RAID drive corrupted by Time Machine

Hello, I believe that Time Machine has corrupted on of our RAID systems and would appreciate any help and advice that you can give.
Background: G5 Quad, Sonnet E4P controller, RAID box with port multiplier. There are 5 drives in the box; 4 are in the RAID, the other is an independant disk not associated with the RAID. We were running 10.4 with no problems. After Installing 10.5 (with Time Machine backup to the RAID) we experienced frequent system crashes and went back to 10.4. Everything worked great until rebooting the system and the RAID. At startup, we now get the message "The disk you inserted was not readable by this computer". We have 2 RAIDS, one still works fine, the one that was set up with Time Machine is toast.
Disk Utility reports the RAID as Online in the right column, but "disk10" is grayed out in the left column. It reports the 4 drives in the RAID as Offline.

Good News: I was able to see the files in the RAID with a demo version of DataRescue, and all the files are there. Here's the contents sorted by Date, with the most recent items expanded. Lots of modified files related to the hard drive, and at the bottom is VolumeConfitg.plist and .com.apple.timemachine.supported. Any idea how to restore my RAID?
I can purchase this program or one like it, and restore the files from the RAID to another drive... but I'd rather get my RAID back. Thanks!

Here's the drive contents sorted by time, most recently changed files showing first. Thanks!

Complicated corrupted main drive and lost Time Machine back-ups question

Here's tough one I can't pin down answers to: I have an iMac Early 2008 running Lion. The main hard drive system (probably) corrupted over the course of 2-3 months until it became unusable. I had Sophos on it, but removed it about a month ago and reliability improved but only for about a week. Finally the hard drive crashed. I used the Recovery partition while able to have Disk Utility add a second partition to my back-up drive, which contains Time Machine back-ups, my iPhoto folder and a few other files but no system. I installed Snow Leopard from disk to the new partition, checked the first partition, which seemed fine, then upgraded the Snow Leopard partition to Lion and updated and ran under a temporary user. Next I explored the main drive, which Disk Utility said was fine, but doesn't always show up. While in Disk Utility, I noticed that the first partition on the back-up drive showed up as empty! After some panicking, I've a second back-up drive on the way, but how do I access the TIme Machine back-ups, get my original user back and get access to over 15 years of files that are locked into that user?
My (2nd) back-up drive arrives tomorrow, so I'll able to get to work soon.
Thanks for any help.

Ok so wahat you mean is I need to name a partition "Time machine" in order for TM to back up any volumes and TM will always start with the volume titled Timemachine ?
so as I stated
A. All my OS applications _________Rename this to time machine or can I ues the volume name it is now?
B. All my files for those applications ---------Once that is done TM will back this up?
C. All My Itunes / Music etc---------Once that is done TM will back this u last?
Also I did a test run and I geet the error msg that the backup disk of my OS needs 1.36 TB but only 1.34 exists. The orignal OS disk has only 232GB of data why is tome machine asking for all that space?
I set the partition at 1.34 so there would be way more than enough space to copy.

I would like to connect an external hard drive to my time machine and use it as a network drive to store itunes and iPhoto how do i do this

I have just purchased a new my book hard drive and would like to connect it to my time capsule and store my itunes and iphoto contentent there to free up space on my internal hard drive . Can this be done and what is the process?

I'd like to store my Aperture /IMovie Libraries on an external hard drive.
That is fine and recommended.. use the fastest disk you can afford.. ie Thunderbolt>USB3>FW800>USB2.
In addition, I'd like to partition the external hard drive so that Time Machine can use it to both back up my IMac and the external library drives.
Let me be clear.. you want to partition the one disk.. use it for TM and move your files to the external disk.. and then backup to the same disk.. You can do it.. but that is not a backup.. that is an experiment in how long you can get away with running files and backups on the same disk before you lose everything.. like Russian Roulette.. pull the trigger enough times and laws of probability will do you in.
You must have backups on a different disk .. otherwise it is pointless.
Can I set up a RAID 5 format for redundancy?
No.. you can buy special USB and Thunderbolt external drives that support RAID..
BUT that is still not a backup.. let me show why.. you make a silly move and corrupt your file in aperture.. it is not that rare.
Raid will corrupt all copies of the files.. it is replicated across all disks.
Delete a photo it is deleted across all disks.. you have no recovery.
Alway, always consider RAID system one disk.. backup onto another disk.. and if the photos or movies are at all important to you.. ie your family .. make another copy and store in a relatives house.. There is no such thing as too much redundancy.

Can I use my older airport express with an ext drive to backup time machine wireless, Can I use my older airport express with an ext drive to backup time machine wireless

Can I use an older (flat) Airport Express to attach an ext hard drive and backup time machine wirelessly? and how?

can I then connect a HD with itunes music and photos?
Now we are drifting from the original question.
Im alreadty using the HD attached to my Mac Pro...can I just connect it to the Extreme and access it wirelessly with any device on the wifi net?
You may get another opinion on this from another user, but I do not recommend this either, based on a number of experimens over the years with this.
Access to your data on the drive will be much slower. iTunes will tend to "lose" the library this way and you will have to re-point the iTunes application at the library on a regular basis.
Things are even worse with the iPhoto library. The experts over in the iPhoto support area strongly advise that you do not do this, since any break in communication between the iPhoto application and iPhoto library can easily corrupt the entire library. A wireless connection makes things even more dicey.
My advice......Use a drive connected to the Extreme for storage or other backup copies of data.....not for "working" files or libraries.
But, you may get some other opinions from users here.

Use external drive for both Time Machine and storage for Back to My Mac

Hi all,
I have been "a Mac" now for over a year and just keep finding cool new things that make me happy I switched. The latest thing is Back to My Mac offered with my Mobile Me account. With a rather convoluted mix of PC/Mac/iOS devices to manage - best $99 I ever spent btw...
I also have a 1TB Time Capsule that I have been using with Time Machine to back up all four of my Mac computers at home. Needless to say, the 1TB is really struggling to handle the amount of data being backed up and certainly leaves no room for anything else.
What I wanted to do was to attach a larger external hard drive via a powered hub to the USB port on the Time Capsule and use it for Time Machine backups while using the internal 1TB drive with Back to My Mac so that I can have remote access to all my data from anywhere without having to leave my computer running at home all the time in order for my laptop to "see" it when I'm away. And, yes, the amount of that data far exceeds what any level of Mobile Me subscription can offer! I should also mention that the hard drive is the only USB device connected through the hub to the Time Capsule at the moment. There are no other devices that might be "getting in the way".
I'm thinking maybe all this is asking too much without the addition of a dedicated file server (Mac Mini, perhaps - not a purchase my budget wants to make).
I understand that the Time Capsule doesn't support partitions, so I bought a Western Digital 2TB Elements drive, connected it to my Macbook Pro and used Disk Utility to reformat the drive from the incompatible NTFS it shipped in to a single, Mac OS Extended (Journaled) partition. I then made two folders on the drive, one for Time Machine backups and one for Back to My Mac remote storage/access. Great.
However, when I connected the 2TB drive to my Time Capsule I could not see it at all. Time Capsule was reporting problems in the way of a disk error. From within my Airport Utility, I could see the trouble was the external drive. The utility suggested connecting the drive to a Mac and using it's Disk Utility to troubleshoot.
I followed through, checking the disk, etc. and ended up reformatted the drive on my Macbook Pro yet again with the same specifications as before but without the folders and reconnected it to the Time Capsule. Same deal. But now, I can't even remotely connect to the Time Capsule at all. I can see the Time Capsule in the shared area of my Macbook's Finder but can not connect. The connection tries and fails even before it gets to asking me for username and password credentials.
Long story short, first of all, I suppose I would like to know if I'm asking for the impossible?
Second, if what I want to do *is* possible, what steps do I need to take to make it so?
Thanks in advance for any advice or suggestions you might have.

Well, I have now reformatted/partitioned my poor WD Elements 2TB drive about a dozen times as well as restarted my 1TB Time Capsule so many times it's no wonder it's as confused as I am! <G>
Last night, at your suggestion, William, and in respect for your continued support, I tried creating two 1TB Mac OS Extended (Journaled) partitions on the WD external USB drive, both with GUID partition tables. Both volumes mounted to my laptop's desktop flawlessly and without issue.
Once the external drive was connected to the Time Capsule, however, it was a crap shoot as to whether or not the drive was recognized at all, reporting a problem with the disk, or, even at one point, mounting one of the two volumes but not both. <sigh>
I read somewhere on the Internet that you need to restart the Time Capsule for volumes on an external USB drive to be recognized.
So I tried that. I connected the freshly partitioned/formatted disk to the Time Capsule and restarted it. This succeed in removing the issue of reporting a nameless drive with a capacity of 0MB. It then reported the drive with its correct name but would not recognize whatever volumes in whatever partitions that particular crack at it contained with the exception of the once, as I mentioned above, when only one of two volumes mounted correctly and was listed with the right name and capacity on the Time Capusule's Setup's Disk tab.
At this point I have given up on my goal to use the external drive with Time Machine to back up my Macs or to hope I will ever be able to see its contents remotely via Back to My Mac. All I would like to do now is simply find a reason why I can't get it successfully connected and playing nice with my Time Capsule in the first place!
Any further suggestions or advice as to what steps I might take next would be greatly appreciated.
Thank you all.

How can i put music drive AND a time machine drive on wireless network?

Right now I have a MacBook with ONE external drive with my music and movies… and ANOTHERexternal drive for my backups.
I would LOVE to figure out how to hook both the music drive and the time machine drive to a wireless router so the only plug I have for my laptop is the power plug.
I already have a NetGear wireless router… but it only has ethernet ports out, no usb.
What would be the best/easiest way to network these two external hard drives?
tx!

Another option, where you can still utilize your existing drives, is to consider a dedicated NAS device that supports both Time Machine and iTunes functions. One such NAS device is the Synology DS415+. It would be far superior than what you have now. Albeit at an additional cost.

Trying to use a new, larger external hard drive for my Time Machine backup. However, every time I start the backup, it gets started then fails. And, I can't delete the few files that did save on the external. Sort of a catch 22. Any ideas?

Is it a USB hard drive? USB hard drives have the problem of not giving full speed if they are hooked up on the same bus as keyboards and mice. Double check your profiler to make sure that is not a problem. If it is Firewire, make sure there aren't other firewire devices in use at the same time. I recommend not only keeping a Time Machine backup, but also a clone, and if you do use Time Machine, to make sure the Time Machine drive or partition is at least twice the size of the original drive.

I have a 250GB western digital external hard drive for my time machine backups. if i just want to backup and recover my photos and movies how do i do that with time machine?

I have a 250GB western digital external hard drive for my time machine backups. I did not download the software that came with the external HD. If I only want to backup my photos and movies from my Macbook how do I do that in Tme Machine with my external HD?

Format the HDD in Disk Utility>Erase to Mac OS Extended (Journaled) and the open System Preferences>Time Machine and set up the external disk as the Time Machine HDD. Then look at the Options, and exclude what you do not want backed up.
Ciao.

How do you remove back up data from the memory storage? my storage data states that i have over 80gb of data used for back ups and i dont know why as i use a external hard drive as a time machine .now my 250gb flash storage is nearly full

how do you remove back up data from the memory storage? my storage data states that i have over 80gb of data used for back ups and i dont know why as i use a external hard drive as a time machine .now my 250gb flash storage is nearly full.. HELP!

When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
See this support article for some simple ways to free up storage space.

How can I reformat my external hard drive from the time machine format to regular format?

Ok so when first starting out I got an external hard drive for my time machine, little did I know I would run out of space really fast and would need to buy a bigger and better hard drive. Now that I did that, I have my old hard drive that I would like to use for copying material form my laptop to my desktop. However, it is still set as my time machine and tries to back up my lap top every time I plug it in. Also, it says that about half of it is still filled with stuff. I erased everything on it. I just want to reformat it so that it is like I just bought it.

I had the same idea as you however when I tried going to Disk Utility and I tried to erase it an error message came up telling me that it is unable to erase.
Unable to erase, or unable to unmount?
If Time Machine is trying to back up to it, or some other process is using it, Disk Utility won't be able to unmount it. Turn Time Machine OFF; if you have the drive open via the Finder or any other app, close it or quit the app(s).
At worst, start up from your Install disc or other alternate source and erase it from there. If you're not sure how to do that, see the yellow box in #1 of Formatting, Partitioning, Verifying, and Repairing Disks.

Can I set up multiple usb hard drives- one for time machine and a second for media? Can one also print wirelessly with an old HP C6280 printer?

Yes.

Possibly by using an Airport Express, but depends on what type of port connection the printer requires.

I have suddenly become unable to access photo library iPhoto (vers 9.5) on my external drive. And time Machine will no longer back up to the same external (LaCie) drive. Appreciate all suggestions. The drive does show up on my desktop....

I have suddenly become unable to access photo library (iPhoto vers 9.5) on my external hard drive. Also time machine isnt backing up to same external hard drive (LaCie). The drive does show up on the desk top, but when i open iPhoto the library isnt listed, so I cant option click.

First, one should not try to run an iPhoto library from the same volume/drive that is being used by Time Machine for backups. TM will continue to fill up the drive thus squeezing out iPhoto from being able to be opened and used. Also that doesn't allow you to let TM backup your library as it does with other files on your boot drive.
If you partition the EHD into two separate partitions you can run the library from it but that won't let TM backup the library which is important.
Are you able to see the library on the EHD via the Finder? If so copy it back to your boot drive and open it there. You may have to do some fixing on it.
Solution is to either run the library from the boot drive or get a second EHD to run the library from and let TM back it up along with your boot drive.

HT201250 how do i add external hard drive to my time machine back up

how do i add external hard drive to my time machine back up so that I may view the files independently on apple tv please?

To elaborate on above. I am looking to add about 300gig of photos on an external hard drive to TC.
Once I do this I believe I can then have itunes source its photos from TC without having them stored directly on my iMac?
Then I am assuming once I keep itunes on with home sharing I can stream these photos through Apple TV?
My inital problem is getting the photos onto TC in an individual folder not just a backup folder....is that possible or what would you suggest please?
