MacBook Pro :: Internal HD Not Recognized Even In Disk Utility
Nov 3, 2010
I have a 2009 13 inch macbook pro with 2.4 ghz processor, 4 gb ram, all stock from apple. Machine has been working great until 2 days ago when my system froze, had to push the power off button, tried to reboot but got the flashing folder and the internal hard drive was no longer recognized. I did all the usual things and read the apple support page to no avail. I booted from the install CD and the drive is not recognized in disk utility. I took the drive out, put it in an external case and booted from there and the drive appears to be working.
I put in another internal drive, a Hitachi 500 GB/7200 RPM that looks mac compatible, disc utility will not even recognize it either with the external hard drive OS running or from the install CD. In system profiler, under hardware, it says this computer doesn't contain any ATA drives. Could this be a problem with the SATA cable internally? The rest of the logic board appears to be working as I am typing this on the affected machine running the OS from my former internal hard drive that is now in a casing.

However, my hard drive appears to be running fine - haven't noticed any degradation of performance since receiving the warnings two days ago. And HD is still running quiet (no strange mechanical noises I'm accustomed to hearing prior to a failure). Nevertheless, I'm installing a new HD tomorrow and recloning it from a backup external drive (operating from external until then).

The internal card reader on my MacBook Pro 13" (5/2011) worked just fine until a few weeks ago.Today however it left me in the cold.The SD card that I normally use does not show up anywhere, not even in Disk Utility. Other SD cards don't show up neither. There was no pbm accessing the data using an old Windows PC.A user friendly Sofware Function Test of the Internal Card Reader could give a quick answer where to look for error.

I recently formatted one of my HardDisk using the Leopard's Disk Utility into FAT32 format.
The HDD works well with the MAC however it will not mount on a windows XP machine.
The hardware detector detects the USB external harddisk but is not able to mount it. When i use the Windows Disk Management Utility, the hard disk appears with a (Not Initialized) and Unallocated warning message.

I have purchased a Seagate 500gb 2.5 inch laptop hard drive to replace my feeble 120gb drive. I am trying to set up this drive using carbon copy cloner before changing it over, I'm using an external enclosure for this. The problem I'm having is the hard drive isn't recognized at all.
It's not showing up in finder or disk utility so I don't know how to format the drive.
I'm using Leopard 10.5.6
The instructions that cam with the enclosure mention setting the hard drive to function in master mode, what does this mean? I don't want to go to all the effort of changing the hard drive if there's some sort of problem, and I would rather clone my drive before removing it too.

"Disk Utility has lost its connection with Disk Management Tool and cannot continue. Please quit and relaunch Disk Utility".
I keep getting this error when trying to erase an external hard drive with Disk Utility. When I restart, the error appears again. I've seen others with this problem but haven't found a solution. I've tried removing iTunes from Applications and deleting select iTunes receipts.
I'm running OS 10.4.11

I have had a problem for about a month whereby my MBP won't shut down, it just hangs after it has cleared the desktop and only the wallpaper is displayed. Now disk utility won't see the disk at all, and Software Update also does not find any updates. It checks for new software for ever. My mac starts up fine, and I can use it as normal.

I just replaced the internal hard drive on my G4 iBook. My problem is the drive is not showing up in Disk Utility, the system install disk, or when I have the iBook in target mode and connected to my tower. I believe the old drive had died. When I ran the Hardware Test on it, I received an error code on Mass Storage. After installing the new drive and running the Hardware Test, the Mass Storage passed. I take that as a good sign.?
Before cracking the iBook back open, I was wanting to find out what all the problem may be and what things to check while I have it open since that is not that quick of an operation. I'm already assuming to check the connections on the drive. But if they weren't secure, would it still pass the Hardware Test?

I just installed a Hitachi 1TB drive in my dual 2.5ghz powerPC G5.
I carbon copied my old harddrive over to it.
I didn't want to reinstall my OS.
However I think I copied some problems over.
In Disk Utility when I try to Verify Disk Permissions, Verify Disk, or Repair Disk Permissions (any of the options I am allowed to do to the startup drive) it moves like 1/5th of the time bar meaning it is working then changes to "It will be completed in 1 minute" then stalls there.
Information:
Dual 2.5GHZ PowerPC Power Mac
Mac OS X (10.4.8)
30inch Apple Cinema Display, 4.5gb Memory, and 1.5TB of Harddrive.

I tam trying to add a 75 GB partition to my aluminum iMac's internal HD using Leopard's Disk Utility, but after 7 hours the striped bar appears not to have made any progress and still says "Modifying Partition Map". How long does this usually take? Is this normal?

here's what's wrong:
1- Under sound in system preferences- output volume is muted and I can't un-click it
2-Also under sound in system preferences no devices are found under output and input
3-The sound symbol doesn't show in the top toolbar.
Also I googled this same problem and a lot of other people say a red laser is coming out of the head jack on the computer, I however don't have this problem.

I get this question mark along with a folder when starting up. I tried holding down the option key when turning on the power and then I get an internet recovery along with a globe. I click on the arrow below it and it takes maybe 15 minutes to start up. Then i get this disk utilities screen. I'm now unable to do anything. When going into disk utility, disk 0 shows with Mac OS X base system underneath it. All the clickable buttons are faded out. Is there something wrong with the hardrive? and where could i get this fixed? There isn't a warranty on it.

Macbook Pro running on OSX Mavericks is having problems.
Today I turned my Mac on, and it started up with a loading wheel and a loading bar. When the loading bar finished, the Mac turned itself off. I tried many times, same happened every time. I then went into OSX Recovery, started repairing Macintosh HD, but the error message saying "Disk Utility can't repair Macintosh HD" came up and now I don't now what to do.
Is there any way I can back up my files in this situation? Is there any way I can repair the disk without having to erase all data and reinstalling OSX? Or do I really need to bring it to a Apple Store for repair?

MacBook Pro, OS X Mavericks (10.9.4)

I have a Seagate 1 TB Backup Plus Drive which was working perfectly fine until I plugged it into a USB hub. It detected it while in the hub and I was able to get files off of it, but when I ejected it from the hub and put it back into the USB slot on the computer it was not detected by finder. It shows up in the disk utility and I clicked verify and repair and it says:
Verify and Repair volume “Seagate Backup Plus Drive”
Checking file system
Volume repair complete.
Updating boot support partitions for the volume as required.
Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
Is there any way to get this to work properly again? Or if not is there a way for me to recover my files on the external hard drive?
I have a Macbook PRO late 2011 running OS X Mavericks.

Fortunately I got a time machine backup. And its restoring the drive while in Lion recovery mode. Here's what happened... I dont have a router a my place at the moment and so my two phones (iphone 4 and htc android) connect to my internet using my MBP's wifi via internet sharig. For some reason they were not able to get an IP from the mbp. After doing some wifi swtich toggles and forgettig & rejoining the network, i decided to reboot all my devices. I shut down my modem, phones and restarted my mbp. On reboot, after the chime, it showed an unsusal 'progress bar' under the apple logo. The bar progressed to about 10% and then the mbp just powered off. This happened several times even after PRAM and SMC reset.
So now i booted with cmd+r pressed and in recovery mode ran a 'verify disk'. It said the verification stopped and that i should repair the disk. When i tried to do that it said the disk cannot be repaird and that i should back up as many files as possible and attempt to format the disk and restore it with time machine. It is precisely what im doing at the moment.
1. Mbp wont sleep even when internet sharing is off
2. Mbp wont lit the onboard display upon opening it in clamshell mode until i removed the 3.5mm audio cable of my speakers from the audio out port!

I just upgraded my MacBooks hard drive and put in the install cd to restore from my time machine backup. Evedything went smoothly until I chose the new hard drive as the destination for the restore. I was told that the install failed to erase the hard drive and to restart and try again. So I did but when I try to erase or partition the drive, there is an error and it fails. The hard drve seems fine since it can be seen by disc utility but after it fails to partition or erase, it disappears from the disc utility forcing me to restart. The process I've done about 5 times now is boot the comp, choose time machine restore, then while the install is calculating the space the restore would require and searching for discs to install on, nothing shows up so I go to disc utility and try to erase or partition the drive only for it to fail and disappear from disc utility. At this point I hold down the power button to turn it off and restart the process.
The first time I tried, the restore process saw the drive while calculating the restores size requirements and allowed me to go the next step where it would automatically try to erase the hard drive (without me having to go into disc utility myself) but after the first try, it just says "searching for disks" and so I go into disc utility myself where I can see the disk.

I recently went through the very arduous process of replacing the harddrive in my aluminum G4 12" PowerBook. The process was a complete pain in the rear, and I ended up ripping a socket off the motherboard.

I just saw that the amount of memory left on my HD just dropped around 60GB, so I used the "Verify Disk" option on Disk Utility, and the output was: Verifying volume “Macintosh HD”Performing live verification.Checking Journaled HFS Plus volume.Checking extents overflow file.Checking catalog file.Checking multi-linked files.Checking catalog hierarchy.Checking extended attributes file.Checking volume bitmap.Checking volume information.Volume header needs minor repairThe 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 don't have the disk right now, so is there some other way I can repair it, get another install disk, or anything else? I've been thinking of booting up with a Linux livecd, but can it access the HFS+ filesystem?

My Macbook crashed so I tried everything to restart it. what finally worked is opening it from the install disk. I performed a "repair disk", and after saying "invalid node structure" and "invalid record count", it says it cannot repair the disk. I don't know what step to take next. How do I see if time machine has backed my files up? Do I need to erase the HD and reinstall?

After I erase the hard disk it shows 74.5gb free, almost. It says there is 42.3mb of space being used by 2 files which I understand are used for read write or partitioning or whatever.
When I then leave disk utility and go to the actual installer, the destination disk (untitled - 74.5gb) shows only 73.9gb free space. What is taking up an additional 500mb of space on the hard drive?
Apple support told me that somehow the disk has been altered and I lost space on the disk or I am now using a seperate partition that isn't showing up. Disk utility shows only one partition with 74.5gb free space. He told me I can find information about how to 'merge' the disk on the apple support section under troubleshooting articles for disk utility. I have been unable to locate this information.

I have a 2TB Western Digital My Book Studio FW800 external that has 5 partitions, connected to my 2011 iMac. I had help doing the partitions and don't really remember the reasoning, but one is just for my SuperDuper! backup, one is Miscellaneous, one for movie clips off my camcorder, one for misc scanned photo's and one for my genealogy research. I back up using Time Machine to a Time Capsule and also to this WD hard drive with SuperDuper!
Recently I'm getting a pop up message that "Mac OS X can't repair the disk "Genealogy"'. And it needs to be reformatted. It's become a read only disk. When I look in Disk Utility it shows all the partitions as "Mac OS Extended (Journaled)" EXCEPT for the one in question. I also noticed that there are a lot of files with "date created" being the same date in 1969! These files may be letters I've written or photo's I added to that partition within the last few years.
I think I have to completely reformat the entire external hard drive to repair this, but I want to make sure. Because it's going to be a major hassle backing it all up to another external (having to get one first) and then figuring out how to make the files that have turned "read only" in that one partition, back to their original state! Does this sound right, that I have to reformat the entire external hard drive? And how do I get the read-only files back to their original state.

I had windows vista installed but suddenly the audio decided to become faulty, after spending a day trying to fix it i realized I have a windows 7 install disc so i might as well just replace vista with windows 7. I didnt take care of vista or ever register it so it became quite a task to upgrade so i just deleted the partition and went to create a new one and just do a full install of windows 7.
I made the partition but the wrong format, so i removed it through boot camp assistant and created another, except now it keeps giving me the "back up the disk and use disk utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using boot camp assistant again" Now, I'd love to do this, except I have no idea what I'm doing and WHY this error has occured. After becoming frustrated I switched from my imac to my macbook pro and received the same error when trying to create a partition. So any help on exactly what I need to do would be a HUGE help. I only use windows for music production (I know, seems backwards, but I use Sony Acid and FL Studio so I'm stuck with Windows)

I'm trying to repair my hard drive. I restarted from the OS X Mac Mini install CD (holding down the letter C when I heard the chime), opened Disk Utility from the Utilities folder, selected my hard drive image, but the "verify disk" and "repair disk" options are grayed out. I'm at a loss as to how to proceed.
