Eject Firewire Hard Drive, Won't Stop Running

I upgraded my Early 2009 Mac Pro OS to 10.9 today, but I found a problem about my external firewire hard drive.
If I eject firewire hard drive under 10.8, the hard drive will stop running/rotating. Then I unplug the firewire cable. After I upgrade to 10.9 OS, the firewire hard drive will not stop running/rotating after I eject it. I cannot see any external hard drive icon on desktop, but I can hear the hard drive running sound.
I'm not sure if it's safe to unplug cable under running condition after succeful eject. How's many people have the same problem with me?
Thank you!

I have a dozen OWC cases and they have all continued to work (but can't say about 10.9) and they are getting "dated."
Apple though often changes drivers, IOKIt and how external drives are treated, 10.5.0 thru 10.5.2 the rules changed and changed back and forth. Some drives had to be off during startup. Users have had trouble with 10.6 as well with their drives, often USB and/or FW from major vendors (WD etc) not working.
Do either of you get the "drive was not ejected properly" message on the next time you do connect and power it back on or after a restart?
One of the reasons I prefer waiting for the .2 or later releases.

External Firewire hard drive won't mount after 10.4.10 update

I see many posts about USB drives not mounting after 10.4.10 update. Just lending my voice to that issue (my USB drive won't work either) as well as the 10.4.10 update breaking Firewire drives.
Hope a fix is coming. No backups are scaaaary.

How to fix the problem of a missing external Hard Drive (Firewire) after it vanishes from you desktop after installing 10.4.10 update.
I have a iMac PPC (Non intel). Aparently my system upated installed the wrong version of 10.4.10 and thus my external firewire hard drives a 320 GB Westerndigital My Book, and Acomdata 80 GB, and aWestern Digital 160 GB media center all vanished from the desktop.
The instructions below should be credited to several different people. I found various version of these steps in the Discussion. I combines a few of them into this one 10 step fix and it worked for me. I hope it works for you.
1) Shut down you computer
2) Unplug all peripherals (i.e USB and Firewire, I left computer power plug in as well as ethernet and Keyboard+ Mouse) and leave along for 30 Minutes
3) Restart holding down the Command (Apple) + Option + P + R keys for three startup bongs, then release the keys and your computer will start up as usual.
4) Verify and repair disk Permission using Disk Utility. (Several things were repaired here)
5) Instal 10.4.10 Combo PPC
6) Restart Again
7) Again repair Disk permissions (None of mine needed to be repaired fyi this time)
8) Unplug Power cable and Firewire cable from External Hard Drive (leave along for 1 minute)
9) Reconnect power to Firewire External Drive first then the Firewire cable to the drive second, then the firewire cable from the Drive to the computer last.
10) Turn on your Firewire Drive... you will head it spin up and eventually show up on your desktop just like it did before the 10.4.10 update.

NEW Hard Drive Won't Stop Spinning

I just replaced my Maxtor 180Gb SATA HD with at Maxtor 500Gb SATA HD and the new drive won't stop spinning and there's a red light on inside the tower. Any ideas of how to fix this?

Is there any thing on it yet, or just freshly installed then booted up & getting ready to install?
Do you have a Mac Pro (Intel), or a G5 (PPC/IBM)?

Firewire hard drive won't mount - Filesystem verify or repair failed.

Hi all - over the last day my lacie hard drive won't mount - i have tried it on various computers with the same result
disk utility can see it but won't mount or repair it reporting the following error
Filesystem verify or repair failed.
any help would be appreciated

Try Disk Utility first. It's in your Applications/Utilities folder.
You'll want to select the disk in question, then +Repair Disk+ (not Permissions). This actually repairs the +File System+ that's on the disk.
If that works, you're ok, unless it begins happening frequently. Then you need to save up for a new one.
If DU can't fix it, then one of the others might. Disk Warrior is about $100, and many people here say it's the best. There are others for less money, but there's no guarantee that any of them will succeed.
You can also try just erasing it, and choose +Security Options,+ then +Zero Out Data.+ If that fails, or you have more problems with the drive, you need a new one.

Forgot to eject external hard drive-won't mount, doesn't show

Hello,
I just bought a great running G-Technology (500GB) firewire/usb portable hard drive to replace an older much less stable drive. I wanted to copy the files from one to another when the imac disc just stated spinning forever. Having experienced this before I tried shutting off the old drive, but to no avail. So I panicked and shut everything down. Obviously, I didn't eject the new hard drive. After restarting I was able to get the old drive to appear on the desktop but not the new one. It doesn't show in Disk Utility and I've tried going to Go/Go To Folder/type:/volumes and where the icon of the new drive doesn't show up. I've unplugged it, restarted the computer with and without the new drive plugged in. The new drive light is on and power seems to be going to it when plugged in. What to do? I hope I didn't ruin the drive. It's less than a week old. Thanks for any help! Kris

If you are trying yo use the drive's USB connectivity, "portable" could be the key word. Some drives that must get their power from the computer's USB port ("bus-powered drives") may not get enough power under some circumstances. Their counterpart is the desktop or "self-powered" external drive that comes with its own power brick.
There are workabouts for your existing drive if it lacks its own power supply:
1) Try a different USB port. Not all USB ports provide the same level of power. Ports on the keyboard should be avoided--they can seldom power even a thumb drive
2) Get a self-powered USB hub. It adds to the power feed for the drive and usually fixes the issue
3) Get a USB "Y" cable like this:
1 Meter USB 2.0 A to 5 Pin Mini B Cable - Auxiliary USB "Y" Power Design for external hard drives.
It uses two of the comptuer's ports for extra power.
If you are connecting with FireWire, then the drive is likely faulty.

External Hard Drive won't stop sleeping

This is really frustrating me. I have my settings unchecked to allow hard disk to sleep, also my computer is set to never sleep. However whenever I try to access my external drive, I always have to wait several seconds for it to spin up. It's as if OSX is ignoring my preferences and just putting it to sleep still. I don't understand. It's really annoying to have to deal with the lag of drive spin-up all the time. What do I have to do to get my external hard drive to NEVER sleep, so it's always immediately accessible? It's a Samsung Story 1.5gb external USB, not that it should make any difference...

Some external HDs respond to that setting, some don't. Some won't respond unless you disable the built-in sleep (or "spin down") software. As Baltwo says, check with the maker.

Hard drives do not stop running-HELP

I have noticed that, in the last day, my hard drive is constantly running (x resource graph)--which is highly unusual. It is a kind of a 'slow jogging' at 141k or so, typically 'writing'. So far, does not seem to have affected the computer much, but I am concerned as obvioulsy it should not be ocurring. I tried fixing priviledges, using console to identify any questionable activity, tried to identify unkown programs via activity monitor (the only thing I could identify was pmtool, but this was apparently linked to activity monitor itself). I do not know if it is a virus, but I do not think so. I have 2 internal hardrives, but my current utilites do not tell me which drive is running, and I am unable to identify what program is doing the writing. Any help, info, suggested programs to fix this glitch would be most welcome. It is driving me nuts.

I fixed it. Turns out that a screen saver program I was testing kept the hard drive 'humming' at a very low 'frequency'--even when it was not working per se. Bad product design. I quit the program, and...c'est tout. Finito. Mama mia. That's the last time I use that program! (I had forgotten I had 'turned it on'.)
By the way, unmounting my second hard drive was also a check. And, yes, I did restart...
Nontheless, many thanks for the kind (and very appreciated) suggestions.

"Applying privileges to external hard drive" won't stop?

I recently got a new MacBook and migrated all my data from an external harddrive to my new machine. I use the external drive also for storing my media, but since using the new machine I have to authenticate every addition/change to my media in the subfolders with my system admin password. I looked around and found in the drive info a section on Sharing and Permissions and selecting my account clicked "apply to enclosed items" thinking this would solve my problem (do tell me if it won't!). The process, however, is taking forever. I did something that might have been stupid, namely quit the process "locum" in the activity monitor as I assumed that was the application process. I then tried to "apply to enclosed items" again, but the process wouldn't start. I then restarted my machine and started the process for the third time, but it's now been over an hour and there's no sign of progress.
So my question is firstly, is what I'm doing going to help me with not having to authenticate every action in the drive subfolders? Secondly, is the length of the process related to the amount of data on the drive (I have just under 400GB) or is something going wrong?
Thanks very much for reading, I'd appreciate any help you might be able to give!

In the Get Info panel, there should be a box to "Ignore ownership on this volume" Check that box and you should then have full permissions.

New FireWire external hard drive won't mount: conflict with iSight?

My parents just upgraded their eMac (1 GHz, 1GB RAM) to Leopard and bought an external FireWire hard drive to use Time Machine. We got the drive back to their place, powered it up, and plugged it in via the FireWire cable. Nothing. Wouldn't mount, didn't show up in System Profiler or Disk Utility. We tried a few more times but eventually gave up and figured the drive was DOA.
After I got home, I realized I should have had them unplug their iSight and try again. Is the FireWire bus on the eMac balky enough that this one additional device could have caused a conflict? They're not using any FireWire hubs: these were the only two devices on the bus.
If it does work without the cam attached, is there then any way to get the two devices to play nicely together afterward? They use the cam all the time for videochats with family, so I'm not about to tell them they have to give that up just to get more frequent backups.
Thanks!

Thanks for your speedy reply. How appalling that a computer with two FireWire ports can't use two FireWire devices! And it's Apple's own device that causes the conflict. I can't even think of an easy workaround, since the whole point of Time Machine is that the drive remains connected all the time.
I guess I could have them eject the drive, unplug it, and connect the iSight whenever they want to start a videochat. If the eMac only had USB 2.0, this would be moot! D'oh.
I'm getting ahead of myself, though -- I still have to go to their place and try the external drive without the iSight attached. Thanks again for confirming my suspicions.

Hard drive won't read Disk, Firewire or Disk Utility

Everything with my computer seems to work fine on start up. However when I insert a disk, attach a firewire drive or try to download an update it fails. When I go to disk utility or try Onxy to repair permissions the programs runs forever and never sees the hard drive. Any suggestions?

Hi! This sounds like logic board or hard drive problems. Try running the hardware test disc that came with your computer or that may be on the install disc. Tom

External hard drive won't appear on my desktop

I'm trying to run a backup, but my hard drive won't appear on my desktop. I see it in Disk Utility, so I know it's there...
...any suggestions?
Thanks,
kevin

Kevin - There might be a few reasons as to why your external drive won't appear have you tried any of these suggestions:-
STEP ONE - Confirm that the drive is being seen by the system
Click the Apple icon and select About This Mac.
Click More Info.
Select the Drives and Volumes tab.
If the Iomega Hard Disk drive is not listed under the USB/FireWire arrow, proceed to STEP THREE.
If the Hard Disk drive is listed, continue with the next step.
STEP TWO - Format the Hard Disk drive to Mac HFS format
The Iomega Hard Disk drive is factory formatted to FAT32 for maximum compatibility. If you have not reformatted the disk or the disk is formatted to FAT32:
The disk may mount very slowly in OS X if the disk is FAT32 formatted.
Mac OS X will not mount any DOS (FAT32) partition larger than 128GB. For more information, please check the Apple® Web site at http://docs.info.apple.com/article.html?artnum=107483
Warning: Erasing your Hard Disk drive will erase all of the information stored on the disk. If possible, back up your data before erasing the hard drive. Mac formatted disks are not cross compatible with other operating systems, such as Windows®, without the purchase of additional third-party software.
Double-click the Mac hard drive icon.
Double-click the Applications folder.
Double-click the Utilities folder.
Double-click the Disk Utilities icon.
Highlight the drive in the left window.
Click the Erase tab.
Select Mac OS Extended.
Click the Erase button and then click Erase from the confirmation window.
If the Hard Disk drive now mounts, you are ready to use the drive.
If the Hard Disk drive does not mount, continue with the next step.
STEP THREE - Are the Mac OS X drivers detecting the drive properly?
The Iomega Hard Drive may not mount if you are using Mac OS X versions under 10.1.3. If you are not using Mac OS X 10.1.3 or higher, please visit the Apple® Web site at http://www.apple.com/macosx/ for information on getting the latest version.

Hard Drive Won't Mount After Repair by Second Computer

I have an G4 Cube with OS 10.2 on the internal hard drive (which is full) and OS 10.4 on an external La CIe hard drive (that I use as my main OS). The external hard drive accumulated serious damage that couldn't be repaired by Disk Utility on the internal drive. My copy of DiskWarrior X would not run under OS 10.2 (10.4 was required) and it wouldn't boot from the CD either So I connected the external hard drive to my second computer, an iMAC running OS 10.5. (Unfortunately, I disconnected the external hard drive when the computer was off instead of ejecting the drive by dragging it to the Wastebasket.) The external drive mounted and DiskWarrior easily constructed a new directory, defragmented the files, and eliminated all of the damage on the external hard drive visible to Disk Utility. However, when I reconnected the repaired external hard drive to the G4 Cube, the drive wouldn't mount. Privileges were repaired on both computers with the external drive connected without helping. Being repaired while connected to a higher OS or perhaps simply being connected to a higher OS seems to have left the LaCie external hard drive in a state which couldn't be mounted by an earlier OS.
Following this hypothesis, it booted the G4 Cube from the OS 10.4 Installation CD while the LaCie external hard drive was connected. When I cancelled installation of OS 10.4, I was asked to choose a start-up disk AND OS 10.4 WAS NOW MAGICALLY AVAILABLE ON THE EXTERNAL DRIVE. Simply starting up from a more advanced OS allowed the hard drive to mount.
Shockingly, when I restarted from OS 10.2, the external hard drive was still mounted. Whatever was preventing the drive from mounting was a TRANSIENT STATE, not backwards incompatability.
POSSIBLE LESSON: If a hard drive won't mount on computer A after being connected to computer B, consider booting computer A using the OS on the installation disk from computer B.

If you need to repair a hard drive with OS X installed on it, you must use that same version of OS X to perform the repair. Using another--in this case, newer--OS can cause quite a bit of trouble, as the directories/permissions may be dealt with differently between the OS's.
Seems you've learned this lesson--and luckily you didn't lose anything!

Lacie Hard Drives won't mount

My two Lacie hard drives won't mount on my G5 running Tiger. They were fine on my G4 iMac running Panther. I've tried using the Lacie Update Tool but the drives aren't recognised. I've tested the firewire cables on another drive that works and they're fine, so it's not cables.
Both drives power up okay and whir into action, but just aren't talking to the G5.
Lacie d2 HD 80GB FW DV
Lacie 40GB (no model number, "DESIGN BY F.A.PORSCHE", no model number).
Any ideas much appreciated.

This happened to me with a LaCie external drive as well.
The problem is that LaCie formats the drives as PC-based
and not Mac Extended, so unless you reformatted the
drives to Mac when you started using them, your access
to them on any Mac may result in a failure to mount.
Once that happens retrieval of data is made more difficult
because of this formatting incongruity.
There is no way you can get the data once your G4 quits
mounting them. If you can get the data off of the drives,
back it up and then reformat the drives using Mac's Disc
Utility. Then you can reload the data and I suspect all of
your Macs will then mount the drives via Firewire.
Good Luck!

Fan won't stop running

Early 2008 27 inch iMac running latest version of Lion.
I had a hard drive that kept corrupting files (not the original HD, been replaced once by apple) so I replaced it with a new (ish) 1 Tb WD green. But after I did this my fan won't stop running. I thought I had disturbed the HD temp sensor so I opened it back up again and made sure it was properly on the HD closed it but still constant fan.
from istat pro I'm getting readings
HD 37
CPU 29
CPU heatsink 28
Airport Card 30
GPU heatsink 33
HD Bay 38
Mem Controller 29
Optical Drive 30
All my temp values are there, so I assume my sensors are fine. I don't have AHT as I don't have my original install disks (I lost them somewhere in the last 7 moves between houses) I already tried resetting the SMC.
Can anyone tell me if these readings are normal? Are any high that would be causing my fan to stay on?

Um, OK. I've just realized that the fan isn't running any more, and I've been using it for a couple of hours. I'm not sure if I should do anything else or just not look a gift horse in the mouth. Anyone have an opinion?
