Harddisk suddenly missing in Disk Utility

Hi,
My 2nd hard drive is missing in Disk Utility. It doesn't show in Finder either.
System profile is the only place where I can see the physical drive, but no partitions are displayed. It only shows this:
WDC WD5000KS-00MNB0:

Revisie: 07.02E07
Serienummer: WD-WCAN**262

Whereas for my ROOT drive it says this (including the partition)
WDC WD2500JS-41SGB0:
Capaciteit: 232,89 GB
Model: WDC WD2500JS-41SGB0
Revisie: 20.06C04

Furthermore I cannot shutdown my system with this particular internal drive connected. It hangs after a few seconds. With a hard reset using the power button, I removed the whole 2nd drive bay and after a restart leopard shuts down as normal. Since I cannot see the drive in Disk Utility, how am I able to repair it? Any help would be really appreciated. Thanks.

Try Disk Warrior (you'll want to have a system for just maintenance and repairs only); or Drive Genius 2; or TechTool Pro.
The directory and journaling could be so corrupt for various reasons it can't be mounted. Bad sector.
Other than anything not backed up I'd RMA or zero, but I'd also invest in replacing with a new model.

Xserve RAID volume corruption, volumes missing in Disk Utility

I have an Xserve with 3 drives in a RAID 5 set. The RAID set is divided into 2 volumes. After hard booting the server to recover from a crash, the volumes seemed to disappear.
We booted to an install disk and ran Disk Utility, which showed that there were no volumes at all. We then ran RAID Utility, which showed the volumes there.
After the RAID ran a re-initialization and verify, RAID Utility shows green lights throughout, as if everything is fine. Nothing else, however, can see the volumes.
We booted to an external drive with OS X installed, and basically found the same situation. Only RAID Utility can see those volumes, but otherwise they're just plain missing. However, RAID Utility does show "Partitions: None" for both of those volumes.
We have tried placing the drives into another server to determine if the problem is with the RAID card, but we had the same results. I also tried booting to target disk mode, but the other machine can't see the volumes all the same.
Using an external boot disk, we upgraded the RAID firmware. We also reset the SMC, as well as the PRAM. Nothing is working so far.
AppleCare basically told me that we're SOL and have to rebuild. Unfortunately, there is some data there which was overlooked in our backup procedure. If there is any possibility of recovering the data, I'd like to try it before giving up.
My absolute last option is to recreate the volumes exactly as they were before, then hope that I can use some manner of un-erase to recover the data. However, I'm not sure how RAID works on that level, should it just jumble the data, or if this is even remotely a feasible option.

Port 1: Link Established
2Gps
Point to point
Status light green
In the system Profiler I'm not sure what you're asking for, I'm running 10.5.8 standard not server.
the fibre channel shows link established 2Gps and cable type copper but nothing else, the disks & RAID controller don't show up anywhere I've looked.
RAID Admin shows the JBOD disks as online and lists the LUNs etc.
System looks fine, only error is missing second power supply.

Partition tab missing in Disk Utility

I have a 2011 iMac that came with Mtn Lion. I have a WD 2 TB external HD that I reformatted, as it came with WinOS. I formatted it with Disk Utility to MAC OS EXTENDED (JOURNALED). I have Carbon Copy Cloner (v.3.5.3) and want to partition the external drive to be bootable. However, DU has no Partition Tab. How do I then partition this to be bootable?
I am using a separate HD for Time Machine.
Please advise. Thanks!

Welcome to Apple Support Communities
You need to select the highest level of the external drive listed in the left column of Disk Utility.
Once one partition is created on the drive and you select it, that partition cannot be further partitioned, so the Partition tab does not appear.

Fat32 missing in Disk Utility?!

Hello, I want/need to format my 2GB USB stick to Fat32 to use with my Xbox 360.
I have done this successfully on my Mum's old Macbook running 10.5 so assumed the process would be the same.
I opened up Disk Utility and erased it, then in the partition tab clicked on options then "Master Boot Record" as that should give the option for Fat32, yet only Fat is available. After formatting it as Fat and hoping it would work, I got an error saying it needs to be in Fat32 to be read.
So am I doing something wrong, or is there a third party disk utility-like app that will format it to Fat32?
Thanks guys, baRRy

Thanks to Tom Craigen for this command line method of formatting FAT32. I found this archived thread, and Tom's instructions are the last post in the thread:
http://discussions.apple.com/message.jspa?messageID=8509160#8509160
I had to download a firmware update for my Vizio LED LCD HDTV. I hardly ever have a Windoze computer handy. I found a jump drive and used this archived thread to format the drive. Then I followed the firmware update instructions from the TV manufacturer's web site. I was able to do the update just fine using Disk Utility and Terminal command line. Thanks, Tom!
If you decide to try this FAT32 formatting using Terminal, and you are new to using Disk Utility and Terminal, and using Unix language and instructions, maybe you should get someone to help. At least read the instructions carefully, and be sure anything you do is only with the jump drive or disk drive you want to format. The commands will wipe the drive.
You can do in Terminal what Disk Utility does not (yet?) do. You still need Disk Utility to do some of the work, but Tom's command line instructions will do the formatting.
There are a couple of spots that might not be clear (in item 9, the word, "Apple" appears when he meant "Apply"), but the context should be fairly obvious. When he says to select the drive you want to format FAT32, he means this is within Disk Utility.
The instructions assume you are starting with a jump drive that the Mac recognizes, but might not have MS_DOS FAT32 formatting. Just to be sure, since I don't work in Terminal very much, I probably overdid it, formatted the drive with 1 partition, and chose the Mac OS Extended Journaled format to make a fresh start.
For one thing, if you don't start with the Mac OS format, you might not get the partition menu in Disk Utility, and that's very important. I was working with an old 126Mb jump drive, and I only needed 8Mb, so I made just one partition.
Before you make any changes to the format of the drive, while the format is still Mac OS Extended Journaled, check in the System Profiler, under the Hardware menu, the USB item. Locate the drive identifier. It will look like disk1s#. Mine, for example, was disk1s1. That's the jump drive -- not to put too fine a point on it. You really want the right disk ID, because the command line script totally erases the disk and formats it FAT32.
Once you follow the instructions, you can double-check in Disk Utility. I suggest you quit Disk Utility, then start it again. Click on the newly formatted drive in the left list of the available drives. The FAT32 format should appear in the descriptions below the window in bottom margin. If it shows up at FAT16, try the command line text again: newfs_msdos -F32 -v "yourdrivename" /dev/rdisk1s# [where # is your specific drive's number. Check Tom's items Tech Part > 4. and 5.
In my case, once I had the FAT32 jump drive ready, I had to download the firmware update file. Of course, the Mac could not do anything with it, but it did download. I went to the Downloads folder and dragged the file to the jump drive. I had to change the name of the file, following the manufacturer's instructions. I followed the manufacturer's instructions on everything, and once I had the drive inserted, and powered up the TV, the firmware update took off and did its thing. I'll watch for the hoped-for improvements in performance for a couple of days. I don't want to make the hike back to Cost**.
The beautiful thing about this TV is that it is natively 12 volts, and we plan to use it in our RV. Cool energy savings!
Please don't hold me (or Tom) responsible if something goes wrong. Go slowly and follow the instructions. If you've never used Disk Utility or Terminal, back away from this process and try something safer.
Holiday cheers,
Anne

Partition Tab Missing: Disk Utility

I've just noticed that the "Partition" tab is missing from Disk Utility.
Suggested correction?

Make sure you have a drive selected, at the left in the left column, not a volume, indented below the drive.

Disk Utility Cannot Repair

About one month ago my system at startup was acting odd, the menu items in the top right corner were missing and Disk Utility would not repair the volume, DiskWarrior was real slow in trying to repair the volume so I decided to Erase the Drive and install the OS fresh.
Well this morning at startup after the progress bar I was faced with a black screen with with writing. I started from the install Disk and tried Disk Utility, it could not repair the volume. Keys out of order and missing items were what I saw. I tried Disk Warrior, it was able to repair the volume, hardly any errors shown, no long report for those familiar with DW. However when I went to restart I ended up with the startup you see the 1st time you start your Mac, looking for registration etc after the Welcome video.
Once again the menu items in the upper right hand corner spotlight and clock are missing.
Any Ideas what can be causing this. DW is set to check the HD's SMART status and has never found a problem, the computer is used primarily for email and internet access. It is the G4 that is having these issues.
450 MHz PowerMac G4 40 GB HD 1.12GB SDRAM 700 MHz eMac 40 GB HD 768MB SDRAM iMac 266 MHz 96MB SDRAM Mac OS X (10.4.5)

I don't do hardware
Try looking in "do-it-youself" repair.
EDIT: To find drives that would be right you can look at OWC

Mounted .iso file shows in Disk Utility, but inaccesible through finder

Hello.
I have an .iso file that used to mount flawlessly, but now when double clicked shows only in Disk Utility, while remaining inaccesible otherwise (finder hierarchy starting from computer should show all mounted drives, but this one is missing). Disk Utility doesn't find any errors. Is there any other way to find out what's wrong?
thanks

Do know the name of any file that is on the iso image? If so, do a Spotlight search on the file name and see if it show up. If it does, Command click on the result in the Spotlight list and see if the enclosing folder opens in Finder.

PS--Forgot to aske: when you said "shows in Disk Utility" I'm assuming it is shown not just as existing, but as being mounted.

Disk utility doesn't show external Time Capsule harddisk

Hi.
With an older OS X, it was possible to use disk-utility for making some changes at my TimeCapsule(3rd.Gen.)-harddisk.
Now i tried this with the latest version of Yosemite. I think, at the 1st view to to disk utility window, there was an TC-ikon shown under the SuperDrive-ikon. But some seconds later it was gone! I tried it again after restart my iMac an the TC, but every time finder-window and disk-utility-window looks like this ..
... with added comments in green ("Finder"-window, "disk utility"-window) and red (lost "TC-Harddisk?"-ikon).
I tried this also with a MacBook-air (newest version) - same result
What happened? Is it a Yosemite-Problem?
Can I do something with the terminal-app to get the connection?
<<<---- I posted this Nov.2014 at Mac OS & System Software / OS X Yosemite
Today I connected an USB-Stick with my TimeCapsule. Then I opened Disk Utility and was happy - for some minutes.
At the window of the Disk Utility I saw the TC-Harddisc an the memory-stick too.
But when I tried to add an partition to the TC-Harddisc, it was gone away.
I closed-and-started the disk Utility again - now TC-Harddisc was shown.
I disconnected-and-connected the memory-stick again - now TC-Harddisc was shown at the disc-utility-window.
Thanks for Help!

You cannot partition a TC disk from disk utility in the Mac.. that has always been the case.
What you did last time is partition the sparsebundle.. that is a virtual disk created by the computer.. merely partitioning a virtual disk is pointless.
You simply need to create another sparsebundle or dmg file to use as virtual disk.
But the fact that Yosemite continually loses connection to the TC .. oh yeah that is because Yosemite is buggy.
Reset your TC to factory.
Do this manually..
Factory reset universal
Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.
Then redo the setup in the airport utility. Use short names with no spaces and pure alphanumeric characters.
Same with passwords only longer.
I recommend you then mount the TC in finder manually by its IP address if at all possible not by name.
The problem here is the IP must be static which it is by default if the TC is the main router but it will have to be specially setup if the TC is bridged.
Use Go, Connect to Server.
SMB://10.0.1.1
When asked for the disk password type that in and do not forget to save it in the keychain.
Then you can mount a TM sparsebundle in disk utility if you want.. although I suggest that is pointless other than to verify your backup.
Do not partition it.. that is not helpful at all.

My usb that i have been using on my computer for a while suddenly stopped working, but is still glowing and letting me know that it is connected, but not showing up in disk utility

my usb that i have been using on my computer for a while suddenly stopped working, but is still glowing and letting me know that it is connected, but not showing up in disk utility

Either the physical drive or the enclosure electronics has failed. The light you are seeing is powered by the USB connection, the power, electricity, all USB ports put out. That doesn't mean the actual physical hard drive or the USB to SATA bus electronics are working properly. If it doesn't show in Disk Utility then it is DEAD.
Most of the time it is the enclosures electronics that fail. Removing the physical drive from the enclosure and put it in another enclosure or using a SATA to USB adapter, one that has it's own AC power supply, might allow you to get the files off the drive.

My Western Digital external hard drive suddenly stopped showing up on my Macbook Pro and disappeared from Disk Utility. It works on a PC.

My Western Digital external hard drive suddenly stopped showing up on my macbook pro and it disappeared from disk utility. I have tried making invisible files visible but nothing has worked and my hard drive shows up on a PC but not my Mac anymore.

What is the manufacturer of the external and how old is it? Does it have its own AC power supply or is it USB bus powered?

I can't burn a dvd using any method, Idvd tells me that my super drive is missing, dvd studio pro quits when i click burn and disk utility keeps spitting the disk out when i click burn and enter the disk??? how do i repair my superdrive for imac

I can't burn a dvd using any method, idvd tells me that my super drive is missing, dvd studio pro quits when i click burn and disk utility keeps spitting the disk out when I click burn and enter the disk??? how do i repair my superdrive for imac, or how do I do whatever I need to do to get it working: I have already tried using a lens cleaning cd and also restored my nvram or something i forget what it was called but i restarted my computer holding down command+optoion+p+r and still nothing???
Free solutions are the best, although if I have to pay I will, I would prefer to not have to buy an external burner if possible and already know that is an option so please don't give me that answer... thank you for any help you can give

Unless your iMac is still covered by AppleCare, get an external DVD burner.
You can get perfectly good ones from Amazon for less than $40.

Disk Utility suddenly showing my HD in red

Hi all,
I was using Disk Utility over the past couple of days to look at a couple of external drives. Then, late yesterday DU suddenly started displaying my HD description (over in the left hand column) in red. Selecting it, the main window says DU says this disk has hardward problems that can't be repaired and to get it replaced. Down below the main window where it has the basic stats, it says in red "Failing"
I just thought I'd ask whether anyone has experienced this "alert" status before and if it can be trusted. I know that seems like an odd question to ask but it's simply that, like many, I've experienced mixed messages from software that isn't necessarily correct and can be caused by something else.
I had a lot of hardware replaced about 9 months ago, including the hard drive. That's another reason I'm scratching my head. I'm all backed up (Time Machine) so I feel confident about my data. I guess I don't relish the idea of having to haul my iMac 7,1 to the Apple Store. Of course, I will but . . .
. . . Any thoughts?
(My unit IS taking a longer time to boot up--30 seconds grey screen with twirling wheel, long blue screen . . . .)
Thanks so much.

Thank you, a.
Yes, the whole repair episode last year was nightmarish. I had to get Apple Support by phone involved. He looked at the repair docs online and commented that it was a very sloppily done job.
I've made an appt with Genius Bar for tomorrow.
Thanks for your confirmation. It's nice to be able to get the opinion of a community member.

Disk Utility Error Message - Missing EFI + MediaKit

Previously setup was with 2 partitions, one for normal use while the other had the Lion Install ESD on it, used when I installed some time ago. The other day my machine suddenly shutdown and when I started it, it stated that the Lion Install ESD partition was corrupted.
I created a new Lion Install ESD partition and made a clean install (I was going to do so anyway).
My machine is booting fine, but it acts funny in the Disk Utility. First, an overview of my disk:
However if I attempts to "Verify Disk" on my disk (not on a specific partition) via the Disk Utility the following error is shown:
Even more strange is when I attempt to let the "Macintosh HD" use maximum space on the disk. It is currently sized at 230GB, but if I use the Disk Utility to increase it to say 231GB it reports the following error:
However, the space is clearly unused. And if I simply drag the partition down to use all the space the error will not prompt but nothing will happen.
In the time between my first install of Lion and the recent shutdown I had installed rEFIt after attempting to run Ubuntu, however it was quickly uninstalled again with no issues in the following months.
So, any clue what is going on with my disk?
Thanks in advance!

Maybe some added info will help. I have no problems starting the machine and using it. It's just that when I went to fix permissions and accessed disk utility from the hard drive to do it, I got the error message noted in my first post. I am wondering why that is, since it didn't happen before. I did use my 10.4 OS disk to start up just so I could fix permissions (that did fix permissions), but trying to repair the disk (to hopefully fix the problems I was having when I tried to access disk utility from my HD) didn't work. That's when I got the second error message. Is that because I've upgraded my OS to 10.4.11? I did that w/the Apple on line upgrades, so I don't have a 10.4.11 disk. Is that the problem? Also, do you know if there is a 10.4.3 upgrade? Thanks.

Disk Utility and fsck report 'missing thread records' and can't repair.

Hello,
What first made me realise there was a problem with my iMac was that when I tried to update a application it failed. I then manually download the .dmg of the update and tried replaced the app (Transmission 1.82 being that app in question). This failed, OS X claiming that it could not replace the older version (1.81). I then tried copying the file to the desktop where OS X claimed that there was already a copy of the application and so left a corrupted file on my desktop. This also happened when i attempted to move and copy a couple of pages documents and movie files around. I decided the best thing to do at this point was to reboot my computer; OS X decided it needed to install a couple of security updates at this point. This installation failed.
My iMac booted up, but only after a progress bar has appeared under the Apple logo and spinner and has done its thing (From what I've read this means that OS X is trying its best to resolve some sort of errors). This happens upon every boot.
This made me think that something must be going on with the file system of my Mac so I ran all the tests in Disk Utility. Permissions repair ran fine and fixed a few issues, but when I verified the disk this is what it reported:
"Verifying volume “Macintosh HD”
Performing live verification.
Checking Journaled HFS Plus volume.
Checking extents overflow file.
Checking catalog file.

Keys out of order
The volume Macintosh HD was found corrupt and needs to be repaired.
Error: This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk."
I booted up from the DVD and tried to repair; this failed. Next I tried using fsck in single user mode; this also failed. Upon rebooting again and waiting for the progress bar to fill I was able to move files around and update Transmission without issue. Disk Utility still reports the same error.
If I boot into Windows Vista everything works perfectly; as of yet I haven't got around to installing the new Boot Camp update for Windows 7 support incase that changes anything. When running the diagnostic tool on the Windows Vista DVD it reports that everything is fine for Windows.
I really am at a loss for what to do next. All my data is backed up by Time Machine onto a Time Capsule as well as manually onto a FW external. I also made a clone of the Windows partition using the free app Winclone. Does anyone know anything I can do to fix this problem?
Thanks so much,
Sam.

I have been experiencing exactly the same problem here with my MacPro. Apple replaced the hard disk because it was reporting bad sectors. However even with the replacement hard disk I'm experiencing the "missing thread" issue again. I'm guessing its either a software issue that keeps recurring or a fundamental hardware issue. Is the disk controller part of the hard disk or the motherboard? I've never had hard disk problems like this before.
Here's my Disk Utility report from earlier today:
