SMART: DiskWarrior disagrees with Apple's Disk Utility and TechTool Pro

DiskWarrior 4 is giving me SMART status warnings for my internal drive, specifically that the temperature is too hot, and may indicate an impending failure. This typically happens when my drive is rather busy, like doing a long backup.
However, both Apple's Disk Utility and TechTool Pro 5 say the drive is fine; Disk Utility says the "S.M.A.R.T. status: verified" and TTP does it's check of the SMART status, with result "Passed."
Who do I believe?
Thanks.

That is hot, it sounds like you have a cooling problem!
Most drive manufactures only recommend an operating temperature of 140 F (60 C), here are the Spec's for the 320 GB WD Caviar Blue that I installed in my Early Core Duo just a few months ago as an example: http://www.wdc.com/en/products/products.asp?driveid=299
What does iStat Pro say your fan speed(s) are?
You need to check or have your fan unit checked out to be sure the fans clean and working properly?

My 3 year-old macbook pro is very slow. I have run disk utility and virus scan with no improvement. The "beach ball" will spin for minutes at a time when opening, closing or changing windows. Apple Store looked at it a few months ago with no help.

Cant restore my macbook with Disk utility and my .dmg image

My macbook would not boot anymore. Stuck on gray screen with apple logo, spinning wheel and a loading bar for a while after shutting off.
I was able to get to Disk Utility in the recovery mode and, after a while, was able to make an image of my filesin an attempt to back them up.
The .dmg was put on an external and i checked it on my imac, i could open the .dmg file and browse all my files from my macbook, so those are safe!
After that i tried to wipe the SSD of my macbook and put the image back but that didn't work, also some resource is busy errors.
After trying this a few times without succes i figured i'd try to do a clean install. This worked.
My macbook air is working again but if Iuse Disk Utility in the recovery now and try and restore my image (.dmg file) it gives me Restore Failure; An error (-16) occured (resource busy) as well. I also tried to copy the dmg onto my macbook and run disc utility when booted into OSX. I open up the back up .dmg with Disk utility, then i go to my macbooks partition (Macontiosh HD) and use that as a destination and drag the mounted image as the source as shown on the image below. Am I doing something wrong here?
Doing this i get an error as well: (-119,930,878) Resource busy as you can see.
What can i do to get my image back on my macbook? Any 3rd party software?
I considered just transferring the files after opening the .dmg file but this works only for documents and not for programs and settings of the default apps.
I've looked all over the Internet and it seems more people have had this error but then with making the image, they also suggest unmounting the destination disk before trying to restore but my destination is Macintosh HD, i cant really unmount that can i?
Thanks in advance!

To make a clone, in the future you need to use a program like superduper or carbon copy cloner.
Either program makes an identical clone while preserving certain system files and marking/indicating to OS X that the clone is bootable.
Using Disk Utility to make a DMG was a good idea, but this will not yield a bootable image.
If Disk Utility could do a 1:1 copy of everything, then people would be using it to rip/duplicate DVDs.
But Disk Utility does not (it leaves out certain invisible/system files), hence it cannot duplicate/clone a hard drive or DVD.

Yesterday I ran Disk Utility and came up with hundreds of permissions that needed repair. I hit the "repair permissions" button and waited until it said they were repaired, but just for fun I hit the "verify permissions" button again, and they all came back! I did this several more times and every time I would hit "verify permissions" I would get the same list. What's up? I've always suspected diagnostic programs, but this is Apple's own!

Ignore them. They aren't errors. You will keep seeing the same ones. As long as you get the message "Permissions repair complete," you're OK.

Disk Utility and DiskWarrior can't fix my hard drive. How?

For some strange reason, my startup external Firewire hard drive decided not to work.
Used my Mac internal startup disk and ran Disk Utility and I got this only error message:
*Error: The underlying task reported failure on exit*
Couldn't even mount it. So, I ran DiskWarrior 4.1 and the external FW HD showed up as an *Unknown Disk* and it stated +Directory cannot be rebuilt due to disk hardware failure (-36, 2268).+
Ran TechTool Pro 4.6.1 and the FW HD passed the Read Write test but failed on the Surface Scan with lots of bad blocks.
So, is this a gone case? Any other method or utility to revive the FW HD?

Hard drive failures are not that uncommon because hard drives still have moving parts. Since TechTool's surface scan came back with a lot of bad blocks and DiskWarrior noted that there was a hardware failure, my guess would be that the disc itself may be damaged or scratched.
There are companies that can recover data from damaged discs, but I would not put too much effort into reusing this particular drive.

I have an external hard drive from my time capsule that stopped working on me. I am attempting to access the data with a hard drive reader on my MAC. I am able to see the drive in disk utility and under system info USB. But I am unable to access the data.

I have an external hard drive from my time capsule that stopped working on me. I am attempting to access the data with a hard drive reader on my MAC. I am able to see the drive in disk utility and under system info USB. But I am unable to access the data and it does not show on the desktop when connected.

Ok if disk utility was able to verify the drive I doubt there is any problem.. are you trying to open a TM backup??
You need to mount the sparsebundle then check the actual info inside the bundle.
Don't use disk warrior.. if the disk has verified then unless you deliberately deleted files there is nothing that is going to do.
Pondini has a lot of stuff about getting access to the sparsebundle.
http://pondini.org/TM/17.html
But if you have copied info to the TC that is now gone.. and the disk is ok.. I am not sure.. the TC will not have deleted the files itself.

I did disk utility, and verify disk and it asks to repair the disk using dvd installer...but when i insert the dvd- restart- hold c, it keep ejecting and can't read the dvd....i tried with my friends dvd too, but still fail...mac osx v10.6.7

someone pls help me

Well there is Resolve startup issues and perform disk maintenance with Disk Utility and fsck witch includes step by step instructions to run disk repair without the install disk.
But before doing that, it's a good idea to backup. You may want to troubleshooting your superdrive / disk before hand. if I disk repair fails you may need the disk working to re-install the OS.
Dose the computer read any DVDs? if no, you may want to use Troubleshooting the slot load optical disc drive.

Is the Macbook Pro with retina display compatible with the share disk utility?

Hi,
I was wondering whether, since the macbook pro with retina display has no cd rom drive, whether the MBP is compatible with the share disk utility like the mackbook air
VKB

there should be no reason why it wouldn't be, as that's a feature of the OS, not the hardware.

Please help me. I just cleaned the disk and, when I clicked to install new OS X mavericks a screen with apple id popped up and said that I need to put apple id that purchased the OS X.

Problem with Disk Utility and with ITunes and with Classic

Greetings. I have had problems with ITunes recently; when I try to open it, it gives me the error message: "The ITunes Music Library file is locked, on a locked disk, or you do not have write permission for this file."
When I looked at the ITunes discussion section, people had two ideas for other people who had the same problem:
(1) Make sure that the library of music files is write-enabled (which it is) and not locked (it isn't) and
(2) Go to Disk Utility and repair the disk.
Since (1) is not a problem, I am trying (2). However, when I open Disk Utility, it just stays on the window, stating "Gathering disk information..." and proceeds no further.
Perhaps related to these problems, when I try to start up Classic, the window opens, but it gets stuck at the very beginning (stating "Classic starting up using System Folder ...") and proceeds no further.
Can anyone help me with these multiple problems? Thanks in advance.

amandel
The problems you report are different than those relating to the iTunes receipts/DU conflict. Trashing those receipts as suggested is necessary to get DU to repair permissions, but, as I understand it, you couldn't get DU to recognise your drives. And I've seen no posts relating to iTunes 6 and Classic.
I've had the problem you describe before (at least vis-a-vis DU). In principle DU's "Repair Disk" function would fix it, but of course if the disk's don't mount in DU then you can't fix them:)
Therefore fsck is a good solution, or trying DU from the Installer Disk (don't start to install, just let the first installer window appear, go to the menu and choose "Open Disk Utility") and repairing. Then reboot and repair permissions, preferably with DU running from your hard drive.
Maybe you're more of a "don't touch what's still running" kind of person, but it sounds to me like the systems a bit wobbly and needs some tender loving care. You could try a clean up using a program like OnyX as well - it won't do any harm.

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.

Time Machine, Disk Utility, and clearing out corrupted snapshots

Hi, all. I've been having some troubling issues with Time Machine and could use your collective insight.
I have a 500GiB external USB2 disk that I've been using for Time Machine since December (the oldest snapshot in Backups.backupdb is named 2007-12-13-222250). Everything worked fine until sometime in late January, when Time Machine decided to ax 2/3 of my Applications directory. Time Machine's logging is terse, so I wasn't able to determine what caused the corruption. The fact that this error wasn't caught and flagged by Time Machine bothers me.
Especially because I discovered this in the process of needing to recover from a crash on my laptop's hard drive -- I had to roll back to a previous, complete snapshot to get all my applications back.
After that I had to engage in some jiggery-pokery to get Time Machine to re-snapshot everything, but things proceeded normally until I received my new copy of DiskWarrior 4.1 last night (although DiskWarrior is an innocent bystander here). I tried to use DiskWarrior to rebuild the directory on the Time Machine disk, but it failed before trying to write anything.
(For those who care: after some back and forth with Alsoft tech support, we determined this was likely because my Time Machine volume has 6.2GB of catalog data, and DiskWarrior works by rebuilding the directory in memory, so it has to be able to fit the whole catalog into virtual memory.)
I was a little paranoid that something might be wrong with the disk after that, so I fired up Disk Utility and told it to repair the disk. It churned for about 6 hours and repaired an extraordinarily large number of hardlink reference count errors, but completed by claiming that the disk had been repaired.
When I next told Time Machine to run, instead of copying over a couple GB of data like it usually does, it started copying 38GB! ***? I took a look at the previous Time Machine snapshots, and discovered that Disk Utility had totally corrupted every snapshot I'd made since last month's fandango. Most of the root-level directories in the snapshots now look like this:

That is clearly, completely wrong, and it alarms me that Disk Utility could cause so much damage to a Time Machine volume.
Since I also use SuperDuper! to regularly clone this disk, it's not as big a nightmare as it could be, but this means that I'm going to have to clear out every snapshot for the last month by hand, both because I obviously can't trust them anymore, and because I keep getting messages like this in the logs:

I'd like to keep the old snapshots if I can. What's likely to happen if I just go and clear out the b0rked backup sessions by hand?
(Hmm... it appears yes, because I just deleted them all and the disk didn't recover the freed space.)
Here's the important question: has anyone else had issues using Disk Utility on a Time Machine volume, and does anyone at Apple have any plans to add integrity checking to Time Machine? As it stands, I don't really feel like I can trust it in its present form, as convenient as it is...

I have trouble with disk utility on my new (1 TB Lacie) as well as on my old (500 GB WD) drive. After doing a backup, du tells me a never ending list of errors like
HasFolderCount flag needs to be set (id = 599567)
(it should be 0x10 instead of 0)
Everything was O.K. before doing the backup; so is the disk to be backupped, according to du.
Up to now, no other problem occurred, but I´d like to clear this issue before my trust in time machine is restored.

Difference between running Disk Utility and "Archive and Install"

Hi all,
I'm one of the poor souls who is having trouble with the software update 10.4.6. My iMac stopped halfway while doing the update, and when it attempted to do a restart, the iMac froze. I did the mistake of forcing it to shutdown, instead of just letting it take its time.
Last night, I attempted the Safe Boot but it did not work. The progress indicator kept on spinning for hours! SHOULD I TRY IT AGAIN?
Also, can someone tell me the difference between unning Disk Utility and "Archive and Install"? I figure I might have to do one of them to repair my iMac. I just want to do something that will reduce the chances of me wiping out my files. I also have the TechTool Deluxe CD with me. Should I be using that instead?
Please help.

i just had a simialr issue with my powerbook. I stress similar, but in the end i had the same issue with the start up screen (light blue, apple icon and the spinning indicator below it. I could not get past it.
I ran disk utility from the boot disk, and got a kernel panic on verifying and and repairing permissions.
So (and this is what Im suggesting you try) in disk utility I made a disk image of my internal hard drive and saved it to an external hard drive. Takes a while but a worthy precaustion.
Second I went ahead and installed the OS on the external drive. Once that was done I boted from the external to oprn the disk image back up of my powerbooks internal drive. After that checked out i wnet back to the boot disk and did a clean install of the OS (wiping the internal) and things were fine after that.
maybe wait and see how other people respond to this before jumping into it, but its smart to back everything up on an external any day.
much luck to you
-justin!
