I upgraded to Mavericks, now I cannot use my External Hard Drive

I have a 13in 2009 MacbookPro that I recently upgraded to Mavericks, and since the upgrade I am unable to mount my Toshiba External Hard Drive that prior to the upgrade worked wonderfully with this computer. The HD still works with my Windows PC. I have run Disk Utility and it appears but is greyed out and says it needs to be repaired if I try to mount it, but repairing has done nothing to help.
I need to get my HD working with my MacbookPro again. Please help me.

Welcome to Apple Support Communities. We're users here and don't speak for "Apple Inc."
Since you say you are using your drive with a Windows PC also, were you using a program such as NTFS for OS X that now needs to be upgraded to work with OS X 10.9 Mavericks?

Can I use one external hard drive for 3 of my Macs?

I have a 2007 white MacBook, a 2011 MacBook Pro, and a 2013 MacBook Air.
I want to be able to transfer all of my precious family photos off of my MacBook and Macbook Pro onto an external hard drive and then wipe those computers clean, and then I want to be able to backup and wipe clean my Macbook Air so that I can update it to Mavericks.
Can I use one external hard drive to do this for three of my Macs? Will it be compatible with all of them? And will I still be able to use the hard drive with my Air once it is updated to Mavericks?
Which hard drive do you recommend?

1. Yes. Note that anything you want to keep should be on at least two drives in case one of them fails.
2. Yes.
3. Yes.

Upgrading to Mavericks wrecked my MacBook Pro & now it only works when external hard drive is plugged in

So I tried to upgrade to Mavericks today and it failed (same error as in this post which seemed to be a common problem). It wouldn't let me repair the disk, and after trying all sorts I rebooted my computer in recovery mode - it wouldn't let me reinstall Lion because the hard drive was apparently locked and I could see no way around this. So I decided to restore from a Time Machine backup on an external hard drive and that worked okay, except my MacBook now only works when the external hard drive is connected. If I remove the external hard drive, I'm back to square one as it still won't let me reinstall Lion as the HD is locked!
I have no idea what's going on. HELP!

The startup drive is failing, or there is some other internal hardware fault.
Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Keeping your confidential data secure during hardware repair
Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.
*An SSD doesn't need to be zeroed.

Do you get this window when you hold down the Command+Option keys and launch iPhoto?
If not then you're not holding down both keys long enough.

I cannot connect my external hard drives (1 WD My Passport and 1 LaCie Porsche Design). The drives were connected and worked perfect, the WD is used as a Time Capsule, the LaCie is formatted as exFAT and used for miscellaneous. They are both USB 3.0

I cannot connect my external hard drives any longer. I have one WD "My Passport" used as a Time Capsule and one LaCie Porsche Design used for all different kind of data, formatted in exFAT. They worked fine, connected direct or through an additional USB hub or also attached to a Dell monitor. The Lacie helds my iTunes Library and the iPhoto library.
After I moved the iTunes library to the external drive, from time to time the drive went into a never ending loop and I had to shut down the laptop (MacBook Air).
The last time starting again the drives were not recognized any longer. I tried to connect them to another MacBook, which didn't work.
Starting with Windows 7, the WD is also not recognized at all (perhaps because of time capsule format?) and the LaCie gives an error.
Could anybody tell me if there is a chance to get them alive again? When I connect them now, they start to heat up quite fast without anything else happening.
Thanks

Hi,
Just want to clarify, have you checked to make sure the cords are not damaged (going from hard drive to computer and or any power source )?
You have also check to make sure that usb ports are working correctly?
If you have checked these things it may be that the external drives have failed.
I would google the error message from the LaCie drive before I do anything.
There are several ways that I know of, one is to put the hard drive in the freezer for a while (make sure you wrap it air tight) if this works it is not a permenint fix. You might be able to transfer information to another source.
The other method is to plug the hard drive into a hard drive connector a product like this:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817707192
to do this you would have to remove the hard drive from its enclosure and still this is not a guarantee it will work.
The finally way I know is using a recovery service. This can be rather expensive, and there are no guarantees

I have 1 gb of memory with10.6.8 and want to upgrade my OS can i use an external hard drive to solve this

I am running 10.6.8 and have 1gb of memory and want to upgrade can i use an external hard drive to solve this problem

You are confusing RAM (Ramdom Access Memory) with hard drive storage space.
You need to install more RAM, not an additonal hard drive.
You can purchase an external hard drive, if you like, if you want to install the new OS X upgrade onto an external drive. If you want to run the new OS X Mavericks from the external drive, depending on your Mac model, you need a fast protocol external hard drive.
Either a USB 3.0, Thunderbolt or FireWire 800 connected external hard drive.
To start, if you are running your Mac on 10.6.8 Snow Leopard, this is the barest of RAM to run Snow Leopard.
Without knowing any of your Macs specs, you realistically should be running your current OS with, at least 4 GBs of RAM.
Newer versions of OS X need, at least, 4 GBs of RAM or more as these newer OS X versions use more Mac computer resources than earlier OS X versions.
What year, screen size, CPU speed and amount of RAM installed in your Mac?
Be aware, if your Mac is running any older software that used to run under older PowerPC model Macs, those software apps will no longer will work under newer versions of OS X.
The emulation software that allows older PowerPC apps to run under OS X 10.6 Snow Leopard, called, Rosetta, no longer exists in newer versions of OS X and is long dead.
Correct and reliable Mac RAM can be purchased from online Mac RAM sources Crucial memory or OWC (macsales.com).
Good Luck!

How do you remove back up data from the memory storage? my storage data states that i have over 80gb of data used for back ups and i dont know why as i use a external hard drive as a time machine .now my 250gb flash storage is nearly full

When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
See this support article for some simple ways to free up storage space.

Since I downloaded Maverick, I cannot find my External Hard Drive in the "Finder" area. I have to unplug all the time the hard drive to be recognized by my iMac. How can I fix this problem? Thank You.

Check Finderr->Preferences->General and ensure that HDs are selected for display. If so and they still don't, Reset the NVRAM/PRAM and Reset the SMC, and see if that does the trick.

I have bought a time capsule to use as time machine device. Until now I have used a external hard disk. How can I transfer the the old time machine datas to the time capsule?

This is really difficult to the point of not really worth it.
Keep the old TM backups in archive.. and start afresh on the TC.
Time Machine has a different way of backing up on Network drives cf Local drives.
Pondini does have a method to do it... but I would not recommend it.

I have been using an external hard drive on a PC, I have now moved over to a macbookpro, is there a way to reformat the hard drive without deleting the files currently on the hard drive?

if it's fat32 then the mac can read it without problems
if it's ntfs then you can install programs which make it possible to write to it too otherwise it's read only

Using an external hard drive with Airport Extreme

I'd like to use an external hard drive to store movies and music through my Airport Extreme. The drive is connected to a powered usb hub which is connected to the Extreme. I can see the drive in Airport Utility but I can't figure out how to use it.

Hi,
I have just tried to set up an Airport Extreme with an external hard drive at home. I have 4 computers connected to the "network" - an iMac, a MacBookPro and 2 x windows machines. A printer is connected wirelessly to the two Macs.
I cannot find the hard drive - I have tried the steps mentioned by Bob Timmons Mar 17 2010, but the only things I see under "Shared" in Finder are the iMac and the printer - not the Airport Extreme (seems odd??), not the windows machines, and most importantly, not the hard drive connected to the USB port on the Airport Extreme.
I therefore expect that the iMac and printer are connected wirelessly and directly, rather than through my network (& I'm happy for the printer to be connected this way, but I do need the PCs and the hard drive all networked).
According to my network connection, (in top bar on the screen) I am definitely connected to the network - yet nothing else shows in finder??
I do, however, see the USB hard Drive when I go into Finder>Applications>Utilities>AirportUtility.app, under my Airport Extreme >Disks. I've also gone through all the set up procedures for "File Sharing."
I have read other posts about formatting the hard drive ether FAT32 or NFTS - is this something I now need to do?? If so, which one should I use, and once I do it, will I then see it?
Presumably, in order to format the Hard Drive, I will need to disconnect it from the Airport Extreme, and connect it directly to one of the Macs too?
My apologies for so many questions, but this is all very technical stuff for the non-techie layperson.
Many thanks for any help anyone can provide on one or more of the questions / issues.

Hello, i am new to the mac and i need to learn how to re image using an external hard drive

Hello, i am new, like baby fresh new,...lol, to the mac and i need to learn how to re-image using an external hard drive.

How to replace or upgrade a drive in a laptop
Step One: Repair the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Step Two: Remove the old drive and install the new drive. Place the old drive in an external USB enclosure. You can buy one at OWC who is also a good vendor for drives.
Step Three: Boot from the external drive. Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears. Select the icon for the external drive then click on the downward pointing arrow button.
Step Four: New Hard Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your new hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Step Five: Clone the old drive to the new drive
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Check the box labeled Erase destination.
5. Select the destination volume from the left side list and drag it to the Destination entry field.
6. Select the source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the new internal drive. Source means the old external drive.
Step Six: Open the Startup Disk preferences and select the new internal volume. Click on the Restart button. You should boot from the new drive. Eject the external drive and disconnect it from the computer.

Restoring using an external hard drive help

Ok so.. ive recnelty received my mac back from apple, after javing the hd replaced. To prevent the loss of all of my stuff i bought an external hd and used this as my time machine backup, so now its all on my external hard drive. The problem ive got is that ive got no idea how to restore my mac using the extermal hard drive so its like it was before it was sent off. ive been told one option is to launch my mac in recovery mode and choose to restore using. my external hard drive there. however i cant access recovery mode because i have a wireless keyboard, and the only wired keyboard i have is a windows one. also, to make matters worse, i cant use any discs because my optical drive is broken, so until i receive my extermal one, discs are also out. of the option.
any other ways to do it?
thanks!

Try this, your going to be using a program called Migration Assistant to restore data from a different computer's Time Machine. Your computer is a different computer now because of the new Hard Drive, so instead of entirely recovering the Operating System, this will save time and data by allowing you to choose individually what you want to restore and what you don't want to.
Do not use Migration Assistant, instead you will use Setup Assistant (which starts automatically when you first start your Mac) if you already started you Mac and added a user then you will have to use MA, but you will need to remove a user afterwards.

How do I transfer my data to my new macbook pro using an external hard drive?

I've already set up my new MacBook Pro is my issue. It asked me if I'd like to "Migrate" my stuff or use an external hard drive etc but at the time I didn't transfer my data from my old MacBook yet. I was going to manually do it later as I had to wait for my External hard drive to back my old Mac up. Now it's that time and I have no idea how to do it. I believe I've researched best of my ability.
I feel like I'm asking a pretty dumb question. If I were to just drag all my programs out like my Adobe Suite on to my new macbook pro would that work? I feel like that's just too easy and incorrect. Please and thank you.

The Adobe suite can be downloaded free, you dont have to copy it at all, under standard CS6 Adobe rules, if you own the suite, you get 2 computers "activated at any one time" Make sure, if youre not using the older computer, you deactivate the software under the HELP menu in Adobe.
format the new drive in disk utility ......APPLICATIONS.....UTILITIES.....DISK UTILITIES.......select the external drive and format (if its new and empty!!!) under the ERASE button with Mac OSX extended journaled
copy all your important stuff from older computer , pics, files, documents, personal anything.
most of you apps, i ASSUME you bought in the (other than Adobe software, or Office suite, etc etc,..... obviously) in the MAC APP store, so you can reload them on the new computer without copying them , makes things very easy......just open APP STORE, and download what you already bought.
really the only important things , is copy all important work files, documents, pictures, personal ABC...XYZ...... obviously.
the migration is about emails, contacts, etc etc etc, also data, just because you passed it by at the time doesnt mean you still cant do it, go to the SEARCH at menu at top and type in MIGRATION ASSISTANT to do it again , since you passed it by at first .
the only thing you NEED / SHOULD copy is all your personal stuff........Applications need to be reinstall from either ONLINE download,.......or from the MAC APP STORE,........ you cant just copy the apps over (in most cases) and toss them onto the new computer
Nahh, there are no dumb questions, just dumb mistakes because you DIDNT ask any questions, and we all make those here and there.

I upgraded to Mavericks, now I cannot use my External Hard Drive
