How do I repair a damaged controller for concatenated RAID

Hi all-- Bit of an emergency. My iMac has been crashing a lot lately and finally it's hard drive just up and failed. I have been doing hourly Time Machine backups to a concatenated RAID set (2 USB drives of 1 TB each). However, I think the iMac crashed while backing up and hosed the RAID controller.
I've since plugged the two disks of the RAID into my MacBook Pro to see if I can repair them. I can see the individual disks of the RAID in Disk Utility. I can even verify and repair them. But i can't do that with the RAID in the sidebar, and it won't mount on the desktop. When I try to eject it from the DIsk Utility file menu, it says disks are in use.
I'm pretty sure my data on the two disks is intact, but I can't seem to get the RAID to mount as the single concatenated set on a desktop, which makes it inaccessble. Is there a way to repair the JBOD RAID without losing all my data, so I can then restore from the latest backup to my hosed iMac?
thanks!
Chris

I'd just like to add some screen shots so you can see what's going on:
This is what's happening in Disk Utility. As you can see, all the slices are being seen, it says it's online, etc., but it's grayed out in the side bar and I can't seem to actually do anything with them.
And here's what diskutil in Terminal says. As you can see, it's finding it, and I can even "mount" Backup, but it doesn't actually mount it. What does the "rebuild: manual" mean?
Any advice on fixing this would be GREATLY appreciated. Thanks so much.
Chris

how to download repair of "missing WIA" for officejet J4550 All in one printer

HI knewsomga,
WIA is Windows Image Acquisition, it is a proprietary Microsoft driver model and application programming interface (API) for Microsoft Windows Me and later Windows operating systems that enables graphics software to communicate with imaging hardware such as scanners, digital cameras and Digital Video-equipment. - Source
Please follow the instructions below.
Please hold down the windows flag key and the R to open the Run box.
Type services.msc and press Enter
Locate Windows Image Acquisition (WIA)
Right click and open Properties
Stop the service from the General tab and then Start it again
Verify that the Startup type is set to Automatic rather then manual
Also, look for 'Shell Hardware Detection' in the list of services. If it is not enabled/started, make sure to enable/start the service, and make sure the Startup Type set as Automatically from its properties.
Locate the 'Remote Procedure Call (RPC)' in the list of services. If it is not enabled/started, make sure to enable/start the service, and make sure the Startup Type set as Automatically as well.
If the issue persist, the HP Print and Scan Dr might help, otherwise I suggest contacting Microsoft.

My PC had a virus which damaged some songs on my itunes library. How do I repair those songs that are damaged (they don't play the full length of the song)??

if the contents are purchases from the iTunes store then you can transfer the purchases from the ipad and put them onto the computer
go to:
file>transfer purchases from ipad
but if the contents are not from the iTunes store(3rd party) than you may have to use extraction software to pull those files out of the ipad and put them onto the computer

How do I repair a damaged time machine backup drive/remove pictures from library on locked/failing external drive

I have a WD 1TB external hard drive that I use as my time machine backup drive as well as to store a number of things including my iphoto library (due to its size of about 85 GB) as well as documents. I began using the WD 1TB external drive with my 2007 13" MacBook and when I purchased a brand new 13" MacBook Pro in 2013 I used the WD to transfer what I wanted to the new laptop. My new MacBook Pro is running OSX 10.8.4 (2.9 GHz Interl Core i7 with 8GB 1600 MHz DDR3) (not the retina display). The WD 1TB product # is WDBACX001... and it's only about one year old so I'm super bummed that it's failing and trying to take my life with it It has only ever been used with my two MacBooks, never with a PC.
The external WD was working fine until this week when I noticed that it wasn't appearing on my desktop. I rebooted, unplugged and replugged the WD drive in each USB portal, and still nothing. I ran Disk Utility to verify and repair the disk, which did force it to show up on the desktop again, though it made everything painfully slow. After running the repair function Disk Utility told me that the drive couldn't be repaired, and that I should backup whatever is on it and restore the WD drive. I managed to pull off most of the documents before it decided to freeze up my laptop (I had a couple of folders with a few documents each left), but I wasn't able to move the iphoto library over before the drive disappeared again. I got it back by running the repair option in disk utility, with the same message that the WD drive is failing and to back it up, and tried to move the iphoto library. It told me it would take 180+ days, and kept going up. I left it up anyway for about a day to see if it would change, and instead it gave an error message, and moved nothing. I can't open the library in iPhoto- it tells me it's on a locked disk. I checked the permissions and it's set to Read & write by me (the admin user) but then under that it says read only for "everyone." I can't get into the library to pull out my pictures, which I cannot afford to lose.
I would appreciate any help or advice on how to crack into my iphoto library on this failing drive to remove the pictures. I read a lot about DiskWarrior but I also read that it won't work on newer macs (anything after June of 2012 supposedly), so I'm wondering if that's true or not, and if not is that a good program to use?
I can't afford to take it to a professional right now, so any help or advice would be so greatly appreciated! Also if anyone then could suggest the best way to back up in two places (digitally and perhaps a better brand of external drive) it would be amazing.
If you need more info let me know!

If you're very lucky, you might be able to salvage the drive mechanism, and the data, by removing it from the enclosure and installing it in another one, or in a drive dock.

How to Reset the Sata Link Controller for Full Sata 3 speeds on an OCZ Agility 3

So I purchased a new OCZ Agility 3 drive, installed it into the main bay of my 2012 Macbook Pro, and the drive was running at half speed. I called OCZ and spoke to the guys about how to resolve this issue, they were very knowledgeable, but they had no ideas how to make thier Linux Live Tool work on the Mac, which gives us the ability to reset the controller. Here's what I did to get the full speeds out of my OCZ Agility 3.
- You will need a Windows computer, or the ability to create and install Windows on a Bootcamp partition on your Mac.
- Thumb Drive
- Lots of Patience
1. Open Disk Utility and create one partition on your thumb drive under MS-DOS Fat 32. Click the Options tab and select “Master Boot Record.”
2. Go to the OCZ forum and download the older Linux Live Tool version: OCZ_Tools_316-old.zip. From my experience, the newer version doesn’t work on the 2012 Macbook Pro.
3.Download the “Universal USB Installer” for Windows, and follow the steps to install the ISO to your Thumb Drive using the instructions located on the OCZ Forum. http://www.ocztechnologyforum.com/forum/showthread.php?99275-NEW!-Bootable-Linux -based-tools-for-OCZ-SSD-s&p=714047&viewfull=1#post714047
4. Once the ISO is successfully copied to the Thumb Drive, insert the USB stick into your Mac with the OCZ SSD installed in the Main Bay, Power On, and hold down the “Option” key. You should see a yellow hard disk icon that says “Windows,” select it and press enter.
5. Once the OCZ Tool loads up, click the “Green Arrows” to put the drive into Sata II mode. Shutdown the computer, power on, and check the System Profiler. The drive should be running at Sata II speeds.
6. Shutdown the computer and boot into the OCZ Tool, and click on the “Red Arrows.” This will reset the controller to its default mode of Sata III (Sata 6 Mode).
7. Check the speed of the drive using the disk speed test of your choice. The drive should now be running at full speed.
The biggest accomplishment here was actually getting the OCZ Linux Live Tool to load on a 2012 Macbook Pro. The newer version of the tool doesnt support the USB 3.0 drivers, so you loose the funtion of your trackpad and keyboard or bluetooth keyboard and mouse.
**Note: Black Magic Disk Speed Test Version 2.0 may give you lower numbers than expected due to the compression method in testing the drive. I would prefer using XBench or Disk Speed Test Version 1.0**
***Here's a link to a thread that explains how to properly install your OS onto the drive. If not done correctly, this can also cripple the speed of the drive.***

I can almost see a big grin appearing in Bob's avatar...
Hopefully his reply has given you a clue already?
If not, some explanation:
Many settings in the standard "Media" panel (for both video and audio) don't apply for publications that need to go the Folio-way. This panel is mainly concerned with lovely Flash stuff, but apart from the Poster frame and the Markers, it is useless for Folio's.
A quick guide: create a video with the necessary codec (H.264 for video, MP# or AAC for audio) at the required pixel size (exact width/height). Simply Place the file in InDesign, but don't scale it (or recreate and place a properly sized new video afterwards). Choose what to do with the Poster frame (and maybe some Markers), but all other settings are done in the Overlay Creator.
Check Bob Bringhurst's Tutorials and his DPS Tips app for more info. But I guess you get the idea now.

How do I repair a damaged dmg that won't mount and Dick Utility can't repair?

Apple Care gave me wrong instructions on how to create a disc image of my internal HD then erased it. Now I have a .dmg that has the same gigs as the HD but won't mount and Disk Utility can't repair. Tried to recover files with Data Rescue 3 but that isn't going so hot. Any suggestions?
Thank you

The Apple Support Communities are an international user to user technical support forum. As a man from Mexico, Spanish is my native tongue. I do not speak English very well, however, I do write in English with the aid of the Mac OS X spelling and grammar checks. I also live in a culture perhaps very very different from your own. When offering advice in the ASC, my comments are not meant to be anything more than helpful and certainly not to be taken as insults.
I guess that it's a moot point to ask if you didn't test the dmg before you erased the drive. Do you have a Time Machine or other type of backup?
If not, it's a hard lesson to learn, but I would guess that unless you are willing to pay for expensive outside data recovery service, all is lost and you are starting over.

How do I repair a damaged song on the IPhone?

I have a song that only plays 1/2 of the lyrics and then stops. It appears that the song is damaged and didn't download correctly since I can play the song with no problems from the laptop.
How can I re-sync this one song? I need toi first erase it from the IPhone. I have tried re-synching the songs but the problem persists.
Thanks,
John Carpenter

Is it just the lyrics that stop? or does the sound quality degrade? or song just stop playing altogether?
Does it play fine in iTunes on the computer? or some other player? try iTunes.
is it an mp3? if so, try converting it to AAC and resync. If that fixes it then the mp3 is corrupt in some way that the phone is suceptable to, try reripping.
To replace the song on the phone you will have to delete it from the playlist then sync (to delete from phone) then re-add to playlist and re-sync.

How do I repair a damaged hard drive?

does it have to be replaced or can it be fixed using soft ware?

With no install drive and a potentially flaky boot drive there is no guarantee of success. Here's some schemes you can try.
1. Boot in safe mode. I believe it does a fsck (file system check) of the boot drive.
2. Related to 1.
Resolve startup issues and perform disk maintenance with Disk Utility and fsck
3. Ggt yourself an external drive and hope you can clone the boot drive to it using Carbon Copy Cloner (or Super Duper). Then boot from the external and try to repair the original boot drive.
Of course I shouldn't have to say that you should always have a backup (backups) of your drives anyhow.
4. Contact apple to try to replace your installer dvds.

How can I repair the shuffle feature for IPOD?

My 3g phone recently lost its ability to shuffle music. I plays music just fine, but only one song at at time. The same song will repeat until I manually select a different one. The shuffle button has no effect.

Turn off the repeat feature.

My phone is dissabled and i dnt syc to the comp b4 how can i repair it

my phone is dissabled and i dnt syc to the comp b4 how can i repair it

Hey korodi,
Thanks for the question. The following article provides some solutions if your iPhone displays a "Disabled" message, and you have never synced with a computer:
iOS: Forgotten passcode or device disabled after entering wrong passcode
http://support.apple.com/kb/HT1212
If you have never synced your device with iTunes, or you do not have access to a computer
If you see one of following alerts, you need to erase the device:
"iTunes could not connect to the [device] because it is locked with a passcode. You must enter your passcode on the [device] before it can be used with iTunes."
"You haven't chosen to have [device] trust this computer"
If you have Find My iPhone enabled, you can use Remote Wipe to erase the contents of your device. If you have been using iCloud to back up, you may be able to restore the most recent backup to reset the passcode after the device has been erased.
Alternatively, place the device in recovery mode and restore it to erase the device:
1. Disconnect the USB cable from the device, but leave the other end of the cable connected to your computer's USB port.
2. Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. Wait for the device to shut down.
3. While pressing and holding the Home button, reconnect the USB cable to the device. The device should turn on.
4. Continue holding the Home button until you see the Connect to iTunes screen.
5. iTunes will alert you that it has detected a device in recovery mode. Click OK, and then restore the device.
Thanks,

An iTunes folder or the iTunes library.itl file is damaged?
How do I repair the damaged folder?
You don’t.
If iTunes is running the iTunes library.itl file was rebuilt.
You can quit iTunes and restore the iTunes library.itl file from your most recent backup.
You do regularly backup you computer, correct?
If not, File > Add to library and select /My Music/iTunes/iTunes media/Apps/ folder.

How much I repair for my Macpro 13inch damage Motherboard by liquid?

How much I repair for my Macpro 13inch damage Motherboard by liquid in singapore?

One thing to keep in mind is that any electronic component inside your computer could be damaged, so you could end up paying to replace a lot of other parts later. (You also may not... it's a bit of a gamble.) It's your decision whether to repair or not, of course, but I personally would never consider repairing a computer with liquid damage. I would consider it a loss and would just replace it.
BTW, hope the smog is clearing up where you are!

How to repair/open damaged .nef files on mac?

Sorry if this is in the wrong place...
I am using my sisters Apple refurb Mac Air, OSX 10.8.4
Camera is a Nikon D3100
There are around 3000 pictures. Basically I made the mistake of using a crappy card reader to open my files on her computer. A zeikos one. Periodically, it would eject itself, and eventually it corrupted all 3000, some jpg pics included. I ran applexsoft SD Card Recovery and managed to recover all 3000 pictures after a couple of tries. I could see the pictures on the preview, with the watermark, and they went into the recovered file folder. I checked the file sizes and most average between 10-15 mb. Now they wont open in preview or iPhoto, saying it is unrecognizable or damaged, and does the same for the .jpgs. I have opened .nef pictures on her computer before. It's been a while since I have had a mac so I am a little fuzzy on what is supported or not. What I am wondering is:
If the preview on the recovery tool shows the pictures, is it likely that these files are salvageable?
How can I view them and what program is best?
Most of these pictures are not valuable, I only need a select number, so if I can't get all of them, would it be possible to select only the ones that I need with a particular program?
If they are indeed damaged, how can I repair them?
I've downloaded something called Stellar Mac Photo Recovery, but I don't want to run anything until I get some info...
I can't keep too much data on here, so the smallest effective program would be best...
To clarify, the pictures are currently on the laptop, not the SD card. Though they're still technically on the SD card, I am asking for help to repair the files on the computer.
Please help... I wish I could have backed these up periodically, and usually I download the most important pictures to my iPad and upload them to an img host, but I lost my iPad card reader. I'd really appreciate any help! Thank you (:

Only if you export them in the correct format.
If you just save them they will be in the Apple format which will not work on the PC.
