Tim.PaperHouse Level 1 (0 points) Q: Power Mac G5 with disk0s3: I/O error I have an old Power Mac G5 that just started freezing on start up. It gets to the gray screen but just spins and after about 5 mac disk1 i/o error minutes the fan kicks into high as it continues to spin. Here's what I've done so
Error 0xe00002ca Detected For Lvg
far: • Tried starting up in safe boot and got a Kernel Panic• Tried booting from installation disk (which was succesful) and verifying the disk
Disk Io Error Mac
through Disk Utility which failed, giving me the following message "invalid node structure - the volume needs to be repaired. Error: The underlying task reported failure on exit, 1HFS volume checked - volume needs repair"• Tried to repair disk through Disk Utility
Disk0s2 I/o Error Fix
which failed, giving me the following message "invalid sibling link - volume check failed - Error: The underlying task reported failure on exit, 1HFS volume checked - volume needs repair"• Tried booting in verbose mode which repeatedly gave the message "disk0s3: I/O error"• Tried booting in verbose mode again which repeatedly gave a different message "MDNSResponder ERROR: getOptRdate - unknown opt 4"So… I'm assuming it's pretty bad. Can anyone tell me what these errors mean and if they specify what is wrong (hard disk, the volume macintosh hd could not be verified completely logic board, etc)?Thanks in advanceTim PowerMac, Mac OS X (10.4.11) Posted on Aug 22, 2012 10:45 AM I have this question too by japamac,Solvedanswer japamac Level 7 (24,390 points) A: Do you think I could pull that hard drive and install it in the first?As long as the OS is of the proper version (not older than the G5), then it should be no problem at all.It does sound as if your drive has completely failed........

Make sure the hard drive is formatted on your Mac by booting from an installer disc that supports your Mac, if you have no data on the drive you wish to preserve. If there is data on the drive you wish to preserve, was it on an Intel Mac before? Cause Intel Mac formatted drives will not work directly on a PowerMac. They will network with them, but the software may not run, and worse the GUID formatting that defaults on an Intel Mac can't be used on a PowerMac.

Have you tried booting to your operating system disk? If you can boot to the OS goto utilities/disk repair and run disk repair until it reports no trouble found.

Miniguide to fixing Volume-Filesystem errors Apr 29, '11 07:30:00AM • Contributed by: santa97298 There are many drive/filesystem errors that can occur on a Mac. Here are some common symptoms that are indicative of some of them: Not able to boot http://hints.macworld.com/article.php?story=20110216112523818 the system: You tried to boot. Apple logo appeared, and wheel spun for about 15-20 http://www.insanelymac.com/forum/topic/268860-repeated-disk-io-error-after-waiting-for-dsmos/ seconds, then machine turned off. This repeated every time you tried to boot the system. (REASON: The system does not find your HD and thus the OS to boot). Everything seems to work fine till your system hangs briefly and in an unpredictable way. You wait for a while, and the system magically comes back to normal. But after i/o error another while, the same thing re-occurs! (This cycle repeats in the current session). You can do these simple things to check for other possible causes: Run Activity Monitor to see that this is NOT due to temporarily high CPU and/or Memory usage. Check the system log using Console.app or running tail -f /var/log/system.log in Terminal. If your system is having some I/O error then it is sure that there is an HD failure issue. I disk0s3 i/o error don't claim to be an expert on this subject matter, just an (over)enthusiast Mac user. This guide is purely based on my personal experience and is bound to contain errors. So, USE IT AT YOUR OWN RISK! [crarko adds: Consider this hint to also serve as a reminder to check your backups...]Possible problems: Your HD Volume/FileSystem is corrupted Verification: Use Disk Utility and run "verify" to check it. 2. Your HD is dying. Verification: Use Disk Utility and see the SMART status of your HD, although this isn't always reliable. Before making any repair of the disk, make sure that you have the latest backups. Repair might let loose the volume/filesystem info all together and then there will be no other choice than to recover the data by some data rescue s/w like Data Rescue! If you don't have a current backup, you can try booting in Single-User mode by holding Command+S on startup. Then try doing a manual backup using commandline tools like cp or ditto. Note: The disk usually gets mounted in read-only. This could be good to get a manual backup by cp. But if everything else fails and you want to remove the important/personal data before sending it to repair, you can try mounting it in the write mode by this: mount -uw / It might be good to

Booting into single user mode and trying to use fcsk didn't work. I read here to try "sudo chown root:admin /", but that didn't do anything and instead just said "chown: read only" or something similar.Any ideas? I really have no idea why it broke down, I don't remember installing any updates or changing any kexts.Vexir Back to top #2 Gringo Vermelho Posted 24 September 2011 - 10:37 PM Gringo Vermelho The Jan Bird fix Supervisors 6,224 posts Gender:Male Location:Brazil Boot from your install media and use Disk Utility to do a disk repair.If that doesn't help try this: http://www.cgsecurit...g/wiki/TestDisk Back to top #3 Vexir Posted 25 September 2011 - 01:46 AM Vexir InsanelyMac Protégé Members 28 posts I must be really stupid or I'm missing something.

You have three options: 1) Make your own Chameleon boot CD and use the 'swap trick' to boot the retail DVD. Visit the VoodooProjects forum, look for a post by me and follow the link in my signature. You need to register an account to download the attached files. 2) Use Apple Disk Utility to restore your retail DVD to a partition on your hard drive. This will be bootable with
