How to create partions (Leopard 10.5, MacBook)

I just got a new MacBook 13" with a 250Gb HD. I want to create 2 partions, one to keep the OS and the other for data. Is it possible to partion a disk in Leopard without installing everything again? In case I need to re-install the OS again, will the recovery disk be able to install the OS on a partion rather than on the entire disk? and, which soft should I use to partion the disk? and when is this done? at installation time or after?

I'm new to the Mac world and I don't want to mess eberything up 😟

Thanks

Hi you can with Coriolis' €50 iPartition:

This technology is not without its risks so ensure that you backup before you start.

Reinstalling (especially if you customize and, say limit yourself to English only, does not take long and is pretty rock solid, although you'll also have to update the OS after installation.

The Mac is very intuitive - if you were reasonable technical with your previous platform there is no reason why you can't be conversant with your Mac in a few days. There is so much info and help available on the internet.

Whatever you choose - good luck!

Yes, it's possible to partition "on the fly" and it can be done via the OS or with a free utility like iPartition. But it is safer to erase the disk before creating partitions.

I'd advise you to think carefully about how much data you are using now and how much you will be using, then partition accordingly.

Once you create the partitions use a utility like SuperDuper to make a bootable clone of your startup volume. It's free for cloning.

Then, you should never need your install disk again unless you want another fresh install. If you have any major issues with your system just erase it and clone the backup. And if you do want to install to a partition you can do that too.

If I understand correctly what you are saying is similar to what I used to do with Norton Ghost in WinXP. Thanks for the tip.

I have to get used to hearing to hearing the word "Norton" without flying into a rant.

I understand Norton is OK on the Windows side but it should never come in contact with the Mac OS. It mangles them. I've seen so many Macs rendered useless over the years by Symantec tools that I've built up a phobic reaction. If a Norton disk got close to my Mac I would swab the area with alcohol.

I ain't afraid of no ghosts! Except the ones named "Norton" 😉

Yes, you can get just about anything for Windows "for free" but much of it is pirated commercial software & laced with malware. Some of it you get whether you ask for it or not. (Security experts estimate that a PC without up-to-date, effective anti-virus software installed has about a 50/50 chance of being infected _during the first hour_ it is connected to the Internet!)

The effects of PC malware are a very real problem for everyone: for instance, your personal information (including email addresses & personal correspondence of your friends & associates stored on your computer) may be stolen or your PC turned into a "zombie" that as part of a "bot army" is estimated to be the source of as much as 80% of all spam.

Even if nothing that severe occurs, your PC will probably will execute a lot of useless code & become sluggish or unstable, either directly from the effects of malware or from the anti-virus software used to find & remove it. (Amazingly, some PC users even pirate anti-virus software or its updates, not realizing that this is a favorite & highly effective "vector" for infection.)

The numbers are staggering. There are about 50,000 distinct strains of malware "in the wild" that affect PC's. Some experts estimate that at any particular time, the average PC has more than a dozen individual pieces of malware on it in either an active or dormant state, mostly due to the complacency of users who have become so used to the effects of malware & the lure of "free" software that they don't realize their PC's aren't acting normally.

The bottom line is (not too surprisingly) you get what you pay for.

Hi R C-R, funny that you brush on this topic (which is not related to the original post but very interesting indeed). I have used a PC for than 15 years now and I have never EVER used an antivirus soft and I never had a virus on my machine. btw, I use both Win and Linux. So, when eople and 'experts' tell us: "..in less than an hour you PC will die and your data will be stolen unless you buy our product..." remember one thing: they are just trying to sell their prodct and they don't care about your data. Sad but true!.
On the other hand I have to say that Mac is more reliable in that sense mostly because how many people in the world use a Mac compared to a PC? the ratio is pretty small and thereofore the pirate software on the Web is less and the risks are low.

once again, interesting topic to discuss but perhaps we should move it to another forum 🙂

Probably more to the point, Norton anti-virus software or something like it is mandatory for Windows PC's because PC's are the target of so much malware & Windows historically has been so poorly protected against it in its default state.

Mac OS X is not bulletproof but it is very well designed from the ground up to be extremely resistant to malware attacks & Apple is quite diligent about patching vulnerabilities as they are discovered. The end result is that if you allow Software Update to do its thing, you probably don't need to bother with anti-virus software except as a courtesy to the PC-using world (to prevent passing malware ineffective against OS X on to PC users).

I realize PC anti-virus software makers play on fears, but the dangers are quite real & confirmed by independent sources. Overt attacks that try to "kill" your computer are mostly done by "script kitties" that just like to create chaos for its own sake, & are not much of a threat. The real problem is malware that is only effective if the infected PC continues to give the appearance that nothing is wrong.

The motive in most cases is making money, either by selling stolen information or by extortion. Individual users are not usually the direct target, just unwitting pawns in schemes that involve huge numbers of PC's. This is practical only if the individual users are unaware that their PC's have been compromised & the data shows that this happens to hundreds of thousands of them at a time.

If you aren't familiar with the concept of "zombies" or "botnets" this article should be a real eye opener. True, it is a few years old, but it covers the topic pretty well, & nothing has changed -- if anything, the problem is worse than ever, driven by wider use of high speed networks & more powerful computers.
