I encountered two additional, but easily resolvable, issues. It took me longer than I care to admit to realize I had forgotten to include the forward slash before Volumes. It's important that to enter that command exactly: add a space or lose a slash and DiskWarrior won't launch. You must boot into the Recovery partition (you hold down the R key), launch the Terminal (from the Utilities menu), and enter a command into the prompt (/Volumes/DW/go). ![]() Since Apple released its Recovery partition (with OS X 10.7), the process has become more complicated. ![]() (You can also create your own using a 2GB flash drive.) If your system is running OS 10.6 or earlier (preinstalled on Macs prior to 2011), you can boot directly off the drive by holding down the Option key. Now that Apple has largely jettisoned disk drives, Alsoft ships the utility on a flash drive. If a disk is mechanically failing, DiskWarrior lets you repair your Mac's directory and back up its data before you replace the drive. Repairing a directory can make files and partitions reappear, improve performance, and even recoup disk space. Given that a directory contains millions of data points, the process is simpler in theory than practice. Unlike other utilities that attempt to repair problems in the existing directory, DiskWarrior creates a new directory. DiskWarrior rebuilds that file system using existing data. Defective RAM, power glitches, and poorly-written software can throw that table of contents into disorder.Īs a senior Alsoft technician explained it, Apple's file system (HFS+) is a complicated animal. DiskWarrior is designed to scan, maintain, and repair the directory, which you can think of as a table of contents. In the current version, the method has changed, but not the aim. Reviewing a previous version of the utility, we described DiskWarrior as almost singularly focused on rebuilding damaged directories. While Prosoft Data Rescue 4 ($99.00 at Prosoft) can scan disks to recover lost or deleted files, DiskWarrior is unrivaled in its ability to repair and rebuild the Mac directory. That includes utilities from Apple, whose Disk Utility may be suitable for basic maintenance and partition, but remains ill-prepared to repair badly damaged directories that result in kernel panics and boot failures. While Alsoft has updated the utility and adopted flash storage over the past 18 years, DiskWarrior continues to perform maintenance and recovery tasks that no other utility can do. I've been using the $119 DiskWarrior to perform routine maintenance and to resurrect defunct Macs since it shipped on a CD. In fact, Alsoft DiskWarrior is one of the best utilities you can buy for your Mac. Today, the utility is no less useful for a swivel-neck iMac or a MacBook with a solid-state drive (SSD). In fact, that isn't entirely true: Apple once bundled the third-party utility with AppleCare. Best Malware Removal and Protection SoftwareĪlsoft DiskWarrior is the data recovery software that Apple forgot to include. ![]() If anyone can recommend one with a Firewire 800 interface, or an inexpensive Thunderbolt one, that would be appreciated. Most of them are USB, and very, very few (and expensive) have a Thunderbolt interface. I am starting to look at purchasing a 512 gig SSD (preferably a Samsung 850 Pro, although an 850 EVIO would be OK), but I cannot find a slim, 2.5″ external case with a Firewire 800 interface. Both of the Seagate drives spin at 7200 rpm, and the connection to the Mini is via Firewire 800, and for the Air, it is Thunderbolt-to-Firewire 800. Like Carbon Copy Cloner, I can boot either Mac from their respective SuperDuper! backup, but it takes longer than 30 seconds. I also have v4 of Disk Warrior, and I do run it once in a while.įor my SSDs, as I’m sure most folks know, Volume Optimization does not apply, and thus I only need to use the File Optimization feature of TechTool Pro. That combination (along with my daily cleaning up) works very, very well. For my disk cleanup/maintenance/repair and backup tasks (once a week), I use Onyx, TechTool Pro V8.0.3, and SuperDuper!. And, I have two Seagate 1 TB external drives I use for 1) backups, and 2) storing large files/folders. Both of my Macs (a late 2012 Core i7 Mac Mini, and a mid 2013 13″ MacBook Air) have SSDs inside (256 gig Samsung 840 Pro in the mini, and (I believe) a 251 gig Samsung 840 EVO in the Air).
