Diskwarrior 5.1 (Mac)

I made the mistake of running Time Machine backups on a network drive (not really a good idea), and the network drive was a Time Capsule (REALLY BAD IDEA!); so when a failed upgrade to MacOS Sierra bricked my Macbook Air, I found to my horror that the Time Machine backup was empty, even though the Time Capsule reported that it contained a large amount of data. A knowledgeable friend recommended DW as the best chance of recovering the important data. I gulped at the price; but having no option, I bought a copy. None too confident, I installed and ran the software on an iMac, and pointed it at the damaged Time Machine sparsebundle... Now, remember that DW is really designed for fixing damaged directories on directly connected (i.e internal or USB/firewire/etc external) drives that are formatted as MacOS Extended (Journalled), so my chances seemed slim for fixing a sparsebundle on an AFP-formatted network drive (which is what Time Capsules are). (Note to self: in future, only ever use USB drives, formated as MacOS Extended (Journalled) for Time Machine backups!) I waited with mounting anxiety for DW to 'rebuild' the damaged sparsebundle. It seemed to take forever - but then the Time Capsule is a massive 2Tb, and it was almost full of Time Machine data... At last, after what felt like an eternity (but was probably only about 10 minutes), DiskWarrior reported it had successfully rebuilt the directories and recovered all the files! At this point, DW does not write anything back on to the drive: rather, it shows you a 'Preview' of the directories and files it will restore. This allows you to see whether some of the data is still damaged, and decide that you need to try some other method of getting it back before DW makes that difficult or impossible by writing the faulty versions back on to your drive. But the completely genius bit is that DW lets you copy recovered directories and files from the Preview! Indeed, it recommends that you do this for important data. So I copied off all the stuff I needed, and tested it to see that it was OK. And this turned out to be a good idea, because when I told DW to rebuild the sparsebundle, and it started to do so, it threw an error to say it was unable to rebuild the 'drive' and that I should run the program again to have another go. I did, but got the same error again. And then I realised that the reason DW couldn't rebuild the drive was that the Time Machine sparsebundle was on a networked AFP-formatted Time Capsule drive, and that's NOT what DW is designed to fix. (I contacted the fast, helpful and friendly DW support team by email, and they confirmed that this is was, indeed, the problem.) In other words, DW has retrieved all my data, even though I was asking it to rebuild a type of drive it wasn't really designed for. How's that for awesome? So if, like me, you gulp when you see the price of this package, buy it anyway: it is very probably the best tool you'll ever own for rebuilding damaged directories on a Mac. (And I haven't even mentioned that it comes on a bootable USB drive, that you can plug in and use to rebuild a damaged main hard disk on a Mac that won't even boot, using the Mac's 'recovery boot mode'.) Just buy it!

Software didn't do the job at all. Getting tons of error codes but no actual results. Fair enough, contacted their support and no response after 3 days at all. The software is still basic and there are free opensource solutions available that offer more in dept changes. With Disk Warrior you press a button and it either fixes it or throws errors at you like disk manager.

I like it. It works for hard drive repair.

Although this version of Disk Warrior doesn’t work fully with the latest versions of Mac OS they are working on this and it works brilliantly with earlier iterations I’ve used it in the past to start up seemingly unresponsive iMacs and just used it to repair the directory on an external 4TB drive that wouldn’t mount after a power cut. It took about 10 minutes. Expensive but worth every penny!

Within a week the problems with my Macbook had gone from annoying to critical. It started with the beach ball turning round and round a few times a day until finally it was impossible to get beyond logging on. The disk utility failed to exterminate the problem and it looked as if my two year old Mac was dead. At this point it's important to remember that one should back up the hard disk regularly. Disk warrior took only five minutes to resolve the problem.

It gets as far as allowing me to choose the green drive icon then goes away on holiday. Refund time.

Costs a fortune, but worth every penny. I had a dodgy external SSD which neither Disk Utility nor Paragon Hard Disk Manager could do anything for. Not life & death, but a blooming nuisance to lose a bunch of files. Tried the only genuinely free solution I could find, and it didn't work either. Shelled out for this, received it the same day, installed it - it found my disk automatically, restored the files and rebuilt the file system - no need to wipe, set up partitions and start again. Shows you get what you pay for, IMHO - a very happy customer.

I found DiskWarrior after looking for a way to sort out a corrupted file system on an attached Firewire Drobo array used for Time Machine backups of several computers. Before finding the software it did seem as though I would have replace or at least reformat some disks in the array as the builtin macOS Disk Utility program was unable to fix the issue. I understand that this software is recommended by Data Robotics to support their own range of Drobo products. The software can be run directly from a USB drive if you follow the instructions In my case the problem was with an external disk array so I installed it directly onto the Mac boot disk to make use of the maximum amount of memory. The software takes a while to scan and analyse a file system (the time being dependent upon the size and complexity of the file system). Once the scan has been completed it provides a report on the state of the file system and the option to rewrite the directory structure (and thus resolve the problems). So far on the few occasions I have had to run it the repair has been successful.

So here's the story... I had a Iomega passport external hard drive that I used as a time machine backup maybe 5 years ago, and I kept meaning to back it up to a new external HD with it's own power source (because those are more reliable). I had heard from a few people that their HD had crashed and I thought well maybe they had done something stupid like not eject the disk before unplugging it or had tons of questionable material on the drive to begin with. Whatever the case maybe, I thought it's never going to happen to me. Anyway I finally remembered and learned how to back up a old time machine backup from an old drive to a new drive this week and got that old drive out. I remembered taking something off the drive last year and everything was fine so I figured no problem. And then it happened! I had gotten an error that I have never seen before! "OS X can't repair the disk 'My name Backup' you can still open or copy files on the disk, but you can't save changes to files on the disk. Back up the disk and reformat it as soon as you can". I thought "oh crap". Well at least the error said I could copy the files but ... it turned out that I couldn't! I only saw Backups.backupdb folder that was empty even though the drive was full! I thought I can fix this I am have watched enough youtube videos on computers to feel geeky. I opened terminal thinking I could find a back door solution, I couldn't. I opened Mac utilities to run first aid and see if it would repair permissions, no luck, instead I got an error that said invalid number of keys. And I thought to myself well if you know there there is the wrong number of keys then just fix it! Anyway I was going to give up on the drive because I was pretty sure that I had backed up all the important files to some other drive but I still had my doubts. I had heard of disk warrior but again I never thought I would need it so didn't no much about it. I went to the website and I was even more disappointed because it looked like they had not updated the site since the 90's, so I felt that maybe the company had gone out of business or something and I was worried that I was going to by some really antiquated software even though it said that is supported El Capitan (OS X 10.11). So I did what everyone does and looked at amazon reviews and looked at the 1 and 2 stars to see why people hated it and the comments did scare me a little but I thought that maybe their problem was not the same as mine and software can only do what it is programed to do, it doesn't fix the worlds problems. So even though it had some bad reviews out there, I was desperate, and I had never heard of some of the other recovery software for Macs like "data rescue" that were getting the equal number of stars as Disk Warrior. So although those might have been good alternative and slightly less expensive I didn't want to go a little cheaper and realize it didn't work because I wasn't going to buy another recovery software and waist more money on getting data that I wasn't sure was worth it. So I go the Disk Warrior USB stick today May 2016 and I installed it and it just worked! That Backups folder was no longer empty and I am copying the files from the old drive to a new one as I write this review. So in Summary 1) DiskWarrior's website may look old but the software isn't. 2) It worked by getting the files I needed when disk utility wouldn't help me out 3) Always back up your files, never have just one place with all your files

I got this to fix some SoftRAID configured external HDD's and it worked a treat for that, so money well spent. It would be nice to see a free upgrade that also handles Apple's newer APFS disks for total peace of mind.

Tous les avis lus sont crédibles. Sur de vieux DD extérieurs très (trop) utilisés il est clair qu'il y a des problèmes mécaniques...DiskWarrior répare ce qu'il peut lire (beaucoup si ce n'est tout, c'est clair !). À nous de les sauvegarder ensuite sur un bon disque. Les réparations éventuelles sont indiquées...à chaque réparation du même DD le nombre de problème NE DOIT PAS augmenter ce qui serait, je crois, un signe de fatigue mécanique. Cher, oui, mais incontournable ! Si on n'a qu'un DD interne... c'est FOLIE de s'en passer ! Il est aussi sur une clé USB (pas encore utilisée). fadu

This has saved my files more than once. It's worth its weight in gold.

Fidèle utilisateur de cette application depuis plusieurs années , je n'ai jamais été déçu et continue donc avec cette version pour os high sierra . DISKWARRIOR est efficace et facile d'utilisation . Je recommande à qui ne veut pas rester bêtement le bec dans l'eau en raison de connaissances insuffisantes en informatique . Produit bien emballé et mode d'emploi clair en anglais , mais de nombreuses explications en français sur internet .
