Disk Warrior non booting drive

[pcpete]

We had a mac come in with a non booting drive. We made a clone with about 300,000 unread sectors. We have recovered the data using rstudio. We would like to get it booting without clean loading it. The clone we created is still not bootable and the OS X and disk utility will not fix its damaged file structure.

Is it worth buying Disk Warrior as a way of repairing the file structure as a way of making it bootable? If that what it mainly does or does it do more like a data recovery process like rstudio?

If we have a program like rstudio, is Disk Warrior worth buying for other types of repairs(for future jobs)

Replying where I probably shouldn't be replying, (I'm not a Mac person).............LOL!

I wouldn't rely on a "clone" that had 300,000 unread sectors.......Mac, Windows, Linux, or any others.
Just sounds like issues down the road, unless Disk Warrior is REALLY good at this kind of issue.

Again, just my point of view.......I'm sure some more knowledgeable Mac people will post.

Which files are affected by the 300,000 unread sectors?

not sure.

not sure.

What did you use to clone the drive?

it is about 150MB, which is significant and probably to damaged to try and clone. Even if this job is not feasible, I would consider buying "Disk Warrior" for future jobs.

edited: we ordered it and we will see what happens.

What is the point of what you're trying to do? Reuse the drive? Do a clone/ migration? Pull files?

Disk Warrior will do a better job of rebuilding the index than Disk Utility, and has a better chance of making the disk bootable, but you are left with a highly questionable drive.

For all types of file systems, I recommend DDRescue if you're not going to farm out the job to the pro's. I prefer to use Ubuntu and do a drive to drive copy. At this point, Ubuntu has a HFS repair tool (https://abhinay.wordpress.com/2009/04/12/repair-fix-mac-hfs-partition-using-ubuntu-cd/) and it MIGHT fix your issue. I've only done this on external HDD's formatted with HFS, but it should work for any drive partitioned with HFS/HFS+.

The kosher method is to reload the OS, but in a pinch this might get you by.

I would purchase Disk Warrior just to have it on hand, I've used it many times now and it pays for itself on the first use. I can't say it will do what you are looking for though, just a good program.

I would just re-install whatever version of OS X they have on to the drive it was cloned to. With that much missing stuff there is no telling what is is missing. And I guess there was no Time Machine backups?

Sounds like a job for SUPER MAC GUY!

We already recovered the data if needed. If possible it would have been nice to make the clone bootable with the hopes of saving the clients configuration and programs. With 150mb missing, it may not work out the best even with a repair install.

Yes, DW is good to have in your toolbox. You should just run it on the clone to see what it can do. If it can "fix" and "rebuild" the drive, do it. Then see if drive appears in "Startup Disk" preferences. If so, rather than use it to boot computer again, you can use Migration Assistant on it to move the User data and Applications to a freshly installed (100% working) OS. Make sense?

 

[altrenda]

If you've recovered the data and cloned to a healthy drive, why not give DiskWarrior a shot? What have you got to lose?
I take it the clone won't boot into recovery mode either.

DiskWarrior is worth having if you work on Macs. I also use TechTool, which can rebuild the index as well, but I prefer DiskWarrior. They both can come in handy and do different things.

And as said above, a fresh install and migration is the best end solution.

I would use Disk Warrior to rebuild the clone or dmg file only. This may help it mount properly so Migration Assistant has a good shot of pulling programs and user profiles over. Of course, even this advice comes with a grain of salt because if the file structure corruption was too bad, then Diskwarrior will take a data recovery software approach and drop much of the recovered raw data in to a "rescued items" folder. So, after Diskwarrior has built the directory make sure you "preview" it to make sure this isn't the result before the replacement because there will be no turning back except to start over again. However, I would still load a clean system and transfer from the rebuilt clone. Disk Warrior is fantastic software and very powerful. But understanding how, where and when to utilize it is key.
