Problem Removing Files: Input/Output Error

I recently posted this article
http://discussions.apple.com/thread.jspa?messageID=4596969#4596969
about my struggles to repair my hard drive. I'm currently in Single-User Mode, in the process of manually removing files that returned the error "Overlapped Extent Allocation" during fsck. Everything's going well for the most part, but a few of the files I'm finding can't be removed. When I try, I receive this message:
hfs: WARNING - blocks on volume Garfunkel not allocated!
rm: [path name]: Input/output error
It all sounds very dire and life-threatening, but I have no idea what this means. I can only assume it means there is a permissions issue. Am I close? Is there a way I can remove these files? So far all of the files have been iCalendar files or iApps preference files. If it's important, I can list the exact files. I hope someone can help me, because I know very little about Unix.
Thanks to everyone who makes an attempt at rescuing me!

Thanks. I did that, as per the Apple Support article instructions, but apparently I have to do it before every remove command. And sometimes, I have to input the command twice for it to work. Thanks for the tip.

Try to mount a dmg file -- Input/Output error

I have certainly searched thru postings, but I cannot quite find a solution.
[1] An external FireWire drive holds a lot of dmg files of application installers.
[2] Double-clicking some, not all, of them results in an Input/Output error.
[3] Toast is always able to mount them.
[4] When the error happens, an attempt to copy the dmg file onto the Desktop results in another error message "The Finder cannot complete the operation because some data in "<name>.dmg" could not be read or written. (Error code -365)". At this point, clicking on OK brings up a Copy window which hangs. The only way out is to Force-Quit the FInder.
What should I do to rectify these issues?

I appreciate your suggestions.
The external drive in question is OWC's Mercury Elite-AL Pro with FireWire 800 (2) and 400 (1) ports
It was purchased in February, 2008. Its original connection was thru FireWire 800 to my G5 Tower.
[1] Ports
      The G5 has only one FireWire 800 port, while the OWC enclosure has two.
      So, I used the other FireWire 800 port on the OWC.
      The same intermittent I/O error in mounting dmg files.
[2] Cables
      I tried another FireWire 800 cable with either of the two FireWire 800 ports on the OWC.
      The same intermittent I/O error in mounting dmg files.
      So, I switched the connection to FireWire 400 between my G5 and the OWC.
      No I/O errors after trying to mount numerous dmg files.
[3] MacBook Pro
      I disconnected the OWC and connected it to a MacBook Pro's FireWire 800 port.
      No I/O errors after trying to mount numerous dmg files.
From [1], [2], and [3] above, can I deduce that something is wrong with the FireWire 800 port on my G5 Tower? I thought that both FireWire 800 and 400 ports on the G5 Tower were controlled by the same chip.
Please advise.

SOLVED: Getting an Input/Output error when accessing certain files

My system started failing a few days ago because of sudden Input/Output errors when trying to access certain files. It was running fine until various applications started crashing like for example Pidgin (in retrospect probably because of DBus crashing). I decided to reboot and now can't login anymore because the DBus module fails to load which in turn means that HAL doesn't load either and so I can't use my keyboard to login.
The error message I get from DBus is that it can't access the file /etc/dbus-1/system.d/org.freedesktop.PolicyKit.conf because of an Input/Output error. I tried to fix/see what was wrong using the arch livecd. Because I thought my problem had to do with a pacman update that had failed before I'd rebooted, I updated my system and I noticed that when pacman tried to access other files it came back with the same error message. The files seemed pretty random, one of them was fakeroot.conf and then several library files like libfaad (sorry this is kind of vague but I'm away from home right now and can't go online very often so I'm writing this from memory).
I'm guessing its a hard drive problem because checking the filesystem for errors came back with nothing. I was just wondering whether anyone had any other ideas before I go and reinstall. I'm going back home tomorrow so I'll be able to follow any advice/reinstall then.

UPDATE
It seems to be fixed! The second run of e2fsck fixed some more issues and the files that were causing the problems earlier seemed to have bad inodes. Boots fine now and I can get into my system. I checked and I still have a reasonable amount of free space so I don't think that was the reason ... I have no idea how the filesystem got so corrupted out of nowhere.
A few things are different, for example, it asked me to unlock the keyring and I couldn't mount my external encrypted drive anymore and had to do it manually with cryptsetup. e2fsck made quite a few changes so I imagine it's due to that. Shouldn't be to hard to fix though.
Thanks for your help!

Failed to execute default file manager (Input /Output Error) [SOLVED]

I'm having an issue in XFCE where the default Terminal, Browser and File Manager launch correctly - but with this error:
Failed to execute default [file manager] [terminal emulator] [browser]
Input /Output Error
I have the requisite "Preferred Application" set as Chrome/Thunar/xfce4-terminal.
If I run
exo-open --launch FileManager
From terminal, it says:
[1] 4281 segmentation fault (core dumped) exo-open --launch FileManager
Remember, it launches the app successfully - and the apps themselves launch correctly, it's only exo-open that I have a problem with! Everything else works great on this system.

Tried downgrading glibc from 2.21-3 to 2.21-2 as this is the package which contains libpthread.so, and on my other arch workstations I don't have the issue, but to no avail, same error box pops up when using exo-open, and my IDEs are not starting.
I'll try comparing installed packages versions on both workstations.

.dmg problem input/output error

hi,
i have a copy of adobe cs3 from my college, and i am having problems installing. i skipped the verification. and then i noticed it would only install about 3 components, not illus. photoshop, or flash, then i let the verify run, and then it came up with an error of "input/output error" how is it possible to save the files on the dvd, what are my options?
also, another sidenote, i have had a weird problem with i tunes, since 7.6.2 and my software is all up to date. if i run i tunes, it could be 10 secs or after about 10 mins. the pinwheel comes up and wont go away, how can i check in system monitor if theres somehting fishy, has anyone heard of this problem ? i was thinking to downgrade since i have not had problems until i upgraded

HI Gene,
"This usually works fine but now and then I get an error that says " Unable to create disk1s10.dmg Input/output error." Have you downloaded and installed any 3rd party software or changed any preference files since you've successfully done this before ??
If your profile is correct, you might try updating from 10.4.8 to 10.4.11. If you do, make sure and Repair Disk Permissions when it's finished.

Nvidia Input/Output error. Could not open the device file /dev/nvidia0

Hello, I finally have Arch running on my MacBook pro 3,1 (mid 2007) but when I startx after installing Nvidia drivers it gives the Input/Output error and states "could not open device file /dev/nvidia0." I tried everything from the Nvidia wiki, and nothing seems to work. Does anyone please have any other ideas or things to try? My Nvidia card is 8600M GT and I have installed xorg-server, xorg-apps and Nvidia-utils already. Also is it possible my graphics card is not compatiable with this new kernel? Thank you for your time.

You know that this posts a huge list - and I couldnt remember how to trim for certain keywords (which one would you be interested in?).
So here the last few things regarding Video: from dmesg:
[..] nvidia: module license "NVIDIA" taints kernel.
[..] Disabling lock debugging due to kernel taint.
[..] nvidia 0000:01:00.0: enabling device (0002 -> 0003)

I am not sure it is arch fault, but since I don't think I have a disk problem (dmesg doesn't show errors), I thought that maybe there was a problem with the packages or something else ...
I tried to remove these files and reinstall the package, but I can't (rm show me the Input/output error).
Thanks

You were right, there was a problem with the filesystem (there was no badblock, I checked, so I guess (hope) it was only logical).
Got a bunch of errors about flag that should not be set (extend, compress) and size that should not be good, and also errors on the files I mentioned above.
I reinstalled the corresponding package and I did not got the errors I was getting before.
So I guess (hope again :) that all is alright now.
Thank you !

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.

Input/output error when copying a DVD

I created A DVD some time ago using Roxio. It plays in DVD Player on my Mac Pro, but I can't create a .dmg using Disk Utility. I always get "Input/Output error". I got the same result on my wife's newer Apple. I tried to Restore it but can't, and Verification shows no problems that I can see. I am able to copy DVDs created on Final Cut Express just fine. Any suggestions to help me create copies of an old DVD I love?

I just figured out how to get around the problem. Download Burn and use it to burn the VIDEO_TS file to a new disk. It must be something that Apple adds to make it hard to copy DVDs made from non-Apple software.

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..
