Would it be possible to make lightning have an option to store the library in another location? Id love to have the App installed on my faster SSD boot disk and point the program to its library on either my secondary internal HDD or potentially an external HDD for image storage. It would be nice to be able to store the images on a non boot volume. Also, the ability to extract the Images created with lightning independently from lightning for backup/storage reasons would be greatly appreciated.

Hi,

you can achieve this by symlinking the Library Directory to your external / non-boot Volume.
Just place a symlink in your users Library/Application Support/FileWave/Lightning folder that points to the "ImageLibrary" folder you have extracted.

The Content of the "ImageLibrary" folder described above would also be what you'd need to extract / backup the images.

Best Regards,

Chris,

I tried this and it doesn't see to work quite right. The symlink works to the point of seeing the images I have created, but when I choose an image and click "deploy", I get an error saying it can't scan for volumes.

The logs show an error along the lines saying "~/Library/Appplication Support/Filewave/Lightning/ImageLibrary" must be rooted in ~/Library/Appplication Support/Filewave/Lightning/ImageLibrary". The error of course showed the full path of /users/myaccount/Library.....

I just used the command "ln -sf /path/to/externalhd /path/to/original/lightning"

Any thoughts?

Thanks for the cool product!! VERY easy to use and build a clean image.

Chris,

When I try to make a symlink as you recommend, it appears to work ok until I try to deploy the image. It will see the images I have created, but when I try to deploy it gives me an error about not being able to detect volumes. When I check the logs, this is what I see...

10/4/12 2:07:58.600 PM Lightning: failed; the working directory (/Users/vernkollas/Library/Application Support/FileWave/Lightning/ImageLibrary/8524CB8F-CE10-4CF1-B2C8-96B3DB0C4598) of the task MUST be rooted at: /Users/vernkollas/Library/Application Support/FileWave/Lightning/ImageLibrary

I would LOVE to have my images on my external TB drive instead of on my laptop HD...

Any thoughts?

Thanks for the help and easy to use program...

Did you make a sym link or just an alias?

to make link
sudo ln -s /Volumes/VOLUME_NAME/target_folder/ ~/Library/Application\ Support/FileWave/Lightning/

and you are still getting that error?

Ben,

Yup... that is the command I used... I do not think I did a sudo though...

I should also add that my machine is running 10.7.5. When looking at the link in the finder, it adds the folder in the listing, but it does say "Alias" in the "Kind" column.

I will try it again with sudo and see what happens.

Sorry for the doubly post.. I missed the part about waiting for the moderator approval.

Thanks!

Vern

Ben,

Still getting the same error... I have attached the screen shot of what I see in Lightning.. The error is showing up in system log, if that is helpful...

I can attach the lightning.log file too if you like...

One work around I was thinking is to install an OS on my TB drive and boot from it when i want to image, but it would be nice to figure this part out.

Thanks for the help!

Yeah the booting form the other drive is actually preferred as it is faster (when machin is in Target Disk Mode, it actually dose not use the full bandwidth of the thunderbolt).

But I agree, this should be figured out.

Let me get one of the developers on this.

Can you expand upon how TDM does not use the full bandwidth?

What is it actually running at?
What causes this?
Is there a document from Apple stating this?

Thanks

Brad

Sure Brad,
From talking to Apple Engineers and in our own testing we actually see faster speed when booted from an external drive imaging the internal one, rather then booting a machine into TDM and imaging it from another machine. We personally haven't not run bench tests but I can get a 4.9gb onto a Macbook Air in about 38 - 42 seconds.

Here are some articles about other tests:
http://blog.macsales.com/10882-thunderbolt-via-target-disk-mode
http://www.anandtech.com/show/4489/promise-pegasus-r6-mac-thunderbolt-review/9

From what I have been able to gather on the speed difference is that in TDM requires some overhead and so the machine isn't running at full specification.

Does that help?
