Using 500 gb WD Passport as both Time Machine Backup and Mac OS bootable HD

I just bought a 500 gb WD Passport to use as a Time Machine Backup HD with my MacBook Pro and was wondering if I could make it into a Mac OS bootable HD as well. I like having a backup HD and a recovery HD with me on the road and thought it would be great to have them in the same HD. One thought I had was to make two partitions on this HD: one for Time Machine and one for Recovery. Would that work? Is there a better way? Let me know your thoughts. Thank you.

One thing to consider is that certain WD external drive models do not work reliably as startup drives for Mac OS X, or at least for the latest versions of that OS. Before you get too far into this project, I suggest that you partition the drive (making sure that you use the GUID Partition Table partition scheme & HFS+ journaled volume scheme), install or clone Snow Leopard to one of the partitions to create your 'recovery' volume, & verify that your Mac will boot from it. If this works, you are good to go.
Obviously, you should not use this 'recovery' volume as your everyday startup drive or for data storage because as mentioned, if the WD drive fails, you would have no backup, but otherwise this is a good plan.
One little trick you might be interested in that I like for an external drive I use somewhat similarly: Normally, all the volumes on a drive will mount automatically when the drive is attached to a Mac, but it is sometimes handy if only the Time Machine one does this & the 'recovery' volume (or in my case a reference clone of my old Leopard installation) does not, which insures that this volume isn't accidentally disturbed by user error, is safe from any OS errors that might corrupt its files, doesn't tempt you to use it for normal data storage, & so on.
As it turns out, the OS provides an elegant method to do exactly that. As described in the Mac OS X Hints post "Prevent a given partition from mounting at boot" (which discusses doing this for essentially the same use as yours), you can create an "fstab" file in /private/etc/ that (among other things) can instruct the OS not to mount selected volumes automatically. This works perfectly with Leopard or Snow Leopard.
The really cool thing about this is that since the file is a part of the OS on the normal, everyday startup volume, it only has an effect if you start up from that volume. Thus, if say that volume is damaged & you can't start up from it, you don't have to do anything special to start up from the protected volume -- it appears in the Startup Manager's icons if you use the option key at startup time & even if you don't, if it is the only viable startup volume the Mac can find at boot time, it will start up from it automatically, after a brief delay.
If nothing else, check out the Hints post. It should reassure you that others do the same thing that you are considering.

Can Synology NAS serve both time machine backup and video/audio servers?

I'm looking for a NAS box such as Synology 2 bay solution. I've seen the box can be used as Samba server to store network folders and files; and also there is discussions on Mac Time Machine backup using the Synology boxes; I'm wonder if the RAID disks can be partitioned to do both, some space for the backup from time machine and others with regular NAS services as network disk space, and if you can share your experience if you have done that.

Your answer is found on the Synology website with this link:

Can you use the same external hard drive for Time Machine backups and as an additional storage drive?

I have an external HD that I've been using exclusively for Time Machine backups. I need to clear space on my hard drive, so I was thinking to move music & photos to an external drive. Wondering if I can use the same one I have (which I'll aslo keep using for Time Machine) or if I need to get another drive.

Hi Jossydtaylor,
Time Machine can use either an entire external disk or a partition of that disk:
OS X Mountain Lion: Disks you can use with Time Machine
http://support.apple.com/kb/PH11171
You can use Time Machine with a Time Capsule, and with USB, FireWire, and Thunderbolt disks. The backup disk can be directly connected to your computer or be on a network. If the backup disk has been divided into partitions, you can use one of the partitions.
If the disk is partitioned using the Master Boot Record (MBR) partition type, some partitions may not be available for use with Time Machine. The GUID Partition Table (GPT) partition type is recommended.
For more info on partitioning, see this article:

Can the time capsule be used as both a time machine backup and NAS storage

Can the time capsule be used as both a time machine backup and NAS storage? I want to use the drive as external, wireless storage for all of my files so all my PCs, MACs and iOS devices can access the files. Plus, I want to use the drive for backing up my iMac via time machine. Can the time capsule device be used for both these purposes simultaneously? If not, are the other suggestions on how I can do this?

Can the time capsule device be used for both these purposes simultaneously?
It can, but is really not recommended. Sooner or later there will be a fight for space on the drive between Time Machine and the other files.
If you have plenty of free space on the drive, you can do this......but.....have you thought about how you will back up the "other" files that are stored on the Time Capsule?

I get a 'No entry' Icon and a not supported on this type of Mac message. I cannot update either as anything up to 9.1.1 tells me I don't need it yet 9.1.2 tells me I need an eligable Logic Pro Version was not found in applications.
All of my files are stored in a separate hard drive with only the actual app having been on my Macbook. Should I just reinstall?

Hi
To run Mouitain Lion you need to update Logic.
For the updaters to work the Logic application must be:
a) Within the Applications folder, and not in any sub-folder
b) Named "Logic Pro" with no extra numbers or spaces

I would like to know if the TC can be used as a Time Machine backup device and for storage simultaneously?
for example:
Can I use 1TB for Time Machine backups and 1TB for storage.
Please let me know if this is possible?
Thank you

I tried for ages to seek a relatively easy way to do this.. i.e. partition it, it's a huge pain! You can, but i'm pretty savvy and got bored and confused! What I did do was switch the TM back-ups to manual so they don't end up filling the disk. Trust me it's the easiest and best option!

Is it possible to use an external hard drive for time machine backup and also as a regular hard drive?

I am using an external drive in the exact way that you described. You just keep it plugged in to the computer when you want to access the movies and files. In order to put files on it, just go to finder open up the drive under devices and drag and drop files onto the drive. It is just like using a usb drive with a terabyte of space.

The iPhoto library is a Time Machine backup, and so cannot be used as the main library. Reopen iPhoto with the Option key held down to choose another library.

I recently tried to look up my pictures on my time machine back up on an external hard drive. As soon as I try to open it I get the following message.
"The iPhoto library is a Time Machine backup, and so cannot be used as the main library. Reopen iPhoto with the Option key held down to choose another library."
I have tried holding down the option key but still couldn't few the photos.
I want to know if there is anyway I can actually view these photos. I have over 85gbs of photos on the hard drive. I have tried googling and looking at pervious forums with the same problem but nothing is working.
Please help!

Select Mac Help from the Finder's Help menu. Search for "Restore items backed up with Time Machine."

I cannot load Maverick on my iMac HD. It reports that my HD is used for Time Machine backups and will not load to that drive. I do not use this drive for backups. Help.

I cannot load Maverick on my iMac HD. It reports that my HD is used for Time Machine backups and will not load to that drive. I do not use this drive for backups. I use an external 1 TB WD My Book for backups as well as Super Duper Backups. Can anyone offer advice. Thanks.

Welcome to Apple Support Communities
You have got the "Backups.backupdb" folder in the root level of your hard drive. This is the folder used by Time Machine to save backups to, and the OS X Mavericks installer thought that your hard drive is being used to store Time Machine backups
To fix this, open a Finder window, select the Go menu (on the menu bar) > Go to Folder, and type:
Then, delete "Backups.backupdb" and empty the Trash. Finally, open the Mavericks installer from the Applications folder and follow the steps

Using a Time Capsule for Time Machine backups and as a data drive

Hi There....can I use my Apple Time Capsule for my Time Machine backups and as a drive I can put data on?

Yes, you can use your time capsule as a drive for data. If you create a disk image, you reserve a certain amount of space for that image. Time Machine will respect that space and leave the disk image alone even if there is a large amount of unused space on the image.
If you create a folder, it starts with zero space until you add data to it. The folder can be as large as you would like as long as the space is available on the TC.
So, each has an advantage. The disk image will reserve the space until you fill it up and the folder will not. But, the folder can be as large as you would like as long as the TC has space available.
Your next question might be can you change the size of a disk image after it has been created? I haven't tried this, but think you probably could.
For most users, I think the folder concept is probably simpler for them to use and easier to understand. But more advanced users may favor the disk image concept if they feel that space will be at a premium on the disk.

I used migration assn't to load a Time Machine backup onto a new mac. The first TM backup after that took some time, perhaps not surprising. But the backups thereafter have all taken hours, with huge amounts of "indexing" time. Time to reload TM?

Does every backup require lots of indexing? If so, the index may be damaged.
Try Repairing the backups, per #A5 in Time Machine - Troubleshooting.
If that doesn't help, see the pink box in #D2 of the same link.

Time Machine backup and main drive corrupted. Help! (REWARD OFFERED)

Here's the deal:
I have a Macbook Pro and a Mac Mini both runnign Snow Leopard. I use the Mac Mini as a kind of media center / server, it has a few external drives connected to it. On of these drives (1GB) is dedicated to Time Machine, the Mac Mini (80 GB hard drive) backs up to it directly and the Macbook Pro (500 GB hard drive) does it over the network (Time Machine created a sparsebundle). This has worked well for years now. Occasionally I got the error that Time Machine needed to start a new backup because the old one was corrupt. That happened about 2-3 times a year (did the same thing when I backued up via USB). Now about 2 weeks ago, that error came up and I just let the Macbook Pro on overnight and connected the ethernet cable for faster transfer.
When I woke up, the Macbook Pro didn't respont at all, spinning beachball, no response at all beside mouse movement. I let it do it's thing for another 10 hours (while I was at work) and just held down the power button to power off and restart it. But all I got was the gray-on-gray flashing folder with the question mark in it, that's what you get when the Mac can't find bootable partitions. So I popped in the OSX Snow Leopard install disk, ran disk utility. It saw the hard drive, but no partition (i.e. Machintosh HD) on it. I checked the Time Machine backup and the sparsebundle was 300 GB (the Macbook Pro had 400 GB used, the remaining 100 GB were free). There is no way to restore from an unfinished Time Machine backup...
First thing I did was clone the internal (Macbook Pro) hard drive to a DMG disk image using DiskDrill (the only program I found that could recognize the drive at all, not even DiskWarrior could). I also bought the exact same hard drive model and partitioned it like the cloned the corrupted hard drive to the new one using ddrescue (a command line tool that doesn't quit upon i/o errors but proceeds and tries to recover as much as it can). It copied everything except 65 kilobytes, the corrupted drive seemed to be physically damaged in a bunch of sectors relatively at the beginning of the disk. Since I had now an exact copy on a fresh, healthy drive, I went crazy trying out Disk Warrior (didn't recognize the drive at all), data rescue, testdisc, p a Windows isk, etc. Only R-Studio (on windows) showed the EFI and Macintosh HD partitions on there, they started and ended on the same sectors on the corrupted drive and its clone. After some research, I figured that the partition table was corrupt so I reformated the clone disk using the OSX Snow Leopard install disk (1 HFS Journaled Partition with GUID Partition table). R-Studio showed the EFI and Macintosh HD on that reformated drive, again, same sectors as before. So I figured I could just copy just the bytes where the Macintosh HD starts from the corrupted drive to the clone (using ddrescue). That worked, after almost 24 hours, I had the clone drive with a "disk1" partition on it that even disk utility could see.
Now I was able to run Disk Warrior on it, but all it could do was recover a few Application folders (Resource-Folders and lproj-stuff), about 100 MB in total. It couldn't repair more of catalog file apparently. Luckily, Time Machine backed up quite a bit (300 GB out of 400 GB of data) and I was able to manually copy all the Dokuments, Desktop, user Library, Applications, Music, Download and Movies. Unfortunatley, only a little bit of the Pictures folder was copied. iPhoto library (80 to 100 GB) was nowhere to be found, backup must have failed right then. I can salvage the drives (time machine drive, original hard drive with a few broken sectors, DMG-image of that drive, 1-1 copy of that drive with partition table repaired) but that only gives me files with numeric names and today's date on teh JPEGs (instead of the date the picture was taken).
Is there any way I can recover that iPhoto library? It appears the catalog file got corrupted because the hard drive (only 8 months old...) failed on a few sectors. If I understand it correctly, the catalog file on HFS+ file systems is where the folder structure and file names are stored in a B-Tree. I can't imagine that some i/o error during backup can totally annihilate that file when it was working perfectly before. Here's a few things I want to try out but haven't figured out how so far:
- Time Machine had to start a new backup. There's plenty of free space on that drive so there's a good chance there's old data left on it. Is there a way to restore files (including file names) and fodlers from deleted time machine backups?
- Is there any way to re-build that catalog file from what is there left on the original hard drive? I can't imagine 65 kilobytes destroys it all.
- Are there other ways to recover my iPhoto Library? The raw JPEG (and AVI) files with correct file names or metadata would suffice.
Thanks in advance for any help, I'll actually reward the person with a working solution, 5 years of photo memories are somewhat important. It really ***** that a failure during a backup destroys that...

Final Update:
The catalog file on the original hard drive could not be fixed. Seems like Mac OSX tried to repair the catalog file while the sectors this file resides on failed. To make things worse the partition table was also broken beyond repair, even overwriting the sectors with a new correct partition table didn't help. DiskWarrior found less then 100 MB worth of stuff, mainly Applications folders.
I recovered pretty much everything from the incomplete Time Machine backup by right-clicking the sparsebundle and browsing through the folders with the long alphanumeric names, looking for the version of the folder with the most files in there. All I was missing was part of the ~/Pictures folder, i.e. photobooth pictures and the whole iPhoto Library. My best option was to recover these files using data recovery tools.
DiskDrill proved to be the absolute best, fast, responsive, efficient, and the only one able to mount the DMG-file with no valid file system on it. As there were many i/o errors and broken sectors on the original hard drive, I made a copy of it using a free command line tool called ddrescue (the standard dd tool just aborted when it encountered the i/o error). ddrescue copied the whole drive to a DMG image, I had 56 kilobytes with errors on the first pass, but it managed to shrink that down to just 4 kilobytes (wow!) after the second pass where it tries to re-read the broken secors. It took about 24 hours for a 512 GB 2.5" drive (5400 rpm) but well worth it. Be advised that ddrescue is really persistent and tries everything to recover those last errorneous bytes. At the very end of the process, the read/write head of the hard drive just goes wild trying to catch the data on the sectors with different momentum. This works but I assume this is pretty damaging for the original drive. I also copied it all to a new hard drive (again using ddrescue) and tried partition and catalog repair tools on that (DiskWarrion, testdiks, pdisk, etc.). Still no hint of a good result.
I made a deep scan on the clone hard drive with DiskDrill. At the end (after about 8 hours over USB) it found 13 partition (I assume that's the Macintosh HD, EFI and some DMG files lying around) and hundreds of thousands of pictures. I restored some JPG files just to check the quality, some were damaged, some were good with all the EXIF data intact. I just made it copy all JPG files into a folder. I know the pictures taken from my camera produce JPGs larger than 1 MB and smaller than 5 MB, so I sorted them by size and moved the smaller and larger files into seperate folders. I took the remaining folder (100 GB) and just dragged it into iPhoto. It imported them overnight. Auto-Split by events and I got my library back, alas with different file names, originals and edited versions side by side, lots of duplicates, some damaged, some not. But hey, all the pictures in chronological order. Okay there was also one large event with all the JPGs without valid EXIF data landed inside, iPhoto just takes the file creation date (i.e. the date where the recovered file was copied). As far as I can tell, these are all just data corpses, halfway overwritten copies, random pictures from the internet, desktop pictures, etc.
I started to work my way back through the events, deleting the duplicates and renaming the events. There's an app called "Duplicate Annihilator" which apparently can find duplicate pictures in iPhoto and mark them for you. The free version only does 500 pictures but if it works, I'll get the full version. It can mark th eduplicate photos by adding something to the picture comment in iPhoto so you can manually review it all. Good stuff!

Help Incomplete Time Machine Backup and I can't set ownership options

Two days ago my iMac HD stopped working and I decided it was time to upgrade my machine so I purchased a new iMac with Mavericks installed. I seem to only have a partial Time Machine Backup located on my NAS drive, so I read various threads about how to manually retrieve files from the .inprogress file. I was able to browse the package contents and when I navigated to Macintosh HD the folder was greyed out and when I attempt to open the folder it looks empty. When I select get info the Macintosh HD folder shows almost 80GB and over 160,000 files inside. I tried copying the folder onto the desktop which failed and also onto an external drive formatted the same way as the NAS - Mac OS Extended (Journaled, Case Sensitive). Everytime I try it says something along the lines of me not having the ownership rights to copy the file over.
I tried going to the NAS drive and the mounted sparsefile and couldn't figure out how to get the ignore ownership on this volume option. When I go to Disk Utility it says Owners Enabled Yes, I can't figure out how to turn that off to let me copy the file over. I tried some recommendations about creating an Alias to Macintosh HD and also setting up Automator actions Get Selected Finder Items > Get Folder Contents > Open Finder Items > Copy Finder Items (to desktop or external drive) both of these failed.
I also don't understand why I can't view the files inside the greyed out Macintosh HD as get info shows many files inside. The sharing and permissions already says everyone can read. Is there anyway I can recover some of the files? It would be so great!
Thanks for helping me.

I solved the problem and I hope this solution can help others with incomplete Time Machine Backups.
1. I made sure hidden files were shown by pasting the following line into Terminal:
defaults write com.apple.finder AppleShowAllFiles -boolean true ; killall Finder
2. On NAS drive I have a folder called Time Machine Backup and inside that folder it lists the different users with Time Machine Backups. I double clicked the user with the incomplete time machine backup to mount it.
3. Once mounted there should be a folder called backups.backupdb > machine name > dateandtime.inprogress. I right click that .inprogress file and selected show package contents. This lead to another folder randomly named with numbers and text. Inside that folder you should see a greyed out Macintosh HD folder. The date of the greyed out Macintosh HD folder might read something like January 24th, 1984. This appears to be the date that the Macintosh 128k was first introduced. I read on another thread that the creation date of the folder is incorrectly set after a crash resulting in the greyed out folder.
4. Due to the NAS having ownership issues I was not able to drag either the greyed out Macintosh HD or the folder above it to an external drive or the desktop of my new computer. Automator didn't work either. Here is what did work: I trashed the folder with the greyed out Macintosh HD inside from the NAS and dragged it from the trash onto my desktop. The move took a few hours to complete and the files were now all successfully on the new computer.
5. Once on the desktop the Macintosh HD folder was still greyed out. The solution was to select in the finder: View > Show Path Bar, then search for any file you remember inside your backup. For example I searched the word download and files inside the greyed out Macintosh HD folder showed up. Left clicking the file confirmed the path, that it was from the greyed out Macintosh HD folder. Now you can simply right click one of the folders in the Path Bar and open in new tab if you have Mavericks. I still couldn't directly open the Macintosh HD folder in a new tab, but I could open any of the subfolders inside in a new tab, including the users which lets you access all the backup files. I tested in Mountain Lion that you can also choose Open in Enclosing Folder by right clicking the file that you searched for or right clicking the folder in the bottom of the Path Bar.
6. Once I was done organizing backup files, I turned off hidden files by pasting this line into Terminal:
defaults write com.apple.finder AppleShowAllFiles -boolean false ; killall Finder
This took me days to figure out how to make use of an .inprogress file and greyed out Macintosh HD folder.
Hope this helps!!!
