OS X :: External HD Not Mounting - Waiting For Root Device

Jan 3, 2010

My Macbook Pro 2.4 got force restarted a few times because it was locking up (a friend's faulty external drive I was trying to fix). It was running fine, then when I tried to connect my own external drives they wouldn't mount anymore and I got this error:
/system/..../IOStorageFamily.kext was installed improperly.

I came here and read up on common solutions. I have:
- Ran Disk utility repair and repair permissions
- Followed this article: [URL]
- In verbose and single user mode all I get is the dreaded "waiting for root device" over and over. They all have not worked so far. However in safe mode it actually boots. It seems to me that some drivers were perhaps corrupted when I turned it off abruptly and now it has trouble mounting any drive. What are my options at this point?

OS X :: External HDD Not Mounting On Boot

Feb 20, 2009

I have an annoying problem; I have 2 x 1TB Seagate daisy chained and then connected by FW800 to my iMac.

When I do a fresh boot up (in the morning usually), the hard drives don't automatically mount, I have to take the FW plug out and put it back in again.

OS X :: Not Mounting - Recognizing External Hdd

Mar 30, 2009

I have a 2.4 Ghz MacBook that i bought last summer, and a 250 GB Western Digital external hard drive (powered by computer) that i also bought last summer.

My problem is that My computer will not recognize the hard drive at all. it doesn't show up anywhere, and after attempting to reconnect it over and over, it will eventually pop up, and then disappear, saying that it was improperly ejected.

OS X :: External Drive Not Mounting After Use On PC?

Nov 5, 2009

I am using a macbook pro with 10.5.8, and have an external hd (freecom 320gb). I have used it for around a year and it is almost full. The other day, after attaching it to a pc - when i now attach it to the mac, it does not mount, and the warning 'this disk is not recognised' etc comes up. It shows in disk utility, but does not allow me to verify/mount it. I'm guessing the pc has reformatted it or something

What can I do?! I have looked into data rescue software, but I'm not sure - the information cannot just disappear? and I just want the drive to have the same architecture, as all my music etc was organised in particular folders.

Hardware :: External HD Not Mounting On 10.2.8?

Mar 8, 2008

I have a WD Mybook Studio, 500gb which I normally hook up via Firewire or USB to my Intel Macbook, 10.4, no problems. But that macbook's unavailable for the next week or so, so I dragged out my old Powerbook G3 laptop, running 10.2.8. Which can't seem to see the Mybook drive - hooked up via USB 1.0 cable. The drive is formatted HFS+, split into 4 partitions.

The My book drive hooks up fine and functions perfectly connected via USB (1.0) to my even older Mac 8600 tower!

The Mybook drive shows up in the System Profiler, and in Disk Utility. But the partitions are greyed out, and I cannot mount them. I ran disk utility on the mybook, and all drives verified ok.

I ran disk utility on the powerbook's boot HD as well - more than once, with repeated errors.

I know a little bit more than zip about terminal commands - I'm hoping this is something I can fix fairly easily, because all my data's on the mybook, and it would be nice to be able to have easy access to it this week..

Intel Mac :: External HDD Not Mounting On It With 10.7.4

Jun 14, 2012

It's a weird problem ,I got a iomega external drive usb3/2 compatible on my iMac white, Intel Core2 Duo 2.12 It's quite nw and always worked well.I have 2 partitions

1. iPhoto Library and music (mac partition, just mac)

2. Time Machine Backup

Since a while I got Time Machine errors but I didn't bother too much, now I discovered that the drive is visible but not mounted.

Investigated a bit with no results mounted on another macbook works just fine and all my stuff is there.The drive has additional cable for power (never used) I connected it without good result.Started in recovery partition and ... all my backup is there and visible and recoverable Seems however that backup stopped when I was on 10.7.3 I think 10.7.4 might be the cause but I don't know how to solve the issue and would avoid to restore via time machine and then get stuck again with 10.7.4

[code]...

OS X :: Couldn't Eject External, Now Disk Not Mounting?

Aug 15, 2009

I know this has been disccused ad nausium many places, but in reading 100s of posts Ive just confused myself and was hoping someone could help me make sense of all I've heard.I have a ibook g4 and use a WD 500gb external hard drive to keep all my music/pictures etc.Last night when I was moving files around (I dont think it was actually in the process of transferring files when this occurred, but there is a slight chance it was) I accidently hit enter instead of shift which told my computer to open all of the 1000+ folders that I had selected (DOH!) after working for an hour it seemed to be all frozen so with concern I turned the computer off and restarted.Suprise suprise, my external will no longer mount. - Disk Utility recognizes it but says there was an error on exit.Tim

Hardware :: External Hdd Not Mounting After Sleep Mode

Jan 6, 2010

I recently purchased a WD My Book Studio 1TB to use as back-up drive, using Time Machine.

After my iMac (Intel 2007 - Leopard) wakes from "Sleep Mode", the WD My Book is always dismounted so, unable to perform the Back-up ? I have to manually mount the drive before manually performing the back-up.

How can I keep my WD HardDrive mounted at all time, even after Sleep mode, so the Time Machine Editor automatic weekly back-up works ? Interface is FW800.

Hardware :: External HD Keeps Mounting And Unmounting For No Reason?

Feb 28, 2010

I am running a 2007 Imac. Version 10.5.8. 2.8 GHz Intel Core 2 Duo. 4 GB 667 DDR2 SDRAM and am using my Macintosh HD as my Startup Disk.

I have been starting to have some issues with my external hard drive (500gb Western Digital, connected via USB and power supply).

I've never had a problem with it before, but now it seems that when it "mounts", it stays connected and workable for about 30 seconds and then it unmounts and dissapears and I get a "bad device removal" message.

I don't want to lose anything on the HD so for now I just turned it off. I am planning on using DiskWarrior to attempt to repair it.

If, for instance, it is "fried" and cannot stay mounted, is there any way I can transfer the info onto another HD?

Hardware :: WD 500 GB External Hard Drive Not Mounting

Apr 24, 2010

I bought a brand new 500Gb WD external HDD a couple days ago and it will not mount but it shows up in disc utilities. When I go to disc utilities and try to format it for my mac I get an I/O error right away. So then I give it to my friend who also has a mac and he was able to format to HFS. I get it back and it still does not want to mount. Is there a problem with my mac or is it the HDD?

Software :: LaCie External HD Suddenly Not Mounting?

Jul 17, 2008

I have a new-ish Mac Mini and a MacBook Pro. I've been slowly migrating my Pro files to the Mini for some flexibility/stability. I've had the LaCie HD hooked up to the Pro FOR EVER. It's only ever been on a Mac--never a PC.

The LaCie seems to be fine.

However, on the Mini, it's suddenly mounting (both partitions--don't ask, I made them long ago and can't recall why) with a little lock at the bottom left of the icon. When I Get Info and look at permissions I have to unlock it and all/any users listed are noted with "Custom" preferences.

I can't R/W--I get "The folder "Stuff" could not be opened because you do not have sufficient access privileges.

About 90% of the time, SD cards and external hard drives are not mounting as soon as they're connected (via USB or the SD card slot). I need to launch disk utility, and mount volumes manually (disk utility is detecting the devices). This has persisted through multiple 10.7.X updates.

Hardware :: External Hard Drive - Exchange Keeps Mounting?

Aug 15, 2008

I recently got a new MBP as well as a 500GB Lacie External HD. I partitioned the external for 10GB windows and the rest Mac. Anyway whenever I plug it in, I get the external hd on my desktop as well as another icon called Exchange that has manuals and software for both OSs inside. I always just eject the exchange and keep the external HD mounted, but its annoying that it pops up each time I turn on the external. Is there a way to set my external up so that the exchange never mounts. What do I even use this for anyway?

OS X :: External Hard Drive Not Mounting After Improper Disconnection

Jul 4, 2009

I've had an WD My book 500 GB external for about as long as I've had my macbook about 1 1/2 years. No trouble with it at all, until yesterday. At some point either the power got cut or the cable was pulled out incorrectly it got disconnected from the mac. Thus resulting in it not mounting now. I've tried disk repair and shutting down the macbook and restarting...plugging in after everything is started. but to no avail. I am a photographer and about 25% of my photographs I don't have backed up anywhere else. So if I can't get it to work. I need some way to get the information off and reformat. or get it working correctly.

Hardware :: Looking For External RAID Device

May 5, 2010

My iMac is running out of room on the internal drive. I want to move my movies and pictures off to an external device. I am currently backing everything up using Time Machine (and Super Duper). What I would like to do is move them off but maintain redundancy in case of a drive failure (in other words mirror the external drives). I was at the Apple store today and the rep there suggested a Drobo device. It looks really cool. But, the problem is I saw a lot of negative feedback on it, including data loss which totally defeats the purpose of paying so much money for it. I'm looking for a way to basically have two 1 TB drives mirrored off of my iMac that I can put my iPhoto, iTunes and Movies onto.

I have a credit card terminal I want to use at a farmers market and it has a phone jack and an ethernet jack. If I have my laptop connected to my iphone via the hotspot (wifi), how can I get the terminal to see the laptop as a network? I assume if I just plug it into the the lapto via ethernet cabel, it will not see any connection for use, though I have not tried this yet. Is there some sort of interface or connecter that goes between the two so I can share my connection with another piece of hardware?

OS X :: External Audio Device With Internal Volume Control?

Sep 16, 2007

I have a slight problem with my volume controls on a Macbook Pro. They're not doing exactly what I want them to. I have an external sound card and by selecting it as my default audio device the macbook pros own volume control gets locked and there's no way to adjust it. This means that it renders the keyboard and Remote control volume buttons useless and I still have to run across the room to adjust the volume on my audio device when I'm watching a movie through the tv away from the macbook. Is there no way to enable this function anyway so both controls work?

OS X :: External Hard Drive Not Recognized - Unknown Device

Jan 31, 2010

Another one of those "external hard drive not recognized" problems: I am using a Mac Mini. The external LaCie drive is in one of those beautiful boxes designed by a guy named Porsche. It's connected via Fire Wire. I have my iPhoto library stored on it. It was working just fine for the past two days after I first connected it.

Now it does not show on the Desktop. It is identified only as "Unknown device" in "About This Mac." iPhoto doesn't recognize it. I've looked at the other threads on this subject here and have reset the PRAM. Disk Utility recognized it for a while and said the disk was OK. Now Disk Utility does not recognize it at all.

I turned off the drive and turned it back on. That resulted in an alarming series of beeps, almost like somebody was sending the Morse code symbol for "E" over and over again. I turned the drive off and then on again. Now the light goes on and the drive whirs nicely. I am using System 10.6.2. Or rather, at this point it is using me.

Hardware :: Won't Work With External Firewire Audio Device

Jun 25, 2009

Yesterday I took delivery of the following kit- http://www.dolphinmusic.co.uk/produc...firewire-.html

As you can see, it comes with the FCA202 Audio interface - http://www.dolphinmusic.co.uk/produc...io-fca202.html

I opted for the FireWire package as it has the most better quality mics. I got it all hooked up, but for some reason, my Mac is not recognising my new sound device at all. I was looking under the Sound part of the Control Panel, but nothing new would register. I checked the FireWire part of the Device Manager (appologies I forget the actual name of the application). The Firewire device was listed as "Unknown", if I was to remove the device and refresh, it would show nothing. So i've got the feeling that its been seen, just not recognised correctly.

I tried a few things to try and help my situation.

1) Disconnecting any other attached device
2) Rebooting several times
3) Leaving system off and unplugged for 10-15 mins
4) Updating all software
5) Resetting my xxxx (I forget the term, but it involved rebooting holding CMD, Option, R and P) - can someone confirm how I know if this was actually reset?
6) Going into Activity Manager and confirming the Audio driver is loaded

From what I've read, Firewire config issues can be common with Macs. I am running an 18 month olf iMac 20" with 4 gig ram. I've not used my FireWire port for a while, about 6 months ago I used a FW external HD which didn't have any problems with. Alas I don't have any other FW devices to plug in and test the port. The final thing I'm going for is to leave the system unplugged for 10 hours, which will be ready to check after work.

One thing I was thinking about though - would getting a powered FW hub be of use at all?

OS X V10.4 :: Starting From An External USB Storage Device (Intel-based Macs)?

May 31, 2012

I have a 2006 Intel Macbook with a crashed hard drive. I'm kinda broke right now, so instead of buying a new hard drive I loaded ubuntu 10.4 onto an external hard drive (USB) and tried to boot the macbook from it. (Failed). I hold down option to launch Startup Manager and all it shows me is a cursor (no drives). I know the external drive is bootable because I a) booted the laptop from a LiveCD and used it to create the hard drive and b) I booted a Dell from the external. I've tried moving the drive to a different USB port, but no chips. I don't have anything else connected to the computer. 

my question is: Can I boot the macbook from the external hard drive if the internal hard drive is shot?

MacBook, Mac OS X (10.4.11)

OS X :: Recover Data Fom Hard Drive / External Drive Stopped Mounting

Sep 4, 2009

So, I've been searching the forums, as I just had a 1TB (well actually a dual 500GB) external drive stop mounting and start clicking on me. I'm trying to find a way to recover files, and I know I've seen a lot of posts on DriveSavers, which. I was searching around, and I was wondering if anyone has ever heard of a company called "OneWorld Data Recovery." It was something I stumbled across, but I can't find any reviews, or nail down anybody who's used it.

Clearly, this seems fairly suspect, but I figured I'd check and see if anybody had ever heard of it or used it. Thanks!

I have tried dragging to trash, I have tried apple E (which is what I usually do to any device) and I have tried going into disk utility and ejecting/unmounting from there as well. no dice.
