Swapping hard drives .... how does lightroom handle this ?
My photography is done on a separate computer to my online machine and the photo system never goes online ( so virus-proof ).
I use " Laser " brand hard drive racks which allow me to swap hard drives on each machine, and also to swap them between the two computers.
So I have several HDD's with different photo projects on each drive and some backups on HDD's as well.
Lightroom is a database system rather than a browser, so how will it be able to handle swapping HDD's in and out like this ? What happens if lightroom points to a file which is on another HDD not currently installed in the machine ? Will it be able to show all the thumbnails and tell me which HDD holds them ( as I believe programs like Imatch can )? Will lightroom be confused by this. Or will it set up its database on each HDD so each disc is a self-contained library with its own lightroom index ?
I know I can't be the only one with more photos than fit onto just one HDD. Can anyone please tell me how lightroom's library system deals with this situation ?
Thankyou very much for the responses so far ....
I see a potential problem because my HDD's are not permanently connected in the computer. Each HDD as it is swapped in and out is assigned the same identifier, say " drive D " or suchlike by windows. So my drive D might be any one of several HDDs .... with very different content to the previous drive D I had in the machine. If Lightroom stores its library for each of my drive D's on drive D itself, then I suspect there will not be problem because each HDD will be its own self-contained libary and Lightroom which resides on drive C will be able to operate on each one in turn. I will then have a series of HDD's dedicated to specific tasks, and can use Lightroom on all of them.
Windows works this way, where it resides on my drive C and performs operations on each drive D. It has no problem in " picking up " each new drive D at startup. I do not attempt to hot-swap.
But I do not know if this is how Lightroom operates. If Lightroom stores any of this information on drive C will it be able to differentiate between the different drive D's it is confronted with ?
Geoff's reply suggests that Lightroom might store some or all of its database/library with itself on drive C. Even this might work if the missing files are shown in red. I would just need to select the right HDD to put into the machine for the project I want to work on. Hopefully this will work like the external drive situation Andrew has described. I am using sticky labels to identify each HDD with the projects it holds at the moment ....
Sounds encouraging .... Thanks for the help.

I want to change screenshot location from my Solid State hard drive with OSX on it, to my 2nd storage hard drive, how do I do this?
I am aware of "defaults write com.apple.screencapture *location*" but I want to change the location to my 2nd drive which doesn't have OSX on it... everytime I've tried to insert MacintoshHD2 in there it just doesn't work... any tips?I'm having the same problem. I've entered the following path in terminal:
"defaults write.com.apple.screencapture location /Volumes/Macintosh HD 2/[my username]/Downloads"
But it's not working. It keeps going to the SSD Downloads folder.

The circuit of my macbook is dead yet the hard drive is fine. I need to access a file from the hard drive, how can i do this? The mac turns on the screen freezes as bright blue. Is there a cable i can connect to another mac that will let me transfer the file?
There is another option if the Macbook will start up in Target Disk Mode.
Restart the computer while holding down the T key. If you see the firewire symbol moving around on the screen you can connect this one to another one in TDM. You will need a suitable cable to connect the two Macs.

Current computer that I just bought used is operating on Leopard 10.5.8
I have Mountain Lion OS X CD installation files downloaded on my external hard drive from another Mac that I have owned.
How do I use my external HD to download and Install Mountain OS X wizard.
Is the only way to do this to buy a copy of snow leopard and then once upgrading to that, plug in my external HD and then access the Mtn install file as I would if I had the installation CD?
When I try to access the install file from my external HD, i get to the installation window and then when I am to select a hard drive to install it on I receuve a red exclamation mark error that says it can not be written to the HD. Why is this? Because I'm not on snow leopard but rather leopard?As you have the installer on a DVD, you can do a trick that consists in formatting the hard drive, and then, install Mountain Lion.
First, make a backup of your files with Time Machine > http://support.apple.com/kb/HT1427 I recommend Time Machine because it will be easier to restore your files later.
Then, insert the DVD with Mountain Lion and hold the C key while your Mac is starting, so you will see a window with different options. Open Disk Utility, choose Macintosh HD in the sidebar, go to Erase tab and erase the drive.
After erasing the drive, you can install Mountain Lion. Close Disk Utility and install it. During the initial setup, it will ask you to restore your files, so plug the external drive with the backup and follow its steps. Note that PowerPC apps aren't compatible -
We are losing memory from the hard drive, how can we resolve this issue?
We are currently have a memory leakage from our hard drive. We have an Apple imac running snow leopard. The memory appears to shrink as we use our computer.. This is a conundrum for us, any advice on how to resolve this issue would be appreciated..
This is normal. Mac OS X dynamically assigns memory as needed. If you are down to the last 15% of free space, this can get out of hand, and I recommend keeping your hard drive clean of non-essential files*:

When i download a movie i want it to go straight to external hard drive how do i do this
I own a mac air 17" and i like to keep the memory as free as possible. I would like to know if i can have my external hard drive plugged in and download my itunes (TV shows & Movies) purchases direct to it.

How does FCP handle 23.98 DV Files?
Hi All,
Has anyone Edited using the DV-NTSC 24P (23.98fps) Easy Setup?
1) How does FCP handle this video connected to a DV Converter Box like the Canopus ADVC-110?
2) Does it actually play at 23.98fps on a monitor connected to the DV Converter Box?
3) Does it get converted to 29.97fps somewhere in the process before it gets displayed?
4) is it displayed at 29.97fps or is it really being displayed at 23.98fps?
these are things that I am not sure of.
sorry if I posted this message a couple of times. I didn't know that hitting the "Tab" Button posts the message, I thought it would just function like the Tab in a normal Text editor and indent a line. But here it doesn't.
thanks
KalaganHi,
Thanks for the feed back. I guess I should fill in the caps a little.
*DESCRIPTION OF ISSUE:*
One of our main Clients Disney, is migrating to a Tapeless Workflow based on ProRes HQ 422 @ 23.98fps. From here on out, they will only send us ProRes HQ 422 1920x1080 files @ 23.98fps and they want us to Edit every project we work on for them @ 23.98fps. At the moment, it doesn't sound like they care if we Edit our projects in ProRes HD or some SD format, but the important thing to them is that we edit @ 23.98fps.
PROBLEM:
Our facility doesn't have the infrastructure to support 25 machines accessing ProRes HQ 422 files. Our facility was built to support DV NTSC @ 29.97fps and we have been working this way fairly well, for a number of years.
SOLUTION:
I am trying to find a way to continue to us our current equipment and satisfy Disney's request to work on all their projects at 23.98fps, starting from 1920x1080 ProRes HQ 422 files @ 23.98fps. So, it was my hope to be able to take the 23.98fps ProRes files and export them to 23.98fps DV NTSC. This way we wouldn't have to reconfigure our entire Facility (which would cost a couple hundred Thousand dollars).
My approach was to:
1) Use Media Manager to render a new DV NTSC file at 23.98fps, which it does pretty well for the most part. It keeps the Timecode consistent between the two files (very important), but doesn't allow you to Letterbox the 16x9 video in the 4x3 frame, it just stretches it to fill the entire 4x3 frame (not so good).
2) Then import the newly created DV NTSC 23.98fps file into a FCP Project based on the DV NTSC 24(p) 23.98fps EASY SETUP. Which works well. No problems there.
3) Then Play the file in FCP out through a Firewire based Canopus ADVC-110 DV Converter connected to a SD Sony Monitor. This seemed to worked fine also.
The fact that it plays is great!!!! But, that brings up the question, is it really playing a 23.98fps?
My understanding of Standard Definition and specifically DV NTSC, is that it can only be displayed at 29.97fps, it doesn't support 23.98fps natively. So the fact that it played when I tested it got me thinking that I may be missing something here and DV NTSC and other SD equipment (like the Sony SD Monitor) can playback/support 23.98fps SD video. But that goes against everything I know up to this point!!!
Have I been wrong all this time?
1) Can SD Video and DV NTSC Video be displayed at 23.98fps?
2) Or is it getting converted to 29.97fps somewhere in the process before it is getting displayed?
3) If it is getting converted back to 29.97fps, then where is it getting converted, FCP or in the DV Converter Box?
I am sorry I went a little long on this email, but it is a problem that will have great influence on they way we work for a couple of years to come!!
Thanks for your input!!

How do i repair or recover data from a corrupt USB external hard drive that does not show up on my Mac desktop or disk utility?
Last night i was using my external hard drive, for some reason the folder just closed and i couldn't find it on my desktop.
After googling solutions, i found it in the disk utilities, i clicked on the 'repair' button many times, but it said the 'error...' message.
So i ejected it to try again, now when i connect the USB external hard drive it doesn't show up on my desktop or disk utilities.
I really just want to either repair or recover the data on it because it literally has everything (documents, work files, photos etc) on it,
I downloaded an application to recover my files but it needs the USB to at least show up.recognise it which mine doesn't.
I know i should've backed it up on another USB, this definitely teaches me for next time to back up all my files.
Are the files lost forever or can i recover them by going to a shop or using a software?Thank you for responding.
This might sound stupid since i'm not really knowledgeable with Macs,
but since all my files were moved from my mac computer to the external hard drive,
is it possible to recover those files through my Mac - like recovering deleted files? -
A year ago I brought a 1 TB hard drive (My Passport), I have not used it for over 4 months and now when I use the USB cord to connect it to my mac, it does not register the hard drive. Does anyone know why this is happening?
The beeps could be caused by something as simple as a loose internal wire or connection. If it is under warranty (not sure how long that is, as WD drives range from 1 to 5 years depending on the model's series - I think "my passport" drives are 3 years) you could contact WD and ask them about it.
If it is out of warranty, you could also try opening the case and check the connections - the drive may be fine, and there have been posts on TomsHardware forums of people getting the beeps, opening up the case and the drive is fine, just some wire worked loose. -

How to recreate iTunes Library
No content shows up in iTunes after updating -
My MacBook Pro hard drive is almost full and I wish to store my Aperture Library on an external drive, how do I do this and is the use of USB2 suitable or do I need to use a Firewire external hard drive?
You'll get better performance if you use a Firewire hard drive (especially if you buy a 7200 RPM drive). Firewire's IO speed is significantly faster than USB 2. USB 2 has a theoretical max speed of 480 Mbps except that it has extremely high over-head. The fastest speeds you can typically get are about 300 Mbps. Firewire, on the other hand, has very little overhead. The fastest speeds you can get are very nearly 800 Mbps. You will typically be constrained by the maximum read/write speed of the drive, not the speed of the I/O on the Firewire bus. Now if you had one of those nice shiny new Macs with the Thunderbolt I/O and a Thunderbolt drive (Light Peak) ... I think they alter space and time so that your data arrives before you know you want it.
Also... unless you want to buy a solid state drive (very expensive), try to keep your hard drives from becoming much more than about 60% full if you want great performance. A nearly "full" hard drive is, on average, only about half as fast as the same hard drive when nearly empty.
USB 2 will work perfectly fine... just not as fast.
Also... it's much safer to move the entire Aperture library than to "relocate masters". Your images must be managed. You can Aperture manage them, or you can manage them. But someone has to manage them. If you "relocate" them so that they are no longer stored inside the Aperture library then you'll need to work out a system of how you decide to organize things and it's critically important that you don't start moving files around or deleting things without Aperture's knowledge. If you do, you'll break the links to your masters and start having problems with missing masters. If you have Aperture manage the library then you don't need to worry about any of that stuff.... it's safer.
Do make backups (use the Aperture Vault or use some other backup program, but make sure you back up your work if you care about it.) There are only two kinds of hard drives in the world: (1) those that have failed and (2) those that are going to fail. There are no exceptions to this rule. Hard drives are cheap. Backup software is built into Aperture and into your Mac. -

I recently had to install a new hard drive in my computer. This caused me to have to reload all content back to my iTunes and iPod. I have many apps on my iPod and i don't know how to transfer those back to my iTunes. Can anyone help?
Right clicking on your ipod in the device list an d choosing "transfer purchases" will copy apps and bought media from iTunes to your computer. Due to the new iTunes library on your new HD, iTunes will erase your ipod during the first sync. To save your data to the computer take a look at this article about saving data from your device to a computer: http://support.apple.com/kb/HT4137
Basically it's backing up manually, transferring her purchases (apps and bought music), letting iTunes erase the ipod due to the new iTunes library, and restoring from the manual backup again, to get all the data and settings back.
Make sure your new computer account is authorized in iTunes. Disable autosync in itunes, connect your ipod, right click on it in the device list and choose backup.
This will save data, pictures and settings to itunes. See what's included in this backup here: http://support.apple.com/kb/HT1766
Transfer your purchases the same way to copy all apps and bought media from the Store to your computer.
Set up at least one contact and event on your computer to be able the merge your calendars and contacts after your ipod got wiped during the first sync.
The rest of the data can be restored from the backup you made.
Restoring: http://support.apple.com/kb/HT1414
Music is one way only, from the computer to your device, unless you bought the songs in itunes and transferred your purchases.
There is 3rd party software out there, but not supported by Apple, see this thread: http://discussions.apple.com/thread.jspa?threadID=2013615&tstart=0 -
I have to extract all files from a hard drive of a macbook pro that is no longer working. All I have to access the hard drive is a PC, is this possible, and if so how?
You could try Paragon HFS+ for Windows. That would allow you to read and write files from a Mac-formatted drive.
