External FW800 drive as main drive...Possible?

I was wondering if it is possible to run your computer off of an external fw800 drive, all the time. that should give your computer a huge jump in speed, right??
If it is possible, could you just set up a Mirror RAID configuration with 2 external drives thus backing everything up?
Dual 2.5 G5 Mac OS X (10.4.6) 4.5 gigs ram

Hi Raynor;
Mirror RAID is not a good solution for backup. What it does is it provides protection from the failure of a disk.
The reason I say it is a good backup solution is say you have an application that has a bunch of files opened. The application aborts and takes the files with it when it goes down. How can you recover? You can because the application will take the files off both disks because they are mirrored.
Hence even if disks are mirrored, it is still necessary to back up the data from the mirrored RAID array.

Mac and Windows shared external hard drive - possible?

Our set up is a Windows XP pc and iMac 20" and I hoped that we could back up both computers using one external hard drive - that way if the Mac failed we could still use the pc to access the files and vice versa. But having looked into buying one I'm starting to get doubts about whether it is possible. I just don't understand all the technical stuff. Can anyone help in layman's terms how we go about it?
Thanks
Jane

Try iFelix's excellent guides for Windows to Mac networking (link). I understand that he will do Vista versions as soon as possible.
A FAT32 formatted drive in a NAS Enclosure like this one (link) should suit you needs. Remember that a NAS drive will not have the performance of a Firewire connected drive so you do need to consider your intended usage.
kind regards

Booting from external Firewire drive--possible?

If I add a USB/Firewire card to my Beige G3 minitower (300MHz), can I then boot from an external Firewire hard drive on which I have installed Panther? A comment by Tina Garfield in another thread seems to suggest this is indeed possible. (I didn't want to "threadjack" that discussion, so I created this new one. I hope Tina sees it and can help me.)
Tina wrote the following:
Having Firewire allows you to have external drives,
which you will be able to boot from, and make
backups and maintenance especially easy.
I was under the impression that the Beige G3 can't see iadd-on Firewire/USB cards until the machine has booted from the internal hard drive. I really hope I am wrong! If it is indeed possible to have the machine recognize the external drive at startup, and there is something I need to do to enable this, please let me know.
Thanks!

Hi GeeKay,
Ditto to everything Grant posted, with an extra reminder to be sure to download XPostFacto 3.1 and not version 4. I believe on the XPF page ( http://eshop.macsales.com/OSXCenter/XPostFacto/Framework.cfm?page=XPostFacto3.ht ml ), the download for 3.1 is a little bit down the page.
If/when you buy an external FW drive be sure it has an Oxford chipset. If the description does not include mention of the the Oxford chipset, I would strongly recommend finding another external drive that does specify this. Our Beiges are very particular about what they will accept for external booting, and the Oxford chipset is a critical component.
Also, I've found, since I do partition my external firewire drives, that I can boot only from the first partition of the external drive, similar to the behavior of our internal drives. In addition, with one of my Beiges, my "helper" disk that I specify to XPostFacto to allow me to boot externally must be the first partition of my internal drive.
I don't believe that you can actually INSTALL to an external drive. I simply cloned my internal drive's system over to the FW drive. This can be done with software such as the free Silverkeeper ( http://www.lacie.com/silverkeeper/ ) or with shareware SuperDuper ( http://www.shirt-pocket.com/ ) which are both great for all backups. I happen to prefer SuperDuper because of its redundancy -- it explains EVERY step before you take it and then, even after you tell it to go ahead, it asks you again to be sure That's what you want to do.
Once set up, however, it is extremely cool, and helpful, to be able to boot externally. If your external drive is dual USB/FW, you will only be able to boot when connected via Firewire. None of the Beiges are USB-bootable.
Hope this helps, and keep us posted,
Tina

MacPro - External FW800 drives & auto power off

Hi, I have a new Mac Pro and am using two LaCie FW800 external drives with auto power off facility however when I power my Mac Pro down there is still power going to the FW800 ports as the drives down shut down. I am new to macs so is there any config setting to get round this issue?
Cheers
Paul

Don't believe there is but the power to the firewire port is a built in specification.
You could go to the Apple Developer site and look at their firewire SDK (there's many firewire applications, what they do I don't really know. Little too scarry for me.

[SOLVED]failure to mount external usb drive, possible hardware malfu

Please excuse me for posting this in the Arch forums, but I'd appreciate at least a point in the right direction. Every Google hit I came up with had a dubious solution like "reinstall USB drivers". I've never had an external drive fail on me yet, and I think this might be a sign of one. I recently moved and set up a 750gb WD external drive connected to this laptop running Arch and WinXP. Drive was working fine until this morning. I see it's entry in Thunar, but when I try to mount it:
Failed to mount "xxx".
WARNING: Couldn't set locale to 'en_PH.utf8' thus some file names may not
be correct or visible. Please see the potential solution at
http://ntfs-3g.org/support.html#locale

Please check '/dev/sdb1' and the ntfs-3g binary permissions,
and the mounting user ID. More explanation is provided at

I got an entirely different error msg in Arch before, suggesting a chkdsk but I don't remember beyond that.
In Windows, I get USB device not recognized. I've tried turning the thing off and back on, making sure it's connected and swiping cables, rebooting Arch, nothing. Is it fried? Also, how does one even run a chkdsk on a drive that can't be mounted in Windows?
Thanks for the assistance.

Thunar is saying it's a permission problem... have you tried manually mounting it?

External FW800 drives do not power up/down

When I was running 10.4.10 on my PowerBook, my drives would power up/down whenever turning the PowerBook on/off.
I just got a MacBook Pro 17" with Leopard and the drives work, but I have to manually power them on/off.
Is this normal or is there some setting that I am missing?
Thanks.

Make sure the integrated IDE controllers you are trying to use are enabled in the BIOS. You will want to put the optical drive on one IDE controller and the hard drive on the other. i.e. don't have them both connected on a single cable. Check the settings - both should be on master or cable select.

Booting Windows on an external (USB2) drive possible?

Hi everyone,
Is it possible to use the full MBA disk capacity (80GB) for Mac OS X and for those rare occassions when a boot into Windows is needed to run it from an external disk?
Thanks and regards,
Roman

Hi Roman,
only procedure I know of http://tubeshards.wordpress.com/2006/12/05/install-windows-to-a-macintosh-usb-dr ive/
Good Luck

Can MBP (with fw800) boot from external FW drive?

Does MBP allow you to boot from an external fw800 drive like the Powerbook did?
I am still using PB, and I used the CCC (Carbon Copy Cloner/SuperDuper etc) to clone my OS to an external fw800 drive. Matter of fact, as I am typing now I am running the OS from the fw800 drive. I need this because if my laptop's OS encounters problem I can boot up the comp.
Does the C2D processor work with CCC? I also notice apart from the PowerPC is that the Intel lets you boot into either OSX/XP or Vista via Bootcamp.
So, if it's possible to boot from an external drive, how does it work out? Because on the PowerBook, you hold option key to select either your main drive or external drive to boot to. But on the Intel, if you have bootcamp installed with OSX/Vista, would it show up 4 directories like this to let you boot to either one of these?
OSX (MBP HD) / Vista (MBP HD) / OSX (ext HD) / Vista (ext HD)
Thanks

Apple very plainly states that an Intel Mac can't boot a disk formatted on a PowerPC Mac, and vice versa. Each uses a different native partition table. Yet, each can read data stored on the other.
If you initialize the FireWire disk on an Intel Mac and use GPT as the partition type, Intel Macs can boot from it.
If you initialize the drive on a PowerPC machine, or you elect to use APM (Apple Partition Map) on an Intel Mac, then the drive will boot a PowerPC machine.

Running operating system from external hard drive

I know that is possible, and I have done it before when I have needed to run Disk Utility or to salvage files from an an mountable hard drive, though here is my question. My iMac just ran out of applecare, and I dont know if my boss wants to put the money into repair it yet. I am wondering the draw backs or real issues with running a mac natively off a external fw800 drive. I know its unorthodox, but if the repair of this iMac is allot, which I have a feeling it will be, this might be a a possible option, for a back up computer.

It will be a bit slower but it should work just like booting from the internal disk.

Issues with FW800 drive

Not entirely sure if this is the correct forum, but it's sort of a general OS question.
I had all my work (as a graphic designer) and my email on a FW400 drive, which I switch between my office workstation and my home-office workstation. Everything worked seamlessly - unplug from the office G5, plug in at home (exactly the same spec G5), and carry on.
I bought a FW800 drive (Icecube Pleiedes 300GB) and put all my work and email on that. I didn't pay any attention to the format when I bought it, and have since discovered its MS-DOS (FAT32) formatted.
The issue I have is that after I've moved the drive from one workstation to the other, my Freehand documents 'lose' their links to image files. I can link them back up but it's a real pain and can take a while if there's 20 or more images.
Is this due to it being FAT32 (and would reformatting to Mac Extended be worthwhile), or is there another factor here? An extension to the question would be "What are the disadvantages to running my external FW800 drive with FAT32 formatting?"
Thanks in advance,
Simon.

Welcome to Apple Discussions!
I'm not sure if it is due to the FAT32 formatting, however, it sounds quite possible. FAT32 is a format primarily used for PC drives. And PC file naming conventions are different than Macs even in FAT32. As such names that would be allowed on the Mac system won't necessarily work in FAT32.
In the future don't rely on any one drive to keep your files. And always format the drive in the Mac format unless you have reason to share with PCs a lot. In which case, don't use that drive as a backup drive, and simply as a means to transfer data. Use another drive to backup the data to.

Sleep interferes with Time Machine and file writes to FW800 drives

I have leopard installed now on 5 systems. If a system goes to sleep while i am either copying files to an external firewire 800 drive or using time machine for its initial backup to the firewire 800 drive the file copy/write will get hung up and not resume when coming out of sleep. I have also had a problem where the screen gets crazed and locks up while writing to external drives and the sleep state.
I have gone in and selected never as the sleep frequency and this has all stopped.
I did not have this problem writing to the same Firewire 800 drives with TIGER.
Anyone else seeing this problem?

I am having a very similar problem. Time Machine starts up fine (albeit a little slow). It starts backing up files. I have the machine set to not go to sleep and I have the option to put drives to sleep turned off. I do have the screen saver kick in after 30 mins, though. As soon as that happens, the backup process seems to halt.
FWIW, I am backing up to an external FW800 drive. I have a FW400 enclosure I can try. I'll give that a whirl later tonight.
This is very annoying. Very un-Apple.

Portable External Hard Drive / Steroids for MacBook Pro

Hi. I recently purchased a (Non-Retina display) 13-inch, Mid 2012 MacBook Pro.
Processor: 2.5GHz Intel Corei5
Memory: 4GB 100 MHz DDR3
Graphics: Intel HD Graphics 4000 384 MB
Software: OS X 10.8.2 (12C54)
I love my new laptop, but am not exactly tech-savvy. I'm pretty computer illiterate, so I don't exactly know the difference between USB 2.0/3.0 or Firewire 400/800. I know what I want to do, but I'm not sure if it's possible. Basically, even though I love my MacBook, I'm curious if I can love it even more and want to know how to max out its potential. Eventually, I want to:
A.) install the maximum amount of memory and internal hard drive capacity possible.
B.) get the largest, fastest, yet PORTABLE, external hard drive possible. I've got a ton of music in iTunes, and I want to get my huge DVD collection digitalized. Something in the TB range. I keep reading mixed reviews on WDs and Apple's Time Capsule.
Any help will be much appreciated,
Mike

Hi Myke,
If you want to shop for a bigger hard disk or more memory, I recommend you go here: OWC / MacSales
Their prices are about as good as you're going to find, but more importantly their Mac support is superior, especially if you are not completely confident in knowing exactly what you need to buy. Macs are particular about memory but if you buy from OWC they know what to supply and will guarantee it will work.
The ultimate upgrade is an internal Solid State Drive but these get expensive in a hurry.
The Time Capsule is not a portable external hard disk. If you want an external portable HD, shop for one at OWC.
I have heard mixed reviews on WD also, but the same mixed reviews apply to all consumer grade hard disks these days, without exception. Basically, they are all cheap. Consider them disposable, which means you should always have a backup. Time Machine is included with your MacBook Pro and is as easy to use as plugging in an external hard disk. Time Machine does the rest. Use it! There is no excuse not to.
USB is preferable to FireWire these days.

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 verif

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.

Use time machine to backup external hard drive (not main one)

Hi all,
I've searched for information on this and getting nowhere. Not sure if it's possible, but I have two USB hard drives now as I've run out of space on my laptop. So therefore I really use one of the hard drives for my main storage and drag files across to the other one to back that up.
It would be easier if I could just use time machine to back up the one external hard drive to the other. I don't want to just replicate what's on my laptop hard drive.
Does anyone know if this is possible? Would appreciate any help.
Cheers
Paul

Thanks for your reply V.K. much appreciated.
I have gone into the options and I can see my external drives there, but for some reason I can't remove them from the exclusion list. I can add and remove the Laptop HD from this list, but for some reason the "-" button becomes disabled whenever I select the external Hard Drives.
Is there a reason for this? I've been using both drives for a while, so they are both Mac formatted.
Thanks again.
