Input/Output Error

After having some progressive troubles with my Powerbook laptop I went and decided to erase the data and start fresh.
After going through the seven pass erase and waiting for close to four hours I just got a message stating that "Disk Erase Failed with the error: Input/Output Error."
Suggestions?
Thoughts?
Thanks

Open Disk Utility, select your hard drive in the left pane (the line continaing the drive manufacturer's name and model number), click the First Aid tab, and check the drive's SMART status near the bottom of the DU window. If it is Failing, replace the drive.

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.

I am in mavericks disk utility recovery mode as my mac book will not boot up & stays only on the grey apple screen. When I verify the disk I get open error5 :input /output error on Syst stuck on 1 minute pouring out over 50 error messages & still counting

I am in Mavericks disk utility recovery mode as my mac book pro will not boot up & stays on the Apple grey screen . When I verify disk permissions I get
Open error 5:"input/ output error" on syst with over 50 of this messages & still counting . Disk Utility says 1 minute
But this has been going on for over 10 mins .
I can not verify disk or repair disk .
I have tried to reinstall mavericks operating system but it says my hard drive is locked which is very strange .
Does anyone know what is going on here ?
My system looks like it has been totally corrupted . Thanks Andrew

Could be. The "lock" isn't actually looking for a password.
WARNING: This will completely erase the ENTIRE hard drive.
What you would need to do is boot to recovery > disk utility > select the MAIN drive on the left side > partition > change partition layout from CURRENT to 1 PARTITION > ensure on the right side it says Format : Mac OSX Extended (Journaled) then push APPLY.
Then if it will allow us, close the windows until you see the 4 options popup again and select "Reinstall Mac OS X" select the Mac HD and you should be good to go!

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.

"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.

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..

External HD - Input/Output Error

I had external drive that was not mounting or appearing on Disk Utility. The drive was out of warranty so I went ahead and changed the casing.
1.The drive appears on Disk Utility but still does not mount. DU only shows the root and not the volume.
2.Connecting it via USB tells me the drive is 298GB and appears as Maxtor 5000DV v0.1.00.00 Media. I connect it via Firewire 400 and it DU shows it as 128GB Maxtor.
Any help on what's going on here? DU also won't let me First Aid, Erase, or anything else on it. After I try to Erase it,Partition it, or anything it gives me "Input/Output Error".
10.5.2
Maxtor External (Actually a Seagate inside)
G5
Thanks for any help!

Adding:
What is the point of "Restore" and how is it used exactly?
Thanks!

External Drive Disk Erase Failed with the Error Input/Output Error

I have 2 hard drives in an external FW800 enclosure that I am unable to format. When I go to initialize the drives in Disk Utility, I get the following error message: "Disk Erase failed with the error: Input/output error."
The drives show up in Disk Utility, but I can't repair them (that option is grayed out). Disk Utility correctly ID's the manufacturer of the drives (Maxtor), their size (200gb each), so it's obviously seeing that the drives are there. But it won't let me format them.
The drives are new, by the way; they don't have any data/files on them. I have Disk Warrior, but the drives don't show up there to be repaired -- probably because they aren't formatted yet.
After looking at other posts, I tried switching the jumper settings around on the drives -- from Master/Slave to cable select and back again, but it didn't help. I also tried doing a zero erase (even though the drives are new), zapping the PRAM -- again, no help.
One question I had is whether this could be a bad FW800 cable? The cable is new -- it came with the enclosure, which is an OWC Dual FW 800 enclosure. Other than that, does anyone have any other thoughts about what's causing this? Any help would be greatly appreciated.
Matthew

SOLUTION!!!!
I had the exact same problem. I have the original 20 GB hard drive that came in my Powerbook G4 550MHz and a couple of years ago I traded up for a 60 GB drive and bought a FW/USB enclosure for my original drive to use it to backup my important files. I hadn't backed up in over a year (shame on me!) and I decided maybe I should erase the drive and start from scratch. It was connected via USB.
At that point DiskUtility gave me the exact same Input/Output error. I tried partitioning the drive into 1 or more partitions but came up with the same error. I couldn't figure out what was wrong so I decided to startup in OS 9.2.2, I did that and let it start up, then plugged in the hard drive and it gave me the standard "This disk is unrecognizable, do you want to eject or erase?" so I clicked Initalize. It worked!
Just make sure you choose the MacOS Extended option when initializing out of OS 9 (instead of the MacOS Standard option) so it can be read and viewed in OS X.
If your computer is too new to be able to boot from an OS 9 folder on your drive or an OS 9 CD, then see if a friend or a local library has older computers that are running OS 9 or can boot from it. If not let me know and you can send me your drive and I'll reformat it.
Kind of crazy...I haven't used the OS 9 partition on my HD in YEARS...was even thinking about erasing it since I don't use any Classic applications anymore...good thing I didn't!

Can't acces to internal laptop hard disc - input/output error

Sometimes when I use my i can't acces to any file on my hdd and i get input/output error when i type commands in console(i even can't halt or reboot). This is used to happen suddenly after few hour of work in one session (not always, it happend three times during last week)
When i get this error the hdd control led is on (I have ibm x60s with ssd hard disc, and normaly this diod only blink sometimes, bbut when i get this error , diod is the whole time floodlite. I didn't any similar problem in google so i posted it here.

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,...).

Hard Drive "Input Output" Error When Attempting to Format

A friend just gave me a nice PowerBook that seems to be in need of a fresh OS and when attempting to format the hard drive I am getting an "Input Output" error. Any suggestions to overcome this issue and format the drive?

Hi all,
I'm having similar issues on a white macbook (2006 model). I ran into some trouble with it about a month ago, when on booting up, it showed only the folder with a question mark. Booting up from the original grey install DVD worked, so I thought the problem was most likely a faulty hard drive.
It's only after having this problem, that I came across this recall for possible faulty hard drives, that Apple offered:
http://www.apple.com/support/macbook/hd/repairextension/
Doh! Too late?
So, I got onto ebay and picked up a deal and received my new hard drive yesterday. I swapped out the original 80GB with 320GB, only to find the same input/output error described by the OP, here (also in a couple of other Apple discussion posts - see below).
Disk utility shows the new hard drive to be 2.3TB in size! Should be 320GB - but, this is also what others have described. See e.g.,:
https://discussions.apple.com/message/16090313#16090313
I've run the extended testing from the CD (holding down 'D' on boot-up) and it reported no problems. Also, similar to others experiences:
https://discussions.apple.com/message/16081818#16081818
So, what can the problem be?!?!?!?!?
In this post, JMPC suggests it has something to do with the size of the new internal hard drive....groan.....:

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?

Had issue partitioning 2TB my passport drive, got input/output error while using disk utility.
Here is what I did to get my external disk back
In Disk Utility
1) Try to use erase option first, it failed
2) Try to partition the disk, failed as well.
3) Then try erase option again, then ... it worked !!

Disk Utility "Input - Output error" when attempting to erase Hard Drive

Hope that someone can point me in the right direction.
I bought an external hard drive for Windows a year back and loaded music onto it. I realized that I my MAC wasn't getting "Read / Write" privileges for the External Hard Drive, so I decided to try to Partition it and make it into a FAT readable device. It erased all data from my hard drive, but Disk Utility stopped the process and displayed an "input - output error".
Consequently, I can't initialize the external hard drive to make it usable on my MAC.
Can anyone point me in the right direction so I can "reformat" my external?
Thanks!

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?

WD External Hard Drive will not format, "Input/Output Error"

Trying to reformat an old Western Digital external drive, immediate error in Disk Utility "Input/Output Error". Switched USB cords/ports, nothing. Just getting a second opinion before I trash it.
I know I can probably take out the drive and put it in an external case, but this was just going to be an extra drive for a friend, not worth the $20 for the case.
Thanks

I'm getting the same errors from both my USB ports when I try to format a brand new Maxtor 1TB drive.
I had noticed some strange errors a week ago when Time Machine was reporting an error saying it had failed (this was using a nother external firewire drive). Errors were (not verbatim) "error writing files" & "unknown error".
I naturally thought there was a prob with the ext drive, so knowing that I had at least a good full back-up on there, bought a new ext drive (larger) to perform a full backup on so I could reformat the firewire drive and utilise it elsewhere - but got errors when I tried to set it up as a Time Machine drive seconds after I took it out of the box.
I ran "Verify Disk" on my internal macbook HD and it reported some permission errors and mis-reported file sizes and told me to "Repair Disk". I did, and this stated it fixed a few things. Ran Verify again and it still reported some permission errors.
Now, this leaves me in a sticky spot. I can't format the maxtor external disk in order to manually copy over my disk content, it doesn't even show up in disk Utility or in Finder. I can't perform a Time Machine backup - as it can't see the maxtor disk. I can't do a TM backup on the old Firewire disk - due to the program errors. AND it appears I have permission errors on my internal HD.
Whatever course of action I take to correct these problems - I would like the knowledge that I have a full backup to restore from if things "head south" while I look to correct the HD permission issues.
Anyone out there with some REAL SMART ideas that can help me out here ?
Right now I'll even accept "Half Smart", "Clever" and "**** - Why Didn't I Think Of That" answers !
