External hard drive suddenly became "unreadable" and the disk utility offers not repair options. The drive is visible in disk utility but may not be mounted... any suggestions?

I have a WD My Passport 070A Media 2.0 TB external hard drive that has suddenly become unreadable on my laptop (MacBook Pro circa 2006 with 10.4.11) and I have tried on a MacBook Pro 2011 running 10.6.8 with the same results. I had tried opening disk utility to repair the drive, but on both machines the drive is visible in the left column, with no indentation below the drive. When I select the drive in the first aid portion the only options highlighted are info and eject... I was wondering if anyone had any suggestions to repair the drive. I am currently in Belize and am not home for 3 weeks yet. I'm hoping for a fix while I am down here, otherwise I may have to wait... I appreciate any assistance!

Hi Christina,
It's quite possible the AC PSU has given out, if It's only Bus powered as it appears, that's the worst idea ever & asking for eventual problems.
What Format is it?
Did you install any WD SW?

External Lacie drive suddenly became "unreadable by this computer"!!

Probably not the wisest thing to do, but I've just used a 160G Lacie drive to store ALL of the dv files and STP audio mix files for a 2hr project (and unfortunately one of the 3hr source clips), and the above message came up in red when I turned it back on.
If I look at 'about this mac' it is seeing the drive, but I get no options but to reformat!
I've tried it on 2 other iMacs, with the same result. The directory has obviously become corrupted somehow ..
Anyone know how I try and recover the files (which took me the best part of 2 weeks to create!!)?
Thanks,
Pete

Error: This disk needs to be repaired using the Recovery HD. When I boot on Recovery and run verify disk, the error doesn't come anymore. Just when I run verify disk on normal mode. Anybody has seen this before?

My Macbook Pro (Retina, 13-inch, Early 2013) has been freezing out of the blue probably once every two months. I restarted on safe mode, went to Disk Utility, repaired permissions and ran "Verify Disk" and got the following:
Invalid directory item count(It should be 114483 instead of 114484)
File system check exit code is 8.
Error: This disk needs to be repaired using the Recovery HD. Restart your computer, holding down the Command key and the R key until you see the Apple logo. When the OS X Utilities window appears, choose Disk Utility.
Rebooted on Recovery mode and ran "Verify Disk" but the message didn't appear anymore, thus not letting me to access the "Recovery HD" procedure.
When I restart normally and do the disk verification I get the same error.
Has anybody come to something similar?
Suggestions?

I never ever run a Verify Disk. I simple repair the disk drive and then the user partition(s).
And do one or two Safe Boots.
Also helpful to have two full backups: TimeMachine at least, plus a clone of your system drive and data.
Install or clone the system to an external hard drive, repair that and then boot from it, check that everything works, repair the internal drive.
You need to use Repair to TRIM an SSD.
Lots of problems with Yosemite when updating install a new OS. Always better to backup, erase, install, and then use Setup Assistant to import and restore settings and files.
Probably better to post in the MacBook Pro forum or better yet, in Yosemite forum.

I have HDMI connection to the receiver and on to the TV - but no audio from my new Apple TV. I have checked all connections and the video is xlnt. Have also toggled thru every possible Dolby/Audio combination in settings. Help! Any suggestions?

I have an HDMI connection to the receiver and on to the TV - but there is non audio from my Apple TV. Not for movies, music, YouTube etc.   I have checked all of the connections and the video is xlnt. Have also toggled thru all possible Dolby/Audio combinations in settings. Help! Any suggestions?

Hello again Parker -
The basic setup is Digital Cable Box, DVD Player, Denon Receiver/Amp and TV Monitor. To that I added the Apple TV. The Receiver only has two HDMI IN slots (one for cable and one for the DVD) and one out to the Monitor.
[I bought a switcher to toggle the DVD and the AppleTV back and forth but just disconnected the DVD to simplify when I ran in to trouble.]
So now I have:
     HDMI from the Cable Box to the Receiver
     HDMI from the Apple TV to the Receiver (in the old DVD slot which always worked well)
     HDMI from the Receiver to the Monitor
     RCA's from the Receiver to the Subwoofer and the other speakers
In addition I have some backup connections:
     S-Video, Optical Audio and L/R RCA's from the Cable Box to the Receiver
     S-Video from the Receiver to the Monitor
Wait - JUST FOUND IT!
By going thru the excercise to track all of the connections per your suggestion, I found an anomaly when I switched Receiver sockets for the HDMI links. The video moved but the audio didn't. Turns out the monitor was using the optical audio feed from the receiver. So I disconnected the optical audio and the monitor automatically switched to the HDMI audio feed!   Looked promising...
So I first connected an optical audio feed from the ATV to the receiver - Audio! Then I pulled it, but the audio didn't switch to the HDMI feed. It stopped. Would be OK if all I was going to use is the ATV, but I need the DVD player too and I can't use a switcher to toggle between them if I have to unplug the optical audio each time.
This is becoming a career! Any suggestions?

Have you performed a reset? Tap and hold the Home button and the On/Off button for approximately 10-15 seconds, until the Apple logo appears. Release both buttons and await restart.

I upgraded my 3 yr old iMac to Snow Leopard and now my HP C4150 Scanning function doesn't work (not recognized). I downloaded updated Drivers from the HP site, but still no joy. Any suggestions?

aspaceman,
Perhaps I owe you an apology. Having re-read that downloading from HP was unsuccessful I feel uncomfortable. Can I suggest you update your 10.6 system (as noted in your profile) to 10.6.8 (if it is not already there) by using the
Mac OS X 10.6.8 Update Combo v1.1 combo update plus any software updates that then apply.

TS4009 I have followed the steps above but when I get to the screen to select a downgraded option, the Done button is grayed out and won't let me select a new option. I see a lock up in top right-hand corner, but not sure how to unlock it.

I have followed the steps above for downgrading iCloud storage options, but when I get to the screen to select a downgraded option, the Done button is grayed out and won't let me select a new option. I see a lock in top right-hand corner, but not sure where to go to unlock it.

Choose Apple () menu > System Preferences, then click the iCloud icon.
Click the Manage button.
Click Change Storage Plan.
Click Downgrade Options.
Enter your Apple ID password, then click Manage.
Choose your current plan, then click Done.

It does seem rather odd that an app that was acquired thru itunes would quit working once it was incorporated into the device for all users. oh well it was probably free or $.99 when I downloaded it.
I would think that they were just testing it to see how many people would use it. But you might want to write a polite letter to Apple requesting a credit for the purchase price of the no longer supported app. That seems to be the least they could for one of their 'alpha testers'.

My iphone4's battery went dead and when I put it on charge it asked for itunes. I dont have my macbook at the moment and I am worried I may loose content. Any suggestions how I can get into my phone?

Copy the iTunes folder from the disk to the Mac, and the iPhone backup to the right place on the Mac (Google for "iphone backup location"). Then when you restore you can reload the last backup.

Suddenly I can't find the volume bar on iPod nor YouTube apps. Also I can't hear anything from both apps. Any suggestions? I have an iphone 3gs

Have you taken the steps recommended in the User Guide--restart, reset, restore from backup, restore as new?
What happened after taking each of those steps?

I bought a mini DVI to HDMI convertor and a HDMI to VGA cable to connect my mac book pro to a tv but it doesn't work any one can help.\\\\\

i bought a mini DVI to HDMI convertor and a HDMI to VGA cable to connect my mac book pro to a tv but it doesn't work any one can help.

I would suggest looking into a Thunderbolt to HDMI connector. In this case, you may be able to use the TV as an external monitor. For this option, please confirm through additional research. I have not tested it personally.
You can also use an Apple TV, which connects with HDMI. In this case, you can use Airplay Mirroring. Not all Macs support Airplay Mirroring, so you need to check first. I have a Mid-2011 27" iMac, and it supports Airplay Mirroring. I don't use it often because my TV is in another room, but I just tried it and it worked. It had to change the screen resolution to work well, so I don't know if I would want to use it as my day to day monitor. http://support.apple.com/kb/ht5404
