My external hard drive is no longer accessible

I went looking online for more information about my LaCie external hard drive no longer working, and I found several recent posts from other LaCie owners experiencing similar issues. I have to wonder if the issue isn't related to the last firmware download from Apple.
In the meantime, how do I access my external hard drive if I can't do so with either the FireWire or USB cable?

Welcome to Apple Discussions!
Check LaCie for firmware updates. Contact firewire AT lacie.com via e-mail and let them know you are having this issue. Get Prosoft Data Rescue and an empty hard drive that is at least as large as the LaCie, and attempt to recover information to it using http://www.prosofteng.com/ 's Data Rescue II. If it can't see the drive, try Alsoft Disk Warrior 4. And if it can't see the drive, the drive may either be coincidently dead, or unrecoverable to all but a handful of data recovery firms. Those can cost thousands. Hope you have another backup somewhere. It is always wise to keep at least two copies of your data at all times.

My WD external hard drive will no longer show up on my Macbook pro.

My WD external hard drive will not longer show up on my macbook pro. The light turns on and you can hear it running but it won't show up either in finder or in the disk utility. This happened a while ago but I really want to get all my photos off the hard drive. Is there anything I can do to get my computer to read it again or get my data off of it?
I don't have access to another Mac to test it.
Thank you

dead sata bridge card. very common problem.
see all about it here:
Your dead external hard drive is likely fine! Great hope for your 'faulty' external HD
verify HD on another Mac however, if same, dead SATA card most likely

My external hard drive will no longer connect to my macbook pro via FW800........Any ideas on how to solve this??

Reset the SMC, see this Apple note: http://support.apple.com/kb/HT3964
Also reset the PRAM:
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
In most cases, those two actions will fix the port issue. If it's still an issue, you may need to see if the external hard drive can connect to another system, to ensure it's not having problems.

My Toshiba external hard drive is no longer being recognised by my Macbook Air - solution?

My Toshiba external hard drive is no longer being recognised by my Macbook Air. The light on the hard drive is on, but it won't appear on my computer's desktop or anywhere else. How can I fix this?

Hi rivraff,
If you are having issues mounting an external hard drive volume, you may want to see if it shows up and/or can be repaired in Disk Utility; you may find the following article helpful:

Finder->Preferences->General->set show according to your wants.

Once I upgraded to ML, I'm now finding that my Seagate Free Agent external hard drive is no longer being backed up by Time machine. Do I have to wait for Seagate to update their drivers for this hard drive?

I tried your suggestion, and it's been giving me the message "Preparing for Backup" for the past 8 hours. Does this mean TM is backing up my hard drive? I'll give it a few more hours, but if nothing else happens, I'm not sure what else to do. I'm not sure if there are any new external hard drives that are compatible with ML yet.

Can Disk Utility see it?

My external hard drive is no longer connecting. I was getting a message every time I plugged it in that it needed to be reformatted so I tried to do so and now when I plug it in the computer does not recognize it. It only shows up in utilities...

Hey guys, I need some serious help. I have an external hard drive, iomega which apears to no longer work; I am sure it is something I have done and I cant figure out what! I am certainly not a computer expert and am in Turkey so I dont have access to a MAC store for assistance or anything like it. Yesterday I plugged my external hard drive into my MacBook and got a message telling me to refotmat. I looked up how to do so and through disk utilities thought I did it right. Now when I plug in the hard drive my laptop does not pick it up; the only place it shows up is in utilities, the same place I tried to repair and reformat. When I am utilities it looks like I have 2 hard drives, one under the other. One tells me the description of the hard drive, the other doesnt really tell me anything. So I erased both of them and I think that is where my problem is. Any help on how I could fix this? I tried to "mount" the one that is not "mounted but it didnt work....I dont even know what that means!!! Help!

When you erased the disk did you select Mac OS Extended Journaled as the format option?

IPhoto library on external hard drive will no longer open

I'm hoping that someone will be able to point me to a simple solution to my problem...
I'm running iPhoto 9.6 on a MacBook Pro (Retina, 13 inch, mid-2014). The OS is Yosemite 10.10.1. Because the flash storage is only 250GB I have my main iPhoto library (146GB) on a partition of an external 1TB Lacie Rugged drive. The external hard drive also has partitions for Time Machine Backup and SuperDuper Bootable Clone. I have a separate, much smaller iPhoto library on the MBP which contains recent photos.
Yesterday I failed to reconnect my MacBook Pro to the power source when I put it back on my desk. The result was that the battery went below 5% and the MBP turned itself off and also ejected the external hard drive (some time after I reconnected the power cable there were dialog boxes on my screen informing me that each of the three partitions had been ejected incorrectly). I waited until the MBP was fully charged before I tried to open my 'main' iPhoto library on the external hard drive. I received a message that the library would have to be upgraded to work with the computer (very odd, because it had already been upgraded last October when I upgraded from Mavericks to Yosemite and has been working without any real problem ever since then).
After some hours when the only message on the screen was 'Rebuiding Thumbnail Caches' I pressed Cmd+Option+Esc I saw that iPhoto was 'Paused' - that message subsequently changed to 'Not Responding'. I 'Force Quit' iPhoto but the iPhoto library will not open at all from the external drive.
As a test I quit iPhoto and re-started using the Option key and chose to open the iPhoto library which is on the internal drive and it opened without any problem.
I recall that it used to be possible to fix this sort of thing (perhaps not) by trashing the com.apple.iPhoto.plist file, however, I don't seem to be able to find it :-(
I'm really at a loss as to how I should approach this problem and I would be very grateful for any suggestions that can be offered.
Cheers
Tricia

Further update ....
I downloaded and installed iPhoto Library Manager and then chose Library - Rebuild Library. Unfortunately, when it had finished the result was 0 images in any file or folder. I checked the log (which is incredibly long) but here's the beginning of it which seems to indicate that the problem is that an essential file is missing -

After this each entry has a dialog that basically says the image file is missing from /Volumes/Pictures/iPhoto Library.
As mentioned in an earlier post I do have another iPhoto Library on my 2008 MacBook.
Can someone advise the best way to proceed? I'm thinking that I should erase the partition of my external hard drive that is called Pictures and then connect the external hard drive to my 2008 MacBook and simply drag and drop the iPhoto Library to the Pictures partition. IIRC, that's the way I moved the iPhoto Library last October when I bought my new MacBook Pro which didn't have enough storage for me to be able to store my iPhoto Library on the MBP. I could then reconnect the external hard drive to my MBP and the iPhoto Library should reappear, shouldn't it?
Looking forward to more input ...

Updated to 10.4.10 and external hard drive is no longer readable...

I was asked to install a few updates today when I booted up. I d-loaded like a good little soldier and installed and now my external Seagate drive is no longer readable. The prompt asks me if I want to initialize, ignore or eject the drive.
Here are the updates...
1.) About iMac Software Update 1.1
This update provides important bug fixes and is recommended for 20-inch and 24-inch iMac models with 2.0, 2.4, or 2.8GHz processors.
2.) Keyboard Software Update 1.2
3.) iTunes 7.4.1 for Mac
4.) Compatibility Update for QuickTime 7.2
Is there anyone that would know why this is happening?
Thanks,
John

It's hard to imagine why those updates would affect your Seagate drive - the iMac Software Update 1.1 was simply an update to the graphics drivers, and the other ones are self explanatory. Have you looked in the system logs to see whether there is any clue in there as to what is failing? (Open the Console application to view the logs).

My external hard drive is no longer supported because of PowerPC app?

I am trying to back-up my computer to my external hard drive and a box is popping up saying "You can't open the application WD Backup.app because PowerPC applications are no longer supported." What does this mean? I have updated my system to Lion since my last back-up. Could this be the reason? What do I need to do?

Lion no longer supports apps that were written for PowerPC processors.
WD Backup is a utility that came with your Western Digital hard drive.
You may want to visit the Western Digital Web site to see if the have an updated version of their bakup utility.

Hard Drive (Internal) no longer accessible, icon no longer on desktop!

I was in the process of switching startup disks, which I have done on occasion previously without incident, then the drive was stuck on the startup screen, I pressed the restart button on the front of the computer and have not been able to access the drive since. The icon for that drive no longer appears on my desktop. I have attempted Mucho different things to retrieve the drive to no avail :
1. disk util from internal drive
2. disk util from Tiger DVD install disk
3. TERMINAL Application
4. PMU reset
5. NvRAM reset
6. Removing DRAM then replacing the same memory cards
7. Moving the hard drives around to different bays within the tower
Disk Utility reads (-9972) error when attempting to repair. TERMINAL App. responds with INVALID NODE STRUCTURE VOLUME CHECK FAILED. System profiler does recognize the drive though I currently have no access to the drive.
Drive has many very important files which I had not yet back-upped! I feel like I'm the next person in the group circle to state my name and admit I have a problem not taking disk back-up seriously.
Any assistance would be greatly appreciated before, if necessary, shelling out mucho dinero$ for disk repair and file retrieval.

Thank you for replying
I have the jumpers set as follows: original hard drive as master-jumper vertically to far left; hard drive that is not accessible (Macintosh HD1) jumper positioned horizontally-top row-offset one row past left as diagramed on the hard drive exterior; 3rd hd connected to pci card with ata connection-jumper vertically to far left. After nothing else has resolved the issue Disk Warrior is something I have considered.
Again thank you for replying,

External hard drive taking really long time to reformat

I'm reformatting a Seagate 2TB external hard drive that connects using USB 3.0 to my 2014 Macbook Pro (OS X 10.9.4).
For some idiotic reason (because I had never used it before and wanted to see what happened), when I went to reformat the drive in Disk Utility from FAT32 into 'Mac OS Journaled (Extended)' I selected the option for "7 Pass Secure Erase". It initially told me it should take "1 day, 7 hours", which seemed like a lot but was consistent with what other Support Communities people have said for such a large drive.
It's now been reformatting for 20 hours, and the estimated time remaining says "1 day, 1 hour". The progress bar has moved and it says it's on pass #3, but this seems like it's taking an abnormally long time. Has something gone wrong? For reference, I did a 1-pass into reformat into FAT32 on a similar 1TB external and it only took me around 20 minutes (so I estimated the new one would take ~5 hours (20 * ~2X storage space, 7 passes). I know "estimated time" on a computer always defies the laws of mathematics, but if "6 hours" is actually 20 hours, will I really be waiting for another 80 hours? Can I do anything to speed this up?
More importantly, can I stop the reformat and try it a gain with 1-pass, now that I've initiated the idiot way of doing it? I don't want to screw the drive up or make it unreadable, it's brand new, but I don't want to have to leave my laptop on for the next 3 and a half days.
Please help! Thanks so much!

I don't know which Seagate external you're using but my experience with a number of GoFlex externals has been that very little thought was given to ventilation, and, as a result, the drives tended to overheat. Watching the transfer rate using Activity Monitor during normal backup use, I found that after running a while and getting hot, the transfer rate went from MB's to KB's/sec. You're not actually transferring anything but the drive is being written to, so I'd expect the write speed to drop and what is already going to be a long process will just get longer. Sorry.

My external hard drive is no longer recognized by my Mac

I have used Time Machine and a WD external hard drive to back up my computer for several years. Now, when I connect the hard drive, the drive lights up as though it's working, but the connection does not appear on my Mac -- the external hard drive is not listed in Device (in Finder). Any suggestions?

power feed issues and data appearance/disappearance are both symptoms of the SATA bridge card,..arguably the most failing modern computer component made.
throwing more power to the drive wont fix that.
SATA bridge card as found inside all USB HD devices which has an extremely high failure rate.
Inside a USB hard drive, containing the HD and SATA card
Countless 1000s of good external hard drives are thrown away each year because the owner thought the HD was bad when it fact it was the SATA bridge card which had failed. This card is removed in a matter of mere second once an external USB HD is cracked open from its plastic casing to reveal the bare HD and the attached SATA card which attaches between the HD and the USB cable.
quick and easy option is to crack open the WD USB drive, and remove the SATA card, and put the WD drive into a new enclosure ($20)
HOWEVER, if its an OLD WD drive, the SATA interface is permanently attached to the HD and the OP is "out of luck".
