Using diskwarrior mac1/2/2024 ![]() ![]() Once booted in the Recovery Partition, you have to go the menu 'Utilities', start the Terminal and launch DW from there (/Volumes/DW/go). Method one cannot rebuild the boot drive, method (2) and (3) require another already existing bootable volume and method (4) uses the Recovery Partition. ![]() Which contains a valid operating system installationĤ) Launch DiskWarrior from the OS X Recovery Disk To utilize DiskWarrior to rebuild the directory of a disk, you can:ġ) Install DiskWarrior to the computer’s main hard driveĢ) Install DiskWarrior to a secondary/external drive or USB Flash device, The Four Methods for Utilizing the Software. The answer to Suby's question is that with the recent version of DiskWarrior (5.x), the 'medium' provided by Alsoft (USB stick instead of CD/DVD) is no longer used as a boot volume but as a volume mounted while booted into the Recovery Partition. It's the alt/option key, not the control key (which Suby corrected in his second post). Presumably a volume needs to contain a version of Mac OS X that is recent enough to be compatible with the Mac to be shown on the menu. It lets you pick a volume to start from while the computer is starting up. Spend the money on backup drives instead.What is pressing control during boot supposed to do? Don't waste money on it or anything like it. If you don't back up, you'll eventually lose all your data, and Disk Warrior won't be able to save you. If you have adequate backups-which means multiple backups-you’ll never need a recovery tool, and therefore Disk Warrior is useless to you. No third-party software is needed for that.ĭisk Warrior is not a maintenance tool it's a recovery tool. Nevertheless, if you have reasons of your own to believe that rebuilding a directory is a useful maintenance step-rather than pointless busywork-you can do it faster and more safely by erasing the volume and restoring from a backup. ![]() Whenever I've asked DW advocates to substantiate their belief in its value, the response has always been along the lines of, "Because I say so," or "Because X says so." But every time I check, X either never made the statement, or else he has no data to support it. There has never been any evidence, as far as I know, to support that belief, and the last time I checked, the developer of Disk Warrior was no longer making such a claim on its website. There may still be some people who believe that rebuilding a volume directory improves performance. Occasionally the fault might be in another internal component, or in an external drive enclosure, rather than in the drive mechanism itself. Even if you choose to take the risk of continuing to use the drive after the first such incident, after any repetition the drive should be wiped and recycled, not restored. Any drive that malfunctions in that way should preferably be replaced at once. It is not caused by forced shutdowns or system crashes. The kind of directory corruption that you might need Disk Warrior to recover from can, for all practical purposes, only happen because of a hardware malfunction. Not having one is a mistake you shouldn't make more than once. That's assuming you have a working backup, of course. What it does-recreating a volume directory-can be done better and faster for free by erasing the volume and restoring from a backup. Otherwise, Disk Warrior is a waste of money. The only reason to buy your own copy is that you can't get to an Apple Store, or (like Apple) you provide help-desk services to other Mac users who don't back up their data. ![]() If you're in that position, then instead of spending about $100 on software that you should never need again, make a "Genius" appointment at an Apple Store, where the program is available for the "Geniuses" to use on customers' machines at no charge. Disk Warrior is an expensive and specialized application whose only use is to try to recover data from a damaged volume that Disk Utility can't repair, and for which there are no backups. ![]()
