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.

Please note that I have never personally done this and am not recommending it. But maybe it will give you some guidance.

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"?

WD hard drive not mounting on startup...

Grrr! This is driving me nuts! I have a WD MyBook Essential 2.0T USB hard drive connected to my iMac 27" i7, and every time I reboot the iMac, the drive fails to remount. Disk Utility doesn't recognize it, either. My only option is to disconnect the USB cable and then reconnect it. The drive then shows up. But pulling a cable is so very not an acceptable solution! Don't think data can be corrupted if the drive hasn't mounted, but still....
I have four other, older WD drives and none do this. I had a more recent WD MyBook Essential drive that also wouldn't mount on startup on my old MacBook Pro, wouldn't take the updated firmware, and kept corrupting files, and I ultimately replaced it with this new 2.0T drive shortly after getting the new iMac. But even with a new drive, new iMac, and different cable, I still can't get the WD drive to mount upon reboot. Arrggghh!
Has Western Digital done something different with these newer drives? How can I get this thing to mount after a reboot?
Thanks!

Western Digital has been playing with their firmwares for years. They keep trying to maximize power efficiency to anticipate when the computer will use the drive and shut it down when it's not required. This isn't really a good thing for Time Machine, and I don't want any vendor to constantly change their firmware for their purposes. Many other companies seem to be able to build drives that just work.
I've updated the firmwares on many of these drives for clients because they performed so flakey with both USB and Firewire. I think there are problems with the firmwares being designed to maximize power consumption at the cost of not being always ready for Time Machine. Some of the WD firmware is actually on the drive itself, not the interface chipset, so problems return when you swap out the drives in the cases...
In addition, I have no need for all of the freeware/backup programs and other features they junk up these drives with. I just want reliable drives for backing up files, without having to uninstall their embedded programs. I found this review that pretty much sums it up for me: http://www.amazon.com/review/R1FBX79QK9IR9N/ref=cmcr_prviewpnt#R1FBX79QK9IR9N
Looks like you've been burned twice by their eager, innovative engineers.

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 a bootable hard drive clone of my main disk in my mac pro?

Hi everyone,
How do I make a bootable hard drive clone of my main disk in my mac pro?
My main drive has bad sectors and I want to replace it.
Thanks in advance

Also your Mac's Disk Utility can make a bootable clone;
http://macs.about.com/od/backupsarchives/ss/diskbackup.htm
Consider though, if your internal HD is failing and defective, then any clone however made, may carry that defect.
Perhaps it would be better to copy your personal data, photos emails etc, to an external drive as well, just in case the clone did not work because of the failing hard drive.

How do I format a internal Hard Drive from a PC/laptop

How do I format a internal Hard Drive from a PC/laptop...My old internal hard drive had problems so I took it out and I have a 100 gb Seagate ATA drive that I replaced it with. In the mean time I've been using a external drive to boot up my powerbook g4. Not sure of what to do.

Hi, capitala1. Start your Powerbook up from your Mac OS X installer disc and open Disk Utility from the Installer or Utilities menu (depending on which OS version it is). Select the newly-installed Seagate drive inside your Powerbook as the target, and format it "Mac OS Extended (Journaled)". It makes no difference at all that the drive came out of a PC laptop: this is exactly the same procedure you'd use if the drive had just come brand new from its manufacturer.

How can i get an internal hard drive cable replacement?

how can i get an internal hard drive cable replacement?

I believe iFixit sells them:
http://www.ifixit.com/
You can also go to an Apple store, they won't sell you the part, but they will replace it for a fee.

Which brand makes good internal hard drives?

Which brand makes good internal hard drives?
I will probably want serial ata 5400rpm, but don't know which brand to trust.
I have had a bad experience with Seagate failing on me.
Any suggestions? Primarily, it will be for mirroring my initial drive, as a backup.
thanks!

There are four drive bays, so keep an off line backup, but I think you'll want one for Time Machine, one for data, and one for system, if not today, eventually.
Then comes the level of storage and performance, and price. You can pick up a nice WD SE16 500GB for $99 at OWC for their Friday/weekend special. Then go from there.

How do I replace my internal hard drive and not lose windows partition?

Hello,
I am wanting to swap my internal hard drive out for a larger one. What do I do about my windows partition? I only use boot camp, and there is some stuff on my windows side I don't want to lose. I know how to make a clone for OSX, and I know how to replace the actual hard drive, it's just the windows that I am a little sketchy on.
Thanks for your help.

WinClone - check the faq and forum for tips and read the docs
http://www.twocanoes.com
Pull your hard drive and put it in external case, OWC sells such kits, you could probably use a good windows clone program too.
but you need room on an (external) hard drive to hold the Windows image (uses a sparse disk image file is all).
Paragon Software has been busy releasing programs and updates to help Mac users running Windows, using NTFS (and EXT2/3), as well as CampTune (free for now) for resizing Windows or linux boot camp partitions.

How can I replace my internal hard drive on my Macbook?

I have a 13 inch aluminum late 2008 MacBook. The processor is 2 GHz Intel Core 2 Duo, Memory 4 GB 1067 MHz DDR3 running OS X Lion 10.7.4. The hard drive is currently set up as follows:
Macintosh HD 132.5 GB (with only 1.32 GB free)
BOOTCAMP 26.69 GB (with 6.15 GB free)
I am unsure if this matters but here is the info just in case:
On my Macintosh HD I have:
Audio 3.04 GB
Movies 33.11 GB
Photos 36.98 GB
Apps 15.27 GB
Backups Zero GB
Other 42.78 GB
I only use 1 software program on my Bootcamp (which I hardly use but must keep to run an electric vinyl cutting machine). I have thought of re-partitioning the drive. But then I got thinking that maybe the drive is just too small and it's no use.
I also have an older Lacie 300 GB external hard drive that I use to keep all of my iTunes Library, most of my iPhoto library and most of my data. I have another older Lacie 300 GB external hard drive that I use exclusively for my Time Machine back ups.
I also have a Western Digital 2 TB external hard drive that I use to put all of my movies on so that I can play them on any of my computers or plug into my Play Station 3 and play them on any of my TV's.
I have considered just getting another Western Digital 2 TB external hard drive to use for virtually all of the files/pictures/movies/music etc. on this internal hard drive.
Right now I am unsure what the best move is to make. I spent 30 minutes on the phone with Apple Tech Support today trying to buy an internal hard drive to install myself. They were not very helpful (in fact he told me I would have to ship in my machine just to replace the battery which is NOT true). Is there anyone out there who can give me some advice on this situation? Any help or suggestion would be appreciated.
Thank you in advance.

For a new hard drive try Newegg.com http://www.newegg.com/Store/SubCategory.aspx?SubCategory=380&name=Laptop-Hard-Dr ives&Order=PRICE

Here are video instructions on replacing the hard drive on the Aluminum Unibody http://eshop.macsales.com/installvideos/macbook_13_unibody/
To transfer your current hard drive I like the free application Carbon Copy Cloner. It makes a bootable copy of everything on your hard drive http://www.bombich.com/index.html You'll need a cheap SATA external hard drive case. Put the new drive in the case then format and partition the new drive and clone your old drive to the new one. Check that it's set up right by booting up from the external drive. Then replace your old hard drive with the new one and put your old one in the external case.
Here's a cheap SATA external hard drive case on Amazon. http://www.amazon.com/Drive-Aluminum-External-Enclosure-Capacity/dp/B000XPS3U6/r ef=pd_cp_pc_3
If you don’t have the tools to open up the MacBook OWC has a set for $5

How do I fix my internal hard drive stalling all the time??

Hello,
I have a few hard drives attached to my G5.
2 external and one additional internal.
My issue is with my internal drive. It's a 750 GB drive.
if ever I return to my computer after being away for more than 15 minutes, every time I try to access something on that drive...meaning, I cause it to wake up. It stalls and I get the spinning beach ball forever. till most time I have to force shut down my computer.
So if I happen to be working in any softwares I use and try to open a file in that software that is on that drive ....it stalls. If i'm in my finder and happen to have a window open, 3-4 folders deep into that drive. when I click on a file in that window ....it stalls.
the only time it doesn't, is if I'm in finder and close all the windows and THEN click on that internal hard drives icon then it opens normally.
So it's ONLY when I try to wake the drive up does it stall. never have any issues when I'm just working away normally.
this is my second drive and had something like this going on with the previous drive too. when I was running. OS X 10.2-10.4
so I'm pretty sure it's not the drives that are faulty
Is this a known issue? are there any fixes??
if anyone can help that would be great thank you

Not a solution, but something to try.
In the Energy Saver preference window, do you have the "Put the hard disk....possible." checked or unchecked?
Try it the opposite of what you have selected now.
Also, do you have the same problem if the energy saver is moved to Never?

How do I make my external hard drive show up in devices even when the external discs box is checked in preferences?

External hard drive not showing up in devices, even after troubleshooting and checked in preferences.

OK I solved my own problem. My iPhone was plugged into the other USB port in addition to the external hard drive. I took out the iPhone USB and switched the external hard drive USB to the other USB port. The drive showed up in my devices!

Pavilion g6 internal hard drive not working , Can I use WD internal hard drive ?

I have pavilion g6 series laptop . I don't know RPM .
HP internal hard drive is looking very costly.
Can you tell me whether I can use WD internal hard drive or not . If yes then How much RPM hard drive I need to buy?

Hi,
We won't concern about RPM, faster (more rpm) is better. The HDD's are much, much, much, much cheaper now. They were more expensive during a flood in Thailand few yours back. Yes, you can use WD HDD for your computer. You can pick one from the following list:

IMac G5 Internal Hard Drive Not Recognized

I shut down my iMac G5 with the power button and not through the typical shutdown procedure once and then when it booted up it would not get past the gray screen. I eventually used the Leopard DVD to try to boot it and was able to get to disk utility to look at the drive. I tried to repair the drive but then the machine froze and I had to restart once more. Now the internal hard drive isn't recognized or seen at all. I actually switched out the SATA hard drive with another spare I had and that was not recognized either. I can get the mac to recognize the installation DVD still so I know my computer still functions properly but I just need it to recognize the drive now. Does anyone have any ideas how to resolve this?

Have you access to DiskWarrior or TechToolPro? Either of those might fix your problem otherwise, try booting from the Apple Hardware Test on your install disc and see what it says.

Internal Hard Drive Not Appearing in Finder

I just had to do a reboot of my Mac Pro as Final Cut Pro kept locking up and when the computer was back up, one of my Western Digital 2 TB internal hard drives is missing! When I restart, I got a message saying something like the disc inserted cannot be used. It had 3 options and the first time I hit eject thinking it was talking about a DVD, then when I rebooted again I hit the details button and it pulled up Disk Utility. I can see my HD in the menu but when I click on it is says unmounted. The other 2 TB WD Hard drive is working fine. Do I need to click on the verify disk or repair disk button? What should I do? I have quite a bit of video footage on this drive that is missing so I'm super worried I will lose the videos!

The drive is a goner otherwise though. Since I was solely using this failed drive recently, I may have just worn it out, which is too bad, even though I worked with an identical 2 TB WD internal drive earlier this year and never had problems with that one.
Drives shouldn't just wear out from use, at least not in a reasonable number of years. They are designed for that. Drives however do fail. However, that drive is more likely to be badly corrupted than it is to be mechanically failing. When you are finished grabbing the data off it, use Disk Utility to zero it out. If it can successfully be zeroed out then it is most likely fine to continue to use.
