts/suggestions on how I should go about partitioning the new drive, I would welcome them. For what it's worth, my iMac's internal drive is 160GB, and the current external drive is 400GB, which is split up 160 GB to Time Machine, and the rest to extended storage.
Thank you for any guidance you can provide.

Migrating Library From Old External Drive To New External Drive - How?

So my current external drive is filled to the max so I need to buy a new one. I have a lot of playlists (representing albums) but if I get a new hard drive, will the playlists and their contents be linked to the music correctly? If not, how am able to accomplish this to insure a flawless transition?

Problem cloning your old hard drive to a new hard drive / ssd

I followed the procedure (from Bimmer, and several googled results), on cloning a boot disk for my macbook pro 17" (A1229), circa 2007, and I have a cloned SSD (Kingston ssdnow v300/240GB) that boots in an external drive, but not internally. The original disk still boots fine internally, any ideas on what could be wrong?
Yes, I formated it using disk utility, yes carbon copy created a recovery partition for me.
Runnign latest Mavericks version.

The procedure for Mavericks is not the same as for Lion or Mountain Lion.
Make Your Own Mavericks, Mountain/Lion Installer
After downloading the installer you must first save the Install Mac OS X application. After the installer downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the leftside list. 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.
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.
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.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
3. Use DiskMaker X to put your installer clone onto the USB flash drive.
Make your own Mavericks flash drive installer using the Mavericks tool:
You can also create a Mavericks flash drive installer via the Terminal. Mavericks has its own built-in installer maker you use via the Terminal:
You will need a freshly partitioned and formatted USB flash drive with at least 8GBs. Leave the name of the flash drive at the system default, "Untitled." Do not change this name. Open the Terminal in the Utilities folder. Copy this command line after the prompt in the Terminal's window:
sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
Press RETURN. Enter your admin password when prompted. It will not be echoed to the screen so be careful to enter it correctly. Press RETURN, again.
Wait for the process to complete which will take quite some time.
