Raid 1+0, which 2 hard drives?

On raid 1+0 with 4 drives, if they are on bay 1, 2, 3, and 4, is there any way to find which two drives are mirrored and which ones are striping? thank you.

It's usually the iPhone that dominates Apple's earnings reports but let's not forget about the iPad: if new reports out of Asia are to be believed we might get three new fruit-flavoured slates before Christmas.The leaked tips centre around the iPad mini 4, which sources say will be a shrunken iPad Air 2, complete with an A8 processor and an 8MP iSight camera. The dimensions will be the same as the iPad mini 3 except for the thickness, dropping to 6.1mm from 7.5mm.You may remember the rather underwhelming launch of the iPad mini 3, where Apple added Touch ID and very little else. This time around the upgrade looks much more substantial.Three's a crowdThe report also mentions the iPad Pro, the super-sized iPad that Apple has been rumoured to be building for several years. Apparently it will come out alongside the iPad Air 3 and the iPad...

Which external hard drive should I use/choose as I am setting up Time Machine on my MacBook Pro 15 for the very first time?

Any of these SATA HDDs that are at least the same size as your internal HDD (preferably larger capacity). In addition you will need an enclosure, preferably one with a Firewire as well as a USB connection.

Which external hard drive should I use to save my iTunes library?

Hi,
So I have collected so much music and movies in iTunes that my internal HD is practically full. (Library is over 500GB of 1TB and the rest is taken up with my apps and programs.) It's time to purchase an external hard drive to transfer my library to. Furthermore, I currently have a 2TB WD My Book for Mac that I am currently using for backup. The My Book is also full and Time Machine is deleting the oldest backups to make room for the current ones.
Here is where I need everyones advice. I am planning on purchasing a 3TB WD My Book for Mac. I am planning on purchasing more movies for iTunes. Which external hard drive should I use for what? Option A or B
Option A: Put my iTunes library on the 2TB external hard drive and use the 3TB for backup
Option B: Put my iTunes library on the 3TB external hard drive and continue to use the 2TB for backup
Also please give me your reasoning.
Thanks everyone for your responses!

Limnos,
So, let's go one step further with this. I read your reply to moving iTunes library to an external hard drive: https://discussions.apple.com/thread/4594518?tstart=0 However, if I move the iTunes library, will this include all the movies and apps that I have purchased?
Thanks!!!!

Which internal Hard Drive for a Mac Pro

Hi there
anyone got any preferences or heard anything negative about,Seagate, Hitachi and Western 500GB Hard Drives to fit in a Mac Pro ? Or is there another make I should be looking at ?
Just about to upgrade and Apple prices are silly.
Thanks

Western Digital strongly recommends not using the RE2 for non-RAID desktops for a reason. It's not that you can't use it for a non-RAID, but only if your data safety isn't a major concern to you.
This is one of their warnings in their own words:
"It is important to realize TLER-capable hard drives should not be used in non-RAID environments."
Digging a little deeper into WDC's website they give the reason:
"Western Digital manufactures desktop edition hard drives and RAID Edition hard drives. Each type of hard drive is designed to work specifically in either a desktop computer environment or on RAID controller...
"When an error is found on a desktop edition hard drive, the drive will enter into a deep recovery cycle to attempt to repair the error, recover the data from the problematic area, and then reallocate a dedicated area to replace the problematic area. This process can take up to 2 minutes depending on the severity of the issue. Most RAID controllers allow a very short amount of time for a hard drive to recover from an error. If a hard drive takes too long to complete this process, the drive will be dropped from the RAID array. Most RAID controllers allow from 7 to 15 seconds for error recovery before dropping a hard drive from an array. Western Digital does not recommend installing desktop edition hard drives in an enterprise environment (on a RAID controller).
"Western Digital RAID edition hard drives have a feature called TLER (Time Limited Error Recovery) which stops the hard drive from entering into a deep recovery cycle. The hard drive will only spend 7 seconds to attempt to recover. This means that the hard drive will not be dropped from a RAID array.
"If you install a RAID edition hard drive in a desktop computer, the computer system may report more errors than a normal desktop hard drive (due to the TLER feature). Western Digital does not recommend installing RAID edition hard drives into a desktop computer environment."
Of course when they are speaking of desktop hard drives here, they mean it in the context of non-RAID. Elsewhere on their site they recommend the RE2 for desktops but only in the context of a RAID system.

How do I set up a RAID array with an external hard drive?

Im trying to backup my hard drive onto a 250 GB external hard drive (connected by Firewire) via a RAID 1 configuration. What is the best way to do this?
MacBook Mac OS X (10.4.6) Intel-based, Windows XP Pro is installed via Boot Camp

There are times when a mirror is fine. SoftRAID in their example of uses, has a situation with someone who doesn't backup, has a laptop (where failures seem higher) and might also want to be able to take the external mirror and take it with them.
One backup is never enough. What if something goes wrong during the backup? power failure or crash? the backup is now corrupt.
Having a mirror and a 2nd copy would be fine. And you can do that. I find DVDs have been too small and slow in the past to use regularly, I use disks, and burn a DVD of important stuff on a 3 month or longer basis, and some stuff is even less.
so while there is always going to be "mirror raid is not a true backup mantra" it is still useful for what it does. Even if it is instant and copies the good and bad. Just don't rely on it as your ONLY backup, you should have another disk drive as well (and DVDs).
Also, FW400 is not a speed daemon - 35MB/sec or less is not uncommon.

Which external hard drive do i need to transfer my files from my G4 with OS 10.3 to my new iMac?

I have a Mac G4 PowerPC (with: processor speed of 1GHz, 1 MB L3 cache) running OS 10.3.9. I want to transfer my files from the G4 to my iMac (.21.5/2.5QC/2X2GB/500GB/6750M) which is still in the box, for the last 3 years. I believe it is running OS Mountain Lion. All the Mac-compatible external Hard drives i have looked at are for OS 10.5 or 10.7 and above. Are there any external hard drives for sale that will work with my OS 10.3.9 to transfer files to my iMac? If not, how can i do this transfer of files?

An external hard disk drive enclosure with FireWire400/800 ports, with others
may be able to be used; but not as an adapter from one kind of port to another.
The old iMac uses USB, perhaps as slow as 1.1; that won't work with newer
USB3.0; but both the newer and older computers could use FireWire; or maybe
ethernet for computer to computer.
Newest models have Thunderbolt data ports, so adapter cables are needed.
And then you'll need cables to match whatever combination you end up with.
{You may have tried something or another, but not posted back to say if you did.
And this thread is nearly two weeks old, now. I just happened to find it here.}
For what you suggest, you may be able to find a suitable cable, perhaps FireWire
or Ethernet, depending on the ports available and cables still applicable to both.
Does newer iMac have FireWire ports? You could buy a FW400 to FW800 cable where
the ends are different, if the newer machine has FireWire800. [The old one has FW400.]
This would have to be equipped with the protruding connectors so each could make
the connection between each computer's built-in ports. Not all cable sets do this.
This would be the fastest way to copy content between machines, if FW 800 in newer mac.
Port-powered external hard drives may be under-powered and fail to work, so that is why
I suggest enclosed HDD with its own AC power adapter that will not rely on FW or USB
for the power to run the drive and the electronics inside the enclosure.
example of external enclosures with multiple ports and its own power adapter:
http://eshop.macsales.com/shop/firewire/1394/USB/EliteAL/eSATA_FW800_FW400_USB
This is an image of the lesser model series with fewer ports. The FW800 and USB3.0
are both backward compatible to their older counterparts, FW400 & USB2.0. But even
so the old 1GHz iMac G4 with USB1.1, would not be able to use newer USB3.0; yet
should be able to connect via FireWire400 to FireWire800 by special cable.
If the iMac G4 is still working, that's a plus. Attempting to remove the old IDE/ATA HDD
and access it outside the PowerPC iMacG4, is really a troublesome effort, one to avoid.
But the PPC iMacG4 can be started in Target Disk Mode and accessed as a hard drive
via FireWire cable, too. Then files can be seen as though the old Mac is an external HD.
In any event...
Good luck & happy computing!

A mackbook, a pc laptop, and... which external hard drive???

I have two laptops; one is a Mac and the other a PC. My wife and I have a good collection of music together, but each of us has our own iPods and playlists. Therefore, with my modest knowledge I thought it would be a good idea to have an external shared drive where we could store all our files and access them from either or both laptops. The idea is to use that external hard drive wirelessly as you would use an internal one, in each of the laptops.
My question is, is this possible? If so, which one would you recommend?
We are looking into buying something with 500GB. I was especially interested in a Western Digital, but I have read so many bad reviews, and - as you could probably tell by now - I am not enlightened with computer knowledge. I have also recently read some review of a LaCie2 500GB and it is winning my vote. The thing is that I do not want to buy something that is not going to work the way I want it to with both computers simultaneously... any ideas?
I appreciate all the help!

Ok. So what i have done is installed Itunes on my laptops C drive. I then go to 'options' and 'add folder' where i select my music folder that is then stored on my external hard drive. It then takes say, half an hour to copy across the titles of the music. I can play them fine at this point. Now what? Can I turn the laptop off and it'll be fine? Is what I have done so far ok?

Which Backup Hard Drive for Time Machine?

I ordered a new iMac from Apple. I need to order my backup hard drive and someone from here on the boards recommended http://eshop.macsales.com/shop/firewire/1394/USB/EliteAL/400+USB2/. I was going to get the 750 GB backup drive (I got the iMac with 640 GB), but I see there's a 1,000 GB backup drive that's basically the same price ($2 cheaper) but has half the cache (16 MB vs. 32 MB). I'm guessing that the cache stores information as it transfers from the main hard drive before the backup records it, so that the bigger the cache, the more it can store, and probably the faster the backup goes from the perspective of the main computer (i.e. the backup slows the computer less). Do you think that having twice the size of cache outweighs have 3/4 the size of hard drive? Would you go for the 750 GB with 32 MB cache, or the 1000 GB with 16 MG cache?

The only one I really care about is AOL 10.3.7. It allows me to store emails, as emails, in any folder on my hard drive. The newer versions of AOL, called AOL Desktop (which are still in beta as AOL ignored Macs for about 5 years), do not allow you to access files on the hard drive other than files within the application itself. So if I can't use AOL 10.3.7 I'll lose 15 years of email. Right now I forward all my email from the two colleges where I teach to AOL and used 10.3.7 to download them to my hard drive. That way when a student writes about an issue I can look back at her previous emails and see both what she and I said. (Or when some administrator promises something, I go back and read what he actually said at he time. :-D) I routinely look back at older email, especially for work. So it's very important that I be able to continue to access my older email files, and store new emails on my hard drive in my current file hierarchy. I mean Office and other applications allow you to store what you want where you want, so I don't see why email programs no longer do.
As for the rest, I do want to keep all my Safari and Firefox settings, but as I'm using the current versions, there's not problem with them. I'd prefer not to have to take the time to reinstall everything of course. As for Office, I am using 2004 for Mac, but I've ordered 2008 for the Mac with my iMac because Apple and Microsoft have a 50% off deal for back to school, which cuts about another $35 off the usual 40% educational discount that Microsoft offers. (Apple used to offer those big discounts too, back in the 1990s, when I got my G4, but these days they offer only $50 or $100 off as an educational discount, which is one reason I haven't bought a new computer in 9-10 years!) I have the latest Acrobat too, as Adobe also had a good educational discount.
A buddy of mine who does programming for the federal government said that it's a real testament to Apple's quality that my 10-year-old G4 still performs. He said that a PC would have died about half way through. I did get the top-of-the-line model thanks to both the educational discounts of the day and to the Apple student loan program (I was in my first Ph.D. program then), and expanded the RAM, so that 10 years later I'm still able to use the G4. I do all my teaching at two colleges online now, and the computer has gradually gotten slower as it encounters more and more information it was never designed to handle. Ten years ago every website didn't have fifty dancing babies or whatever. Now every website seem to have an embedded video or three all insisting on playing at the same time. I'm looking forward to that sort of thing not bringing my computer to a halt.

Which external hard drive snow leopard

Which BRAND of pocket 1,5-2TB hard drive should I buy that I can partition down to have one 80GB clone of my Macintosh HD? Apparently NOT Toshiba...

Thanks Dirk,
Tried your suggestion various ways but it had no effect the download button was still greyed out and the install button would not activate will keep trying to find a solution. I dont want to boot from the external hard drive that has Lion on mainly because it is a usb HD and the connection to my wireless modem slows the connection rate and downloading would take about ten hours

Which external hard drive is best for the MacBook Pro? Can I use the SuperDrive?

I am looking to buy a new external hard drive for my new MacBook Pro and just want the best one for this laptop. Can i use the SuperDrive? It looks like the SuperDrive is for the MacBook Air but wasn't sure if it could be used with the Pro as well.

Apple does not make external harddrives, except maybe the TimeCapsule which is Router/HD combo for use with the TimeMachine software.
http://store.apple.com/us/browse/home/shop_mac/mac_accessories/storage
There are many to choose from, and you will I sure get much advise across the board.
I would stay away from WesternDigital.
Othere then that OWC are a dependable supplier.
I am using a 1TB/QuadInterface/DiskGo/ by Edge they had a very sweet back to school discount promo.
Look around for your "sleek and thin in design" and a good deal as they all go on sale periodicly.
Think along the lines of USB 3, Thunderbolt if your machine supports it or at a minimum FireWire800.

Which External Hard Drive Should I buy?

What brand of external hard drives for the macbook do you guys recommend? Where should I buy it from?
I will be using it to boot from, so I want something fast. As for size, 250+ GB is plenty. I am more interested in how fast I can run OS X on it.
Thanks,
KANE

Depending on what interface you want, you have a variety of choices from Other World Computing. I bought one of the basic OWC Neptune FW400 drives mainly for backup, but it is also bootable on my older machine. The newer Intel machines can boot via USB 2, so that might be a good faster option for your MacBook, but they have some OWC Mercury drives that offer multiple interface options, so you have the flexibility of FW400/800 USB2/1.
http://eshop.macsales.com/item/Other%20World%20Computing/MEU7500G16/

Get two of them, so you can make a regularly scheduled backup, using DejaVu, Retrospect, or CarbonCopyCloner, etc...

Which external hard drive can I use with my Macbook (2009)?

I'm looking to purchase an external hard drive for my 2009 Macbook os x 10.6.8 (the heavier, white laptop). It looks like most hard drives are compatible for Macbook Pro and newer.

If your MB is an early model 2009 you can use either Firewire or USB 2 drives, late model 2009's don't have firewire so you're limited to USB. I'd stay away from WD and Seagate externals, their enclosures aren't very reliable. The Toshiba Canvio drives work well. Pretty much any drive from OWC is top shelf http://eshop.macsales.com

I'm confused...
I know you can reformat the 2nd drive for mac use but will it work with my Time Capsule? or Will the WD Mac edition be the better option? if so what are the advanagtes for have the WD Mac edition over the non WD Mac Hard drive?

As long as you don't use the ExFat or Mac OS X encrypted formats, yes.

Which external Hard Drive?

Hello,
Am wanting to back up my iBook with a separate Hard Drive, in the main for safety reasons. Most of the ones I've seen on the market hold either 2 or 3GB of memory or 200GB+. I mostly use my Mac for iTunes and Photos, and would only need about 50GB maximum.
I travel a lot, so size is of importance, but I only really intend to have it 'just in case'. Also, I am in the UK, and so am looking for hard drives available here and in pounds!
Any recommendations/suggestions would be greatly appreciated...
iBook G4 Mac OS X (10.3.9)

Hi Zachary,
I have recently gone down this route and settled on LaCie's Porche portable USB/Firewire drive. I went for the 80 GB for £109, but they do a 60 GB too for £89. They are very small (about the size of a 50g packet of tobacco but thinner) and light, and come with a 'velvet' pouch. Silverkeeper back up SW is included, and 2 year warrantee. The bad news, LaCie's website is showing them as out of stock at the moment but Amazon, Dabs etc may do them.
Always go for the largest (in terms of GBs) that you can afford, you'd be surprised how quickly you can fill it up. Also, get a firewire drive. You can't boot your iBook from a USB drive.
I have split mine into 3 partitions, a 30 GB clone of the iBook, a 10 GB 'bare bones' installation of Tiger with the remaining <40 GB for miscellaneous backups like movies, downloaded .dmgs etc that aren't needed on the iBook.
Have fun,
Adrian
