HT1338 cannot mount my external hard drive can anyone help?

I was using an external hard drive to store my photos and had set up mac to upload pictures to the drive. was fine for 3 years suddenly its just gone. I've run disk Utility and it says everything is fine but the drive will not mount even after repair.

Odd, it seems. In the Finder "Get Info" display, you are seeing something like this?
Click the "Details" triangle and then the little padlock, and you should be able to change the permissions. Click the lock when you are done and close the Info window.

I am running 10.5.2 from a USB, I need to mount my internal hard drive, can anyone help me?

Hi everybody. My imac suddenly died on me. It couldn't start, right after the apple sign appeared, an interrogation sign showed. I ran the disk utility, and the problem was that the internal hard drive was not mounted. I installed the 10.5.2 (the one it came with the imac) in a USB flash drive, which I am running now. Is it possible to mount my internal drive so I can back up my data? (I know should back my data up regularly, but I didn't). Any help would be greatly appreciated.
Best regards,
Alvaro.

I suspect a failed HD, in that case I'd recommend Apple Hardware Test in Extended Mode at least 3x. You will need the original install discs that shipped with the computer, if you do not have them any longer you will need to order a replacement set from Apple by calling AppleCare. You will need a credit card and the serial number of the machine. The cost should be nominal.

MacBook Pro 2010: Flashing folder w/? on not responding to startup keys & I'm trying to install a new hard drive, can anyone help?

MacBook Pro 2010: Flashing folder w/? on not responding to startup keys & I'm trying to install a new hard drive, can anyone help?

Thanks. It started up com that disk but when I went to install it had an error message (didn't get to write out what it said). So I attempted to restore from time machine but it said there was no space, even though it's a new (replacement under warranty) HGST 1TB HD, so I did what I think was right and tried to partition the disk but it now says 'Partition faild...POSIX report...cannot allocate memory'. im not sure what to do, and I'm trying to remember how the previous hd was installed and formatted for use but that was over a year ago now. Should have erased the hd first or something?

Laptop no longer can mount my external hard drive

After updating to Mavericks, my laptop no longer can mount my external hard drive. What on earth is going on here and how can I fix this?

The drive is spinning and I was using it the night before I updated my macbook. It is viewable in disk utility but not in finder, and attempts to mount it are thwarted. The problem is literally coincident with updating the mavericks. When I click verify it didn't appear to have any problems but I will retry when I am back at home and report the findings.
It is a Toshiba 1GB external hard drive and has adequate power. Lights are on, etc.
I have not checked on another computer as do not have one available, but that will be my next step.

Since I downloaded Maverick, I cannot find my External Hard Drive in the "Finder" area. I have to unplug all the time the hard drive to be recognized by my iMac. How can I fix this problem? Thank You.

Check Finderr->Preferences->General and ensure that HDs are selected for display. If so and they still don't, Reset the NVRAM/PRAM and Reset the SMC, and see if that does the trick.

I have just upgraded from a Macbook to a Macbook Air. I have been using a iomega external hard drive for Time Machine, which use a Firewire. However, Macbook Air's do not have a Firewire port and i cannot find an adaptor anywhere. Can anyone help?? Thanks

There has never been a reliable firewire ---> USB adapter suitable for external high speed storage. This was a major issue when the MacBooks lost the firewire port a number of years ago (Apple subsequently brought it back).
The only high speed port on the Air is the ThunderBolt port. There are external ThunderBolt drive options out there, but they're somewhat more expensive than traditional USB/FireWire options.

Can I mount my external hard drive which will be compatible with both Mac and Windows?

Hello,
Can I mount my external hard drive which will be compatible with both Mac and Windows? If yes, then please let me know, because I intend to use my hard drive for both Windows and Mac, without losing any file.

Yes. By default, Mac OS X and Windows can read and write drives which are formatted as FAT32 or exFAT; NTFS drives aren't writable from Mac OS X without additional software.

My MacBook Pro won't let me mount my external Hard Drive. Just trying to restore my iTunes library.

My MacBook Pro, less than a year old, started acting weird. I backed everything up, took it in to Best Buy, who sent it out to Apple Repair and they put in a new motherboard.
It's running on Mac OS X Version 10.7.4
Now I am trying to put everything back on the computer from my external Maxtor 80GB Hard Drive. MacBook Pro won't recognize the external drive.
I tried Disk Utility. I can see the external drive, and did a repair disk and verify disk. Several times. Each time it says "This partition map seems to be ok."
However, I am not able to mount it, as that option is greyed out and i can't select it.
Also, under the Icon for the external hard drive, it has the Macintosh HD Icon (essentially my computer). I tried to restore this way, didn't work.
I need this to mount, as it has all of my itunes stuff on it; dozens of my sons movies, and my entire iTunes library.
PLEASE HEEEEELP!! HOW CAN I MOUNT THIS EXTERNAL HARD DRIVE? Thank you in advance

Try things in this USB/Firewire faq.

I cannot connect my external hard drives (1 WD My Passport and 1 LaCie Porsche Design). The drives were connected and worked perfect, the WD is used as a Time Capsule, the LaCie is formatted as exFAT and used for miscellaneous. They are both USB 3.0

I cannot connect my external hard drives any longer. I have one WD "My Passport" used as a Time Capsule and one LaCie Porsche Design used for all different kind of data, formatted in exFAT. They worked fine, connected direct or through an additional USB hub or also attached to a Dell monitor. The Lacie helds my iTunes Library and the iPhoto library.
After I moved the iTunes library to the external drive, from time to time the drive went into a never ending loop and I had to shut down the laptop (MacBook Air).
The last time starting again the drives were not recognized any longer. I tried to connect them to another MacBook, which didn't work.
Starting with Windows 7, the WD is also not recognized at all (perhaps because of time capsule format?) and the LaCie gives an error.
Could anybody tell me if there is a chance to get them alive again? When I connect them now, they start to heat up quite fast without anything else happening.
Thanks

Hi,
Just want to clarify, have you checked to make sure the cords are not damaged (going from hard drive to computer and or any power source )?
You have also check to make sure that usb ports are working correctly?
If you have checked these things it may be that the external drives have failed.
I would google the error message from the LaCie drive before I do anything.
There are several ways that I know of, one is to put the hard drive in the freezer for a while (make sure you wrap it air tight) if this works it is not a permenint fix. You might be able to transfer information to another source.
The other method is to plug the hard drive into a hard drive connector a product like this:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817707192
to do this you would have to remove the hard drive from its enclosure and still this is not a guarantee it will work.
The finally way I know is using a recovery service. This can be rather expensive, and there are no guarantees

I mounted my external hard drive to a pc and now I don't have edit or write permissions on my Mac (read only). How do I get them back without erasing the drive?

Hello all, I am a photographer and have my portfolio, edited and raw images backed up on a Seagate Free Agent External Hardrive. I mounted my external hard drive to a pc recently and now I don't have edit or write permissions to it on my Mac (read only). How do I get them back without erasing the drive and loosing my valuable work?

If you re-format it you will lose all the data on it!!!!! So make sure you have backed up the drive or moved all the data on it to another external HD or the internal HD on your iMac.
Below is an Apple Advice letter that explains how to format an external HD, it's written for Aperture but you can use the instructions to formate any external HD.

Hi Everyone. I have an old Mac Book. I have saved a ton of emails in my inbox 'On My Mac'. There are so many it is slowing down my computer. Where do I find the folder with all the emails so I can cut and paste them to an external hard drive?Pls.help.

Hi Everyone. I have an old Mac Book with software updated to 10.6.8. I have saved a ton of emails in my inbox 'On My Mac'. There are so many it is slowing down my computer. Where do I find the folder with all the emails so I can cut and paste them to an external hard drive? Pls.help. Tks.

Depending on which email client software you use
the files should be in 'your home folder' library, esp.
if you use Mail application.... ~/Library/Mail
Since you don't specify what mail application,
that would most be associated with the file.
I notice there are some items to the right of your post
where it says "more like this' so that may be worth a
look to see if similar issues were answered. Also, the
Help viewer in your system is a searchable database.
Seems that google also brings up fair information, too.
Do you have a complete bootable clone of your entire
Mac system on an externally enclosed hard disk drive?
Good luck & happy computing!

HT1751 if I move my iTunes library to an external hard drive can my computer access these files in iTunes or do I need to move them back to play music, watch movies, etc.???

If I move my iTunes library to an external hard drive, can my MacBookPro access these files in iTunes or do I need to move them backto my MacBookPro to play music, watch movies, etc.???
Trying to alleviate some disc space on my Mac!!!

Yes, it can. Launch iTunes with the Option key held down and navigate to that instance of the library.

Mount an external hard drive in single user mode

Do any know how to mount an external hard drive in single user mode:
I've issue the following command:
/sbin/mount -uw /
mkdir /Volumes/ex1
/sbin/mount_hfs /dev/disk2s3 /Volumes/ex1
(I've checked my external hard drive using df -k showing the device is disk2s3)
Result:
Permission denied

Hi leung wai,
   I wouldn't mind knowing the answer myself. I think the problem with doing it in the manner you attempted is that the device tree hasn't been created yet so the mount command is certainly not going to work. I assume that the answer is to start up enough of the system to have the device tree created. Unfortunately, I don't know where in the startup process that occurs. You could try the following command after making the boot volume writable:
/usr/libexec/registermach_bootstrapservers /etc/mach_init.d
Then check to see if the /dev virtual filesystem has been created. Of course it wouldn't surprise me if that didn't also mount your disks. If not, try the following:
/sbin/SystemStarter
It should have been created after that because at that point almost the whole system has started.

Is this external drive a Time Machine backup?
Then find what you want using Time Machine (or whatever application you used to make the backup).
Your iPhoto pictures are in the iPhoto library in Users/Pictures.
