I am attempting to run Time Machine on my AEBS but when I enter the Time Machine preferences and try to Set Up the HD, my Lacie 1TB HD is not coming up in the menu as an option.

    Check the formatting of the LaCie drive as it must be setup in Mac OS Extended (Journaled) to accept Time Machine backups.

     

    A powered USB hub will likely be required for most drives.....even if they have their own power supply.....because the USB port on the AirPort Exteme is under powered. I happen to have two LaCie drives...and neither one will work with the AirPort Exreme without a powered USB hub.

     

    As you may know, Time Machine Backups to a drive at the USB port are not officially supported by Apple. That may...or may not...be in play here.  Some users seem to be able to make this work while others....like me....have continuous problems when they try this.

     

    If your backups are important to you, you might consider a dual backup strategy in case the backups at the AirPort Exteme port become corrupted.

    Bob,

     

    Thanks for the feedback.

     

    Interestingly enough, from the time I left the last post and when I returned (~30 minutes later), I re-entered Time Machine and my Lacie drive was detected. I am backing up wirelessly as I type this.

     

    Fingers crossed.

    This tells me that the USB port on the AirPort Exteme is really working hard to provide enough power to the hard drive. A $15-20 investment in a powered hub to take the stress off of a borderline power supply in the AEBS might be a good way to protect the $180 that you have in the AEBS.

     

    Your decision, though.

    Bob,

     

    Can you recommend a powered hub to go along with my Lacie drive? And also....will I need to do any type of reconfiguring when hooking up the powered USB hub to the AEBS or is it simply a plug and play ?

    For years, I have used a "no name" Dynex powered hub which is sold by Best Buy and probably other retailers. But, there are dozens of brands available. Just grab one. It's plug and play. Make sure that the hub has a separate power supply. You do not want a "passive" hub.

    Bob,

     

    My initial backup to the the Lacie Drive took 5 hours but all is good (it appears). However, this AM, when I was working on my MacBook Pro, I heard the Time Machine app kick on....i clicked the Time Machine icon and it said the following:

     

    The Backup disk image "/Volumes/TIMEMACHINE-1/PETER TSERONIS' MacBook Pro.sparsebundle" could not be accessed (error -1).

     

    I tried to initiate another backup and got the same error after about 1 minute of the Time Machine app "looking for the Backup Disk".

     

    Thoughts?

    Unfortunately, errors like this may be a preview of things to come if you want to try to continue with the unsupported method of Time Machine backups.

    UGH !

     

    Quick question....do you use Time Machine? If so, what is your configuration?

     

    At the end of the day, my goal is truly to backup pictures and music easily. If Time Machine is not advised, not a problem.

    I use a dual back up strategy.  Time Machine backups from two Macs go to a Time Capsule and each Mac has a drive that is directly connected via FireWire to make a daily "clone" using Carbon Copy Cloner.

    Bob,

     

    Per your earlier post regarding investing in a powered USB hub, my LaCie drive has its own power cord and is plugged into a surge protector.

     

    That being said, do I still need to invest in a powered USB hub?

    Bob,

     

    should I consider returning the AEBS and move up to a Time Capsule?

    I previously stated.....

     

    A powered USB hub will likely be required for most drives.....even if they have their own power supply.....because the USB port on the AirPort Exteme is under powered.

     

    I then stated.....

    If Time Machine backups are important to you, Apple supports backups from Macs to a Time Capsule and also to a hard drive that is connected directly to your Mac via the FireWire or USB connection.

     

    However, the fact that Apple supports these types of setups does not imply that that you will never have any problems.

    Hey Bob,

     

    the Lacie drive that I have hanging off my AEBS has its own power supply. moreover, i plan to buy a non-powered usb hub (4-port) so that I can plug my all-in-one printer into the hub also.

     

    since the printer and Lacie drive have their own power supplies, is it OK if I purchase a non powered hub?

    I recommend that you use a powered USB hub.

     

    If you want to try a non-powered hub, that would be your decision.
