My NTFS formatted external Toshiba drive is unreadable since update to Yosemite OS X 10.10.1

My portable external Toshiba hard drive is now unreadable on my MacBook Pro early 2008 aluminum computer. Since updating to Yosemite OS X 10.10.1, I cannot recover my files stored as Time Machine backups on my external drive. In the finder, it cannot be see under devices, however in Disk Utility, it is visible. The mounted partition is not viewable, however. My own native hard drive is 200 GB while the external hd is 500 GB. There's no creating a 500 GB image on my hard drive, in other words. I've tried the latest versions of Paragon NTFS and Tuxera NTFS with no avail.
How am I to recover my files, most importantly my Time Machine backups, from my external drive?

The first thing I realised when I started using a Mac was that it does not read NFTS files straight from the box. I had a Toshiba external drive as well and I had to copy all the files using a windows computer. Installed Tuxera on my Mac, partitioned the Toshiba drive into 2 sections one NFTS and the other Journaled.
When you copy files, do not modify the files as this may render them useless on your Mac.
I use the Journaled partition for Time Machine and the NFTS on both Mac and Windows file storage.
Do not format the Toshiba external drive otherwise you will lose all your data. Install a paid version of Tuxera on your Mac to be able to read the data. Some Toshiba hard drives come with a complete version of Tuxera.

What are these files you are trying to copy over?
If they are program specific and there is no program on a Mac to read them then you'll have to find either a Mac version of that program or one that does the same thing and can read those files.
The file extension should not change just because you connect a NTFS formatted drive to a Mac computer. A Word Document is still a .doc/.docx ad the same for all other office type programs. Music files with an extension of .MP3, or whatever, should read the same on both system. Same goes for all other files like images with a .JPG extension.
Yes I would network them.
I would not use Migration Assistant. There is nothing on your Windows PC that can be used on the Mac other than your personal data files. No programs or settings can be carried over from Windows to OS X.

Paragon also has a program (suite) that will convert NTFS <=> HFS+ without data loss (but have backup never use something wo one!)
And Pargon has kept up with Lion while others have not or have stopped development and works best with PC drive cases with low overhead and fast reliable copy operation.
The demo is also fully functional for 30 days.

NTFS formatted external hard disks?

does mountain lion supports writing on NTFS formatted external hard disks?

I'm getting immense slow-downs using Tuxera NTFS (latest release as of August 2012). I moved my home folder to an NTFS shared drive. Reading/writing to the cache while browsing in Safari is slow. Takes about 30 seconds for Finder to open my NTFS drive, takes about 1 minute to open an app and close the app. If I disable Tuxera NTFS and make my drive read-only, everything goes back to snappy performance (except for write-errors, since disabling Tuxera means I can't write to my home folder).
What shocks me the most is that if you visit the Tuxera community forum on their corporate website, none of their support representatives have helped their customers since the release of Tuxera NTFS for OS X Mountain Lion. It's as if the company realized they messed up, so they went silent.
I'm about to try the latest version of Paragon. I had it for OS X Lion, but it corrupted my entire drive after 2 months of use, which is why I tried to give Tuxera a shot. Here's to hoping Paragon has fixed their issues.

Can I install my time machine back up onto a properly formatted external hard drive?

I have a MacBook Pro with a 750GB harddrive, with 500+ Gb of data on it. Just before I traverse to Europe, I did a TimeMachine back up.
I now want to give my Mac to a friend, and buy a AirMac when I get home. Even if I get the one with the largest drive it will not hold the full 500+'back up.
I have an 8 year old Mac Book pro at home as well. It will be a few months before I can buy the new AirMac. So my question is ....
Can I install my current backup on a properly formatted external hard drive, and will it then run like a computer --until I get my new AirMac?
Thanks for your help (and please don't be too tough on me for what may see to de a dumb question)

HT1338 I was backing up my MacBook with Time Machine on my new (correctly formatted) external hard drive. It was going fine when my 2 yo knocked the hard drive. Now TM said "failed" and the Mac refuses to recognize the external hard drive. Help please?

I was backing up my MacBook with Time Machine and using my new (correctly formatted) external hard drive. All was going well when my 2 yo knocked the disk leading to a "failure" by time machine (Latest Backup: Failed). Now the MacBook will not even recognize the hard drive. I have rebooted, tried all I can think of, but no acknowledgement of the drive. The drive itself makes noise and vibrates as if working, but nothing from the Mac. Please help or $100 down the drain... Thank you.

FAT formatted external hard drive is not 'readable by this computer'

Hello support community
The problem: when I insert my 'FAT' formatted external hard drive (Samsung M3) into my mac book pro it comes up with the error message that says "the inserted disk is not readable by this computer" and I therefore cannot access the files.
The story (potential further details):
1. I had a problem with my mac where it took hours to load each time I turned it on, would only work when power was plugged in etc. so I had to reformat my mac hard drive (when I tried to veriify it said repair, that wouldn't work). So i'm starting with a recently reformatted, clean mac.
2. Before doing this I reformatted my external hard drive (whilst on windows machine) to FAT32 (so I can use on both windows and mac) so that I could back up my files.
3. I then transferred files from mac onto external hard drive and then also put them on a windows machine.
4. After reformatting mac hard drive when I then tried to transfer files back onto the mac I get the 'not readable' error.
The technical details:
Thank you very much indeed anyone who can help or can try and help
Cheers
Andy

Erase the drive and reformat using your Mac (Disk Utility)

Hey, can i clone my Macbook Pro internal hard drive and then paste it all onto a formated external hard drive, then make the Mac use the external as the primary hard drive?

If what doesn't work?
If cloning your internal drive to the external drive is not successful, I expect CCC will tell you so. Assuming that doesn't happen, you will have a bootable replica of the internal drive on the external drive once CCC has finished.
You can then do any of several things:
1. Replace your internal drive with a much larger one (320GB or 500GB, or even larger), and clone the external drive's contents onto the new drive so you'll have all your data in one place. Note that if you do this, you'll also need to buy an external drive that's large enough to back the new internal drive up on.
2. Boot from the external drive as a temporary measure while you clear at least 30-40GB of data off the internal drive, allowing you to keep using it and saving small amounts of data to it. The external drive will then contain the only copies of the files you've deleted from the internal drive, so you'll need a seond external drive large enough to back both the other drives up on.
If you can't comfortably clear a minimum of 30GB off the internal drive, you really need a larger internal drive right now, and you shouldn't bother fooling around with the inadequate one you have — you'll just quickly overfill it again.
3. Replace the optical drive in your MBP with a large conventional hard drive, giving you two hard drives inside the machine. You will then need one or more external drives large enough to back up both of the internal drives.
If you sense a theme here — back up, back up, back up — you are correct. It's flat-out foolhardy to own or use a computer without maintaining complete, up-to-date backups of everything at all times.

Time Machine - NTFS formatted external drive - reformat? If yes, how?

I have a USB external hard drive which is NTFS formatted. It shows up on my mac but Time Machine does not show it when I try to "Choose Backup Disc".
I suspect that the NTFS format is a problem. If so, how do I reformat this disc so it will work with Time Machine?

You are correct. You can read, but not write to an NTFS formated drive.
You can use Disk Utility to reformat the drive (and partition it if you like). Disk Utility is located in the Utilities folder, which is inside the Applications folder.
In Disk Utility, on the left side, select the external disk. Then select the Erase Tab. Give the disk a name and choose "Mac OS Exteneded (journaled)". I also recommend you take the extra step of zeroing out the drive by clicking on the "Security Options" button, and then choosing the second option down.
now you should be ready to go.
After you reformat the drive, you can partition it.
I have one partition for Time Machine, and one for me to save other files.
The Time Machine partition should be equal to or greater than the drive (or drives) it is backing up.
hope this helps

How to open my apple formatted external hard drive in my pc?

Hi guys. I have [or had...] an Australian Imac 27". I do not have the specifications now because the computer died last night. I was working and than suddenly everything slowed down. I tried to open Itunes and icon became an interrogation mark after I clicked it; in the aplications folder several programs had a red mark (sign) in their icons.
Well, I already did all kind of boots and resets and I think I probably my computer died [internal hd]. I live in Mali (Africa), thousands of miles from the nearest genius bar or apple stores.
My immediate problem is with my partitioned 4TB My Book II external hard drive [do not know how it was formatted]. It had in one HD my time machine and in the other some crucial files.
Now I am using a PC and I do not see the contents of the HD. Sure, the PC connects to it showing that there is a partitioned hard drive. But it does not open.
Do you think is a MAC OS - Windows problem? [fat x ntfs] How can I solve this problem?

Formatting a PC-formatted External Hard Drive to work in Mac OS

So I have a 300 gig external hard drive formatted for Windows XP with NTFS. I recently got a Macbook Pro and as it stands in Mac OS X the hard drive is read only. I can copy files from the hard drive to my Mac, but I can't edit files on the external HD or copy from my Mac to my external HD. This of course is a problem and so I need to reformat it to work in Mac OS. While I will not be using PCs anymore, if possible I would like for the external HD to be Mac and Windows compatible.
First things first I have to get all 300 gigs of files off the external HD in order to reformat it. This will be a pain but I have the means to do this. Once I get everything off, how and with what method should I reformat it to work in Mac? Should I use the HFS file system or MS-DOS? Also, what utility in Mac OS lets me reformat it. As I said, I probably won't be hooking up this external HD to Windows anytime soon, but if there is a way to format it in Mac to work with Windows, then fine.
So what exactly are my options here? I understand that I can format the hard drive in Mac OS with either MS-DOS or FAT32. I just don't know which is better/faster/more reliable in Mac OS, as I'm still a Mac newbie. I don't have files that are over 2 gigs as far as I remember, so I don't think that will be an issue. If it helps, it is mostly media files (videos, music). I've read up online about formatting a drive to work with Mac OS, but there's just so much info I'm getting confused. Thanks.

Thanks for the suggestions so far.
So from what people are saying, I can format the drive in Mac OS as FAT32 (aka MS-DOS) and it will work fine between the two operating systems.
I've been reading more though and it seems that FAT32 drives can not be larger than 130 gigs? Or is that just for partitions.
I have a 350 gig hard drive and I don't plan on having any partitions. Can I just format the drive as FAT32 in Mac OS and the whole 350 gigs will be available? There's so much conflicting info in articles I've been reading.
thanks

One Format External Hard Drive for Your Mac and PC...

I have Formatted my External HD Passport 500GB = (465.8) and split it in two partition Mac OS Extended (Journal = 232GB) and FAT32 (Ms-Dos-FAT = 232GB) and reformat to NTFS using Windows...
How to use one External HUD for your Mac and PC you have a PC and how to have two Partition in Mac OS Extended (Journal) and FAT (Ms-Dos-FAT)as you desire the size of your partition under application, Utilities and Disk Utility and covert the (FAT32) to (NTFS)using Windows Control Panel or just search by Start, search Computer Management or just right my Computer and format the second partition to (NTFS)
Tips for Mac OS Extended (Journaled) FAT32 vs NTFS, what works and don't work...
(1)Mac OS Extended (Journaled) Partition can't be use in Windows to transfer files but NTFS Partition can be use in Mac by transferring file from Windows to Mac and NTFS support for files over 4G in size...
(2)FAT32 can be use in Mac and Windows but with a limitation that a file cannot be transferred to a FAT32 partition if the file is larger than 4GB such as a video file and FAT32 file system performs more slowly than NTFS...
(2)Mac OS Extended (Journaled) can be use in Windows when you Reformat your HD to HFS+ by third-party app such as http://www.macdrive.com/ MacDrive for $50.or http://www.paragon-software.com/home/ntfs-mac/ NTFS For Mac 6.0 for $30...

I have many external drives I use between my MacBook Pro and my Windows PC's. I use a free NTFS driver for Mac OS-X to give me full read/write access to any NTFS formatted partitions when running Mac OS. I also use MediaFour's MacDrive v8 on some of my Windows PC's to access any HFS+ formatted partitions.
Most of my drives are formatted NTFS because I have more Windows machines than I have MacDrive licenses, and with the driver for Mac OS, they are fully accessible. I have a few drives I do keep formatted as HFS+ because I have encountered an app or two that don't work quite right when they don't get to write to files on an HFS+ partition (one of my backup programs is picky about this).
As said before, FAT32 is fully accessible between the two OS'es but it also has it's own limitations.
