Change partitions on disk with NTFS and Mac OS Extended

I have a 1.5TB external drive formatted with 3 equal size partitions: 1 NTFS and 2 Mac OS Extended formats, each one ~500GB. I'd like to remove the NTFS partition and use the whole drive for the 2 Mac partitions. Could I copy the NTFS data to one of the Mac partitions, then delete the NTFS partition, and then enlarge the two remaining partitions, of course without losing the information that's already on each of them? My system is OSX 10.7.5 -- Lion.

Probably maybe, with a fair wind & some luck…
It depends on a few factors, such as the order of the partitions on disk, how the disk was originally created, what partition scheme it uses (e.g. GUID, Master boot record…). It also depends on if all that data can be crammed into an existing partition.
I doubt you want to hear this, but it is the safest option… backup the data on every partition before you begin modifying the disk structure.
You have nothing to lose with solid backups on another disk, disconnect it to be extra cautious.
If this disk fails to repartition or you find that the 2 remaining partitions won't not expand to fill all the free space (it just happens sometimes) you can create a new partition table & start over.
Disk Utility may also complain when you try to resize or delete a partition - sometimes it waits until the last button is pressed to begin a task only to tell you something isn't possible!
I wouldn't attempt this 'copy, delete, resize' unless I could afford to lose all the data on this disk, it should work, but there is too much room for error.

Want to use a Lacie External Hard Disk with Windows and Mac? Can I?...

Hi, I've just purchased a Lacie Extreme D2 external hard disk, I'm looking to use it to move film clips from my Mac G5 to my Sony Vaio laptop. I'll connect the Mac using Firewire 1 and the PC using USB 1.
I understand there is an issue with setting the compaitibility of the hard disk to either Mac or Windows format but I'm wondering if I can set it to both, so it's possible to transfer these files? The hard disk is Windows and Mac compatible but does it have to be partitioned a certain way?
Any help is much appreciated.
Thanks,
Alex

Format the drive as FAT or use the Mac format (HFS Extended) and install MacDrive on the PC.

Paragraphs help the reader, just saying.
What are you actually trying to do? Why do you need "DVD size" folders if you're creatng an Archive on an external hard drive?
Also, I understand burning folders instead of individual photos or albums gives you more space on a DVD.
It makes no difference at all.
How can I keep the captions on my photos (not events) when I print or transfer to a new folder?
You can export while writing the metadata to the file in most cases.
Tne only way I know is to copy photos from the Windows to folders on my HD, then copy and paste photos or albums or events to HD, then create a new folder and fill it to the appropriate DVD size.
HD? Another HD? You use HD there in a way that makes no sense. What's the point of 'DVD size'?
I also thought I should download future photos to my Canon programming that comes with EOS cameras and edit and then decide which photos to save to iPhoto library and which to save only to my archival HD?
Does this have any relation to the previous questions? You know you can delete from iPhoto, right?
You're somewhat confused and you need to
1. Decide what exactly you want to do
2. Then go about it.
If I understand you correctly - and there's no guarantee that I do - the easiest thing is to bring all your Photos into iPhoto and do everything from there.
You can have an archive on an external disk, you can sort and select and edit with or via iPhoto

Why do I need to reformat and erase backups on an external backup drive that I have been using for over a year, when I get this dialog box? The backup disk is not in Mac OS Extended (Journaled) format, which is required.

Nforce420: How can I upgrade BIOS on a computer with NTFS and no flopp

I have a multimedia PC in my living room hooked up to my TV and I am planning to use it as a PVR, MP3 jukebox, DVD player and photo album.
I build this machine in a small aluminium case, with the minimum components. I chose the nForce as the platform for this machine to minimise the number of components (and noise/heat).
I'm running Windows XP with NTFS and there is no floppy drive in this system. Do you guys have an idea about how I can upgrade the bios from 2.0 to 2.4 (or 2.6?)?
Thanks in advance

Well, if you have any kind of internet connection on the computer, then MSI LiveUpdate is the way to go. I had the same problem after I didn't quite plug in my floppy right the other day -- the burning smell was exhilirating but my computer was fine. I have only NTFS partitions too and no floppy, but with an Internet connection it was easy to update the bios.
For some reason LiveUpdate wanted to tell me that the latest BIOS is 2.4, so if you navigate to C:\Program Files\Setup Files\MS6373v240 and replace the BIOS image files there with the 2.6 ones you downloaded, and run Winflash.exe, it will flash you to 2.6.
Alternately you could just download all that stuff on another computer and burn a CD with it. You could make that CD bootable or you could boot off a Win98 startup CD or something and put your CD in after the computer boots up...not really sure how well that would work.
Winflash has worked fine for me the three times I've used it (from 2.4 to 2.5, then back to 2.4, and now to 2.6).

What payment method are you trying to use? Prepaid debit cards by chance? Apple does not accept prepaid cards.

Recommendations for Semi-Pro or Pro HD Video camera to use with fcp and Mac

Recommendations for Semi-Pro or Pro HD Video camera to use with fcpX and Mac with auto settings and ability to override, need to add external mic or 2. Am one person crew so needs to be easy to use.

And check out the Panasonic AG-AC90. Very good specs for a prosumer unit. Everything in the semi-pro area will involve trade offs for sure. Key thing is to study up enough to know what your needs are vs what trade off are involved in the various models. The ag-ac90 trade off (one of them) is diffraction limited sharpness.

Lenovo Wireless Headset W770 compatibility with Linux and Mac

Hi,
Can someone provide me information on Lenovo Wireless Headset W770 compatibility with Linux and Mac distributions. On the product overview page under Software Requirements, only Windows is mentioned. http://support.lenovo.com/en_US/downloads/detail.page?submit=true&componentID=1343112653906&DocID=PD...
Please let me know if the headset can work with other distributions as well.
Thanks & Regards,
Keya
Solved!
Go to Solution.

I just received W770 and tried it on a PC and it worked. But when I plug the USB receiver in a macbook air (2011 MAC OS 10.6.8), it didn't work. The message I got is that MAC can't recognize the "keyboard" and asked me to press the shift button on the unrecognized keyboard- which I guess meant that the MAC treated the USB dongle as if it were a wireless keyboard of some sort. Anyway, would appreciate it if you could let me know how to make it work on MAC. The previous statement saying that it would work on any Lenovo machine regardless of OS is kinda of unclear - do you mean that it would also work on lenovo running MAC OS (is there any Lenovo running Mac OS?). Thanks.

HT4906 The backup disk is not in Mac OS Extended (Journaled) format, which is required.

Time Machine error!
The backup disk is not in Mac OS Extended (Journaled) format, which is required.
And what's Time Capsule?

If you're trying to use Time Machine with an external hard drive the drive must be formatted OS X Extended (journaled);
So use Disk Utility to reformat the EHD and then open Time Machine and select the drive again.

Partition disk with fdisk and windows can't be installed.

so I have been running ArchLinux for a few days, have successfully trashed my partition table once and lost everything on my systemdisk sh*t happens thats why I have one drive as system disk
Anyway, since all my partitions died I thought I could repartiotion the disk (I had been thinking of doing it anyway). So I booted the ArchLinux install disc once again and then partition my disk something like this:
/dev/sda1 - ntfs (for my windows xp)
/dev/sda2 - /
/dev/sda3 - /home
/dev/sda4 - swap
All partitions are primary since I only need 4. So off I go install Arch, config everything and so on. Then today I decided to install windows, so I reboot and insert my windows disc and press any key too boot from the CD and then Nothing. My computer just stands there black screen my CD spindowns and stops my HD is chewing away like crazy.
I have no idea what to do, thought my disk has been broken or something so I open my computer case and disconnect all disks attach my secondary disk as my only one just to see if the install starts and so it does (but I don't install because it is wrong disk ). Then I thought it might be the sata-cable who is bad (happend before) so I tried another one and my systemdisk again, but no luck. After that I boot archlinux installdisc and clear my entire partition table, recreate one 20gb ntfs partition make sure it has boot-flag and reboot. Still no luck, so back into linux and remove everything on that disk and reboots. And now the installation finally starts but instead of creating a partition during xp-install I reboot linux once again to create it in fdisk, and once again the installation doesn't start. So now I have cleare the entire disk from partitions again and created my XP partition during the XP install.
WHY can't I create my partitions by using fdisk in linux? and yes I did create ntfs filesystem on my partition (mkntfs or what the name was, exists on archlinux ftp install disc)

Yes I do know Windows will overwrite the MBR but that isn't the problem and overwriting the MBR doesn't destroy my partitions just uninstalls lilo (yes I use lilo, to lazy to learn using grub when lilo do the job god enough for me)
My problem is that I can't start the windows install. Here is what I did after ArchLinux was installed
1) Start my computer
2) insert windows install CD when computer is doing the BIOS startup stuff
3) Now I get a message to press any key to boot from the CD, this is from the Windows install CD and I do press the key.
4) Normally I would get into the Windows Install program here But now I Don't, NOTHING happens.
Then I started my search on what was wrong. I have installed Linux many times before windows and I have reinstalled windows lots of times without the need of reinstalling linux or repartition my drive.
In short, after lots of testing my computer does not start the windows install if my first disk has been partitioned with fdisk in linux (havn't tried other partition tools in linux).
EDIT: The windows install starts if I boot into linux and use fdisk to clear the entire drive from all partitions, yes no partitions at all not even one for windows.

HT1178 Can you backup to same time Capsule with PC and Mac

How do I backup to same Time Capsule with both PC and Mac

- backup iMac to TC and hook up HD to USB port on TC to backup PC laptop
Hmmm not better IMHO.. as long as you disk image the TC.. and the amount of space you have far exceeds total usage on both computers.. For the TM backup on the Mac you want TC area to be at least 3x the used space on the drive.. leaving out VM or bootcamp partitions if you use them.
Plus enough space to back up the PC laptop a couple of times over.
USB hard drive is fairly slow.. but should be ok for backup over wireless.. just be aware you cannot unplug the USB drive and use it direct unless you format it FAT32 which is very poor format. So first backup is going to be slow.
- backup iMac directly to HD thru firewire and backup PC to HD hooked up to Airport Extreme
If you don't already have a TC then this is fine. Firewire local disk is much faster than network backup even over gigabit.
Any of your options would work ok.. doing disk image on the TC is most difficult to get working and limits the hard disk space. Balance out what you already own network wise with what you need.. there are plenty of routers now with USB ports that will deal directly with windows using NTFS.. if you end up using firewire local disk to the imac..

Can i use external drive with pc and mac??? files be recognised by both??

hi
i have two external hard drives, with stuff from my pc on them.
can i plug them into my macbook? and just copy files?
usb hard drives.
one i think is one or the other, mac or pc, not both at same time, unless i partition and format i think. maybe the other one too.
i have a 8gb file on my pc, im trying to get into my macbook.
how can i???
i have a 160gb ipod, its only 30gb full, and pc says not enough space on it.
why is this???? the file is only 8gb......and theres over 100gb free on my ipod.
anyone help?
cheers

If your iPod is formatted FAT32 there is a 4 GB file size limit. Obviously an 8 GB file exceeds the limit.
In order to use any drive on both a Mac and a PC with full read/write capability the drive must be formatted MS-DOS (FAT16 or FAT32.) A drive formatted NTFS is read-only on a Mac unless you use third-party software such as MacFuse with NTFS-3G or Paragon NTFS.

Can a portable USB 3.0 HDD be partitioned and formatted FAT32 and Mac OS Extended?

I wish to use a portable HDD on a Windows laptop and also my iMac.
I realise that if I format it as FAT32 it will work on both.
Unfortunately I also need it to work with Final Cut Pro X . . . but FCP X can only recognise Mac OS Extended drives.
So will I be aple to split it into 2 partitions with one formatted as FAT32 and the other Mac OS Extended?

For what it is worth, I have an internal drive that is formatted thusly:
/dev/disk2
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *1.0 TB     disk2
   1:                        EFI                         209.7 MB   disk2s1
   2:                  Apple_HFS Lion                    531.2 GB   disk2s2
   3:                  Apple_HFS TimeS                   369.0 GB   disk2s3
   4:       Microsoft Basic Data FILES                   99.4 GB    disk2s4
When I boot into Windows 7, which is on still another drive, it recognizes the FAT 32 partition fine, as does Mac OS, and both can read and write to the partition. It has been awhile since I set this up, as I recall I may have had to reformat the FAT 32 partition from Windows (originally formatted it in Disk Utility). Sometimes Windows just doesn't like the format as done by the Mac. Anyway, the point is that it is not the first partition. You might try fiddling around with the new drive and see if it really makes any difference. Also I can boot Lion from that drive if I want, because it is GUID Partition Table.

Checking disk with sccli and asm

Hi all,
I'm a newbie with sccli. I'be been checking what disks, logical volume, physcial volume, lun, partition in the sccli have been used for the asm and what is disk is still available in the OS level.
Will you please advice on the command and steps to check this.
and any document links.
thanks
