![]() ![]() 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. You have to realize that this is an exact copy of a busted drive, but the "holes" are filled with nulls. In this example, the dd output file is foo.dmg. Here's where your Mac OS X box is far and away the best thing to have. Once you've established the disk image (in this example, foo.dmg), you're almost home. One workaround is to put it on a RAID array. 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. Make sure that the chosen directory ( some_dir) has enough room to take the entire disk image - which will be equal to the size of the drive. The bs=512 designates block size, and the if=/dev/rXX# is the UNIX path to the actual disk device. 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:ĭd bs=512 if=/dev/rXX# of=/some_dir/foo.dmg conv=noerror,sync 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 fired up dd, and it started OK, but stopped at the same physical error location - complaining about a Hard Error. It would boot in Windows, but then it would hit one of these scratch marks and just die. We had a situation recently where a friend sent a disk to us that had hard physical errors on it. 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. 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. It's a great way to workaround the need for Norton Ghost. It makes a bit-by-bit copy of the drive it's copying, caring nothing about filesystem type, files, or anything else. Filesalvage should be used on a regular basis to ensure that all of your computer's files are functioning properly this is particularly important if you use the internet for uploading or downloading files.The Unix program dd is a disk copying util that you can use at the command line in order to make a disk image. Once both repair and restore have been successfully performed, the file that is in the middle of the error will be replaced by a "new" file. In the fix option, the damaged files will be repaired and then restored to their previous state you will be given the opportunity to choose whether you want to undo the changes that have been made. You will then be able to open each file individually you will be able to see the location of the files and what type of problem they are suffering from. If you select the repairing option, you will receive a list of all the damaged files that the software has located on your system. Once the software has detected these files, you will be able to view them and choose which ones you wish to recover if you are unable to locate the files on your own, you can always utilize the help of the "restore" option that is present in the software.ĭepending on the scan options you selected during the installation, the software will give you two different recovery options: fixing the damaged files and restoring the files that were already lost. This will automatically begin a scan of your computer's hard drive to locate all lost, damaged and corrupted files. To repair a damaged drive, you need to have an operating system that is compatible with File Salamvage this will make the recovery process much faster as compared to trying to retrieve a file from an incompatible operating system.Īfter you download and install File Salamvage onto your computer, you just need to execute the program by clicking on the "scan" option that is found in the taskbar. One of the features that makes this tool unique is that it is capable of recovering corrupted, lost, empty and even reformatted files as well. File Salamvage does this by the process of intelligently collecting, compressing and then restoring the relevant information to your computer. Unlike other data recovery tools that require you to open the system, File Salemvage can open any version of the operating system, not matter if it is a PC, a Mac or even a Linux based Operating System. File Salemvage is the new kid on the market and it is a very efficient tool to use for data recovery. ![]()
