External FW HD not read

Running G4 450 mhz tower with OS X server 10.2.8 (6R73)
Had external FW drive set up and partitioned as (for purposes of discussion) drives C and D
Students accessed their password –protected folders on drive C via network
Over break I shut the server down, disconnected the external drive and took it home to check their work.
Accessed files without need of password from MacBook Pro running OS 10.4.11
Upon return from break External driver will not mount on server – no icon, nada.
Disk First Aid does list the volumes but they are grayed out. Workgroup manager lists sharepoint but has no icon in front of it and Server error message is “selected share point can not be found. One or more items in /Volumes/ C may have been moved , renamed or deleted”
How do I get the external drive to mount back to the server?

This question was not answered.

Is the external USB drive product an Apple USB SuperDrive?
http://www.ifixit.com/Device/Apple_USB_SuperDrive
Not sure if a cleaner disc would help, or if there is a defect in the
drive which may cause a disc to be re/jected. If the drive were an
internal one, a reset may apply; such as NVRAM. However due
to this being an external one, I don't know if that'd do anything.
You may have to look on the maker's site to see if there are any
support links or suggestions on how to make it work, if not Apple.
There are some Support articles concerning their USB Superdrive.

•Intel-based Macs: Resetting the System Management Controller (SMC)

Could be this reset may help the optical drive work correctly.
But your mileage may vary, depending on other circumstance.
Good luck & happy computing!

External Hard drive not reading after 10.3.9 update

Hi there and thank you for this forum. I am wondering if anyone can help me through this maze of confusion...I have just recently upgraded from 10.3.5 to 10.3.9 and now I cannot access my external Fantom Drive. Both of the USB ports can read other devices, and also I can still read the Fantom from a PC, but when I plug it into my ibook, I get nothing.
Can anyone recommend anything? Can I reinstall the original 10.3.5 software and be done with updates? The Fantom is not supposed to be affected by the 10.3.9 system, so I don't know what happened, but I can tell you that the only 2 times I have updated this mac, I have had serious problems! I won't be updating anymore!!!
Thanks mates...

You're welcome.....and thanks for acknowledging me in your post....
I'm sure you would have thought of this workaround sooner or later....After 2 reinstalls of OSX this was my last resort.

External Optical drive not reading? Or is it my programs...

Hi,
I currently just got a macbook pro 2011, 15". Two internal drives (120 GB SSD for OS and Programs, 750 GB HDD for Data) & external USB Optical DVD/RW
The issue I'm having is when I insert a real DVD into the external optical drive (which is the orignal from the macbook pro not store bought) it doesmn't read the DVD. I have installed Quicktime, VLC player and everytime the external just gives me the VIDEO AND AUDIO TS folders.. any suggestions in what I need to do so I can play DVD's from my external?
Thanks a lot...

DVD Player requires a properly recognized DVD player to be present in the optical bay in order to play DVDs. You can use VLC, but you will have to do as you're doing. Another option is to edit the DVD playback framework, but I'm not going to post those instructions. You can use Google & do so at your own risk.

I converted from a PC to a Mac Mini. I have my PC documents backed up on a DVD disk. I have an external DVD drive connected to the Mac Mini. I want to open them up and save them to the Mac, BUT....when I put the DVD disk in the Mac is NOT reading it!

Hi Joe,
Thanks for your quick response. I should add....it worked before. When I previously inserted the two DVDs into this remote drive, and I went into finder, I could click on the "remote device" line and see all my saved documents (excel, word, etc) on the DVD and open them on the Mac. Now I cannot see them, when I try to open them on the Mac, nothing happens, nothing is displayed. I just re-tested the remote DVD drive with a CD and, no problem, it opened up the CD via iTunes and I cold play the CD. SO......I know the remote DVD drive (it's an LG by the way) is fine, it's something to do with some settings on my mini mac,especially where I could open it previously. I do not remember changing any settings since then.
When I go into system preferences and click on CD/DVD it gives me options of how to open up a music CD (default is iTunes), a DVD (default is iMovie), etc. The problem is my DVD is all miscellaneious files/documents. I just want to be able to see them in the finder. I also tried to open them via microsoft word, from the remote disk and again, it could not open the drive, even though some of the documents were microsoft word documents. Again, I was able to open them previously and the DVD is not corrupted in any way.
Any additional advice?
Thank you!

My external Iomega DVD drive does not read DVDs. Why?

My external Iomega DVD drive does not read DVDs. Why?

what does this question have to do with a mac? post in the Iomega fourms.

New external hard drive froze while transferring info to new computer. Laptop does not read external hard drive. Went to Apple store and didn't work. Any suggestions?

Day 1. Went to Apple store because iMovie was not working. It kept shutting down. Prior to going to the store, I called Apple Support and deleted and reinstalled iMovie. Still did not work. Then I went to the Apple Store. After an hour it finally worked but when I got home, it didn't work AND my iPhoto application was missing. Tried to back up on external hard drive but it didnt work.
Day 2. Explained the situation again to Apple employee at Apple Store. I bought an external hard drive that employee recommended and picked out. I went home and backed up my computer on the external HD.
Day 3 (morning). Went back to Apple. Employee verified that my hard drive was backed up successfully. All my photos, music, and documents were successfully backed up. He was going to reinstall the operating system. He did that successfully. He showed me how to install the external HD info to the laptop. I went home and followed the directions. It was going to take about 2 hours. I kept monitoring the progress and everything looked good until....30 minutes remained. 30 minutes remained for a good 20 minutes. The ext hard drive stopped responding. I tried to canel but there were no buttons to push. I exited the program. I called apple support and they tried to walk me through it. My computer still was not recognizing that the exteranl HD was plugged in. I mad another trip to the Apple store and the emplyee confirmed that the extranal HD was not reading. He tried plugging it in to his computer and it still wasnt reading.
He did give me a data recovery number to call. I asked if Apple would cover the cost and he said no. I called then and was quoted $700-$2000 to recover the data.
Does anyone have any suggestions? When frustrates me more is that I followed every instruction and I did exactly what Apple told me to do. Now, ALL of my data is lost and Apple does not want to help.
Does anyone have any suggestions on what to do next? I need help. =*(

Hi rkaufmann--
Thanks for the response. I can say with confidence that that is not the issue. I have at least 8 of these same WD external portable drives that are powered through their USB 3.0 cables, and I have never had problems with any of them. Sometimes I connect them directly to my computer, and sometimes I use a powered hub. Either way they work fine. The drives with their own power source do not suit my needs.
My question is specifically whether anyone has seen an issue where sometimes they plug a drive in and it is not recognized but then it continues to work. In other words, the question I'm posing to other users is whether it sometimes happens that they connect a drive and it simply doesn't show up, but then they disconnect and reconnect and it goes on working fine as it should.

Final cut pro X not reading events in external hard drive

I know this has been talked about in one way or another but I still am just not understanding. Any help I can recieve will be much appriciated. Just purchased Final cut pro x and I have an external hard drive that I have some events on. FCPX will recognize the external hard drive but says there are no events in the external hard drive. I checked 2 other external hard drives as well and all three FCPX will not read the events that are in the hard drive.
Thanks
Brian

Brian, I notice that I have to have whatever drives connected before openeing FCPX; so sometimes when you plug in a USB3 drive or a Thunderbolt drive on the fly, even if though it mounts, it won't be recognized until you re-launch FCPX.
Beyond that, it's important to make certain that you name the two folders in the attached drive exactly: Final Cut Events, and Final Cut Projects, and they should be on the root directory of the connected drive(s). On all of my systems, if you have multiple drives connected with identical projects, FCPX actually picks one and warns you that there are two different identical projects and tells you which one it opened.
If you take the time to provide Tom with what he's asked, he is extremely helpful and will likely identify the issue.

Right USB Port not reading External HD

I'm using Mid 2014, Retina, 13-inch, Macbook Pro. I noticed that my right USB Port is not reading my 1 TB WD External HD but able to use mouse. How to fix it?

According to the fount of knowledge that is Wikipedia…
https://en.wikipedia.org/wiki/USB
As with previous USB versions, USB 3.0 ports come in low-power and high-power variants, providing 150 mA and 900 mA respectively, while simultaneously transmitting data at SuperSpeed rates.[25] Additionally, there is a Battery Charging Specification (Version 1.2 – December 2010), which increases the power handling capability to 1.5 A but does not allow concurrent data transmission.
It doesn't make sense to me that a 'low power' USB port would output 500ma unless it was working in USB2 mode.
A unit load is defined as 100 mA in USB 1.x and 2.0, and 150 mA in USB 3.0. A device may draw a maximum of five unit loads (500 mA) from a port in USB 1.x and 2.0, or six unit loads (900 mA) in USB 3.0.
You may want to get the genius to confirm the spec for both ports if you go along to a store, I guess they may have limitations.
I would also boot into recovery mode just to see if the disk pops up in Disk Utility via both ports - that could indicate the port is being rendered useless by the OS.
Apologies, you appear to have tried that already.

I have an imac 2009 the disk drive is damaged and I have lost the passwords I need to reset passwords I tried booting with a macosx disk from an external hard drive but did not read the drive how else can I reset password ?

I have an imac 2009 the disk drive is damaged and I have lost the passwords I need to reset passwords I tried booting with a macosx disk from an external hard drive but did not read the drive how else can I reset password ?
I have a 2012 mac book pro can I use that to connect with firewire and load osx that way? and how woudl I do that?
Thanks so much!

To what password are you referring? Do you mean your user account's admin password? Or do you mean the master password for File Vault or do you mean a Firmware Password?
For an admin password:
Forgot Your Account Password
For Snow Leopard and earlier
     Mac OS X 10.6- If you forget your administrator password
For Lion/Mountain Lion
    Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
     When the menubar appears select Terminal from the Utilities menu.
     Enter resetpassword at the prompt and press RETURN. Follow
     instructions in the dialog window that will appear.
     Or see Reset a Mac OS X 10.7 Lion Password and
     OS X Lion- Apple ID can be used to reset your user account password.
If you cannot do the above then try this:
1. Boot to Safe Mode by restarting and after the chime press and hold down the COMMAND-S keys until a black screen with white type appears.
2. At the prompt, type the following commands pressing return after each command line:
     /sbin/fsck -yf
     If you do not receive a "Filesystem OK" message then repeat this command until
     you do. If after seven tries you still do not receive a "Filesystem OK" message,
     then the system is corrupted and needs to be reinstalled.
     mount -uw /
     cd /private/var/db/netinfo
     mv local.nidb local.old
     rm ../.AppleSetupDone
     shutdown -r now
The second-to-last command above will cause OS X to think that the operating system is newly installed, and when the new owner starts up the computer it will send him/her to the startup wizard where he/she can start a new user without reinstalling.
This last method does not actually change a password. It simply removes the user accounts and lets you create an initial admin account as if the computer were new out of the box.
How to reset the OS X password without a startup CD:
Reboot into Single-user Mode. Enter the following and press RETURN after each command line
   1. Type fsck -fy
   2. Type mount -uw /
   3. Type passwd <username>
I have never tried this method myself.

MBP Not Reading HSF+ External HDD/Bootcamp Win7 Is ?!?!

Hi - this is a strange one to me. After creating separate partitions (NTFS/FAT32/HFS) for my LaCie Ext-HDD, I been able to shuffle data between my Mac and PC computers (teach in a lab). However, one day - for no specific reason - all drives except FAT32 would not read. But what's more odd is that the HFS is readable only in Win7. What's more strange is that the NTFS drive is not, and is only readable in OS X (via some 3rd party software).
Has anyone experienced an HFS HDD that's not readable in OS X (Snow Leopard)?
Any advice on how to retrieve my data in OS X (the BC-Win7 is not large enough to support the data transfer) ?
Thanks so much in advance!
ACV

I have a similar problem... tried to install winXP on an external HDD (read in FAQ after there you are not suppose to ><)
anyway after I installed XP my mac cant find any bootable partitions (had OSX 10.6.3 and Win7 working perfectly)
the wierd thing is when I boot off the intallation CD I can only see the Win7 partition and it says its empty.. even after I removed the HDD from my mac and hooked it up as an external HDD to my mac desktop the Win7 partition came up empty aswell but the mac partition was nowhere to be found...
I really need my data back from my Mac partition I dont really care about what was on the Win7... please someone tell me there is a way!!

EMac External LACIE DVD Drive not reading.

eMac External LACIE DVD Drive not reading.
eMac 700 MHz running OS X 4.4
Came without DVD or modem internal
Has 256mb memory
Bought a used Lacie 1394 Firewire DVR External.
Was able to burn DVD’s and CD’s with Toast 6 Light.
Cannot find the “DVD Player” on the hard drive.
It will read data DVD.
eMac will not read any movies burnt or bought.
I was told I probably need more memory?
Thought running IDVD would fix the problem.
No Soap.
This machine was giving external modem problems before Tiger was installed.
Before we spend more money or just get ride of the eMac.
What is the DVD problem?
This same Lacie burner reads and writes DVD and CD fine with our iMac 450 DV 320mb memory. Running 9.2 and X.3

OS X 10.3.x / 10.4.x natively support data burning to external DVD drives but video payback requires software such as iDVD which isn't installed by default on models without an internal DVD drive (the installer sees no internal drive and thinks it's unnecessary). Try downloading VLC Player and see if that will let you play movies.

Mac OS X Lion 10.7.5fter upgrde does not read external harddrive

Mac OS X Lion 10.7.5 fter upgrde does not read external harddrive

Hello there ZamirasDAD,
I was looking through our aricles about what you may be experiencing and recommend resetting your SMC and your PRAM.
To reset your SMC on an iMac you would use this article Intel-based Macs: Resetting the System Management Controller (SMC) found here: http://support.apple.com/kb/ht3964.
Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
To reset the PRAM use this article named About NVRAM and PRAM found here: http://support.apple.com/kb/ht1379
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
Regards,
Sterling
