How to Format external drive previously formatted for NSLU2

Windows XP.
I've had two external hard drives connected to my NSLU2 for several years. Always worked properly. Nevery any problems accessing files from either drive. Now, I'd like to remove one external drive and no longer use it with the NSLU2 (Disk 1). I just want to use it as a "regular" external drive and connect it directly to my PC by USB. When I plug it into my PC, it is not visible in Windows Explorer. When I right click "My Computer" and select "Manage", I can see it in the "Disk Management" section, but there is no drive letter assigned to it. It has partitions. When I right click on any partition, the "Format" option is grayed out and cannot be selected. Also, the "Change Drive Letter..." option is grayed out and cannot be selected. How can I format this disk back to whatever it needs to be in order to use it as a regular external drive? NOTE: I do not need to keep any files on the drive. I've already transferred the files I need to another drive. Thanks!

Never mind. I figured it out. I downloaded a free utility for formatting large drives in FAT32. The utility ran a quick format in just a few seconds and then the drive became available in Windows Explorer where I can now perform a complete format or just use as-is.

Format External Drive - From Mac for Windows

I have a Maxtor One-touch that I need to back up a bunch of data for a Windows XP user. After some research, I thought that formatting the drive in the MS-DOS (FAT) format would do it, however, after doing so and moving all of the data, I have tried the Harddrive on a PC running Windows XP. The drive doesn't mount.
The external drive is a PC/MAC compatible version. Am I overlooking anything? Is there something I need to do in windows to access the drive.... because it's not obvious.

Hi Christopher,
follow either Templetons advise or (if not possible) use Disk Utility and set the partition scheme (behind the Options button) to MBR (Master Boot Record) and use MS-DOS (= FAT32) as file system.
That should also do the trick.
The 'standard' partition scheme on Intel Macs is GPT (GUID Partition Table) which can sometimes lead to the effect with Windows PC that you observed.
Hope it helps

How to format external drive as NTFS?

I have a lot of files on my mac, and my external drive is formatted in FAT32. I can't put files larger the 4 GB on there. How can I format the drive as NTFS? All help appreciated!

Also note that even if you do use a Windows computer to format the drive as NTFS and then put it back in your Mac, you can't write to it without installing third party software. As installed, OS X can only read NTFS.
As Niel noted, Mac OS Extended is the best choice, as long as there's no reason for the drive to be accessible from a Windows computer. If it must be NTFS, then you have these choices for the Mac to enable write access.
A commercial product is Paragon NTFS for Mac.
There are now two versions of the open source NTFS-3G software for OS X. NTFS-3G is the free version, which only works with the 32 bit boot kernel. This version also requires installing MacFUSE. A separate component needed for the free NTFS-3G software.
Tuxera, which provides the funding for the free NTFS-3G has their own paid version. Tuxera NTFS for Mac. This version supports both 32 and 64 bit boot kernels. But NOT the newer 64 bit only kernel of some newer Macs. Tuxera's version eliminates the need for the separate MacFUSE installation, and is faster at accessing NTFS drives.
Edit: Checking Tuxera's site, it looks like they've fixed the issue with the newer Macs which will only boot 64 bit. The note they had on their site at one time about it not working seems to be gone.

I really need to speed up my IMAC. I purchased a new external drive specifically formatted for apple. I also would like to move some other media (movies and music) to this external drive. What is the best method for this?

Please help...I need to delete iphoto pictures and back up to external drive without losing pictures. I have the external drive and would like to start this process. Can you help?

Formatted for Mac is not a format - for iPhoto you MUST verify that it is formatted Mac OS extended (journaled)
and putting your iPhoto library on an external drive is NOT a backup - you MUST have a good backup plan like Time Machine running or you are 100% guaranteed to lose your photos sooner or later
Moving the iPhoto library is safe and simple - quit iPhoto and drag the iPhoto library intact as a single entity to the external drive - depress the option key and launch iPhoto using the "select library" option to point to the new location on the external drive - fully test it and then trash the old library on the internal drive (test one more time prior to emptying the trash)
And be sure that the External drive is formatted Mac OS extended (journaled) (iPhoto does not work with drives with other formats) and that it is always available prior to launching iPhoto
And backup soon and often - having your iPhoto library on an external drive is not a backup and if you are using Time Machine you need to check and be sure that TM is backing up your external drive
other media questions need to be ask in the forum for the software you use for them - this forum is only for iPhoto and the above instructions are only for iPhoto

Transfer files from Mac formatted external drive to PC formatted drive

i need to transfer quicktime files (that were captured from video with FCP) to a PC formatted external drive (for editing them in after effects on a PC). the files can be transfered by burning them on a DVD, but that will take a very long time and waste many DVDs because i have 60 GB of material... can this be done (without having to purchase expensive software)?

thanx tom,
first of, i like that you made the link appear as one word. how did you do that? it's really cool!
i downloaded the program, but i'm not sure how to use it... reading the guide just made me more confused... if i understand correctly, it will automatically reformat ALL my files to NTFS-3G ones, which are not as stable... i'm a little scared to install it... though i may have totally misunderstood what it says. i see mostly black when i try to read these kind of things...
anyone out there have experience with this program?

Odd question regarding files on a mac-formatted external drive...

I have recently purchased a Western Digital external HDD (1TB) and have synced it with my mac as a time machine.
I have also, however, moved a bunch of files from my macbook, including family movies, DVD's I've ripped, a lot of my music collection, work files and some games.
This has worked brilliantly thus far.
BUT! I have my MBP bootcamped for some boring programs for work etc. but want to be able to listen to music/play games/access files through the WD HDD... This may be obvious to many people; but it wasn't immediately obvious to me: Because the External drive is formatted for Mac, as well as 'time machine-d', it refuses to be recognised by the PC...
Thus, my question is:
Is there a way to move files from Mac to PC (bootcamped) through an external drive that is formatted to the Mac.
If not, is there a way to move files from Mac to PC through the bootcamp disc on the Macintosh Desktop. I understand that files smaller than 4 gigs can be moved across NTFS (?) but some of the files for my work stretch as far as 11 gigs...
Any help with this would be greatly appreciated! I've been looking around the net for the past week... It's time to be proactive...
If any more info is required, please let me know.
Ollie.

Hi Ollie,
with the BootCamp 3.0 Drivers Apple introduced a read access from BootCamp Windows to Mac OSX partitions, but this seems to only work with internal harddisks not with external ones.
MacDrive is the choice get full read and write access on Mac OSX partitions/harddisks while in Windows http://www.mediafour.com/products/macdrive/
For a simple read-only access HFSExplorer can be used http://hem.bredband.net/catacombae/index2.html
The 4GB size limitation is only active on FAT32 file system not on NTFS, but Mac OSX itself can only read from NTFS partitions not write to them without additional helper like NTFS-3G http://macntfs-3g.blogspot.com/
So, with you scenario (external HD = MacOS file system) it seems that MacDrive would be the way to go.
Hope it helps

How to use External Drive for Users Directory

I just did a clean install on my Mac Mini - I have over 4 TB of storage attached, but the main drive (160 GB) keeps filling up. What is the best way to have the Users directory located on an external drive?
Thanks for your help,
Chris

Think about it for a second. What would happen if that external drive wasn't connected for some reason? Maybe it died the night before, as external drives have a habit of doing. How are you going to log into the system?
If the main drive is filling up, it says that you aren't making effective use of the attached storage. There's nothing saying you have to keep video files in the Movies folder, and music in the Music folder, etc. Find some things, that aren't your user profile, and move them to your external storage. Or consider putting in a larger internal drive.

Those look alot like file names and not infection names. I don't find any reference to anything like that on Norton or VirusTotal. Since you said these were Trojans, I would expect to see "Trojan" as part of the infection name.
".jar" files are executable Java applets. The random alpha-numerics would seem to indicate a cache file, likely from a browser with Java enabled. And we all know what ".zip" means.
Worst case is that you had Java enabled in a browser and were infected by one of the late variants of the Flashback Trojan over a year ago or one of a couple of other attacks using the same vulnerability but targetted against a small number of political sympathizers. Much more probable is that thes were Windows only Trojans. Hopefully you have a fully up-to-date OS X, including Java, and have disabled Java in all your browsers by now.

How Big a Backup Drive is Needed for a 500 GB Internal drive?

I just bought a MacBook Pro (15 inch, mid 2012) with a stock 500 GB internal hard drive. I want to buy a USB 3.0 external drive for a Time Machine backup drive.
Bearing in mind that I don't keep photos or any significant quantities of big visual media (movies, etc.) on my Macs, it will take several years to even fill my internal drive halfway.
How large an external drive do I need for a backup? One vendor has suggested 1 TB, but I wanted to check with the community before purchasing.

How to format external drive for mac AND pc use

hi
i want to format my external drive so i can use it on my mac and on pc's as well. i've gathered that the MS-DOS format is the way to go. my question is this: would this create any problems for my mac then?
can i partion one part for ms-dos and part for macos extended?
cheers

There are a couple of disadvantages with formatting a
disk as FAT32. Firstly, there is a limit on the file
size for FAT32. I think it like 2 GB so if you
capturing video the results will probably not fit
into this file limit. Secondly FAT32 will not be
bootable. I alway clone my system to a backup disk as
bootable. That way if anything goes wrong with my
system, I can just boot from my backup disk and fix
it.
The problem with doing this though is that the drive will not be usable with Windows (which was in the original posting) unless you use the third party MacDrive software on the PC.

How to format external drive for use against windows and mac

Hi.
Please bear with me, a possible MAC newbie here
I'm about to buy the 13" Mac Book Pro (after ditching the Lenovo X301 because of a super slow processor, slow FSB, slow intel graphics).
But I have a couple of questions before I buy this Mac Book Pro.
NOTE:
My main OS (stationary pc) is Windows, and will probably be so for a long time.
But I need a lightweight laptop while on the run, and could not actually find any other one than the Mac Book Pro that met my requirements.
I'm using Adobe Lightroom for indexing and managing images on my windows stationary computer and will also use Lightroom on my Mac Book Pro.
I'm to use an external HDD for this purpose and will need to be able to both write and read to/from that HDD from both MAC and Windows.
Export lightroom library to External HDD from Windows (thumbnails + keywords).
Import new images and edit keywords etc from mac book pro in lightroom.
Import changes into my windows library version after been edited from library in mac book pro.
What options do I have when it comes to formatting that HDD?
What will the PROS and CONS be for the different options?
Note (I'm not to switch to Aperture (my main computer is still Windows))
Regards

Hi.. and thanks for that answer... another related here:
I'm to buy this external drive:
http://www.lacie.com/no/products/product.htm?pid=11038
This page:
http://pc.wikia.com/wiki/FAT32
tells me that windows XP will only format FAT32 to max 32GB,
will my upcoming MAC book PRO be able to format that whole disk using FAT32?
Or do I have to use something else to format it with?

Formatting External drive for Mac05

I am trying to format a Western Digital external drive for Mac05 Extended (journaled) in order to transfer photos from my I photo program to free up space on my hard drive, as per suggestions received in this support site. I have downloaded information from Western digital, but it is coupled with 'How to partition and format an internal slave drive or an external drive in a Mac OS X." Once I select Disk utility, the drives are not displayed. Anyone have any suggestions how to format the external drive for Mac05 Extended (journaled)??

Can't format external drive for Mac

I got an external Seagate Freeagent 750GB drive to use with my new Mini. It came formatted as a windows FAT volume. Since I don't have a FW400 to FW 800 cable yet, I have it connected via USB. When I try to reformat as a Mac drive (with any of the 4 case-sensitive / journaled options), I get an error, but I can then reformat as FAT. Does anyone know how I can format this drive as mac and what the problem is?

It may have something to do with the partition scheme. There are at least three different schemes. One is used for windows formats (so you can use FAT32 or NTFS format), one is used for Intel Mac (probably GUID, not sure), and one is used for PowerPC Mac (probably the Apple Partition Map, again not sure). I don't know whether it is smart enough to choose the appropriate scheme for you when you have selected a format for your partition. Try to select the right scheme for Intel Mac first, and then decide on the format on each (if you have more than one partition on that disk) partitions.
I think you have to make sure the format is compatible with the scheme, especially when you have multiple partitions on one disk. You can't format one partition to FAT32 and another to HFS+, although it will try to do something, but it will end up with error.

How to format external drive as MS-DOS (FAT)

How do I format the external drive as MS-DOS (FAT)?
I followed the instructions and have Disk Utility open for the external drive. Then > Erase > changed format from Mac OS to ExFAT and did the same with the RAID tab. But this does not change the Format from Mac OS Extended (Journaled).
Thanks in advance for any advice..........It's never easy is it?

(3) Boot Camp 4. downloaded to 16-GB flash drive, which is recognized in Windows but will not install due to following prompt: "The version of this file is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need an x86 (32-bit) or x-64 (64-bit) version of this program, and then contact the software publisher." This flash drive is formatted as MS-DOS (FAT), although ExFAT was an alternative.
OK, that does not suggest a disk format problem, but it does suggest that (as it says) you have the wrong Boot Camp version, or the wrong Windows version. ie, you have a 32bit version of Windows installed and you may have a 64bit version of Boot Camp on your Flashdrive.
I'll be back shortly, I'll get links for the various versions of Boot Camp, if there is no 32bit version for your Mac a reinstall of Windows is indicated, the 64bit version though.
OK
Even better, here is a link to a page with all the versions, if you click the version name a description will be displayed, find the correct one for your Mac and version of Windows.
Finally this page contains a model by model breakdown of which version of Windows will run on which model of Mac.
