Disc image input/output error

When burning a disc image using disc utility, I get the ever so popular input/output error message. I cannot find anywhere on these posts a solution to this problem. It is not dirty discs, etc. It happens when I try to copy dvd's... which are not licensed, etc.

Could be so many things, Input/Output errors are generally loosing contact with a device for a variety of reasons, do you get any error # with that?
Open Console in Utilities & watch for more info whn you try to burn, or open the Disk Utility Log if there.

  • Restoring .dmg image from external to Mac HD in Disk Utility: "Unable to scan image (Input/output error)"

    Hi guys,
    So I've got a problem with restoring the image backup I did (using Disk Utility) of my 500GB HD on my MBP which was acting weird or maybe even crashed a few months ago. After creating the backup image and putting it on my external device, I installed Mavericks back to see if everything was alright (mainly the HD) and everything seems okay.
    I did try restoring the backup image through disk utility before installing mavericks (thus erasing everything again on the HD) AND after. But nothing..
    The whole process starts fine and then it starts scanning the image when after maybe a good 10-15min in I get a message that says that it was unable to scan the image. I tried verifying the disk(s), everything came out "OK". Also tried scanning it through Images > Scan image for Restore... with the same results.
    While searching I've seen people getting messages like "Unable to scan filename.dmg (Invalid argument)" and "Unable to scan filename.dmg
    (Internal error)" but none have (Input/output error)
    The screen grab is below.
    I also came across something about using terminal/commands but I'm not that savvy with it, especially considering that those there had issues with either mounting or trouble finding the image.
    I've also tried moving the backup image to a different external device 2TB and also the desktop because I read it may have to do with the format of the externals or maybe free space. But THEN I would get a message saying
    "The Finder can't complete the operation because some data in "Mac HD Backup.dmg" can't be read or written. Error code -36"
    Fyi ALL my externals are HFS+/Journaled and the backup image format was compressed.
    I REALLY don't know what to do next. Was it the wrong move to create a dmg image? Have I lost everything? Is there still a way out?
    If anyone can help, THANKS!

    If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

  • Disk Utility: Create image fails with input/output error

    Starting to create an image and saving it into an external hard drive (MacOS extended Journaled).
    It starts after less than 60 secs it comes out with an error : Failed to create the image (input/output error)

    If you don't mind I'd like to discourage you from backing up a drive onto a disc image file no matter where you plan to save it. Disc image files can be very problematical when it comes to trying to restore the backup. Furthermore, you cannot boot from a disc image. If the disc image file becomes corrupted then you have no backup.
    I would like to propose that you think about a better way to backup your drive. You can clone the drive to your backup drive. It's easy to do using Disk Utility's Restore feature. A clone backup is not only bootable but you have direct access to all the files on the backup.
    In order to make a bootable clone open Disk Utility. Select Disk Utility Help from the Help menu. Search for +duplicating a disk+. Click on "Duplicating a disk" at the top of the list of articles. Follow the directions.

  • "input/output error' when making disc image from DVD

    I've had problems installing Logic, and a Pro Apps Genius at Applecare suggested I try making an image of the problematic DVD (Audio Content 1) and then trying an install that way.
    While I can make an image of the Install disc to my desktop fine, the Audio Content 1 disc reports an "input/output error".
    This means I'm unable to copy the disc and then successfully install my Logic Studio.
    Any ideas?

    Thanks for your answer.
    Yes, I thought that might be the case - but I'd taken my Mac and Logic disks to a Genius bar, and the 'Genius' had said he'd fixed the issue. I just wish he'd explained what he did and why he didn't replace the faulty disk(s)!
    But is there any way around having the claim a disk, now I'm living abroad and my 'warrantee' has run out? It's going to be a pain in the fundament trying to claim a replacement set.

    Welcome to the forums.
    Not exactly alot of info to go on here. Try reading up on the "How to post" article on the wiki.
    As for the trouble at hand. With the limited info given, I'd say start off with running some health checks on your disk (smartctl, fsck,...).

  • Disk Utility - Input/Output error when creating disk image

    Hello!
    A few days ago I was unable to turn on my Macbook Pro, and was stuck on the white screen. I've been searching around quite a lot on this forum, and before I try fixing anything, I REALLY need to back-up my files! I just bought a 2TB hard-drive, which I have partitioned to GUID and Mac OS Extended (Journaled), (it perfectly works on another Mac).
    I now want to attempt to create an image of my harddrive (Macintosh HD) onto my external drive (which is empty). I've tried doing this both in 'read-only' and in 'compressed', but about halfway through, I receive a message saying "Unable to create 04/2014 backup.dmg (Input/Output) error".
    I saw on another similar post that I might want to install DiskDrill or DataRescue. I'm fairly sure this is impossible for me to do, since my screen is completely white, and I'm unable to access my desktop.
    I can only access Disk Utility through pressing command+R when starting my computer. Hence, I need to successfully back up my files through Disk Utility...
    I'm aware that my HD may be corrupted since this is happening, but there must be a way for me to put an image on my external HD?? A few days ago, when I clicked on Repair Disk it said "Impossible to repair: invalid node structure". But now, it says that "Macintosh HD appears to be OK". I have no idea what's changed... And I can still not start my computer past the white screen...
    I'm very bad with IT and computers, and have extensively tried to fix this on my own, but I'm now stuck here, with this "input/output error"...!
    Any suggestions would be greatly appreciated! Thank you!
    PS: I do not have Applecare, this is an old computer from 2009.

    Thanks for your answer.

  • Input/Output error message when uploading a DVD to copy.

    Hi All,
    I have been getting this message "Unable to Create: input/output error." when trying to upload a dvd to burn using Disk Utility . At first I thought it was a problem with the disc so I had a friend of my send me another copy. This was 2 discs. The first disc I get the error message the 2nd disc copied perfectly. My friend sent me the first disc again and I still get the same error message. It uploads about 2/3 of the disc and then the error message shows up. I tried on both my desktop and laptop and same error message on both. Both are using Leopard.
    This is not a copyright protected disc. This is a personal disc.
    Any help would be greatly appreciated.
    Thanks in Advance.

    I have exactly the same problem. I'm trying to create images for all my DVDs created on Windows Vista. Unfortunately, when around 80% of the disk is already read, I'm getting:
    6/4/08 9:54:06 PM Disk Utility[1872] Unable to create “Lena - prawie 2 lata.cdr”. (Input/output error). I have been able to reproduce this issue on 3 DVDs so far (all filled with 4GB of data).
    The only DVD that I was able to duplicate was 1.4GM is size. Any suggestions?

  • External Hard Drive Input/Output error

    I recently started having problems with an external hard drive setup that I did not have problems with prior to upgrading to 10.5.5 and trying to setup the drive to be compatible with Time Machine.
    The hard drive enclosure that I have has 2 bays for two SATA drives. I have used this enclosure without any problems until I tried to get 1 drive to act as the backup drive for Time Machine and the other to be storage. I formatted them using Drive Genius. I used the option for GUILD or GUIL which it said was the better format for using with Time Machine.
    The first problem I ran into since upgrading and reformatting the drives is I got an "input/output" error the first couple times I connected the drive via USB to my Mac. I could still use the drives but I got weird errors every once in a while like "input/output error" or "device was not ejected properly" even though the device had not been unplugged.
    Now the drives will not mount using OS 10.5.5. The drives show up when I open Disk Utility, but I cannot get them to mount. I have ran Disk Utility First Aid, and it says the drives are fine. There is one error that shows up when I run the "Repair Disk" feature. It reads "Invalid content in Journal". But Disk Utility also says "The volume was repaired successfully".
    I have seen some posts when I do a search in google about this issue and it seems this is a known issue. Every suggestion I see says to insert your Tiger DVD and reformat the drive using that and the problem will be solved. The only problem with that is I have a lot of important files on the drive that I cannot lose. I had the files backed up until I moved them to the new drive a while back. Now I do not have a backup because I was in the process of switching to bigger drives and erased the old drives after doing so because everything was working fine.
    I am hoping someone out there may have some suggestions (other than erasing the drive) to get my dives to mount so I can transfer the data off to another drive and reformat after.
    Thanks,
    Paul Rugg

    Thanks for the suggestion.
    Do you think that would work better than Drive Genius? I bought Drive Genius 2 and it does not even see the drives when they are plugged in unlike Disc Utility which can see the drives but cannot mount either one.
    Maybe this following post I made to a different questions may help. The data on the drive is other buying another program for if it will work. I think my next step may be to go over to a friends place and try to mount the drives on his computer and transfer stuff off if they connect.
    text below posted to other question relating to external hard drive problem.
    I have recently had the same mounting issue with my new external hard drive. I just purchased a new 750Gb Western Digital Sata drive and got everything transfered over to it. Immediately, I got an error saying that the drive had been ejected incorrectly even though it was still plugged in. I was a little curious. I restarted the computer (hard drive still plugged in via USB 2.0) and the drive showed up just fine. I plugged another 250Gb drive into the same case (2 bays) and the 250GB drive showed up just fine.
    Well, I then noticed there was an OS upgrade available when I ran Software update so i ran it and when I rebooted the drives were gone. I can see the drives in Disc Utility, but they will not mount. Drive Genius cannot see either disc. Disc Utility says I need to repair the drives, but when I do it says they are fixed but they don not mount.
    The problem really seems to be related to mounting USB external drives. I got ahold of 2 seperate external firewire hard drives and one shows up just fine while the other has the same problem (both work on other systems. I would try wiping the drives and reformatting but ALL MY stuff is on them and not everything has been backed up. Yuck! I have not tried connecting my hard drive to another Mac yet.
    The drives being used are #1 Maxtor Maxline Plus II 250GB SATA/150 HDD 1.5b/s 7Y250m00654ra
    and #2 Western Digital WD7500AACS WD Caviar GP Green Power drive.
    I have another post similar to this and I have not received any feedback, but I have been doing my own searching and have found similar posts on the net.
    Anybody have any clue what might be going on here? It really seems to be related to my upgrade.

  • External Hard Drive not Readable & Input/Output Error?

    I was using my OWC 300gb external hard drive for a while and it's worked great. I had a bunch of files on it, but I recently transferred everything to another external HD I have, which worked fine, so I could erase this 300gb one. I can't remember what happened, but somehow my Macbook doesn't recognize this hard drive. I think erased everything and then unplugged it without ejecting it first. Anyways, nothing is on the the drive anymore and I get this error message:
    "The disk you inserted was not readable by your computer"
    This pops up when I restart my Macbook. When I try to use Disk Utility, it greys everything out on the partition and Disk Repair tabs. On the 'Erase' tab, it will allow me to select Erase, but then gives me the error:
    "Input/Output error"
    Does anyone know how to get my Macbook to see my drive (so I can start to partition it)? For some reason only Disk Utility acknowledges it's there, Finder won't.
    Anyone have any tips of what it is or what I can try? I did try to use my OS discs booting up holding C, but that doesn't work either.

    Hi there. Everyone is saying on these forums that the hard drive is failing...suck. I went and bought a new when I got input/output error and found that the new one showed the same input output error, making it impossible to partition the disk. Then the guy in the apple service center told me the new one was bad too, after having seen the code that came up related to my new scorpio 250 GB drive. Instead of sending it back, I took it out and installed the old one..however this time with a slihtly more of pressure on the tape holding down the hard drive cable between the hard drive and the circuit board. Amazingly, this time it didn't even show any hard drive at all! Then I understood what was wrong. It was exactly what was indicated an "input/output errror"! ..the cable was broken. I bought a new cable, well the Powerbookmedic sold it as new but it was an old working one that arrived. Immediately, after change of cable the old hard drive and now also the new 250 GB works perfectly! I remember that some interesting symptoms prior to all hard drive problems appeared, such as not being able to start up properly, strange blue screens, flipping question marks etc. I remember that shaking the comp occasionally worked to get it going. No wonder, shaking occasionally made it work and i believe the damaged cable maybe changed position and started conducting. The cable is very sensitive and probably should not be taped down so hard as the first service center guy at apple had done with mine when he fixed it the comp a few years ago. Polymers/plastics bent heavily become fragile/brittle with time and are specially sensitive under pressure/bent. Note that my old damaged cable still conducted and showed the hard drives but didn't work fully. I hope this will help someone, it took me 2 month to figure out..

  • Help -- backup data with disk utility, input/output error.

    My problem started when my MacBook Pro computer (with OsX) froze.  When I restarted, the startup screen stayed on for a long time.  Now, the startup screen stays on for a few seconds and then shuts off.  I do NOT have a recent backup of my data.  I have tried the following:
    Went onto the recovery partition, used Disk Utility.  When I verified the disk, it said it needed repair.  When I tried to repair the disk, it said it could not be repaired.
    I then tried to copy a disk image of the hard drive onto my external hard drive, but it says there is an "input/output error" and won't allow it.  How else can I backup files on my computer at this point?

  • Hi, I have a hard disk failure so to recover my data I am using disk utility to restore the data on an external drive while booting from a second external hard drive. When I perform the operation it gives me an input/output error and stops. Any tips?

    Hi, I have a hard disk failure so to recover my data I am using disk utility to restore the data on an external drive while booting from a second external hard drive. When I perform the operation and after having selected both my destination and source drives, the operation begins but soon fails due to input/output error. If I try to create an image of the drive it gives me the same error message. Any help would be much appreciated.

    Disk Utility only creates a image of the drive, so it's no help getting exactly what you want, which is your files. If the file structure is messed up or the drive is failing then it's no help.
    If you have a external boot drive and you can't access the internal non-booting drive though the typical Finder and windows to transfer your files via drag and drop methods, then you need to install Data Rescue on the external boot drive and it will do as best as it can to recover your files. (works on non-encrypted/non-Filevaulted drives only)
    .Create a data recovery/undelete external boot drive
    Are you sure you have hard drive failure, or that OS X isn't merely not booting?
    Because if the drive is working physically, then there is a host of fixes

  • Disk utility 'input/output error' message?

    I am "creating an image" of a DVD using disk utility (prior to making a copy on a blank DVD disk).   Why am I now rec'ing an 'input/output error' message?   I have already copied several other DVDs from the same author (with her permission, they are not copywrited.) w/o a problem.
    What's going on?  original damaged? an incorrect step on my part?  some sort of space problem?  ( I have tons of room on my iMac.)
    Thanks for your help.

    Take a look at Cinematize 2, I've used it with iMovie 06 and iDVD 08. It has several modes of converting the data. One mode is called "lossless".
    For the job you're doing you may prefer to use iMovie 06 instead of iMovie 08 (I would).
    iMovie 06 and iDVD 08 is a terrific combination.
    Your workflow would go something like this.
    Use Cinematize 2 to create a Quicktime file from the DVD.

    Important that file into iMovie 06.
    From iMovie 06, share to iDVD 08 (assuming you want a DVD).

  • Unable to create "filename.cdr". (Input/output error)

    I am trying to create an ISO from a CD. I've tried using Disk Utility, with all different settings, and Terminal. Additionally, I attempted to make the ISO using an array of third party CD-rippers on a PC. Every platform and method has yielded this error message:
    Unable to create "filename.cdr". (Input/output error) after several seconds of processing.
    I am stuck. The only thing I can think of is that the CD is read-only, though I don't know how to modify my approach in response to this. Can it still be done with a read-only disk? If so, any help in this would be appreciated.
    Beyond that, the disk's format is ISO 9660 (Rockridge). I don't know of any other details to provide, but gladly will if anyone can come up with any.

    Use Toast:

  • [Solved] CUPS: Unable to write print data: Input/output error

    I'm filling this for the benefit of those poor googlers that can reach here.
    Symptoms: After trying to print a "complex" image the printer made too much breaks, and failed.
    The problem is, it then didn't came up. I mean, I restarted the printer, cupsd, the whole system, and nothing.
    I was unable to print again, it showed "Unable to write print data: Input/output error" and refused to print anything.
    I then saw that in /etc/cups I had printers.conf and printers.conf.O files, which differed (other than in StateTime), that printers.conf.O had
    State Idle
    but printers.conf had:
    State Stopped
    StateMessage Unable to write print data: Input/output error
    Reason paused
    Probably due to the ErrorPolicy being stop-printer.
    So seeing I followed the following steps:
    Stop cups
    Replace printers.conf with printers.conf.O (I could also had manually edited it)
    Start cups
    It then went working flawlessly.
    There was probably an option in the web interface combobox for doing that. The problem is that I didn't realise it was stopped, so didn't know how to make it work. Moreover, some posts in the web recommended reinstalling the printer (which would skip the problem by creating a new printer).

    I think that I had this same problem, and fixed it by reinstalling the printer.  Thank you for your post.

  • MacBook Disk Utility: "Input/Output Error" When Backing up my iBook

    Alright, here's the skinny:
    I'm backing up an iBook's system drive while in Target Disk Mode via my MacBook using DiskUtility. The drive I'm saving the image to is an HFS+ USB 2.0 enclosed standard 3.5" drive. I start the process and things go just fine--
    --but then!
    "The device you removed was not properly put away. Data might have been lost or damaged. Before you unplug your device, you must first select its icon in the Finder and choose Eject from the File menu."
    So yeah, about five minutes into the backup, I get one of those lovely "Device Removal" notices, even though I haven't touched anything and no drive has gone unmoutned in Finder (or in /Volumes/). After this I get a plain jane "Input/Output Error" message and am left in the dark.
    Here's what I've tried:
    -Restarting, killing every unrelated user-level process
    -Disconnecting every other device, media, and peripheral from both machines
    -Running the machine in "Better Energy Savings" mode and disconnecting the PSU in case FW or USB was fritzing from the 83C of heat the computer was causing.
    Alright. Somebody help.
