Alsoft releases DiskWarrior 4 (Universal Binary)

Alsoft today released DiskWarrior 4.

DiskWarrior 4 maintains, repairs, and recovers Mac disks on both PowerPC and Intel-based Macs as the application is now a Universal Binary.

DiskWarrior 4 costs US$99.95 for the full version and $49.95 for the upgrade.

More info:


  1. Disk Warrior is the premium “Disk Repair” Utility ….

    If it can’t fix what’s ailing your drive ….you’ll have to bring your machine into the shop ..

    It has saved me from doing that at least 4 times

    Also … it will warn you if your drive is about to fail …. Run it about twice a year on its own for absolutely worry and trouble free computing.

    Worth its weight in gold ….

    Solve a myriad of problems …. gives you a brand spanking new directory.

  2. Actually, version 3.0 and later do not include the defrag utility. The previous Mac OS 9 (and earlier) version included a defrag utility call Plus Optimizer. The one situation where a defrag utility is still helpful under Mac OS X is if your boot drive (or volume) is unusually small (as in less than 10 GBs). Then, your free space will be only a few GBs, and the drive can get quite fragmented because the OS uses that free space for its virtual memory swap file.

    This is good timing; just in time for MacWorld San Francisco. I bought my version 3 upgrade at MacWorld for a discount, and I’ll probably do it again next month.

  3. I ran a 30-Mac computer lab for nine years, until June 2006.

    Diskwarrior repaired more computers than any other utility, by a factor of ten. One out of forty times or so, DiskWarrior could not recover a Mac that another utility did. If you can only afford one repair utility, and now that I’m no longer maintaining a whole lab, get DiskWarrior.

    DiskWarrior also saved the stuff on my own personal Macs several times over the years. I have ordered my update already.

  4. IMHO disk warrior was without equal for OS9…back in the day, it displayed almost supernatural abilities to boost performance and bring back suposedly dead machines from beyond the grave. It paid for itself dozens of times over; saving important data and expensive machines for my organization more times than I can count. Back then I recomended it to all mac owners. Honestly, I have found the OSX version to be a bit less reliable and not quite as likely to “save the day when all else fails”. I have had several experiences with it looking at various bad HDs for (what feels like) forever and then just giving up and saying it can’t fix it, even if the drive is actually still working. The OSX versions I have used also seem a bit picky and tempermental about which specific mac models they can successfully boot. My final complaint is that my cheap ass is a bit annoyed by always having to pay for new versions. Nonethless, the consensus amongst the Mac techies I know is that it is still the best (if not the only) mac utility to invest your money in, just don’t expect the same miracles that you might read about in old archived forums from a few years back.
