![]() If only one line appears (no indented volume info), then the drive's partition map is damaged. In this instance a data recovery company is likely your only option. If Disk Utility does not see the drive then there likely is a hardware failure. This may also give you the format of the drive.ĭiskWarrior 5.x does not repair an APFS formatted drive.įor all publicly available information regarding DiskWarrior 5 and macOS 10.13 (High Sierra), 10.14 (Mojave), 10.15 (Catalina) as well as the new Apple File System (APFS), please visit DiskWarrior and High Sierra/Mojave/Catalina In the window that opens there will be a line "File System". If the format is blank, click on the Info button at the top of Disk Utility. However, if the drive reads as PC Exchange, ExFAT, FAT16 or FAT32, NTFS (and more) then the disk is PC formatted and you will need to recover your data using a Windows-based utility while the drive is connected under a Windows operating system. If the drive meets the formatting requirements listed above, DiskWarrior will work to rebuild the directory of the drive. At the bottom of the screen you should see the line "Format". Instead you may see "untitled" or "disk1s2" (your specific numbers will vary). This may not be the recognizable name of your drive. The second line should be indented and have a volume name. The first line should state the manufacturer of the drive (LaCie/G-Drive/etc) and the size in gigabytes (GB) or terabytes (TB). Your drive should appear with two lines of data: To double-check that the directory of the hard drive is readable by DiskWarrior in its current state, please open the Apple Disk Utility (located in any computer's Utilities folder or on the Apple Install CD/DVD under the Utilities menu or via the Recovery HD in Mac OS X 10.7.x Lion and later). Did you reformat this drive when you first used it or did you use the drive as is? Macs can read from and write to a variety of disk formats and many external disks come PC formatted from the factory. Best of luck, we've all been there.DiskWarrior 5 will attempt to rebuild the directory of a hard drive as long as it is formatted using the format of Mac OS Standard, Mac OS Extended, Mac OS Extended (Journaled) or Mac OS Extended (case-sensitive). It IS possible to do so and mount the disc without a clean room, it is just very very difficult and not likely to work due to contamination, the massive power of the magnets inside hard drives touching the platters, etc. If that doesn't work send it off to professionals or if you are incredibly brave and very poor, get an identical drive and take both apart, replace the platters and immediately create a disc image because that is about how long it will continue working. Otherwise try my first suggestions and if absolutely nothing works and you are ready to write the whole thing off and about to throw it away whack it two or three times laterally as hard as you would smack a bee that stuck you but no harder. Try Disk warrior first and if none work, try mounting the disk again and again in Disk Utility - sometimes it will suddenly come to life for a little while. You might consider all the common data recovery programs or dd_rescue. Apple users have long used Disk Warrior to fix non-mounting drives - in fact, if you can get a hard drive to mount long enough to create a virtual copy Disk Warrior will repair the image itself.įinally, as the poster above mentioned, there are data recovery companies that will recover the data pretty much no matter what if the platters are intact but they are shockingly expensive. Some people have had success with hard drives that still spin but won't mount by cooling them down with aerosol coolant or refrigeration (in a completely dry rice or silica gel filled container) and then plugging back in and if they mount, quickly creating a virtual image of the drive.Īnother trick is to replace the hard drive's printed circuit board with the one from a working identical drive and quickly create an image. If your HD still has some life you could try a few tricks:
