  • Disconnected Use(with external drive)= Corrupted file structure

    Help. Really like the way LR handles RAW. Big problem for me is that my Mac Book Pro HD is too full. I'm using an EHD from OWC(FW800). If I launch LR with the drive unmounted LR starts verifying files and pulling all sorts of garbage into the LR Folder panel. If I reconnect the drive there is no repair and only a fraction of the files show up with their terminal folder- the folder structure on the EHD is flattened to useless. Fatal flaw? or my error?
    Thanks,
    Steve

    Hi Dan- Happy to try and help. It has happen under 2 scenarios, the lrdb files are at MacHD/users/srp/pictures/LightRoom/...irdb in both cases.
    Scenario 1: I had a folder with some duplicates in MAC HD/users/...pictures/My Photos/duplicate files. When I would dismount the EHD and launch LR it would pull the dups on the Mac HD into the DB and reference what looked to be temps for missing files as well with fairly random preview distribution. The EHD file structure is OWC/users/srp/pictures/My Photos/files by date.
    Scenario 2: I ditched the duplicate folders on the MAC HD (they were not referenced in LR before disconnect anyway) and launched LR. It initiates checking for files and photos again and pulled random preview references to odd files replacing the original folder structure. In this case there were no valid references to pull so it was mostly garbage, it did preserve a few "?" files.
    Folders Panels: http://aktlr.smugmug.com/gallery/2668872#141260988.
    Ive included scenario 1 & 2 grabs and an example of a garbage path
    My work around is that I delete the lrdb and replace it with a clean copy, better than re-importing everything.

  • Use with external drives

    I am yet to use Time Machine, but I wondered if it is able to back up not only from my Mac's internal hard dive, but can I back up from external hard drive to another external hard drive? Or is it only usable with the Macs internal drive?
    Thanks

    Yes, TM will, by default, back-up not only your internal HD, but any directly-attached HD/partition it can read, unless you specifically tell it not to, via TM Preferences > Options.
    Note that, as a general rule, your TM drive/partition should be 2 to 3 times the size of what it's backing-up, to allow it to keep a reasonable amount of old backups.

  • Best Practice for using with external HD

    Greetings, I currently have a fairly large Aperture library, about 210Gb, it's managed by Aperture and on my internal MacBook Pro hard drive.  Not good, I know.  I just received my new MBP with Thunderbolt and also purchased the new Promise Pegasus 12 TB RAID storage device.  My question to the community is this... what is the best way to set up Aperture to take advantage of the external RAID storage while still being able to keep some photos on my hard drive so I can work when away from the Pegasus device.
    Any thoughts are appreciated.

  • Laptop options for use with PrE 11 (£500 ish)

    Hello,
    I'm currently looking to buy a laptop that will allow me to edit various video projects on the move using Premiere Elements 11 (may upgrade at some point). This will serve as my main editing device until I upgrade my desktop, then serve as a portable editing station as I will be at uni next year as well as traveling a lot this year. I do a mix of animation and live action short film work using 1080p footage from my Canon 600D. I am currently looking at the £500 mark, I know it's tough to get a good editing laptop at that price, but I'd rather not spend much more. Currently I have found 3 options, and was wondering if anyone had any advice. The aspects of each laptop I am concerned about are highlighted in red

  • I have an external hard drive that was formatted by a PC and has files and directories etc. I want to format it and use it on my IMAC for backup but I can't seem to write to it nor can I delete current content. How do I initialize it for use with the MAC?

    I have an external hard drive that was formatted by a PC and has files and directories copied to it etc. I want to use it on my IMAC for backup. I see it on my my IMAC . I can open files etc.  But I can't seem to write to it nor can I delete current content. I don't care if I lose current content. How do I initialize it for use with the MAC?

    You can't write to it because it's formatted as NTFS which OS X will read but not write to. If you want to continue using the drive with both a PC and OS X you will need to download and install NTFS-3G so you can then write to it from your Mac. You can get NTFS-3G at:
    http://www.macupdate.com/app/mac/24481/ntfs-3g
    If you want to use the drive exclusively with your Mac then move the data off it and reformat it in Disk Utility (Applications - Utilities - Disk Utilities) as Mac OS Extended (Journaled.)

  • Partitioning an External 320gb drive for use with Time Machine and...

    I want to be able to use my Western Digital 320GB external drive for use with Time Machine and to use as extra storage space on both my Mac and when I boot into Windows Vista.
    Is this possible?
    I was playing around in Disk Utility and would I partition the part I want to use for Time Machine with the Mac OS Journaled, and whatever I want as space for windows, use a MS - DOS format?
    Has anyone done this before?
    Cheers-

    Unless you are using 64 bit version of MSWindows (64 bit XP/Vista), it won't be able to handle a disk with GUID partition table (GPT). Disks with Apple Partition Map (APM) or GUID partition table are the only ones that Time Machine will work with (not MBR disks). Note also that the MBR/APM/GPT are at the DISK level and not the partition level, so don't mix the format with partitioning scheme. Time Machine disks are meant to live in the Mac universe (for now, anyway) and sharing with the MSWindows 32-bit universe is not possible.

  • Compatible External DVD/CD Drives for use with MacBook Air

    Hello all,
    I'm after buying an external drive and was hoping we could put together a list of compatible drives as I've read on other forums that not all are compatible.
    Please no links as they tend to expire but rather just list the make and model of the drives.
    Thanks,

  • External Hard Drive for PowerMac G5 for use with FCP Studio

    Hello,
    I'd greatly appreciate any recommendation for an external hard drive for a PowerMac G5 for use with FCP Studio.
    Thanks.

    We see alot of Lacie issues here and elsewhere.
    Drives fail... period. I believe you hear more about Lacie drives failing because they sell a ton more of them than many other suppliers. I've got 8 of em sitting right here on the desk and two more at the second station. I've lost one since I started using them years ago (and it had problems right out of the box) and I use them pretty heavy.
    I understand that they use several different brands of drives in their enclosures, but from my experience they must have pretty good QC standards for what they package.
    The guy said the G Techs were a little overkill for his needs. Lacie doesn't pay me. But if someone asks "how are Lacies?" I'll tell them they've been great for me and many others I know, especially if your requirements are capturing DV.
    In five years, I ain't heard anybody say anything about it.
    As for FCP. I love it! In 20 years of business, it's probably the purchase that's given me the most bang for my buck. But if you haven't heard people knock it, you've never met an Avid zelot, bruhhhhh, just the thought gives me shivers.
    The drives X mentioned are designed for video work.
    What Studio said, well he gives out some of the best advice on this board
    (and maybe the most! ) and my reply to his post... that's why I used the little smiley face. No offence intended X.
    I only meant to say that, in a world where software like FCP can do what it does at the price it does it, and drives like Lacie and G Tech can give you the storage they do for the price they do, the line between consumer and professional products is easily blurred.

  • I'm having a problem with using an external drive for my iTunes media

    I recently switched to using an external drive for my iTunes library and I was able to switch everything fine. I was able to get iTunes to download and new TV shows, videos, and music that I purchased from the iTunes store to the iTunes folder on my external drive but I can't get it to do the same for applications. All my applications are still being used through the iTunes folder on my internal drive and new ones that I download get put in that folder too. How can I set it to get iTunes to put new applications and use the existing application files from my external drive?

    There is a Windows based utility that will allow one to change the location of the 'My Music' folder, but you appear to be running a Mac.
    You may find more appropriate help in the iTunes for Mac Discussions.
    If you are running Windows, post back and some info can be provided.
    Best of Luck

  • Convert IDE 2.5" external enclosure for use with SATA hard drive

    Hello all,
    I recently upgraded my Macbook hard drive and ordered a 2.5" enclosure at the same time for use with my old hard drive (http://www.newegg.com/Product/Product.aspx?Item=N82E16817347007). As soon as I opened it, I noticed that the pins don't line up and have now learned about IDE vs SATA in the forums. Okay, is there anyway I can still use this enclosure? An adapter?

  • How do I use an external drive with iTunes

    I want to use an external drive (Windows XP & USB) for My Music Library. iTunes is running on the 'C' drive and points to the external drive. When I 'add folders' the music is available and plays, but I don't have my playlists or the play count / last played data. I have copied the 2 iTunes Library files into the exact same location on the external drive (My Music\iTunes). Either iTunes or Windows moves these files to the 'C' drive My Music\iTunes folder, and I don't have problem with these files on the 'C' drive as long as the music/video files reside on the external drive. I would like to set this up so the external drive looks and responds just like if the library was on the 'C' drive.
    Can someone help me get this right so it works?
    Thank you very much

    Can you afford a new Thunderbolt case and cable? any case with FW800 is going to be slow 72MB/sec and less, and any new 1TB drive is capable of 75MB/s minimum up to 125MB/sec.
    Thunderbolt storage can of course when setup properly reach 100's of MB higher using multiple drives.
    Use what you have for a system backup or for secondary backup storage.
    you might be able to take the drive - most cases allow you to open and swap drives - and use this:

  • Using an external drive with shared files (iPhoto, iTunes), attached to a Time Capsule, can the contents of the external drive be backed-up to the internal Time Capsule drive? Perhaps a RAID1 mirror to a partition?

    Using an external drive with shared files (iPhoto, iTunes), attached to a Time Capsule, can the contents of the external drive be backed-up to the internal Time Capsule drive? Perhaps a RAID1 mirror to a partitioned Time Capsule? I understand that the Time Machine (software) cannot backup a networked drive (the external) and that Time Capsule (the router/wireless hard drive) does not have its own backup software... so it won't backup the connected drive. What I would like is an alternate solution for having an automated backup of a networked drive. A 2TB Time Capsule has more than enough space for Time Machine backups of my family of Macbooks, so I had hoped to mirror a 500GB external drive (with shared media files) to a portion of the Time Capsule internal hard drive. I assume this would require a partition of the Time Capsule drive. If not, would the sparse file from the various computers being backed up need to be copied to the external drive as part of the RAID1 setup? This seems like overkill for the Time Machine backup, but it would cover the media files.  

    The complexity with this idea is the software has to run from a Mac computer on your network.. so you need a Mac turned on, probably most of the day.
    It isn't possible to partition the TC although you can create a image area.
    The software would have to copy the material, that means all files to be copied, go from USB drive, back to the Mac, then back to the TC, and written to the drive. In other words you have just added Network congestion, although a proper incremental backup type software will not actually use a lot of capacity.
    Finally it will be slow.. network drives are slower than internal drives. Well USB connected drive is much slower than the same drive connected directly to the computer.. and if the drive is connected directly to a computer it can be shared with the network.
    http://www.anandtech.com/show/4577/airport-extreme-5th-gen-and-time-capsule-4th- gen-review-faster-wifi-/4
    Read carefully the speed of the USB drive plugged into the TC.
