Can i use 1 external disk for TM with several Macs ?

Hi,
is it possible to use 1 external disk with TM for several macs ?
Would it result in something like that in this case:
Backups.backupdb -> Mac1
Backups.backupdb -> Mac2
or am i forced to have a single TM disk for each mac ?
best regards
fidel

Hi,
thank you both for the quick reply.
The partition idea is not that bad, but as i am not using TM to do a full-backup, nor do i run it daily the disk-usage is not that important for me.
Till now i have done about 15 backups on my mac pro and the data is < 30 gb
(based on the excludes)
basicly i want to use TM only for the case that i need to reinstall Leopard (cause of a broken hd or similar) as i assume that i can use the TM-data in this case.
the idea to setup TM for restoring deleted files is nice, but i dont really see a reason in my case
best regards
fidel

Best filesystem format to use on External disk for windows and OS X access?

I have a external harddrive (250GB) that I want to be able to access in Windows Vista (through bootcamp) and also in OS X. Whats the best format for the filesystem on that drive so that I can access it both OS's?

Hi,
I have been looking for this post!.
My girlfriend has a windows based laptop. I have a macbook pro and we both need to share an external hard drive (Maxtor 3200, 300gb). The external hard drive is currently formatted as NTFS. When I tried to access the drive from my macbook pro, it gives me an error, basically asking me to initialize the drive, which I won't do (got lots of data in it). After some net research, and reading this post I now know that I have to format it in fat32. I guess that my questions are:
Is this the only solution? How stable is the fat32 format? Can I use another file format for two different environments Mac OS and Windows?

Can i use ANY external CD/DVD drive with the NEW mac mini?

We just got the newest Mac Mini and want to get an external drive for importing and burning CD's and DVD's.
Can we use ANY external CD/DVD drive or do we NEED to use the "Apple MacBook Air SuperDrive."
Thanks
Eliot

Maybe.
I've had some situations where a non-Apple DVD drive would not do a particular job. When I tried the same project with the Apple SuperDrive everything worked perfectly.
This is an area where I would not try to save money.

Can I use an external HDD for Boot Camp?

I've got the new MacBook. So, I'm gonna be short on space if I allocate space from the in built Hard Disk or ssd whatever you want to call it..
Is it in any way possible to set up the windows account with an external hard drive(with USB 3)? Or can I use time capsule(or whatever their external hard disk is called) as an external drive for windows?
Since I'll mostly be playing games in windows, I'll need decent space there too...

I'm not sure you're numbers are quite right. I have Windows 7 Home Premium 32bit installed right now with Service Pack 1 on my bootcamp partition. I've also got Steam and Deus Ex: Human Revolution installed. Steam and the game occupy 8.47GB of space. Total space occupied on the disk is 21.2 GB, which means Windows is taking 12.73 GB. So I'd say the system requirements of 16GB for 32bit and 20GB for 64bit definitely include cache and paging, and also account for service packs and drivers.
You could easily get by with 20GB minimum space for bootcamp.
Take a moment and read the posts on this site, users who installed Windows in a 30G or less partition come here regularly trying to find the easy way to make it larger. We'll help you when you need the space.
Windows 7 should not be installed in less than a 40G partition, larger if the drive is an SSD.

Hi:
You can probably downgrade your Vista notebook to XP, but you don't have a license (downgrade rights) to do that from Microsoft.
Normally, only business notebooks and desktops were given downgrade rights to XP due to the risk of companies operations grinding to a halt because of software incompatiblities with some programs and Vista.
Personally, it would be better anyway to move on up to Windows 7.
Since your notebook came with Vista, it can run Windows 7. For any missing drivers you may have you can normally use the Vista drivers on your notebook's support and driver page.
Additionally, you may want to read through this dv2000 upgrade guide for Windows 7.

Can i use my external drive for TM and files i don't want on my mac HD

my hard drive has a total of 232.57g which is not nearly enough space to save all my pictures, movies, etc. i've been using a 300g external drive to save my pictures, movies, etc. which is now full so i bought a maxtor one touch 4 750g to hopefully back up my computer using time machine, my 300g external drive, and whatever new pictures, movies, etc.
if i set up my new external drive for time machine can i still put the pictures, movies from my 300g external drive and whatever new pictures, movies, etc. on my new 750g external drive?
do i need to make a partition? if so can you tell me how?
should i not use time machine?
any information is appreciated

mac HD
capacity: 232.57g
available: 170.29g
iomega
capacity: 298.02g
available: 14.29g
one touch 4
capacity: 698.51g
available: 698.36g
thanks for the quick reply but i need to explain it better or ask, once all is backed up from my mac HD and my iomega external drive to my new one touch 4 i want to stop using the iomega since there isn't much room left on it
will i be able to add files directly to the one touch 4 without having those files saved to my mac HD like i do now?
or will TM remove my files the next time it backs up my mac HD since i won't have the iomega on anymore?

Can I use new install disks for older computer?

I have a new MBP (which I'm very excited about!). I am going to pass my two-year old MBP to one of my college kids. I would like to wipe it clean as he will be transferring all of his own info onto it from his current MBP (which will then be passed down to another college kid). I can't find the original install disk. Can I use the ones that came with the new machine?

No. The install disks are specific to the model they ship with.
I've read that a Retail copy of Snow Leopard will allow you to essentially do a 'fresh' install of the OS, but it does not include the diagnostics and configuration features of your original system disks.
You can call Apple and order a replacement set of disks for a nominal charge (around $40, I think I've read.) Since you're keeping it in the family, that would be an important thing to have with the Mac in case you cannot locate the originals.

Can I use same recovery disk for two identical computers?

I own two PCs, model m8034n, which were identical when I bought them. If I order a Windows Vista recovery disk for one of them (specifying the serial number when I order), will I be able to use it to restore the other computer to its factory condition?

I imagine as long as the Vista versions are the same on both computers it would be OK to use it. No guarantee it will work but you may try.
Please mark my post as SOLVED if it has resolved your problem. It helps others with similar situations.

Can I use an external battery pack on my 17" Mac Book Pro?

Hi
This may sound like a crazy question, but is it possible to safely use an external battery pack on my Mac Book Pro?.....specifically a Bescor Video Light battery pack which I can just plug my a/c power cable into. This would be very useful in the case of a local power failure (which actually may just happen tonight, as we are currently in the middle of a blizzard).
Just wondering......
Thanks,
Anneita

Yes, you can use external battery packs — but I wouldn't use one that I wasn't perfectly certain was very carefully controlled.
External battery packs specifically designed for MBPs:

Another option, designed to protect sensitive equipment from power surges and enable uninterrupted computer usage during AC power outages and irregularities, is called an +uninterruptible power supply,+ and the leading manufacturer of such devices — which incorporate storage batteries of various capacities — is APC:

How can I use my external hard drive from PC to Mac without reformatting???

Ok, so I am computer illiterate. I have always used PC's and have just bought a MacBook. When I plug in my external hard drive into my new Mac, it says it needs to be reformatted to use with Mac, which would cause all data to be erased. Is there anyway to get around this?
Please help me!

OK... as Woggledog indicated, OS X cannot write to NTFS formatted drives. NTFS is a proprietary Microsoft format. Conversely, Windows can neither read nor write to an OS X formatted drive.
Both Windows and OS X can read and write to FAT32 (this is a fairly old format). The down side to FAT32 is that the largest file you can work with is 4GB. That is probably fine for most people... but if you're working with large files (videos, virtual drive images, large backup files, etc...) FAT32 is not suitable. There are applications that you can purchase for both Macs and Windows machines that will allow them to read and write to the other format.
An immediate option provided you have the space on either your PC or Mac is to create a folder on either machine and move everything from your external drive into that folder. Then you can format the drive to FAT32 and then copy everything back over to the external drive (and delete it from your Mac or PC's internal drive). It might take some time depending on how much data you have... but you'll only have to do it once... and this is assuming you have enough space on one of you machines to copy the data from your external drive.

I have a late-2008 macbook that is running 10.5.8. I also have a newer macbook that came with snow leopard. Can I use the install disk that came with the newer macbook to update my older macbook?

Also, when upgrading from Leopard to Snow Leopard, will I lose all the data that is currently on my hard drive?

No, that SL disk is meant for the computer it came with only.
Upgrading to SL generally will not cause data loss, but you should have a backup of your important files in any case.
You can get a Snow Leopard disk by calling Apple - in the USA it's 800-MY-APPLE.
Best of luck.

HT1918 how can i use a itunes card for payment with netflix?

how can i use itunes card for payment for netflix?

Sorry guy, but I think you are out of luck on that one- maybe someday if Apple gets Netflix under an exclusive contract.. But for now Netflix is its own entity, therefore your account with Netflix is not affiliated with your iTunes account and you have to subscribe and pay for Netflix via credit or debit card.

I am getting a message that my startup disk is full, what files can be safely removed to open up space or can I use an external HD for my startup disk?

Converted a FCP X movie into a quicktime .mov file and tried to burn to DVD, message came up that I needed 26.8 GB to burn this movie. I am not sure how I used so much memory. I was not creating Blu-ray movie just a standard DVD. Anyone have any suggestions for what I did to creat such a large file?

It needs free unfragmented space on your boot drive.
So just what and how large and how full is it?
And it isn't 'memory' (ie, RAM), storage is never referred to as memory.
Your system is likely running something later than the 10.6.6 shown.
Clone your system to another hard drive adn then try, or clean it up after backing up with CCC
While at it, move all your home data and media folders off the boot drive (leave a mini ~/Library only)
System
Media and data folders and libraries
scratch
projects
backup partition(s)
etc
more efficient and runs better.
never let the system drive get to less than 30% free, even more.

Can I use an external drive for Time Machine and storing other data?

At the moment I have one external drive, a 500gb LaCie. My internal drive is 160gb. I don't think I'll be using all 500 of those gigabytes for a while, so I want to put them to good use. Can I make a partition on this drive and use that for Time Machine, leaving the rest of the drive for my documents and other files? If so, how would I partition the drive? I'm not fluent in Disk Utility and even though I'm pretty sure I know how to do it, I don't want to screw up. Also, how big a partition would you recommend?
While we're here, I have a second question, somewhat relevant to the first. Could I move my Time Machine backups to a second drive if I wanted to? Also, if I used a big drive (say 1tb) could I use Time Machine to backup my current LaCie to a partition on that drive? Thanks in advance.

Does that also mean that I could back them both up on a very big drive?
Yes. Time Machine will, by default, back up all of your external drives unless you specifically exclude them.
Also, will Time Machine backups eat all my space after a lot of usage?
It depends on what you do on your Mac. If you work often with very large files (video editing, heavy photo editing, big disk images, Microsoft Entourage data file, Parallels disk image file, etc) then your backup drive could fill up very quickly.
I use my Mac mostly for e-mail, web browsing, iTunes, iPhoto, and the occasional iMovie project. I have 92 GB on my main hard drive (60 GB of which are my iTunes and iPhoto libraries, and one iMovie project.) My Time Machine backups consume 155GB on my backup drive, and that's after using Time Machine for a full year.
