Lion reports: NAS issues, creating a clean install

updated 10:30 pm EDT, Fri July 22, 2011

Some iTunes users likely to be inconvenienced

As is traditional with any new and significant update to an operating system, reports and discoveries are being posted throughout the Mac community regarding Lion, the latest version of Mac OS X. One issue in particular that stood out as being quite obscure but potentially important was a post from Online Tech Tips regarding changes for third-party Network Attached Storage (NAS) drive users, along a step-by-step guide on how to do a clean install of Lion from

The site reports that NAS drives, such as HP's Media Smart Server, may not connect properly under Lion unless they already support the latest version (2.2) of Netatalk, an open-source Apple File Protocol (AFP) file server that is used to allow Macs to connect to non-Time Capsule NAS drives for purposes such as Time Machine backups and iTunes or iPhoto library serving. NAS drive manufacturers are slowly releasing updates that fix the issue, but not all manufacturers have caught up yet.

Synology, QNAP, Buffalo and HP MediaSmart Server users all report issues, but all of the mentioned companies report that a fix is coming soon. In the case of QNAP, forum users have posted some possible workarounds until a permanent fix is issued.

As of this writing, Netgear and LaCie have both recently updated their software to support Lion, and users of those products should check the links to download the new version.

About's Tom Nelson has posted a four-page, step-by-step guide to creating a "clean" install of Lion on a connected hard disk, SSD or even thumb drive. Users are cautioned that Lion will create a new, 650MB "recovery boot" partition on installed drives, and that a minimum of 8GB of free space is required. The report also details the procedure for creating a bootable Lion DVD disc if users want to clean-install Lion on the current startup disk.

After first backing up any important data and then erasing the target disk, the report mentions the method by which users can show all eligible disks and change the target from the default (the boot drive) to a different one. The Lion download is normally located in the user's Applications folder on their startup drive.

    My MacBook Air shipped today

    And I will spend however long it takes to get Snow Leopard to run on it. No Lion for me for 6 months, thanks.

    As you probably know ...

    that will be impossible. Macs can't run any version of the OS lower than the one they ship with, and yours is incredibly likely to ship with Lion on it.

    Western Digital

    Time Machine died on my Western Digital 1 TB My Book Live NAS server when I installed Lion. Today (7/22/1) I got an email from them promising "some important software updates" including new features and an "optional firmware update." There's to be an announcement next week, although no shipping date is given. No mention of a fix for Lion problems, but that's perhaps because they didn't want to alarm Windows customers. Those who upgraded to Lion discovered the problem pretty quickly.

    Glad I saw this article. I have a 2Tb WD MyBook that I use for Time Machine backups. I would have been really p***ed if the backups had broken.

    Not new issue for manufacture

    Manufacture have know this issue since the first beta of Lion, months ago because it was reported then, but most ignored it. It was clear that Apple was running an updated version of Netatalk and this was the same for all other beta. There is no reasons why it is taking manufacture so long to update the firmware on the Nas drive.

    Iomega okay, no TM

    No apparent problem connecting to my Iomega StorCenter ix2 and getting at files, but TimeMachine won't recognize it anymore. Between that and several important PPC apps no longer working, I'm starting to regret having done this...
