I have a 1TB external hard drive (NTFS) that has all my files from my old PC, how do I create a partition on it for HFS without formatting it so that I can use it for Time Machine and the like?

There aren't any 3rd party apps or anything. I use PC's and Mac's at school and the only computer connected to a printer at my house is a PC so i need access to both

HELP !! My external hard drive is corrupted with all my files !!!!!

So my Seagate Hard drive has been working fine for 1 year, and now when i plugged it in it does not show up on the desktop !
I go into Disk Utility, on the sidebar, instead of the name I set, my disk is now called "disk2s1". I tried to verify it, and it says:
Verifying volume “disk2s1”
Checking file system** /dev/disk2s1
** Phase 1 - Preparing FAT
** Phase 2 - Checking Directories
Unable to read directory (Input/output error)
Error: This disk needs to be repaired. Click Repair Disk.
So i tried to repair it

Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
Please please help me ! I dont want to lose all my movies that I havent even watched. I can buy a brandnew hard drive to copy all my files in but the folder dont even show up on the desktop ! I tried to "mount" it but it doesnt work neither.

Some say "Disk Warrior" can recover corrupted file systems. The cost ($70, I think) and extreme measures it uses makes it a "last ditch" tool instead of a "regular miantenance" tool.

I currently have a MAC Mini, which has 1 Firewire 800 port. I have a 1TB external hard disk that runs at Firewire 400. Can I insert another external hard drive that runs at Firewire 800?

Here's the deal. Currently running SL 10.6.8 on a MAC Mini. Planning for eventual upgrade to ML. Have a 1TB external hard drive partitioned into two volumes, one volume for Time Machine and one volume for SL which I periodically update using Superduper. Thus I always have a point-in-time bootable backup on the external hard drive.
The MAC Mini supports Firewire 800. However, booting from my current external hard disk is pretty slow, since it only supports Firewire 400. I am considering buying an Iomega MiniMax which supports Firewire 800. Then, I would use the MiniMax as my bootable backup volume, and relegate the older hard drive to Time Machine.
So, question #1 is, can I daisychain the new MiniMax between the MAC Mini and my existing external hard drive? My expectation is that the new Mini Max would run using Firewire 800 and that the existing hard drive would run at Firewire 400 speed as it does today. If it doesn't (e.g., daisychaining in the Firewire 400 external disk with the MiniMax Firewire 800 external disk ends up running the whole leg at 400), my resolution will be to run the existing hard disk off an available USB port and have just the MiniMax running at Firewire 800.
Why am I going to all this trouble? That's question #2. I don't trust upgrades; they always break something. When I upgraded from 10.5.x to 10.6.x, the web directories got renamed, and all of my web apps 403'd until I figured out what happened. Plus, I have accounts for other family members, and in order to ensure their ability to use the computer during my upgrade process, I need to have the ability to fall-back quickly to a known-stable version of OSX. So what I'm trying to do is insulate myself from problems by partitioning the MiniMax into two volumes, taking a Superduper image of my current installation on the Mac Mini to MiniMax external drive volume 1, then upgrading to ML on the MAC Mini, and take a SuperDuper image of that to MiniMax external drive volume 2. Then, if the upgrade results in problems I can't resolve immediately, I can simply reimage the MAC Mini from MiniMax volume 1. BUT ...
... I've read that the ML installation creates a "service and support" partition that is different than the startup disk. I'm concerned that I won't be able to reimage the hard disk in the MAC Mini once I upgrade it to ML because of the partitioning changes it introduces on the startup disk. Theoretically, I +should+ be able to use the disk utility on my SL system to repartition the disk in the MAC Mini prior to reimaging it from my backup, but I'm considering the possibility that the new partition may be of a type that the SL disk utility cannot identify, and might therefore be unable to delete or even detect. So I'm hoping someone else has been down this road and can advise me. Even at Firewire 800 speeds, booting from an external disk is still going to be slow, so I want to be able to restore my SL image to the MAC Mini hard disk.
A little background on me. I work for a major disaster recovery provider. I used to have a Mac PRO G5, which I got used, and the first thing I did with it was install a second hard disk, SuperDupe an image from the first disk to the second, and made sure I could boot from the second. THEN I started using and customizing the MAC. I really feel vulnerable with the MAC Mini, since it only has the single internal hard drive - sort of like going out in public dressed only in a long T-shirt. So my whole thing is, I ABSOLUTELY MUST BE ABLE TO PUT THINGS BACK THE WAY THEY WERE before I do the migration to ML.
Obsessive-cumpulsive? Yep. Anal? You got it. That's why I'm in the DR business.

You may have overloaded the port, following the instructions below it should reset:
+1. Shut down the computer.+
+2. Disconnect all devices and all other cables, except the keyboard and mouse cable(s).+
+3. Disconnect the computer from the power outlet and wait for 3 to 5 minutes.+
+4. Plug the computer back in and turn it on.+
+5. Reconnect the device(s) (one at a time if there is more than one) and test. Test with each port if you have more than one.+

Help needed. I have a 3TB external hard drive partitioned into 1TB's. I used one partition as backup for the main computer hard drive. But now it is greyed out as shown in the disk utility and its name changed, i dont know how that happened, i tried verifying and repairing it but had no luck. I also tried mounting and unmounting it but still no solution. Anyone to help please?

Looks bad. I would strongly advise backing up the stuff on the other two partitions as soon as possible in case the rest of the drive goes wrong.
Beyond that, Disk Utility has limited abilities to repair disks, DiskWarrior uses a different approach and might, emphasis might be more successful. It has certainly done the job for me in the past when Disk Utility could not.

This article has a link for more information on finding your profile directory: [[Fix the "Could not initialize the application's security component" error message]]. On Windows 7, you can try this (either in a Windows Explorer window address bar or from the start menu search box):
%APPDATA%\Mozilla\Firefox\Profiles
You may see one folder in there and that's the one you want. If you see more than one, look for the one with the most recently modified files.

I cannot find this 300GB "Backup" in the Finder, only in the Storage info when I check "About This Mac".
You are probably using Time Machine to backup your MacBook Pro, right? Then the additional 300 GB could be local Time Machine snapshots. Time Machine will write the hourly backups to the free space on your hard disk, if the backup drive is temporarily not connected. You do not see these local backups in the Finder, and MacOS will delete them, when you make a regular backup to Time Machine, or when you need the space for other data.
See Pondini's page for more explanation: What are Local Snapshots? http://pondini.org/TM/FAQ.html
I have restarted my computer, but the information remains the same. How do I reclaim the use of the 300GB? Why is it showing up as "Backups" when it used to indicate "Photos"? Are my photos safe on the external drive?
You have tested the library on the external drive, and so your photos are save there.
The local TimeMachine snapshot probably now contains a backup of the moved library. Try, if connecting your Time Machine drive will reduce the size of your local Time Machine snapshots.

I have an older macbook pro and the hard drive is starting to go (making loud noises). i tried to back up to an external hard drive (my passport essential se) using time machine and the computer keeps shutting down. suggestions to complete backup please?

Sounds like you'll need to access that drive while it is not booted. You need to replace it anyway, so do that, then one way or another (ext enclusure, et), access it and copy files.
If you keep trying to boot it, you might kill it for good and not get your files, so just swap it out first.

I have a Toshiba external hard drive that i used to back up my Windows 7 HP -- I want to transfer files to my new Mac and it won't accept. Help?

I have a Toshiba external hard drive that I used to back up my Windows 7 HP -- I am not able to get the files off of it (pictures) onto the Mac. I am NOT a very technical person. IS there a simple easy way to explain and do this -- OR a simple way to just say it is not possible?

If you connect the external hard drive to your Mac does it show up in the Finder? If so, do the files you are trying to transfer show up? What happens when you try to move them over?
What kind of Mac are you using and what operating system does it have running on it?
Let us know, we'll keep helping you.
Best of luck.

I have installed a lacie porsche design 1tb external hard drive but how do I move things onto it so my mac speeds up

Hi Can anyone help? My Imac (about late 2008) was running very slow and I realised I had very little memory left on it so I was advised by the online chat buddy at Apple to buy an external hard drive. I have bought a lacie porsche design 1tb external hard drive which is great but how do I transfer things on to it so my computer works faster. I woudl imagine the buggest files I have are both photos and music (all bought form itunes).
Any help would be very much appreciated?
Thanks

How much free drive space is there? Right click on the Macintosh HD folder (or however you may have renamed it) and select Get Info.
The OS needs around 10 GB for its operation, but not all of that room is necessarily always needed. Depending on how close you get to the edge, creating more free space won't necessarily do anything to speed things up. It can certainy happen, but it's mostly a myth that low drive free space is a cause of slowdowns. This applies especially to zombie suggestions you may often see here to clear a certain minimum percentage of the drive out.
My recommendation would be to keep 10 GB free, plus room for anticipated expansion of your own files. So a ballpark might be at around 20-25 GB, but your mileage may vary, depending on how you use the computer.
If you have at least 10 GB free, then I'd say low drive space isn't causing your performance issue. Of course, moving things out isn't necessarily a bad idea either, if it's really needed--but you do realize that whatever you move out to an external drive will need to be backed up as well.
First backup everything, as this may be a symptom of a failing hard drive. This won't exhaust all the possibilities for the causes of the slow downs, but here are some things to start with: Open Disk Utility and select the drive, not the startup volume. What does it say for SMART Status, verified or not? You can better check to health of the drive with the demo of SMART Utility.
Next, open Activity Monitor. It's in the Applications folder inside the Utilities sub-folder of the main Hard Drive folder ("Macintosh HD", unless you have renamed it.) Go to the System Memory tab and take a screenshot of the bottom section only. (Screenshot is Cmd-Shift-4.) To insert it into your post use the camera icon above. Being low on RAM/memory can cause these kinds of symptoms. Like this:
In addition, see if there's any process or application consuming an inordinate amount of CPU. How much CPU is idle?

Can I have two Time Capsules in the same network, use one as Time Machine and other to expand network?

I need to purchase a divice to expand my Wi-fi network. I was looking at the AirPort Extreme, but a friend has a brand new Time Capsule for sale. So, for the same price of the AirPort Extreme, I´m getting the Time Capsule.
I already own one and using it as Time Machine and wireless router. If I decide to purchase another TC would it have any conflict with the one that I already have?
Is it possible to use one as Time Machine and wireless router and the other to just expand network and storage only (not as Time Machine)?

If I decide to purchase another TC would it have any conflict with the one that I already have?
No
Is it possible to use one as Time Machine and wireless router and the other to just expand network and storage only (not as Time Machine)?
Yes. The important thing to remember is that the "extending" Time Capsule must be located where it can receive a strong wireless signal from your "main" Time Capsule.

I have a an external hard drive formatted for Windows, and I want to move those files to a new hard drive formatted for both Windows and OS. Is this possible?

I just purchased a MB Air 13", as well as a Seagate Slim Backup Plus. I have an older external hard drive that I was using with a Dell laptop. I would like to get the files off of the older external hard drive, and onto the new Seagate drive. Is this possible? I'd also like to be able to add files going forward to the Seagate from either a PC or a Mac and be able to view/use them on the MB Air 13".
Thanks in advance.

You will have to format the Seagate external HDD to a format common to both Mac and PC such as ExFAT. That should allow you to transfer files from the old HDD and still allow you to use with your MBA.
Ciao.

My Mac is telling me that my disk is full. I have bought an external hard drive and have just listened to a youtube tutorial on how to move iTunes library to the external hard drive. If I do this can I still load new media on my Mac without the external?

my Mac is telling me that my disk is full. I have bought an external hard drive and watched a youtube tutorial on moving iTunes library to external hard drive. Will I still be able to use iTunes on my Mac for new media or will this now only work through my external hard drive?

To do this you need to learn the details of how iTunes works. For example, you just said, "leave my iTunes on my computer". iTunes is the application itself so of course it has to be on your computer. That said, I therefore don't know what you mean when you say leave iTunes on your computer. The phrasing of your question suggests to me, if I may be frank, you don't understand how iTunes works fully and we can't just give you a "do this" answer and have it work out. It would be too easy to make a mess of things.
What are the iTunes library files? - http://support.apple.com/kb/HT1660

What are all those iTunes files? - http://www.macworld.com/article/139974/2009/04/itunes_files.html
Where are my iTunes files located? - http://support.apple.com/kb/ht1391
Yes, you can download media and delete it again (but if it is from the iTunes Store there is the possibility you can't always download it again). Of course if you want to keep a copy you can archive it. I have done that with some files for which I have no room on my computer. I transfer them to an external hard drive and delete the reference to the file (but not the file itself) from my library. If I want a quick listen I go to the file on the drive and use Quicktime player or something else non-iTunes so I don't have to have it added to iTunes and delete again. I don't know if that is the solution you are looking for. I could leave the reference in iTunes but if the file can't be located by iTunes it will tell me there is a broken link = ! I guess I could live with that except I periodically scan my library for broken links and don't want it getting confused with ones I have done deliberately and ones suggesting I am really missing a file somewhere.
Another possibility is to make a second iTunes library for material you are archiving and only use that library when the computer is using the external drive. There are tricky aspects to dong that but it is a possibility too.
The simple solution for most people with computers with tiny drives (as most seem to be these days) is to put their whole iTunes library on an external drive and use it from there.

Partitioning Hard Drive for Use with Mac (Time Machine) and Windows

I have a brand new Imac on which I am also running WIndows Vista through Boot Camp (sweet, by the way). I have a large external hard drive on which I set up Time Machine easily enough. I would like to partition the drive somehow so that I could use half the drive to separately back up files on the WIndows side, but I can't seem to do this. Any suggestions? Is this even possible with Time Machine?

You can use Disk Utility create two partitions. Choose FAT for the Windows partition and Mac Extended (Journaled) for the Mac. One limitation of FAT32 is that you can't write files bigger than 4GB. You can reformat this partition as NTFS within Vista which will allow bigger file sizes but you won't be able to write to this partition from within OS X without other utilities. Also you can't write to the OS X partition from Vista without other software.
Time Machine will not be able to back up the windows formatted drive partition.

LaCie 1TB external hard drive can not connect to E4200

I have my LaCie 1TB external hard drive plugged into the USB-port of the Linksys E4200 so I can access that drive wireless.
However, in my disk management (via Cisco Connect), it does not show under Storage > Disk.
How can I solve this so I can access this hard drive from any computer in the network?
The drive is formatted in NTFS.
Thanks

Connect the hard drive directly to the computer and make sure that your computer can detect the hard drive.
If it is detected and working properly on your computer then connect the hard drive the USB port on the router.
Follow this link to setup storage device connected to E3000 router.

Ned to back up files. Trying to reformat a WD 1TB external hard drive but my utilities keeps saying "choose scheme from volume pop up menu.." also says cannot be modified. What can I do?!

Help would be appreciated! Before I upgrade my 10.6.8 OS X I need to back up files. Trying to reformat a WD 1TB external hard drive but my utilities keeps saying "choose scheme from volume pop up menu.." also says "this partition cannot be modified." What can I do?! Take it back to Currys! Many thanks

Select the Top Most Entry for that drive, it will be the drive model # and have the size listed, then go to the Partition tab and select One Partition from the Partition Layout area drop down. Then select Mac OS Extended (Journaled) as the format, if that is the format you want to format it AS. Then click the Options button near the bottom of that windows and select GUID as the Partition Table. Close the options screen and clcik the Apply button.
