Internal drive not mounted

My Macbook Pro will not mount my internal drive. I tried using Disc Utility from my Snow Leopard disc but it states that the drive is not mounted and that i need to restore and recover.I have seen a few threads about Lion and issues with mount points but they mostly addressed external and secondary drives.Any suggestions?

That's what it seems like from your tests.
A tip for the future. Get an external drive and keep a bootable clone of your internal drive. Keep it updated with a program like SuperDuper. In the event of a drive failure, you can alway boot from the external clone. Makes it easy to restore to a new drive.
Good Luck

2nd internal drive not mounting, melodic tones at startup

Main drive with System folder on it opens fine at startup, 2nd drive which is a 160 GB Maxtor drive will not mount, nor show up on Disk Utility. Both drives are connected correctly to a Sonnet Tempo ATA/133 card and have been working fine for over three years. Yesterday I went to startup and my computer made a melodic tone similar to a cell phone ringing. Is this an indicator that something's wrong with the drive? The computer is a 867mhz Quicksilver running OS 10.2.8. I tried a few things, I ended up disconnecting the 2nd drive from the ribbon connector & power supply and the melodic tones quit playing at startup. I tried the same ribbon connection and power supply from the dead drive on my good drive and it works fine. I can always replace a bad drive if that is the case, but I had some important video projects on the drive without a backup (lesson well learned here, ouch!). Is it possible to retrieve the data even though the drive will not mount? Any app suggestions or how do I attempt to accomplish this? Thank you!

Many hours worth of work recovered from failed drive! Cool! If anyone out there experiences what I just went through here is what I did:
The Maxtor drive wouldn't spin at startup, apparently the drive has a melodic tone that is supposed to "kickstart" the drive into spinning again when it fails. Well, it didn't do it's thing for me, so I went out and bought a Western Digital drive (supposedly a more reliable brand) with the same 160 GB capacity. I installed and partitioned it, then I installed the bad Maxtor drive in the third bay and ran another cable to my Tempo ATA card's second patch. I left the computer side door open, started up the computer and the drive started to make it's melodic tones again. I knocked on the top of the bad drive with a rubber hammer - wwrrrr, the drive took off running again! It didn't mount the first time, but after a restart it started up on it's own and mounted. What super luck! I was able to transfer all of my work onto the new drive without a hitch. I also found that is very important to read directions pertaining to the proper way to connect a jumper connector on the back of a drive when using multiple drives with an ATA card. I don't trust the Maxtor drive anymore now, so I will just pull it out of the machine. Thanks for the tips Noble B!

Serial ATA internal drive not mounting to desktop

I installed a serial ATA Seagate Barracuda 7200.9 Hard Drive - 300GB in my G4 MDD. I had previously installed a 120GB Seagate SATA drive into this same computer and it was immediately mounted onto the desktop after rebooting. However, that didn't happen this time. The drive installed easily but it is not mounting on the desktop. It is attached to the same PCI card as the other SATA drive. When I open disk utility, it does not show up as a SATA drive but as an ATA drive and it says it is not S.M.A.R.T compatible. What have I done wrong in connecting this drive???? Any suggestions would be most helpful
Dual 1.42 Ghz PowerPC G4 Mac OS X (10.3.9) 2 GB DDR SDRAM

Hi
If I remember correctly Seagate initially shipped the 7200.9 drives with something called Spread Spectrum Clocking (SSC) enabled. This isn't supported by most PCI SATA cards (or inbuilt SATA controllers come to that) and the drive won't work. I think Seagate made a utility available to switch if off, but it was Windows only and the drive had to be installed in a PC first.

10.4.7 & FireWire drives not mounting

Hi everyone,
since this morning my trusted LaCie FW HDs won't mount, are not seen in System Profiler and Disk Utility.
I tried almost every thing I could find, resetting vram, pram, powering everything down, waiting, disconnecting all the cables, powering back up, connecting one after another, etc. - no changes.
Every application runs fine. Except, of course, Logic because I have all my sounds and song projects on these drives.
My system.log continues to say every second again:
...-Computer kernel[0]: AppleFWOHCI_AsyncTransmit::waitForDMA - context not going inactive.
The console.log repeats:
-Computer root[175]: [MAFL] attempt to make FSSpec for "121-210.cypress" failed -120\n
-Computer root[175]: [MAFL] attempt to make FSSpec for "210.cypress" failed -120\n
-Computer root[175]: [MAFL] found no firmware to load for 210\n
Does anybody know what these logs mean?
Is anybody else having this problem with 10.4.7?
I started a similar thread on A-S-D- Installation and Setup, only to find out, that a lot of people there are experiencing the same issue (FW drives not mounting, not showing).
Would resetting the PMU help?
Please help, I can't work

Back from the mysterious world of HDs, so easy to solve..., sometimes...
I tried the HDs on my friends older PB and all was fine.
Resetting my computers PMU did not solve the problem, after I tried everything else.
I refrained from reinstalling 10.4.7.
All other applications (but Logic, because I could not access my files) were running smooth.
Going back to 10 a.m. yesterday, basically starting over, there was one thing I missed checking (being human): the AC to DC converters supplied by LaCie for their drives.
See, they are under my desk, like out of sight...
Voilá! Individual testing revealed, that the AC/DC converter for the first LaCie drive in my chain did not spin up any of my other six LaCie drives, which I never run all at the same time, but they still have their own power supply.
Changed power supply on the first HD and now I am back to the fast speed and glitch free system I love. Back to enjoying work as well
What a day. And I am very sorry, that I was implying to blame 10.4.7 for this. My PB has never been faster

SOLUTION - USB 3.0 External Drives Not Mounting on MBP Retinas - SOLUTION

So I have been having the same problem as everyone else who has issues with USB 3 external hard drives not mounting on their MBP Retinas. My friend told me to try unplugging the USB cord and plugging it back in instantly (like in half a second, so as to not let the power turn off on the drive). I had my doubts but then I tried it just now, and MY DRIVE MOUNTED.
GO TRY IT AND SEE IF IT WORKS FOR YOU!
UPDATE: I am using a powered external drive (Seagate Backup Pro 3TB). Not sure if this will work with bus powered drives, but I think it might, as my friend might have been using a bus powered drive.
Also, I just bought two Hitachi TOURO 750GB bus powered portable drives (7200rpm/USB 3.0) and they mounted perfectly without problem as soon as I plugged it in for the first time.

Did you unplug the USB cable from the computer or from the external drive? This fix has been posted here previously but it was reported that the cable had to be unplugged from the device, not the computer. If the cable was unplugged from the computer instead, the fix didn't work.

Internal hard drives not mounting on startup

Problem: I recently did a clean install of Mac OS X 10.8 Mountain Lion on my Early 2008 Mac Pro. Since then, one or more of my four internal hard drives will not mount at startup, and it's seemingly random which ones will or won't mount; it differs from one startup to the next. Obviously, the boot drive starts up, but the remaining three drives are hit-or-miss.
Troubleshooting So Far: I can open Disk Utility and mount the disk(s) manually, and when I click Verify Disk, the hardware checks out okay. After my most recent startup, I brought up the System Log in Terminal (sudo syslog -B) and found this entry for one disk ("Media 1") that did not mount:
Apr 25 10:40:09 new-host-2.home fseventsd[48] <Critical>: event logs in /Volumes/Media 1/.fseventsd out of sync with volume. destroying old logs. (454 0 68038)

There were no entries for the disks that mounted correctly. Can anyone make sense of this for me? The system jargon is a little beyond me.
Thanks for your help!

Is "Media 1" the name of the volume, or is it just "Media"?

Internal Hard Drive Not Mounting

Hi,
I've recently had a problem with my 2009 Mac Pro 8 core. One of the internal drives didn't mount or show up in any of the menus/disk utility. I tried moving the drive to another bay and it then mounted correctly. I installed other drives in the same bay and none of them show up so I presume there is something wrong with that particular bay.
I have a feeling that a trip to the Apple Store is needed but as I'm not particulary weathy at the moment I was wondering if anyone had had any similar problems. I've read on another thread that sometimes the connection to the motherboard/power can come loose but the information on finding it and plugging it back in properly was for a Mac Pro 1.1 (different internal layout).
Any help would be greatly appreciated.
Thanks
J

Hi,
Thanks for the reply. I've finally managed to pick up some compressed air and have a look as you suggested. Doesn't seem to have made a difference though.
I guess I'll have to pop it into Apple for them to have a look.
Thanks anyway

How do I make an internal hard drive not mount at startup?

I have an internal hard drive hooked to an ACARD ATA RAID controller that I use for backup purposes, and I would like to mount and unmount it manually. Disk Utility in OS9 and earlier had an option not to mount a disk at startup, but I see no such option in OS X.
I can manually unmount the drive in Disk Utility, but it always comes back up when I reboot. How can I keep the drive from mounting upon reboot?

I discovered this in a quick internet search.
http://www.macseven.com/files/20070719how_to_prevent_a_drive_volume_frommounting.html
Please note that I have never personally done this and am not recommending it. But maybe it will give you some guidance.

Internal boot drive not mounted -- Mac does not restart

Hi everyone,
I've got a problem with my 2013 MacBookPro 13" with OS X 10.10 Yosemite.
It seems that somethings wrong with my internal boot drive. I wanted to start my Mac but the grey progress line stopped at about the half and didn't continue. I tried to boot in secured mode --> not possible. I loaded recovery mode and wanted to check and repair disk utilities but I cannot hit those buttons because my drive is not mounted and cannot be mounted. I also tried to connect my Mac via Firewire with another Mac in Target Disk Mode --> Drive could not be mounted. Finally I tried to mount my drive on a Windows and Linux computer --> not mounted :-(
Is there another possibility to mount my drive or to access my data somehow? The thing is that I do not have a backup and that is why I need to access my data and store them somewhere prior being able to do a clean reinstall of my Mac.
Thank you for your support.
Markus

Boot into the Recovery volume (boot with the Command + R keys held down), select Disk Utility and try to repair the disk and disk permissions. If you're able to reboot normally and see that works.
If not reboot into the Recovery volume and reinstall the system.
If you can't boot into the Recovery volume mamau08 may be right in that the drive has failed.

Internal / External drives not mounting.

Hi All,
I have a Mac Pro Early 2008 that has suddenly developed the problem of not showing any of the three internal hard drives or any of the connected external drives on the desktop. The system drive does appear. This is a recent development but did not happen immediately after installing 10.6.
Potentially related, I can not shut down (also recent) without forcing to with the power button. Also takes an extremely long time to power up. Five minutes or so.
So far I have attempted repairing permissions, restart, resetting the SMC, and none of these have fixed the problem. Any suggestions greatly appreciated.

Just some of my experiences:
Checkmark got lost in Finder's Pref dialog for "show drives" "show external drives"
External drives got corrupted since I turned the power off the very second the drive-symbol disappeared from my desktop = I learnt that the drive is still doing some cleanup though it does not show anymore. So give it another 30 seconds before disconnecting its power supply
Luckily I had a backup since I always run TWO backupdrives parallel as a kind of mirror. So I reformated the corrupted drive and had the same problem. Somewhere in this forum I found that a slight change in size forces Apple's drive-utility to REALLY clean up everything from scratch. So I change the partition sizes by 1MB ... now no problem anymore.
My internal drive with OSX 10.6 has also been starting very slowly. I found out that removing as many as possible caches incl. the image OSX saves whenever you close the MacBook helps. Some of that cleanup was done using TinkerTool Systems and Onyx. Others was done manually. I also deleted many preference and .plist files like those of safari or preview
Finally I deleted all stuff which might initiate time-consuming internal communication ... no automatic check for updates. All programs needing "SIMBL" and Bonjour had to go. I had forgotten some test-entries in my networks systemprefs which made the system look for network connections. It goes without saying that any "connect automatically at startup" should go as well. I also had the spotlight index redone. Microsoft's Entourage Database was also checked and compressed. At the end I checked everything with Apple's disk-utility, DiskWarrior and Onyx. Now I am back at about 50 seconds for start-up
By the way: I deleted all 20 or so RSS-feeds and removed all widgets which depend on external information (like weather, airport departure). Funny enough - since then I also have no hang-ups experienced, whenever Safari is open. Since all these little workers update in different intervals I suspect that sometimes, their updating adds up and block the MacBook for 1 Minute or so.

Hard drives not mounting properly

Lately my MacBook Pro Core Duo 2.4 GHz, OS X 10.5.8 is having trouble mounting hard drives. If I start from my external drive the internal drive may not mount on the desktop or mounting may take a minute or two. Disk Utility will see it but the Mount option is grayed out and I shouldn't have to use that anyway. Similarly, if I start off the iternal drive the external drive may not mount, or mounting may be delayed by a minute or two.
Also, drives appear inconsistently in Startup Disk Prefs or the Finder Window Sidebar. They may not show at all or be delayed in showing up.
First Aid reports no problems with the drives, I have a fresh install of 10.5.8 on my internal drive, permissions have been repaired, directory rebuilt with Disk Warrior 4.1 and the drive optimized with Tech Tool Pro 6.
This and the fact that Boot Camp will not launch are making things difficult for me.
Any suggestions? Thanks.

I have that when using an iMac at work - my external is an old FW400 Formac drive.
Tracked it down to when VMWare Fusion is running - it seems to arbitrarily 'seize' new devices, and then doesn't know what to make of them because they're HFS.
If I connect it either pre-startup, or before VMWare starts there's no problem.
Do you have something running which is grabbing/affecting your Firewire bus - check the logs in Console.

Hard Drives not mounting

Hi there...I have a QuickSilver 2001 G4 Tower with two internal 60GB HD and one External Wester Digital 120 GB HD which is my boot drive. For a few weeks my internal hard drives would sometimes mount and sometimes not. Now they completely are not showing on the desktop or in any Disk Utilities I have. I examined the ribbon cable and notice that it goes right over the hinge on the G4 door to access the innards of the Mac. There seems to be a dimple in the cable as well as a break in the cable right in one of the cable strands. It is about 1/8" to 1/4" long.
Thinking I had some file issue I did a files system check (command-S, fsck, etc.). Before it ran the file check, One of the lines read:
IOATA Controller Device Blocking BUS
My assumption is that the break in the cable is preventing the signal from getting from or to the drives. Could this be the problem.
Also, my son picked up a seagate 60 GB Hard Drive from a friend that was formatted for a PC and had a ton of software on it. On the chance It might work, I hooked it up to the extra power cable and used the ribbon cable. Now the interesting thing is that it worked. Hole in the cable and all. The only thing I did not do, now that I think about it, was to try the other connector of the two head ribbon cable.
My question is: Is there any way to install this other HD inside my case without going though an interal SCSI bus?
Also, is there a way to get around the 128 GB limitation of internal drives. From the system profiler, my machine has these specs:
Machine Name: Power Mac G4
Machine Model: PowerMac3,5
CPU Type: PowerPC G4 (2.1)
Number Of CPUs: 1
CPU Speed: 867 MHz
L2 Cache (per CPU): 256 KB
L3 Cache (per CPU): 2 MB
Memory: 1.5 GB
Bus Speed: 133 MHz
Boot ROM Version: 4.2.3f1
Serial Number:
Any Help would be appreciated. Thanks

John...your help has been...well, HELPFUL! LOL
Another question. I have been doing video editing and DVD creation with the Apple Pro Tools...however, my machine is only a 867 mHz and I have limitations on using Motion and HD DVD creation. I have seen much discussion here about processor upgrades. I was wondering if you had any suggestions on that subject. I am kinda partial to Sonnett Technologies hardware. But I want to be sure it will work with the Pro Tools since I have read that some have had issues with some processor upgrades.
I also have a UMAX S900 clone which has a Sonnett Technologies upgrade card which has worked flawlessly (btw, I use the UMAX for all my system 9 work. I figure why clog up my G4 with all that other stuff? I have installed all my System 9 programs including PageMaker 4.2-- wow! I was surprised when that installed!). I had some old files in PageMaker 3. or 2 or something and could not open them with InDesign or Quark or PageMaker 6.5. I looked in my disk storage case and, lo and behold, my original back-up floppies (remember those) when I bought the 4.2 upgrade. Man did that bring back memories-- swapping disks to install-- SEVEN OF THEM!
Once again, I appreciate your help and hope you can supply some additional insights. I am going to pop off those connectors on the internal hard disks and reinstall...maybe something is just loose. I am not thinking it is the controller on the board. If it was, the PC disk would not have mounted...right?

WiebeTech Super Desktop Drive not mounting in Tiger

Hello,
I have a wiebetech super desktop GB external firewire drive. Originally, I used it with OSX 10.2. That was a few years ago. It worked well then.
It worked much the same with 10.3, except that when we tried to mount it, nothing worked, except it you plugged the firewire cable into the back of the iMac at just the right time: when the drive made a 'ba ba' noise.
And now with 10.4 tiger, nothing seems to make it work. Here is wiebetech's advice (note: I inserted a little note next to the steps I've tried):
2004-11-09
Mac OS Updates
A new OS update was released and you installed it. As with nearly every OS update
Apple does, some external drives are not recognized after the update. The incidence
is fairly uncommon and the most common symptom is that the device will not mount
but the volume is visible and greyed out in Disk Utility. This means that the
device is working properly, but the OS does not recognize the volume as mountable.
Sometimes the drive does not show up at all. Now this happens to every drive
manufacturer but not to every drive. There is no discernable way to prepare for
this and no one thinks about it unless it happens to them. So now what?
The first thing to do is to see if repairing Disk Permissions with Apples Disk
Utility First Aid feature solves the problem [tried this]. If not, try Repairing the disk
with First Aid. Another possible solution is to ZAP the PRAM [tried this too]. For the older Mac
users, this is the same from the days when we manually rebuilt the Desktop and
is done with a keyboard command while rebooting. Restart your computer and hold
down the Command, Option, P and R keys. Consult the Apple web site for details.
If this does not work, then try pushing the PMMU reset button on the logic board [say what?].
Consult the Apple web site for locations of the button for your Mac. If the drive
still does not show up, shutdown, disconnect all peripheral devices and boot
from the Mac OS Installation CD. The later the OS version, the better. Do not
reinstall the OS, but when the Installer is loaded up and ready to begin, go
to the File menu and use the Disk Utility program. Connect the drive that is
having problems, then start the Disk Utility application. If you see the external
drive and it is not grayed out, you know the drive is okay. But run Disk First
Aid on it anyway. Then run it on your internal boot drive while you are at it.
When done, unmount the external drive and UNPLUG it! Then restart the Mac.
When the Mac has restarted and is running on the internal boot drive, reconnect
the external drive.
As you can see, I'm having some trouble here. Anyone have any suggestions?
Thanks,
ben

Forget this enclosure:
Vantec Nexstar LX 3.5 Network Attached Storage NAS Enclosure
Do not bother to buy it. Waste of money and time. When I looked at it I thought that someone is copying someone elses ideas because even electonics seem to be the same as in NewerTech units. Anyway it has more problems and defective pieces are common on the market. It is also noisy as it runs fun. Why they cannot figure out that plastic enclosures will always have cooling problem while one decent piece of thic aliuminium like in MadDog, LaCie or even some cheaper enclosure may be better and not always require noisy fan. I run MadDog enclosure now with up 500GB drives in them 24x7 no fans (do not stack them and leave gaps between them if you want to do this!). Also some could figure out that radiators have their shape for reason and the idea can be implemted to some degree in enclosures too.
