I used dd overnight to copy a suddenly unmountable GB drive to a directory on a GB drive. The resulting DMG file shows up fine. When I double-click to mount the image, though, I first get a "file may be damaged; do you still want to open? I confirm the open, but then I get a result of "no mountable file systems. I found this hint to be extremely useful. For some reason the recovery. Thanks for an informative, and useful hint, that netted a great result using the command line.

So I've crated a dmg file using dd as described but now excuse my ignorance how do I write a bit for bit copy to a new hard drive? If the later is the case, what would the command be? Do I just swap the input if and output of names? Thanks for any help. The command I give. Not a directory What am I doing wrong? I have tried many variations on the path to create the file with the same failure. Please help. My Command was almost correct. I had to rewrite the of section. The dev and disk location don't belong there.

HOW TO FIX: Force a hard drive to unmount for formatting on Mac OS

The dev in the if section is copy the device. The of section is a guide to where. If you cannot cd there you cannot copy to there. The corrected version that worked for me. OK so I actually got the whole thing to work and create a volume. Now it is telling me that there is no mountable volume. Am I just done and there is nothing left that can be preformed? I, too, and having trouble getting the drive attached. It was my boot disk, now it is invisible. It is spinning, but not seen.

Cannot boot into single user or target mode, won't be seen as an external drive either. You are all talking about drives that are visible to the system. Is it possible to make this happen or force attachment or mounting? If so, please tell someone who is not afraid of using terminal, but doesn't really know much about UNIX. Techtools, DW, Mount Me, etc. It is as if the drive simply isn't there.

I could swap the board with an identical drive but someone suggested that if the drive is spinning, this won't help. Is there any hope for me copying this drive? Sometimes even the dd Command fails to recover data from the dead Hard Drive at that time What should we do? Is my disk doomed? I only want the contents of two folders the downloads folder and the logic folder in the music folder. Is there any quick way into these?

Very difficult to diagnose dead hard drive, if the OS has corrupted then you can access your data with help of another working pc and copy all data in another drive. For more information: Thanks, this is the best tool on restoring a busted drive! I thought I would also share one hint I discovered. I ended up in a situation when I needed to restore an external USB harddrive, and I only had a spare harddrive of the same disk capacity M. So, making a disk image of the failed drive on a new drive crashed after 2 days of dd-ing with 'no disk space left on device' error. So, instead of running to get a larger-capacity USB drive, I figured out I can compress a new image with 'sparse' option, so it will fit on the available drive of the same size: Lost your password?

Recover a dead hard drive using dd Mar 04, '05 The Unix program dd is a disk copying util that you can use at the command line in order to make a disk image. It makes a bit-by-bit copy of the drive it's copying, caring nothing about filesystem type, files, or anything else. It's a great way to workaround the need for Norton Ghost. Normally, in order to make a disk image, the disk you're copying from has to be able to spin up and talk -- in other words, it's OK to make a copy if the disk is healthy.

But what happens when your disk is becoming a doorstop? As long as it continues to spin, even with physical damage on the drive, dd and Mac OS X will get you out of the fire. We had a situation recently where a friend sent a disk to us that had hard physical errors on it. It would boot in Windows, but then it would hit one of these scratch marks and just die.

We fired up dd , and it started OK, but stopped at the same physical error location -- complaining about a Hard Error. So the workaround was to designate the dd mode as noerror -- which just slides over the hard stops, and to add the mode sync , which fills the image with nulls at that point. We did it on BSD Unix, but as long as you can get the hard drive attached to your Mac, the command is the same: Since dd doesn't care about the contents of the drive, it copies every bit on the thing, so you get an image equal to the disk's capacity.

A really big file. One workaround is to put it on a RAID array. Once you've established the disk image in this example, foo. Here's where your Mac OS X box is far and away the best thing to have. In this example, the dd output file is foo. You have to realize that this is an exact copy of a busted drive, but the "holes" are filled with nulls. As long as the damage isn't to the boot sector, though, when you double-click on it, Mac OS X mounts it without breathing hard Due to the size of the image that we were copying, we put it on a RAID array, and had to access the image over the network -- it still mounted fine.

In straight UNIX, if you try to mount a disk image, it complains that there is "no block device" and fails. Once your image is mounted, it appears in your Finder, and then it's easy work to retrieve the critical files from the image -- usually things like. Finally, since your disk is actually dying, once you have your image, you can drop it to tape or something and you've not only recovered your files, you've made a viable backup as well.

Recover a dead hard drive using dd Authored by: This is the best hint I have ever seen. Thank you.

I so agree!!! Thanks in advance for any help you can offer, Stephen [ Reply to This ]. Superboy on Jul 24, '06 In OS X you can use the "disktool" command to find out what disks you have connected. Try disktool -l to get started. I don't know how you would do this on other Unixes - it varies by system, as does the disk naming convention. It depends on what OS you're trying to read the disk in, really. See your sig for details. I can't tell you the exact location of the unmounted drive.

What's the difference, which one should be used? SliqLinux on Apr 01, '05 Thanks in advance, Jeff [ Reply to This ]. This is the mount point of your volume where its files can be accessed , but is not the device file.

Use the command 'df' to see where Jeff is mounted. It should be something like disk1s3 or something. It will most likely be something different.
