Yes, it's a lot of storage -- but the drive's form factor won't fit into any currently available Mac laptop. (Note the update at the end of this post)

I was pretty excited when the Western Digital news release hit my inbox. The new drives, the industry's first in that size for portables, have pretty good specs and capacious storage space. The problem really is the size. With Apple in the business of providing slim notebooks, the drive is just too tall (12.5mm) to make it into any Apple portable, which maxes out at a drive size of 9.5mm.

The drive will be available in a USB enclosure, and WD is also offering a 750 GB version of the drive as well. The 1 TB drive lists for US$250, while the 750 GB drive is $189. Those prices are for the drive alone. Mounted in a USB enclosure the 1 TB drive sells for $300.

Currently the largest 3rd party drives you can get in current Mac laptops max out at 500 GB.

The Mac Mini may be able to house the new drive, but it would be a pretty tight fit, and according to our Steven Sande, may require the removal of the SuperDrive.

Update: We've had a variety of responses to this post, with different ideas about which, if any laptops could take this new high capacity drive. I thought the quickest and best approach would be to try the experts at Other World Computing, who make a living selling replacement hard drives for Mac Desktops and portables. The tech there told me that the last generation 17" MacBook Pro can take the 12.5mm drive, but that the 15" model can't. He also said none of the unibody MacBook Pro models can take a drive of that size. I'm sure some won't accept this information either, but these were the most expert opinions we could find since Western Digital wasn't sure and Apple doesn't generally comment on such things. Since the drives are just shipping, we'll wait for some real world experience and report back. Thanks to all who commented.

There has been plenty of confusion over the continuing saga of Seagate hard drives with firmware problems that can lead to eventual failure and data loss. We've followed the story here and here.

It hasn't been pretty for either Intel or non-Intel Macs. It would have been nice for Seagate to provide a Mac OS X-native firmware updater for older machines. There must be an awful lot of hard drives out there just waiting to fail. Many people who don't follow tech news don't even know what pain might strike them.

Mac users who had written Seagate about their problems did not get much information, but now there are some more details sent in an email to customers about the bad news for non-Intel based Mac owners. Full email reproduced below:

If you are trying to update your drive firmware with a MAC, you must have an INTEL MAC to allow you to perform this action. If you do not have an INTEL MAC, you will then need to take the drive to a PC, or a MAC with an Intel Processor. If you do not have either, you may need to warranty the drive with Seagate, and the return drive should have the updated firmware upon receipt.

If you have an INTEL MAC, you would simply need to burn the ISO file to CD using the burning utility that you have installed on your system. Once you have the CD created, you will then need to reboot the system with the newly created CD in the CD ROM bay while holding the "C" key on the keyboard to tell the system to boot to the CD rather than the internal hard drive. Once you have booted to the CD, simply follow the onscreen prompts to complete the firmware update. Older Macs that are PowerPC (PowerMac G3,G4,G5, iMac G3,G4,G5) based can not bootup to the FreeDOS. FreeDOS is the operating system that is booted to when booting to the firmware update CD. Please keep in mind that you should always backup the data on the drive before doing the update in case there is data loss. In most cases, the data on the drive should remain in tack and unaltered; however, things happen, and its always better to be prepared in case we come across any obstacles with the integrity of the data on the drive.
Instructions for updating firmware on a Intel based Mac.
1. Download and burn the Firmware ISO that has been provided to you by Seagate for your drive/s
2. Burn the ISO to a CD (how to: http://docs.info.apple.com/article.html?path=Mac/10.5/en/8729.html)
3. Insert the freshly burn CD back in to your Mac.
4. Reboot
5. After the Chime press and hold the Option key on the keyboard.
6. Once you see the Apple with the spinning gear beneath, release the Option Key.
7. At this point the system will come to a screen with pictures of hard drives and a CD, the CD should be named Seagate.
8. Click on the CD
9. Click on the arrow pointing to the right.
10. At this point FreeDOS will boot and the on screen instructions should be followed.
Once again, I want to thank you for your business.. If you still need further assistance, or the information provided was not of good use, please feel free to contact Seagate Technical Support at 800-SEAGATE ( 800-732-4283).

Translation: You are well and truly hosed if you don't have access to a Mac Pro or a Windows PC that can update the firmware. People who have returned their drives to Seagate got a refurbished drive, even if a brand new one was sent in for exchange. Worse, there are some scattered reports that the replacement drive still had the bad firmware! Way to go, Seagate: if your Mac-owning user base didn't feel completely screwed over before this, we all probably feel that way now.

When Steve Jobs announced a ten-fold leap in .Mac storage space, most of us were generally happy to hear it; I know I was. For those of us, including myself, who have been synching their iDisk to use it more or less as an online backup drive however, this good news had an unfortunate side effect in the form of lost local storage space. Because of the way iDisk synching works (a setting you must enable in the .Mac System Preferences pane), the amount of free space on your local hard drive will diminish according to the size of your iDisk. This is because your Mac keeps a disk image that serves as a constant backup of everything in your iDisk - that's part of the advantage of enabling the synching feature because you can retain a copy of everything in your iDisk even when offline, and sync any changes you make once you get connected again.

Before the upgrade, .Mac offered 1GB of total storage between .Mac email and iDisk storage, so synching one's iDisk like this didn't gobble up too much space. Now that this total storage has been raised to 10GB, the tables have turned a bit for us synchers, and especially for me since about a month ago I paid for the next tier of storage (I know - I've been bit by the Apple update bug again); imagine my surprise when my iDisk instantly went from about 1.5GB in size to 19GB.

But how can we solve this problem? There are a few solutions, so you can play with these and see which fits best with the way you work.

The first solution is perhaps the more obvious: log into your .Mac account online, go to your account management page and readjust the balance of storage between .Mac mail and iDisk storage. You can knock your iDisk storage as low as you want and perhaps gradually increase it if your iDisk activity grows in the future. There's room to play there, but you get the idea.

The next solution, the one I originally opted for but have since double-backed on, is to turn synching off. You can still quickly mount your iDisk anytime you need it - assuming you're online - via the Go > iDisk > My iDisk command in the Finder (or cmd-shift-I). If you're mounting it for the first time after a fresh restart or login you'll experience a slight lag, but after that your iDisk should act almost as snappy as it did when you kept it synching. The only problem here, and the reason I'm rethinking this, is the catch with being offline: I'm not offline very often, but when I am, I still need my iDisk, so I just downsized the amount of iDisk storage I have allotted and I'm re-synching as I write this. For those who work differently however, turning off synching is still a viable option: if you're always connected or you simply don't need iDisk files both large and small always available at your fingertips, shutting off synching altogether could solve your storage issues.

The final solution I have is to simply start using your iDisk to store more stuff. After all, with a ton of extra space now you can really let loose and keep a lot more stuff in there, making it online, backed up, sharable by moving to your iDisk's Public folder and accessible via a browser on any web-connected computer in the world. That's a darn handy tool when you think about the possibilities. I'm moving more folders of documents and other files to my iDisk since it is now a pretty spacious and effortless way to store files, share them between Macs that keep my iDisk synched and back them up online all in on fell swoop.

No matter what solution you come up with, I'm not sure how much Apple can do about this considering how the iDisk seems to fundamentally work right now. It sure would be nice if the iDisk could simply expand automatically as you add files to it instead of taking a massive bite out of your hard drive, and who knows, maybe that's something we could see in the upcoming Mac OS X Leopard or beyond. For now, if your iDisk is cramping up your hard drive, it looks like you'll have to get a little creative.

Oh Apple, you sly devil, what with all the secretly upgrading hardware and not even telling us. Thanks to eagle-eyed reader Eric Wortman, we now also found that the Mac Pro gained a RAID card option for those who need mounds of storage and a secure, redundant system with which to manage it. The card supports RAID 0, 1, 5, 0+1, and Enhanced JBOD. The card also features a 256MB cache and a 72 hour battery with which to protect that cache, and it occupies the top PCI Express card slot, connecting to all four internet drive bays.

What's all this RAID connectivity going to cost you? A cool $999 on top of the price of your Mac Pro.

I like a relatively neat Desktop. I keep out just those items I need to access right away for my day-to-day work. It's so easy to clutter Finder, especially when you use multiple hard drives and partitions, an iPod, a memory card reader and the odd CD or DVD. An often-overlooked Finder preference can come to the rescue.

To hide volumes on your Desktop, choose Finder -> Preferences (or just type Command-, when Finder is active). In the General tab, choose which items you want to show on your Desktop. Place a check next items you want to see or clear the checkboxes to hide items. You can always bring hidden items back by updating your preferences later.

And don't forget: whether you hide disks or CDs on your desktop, they're always there on the side drawer of your Finder windows where you'll find all hard drives, servers, removable media and so forth.

Wikidesign tracked down this hard disk drive enclosure which offers you some of very Apple-ish aesthetics. It's a standard 3.5" IDE/(P)ATA enclosure with USB 2.0 and 1394 support. The holes on the back are needed because it's a fan-free enclosure--which you need to take into account because this thing needs good ventilation. The aluminum materials used in the unit should help with heat dissipation but it's probably not very stacking friendly. At £39.99, it's a bit pricey--especially since it doesn't come with an actual disk. You're just buying the enclosure. Still, it's pretty good looking, isn't it? [via WikiDesign]

Lots of news coming out of Macworld, of course, but this one caught my eye: Seagate has announced Mac compatibility with the software for its OneTouch III Mini line of portable USB hard drives. The software offers security (password protection) and standard Backup features -- i.e. schedule backups or utilize the OneTouch button -- but also a great-looking folder-based Sync option: select your Music folder, for instance, on one Mac, back it up on the drive and sync it with the Music folder on another. It's even possible to modify the files on the drive directly, and sync the changes back to your machine.

The drives come in 80GB ($129), 120GB ($169), and 160GB ($229) capacities and are available now. Check out their website for more details, and check TUAW in the near future for a full review.

We aren't sure if this new option appeared today with the newly-updated MacBook Pro, but it's the first time we've heard of it: reader Mark S tipped us off to the availability of a 750GB hard drive option in the iMac 24-inch and the Mac Pro. The massive drive isn't available in any other iMac (they still cap out 500GB), but with 4 available bays in the Mac Pro, they can now be configured with 3 terabytes of storage straight out the gate. That's a lot of iTS movies.

These drives don't come cheap, however: typical of Apple, each 750GB drive (across both machines) is a somewhat expensive $399 upgrade, so that's an extra $1596 just for the bragging rights of having the big bertha of Mac Pros on the block.
