LR4 starting up with external hard drives

Hi, I have downloaded the trial version of LR4. When I backup my documents (not photos) via my external hard drive LR4 starts up as soon as the computer recognizes the external hard drive.
How can I prevent this?
Thanks.

In your Lightroom preferences, make sure there is not a check box in the option to start Lightroom when a card is inserted. Even though the external drive isn't a card, it seems that the operating system does, and will start Lightroom for you. I didn't realize that until I started using a new computer. There seems to be a lot of fine tuning and tweaking to get everything working my way.

Blue screen on start up with external Hard drive connected

On start up Imac freezes on light blue screen with external hard drive connected via firewire. Starts okay without hard drive connected. I have repaired the drive with no resolution of the problem.

You might try starting the iMac in "verbose mode" by holding down command-V when booting:

That could show you some messages that might explain the problem.
Another approach is to launch the Console utility and look for messages dated around the time of a hang.

Possible confliction with external hard drive?

Hi guys, I'm sort of new here, but I could really use some help.
I love my iPod (30 gig Video), I've had it for just over a year, but last week it all of a sudden started screwing up on me. I'm sorry it's such a lengthy explaination, but I haven't been able to find help anywhere else... If you don't feel like reading it, essentially my iPod seems to be conflicting with my external hard drive.
I keep all my music on a 150gb external hard drive since my laptop's 30 gigs barely has any room left over with all the programs and photos I have on it. iTunes has worked fine in the past with playing/syncing music from an external hard drive but all of a sudden it's decided that iPod and Hard Drive don't mix.
When I have my hard drive plugged in by itself, everything is normal, and iTunes can play the music fine. Though once I plug my iPod in, iTunes and the whole computer freezes up. I get the usual "Do Not Disconnect" message on the iPod, and it seems to be doing something, but everything on the computer just stops. I can click the start menu, I can click the close button on iTunes, nothing happens... UNTIL I unplug my iPod. Then everything unfreezes and whatever buttons I clicked while the screen was frozen do their appropriate action. If I had clicked to close iTunes it would then close iTunes... If I closed iTunes while the iPod is plugged in (which does nothing), then unplug the iPod causing iTunes to actually close, I get a message saying that the iPod needs to be reformatted to work with Windows and I should restore the iPod within iTunes to solve that problem.
At the time, I hadn't tried the iPod alone, without the hard drive plugged in (since I keep the hard drive plugged in all the time), so I figured it was a problem with the iPod, rather than a problem with the hard drive.
So I took the "restore" idea, and went to my friend's computer, which is running Vista. He has iTunes, and his computer is fine. I plug my iPod into it, iTunes opens up, things work great. So the problem didn't seem to be with my iPod. I took the opportunity of having my iPod in a working iTunes environment on my friend's computer, and I restored my iPod, clearing all the songs off of it, which is not really a big deal, since all my songs are on my ext. hard drive anyway. I took my iPod back to my computer, and nothing changed, I still had that problem, and I then realised that the problem only existed while my hard drive was plugged in.
It was after I restored it that I realised if I unplug my hard drive, and have my iPod plugged in alone, everything works fine. It opens up iTunes, it's recognised by My Computer, things are normal, except for the fact that I can't do anything, since all my music is on my ext. hard drive, so I get to look at a whole library of songs with little exclaimation marks beside them. Syncing didn't do anything except transfer the handful of songs from my library that AREN'T located on my external hard drive to my iPod, and of course, once I tried plugging my hard drive in... frozen.
I managed to figure out that if I started iTunes with my hard drive plugged in (so iTunes would know that the songs are in the right location), then unplugged the hard drive, plugged the iPod in (so iTunes would recognise it), then plugged the hard drive back in, things would work alright, though when I tried syncing it, it went painfully slow and stopped after about 3 albums, and this process hasn't worked since, it just freezes up again.
I know I could just copy songs slowly to my computer, and sync them to my iPod from the computer rather than the hard drive, but that would take ages, and I'd like to have the problem fixed rather than to have to go through that process any time I wanted to change what's on my iPod.
So that's my problem. I've followed the "5 R's" that the support here seems to swear by, I have tried unistalling and reinstalling iTunes twice, I've uninstalled both iTunes and the iPod updater stuff, and then installed everything clean from the CD that came with the iPod. I've tried renaming the drive letters of my ext. hard drive and my iPod in case there was some sort of confliction there, nothing seems to have worked. I don't think I changed anything with my computer that would cause this change (I ever restored Windows to a date before this problem occurred), and as for the update to iTunes 7.4.1.2, I didn't update it until after this problem started, so it wouldn't have been caused by the update.
I hope that made sense... If anyone can give me some help as to how I can get my iPod back working on my computer I'd be incredibly grateful and thanks in advance!
If anyone knows what's going on, it's probably somebody here

This sounds like more of a Windows specific iPod problem. You may get better responses if you posted it in that specific section of the forums.

Issues with External Hard Drives

I hope this is the right forum for this one - please give me a steer if not! I've also posted it in 'Dock and Finder', but this forum seems equally appropriate, if not more so.
I'm getting repeated issues with External Hard Drives, including ones that I have been using successfully for months/years, suddenly failing to mount and then becoming 'unknown device' through the firewire branch of 'About This Mac'.
I've just bought a new hard drive on the grounds that the others had somehow failed, and the same problems are emerging. I decided to Repair Permissions on my iMac's internal drive, and am copying the results below, from repair runs conducted yesterday and today:

Does anyone have any ideas what is going on???

Many problems with the 10.5.7 update have been fixed by a Restart.
If that doesn't help, something may have gone wrong with the update. Download and install the "combo" update, from: http://support.apple.com/downloads/MacOS_X_10_5_7_ComboUpdate
If that doesn't help, try running the Apple Hardware Test, on the disc that came with your computer.
1. Disconnect all external devices (including the Ethernet cable) except the keyboard and mouse.
2. Insert the "Additional Software & Apple Hardware Test" disc that came with your computer.
3. Restart while holding down the "C" key. When the list of available startup volumes appears, click Apple Hardware Test and the right arrow.
4. When the Apple Hardware Test main screen comes up (after a moment), follow the on screen instructions.
5. If it detects a problem, an error code will be displayed. Make a note of it.

ITunes prone to freeze with external hard drive?

I have a near 100GB music library (I write music reviews for several publications) and therefore I keep my collection in a Seagate 300GB external harddrive that I connect to my powerbook via firewire. Well, the problem is that iTunes tends to randomly freeze up on me after a while of use. Usually after about half an hour of using iTunes problem-free (sometime sooner, especially if I'm listening to a song and managing my library simultaneously), it stops responding and I have to Force Quit. Moreover, sometime Force Quit won't work and I have to either simply unplug my hard drive (obviously not good) or do a hard shut-down of the computer (also, not good). I don't remember having this problem before I started using my external hard-drive.
Any insight would be GREATLY appreciated.

No answer for you here other than to register my bitter disappointment, first it was 7.x and now it's 7.1 still same problems; spinning beach balls when importing folders not to mention ridiculous gapless slowness and extremely long album art work downloads.
I have a 2TB Terastation over Airport Expresses, it was more than fine on iTunes 6.x. I trashed the plists, trashed iTunes and re-installed, de-clicked gapless off library (too late because you have to select songs first) optimized wireless, localised library (move it locally rather than selecting external) and.. . no improvement.
I find it absolutely amazing that a company that touts digital life hasn't even tested one of it's core software on external/networked drives.

Windows Easy Transfer (WET) Issues with External Hard Drive - "Can't read from the source file or disk"

I work for Office Depot, in the tech department. Basically, one of our associates was supposed to do a data backup, and re-install Windows 7, then transfer the files back. He used Windows Easy Transfer and compacted everything into a 163 GB file.
Now comes the hard part. When we try to put it back on his computer ((drag-and-drop to the desktop) which has been wiped back to factory settings using the recovery partition), it stops at 79.5 GB remaining (you know how it doesn't give you a % of completion,
it just shows how many GB are remaining) and then says "Can't read from the source file or disk" and gives you an option to try again, or cancel. It gets hung up on the same point each time.
Normally, this wouldn't be a huge issue, but the contents on the drive are his wife's architect blueprints and interior design stuff, along with wedding photos, etc, which are the only copies they have. On top of those, they have court documents and other
important files that we are unable to access now.
I wasn't involved with this transfer, so I'm trying to clean up the mess as best I can. I remembered that the customer's wife was Russian, and had some files typed with a Russian keyboard, so on and so forth. I wonder if that's the issue? If not, I really
have no idea how to manually extract things from a ".mig" file, or how to diagnose what area is potentially corrupted.
In light of this situation, we tried using "Recuva" to recover the files post-wipe, but everything was corrupted or unable to be opened, and it also extracted and recovered all of the "useless" photos, such as the skype logos, up and
down arrows for browsers, etc (it was 160,000+ photos).
Trying to avoid a potential lawsuit, unhappy customer, and costing the company lots of money to see if professionals can get into this external hard drive.
Other relevant information:
We used a Toshiba 500 GB (465 GB) external hard drive.
Customer's computer is an HP Pavilion P6000 Series (Model No. p6520y) running Windows 7 Home Premium 64-bit Service Pack 1.
Any other information that is needed can be provided, thanks in advance, and hopefully we can find a solution to this issue quickly!

I think there's a lack of understanding somewhere.
"If you even can't start the process, please unplug it from your new PC. Then head back to your new computer and plug
the external drive back in to your new computer. "
Unplug from new, head back to new, plug it back in? That doesn't make much sense! Haha.
I knew what you meant though, somewhat. When I search through the drives after clicking yes (Has windows easy transfer
already saved your files blah blah blah) I click on the transfer file and it says "Windows Easy Transfer could not open the file".
Rather than drag-and-drop the file to the desktop, I now tried to double-click on the file itself while it was plugged
into the computer. It opened, and it started transferring until it was about 70% completed, and then an error popped up saying "WET can't open the easy transfer file, make sure your USB device is plugged in or check your internet connection".
I checked, and the USB hard drive's light wasn't on. Now, I unplug it and plug it back in, and the light comes back on,
so I click Retry, and it resets the bar back to nothing and says "Transfer time: 1 minute".
Rather than continue trying, I clicked "Cancel" instead of Retry, and it says "Your transfer did not complete successfully."
It says to click "view report" for more information, but there's no "view report button".
At the moment, I am scanning the External Drive for bad sectors using the check disk tool in properties. It's frozen
at "0 USN bytes processed".

Backup problems with external hard drive

I bought a WD passport external hard drive and copied my itunes library onto a file there. I re-set the location of the library on itunes to the drive on the external hard drive. So far I have not deleted anything from my computer hard drive. However, when I am in itunes and click onto a song, nothing comes out of my speakers. Everything looks normal, as if the track is playing, but nothing is happening. I tried buying a new track off of itunes online, downloaded it, and installed it on my ipod; it plays fine, on my ipod, but will not play on the computer. Something is obviously wrong, but I can't figure out what has happened. Any help out there?
Thanks!

It sounds to me like your iMac is on it's last legs....at least the internal hard drive. If you can't make a new Time Machine backup I would advise you replace your iMac as soon as possible.
Assuming your three-week old backup is sound you should have no problems moving everything over to a new Mac. I would recommend you use the Setup Assistant that appears when you start up the new Mac (and note: It only appears the first time you start the new Mac; you can move everything over later on via Migration Assistant, but you may see issues with accounts if you opt for that route).
I don't think you need the Genius Desk for Setup Assistant. You only have to power up the new iMac, answer a few questions....select "....From Another Disk..." When it asks how you want to move everything over....connect up your Iomega external drive...and wait for it to finish. (Could take several hours depending on the amount of data you're moving).
A couple of notes:
1. If your Iomega is a Firewire drive you'll need a Firewire to Thunderbolt adapter to connect it to your new iMac.
2. If you need to load CDs or DVDs remember the new iMacs don't contain an optical drive. You would need to get an Apple SuperDrive or third part external burner if you need that functionality.
I'm puzzled by the comment made in Seventy One's post questioning the reliability of the new iMacs. I upgraded from a 24" early 2008 model to a 27" model and everything works flawlessly. I hardly ever see the beachball anymore.

Rescue and Recovery backup with external hard drive

When I first backed up my computer to my WD 1 tb external hard drive using R&R, boot files were placed on the drive. Recently, some files I had corrupted my external hard drive and I had to fully erase it. Now, after making the drive recognizable again, I went to go back up my computer using rescue and recovery. This time, it asked me whether or not I wanted to make the drive bootable, I said yes, but an error popped up saying I needed 1000 more mb, even though I had 931 gb open. The backup started anyway, but it did not include any boot files. Is there a way to make the drive bootable the next time I backup? What is the difference between nonbootable and bootable? Help? Thanks.

I do NOT have a external Hard drive. If you just zeroed the drive, it is blank. Go into control panel,administrative tools, computer management, disk management. See if you can get a PROPERTIES of the external drive and post a Screen shot of that here. This will show what partition(s) are there, Fat32 vs NTFS. My experience is after you zero a drive, You have to boot your system, then use a Vendor (WD) standalone format utility or windows Disk manangement format, Make partition, etc. The screen shot i need is the one that says: DISK 1 (d 298.09 GB NTFS
Healthy(active,primary partition). This is what my 2nd drive, D, says. 1 partion on the drive.
When i added my second hard drive, it was blank. Booted up, BIOS recognized drive, Then i Formatted it with windows disk managment. I then pointed R&R to take backups to that drive. Create rescue media then made a Master boot record, install standalone R&R boots files, then took the backup. This makes my 2nd drive bootable, should i ever care to boot my D drive up and have R&R standalone program in control. Thus i have 2 bootable drives. C boots into windows, D boots into the rescue and recovery standalone program. I can also boot my C drive into R&R by hitting PF 11 at startup (bios) time.
Which version of r&r you have? Which version of windows? Windows 7 changed the way Master boot records are written.
You can go into R&R, advanced menu, create rescue media. Point to your External drive. WARNING. make sure the do not destroy existing data block is checked. IF YOU ARE brave, uncheck the destroy existing data. This will erase everthing on the drive!!! <<Warning. And be sure NOT to point to any drive you really love.
Buts lets 1st get the screen shot requested to make sure the drive is FORMATTED correcly.

Mac air with external hard drive - not being found on Finder, Time Machine, Migration Assistant

I have been using an external drive (Imation Apollo) to access only, old files from previous computer (PC) on a new Mac Air. I had not transferred them across to new computer (didn't want to do that) just accessing them from the HD. It had been working fine until recently. Each time the external drive had been connected Time Machine would come up and ask if i wanted to use this drive for back ups, and I always chose 'Decide later'. So, as yetI hadn't as yet configured Time Machine to do back ups.
Recently I noticed that the extrnal HD was no longer showing up on Finder. Slight panic as i have 5 or 6 yrs of work saved on that HD
Further investigations - it's also not showing up either on on Disk Utility, or on Migration Assistant.
I've done the following:
Tried HD in each of different USB ports - made no difference, HD still not showing up
Tested different Hubs in each port with HD attached - no difference HD not showing up
Tried USB flash drives in the USB ports - These are working fine and show up on finder
Tried the HD on other comptuters (a PC though, don't have access to another mac to do this test)- working fine, the HD is showing up and is accessable
Interrogated the Console logs to try to see if the act of attaching the HD creates a log entry - couldn't find anything
Rebooted computer via shut down, power disconnect - no difference
Reset PRAM - no difference still not showing up
Reset SMC - no differnce still not showing up
So I think I have established that all the USB ports are functioning correctly and able to access other external drive devices, using hubs with external powersource is not the issue, identified that the external hard drive is working OK, and it appears that the Mac itself is functioning normally.
What would be the reason the Mac now does not allow this specific external HD to be identified and accessed. The only possible things I can think of are
if I had in fact pressed 'Do not use' when Time Machine asked 'do you want to use this drive for back ups'. Would that mean that the Mac now totally rejects this HD from being a source of accessible files - I hope not!
I also think that my husband may have disconnected the hard drive from my computer to access some stuff and he just yanked it out rather than use the safe eject method. Could this create an issue? The Hard drive works fine on his PC.
Why is my Mac Air now rejecting this HD and what can I do to access my historical files now.
Any assistance anyone can provide would be very greatly appreciated!
Thanks
Anna

I can't answer why it isn't accessing it, but I have a slightly related issue w my back up drive starting to get noisy.
Realizing that redundancy is safety for critical data. I talked to my brother about my situation the other day & he said he has 3 small Western Digital portable HDs that he rotates for backup. He even keeps 1 in the safe deposit box.
I have read for some time that we should have multiple back ups & also have our critical stuff backed up off site. Amazon HD reviews had a woman telling about how she was very backed up on multiple computers & hard drives, but they were robbed or burgeled & all of them were stolen including her thesis that was on the computers.
Hard drives aren't that expensive. I just bought a new Western Digital 1 TB drive for $89.99. I plan to use it to back up the Seagate that is getting noisy & then maybe alternate them.
Also, when I came back to Mac, I moved practially all of my documents to Mac. I think I just dragged & dropped or something. Photos, Office, & pdfs do fine that way. & then you could back them up to a couple of different external drives & remove from your MacBookAir.
Unfortunately I think most of us do not back up until crisis & then it may be too late.
Also use Time Machine. For the 1st time in my computer life, my computer is well backed up--although now realizing the need for redundancy so will start backing up to at least 2 different HDs alternatly.
So, not sure why it isn't working & hopefully you have come up w a solution by now.
I think what I would do in a situation like this, since you can access it on the Windows machine would be to transfer the data to the Windows machine & then transfer it back to a different back up.
I'm looking into backing up what I still have in Windows using a thumb flash drive. I think it should all fit ok now that they have the larger drives & I don't have very much left in Windows format.

Multiple (related?) issues with external hard drive connectivity

Apologies if this has been discussed but I have been unable to find a solution or explanation after searching here and on other forums.
I recently purchased an external hard drive (1TB Iomega Select Portable, bus powered, 2.5", USB 2.0). After formatting with two HFS+ partitions the device began disconnecting unexpectedly and afterwards was often not recognisable by my mac until I rebooted. I returned the product and had it replaced by another of the same model.
The replacement external hard drive worked fine at first but hours later began showing the same symptoms. _It now connects briefly then a few seconds later disconnects._ Occasionally it seems to mount and work fine, but the problem always comes back. In the times when it is working, _Time Machine recognises the drive but only backs up at a rate of about 1KB/s!_
_I don't know if this is a problem with the external hard drive, my USB ports, or settings on my mac._ Any advise you could offer would be greatly appreciated as I've run out of troubleshooting options with my limited knowledge of computers.
_**Some tests I've done:_
1) When it's not being recognised in Finder, it's also not recognised in either Disk Utility or System Profiler
2) At one stage after repeatedly disconnecting, two other external hard drives and two thumb drives that I know work fine normally also failed to mount, but strangely two wireless mouse USB receivers worked fine. Both thumb drives were formatted as FAT32, one of the external hard drives had one HFS+ and one NTFS partition, and the other was entirely NTFS. When they weren't recognised in OS X, the two FAT32 drives and the NTFS partitions of the external hard drives were all recognised in Windows 7 via VMWare Fusion. After restarting the computer all of them now work on both Windows 7 and Mac OS X.
3) I tried the external hard drive on another computer (a PC) and it was recognised in Vista's 'Disk Management' with both partitions marked as 'healthy', but it just called it 'Disk 1' rather than showing the names I'd given each partition.
4) When I first started transferring files onto the drive I often got 'error code -36', but found a solution that seemed to fix that by deleting the '._' files from the source folder through Terminal.
5) I've tried different USB cables, both USB ports on my mac, and also connecting with and without the secondary part of the 'y' cable that was supplied with it.
Thanks very much,
Andrew

I have the same problem with some 2.5 drives. My iMac on 10.5.8 sees the drive fine but my older 2007 Mac Book Pro 10.6.6 would not see it and now my new Mac Book Pro had problems seeing the drive from my old Mac Book Pro in that box. I had to use migration utility over the network that took 18 hours to copy my user over. I bought a new drive box and now the drive seems to work fine. I have ejected it a couple times and all seems well. I hope it continues to function properly.

Problems with External Hard drive, will not mount and errors in disk utilit

i have a powerbook g4 aluminum. i have an external hard drive for it. a simple tech 100gig portable drive, almost brand new. i dont know what happened to it, but one day i was starting my computer up with it attached. it wounldnt fully start up, said "waiting for local disks" so i uplugged the external hard drive. now it wont mount and will only show up in the disk utility of my friends macbook. i tried to verify and repair, and this is the message i got.
Verify and Repair disk “UNTITLED”
** /dev/disk1s1
could not read boot block (Input/output error)
Error: The underlying task reported failure on exit
1 non HFS volume checked
1 volume could not be repaired because of an error
Im in mexico writing a book and so i really need help on this one guys.

Hi, hjbugs, and welcome to Apple Discussions. Disconnecting the drive while your Powerbook was accessing it probably caused your problem. It may be repairable using DiskWarrior or TechTool Pro, but if you don't have access to one of those and aren't going to buy one, reformatting the drive with Disk Utility may be the only other way to make it usable again. If it contains data you need to recover first (i.e., data that isn't also stored on your internal HD or other storage media), download the free demo version of one of the data recovery utilities mentioned in this thread and use it to see what is recoverable. If the files you need are recoverable, buy the full version of one of the utilities and recover them.

What's 'best-practice' with external hard drives?

Hello folks,
I just got myself a 500GB LaCie d2 'Quadra' hard drive, and it works great - just as I was led to expect. Now I've connected it to my iMac with a FW400 cable. I've a few questions regarding general usage and 'best practice' when using an external hard drive like this:
1. Do I need to disconnect it (pull out the cable from my iMac) every time I Shutdown - and reconnect on Startup? Or can I leave it it and pretty much just forget about it?
2. Can I turn it 'on' and 'off' any number of times (using the on/off switch on the back) when working on the iMac? I might like to switch it off if I'm not using it for an extended period of time while still working on the computer. Is this okay?
3. When I'm not using the drive and the drive switch is 'off', can the drive still remain connected to 'mains' power? Or is it necessary to disconnect it from the 'mains' entirely?
4. I understand it's best to disconnect when 'Repairing Permissions?' Can this be confirmed?
Thanks so much.
Cheers!
Steve.

1. Do I need to disconnect it (pull out the cable from my iMac) every time I Shutdown - and reconnect on Startup? Or can I leave it it and pretty much just forget about it?
What I do is shut down my Mac, leaving it connected to the mains: the external HD, external speakers and other peripherals are all connected to a mains switch and I turn these off. There's no need to disconnect the cable: some disks spin down when the computer is shut down, some don't. It probably wouldn't hurt to leave it spinning anyway, though I prefer to shut it off at the mains. Incidentally I shouldn't disconnect the computer from the mains when you shut down: doing this will run down the PRAM battery and hasten the day it needs replacing, which is expensive.
2. Can I turn it 'on' and 'off' any number of times (using the on/off switch on the back) when working on the iMac? I might like to switch it off if I'm not using it for an extended period of time while still working on the computer. Is this okay?
I shouldn't do this: the most strain on a hard disk is when it is starting up, not when it is running: I should leave it running all the time the Mac is on. If you do switch it off, make sure to unmount it first (drag it to the trash) otherwise you will have all sorts of problems.
3. When I'm not using the drive and the drive switch is 'off', can the drive still remain connected to 'mains' power? Or is it necessary to disconnect it from the 'mains' entirely?
No: I see no problem in leaving it plugged in to the mains: the 'off' switch disconnects it anyway.
4. I understand it's best to disconnect when 'Repairing Permissions?' Can this be confirmed?
I've never heard this, and I can't see that there's any neccesity: the repairing process will be confined to the disk you have nominated to work on in any case.

Macbook pro, trouble with external hard drives

I just got the drive on my mid-2010's macbook pro replaced at Apple. I am now experiencing a new problem.
My macbook is having trouble with ALL my external hard-drives. After a few minutes of being plugged in I click on them to open and the finder window is blank. Its not allowing me to veiw the content stored on the drive. If I keep trying my computer will freeze. I try to 'Force Eject' the drive and it doesnt eject so I have to unplug then start over.
This seems to happen roughly about 5 minutes after I plug them in. They work fine the first 5 minutes. Its becoming extremly annoying. All my drives are different makes, sizes, etc.. so I pretty sure its the macbook.
What might the problem be?
Thanks,
Shane
