Volume data underrun
Anyone know what this is and/or why this happens?
History - I have been having intermittent hangs in Final Cut Pro (FCP) during rendering. Upon checking the system log I saw a data underrun on disk 20, one disk of a SoftRaid volume. Upon opening the volume, I see there are several i/o errors on the volume, not the disks that make the volume. When I clear the errors, try to render again, then force quit FCP and check the system log, I see the same as below and more i/o errors. This is repeatable. I notice there is just under 4GB free so I look to delete some files and find capture scratch from another FCP project that can be deleted. When I open it up, I see I had the exact same problem I am having now, with that project - two projects with data on the same SoftRaid volume having the same problem. I did delete files so I have 22 GB available now, but the problem still occurs. This disk stores only the video files, no rendering files.
For whatever reason things have fixed themselves. After the last os update, things are running better. Even compressor is working again.

I noticed today that my last back-up was this a.m. and it has tried several times to back up since but I keep getting this message
Time Machine couldn’t complete the backup to “TimeCap”.
The backup disk image “/Volumes/Data/ MacBook Pro ."sparsebundle” is already in use.
I have never had this problem before and don't know what to do. I am not that great around computers so if anyone can help I would appreciate it. I did try to do some research but could not understand any of the content I read. I sure don't know what "sparsebundle" is and this is the first time I ever heard the term.
If anyone can help woold appreciate it.
I have Version 10.9.1This is a standard issue..
Been around since LION but you missed out.. !! Well the old rule applies.. there are three types of Mac users.
1. The bugs have bitten you, and you have done the work arounds.
2. The bugs are biting you and you are now trying to find out what is going on.
3. The bugs will bite you. And in the meantime you laugh at everyone with problems and say it must be all their fault. Doesn't happen to my system.
You were simply in the last group.. now, with the wonders of mavericks to help, you got bit.
The solution is simple.. unplug the power cord from the TC .. count to 10.. power up the TC again.
No luck look at the more technical help.

Your naming might also be an issue if this continues to happen.. see C9. -
More from the Time Machine Buddy: "Node requires deep traversal:/Volumes/Data" and "reason: kFSEDBEventFlagMustScanSibDirs"
I am using a Mac G5 with Leopard. My LaCie data drive failed and I replaced it with a WD MyPassport drive, at which time the failed backups began. The recent file updates do appear in Time Machine, but it appears to back up everything since the last completed backup.Hi Norm,
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
(Repair both Drives)
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.) -
MacPro backed up to Time Machine, added Mac Mini now get "The backup disk image “/Volumes/Data/Jerry Booher’s MacBook Pro.sparsebundle” is already in use." error when Mac Pro tries to back up
It is standard Mountain Lion error due to the networking ability which is comparable to wet string. (actually that was lion.. it dried out some with Mountain Lion.. higher in the hills perhaps!!)
See C12 and C17
http://pondini.org/TM/Troubleshooting.html
But many people are suffering the same issue..
And the above is even a little out of date.. you might need to do a reset to the TC.

For the past several days, I have been getting this message during backups:
Time Machine could not complete the back up. The backup disk image "Volumes/Data/bhoppy2's iMac.sparsebundle" could not be accessed (error-1). When I click on the 'help' icon on the message, it reverts to a blank page, and I cannot find anything online regarding the term 'sparsebundle.' In addition, I cannot access previous backups any longer.

I get this error message when I try to back up my laptop:
' Time machine could not complete the backup. The backup disc image "/Volumes/Data/Lou Ann Buesing's Mac Book Pro. sparse bundle' is already in use. "
Anyone know how to fix it?Reboot the TC.. Sometimes you need to reboot the whole network.
This is what comes of Lion and then made worse in Mountain Lion of Apple not spending enough time to fix the bugs.

C17 can be related I think. -

Expect to see this error again due to a bug in Lion (and Mountain Lion).

Time Machine could not complete the backup.
The backup disk image "/Volumes/Data/Name's iMacsparsebundle" could not be accessed (error -1 )I checked the pondini fixes and ended up doing the following - in case this could help someone else with OSX Lion and Time Capsule... http://pondini.org/TM/Troubleshooting.html
First, I downloaded and used Airport Utility 5.6 instead of 6.1 - BTW, I had to attempt download and installation THREE times before the program actually installed. Be persistant.
Pondini #5: It's possible some names (of all things!) may be a problem. See item C9. I had to re-name my Mac, Time Capsule, network, etc... to remove all apostrophes and spaces.
Pondini #7: If you have WD SmartWare installed on Lion, it's not compatible, per RoaringApps, and there are reports it can cause this problem as well. Use Western Digital's uninstaller, or delete the app from /Applications and the files com.wdc.WDDMservice.plist and com.wdc.WDSmartWareServer.plist from /Library/LaunchDaemons. There may also be a file in Library/Application Support.
I then had to shut down computer, unplug Time Capsule, unplug modem; plug everything in again, then reboot computer; then had to go to Apple- System Preferences- Network- and reselect my Time Capsule to connect to WiFi again.
Then opened Time Machine preferences again and attempted back up - it worked! -
My time machine does not back up and giving me this error message: The backup disk image “/Volumes/Data-1/Amiel’s MacBook Pro.sparsebundle” is already in use. Pls help.
Make sure that there are no other Macs backing up at the present time.
Pull the power cord from the back of the Time Capsule
Count to ten
Plug the power cord back in
This will "fix" things about 98% of the time. Post back if you are in the unlucky 2% category. -

I have not been able to back up for2 days. Time machine error message: /Volumes/Data/David’s MacBook Air.sparsebundle” is already in use.
What now?
Macbook Air.
Was working fine for the past year until now.See more like this on the right.. this is the most common error reported here since mountain lion came out..
Or read C12.. http://pondini.org/TM/Troubleshooting.html
Or just restart the whole network.. in right order from off.. modem.. router / TC.. clients 2min gap. -
When back up to time capsule I get the message no access to backupcopyfiledisc/Volume/Data/Terjesumac.sparsebundle ( error-1)

Time Machine did not back up:
Time Machine Error; ("The backup disk image "/Volumes/Data/My MacBook Pro.sparsebundle" is already in use.")

Thanks!You need to be careful Bob.. people might take this literally.

Call the exterminator to get rid of the bugs in Lion and Mountain Lion.
