How do I erase and external HD that won't mount?

Help! I bought an Iomega eGo drive from Amazon. I backed up my MacBook Pro and my work on this drive. Now it won't mount and I want to send it back to Amazon. I tried disk utility, Disk Warrior and plugging it into other Macs. It has firewire 400 & 800 and usb. Nothing from all of them. How d I get my personal stuff off so I can return this hunk of junk? (my 2nd one! I never learn.)
Any help or ideas would be very much appreciated!
Thanks!

Just to add to the previous, if you use "System Profiler" (in your Utility Folder) and look under which ever interface you have it connected through, does the "bridge" in the enclosure itself at least appear, even if the drive itself doesn't? If it DOES, then the problem either lies with the drive or with its connection to external enclosure's "bridge". If even the "bridge"/ enclosure itself doesn't appear then the problem is either with the bridge/enclosure itself, the cable you are using, or the port you are using on the Mac (as the drive doesn't surface under any of three connection methods you can pretty much disregard the last two).
If the bridge is dead, then the only way you will be able to erase the drive is by removing it from the enclosure and putting it in another one (which will almost certainly void any warranty).
If the bridge appears, but the drive does not, then it is probably the drive itself which is dead, in which case you won't be able to erase it anyway, but no-one is likely to bother going through the expensive and time consuming process of seeing what is on it by removing platters etc! Most techs in the warranty departments of major companies like Iomega are overworked, underpaid, and trying to avoid additional work. They just won't be interested in the content. Dead drive, into the bin, onto the next one! As you say yourself, such failures with Iomega drives unfortunately aren't exactly worthy of headlines!
If Disk Utility can "see" it, though, even if it won't mount it, then there may be some other options for wiping data before sending it back.

How do I repair a damaged dmg that won't mount and Dick Utility can't repair?

Apple Care gave me wrong instructions on how to create a disc image of my internal HD then erased it. Now I have a .dmg that has the same gigs as the HD but won't mount and Disk Utility can't repair. Tried to recover files with Data Rescue 3 but that isn't going so hot. Any suggestions?
Thank you

The Apple Support Communities are an international user to user technical support forum. As a man from Mexico, Spanish is my native tongue. I do not speak English very well, however, I do write in English with the aid of the Mac OS X spelling and grammar checks. I also live in a culture perhaps very very different from your own. When offering advice in the ASC, my comments are not meant to be anything more than helpful and certainly not to be taken as insults.
I guess that it's a moot point to ask if you didn't test the dmg before you erased the drive. Do you have a Time Machine or other type of backup?
If not, it's a hard lesson to learn, but I would guess that unless you are willing to pay for expensive outside data recovery service, all is lost and you are starting over.

How do I disable journaling on an external drive that won't mount?

I'm trying to fix a hard drive that gives me the "Invalid content in journal" error. I've run the latest TechTool and Drive Genius and they say the drive is fine, except for its crippling inability to actually mount. Onyx and Cocktail won't touch it until its mounted. Ideas?

It's possible to recover files 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.

How can I erase a photo album that was uploaded from an old computer that I don't have no more? I have other albums in the Iphone that I don't want to delete.

How can I erase a photo album that was uploaded from an old computer that I don't have no more? I have other albums in the Iphone that I don't want to delete.

If you sync with the new computer it will erase the current content from the iphone and replace with the selected content of the new computer.
The pics that you have taken with the iphone should be imported regularly to your computer as you would with any digital camera. You can then organize them and sync them back to the iphone if you wish.
If you have had itunes perform a backup on the new computer, you should get the pics taken with the iphone back, but I would import them before trying anything.

How do I erase the "other" files that are occupying my computer

I already deleted pics, music, etc and I am ready to continue to delete unnecessary files. How should I erase the "other" files that are in my computer. Please, advice. Thanks

For information about the Other category in the Storage display, see this support article. If the Storage display seems to be inaccurate, try rebuilding the Spotlight index.
Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Do the same in other applications, such as Aperture, that have an internal Trash feature. Then restart the computer. That will temporarily free up some space.
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—not the mythical 10%, 15%, or any other percentage. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) or GrandPerspective (GP) to explore the volume and find out what's taking up the space. You can also 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. Note that ODS only works with OS X 10.8 or later. If you're running an older OS version, use GP.
Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS or GP 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.
If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
Install the app you downloaded in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the corresponding line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
sudo /Applications/GrandPerspective.app/Contents/MacOS/GrandPerspective
Launch the built-in 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.
Paste into the Terminal window by pressing command-V. You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. Ignore any other messages that appear in the Terminal window.
The application window will open, eventually showing all files in all folders, sorted by size. It may take a few minutes for the app to finish scanning.
I don't recommend that you make a habit of doing this. Don't delete anything 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 in doubt, leave it alone or ask for guidance.
When you're done with the app, quit it and also quit Terminal.

How to avoid erase and sync when choosing to manually manage media?

I have bought a new iMac and formatted my old Macbook. Now, I am starting with a new iTunes library. I want to add more songs to my iPhone manually (choosing the new ones and adding them and leaving some out) without erasing and syncing, as that would erase my entire iPhone of all my hard-earned purchases. PLEASE help!

Did you backup all your documents and data first? Normally your user profile contains a Music folder which in turn holds the iTunes folder. All the important details of your library are in there, with the media below in a folder called iTunes Media. If you lose this information and then connect your device to an empty iTunes library it will want to clean out the device and start over. Switching to manual management carries the same penalty, at least as far as the media is concerned.
You should be able to transfer your purchases into a newly authorised library, backup the device, recover any non-store purchased media with the tips in this post from forum regular Zevoneer, then restore the device from the backup you just made. That should preserve all your data and switch the assocation of the device to the new machine. I've had positive feedback on this method from other users but I've never had to test it personally as I backup my library.

How can I open and edit files that were developed and published by ftp to my host on my old macbook, which I can no longer access.

How can I open and edit files that were developed and published via ftp to my host on my old macbook, which I can no longer access. The HD containing the files cannot be accessed. I want to be able to download the published files to be edited in iweb?

You CAN'T download published files and then edit them in iWeb because iWeb can't open them - it has no import facility so is unable to open any html or css files - a previously published site.
You can download these files yes, but you'll need to use them as a guide or to cut and paste text from there whilst you re-build your site in iWeb.
The only other way is to download the files and then open them with an html editor such as TextWrangler or use one of the other web design programmes out there that is capable of importing html and css such as Dreamweaver of Flux 4.
These are your only alternatives as iWeb can't import and if you want to continue to use iWeb, then you'll have to re-build your site from scratch. If you do just remember to back up your domain.sites file this time around - it is found under your User/Library/Applicaion Support/iWeb/domain.sites.

Iphoto won't down load because My mac is a lion 10.75 I need 10.10?how do I download iPhoto, and other apps that won't download?

iPhoto app won't down load because My mac is a lion 10.7.5 I need 10.10 ? how do I download iPhoto, and other apps that won't download? They were uninstalled by mackeeper (with me as an unwitting accomplice Thanks
I've reinstalled lion os 10.7.5 and got the app store app back.
Even though iPhoto etc are purchased by me in app store, theres no way they'll download.

then
reinstall from the original source
Could be
1 - the restore disks that came with the computer - if it came with CDs and you do not know where they are then contact Apple to see if they can be replaced
or
2 - the iLife DVD that you purchased
or
3 - the app store - log in under the Apple id used to purchase the software or to set up the computer - look under purchases - you might have to unhide or accept the Application first

How to easily delete songs from itunes that won't sync?

I just bought my first ipod (a 32Gb Touch), however I have been using itunes for about two years and have about 4100 songs in itunes.
After my initial install years ago, I tested the sync with a friends ipod. Now there are about 100 of these songs in itunes that were his, which prompt me that they can't sync everytime I sync my Touch.
I would like to just delete them, but I don't see any way to sort or select these 100 songs in a group to delete them and I dread the idea of going through my large song list and deleting them one at a time.
Does anyone have an easier way of mass selecting and deleting songs that won't sync? I wish itunes would let me do thins right from the list it was showing me, but no luck.
Thanks!

Sort by *Date Added* and they should all be at the same place in the list.

External firewire drive won't mount

I've got an external Western Digital firewire drive that's been somewhat flaky recently, and today my Mac won't mount it.
When I open Disk Utilities, I can see the drive (along with the other drives daisy chained together). When I click on "mount," I get a message saying the drive can't be mounted and that I should try running disk repair. I've run both repair disk and verify disk a few, and each time it says that everything is just fine. However, the drive still won't mount.
Any thoughts about how to get the drive working again?
For what it's worth, this drive is basically my manual backup drive that I use each day just as a safety backup. I don't think I'm going to lose anything extremely important if this drive is dead or if I have to try erasing the drive, but I'd like to see if I can rescue it first before taking drastic action like that.
Thanks!

Dale,
That sounded like a brilliant thing to try. I took the drive out of the daisy chain and plugged it into the unused firewire port in the computer. I ran the repairs and crossed my fingers, but came up with the same thing
At least I've eliminated one more option. Wish I could mark your reply helpful, but I'm not seeing that option available . . .maybe I've used my "helpfuls" for one day.
Although this is PROBABLY duplicate material on this drive, I'm going to hold out for another day or so in case anybody else comes up with another brilliant idea before I take the plunge and reformat the drive.
Thanks!

External Lacie drive won't mount

I have a older Lacie 160GB LaCie P3 extrenal drive that I can't mount. There never has been an issue with mounting it before in the method described below.
Here is what happened:
I turned the drive on but the firewire was not connected so I turned the Lacie drive off.
I connected the firewire and turned the Lacie on and the (partitioned) drive mounted on the desktop.
I was looking through the files when I got the error message that the drive was disconnected without being properly ejected which I didn't do.
I tried turning the Lacie drive off and on but it won't mount. I get the same flashing light on the Lacie drive that I had before connecting the firewire.
I tried Disk Utility but it can't see the drive.
I tried connecting to my laptop but it doesn't mount there either or show up in disk utility.
Questions:
Any idea how I can get it to mount?
Is there any risk of damage to the data by turning it on and off in an effort to get it to mount. I can hear it running.
Thank you

LIkely (very) your SATA card is fried inside the box for same.
External HD are very easy to diagnose. Bad USB cable (on commercial sold USB drives) almost doesn’t exist anymore.
External USB HD have 4 'parts' (not counting the HD internals)
1. USB cable (never an issue anymore, approaching 100%)
2. HD enclosure.....a plastic or metal box which cannot ever be an issue.
3. the HD itself
4. ....and last but not least is the epicenter of 'weak links' ,.....a SATA card/bridge that is connected to the HD inside the HD box, the size of a stick of gum, with SATA female on one side, and female USB on the other side, containing circuitry for data transfer between the SATA on the HD and to USB on the other.
While these bridge cards are better than they used to be, theyre still insanely unreliable.
There are literally probably MORE than 100,000 perfect external hard drives out there thrown away every year because people assume the "hard drive is bad" when really they could crack open the HD enclosure, remove the HD and put the good HD into a new enclosure.
See this video of the SATA CARD, its at 8:55min. http://www.youtube.com/watch?v=2pS_EDsP2KI
All conventional HD external are nearly 100% like the video above.
See pic below,..a (much larger) SATA card as found inside a typical HD enclosure ($20 ebay)
This is the nasty piece pictured below causing all the "crazy" activity seen on external HD, very odd behaviour, some have called it "haunted hard drive syndrome". Random ejects, random strange vanishing of the HD , especially in mid transfer of data.
the card attached to the TOP of the HD plugs in, that the SATA bridge
