Error when verifying hard drive

I restarted a "snow" iMac (OS 10.2.8•256MB RAM•600 MHz• G3) with the system disc and verified/repaired permissions. I then tried to verify the hard drive and the following message appeared:
"The disk hard drive failed to unmount because it is in use. The operation has been cancelled."
What does this mean and how can I verify the hard drive?

No. You need to use a bootable installer disc for the same major version as the installed OS (e.g., if you have 10.3.x installed then use any Panther installer disc.) An upgrade disc can only boot a computer that has an earlier version of OS X installed. A Jaguar upgrade disc can only boot a computer with 10.1.x installed.

Invalid node structure error when verifying hard disk, please help

My 27" Mid 2011 iMac is having hard disk issues. I attempted to repair the disk but received an error that said the disk cannot be repaired and needs to be re-formatted. I have all my files backed up to an external hard drive so I erased and formatted the disk. After reformatting, I ran the verify disk function and got the message saying the HD appears to working properly. I reload OSX Lion and within a day, my computer freezes up and acts as if something is wrong. When I run the verify disk, I get the Invalid Node Structure error multiple times and then the message saying the disk cannot be repaired and I need to reformat the drive. I have completed this process several times and have had no luck. I have looked at a few forums with people who have had somewhat similar problems but am still unsure. I have seen people recommend programs like Disk Warrior to repair issues the hard disk utility cannot but I don't want to spend $100 dollars on this program if my hard disk is damaged and needs to be replaced. Any suggestions? Thank you

Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Execution Errors when duplicating Hard Drive on external HD....

Hello
I've got an Iomega Firewire portable HD, I wanted to duplicate my iMac Hard Drive so that I can free up some memory and use it as a back up. I know there are lots of backup software programmes out there but I installed and used the Retrospect Express programme that came with the portable HD.
I followed the instructions, left it dupliacting overnight and it all seems to have worked lovely but I had a window open this morning titled 'Execution Errors'. It said there were 5 errors during duplication and lists some folders & files:
MacHD>Library>Caches root/admin
com.apple.LaunchServices-0140.csstore
com.apple.LaunchServices-014501.csstore
private>var>db root/wheel
.dashboardadvisory.database
dashboardadvisory.database
run root/daemon
ntp.drift
Please help?! Does this all mean anything significant?
Should I be concerned about the duplication that I've done and is it safe to trash files from my iMac HD now I have the duplicated version on my Portable HD?
Thanks and best wishes

Thanks.
I verified the HD (while booted from it) and it didn't tell me to do anything, I think it was fine [sorry to sound so dumb, I should have written the results down] it said it was okay so I assumed any errors had been corrected without me having to address them. Then I verified permissions, again this seemed to go okay, response was alright and didn't tell me to do anything.
I ran the duplicate procedure agin overnight, having re-partioned my external hard drive.
I had tried this twice before over the weekend and received the same 5 Execution Errors both times.
This morning I have checked and it has duplicated the HD onto my external okay but I have 16 Execution Errors. I have found them in the Operations log and pasted them below. A lot of them seem to be discrepencies between data size or creation date/time between 'src' and 'dest'.
Would 'src' be my iMac?
If anyone can help identify what the errors mean and if there are implications for the data I have backed up I'd be very grateful!

How to know when a hard drive has failed ?

Machine doesn't boot. You experience strange crashes. Gets wrong results. Your harddrive is five or more years old. Time to consider repacing it.   You do have backup?
You may want to run these "standard" fixes if the problem persists.
1) Check the amount of free space on your harddrive. You should have a several gigs free.
2) You should run disk utility
     a) verify the disk
     b) update your permissions.
3) Try a safe boot.
    Shutdown your machine. Hold down the shift key. Poweron. Wait awhile Wait awhile while you harddrive
      is being checked.

verify & repair your startup drive
To verify & repair you file system on the startup drive, you will need to run disk utility from you installation DVD.
This article will tell you how to get to disk utility. Once in a disk utility, you can go and attempt to recover the disk.
http://support.apple.com/kb/TS1417
To repair your startup drive, you will need to run disk utility from your startup DVD.
Mac OS X 10.4: About the utilities available on the Mac OS X 10.4 Install DVD
http://support.apple.com/kb/HT2055
How to run disk utility from your startup DVD.
Insert your startup DVD into your reader. Power down your machine. Hold down to the c key. Power on your machine. This will bootup your startup DVD.
This will bring you to a panel asking you for your language. Pick your language.
You you come to the Install Mac OS panel. Do not install.
Click on Utilities menu item. This will give you a pulldown list of utilities.
Click on the disk utility.
You are now in disk utility. Pick your disk. Click on repair it should be on the lower right of the panel.
Once the repair completes successfully, you should update your permissions.
Verify a disk
As an alternative, you can verify that the filesystem on the disk is correct. You will not be able to repair the file system.
I suggest that you use disk utility to verify that your startup disk is OK.
Macintosh-HD -> Applications -> Utilities -> Disk Utility
Start up disk utility. On the left pane view, you will see a list of all your disks.
Click on your startup disk.
Click on the First Aid Tab.
Click on verify.
Hopefully your disk will verify. If not, you have to boot from your installation DVD and run Disk Utility from there to attempt to repair your file-system.

After trying to install Mavericks, got an error message my hard drive was bad.

After trying to install Mavericks, got an error message my hard drive was bad. Took it in to the Apple Store and the 'Genius' bar guy couldn't see it as an external drive when he connected another Macbook. If I get another hard drive what's involved in getting my system operational again?

Hi there
Looks like I may be experiencing a similar issue to yours as having issues installing Maverick on snow leopard?

Weird Error When Verifying External HDDs

Hello
I'm getting a weird error when verifying my 2 external HDDs. Both give me an "invalid leaf record count" error. But only when I check them with the OSX install cd. If I check them in my user account, they come up OK. Both drives also gave me a "reserved fields in the catalog record have incorrect data" error. Disk Utility was able to fix that error, but not the invalid leaf error. I have tried multiple repairs, but DU says the volume cannot be repaired. The other weird thing is when I ran the first repair, it said 1 HFS Volume Repaired and 1 Volume could not be repaired. I have also tried using Disk Warrior, but it gives a "this volume appears to be formatted with a newer version of the OS" error.
Both these drives I had plugged into my mom's iMac (running 10.5--my eMac is running 10.3.9) because I had firewire problems back in June. Did 10.5 modify something that has 10.3 mixed up?
Is there something I can do to fix this or do I need to do another re-install?

"+I hear her playing music+..." ~ Barry Manilow

OS X 10.5 does add additional attributes bits to the file descriptors, so using the drive under 10.5 would be expected to add those additional bits to at least the disk directory plus any modified files.
When you then check the drives using utilities created prior to OS X 10.5, those older utilities don't understand the additional bits and report then as errors (DU), of the utilities check first and refuse to run if the disk is tagged as from a latter OS version (DW).
There's a generic warning about mixing older utilities with newer OS versions in Only use Mac OS X 10.4-compatible disk utilities with Mac OS X 10.4 volumes.
I'd be ready to shrug the error reports off as spurious; however, that DU "corrected" the reserved bits suggests the drive directories will be rewritten again should you again move the drives to a 10.5 computer. Are you seeing any actual problems wiuth reading or writing to the external drives? If not, write it off to 10.5 settings bits that earlier versions ignore; it shouldn't affect your data.

I lost my iTunes library on my pc when the hard drive crashed. None of the data on the drive was recoverable and I did not have a backup. How can I get the music that resides on my ipod nano (4th generation back onto the new hard drive on my pc.

I lost my iTunes library on my pc when the hard drive crashed. None of the data on the drive was recoverable and I did not have a backup either locally or on the cloud. Much of the music is from old vinyl and podcasts which are no longer available.

I have been reluctant to install iTunes on the new hard drive out of fear that I will lose all the contents on the ipod if I try to synch to the new hard drive.
Help!

No backup is a huge mistake.
You can redownload some itunes purchases in some countries:

Copy all the content on your iPod back to your PC and into iTunes. Then go ahead and sync the iPod with your new library.

I lost all my purchased songs when my hard drive. Can I get another copy from Apple?

Quite possibly, at least assuming you are based in the US. Install the latest build of iTunes, sign into the iTunes Store and click the Purchased entry in the Quck Links panel. Here in the UK I only get tabs fro Apps and Books but, if I understand correctly, you should also get a tab for Music. Click on the Not in My Library button and you should be able to download your purchases again.

?When your hard drive crashes

I had about 400 compact discs and a few itunes worth of music on my itunes when my hard drive crashed.
My music is still on my ipod but it seems if I put anything on my new itunes folder on my new hard drive, I'll lose my old music when I sync.
Is this correct?
I'd appreciate any help on how to live with this lost data on my hard drive.

Hi. Welcome to the forums.
Yes, Your new install will want to overwrite the iPod with a blank library given half a chance. Check out this post from Zevoneer for some iPod recovery options.
http://discussions.apple.com/thread.jspa?messageID=6273675&#6273675
Should explain how you can drag your music back from the iPod. I've used the manual method successfully in the past. Some of the other tools can take a long time to catalogue the iPod so be patient.

Ipod makes weird sounds when the hard drive runs

my ipod video is making weird click clak sound when the hard drive starts running. Is this normal?? HAs this happen to anyone before?

HEY!!!!!! I wasnt alone. Amazing. I had the same experience with my new Black 30 Gig iPod 5 Gen. It had a 3 second delay, made lots of HD clicking noises. And worse after a few hours of usage, forgot 240 of my 270 songs that had been transferred onto it. This was all happening on the first day! Wow.
Im sure glad to hear I was not alone. The sad thing is, Amazon is going to take 4 weeks to return my money to me. I will never again by a hardware product from Amazon.com. It simply takes too long. As far as Apple iPods are concerned, I believe they need alot of design renovation to put it frankly. Here are my complaints about the 5 Gen:
1. No Screen Brightness Controls. A major no no.
2. 3 Second Gaps between songs. What?
3. The trackpad on the iPod is far out of alignment. Not sure who supplied these, but the Mini was far superior to the 5 Gen trackpad. The traction was severly off kilter.
4. 284$ for an iPod that forgets 240 songs in a blink of an eye? I don't think so Apple. Get a grip. Woz was correct when he stated you all use crapy supplies for your parts.
I thought he was kidding?!
This was my first and by my choice, last iPod experience to be had with Apple. They are cute, but software/user level wise, they need alot of work.
