Db in External hard disk.Will it impact the performance.

I need to create a db in external harddisk connected to the server since we ran out of space.
How much will it impact the performance

It depends on the transfer rate of your external disk.
For example, a normal
Firewire 1394 is at 50MBps
Latest ATA-133 is at 133MBps
Ultra320 SCSI is at 320Mps

Imposible continue the installation of Snow leopard 10.6 on a 1TB external hard disk, what can I do?

Imposible continue with the installation of Snow leopard 10.6 on a 1TB external hard disk. I did the same last year and I continued working but suddenly appeared the simbol with a folder and a question mark and I know this is a problem so I click in the format option to the hard disk and when I tried to install again Snow Leopard, 'cause I want to recover my backups with Time Machine, I couldn't continue because the installation didn't respond to the click in the Utilities option or to next step > continue . Please, What can I do? I'll wait for your answers. Thank you so much in advance.

Hello Melophage,
It is the original hard drive which should have been erased by the previous owner. The problem is, I cannot access it without any OS installed. Or maybe there is a bootable USB or DVD that can do it ?
Just an indication: when I boot without CD inserted in it, it shows a grey folder icon with a questionmark like this one:
Thank you for your help
PS: Yes, I am interested by the replacement pair of grey installation DVDs for my model. Where can I purchase this ?

ITunes showing Album Covers of external hard disk i/o internal hard disk

Greetings from Malaysia again. Searched through the Discussion Group, but couldn't find anything there. Thus, hope to get your assistance on this matter.
I have some music stored in the internal hard disk of my G4 iBook. However, recently I decided to have all my music stored in an EXTERNAL hard disk, ie in addition to what's in the iBook, to sync with my iPod. Both have the artwork or album covers. The issue is when I boot up ONLY the iBook, even without the external hard disk on, iTunes (Version 8.1) is showing the Artwork/Album Covers (and list of music) of the EXTERNAL hard disk instead of what's in the iBook. I've even tried the "Option key/Choose Library", but to no avail. I've even tried changing the location, after starting up iTunes in the Preference settings, but still the same story.
Is there any way to have iTunes reflect the correct Artwork/Album Covers (and list of music) when I have the external hard disk connected, as well as otherwise?
Thanks in advance for your help.
Regards.

Moved the existing library. Created a new one, and moved all the songs to the new library. Subsequently, when using the "Option" key to select the library, it ended up as what I wanted, ie iTunes showing the album covers for the songs/album in the respective library - ie external hard disk, and internal in the notebook.

Problem with Lightroom 5: how to connect the app with my original pictures which are on a external hard disk and, once this resolved, how to create virtual pictures

A friend has installed Lightroom 5 on my MacBook air. he transferred all my picture that were on my IPhone an on Iphoto on Lightroom but without making virtual copies systematically. He put the original (real?) pictures on a external hard disk under Data_photos folder to allow more memory space on my Mac book Air. My problem now that when I connect the external hard disk with my computer the connexion does not happen automatically. it is like if Lightromm does not recognize the path to get connected to the original/real picture and therefore I cannot see pictures with all their potential and I cannot work on these. I am stuck! What should I do to 1) create this link? 2) create then virtual copies in order to be able to work on my computer without been obliged to connect my external hard disk to be able to use the application Lightroom. The friend who helped me disappeared! He is not in Japan and unable to help me.I hope you can help me. I have been looking for support to apple stores, photo shops, computer specialists but I have not found the expert capable to help me. I am leaving in Geneva. And believe that I should have some one with me physically to resolve a problem which I believe is not a serious one if one knows lghtroom an dinformatic basics... thank in advance to come back to me asap !!!!

HD Video and External Hard Disks

Howdy.
I'm having a strange problem with HD video footage (1080p from various sources) and playing it back from external hard disk.
Here is the situation:
I have a new 17" Macbook Pro; if I play 1080p video directly from the internal drive, it plays with no problems at all.
I have a 1TB USB 2 external drive; 1080p video also plays back fine from this drive.
I also have 2 G-Drive's; both with a capacity of 1TB each and connected via FireWire 800 and when I try to play 1080p footage from either of these drivers, the video is very stuttery.
Now, it would be easy to say "well the G-Drives but be operating slowly", but if I copy files between them and the internal drive, the files copy very quickly; much quicker infact than copying files to the USB2 drive.
So for all transferring of files the G-Drives are much quicker than the USB2 drive.
To make matters even stranger, if I connect the same G-Drives to the MacPro we have at work, the 1080p video plays back fine.
So it seems to be the combination of my MacBook Pro + the G-Drives that dont like playing 1080p video (since the drives on another computer play fine, and my macbook pro plays the same video fine from both the internal and usb2 external drives).
It's got me baffled.
Anyone have any idea whats causing this?
Thanks.
James.

The USB drive is older but for my first tests, was actually NTFS formatted (since Id been using it on my windows PC); the files played fine even with the NTFS formatting and over 200GB of files on the drive.
I then wiped the drive and formatted as Mac OS Extended, transferred a couple of video files and played them, again they played back fine.
The thing is, if I simply move/copy files between internal drive and fire wire drive; and from internal drive to USB drive, the fire wire drives are clearly much faster.
So it's not like the fire wire drives are running slow, the problem is only in the playback of the files.
Also, as I have 2 of these fire wire drives, 1 drive is empty appart from the video files im trying to play (less than 200MB), the other drive has about 200GB on it and the video doesn't play properly on either of them.
But as i said, if I simply connect the drives up to the MacPro we have in the office, the videos play back without a hitch.
So it seems the problem is specific to playing video back from the g-drive in combination with the macbook pro (general file operations happen very fast); individually if separated and used with another device they work fine.
EDIT:
Forgot to mention.
I also tried setting the 2 fire wire (G-Drives) up as a striped raid.
Again, when moving/copying files between said raid and the internal hard disk, the transfers were very quick; but the video files (which come from various sources, i.e canon 7d slr camera, gopro HD helmet cam etc) all fail to play smoothly even from the raid.

Restore a external hard disk

Hello,
Can I restore old rman backup on external hard disk with USB3? the size of database is 430 GB.
Thank you.

damorgan wrote:
I have never tried but I would hope the answer is no.I have done it, and the answer is sadly 'Yes' ;-)
RMAN doesn't have any opinions on where you restore your backups, as long as the disk area is addressable in your system (i.e. mounted with a path/letter, depending on your OS).
But on the other hand, I wouldn't do this on a production system, only for backup/recovery verification/development system creation.

I want to move imovie projects and events to an external hard drive. Where is the "move" command?

I want to move completed imovie projects and events to my external hard drive. I see in the "help" section that I should "move project & event" and they indicate that their should be such a selection. I highlight the project I want to move and attempt to drag it to my external HD but it won't stay. I never see "move project & event". I've tried holding the "command" key down while dragging and that doesn't work either. Help ...

Hi
Moving Event's and Project's
Connection - Either connect one Mac in Target mode to the other via FireWire. Or use an external hard disk !
(Target-Mode - Start one Mac e.g. laptop - BUT keep T-key down during full up-start - Now a FW-symbol is jumping around the screen and it will work as an external hard disk when connected to the other Mac)
A. The External Hard Disk - MUST BE - Mac OS Extended (hfs) formatted to work for Video. UNIX/DOS/FAT32/Mac OS Exchange works for most other things but not for Video whatever program is used (iMovie or FinalCut)
B. Should be a FireWire one as USB/USB2 performs badly to me and especially when filling up
C. Do never Move or Alter any folder named
• iMovie Event's - or -
• iMovie Project's
on DeskTop/Finder - as this will result in iMovie losing connections to them and repair can be anything from hard to impossibly
D. Moving and Copying must be done within iMovie application and Events to Events - and - Project's to Project's.
E. Moving Project's to Event's - Do not work for me - I have to export project as a QuickTime movie then Import this into Events.
Event's window can show two faces
Like this
or like this
from one hard disk Event - You can move it to the other hard disk
You can not (at least not me) move Event to Project or other way around only
Event to Event and Project to Project

How do i retrieve file vault protected files from an external hard disk that used to be my mbp's hard drive? the hard disk got corrupted and will no longer boot. I put it in an enclosure and attempted to copy my files but failed because of FV encryption.

This external hard disk used to serve as the main drive of my mbp. It got corrupted and the OSX would no longer load. I upgraded to a 500gb hd and used the old hd as an external drive. I tried to copy my files but i could not access them because of the filevault encryption. 110gb of hd space appears as used which means that my files are still in the drive. Is there a way to retrieve these files? thanks

According to your post, you're using Leopard, so FileVault only encrypts your user folder (unlike Lion). On the mounted external drive, in your user folder, you should see a file called username.sparsebundle, with username being your user name. Double-click that file to open it and it should prompt you for a password. Type in your password and the file will mount as a volume in Finder. You should be able to copy all of your files over.

If i move my iphoto & iMovie source library / Events and Projects to an external hard disk, due to size, will my existing slideshows work ?

I need to move my photo library and Movies (Events and Projects) to an external hard disk as my 700gb drive on my iMac is now full (*see note below)
I have brought 2 Samsung External drives (3TB each) which I plan to partition each for Photos and Movies i.e 2 partitions on each drive, and will use one for use with iPhoto and iMovie, and the other drive for a dedicated backup. I will backup the remainder of my iMac hardisk to a seperate disk.
What has just occured to me is that after I have moved the libraries I cannot see how existing iMovie projects and iPhoto Slideshows will work, as each Application will be looking for the source files on the original iMac hardisc (I assume).
I am running Snow Leopard v10.6.8 ( I did not want to upgrade to Mountain Lion as I was told the iPhoto and iMovie changes were a 'backward' step. However I now want to upgrade to Mountain Lion, for security updates reasons mainly, and so need to free up my hard drive.
Can anyone advise on the best way to proceed ?
* - the iMac hard disk become full very suddenly, possibly due to duplicates, as I have noticed duplicate events and clips in my iMovies event library. I have noticed that some events are also now not showing, with message 'No video clips match the current selection' (I have not search criteria set).
Thanks

I was planning on manually backing up my external to the time capsule - but is there a way to set it up to back up automatically instead?
Time Machine will backup up automatically - you can not have your iPhoto library on the same volume as the TM backup (it will not work and it would not be a backup)
Dragging the iPhoto library to any external drive will backup it us also
I was also thinking about having the library copied to another external (I mean we're talking about irreplaceable photos here) - would i just drag a copy of the library to that drive as well?
Yes - that is a good idea - I run TM giving me hourly backups and a daily clone of my entire system giving me a bootable backup - plus do an occasional TM backup at our second home so I have one off site
is it possible to deal with my imovie library in the same way? so all my movies and photos are on my external?
Probably - but I use iMovie very little - better question for the iMovie forum

My external hard drive will not open and only shows up in Disk Utilities. When I try yo repair it, it give me and error of invalid sibling link. How do I fix my external hard drive?

My external hard drive will not open and only shows up in Disk Utilities. When I try yo repair it, it give me and error of invalid sibling link. How do I fix my external hard drive?

Invalid sibling link may not be fixable by Disk Utility. (Disk Utility is very conservative, and will not attempt repairs that might cause you to lose data.)
It is an indication of serious Directory damage.
that leaves
a) third-party Utilities that will take those risks, or
b) re-initializing the drive (which deletes all your data) and restoring from another backup source.
c) "Copying off whatever files you can salvage" has gone by, and you cannot copy anything off a drive that will not mount. You may be able to use "rescue" programs such as prosoft engineering Data Rescue to copy files to another drive, but that sounds a lot better than its reality. You may get many files, but not get ANY filenames.

Is it safe to keep downloaded movies in the Macbook Pro or do I need to use an external hard disk for those ? Please suggest.

Is it safe to store the downloaded movies from iTunes in my Macbook Pro or do I need to store those separately in an external hard disk ? Please advice.

It will be no better or worse than any other video file and should not be responsible for any system instability. As I alluded to earlier, video takes up a lot of space and you can quickly use up that 200 GB of space. Download a few files to you MBP and see what impact it has. I have a couple of external HDDs dedicated to video files (and backups of same) due to the large file sizes.
If you find that space is getting tight on your MBP, then get an external for the video files and another one to back them up. I have a couple of external HDDs dedicated to video files (and backups of same) due to the large file sizes.
Ciao.

HT201269 I am trying to save memory on my iPhone 4S/ ios6. Can I back up all photos to icloud and the external hard disk I normally use for photos? If I then delete photos from the iPhone do the get deleted on iCloud?

I am trying to save memory on my iPhone 4S/ ios6.
1) Can I back up all photos to icloud and the external hard disk I normally use for photos? If I then delete photos from the iPhone do the get deleted on iCloud?
2) Can I back up the newsstand to iCloud and save memory on the iPhone?
3) Can I back up the bookshelf to icloud and save memory on the iPhone?

1. What format is the external drive? It sounds like it's ina format that Macs can't write to. Is it a NAS or NTFS?
2. Easiest thing: just move your iPhoto Library to the external
Make sure the drive is formatted Mac OS Extended (Journaled)
1. Quit iPhoto
2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.

My external hard drive will not show up in iMovie 10.0.4. How do I copy my movies into it?

My Mac OSX 10.9.4 has both iMovie 10 and iMovie 9. I've started uploading all of my videos from my camera to iMovie 10 and have not worried about my external hard drive. Now it's been a couple months of putting those videos onto iMovie 10 and I just connected my external hard drive and it doesn't show up in sidebar anywhere. Is this new to iMovie 10? How can I copy my events and projects to my external hard drive from imovie 10?
If iMovie 10 is the issue, I will gladly begin using iMovie 9 again, but will need those events to get into iMovie 9. Is there anyway to move movies in iMovie 10 to iMovie 9.
Thanks for the help!

Hi bwright22,
Welcome to Apple Support Communities.
It sounds like you want to copy videos to and from an external hard disk in iMovie. Take a look at the article linked below, I believe it has the information that you're looking for.
iMovie (2013): Work with multiple libraries
http://support.apple.com/kb/PH14745
Show or hide the Libraries list
You select libraries and events in the Libraries list.
To show the Libraries list: Click the Show button on the left side of the toolbar.
To hide the Libraries list: Click the Hide button on the left side of the toolbar.
You can also choose Window > Hide Libraries (or press Shift-Command-1).
Copy or move projects, events, or clips between libraries or hard disks
Connect a hard disk that contains the target library to your computer, or copy the target library to your computer.
Choose File > Open Library, and choose an option from the submenu.
You can choose from recently opened libraries at the top of the submenu, locate an existing library on your computer, or create a new library.
The selected library is opened in the Libraries list, with the first event selected and its contents displayed in the browser.
In the Libraries list, select the event that contains the item you want to move or copy.
In the browser, select the item you want to move or copy.
Note: To select multiple items, hold down the Command key as you click the items you want to select, or drag a selection rectangle around the items.
Do one of the following:
To move items between events or libraries: Drag the clip or project to another event or library.
To copy items between events or libraries: Option-drag the clip or project to another event or library by first starting to drag and then holding down the Option key as you drag.
I hope this helps.
