Dear Aunt TUAW: Help me read data from my nano
Dear Aunt TUAW, Greetings from overseas from the long-lost branch of Dutch family members and thanks for al. your helpful posts. My question is the following. I have an iPod nano (sixth generation) which I use quite often as a flash drive. The problem is that I can not use it on a Windows PC since I have set it up initially with my Mac. Is there any way to make this work since quite a lot of people around me (still) use Windows PCs? Your loving nephew, Ivo Dear Ivo, The Windows-OS X file system divide is one of long standing. Unfortunately, the last time Auntie dealt with this problem herself was a badjillion years ago, back when MacOpener was still relevant. So take that in mind as she dishes out advice from the age of the dinosaurs. Your nano is normally formatted using Apple's HFS+ file system. A utility like MediaFour's MacDrive or Paragon's HFS for Windows may solve the problem for you. According to their marketing text, they allow you to mount, read, and write OS X formats from Windows. Each costs US$20 but both utilities offer a free trial, so you can make sure your nano is readable on your Win PC before putting down your money. Hugs, Auntie T.
SanDisk announces ExtremeFFS for "100 times faster" SSD write speeds
SSDs will apparently get a serious (extreme, if you will) upgrade in the coming year, with SanDisk's announcement of a new technology dubbed ExtremeFFS (Flash File System). It is, as you can possibly guess, a new file system, but it'll use page-based methods so that the data's location on the drive won't be tied to its physical space, as it is now. SanDisk says this means that random write speeds are going to be 100 times faster than they are on drives using current technology. The company hopes that this advance, coupled with other upcoming standards, will lead to widespread adoption of SSDs in PCs (and much, much more money in their pockets). That should fit in nicely with news we just heard that Microsoft's Windows 7, unlike Vista, will include optimization for use with the drives. While actual drives that carry ExtremeFFS have yet to be announced, SanDisk expects them to ship in 2009. Fun times.[Via Electronista, CNET]
Leopard does / does not use ZFS, part III: it does! (kinda)
Hopefully this is the last time we'll be forced to post on this topic, but we're not holding our breath: now InformationWeek -- which quoted an Apple executive this morning stating the polar opposite -- is reporting that Sun's ZFS file system IS in fact included in Leopard, albeit with a number of huge caveats. According to a company spokesperson seeking to clear up Brian Croll's "misstatement," while HFS+ continues to be the primary system used in OS X, ZFS has been coded in as a latent, "read-only option available from the command line." An IW reader claims to have accessed the system through Disk Utility's Erase menu, and states that "ZFS is only available on non-boot drives on Sun systems, so this is also the case for Leopard" -- seemingly reinforcing Croll's later assertion that Apple is really only "exploring it as a file system option for high-end storage systems with really large storage." So there you have it: Sun's Jonathan Schwartz wasn't pulling our leg after all, even if ZFS fanboys won't be pleased with the (presumably) final word on this.
Apple: no ZFS for Leopard
Much to the dismay of those Macheads who've started hitting size limits in Tiger's HFS+ file system (all ten of you), Apple has confirmed to InformationWeek that Leopard will not in fact adopt the more capacious ZFS alternative as promised last week by Sun CEO Jonathan Schwartz. Senior director of product marketing for the Mac OS Brian Croll told IW point blank that "ZFS is not happening," contradicting Schwartz's assertion that his company's 128-bit file system would be bringing goodies like built-in data integrity and virtual storage to the iMac and friends. Meanwhile, Sun had no comment on the matter. Of course for most users creating an average Word or Photoshop document, this reversal really doesn't mean much, and may in fact be beneficial when we consider the higher processing demands made by the so-called 'Zettabyte File System." For changes in Leopard that are actually, like, real, you can check out our roundup of the new features right here.
