Disk Stops, then I/O error
Okay lately i've been getting an i/o error whenever trying to access my ipod 20 gig 4g through my computer, and if u listen to it closely u can hear the disk spin up then then Clunk sound and the disk is stopped, then spins up again, after that xp returns an I/O error
Also when i play music it skips and have the time doesnt work, im getting frustrated this has happened before, but was fixed by a format, how can i fix this WITHOUT formatting?
on XP or W2K, Start->Help and Support will tell you all you need to know. If when you plug in the iPod it says it needs formatting then you don't have exactly the same problem as codex. You (first) need to either use the Apple Updater to restore the iPod (or use the XP Format command and then try the iPod Updater restore). If the iPod is not being recognised by the updater put it into forced disk mode first. With the Updater follow the instructions exactly and in particular do not attach the iPod until the Updater prompts you to do so.
Hope that helps.

My Mac OS Lion 10.7 FileVaulted HD does not boot, prohibitory sign, stop sign appears some minutes after boot starts. Disk Utility repair shows four error messages:
Unable to bootstrap transaction group 2517: inconsistent crosscheck
No valid commit checkpoint found
The volume xxxxxxxxxxxxxx(here it shows physical volume number) was found corrupt and can not be repaired.
Problems were encountered during repair of the partition map
Error: Storage system verify or repair failed.
(the same with 2518, 2519 and 2520 transaction group)
I suppose it is serious bug in Mac OS Lion managing FileVault and wonder what the help could be?Most likely culprit is your Lacie drives which are notorious for flaky power supplies which cause just the sort of erratic behaviour that you describe. Have had similar issues myself. Lacie has been good about replacing my power converter-- twice. If you have seven of them, good luck finding the bad one or more. Like I said, the behaviour is erratic. Sometimes it'll work sometimes not. I can't comment on Samsung drives because I've never used them and have never heard anything about them. Same with Softraid. Why not just use Disk Utility. Sounds like you're ready for an external hardware raid. This will be much faster, much more reliable, and may even be cheaper than seven firewire drives. Check out G Tech, and Maxx Digital for starters.
Best of luck

I just purchased the hunger games on blu-ray with digital copy. when I try to download the HD digital copy it gets to about 80% compete then stops with a download error (-50). What is that how do I fix?
Perhaps try the "Error -50," "-5000," "8003," "8008," or "-42023" section in the Specific Conditions and Alert Messages: (Mac OS X / Windows) section of the following document:

Need assistance with my Porsche Design LaCie Time Capsule... It is not operating at all.. I have ran the diagnostic via the Disk Utility and under the error reading it runs the repair and then says it not about to repair what do I do... Thanks
LaCie doesnt make ANYTHING. It contains a Seagate 3.5" 5400RPM HD.
Check the HD on another computer, if nothing, your SATA bridge is fried, or the HD (very unlikely since its a Seagate inside)
Youd have to crack open the HD, remove the SATA bridge cart thats plugged into the HD and put the HD into an enclosure or a HD dock to get the data
those external HD use a 50 cent SATA bridge famous for failing. The curse of all the good HD externals is the junk 3rd party SATA bridges attached to them that crash and burn.

Is there any way to download these files manually from another source? The download from boot camp keeps stopping at around 25% and then produces the error "Can't download Windows Support Software because of a network problem". Thx!
No. This issue is dicussed here frequently. The only option is to be patient and try often. Search this forum for other posts about this issue.

Oh, so this is where I ask my question. Sorry, first time here. As I was saying in my long intro, the gray screen come up and the thing is spinning at the bottom, but nothing happens. Then the fan starts reving up like it is about to explode and I have to manually shut it off. A friend told me to start it up with the OS disk and then go to utilities. I couldn't find the thing, so I went out and bought another. Needless to say, it didn't work. Is there a key stroke to help jump start the machine? How can I get into this thing? I would prefer not to take it in because there are a lot of things on there I don't want just anyone to have access to.Thanks, in advance, for your help!

Your drive does need to be repaired, and best things to buy are another backup recovery drive, with a small OS X partition; a copy of Disk Warrior is expensive @ $90 but excellent and best.
Never bother with or use the drive or reinstall while there are errors. Don't take a "clean' bill from Apple Disk Utility to mean there are no errors. Only that it didn't find what it looked for.

Make sure to have multiple backup sets and of your system so if there is a serious problem, you can just erase and restore to be back runninig.
Sounds like your G5 though needs PMU reset, not PRAM, and the best way for those is to clear nvram instead. might even want to check for dust; tell what System Profile says (later) as to "PowerMacX,Y" or "MacProX,1"
http://www.apple.com/support/powermac or /macpro
http://www.apple.com/support/sitemap/
The Utility menu is on the menu bar of an "OS X Install DVD" and at the point where you get to but stop at "install....' for OS X. you probably do need to install OS X on another drive to work from.
Oh, a real severe issue and damage to the drive directory or filesystem CAN in cases prevent booting from DVD (the system still tries to find and see what boot volumes are present) and can help to pull or disconnect the drive. Putting a drive in a FW case to turn on after startup is very useful. -
Verify Disk stops in Mavericks
I installed Mavericks on my 15" MBP, and it seemed to go fine (too soon to tell, really). In Disk Utility, I ran Verify Disk for the whole disk and it checked out OK. But when I tried it on my single partition (as I usually do), it stopped spontaneously. Repair Permissions worked, but Verify stopped three times: twice after "Checking Volume Information" and once after "Checking Extended Attributes File". No error message; it just stopped.
Should I be concerned about this?Same here with 10.9.4. Sometimes I see the green OK on the 3rd or 4th attempt, or and after relaunching Disk Utility and or my MacBook Pro.
I tried this:
Battle ArenaApr 10, 2014 10:04 PM Re: Verify Disk stops in Mavericks
Re: Verify Disk stops in Mavericksin response to BobFromIN
Hello.
I'm using Mavricks 10.9.2
Try this:
Open "Disk Utility"
Click the "Log" button (top right hand of window)
Click back to "DIsk Utility"
Select start up partition eg. "Macintosh HD"
Click "Verify"
I got the green text confirmation,
Also, the log should mention confirmation as well.
Looks like this is a simple bug.
and it seemed to work. But I agree with this:
Still not fixed in 10.9.4. Kind of annoying.
Hey, seeing the Green OK is an Extra Piece of Mind. Not seeing Red Errors is nice, but seeing Green OK is even nicer:)!
Let's hope that 10.9.5 or whatever other OS Update will fix this, assuming that Apple already know about this!
Here is a Suggestion I have for Apple:
If there is an Error with Macintosh HD Internal Startup Disk, it'd be great if there was a Button in Disk Utility that we could click on and it would do the Following:
Restart Mac into Recovery Partition
Open Disk Utility
Select that Macintosh HD Internal Startup Disk
Offer to Repair it
Why do I think of that Button? Because sometimes, particularly when it's not a very experienced user, who becomes nervous when they see Error(s) in Red, they might forget about
Just hold down Command-R during startup and OS X
as described here https://www.apple.com/osx/recovery/ and, if there is no Internet Access at that time, it might be harder for them to look this topic up.
But then, maybe such Suggestion is too hard to do? Just a thought on my part!
Either way, let's hope that this issue "Verify Disk stops in Mavericks" is fixed soon! Thanks in advance for your help, Apple! -

Sharing to DVD all my projects stops att 66 % - without error messages.
Sharing to DVD all my projects stops att 66 % - without error messages.
I'm a beginner in Final Cut Pro X. Not good at ¨computer terms¨ and computers so please take it easy when explaining.
My first three project was succesfully . (I then had no background image.)The fourth project (about 59 minutes) was at first successfully even with a background image. (But when I played the DVD on my DVD-player it stopped completely after 45 minutes, but went on when I tried to play it again, from the place where it stopped.) Then I replaced the background image with another and after that it stopped at 66 %. I read about the error -29 and made my image ¨smaller¨ but nothing happened. I also made the project shorter, about 57 minutes, nothing happened.
I tried a couple of completely new project from 2 – 20 minutes long – the same happened, it stopped at 66 %. (Read about deleting render files and tried that too without results.) I have a Mac OS X 10.8.3 Mountain Lion
Grateful for help after a week with problems. It’s a dancing project and people are waiting for the DVD…"What finally got it to work for me was Share>DVD>Settings>Backround; added a small jpeg, then removed. For whatever reason, it seemed to jar Create Disk awake."
Using this idea I didn't even add or delete an image, just opened the the Background window and closed it again.
This made one stubborn Project work/burn even with some retimed clips in it.
This action must flick an internal ON switch somewhere????
It's something simple but annoying. I have no idea where to look.
At least with a couple of extra clicks it's now working as expected.
Annamatilda might try the same to confirm the above??

After getting the dreaded gray/blue screen, I tried to run disk repair on the internal disk. I got an error message saying "Disk Utility can't repair this disk and restore your backed-up files. The volume Macintosh HD could not be verified completely." What do I do now? This is an iMac and I'm running 10.6.8.
Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it. See below for how to clone a drive.
1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
with your computer. Insert the disc into the optical drive and restart the computer.
After the chime press and hold down the "C" key. Release the key when you see
a small spinning gear appear below the dark gray Apple logo.
2. After the installer loads select your language and click on the Continue
button. When the menu bar appears select Disk Utility from the Utilities menu.
After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
size.) Click on the Partition tab in the DU main window. Set the number of
partitions to one (1) from the Partitions drop down menu, click on Options button
and select GUID, click on OK, then set the format type to MacOS Extended
(Journaled, if supported), then click on the Apply button.
3. When the formatting has completed quit DU and return to the installer. Proceed
with the OS X installation and follow the directions included with the installer.
4. When the installation has completed your computer will Restart into the Setup
Assistant. Be sure you configure your initial admin account with the exact same
username and password that you used on your old drive. After you finish Setup
Assistant will complete the installation after which you will be running a fresh
install of OS X. You can now begin the update process by opening Software
Update and installing all recommended updates to bring your installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
You may be able to backup your data if you have an erased external drive you can use. Before you do the above but after you have opened Disk Utility you can try to clone your drive:
Clone using Restore Option of Disk Utility
1. Open Disk Utility.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Select the destination volume from the left side list and drag
it to the Destination entry field.
5. Select the source volume from the left side list and drag it to
the Source entry field.
6. Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
Now this will only work if the drive is accessible and can be cloned by Disk Utility. Otherwise, you would need to access your drive from another Mac that you can connect via Firewire - Target Disk Mode. -
The attempt to burn a disk failed. An unknown error occurred (4000).
Whenever I try to burn a CD from iTunes, the burning process starts and continues for about two minutes, cancels automatically and then displays the following statement: "The attempt to burn a disk failed. An unknown error occurred (4000)."
Several Apple technicians have tried but been unable to assist me. They have pointed me to articles at http://docs.info.apple.com/article.html?artnum=93360 and http://docs.info.apple.com/article.html?artnum=93286 but none of the suggested solutions solve the problem.
1. I have the most recent version of iTunes (6.0.1).
2. All of the songs that I am trying to burn are authorized. For example, they include the Complete U2 Collection, which I recently downloaded from the iTunes Music Store.
3. I am not trying to burn a CD with the same Playlist more than seven times.
4. My CD burner works perfectly fine using other CD burning software, such as Windows Media Player or Roxio Easy Media Creator. However, these programs are not compatible with any of the many pieces of music that I have purchased and downloaded from the iTunes Music Store.
My hardware configuration is as follows:
Microsoft Windows XP Professional Service Pack 2 (Build 2600)
HP Pavilion 061 PJ467AA-ABA M1180N
iTunes 6.0.1.3
CD Driver 2.0.4.3
CD Driver DLL 2.0.3.2
LowerFilters: PxHelp20 (2.0.0.0), drvmcdb (1.0.0.1), Iviaspi (1.0.0.0), Pfc (2.5.0.204), Cdr4_xp (7.5.0.47),
UpperFilters: GEARAspiWDM (2.0.4.3), Cdralw2k (7.5.0.47), pwd_2k (7.5.0.47),
Video Driver: RADEON X300 Series\RADEON X300 Series
Found aspi32 running.
Does anyone have any suggestions as to how I can restore my ability to burn CDs from iTunes? Thank you very much!I am having the same problem. I get an error 4450 - unknown. I have purchased several songs but it appears I will not be able to burn them to CD.

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.
MatthewSOLUTION!!!!
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!

Powerbook G4 550Mhz Mac OS X (10.4.6) -
Hi,
Fed up with seeing the spinning beach ball I decided to reformat my MacBook Pro...
After backing up everything on an external hard drive I put in the OSX install DVD, restarted the machine and held down 'C'.
I followed the install prcedure, clicking next a few times etc...
I then went into Utilities > Disk Utility. I chose 7-Pass to erase the Macintosh HD and set it off erasing.
I checked the process an hour in and message on screen read:
Secure disk erase failed with the error:
could not open disk
The internal hard drive no longer exists in the disk utility so I cant retry erasing it.
The only thing that appears in disk utility is the OSX install DVD.
I can't even shut down the mac as everything under the apple tab is greyed out!
I'm guessing this means my hard drive is broken right?
If anyone has any other ideas of what to try I'd really appreciate that.
How do I turn the machine off?
If my hard drive is gone then should I consider getting an SSD drive?
Any recommendations for such a drive would be great.
Hope you can help!Did you partition the drive?
Extended Hard Drive Preparation
1. Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger or Leopard.)
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.
