I have one hard drive connected to my iMac for use with Time Machine. In addition to the Time Machine backup, I maintain a bootable clone of my iMac's hard drive using SuperDuper. The hard drive with the bootable backup is stored at my in-laws' house (you could just as easily store it at a friend's house or at work). The off-site clone is updated once a ...

On Snow Leopard, you would need to boot from an external OS to wipe the drive. On Mountain Lion (or Lion), the system makes a recovery HD so you can self-wipe the Mac. This is a much, much faster and easier task, so I recommend you upgrade first and then do the wiping using a recovery boot and Disk Utility. I personally would do these steps (and you could ...

I would try using rsync from the command line. rsync -av --ignore-errors /Volumes/failingDrive/ /Volumes/brandNewDrive should do the trick. Mind the trailing / at the end of the source. Rsync will not copy files it finds on the destination, so if you call it a second time it will continue where it left off.

First step, use a low level tool like dd to make an image of the drive as it exists now, and then stop using the drive. Every second that drive spends connected to a computer (especially a Mac) is a chance for something new to be written to it on top of data you want to recover. All of your recovery attempts should be performed on the image that you make. ...

From the Apple Support pages Securely erasing a disk To securely erase a disk or partition: In Disk Utility, select the disk or partition to erase, and then click Erase. Specify a format, and enter a name for the disk. Click Security Options and choose to write over the data once, 7 times, or 35 times. Click OK. Click Erase. Writing ...

As current hard drive-oriented techniques for file sanitization are ineffective on SSDs, I recommend to encrypt the whole hard drive using Filevault 2 (best if you did this before you put your data onto it). (This is only possible in Lion, Filevault 1 in older versions of MacOS will only encrypt your home folder.) This way you will not erase your data, but ...

rsync (from Terminal) has an option for that (--ignore-errors). However crafting the right command line arguments may be somewhat complicated. A nice rsync GUI is Carbon Copy Cloner (donationware) After you are satisfied with the cloning setting, launch clone in CCC and immediately after run from terminal ps axuww| grep rsync and you will see the right ...

You do not like the cloud - yet, I will suggest online backup solutions for a worst-case-scenario, because I believe that they're the most reliable. better data retention and preservation, after all your hard disk is prone to data loss since it's a magnetic device online backups are not prone to house robbery since they are stored in a different location ...

Absolutely! I plan for the worse! As a first level of defence I'm running Time Machine against all my important files. Photos and videos. Things I wouldn't want to lose. This gives me some "stupidity insurance" -- if I delete something accidentally, hopefully I can get it back from a Time Machine snapshot. I also push all my data out to the cloud. I'm a ...

While I never tried it myself, in theory you could use something like PhoneDisk to open the app's private folder and copy all the content to your computer. Then, after deleting and reinstalling the app, you should be able to copy the content back.

HFS Plus (HFS+) is a fragile and a little outdated filesystem. If you google it, you'll find many reports of filesystem corruption. Rebooting without unmounting the filesystem is the best way to corrupt it. This happens when the mac freezes for some reason (in my case it's the nvidia video card) or power failures. Here are some tips, that IMHO should lower ...

You can use the terminal to do this. The following command should work: find /path/to/the/folder \ -name "*.jpg" \ -exec bash -c "sips -g pixelHeight -g pixelWidth {} | grep -E ' [12]?[0-9]{0,2}$' >/dev/null" \;\ -print That command will find all JPEG files under /path/to/the/folder which have a width or a height of between 1 and 299 pixels. ...

There is little hope unless one or both of the editors squirrel away copies of the file for you or embed the undo buffer in the document. It really depends on the editors and the settings. One last ditch effort is to use the mdfind command. If that file had a memorable string or misspelling you could see in an instant if any files on the disk contain that ...

Which iPhone OS and model do you have? The newer ones encrypt the data and the erase deletes the key. The chances of DIY recovery are slim. If you pull it off, you probably can get hired for iPhone forensics and make some serious salary doing that professionally. Older devices are more amenable to typical recovery efforts. Either way you will need a ...

SSDs don't come in an 80GB size (that I've seen -- usually multiples of 32GB). It may be possible depending on why the drive dies. If its a mechanical failure, then you could take the drive to a specialty computer repair shop (try local before the big stores), and they should be able to help you with diagnosing the actual issue. Since the data is stored ...

If you are comfortable using the command line, you could use dd to copy your drive byte-for-byte. First, you need to find the BSD identifier for your internal drive. If you are booted from the drive, this will be disk0. Otherwise, it is most likely disk1, but you should run the following command to see all of your disks and the partitions they contain. ...

You might try using Target Disk Mode - hold down T at startup and then connect the MacBook Pro to another Mac (or a PC that can read Mac drives) via FireWire or Thunderbolt. Or try holding down the Shift key to boot into Safe Boot mode. If neither of those work, try booting from your MacBook Pro's system restore DVD, use Disk Utility and try repairing the ...

Photos are not stored on a particular sector on your hard drive, the sectors are maintained by the operating system and the hard drive itself. I would suggest scanning the entire drive for deleted files as your best chance of finding the files you are looking for.

If you backup with iTunes and you restored from the backup and the notes were gone, then there is no where to retrieve them from unless you have another backup that contains those notes. Launch iTunes on the computer and go to iTunes>Preferences>Devices. You will see a window with all of your backups listed in it. If you see a recent backup that you are ...

I use cp -Rfv sourcefile destinationfile with success on a pretty regular basis. cp = copy R = maintains file hierarchies f = if an existing destination file cannot be opened, remove it and try again v = verbose mode, displays files transferred as it progresses sourcefile = data you want to copy destinationfile = directory/drive you want to copy to

Data Rescue is a long time favorite for undeleting files. It is not free, but you can download a free trial to see if the folder and files can be recreated before deciding to pay for the software or seeking professional recovery. Similar to Windows, OS X doesn't wipe the files but instead marks the directory entries as free. As long as the files do not get ...

The only sure way is to restore from your latest backup, which is why Apple added Time Machine for easy use. If you do not have that then the first thing to do is turn the machine off so that no more data is written to the disk. Then boot the machine off a recovery disk like Diskwarrior. If you are lucky then you can restore data if not the next step would ...

You could try following this hint from Macworld. It makes use of the Terminal (0$) to execute the UNIX command dd to copy everything bit-by-bit from your harddrive to another location. 1. Determine UNIX id. of dead drive If you decide to use this method you would first have to determine what the UNIX identifier of the attached disk is. Open up Terminal ...

I found how to make iTunes restore only contacts, while preserving the rest intact: run iTunes before connecting iPhone disable auto-syncing in preferences: Edit > Preferences > Devices > Prevent iPods, iPhones, and iPads from syncing automatically should be switched On connect iPhone to PC.

You do know that RAID 0 is only striping and not only provides no redundancy, but increases the risk of data loss as the failure of any single drive can mean the loss of the entire storage pool? RAID 0 is only for increasing read and write speeds, for example for video editing. You need at least RAID 1 or 5 for redundancy. That being said, if you're losing ...

If you quit TextEdit, then reopening TextEdit will re-open all your documents. If it didn't give you an option to save, then they were stored by Restore in the Saved Application State. When you next open the app, they should have been there as the application state is restored. If this did not occur, then something else went wrong and the application state ...

The Apple installer does not erase the disk unless you tell it to - that involves opening Disk Utility. So your files are fairly likely to still be there in the Users folder, just under your old user name. However, you said "She used the installation CD" - you have old hardware running OS X.6 (Snow Leopard) or earlier? those versions DID have an "erase and ...

Use the drive as little as possible. Plug it into an enclosure or simply boot the machine in TDM mode and connect it to another machine. Pull over only the files you need (to minimize the time you spend accessing the drive). You may want to do something like, just your ~/Desktop, ~/Documents, ~/Pictures, ~/Library/Mail, and ~/Library/Mail Downloads. Do ...
