Using with external HD

A basic question- Where can you keep your imported movie files?
Can an external HD be used? (I hope so!!) If so, can multiple computers access those files?
Do the files being worked on for eventual iMovei creating, need to be on the computer athe time?
Where is the final product file creted?
With the use of external HD, the issue of where things can be worked on, stored, and burned from is a tricky one for me.
Thanks

I know you're right about something being fishy--it doesn't make sense to me not being able to use some effects just because the projects are saved to the ext HD.
Yes, my ext. hd is hooked up via firewire. Is that a problem?
I don't know if the drive is formatted for Mac OS Extended. Can you explain more on checking it with Disk Utility? I'm new to these things! (I am a previous PC owner--though the HD was never used with my PC.)
If it is NOT formatted correctly, do i have to move the projects off of it and then format it? You're going to have to help me with that too!
Thanks for the help.

I want to control the front panel of a lab View program with C code??

I want to be able to run lab View via Corba. So I need some way to control my lab Vew programs with C code. I really hope this is enough INFO.

Hi Mikey,
As mentioned by the guru more details would help us help you.
Do you just want to start the LV app from Corba?
Do you need to specify start-up value for the LV app?
Do you want want Corba to Fiddle with buttons and controls on the FP of the LV app?
Please outline your "dream" and we will let you know what is possible.

Time machine on Lion crashes the whole system when used with external HD

Hi all,
Anybody got the same problem? I did a Time Machine backup just before I did the upgrade to Lion (using an external USB HDD) after the upgrade (that went well in my opinion) when I ask TM to do another backup it stays on "Preparing" indefenately and ultimately crashes the whole system ( reset with ctrl+cmd+power button) is required otherwhise the system stays non reactive.
Regards,
Iwan

Start by verifying your internal HD, and repair your backups, per #6 in Using Disk Utility.
If that doesn't help, see #D6 in Time Machine - Troubleshooting for a possible way to cancel the backup. If that works, use the widget in #A1 there to display the backup messages from your logs. Locate the backup in question, then copy and post all the messages here.

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.
Regards,
Scott

Creating a view using With causes ORA-00600 Error

Hello Ladies and Gents,
I've been trying to deploy a recursive query as a view in Oracle XE and Standard Edition, neither to much success.
The query is located in this question here: http://stackoverflow.com/questions/17358109/how-to-retrieve-all-recursive-children-of-parent-row-in-oracle-sq
with recursion_view(base, parent_id, child_id, qty) as (
   -- first step, get rows to start with
   select
parent_id base,
parent_id,
child_id,
qty
from
md_boms
union all
-- subsequent steps
select
   -- retain base value from previous level
previous_level.base,
   -- get information from current level
current_level.parent_id,
current_level.child_id,
   -- accumulate sum
   (previous_level.qty + current_level.qty) as qty
from
recursion_view previous_level,
md_boms current_level
where
current_level.parent_id = previous_level.child_id
select
base, parent_id, child_id, qty
from
recursion_view
order by
base, parent_id, child_id
The query itself works and returns results. However, when I try to create a view with that query, I receive errors.
I've posted two screenshots: http://www.williverstravels.com/JDev/Forums/StackOverflow/17358109/ViewError.jpg and http://www.williverstravels.com/JDev/Forums/StackOverflow/17358109/InternalError.jpg The first one with the ! and * is when I am using JDeveloper 11g, using the Database Navigator, right-click on View and select "New View". I receive the error when I click OK. I can indeed create the view through a sql script, but when I attempt to view the data, I receive the ORA_00600 error.
I've tried this on both my local machine for XE (version 11.2.0.2.0) and on 11g Standard Edition (11.2.0.2.v6) via Amazon Web Services. The result is the same.
Does anyone know how to get around this?

Not 5 minutes after I post this, I decide not to use JDev's graphical editor, and simply write
SELECT * FROM BOMS_VIEW;
And it works like a charm. I just can't use data tab to view the records in the editor. Wish I had known that 5 hours ago.

DVD Studio Pro 4 USE WITH EXTERNAL DVD BURNER??

Hello
Looking at buying DVD Studio Pro 4 for my mini but apple have just stated it will not install unless my machine has a superdrive. We've got an external firewire DVD burner and i've read mention of other versions of DVD Studio burning through externals so how come we carnt use DVD Studio Pro 4 with an external DVD burner?
Has anyone tried an external DVD burner with DVD Studio Pro 4 ?
Cheers

This issue isn't external drives, it's the mini, and installing the program.

The specs do not seem to require an internal superdrive.

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.

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.

Lab view Application with a Customized Title bar

I am using Labview 2013. I need to change the color of the Application Title Bar to Black. I dug around quite a lot but did not come across any method to do this. Any suggestions or ideas?
Thanks,

Can a 488.2 controller be used with 488.1 device?

I was wondering if a 488.2 controller can be used with a 488.1 device? I have used the same controller with 488.2 devices with no problems but not with a 488.1 device.

srm,
A 488.2 controller (such as any of NI's GPIB boards) is backwards compatible with a 488.1 device. Both use the same digital communication protocol to address the bus. The main differences in 488.1 and 488.2 are the status model (which is also backwards compatible, 488.2 just added additional functionality on top) and that the 488.2 specification added additional software specifications, such as a common command set and syntax & data structure guidelines, that a 488.1 device would not necessarily understand. So if you were trying to address a 488.1 device using commands or programming calls specific to 488.2, this could be the cause of the problem. I know these abilities are separated into two different palettes in LabVIEW, I'm not sure exactly how they are separated in the text-based languages.
Regardless, a 488.1 device should show up when you "Scan for Instruments" with your GPIB card in MAX. Some things to check are that the GPIB card is installed with the proper drivers (the latest verison of NI-488.2 compatible with your OS) and is detected by Windows and MAX, the cable connections are made properly and the instrument is powered on and has its GPIB interface configured with an address that does not conflict with another instrument. Hope this helps clear up the confusion, have a good day!
Sincerely,
Ross C

Using iPhone/iPad Recovery Mode

Saw this solution on another post about an iPad in a school enviroment. Might work on your iPad so you won't lose everything.

‘iPad is disabled’ fix without resetting using iTunes
Today I met my match with an iPad that had a passcode entered too many times, resulting in it displaying the message ‘iPad is disabled – Connect to iTunes’. This was a student iPad and since they use Notability for most of their work there was a chance that her files were not all backed up to the cloud. I really wanted to just re-activate the iPad instead of totally resetting it back to our default image.
I reached out to my PLN on Twitter and had some help from a few people through retweets and a couple of clarification tweets. I love that so many are willing to help out so quickly. Through this I also learned that I look like Lt. Riker from Star Trek (thanks @FillineMachine).
Through some trial and error (and a little sheer luck), I was able to reactivate the iPad without loosing any data. Note, this will only work on the computer it last synced with. Here’s how:
1. Configurator is useless in reactivating a locked iPad. You will only be able to completely reformat the iPad using Configurator. If that’s ok with you, go for it – otherwise don’t waste your time trying to figure it out.
2. Open iTunes with the iPad disconnected.
3. Connect the iPad to the computer and wait for it to show up in the devices section in iTunes.
4. Click on the iPad name when it appears and you will be given the option to restore a backup or setup as a new iPad (since it is locked).
5. Click ‘Setup as new iPad’ and then click restore.
6. The iPad will start backing up before it does the full restore and sync. CANCEL THE BACKUP IMMEDIATELY. You do this by clicking the small x in the status window in iTunes.
7. When the backup cancels, it immediately starts syncing – cancel this as well using the same small x in the iTunes status window.
8. The first stage in the restore process unlocks the iPad, you are basically just cancelling out the restore process as soon as it reactivates the iPad.
If done correctly, you will experience no data loss and the result will be a reactivated iPad. I have now tried this with about 5 iPads that were locked identically by students and each time it worked like a charm.
~~~~~~~~~~~~~
Try it and good luck. You have nothing more to lose if it doesn't work for you.
 Cheers, Tom

Synchronize with External NTP server.

If external NTP device is down will have any impact in the cluster setup?You should configure the cluster nodes as peers as well as getting the time from the external NTP server.
If the external NTP server fails, then time will drift, but at least the cluster nodes keep themselves in sync to have a consistent view.
