Proper shutdown Imac with external hard drives

I have an Intel Core 2 Duo Imac. I have a USB 2.0 external drive for Time machine and a firewire external drive for my Photos.
3 questions
1-can you just turn the computer off without concern for the drives (ie) should we put them away first or just turn the computer off?
2-when you install apple software updates, the computer needs to be restarted, do we just restart and not concern ourselves with external drives?
Sometimes I shut all 3 down to be environmentally sensitive. After I turn the computer off, i turn off the power strip to the external drives. the last time I did this, I had a hard time getting the photo firewire drive to mount, it finally did after some manipulation of cords and downloading latest OSX software update. what precautions do I need to take.
thanks for answering this!

can you just turn the computer off without concern for the drives
Shutting down the computer normally automatically puts the drives away. If you're going to force it to shut down or restart for some reason, eject the drives first.
do we just restart and not concern ourselves with external drives?
See above. Some updates may recommend that the drives be unmounted manually first.

  • Proper Backup Procedures with External Hard Drives

    I use external firewire drives for all of my photos and I have a quick question about backup procedures. I currently use Intego's Personal Backup X5 software solution and I wanted to know whether it is better to backup your files or Sync your files when making duplicate drives?

    Aperture's vault function will "sync" your library with your vault. This means that the vault will only hold one specific version of your library, which is fine for most users. The vault file will be more or less the same size as your Aperture library file.
    If you want to make incremental backup of your library (which will allow you to restore specific versions of your library) then you could take a look at "Backup 3" which can be downloaded in a trail version here:
    http://www.mac.com/1/solutions/backup.html
    Incremental backup will mean that your initial backup file plus all your incremental backup files will fill up more space on your harddisk than the size of your Aperture library. (incremental = adding)

  • 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:

    Permissions repair complete
    My concerns are:
    * Some of the permissions repaired yesterday appear to have needed to be repaired again today
    * There are several files which carry a warning that they won't be repaired as they have been 'modified', and some of these clearly relate to disk management.
    Does anyone have any ideas what is going on???
    Thanks!!

    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.

  • 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:
    http://support.apple.com/kb/HT1492
    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.

  • When ever the power goes out or I restart my iMac the external hard drive that is used by Time Machine for backups is dismounted ?

    When ever the power goes out or I restart my iMac the external hard drive that is used for backups by Time Machine is dismounted and all backups are gone. I can reselect it and it will start working again, but I am worried if the iMac hard drive should fail will I be left without a backup ?

    It's possible a heavy-duty 3rd-party disk repair app can fix it, but they're expensive (DiskWarrior is about $100), and there's no guarantee it can do it.
    Am prompted to reformat but I don't have a good understanding of what this means and how to do it.
    That will erase it.  See Time Machine - Frequently Asked Question #5.
    It sounds very much like the disk is beginning to fail, although it's possible there's a bad port, cable, connection or power supply (if it has its own).
    I'd suggest getting a new one, and using it for your Time Machine backups; once you have a good backup there, reformat the old one (and select Security Options to write zeros to the whole drive -- if that fails, you know the drive is toast).  Use it for secondary backups, per FAQ #27.   If it has failed, get a second new one for secondary backups. 

  • TS1600 I received a 2008 Imac with erased hard drive.  I have the two discs to install OS X but when it tries to boot just  comes up Mac OS X cannot be installed on this computer. Is there anything I can do to get this running

    I rceived a 2008 Imac with erased hard drive.  They gave me the two install discs but it keeps coming up cannot install OS X on this computer.
    Is there anything to do. Thanks hopefully

    Well, Apple would probably point out that what you are trying to do violates the EULA.
    Technically speaking, however, the issue is that the install/restore DVDs that ship with Macs do not carry all the drivers, or even all of the various versions of libraries that support all of the various models of Macs. The come-with-your-Mac disks are different than the retail versions of the OS (also, the come-with-your-Mac ones bundle iLife, which the retail ones don't).
    Because the come-with-your-Mac disk contains only the drivers specific to that generation and model line of Mac, it contains a stub of code that verifies that your hardware matches the driver set on the install/restore DVD.
    Your friend has a different model of Mac, with different hardware, so her install/restore disk won't work in yours. Solution: go get the retail boxed version of Leopard.

  • I did backup from my Imac to external hard drive, how can I unzip that backup to my mac

    I did backup from my Imac to external hard drive, how can I unzip that backup to my mac again

    It may be Time Machine, but Time Machine doesn't store backups in .zip folders. Open Finder and select your backup external disk in the Finder sidebar, under "Devices". If you are using Time Machine, you should see a folder called "Backups.backupdb".
    If you are using Time Machine and you want to restore a full Time Machine backup, there are different methods depending on the Mac OS X version you are using. Open  > About this Mac, see Version and tell me what version you are using

  • How to get batch recognition of (!) on some tracks after moving library from external hard drive to new iMac (with terabyte hard drive)?

    I'm using Lion 10.7.2 and iTunes 10.5.2
    I have moved my iTunes music from an external hard drive onto my new iMac (with a terabyte hard drive) with music folder organized - when I try to play some tracks I get the iTunes can't locate warning and so I follow through and show iTunes the track - they are all in the music folder on my iMac hard drive - they all copied over and they all appear in the iTunes library list - so far as I can tell out of a 500 gigabyte music collection - but there are so many giving me the error - many other tracks function as they should too, some work others don't - So I'm looking for a way to get all the error tracks fixed in a batch correction way. Doing this individually with each track just isn't realistic.
    Can anyone suggest how I might fix this issue?
    Also, after I show iTunes the song location and it plays, I get a find files prompt that looks like it wants to find other files, but that just causes the process to jam and I have to force quit iTunes and then it doesn't remember what I last showed it next time I open iTunes.
    Also I'm trying to avoid the use of the consolidate function because that would copy a whole other set of music - not in iTunes - that is in the process of being edited (audio hijack pro and fission tools being used to put vinyl and tapes to mp3) But all that other music just means the consolodate function across my whole computer would be too much.

    Some details seem to be coming into focus - I have started scrolling through the main library list A to Z repairing tracks individually (there are thousands, but it's what works so far) - as I work through, it appears the problem occurred on tracks where album artist metadata was different than song artist metadata, predominantly. I'm not sure that is 100% the case in every instance, but that is what it's looking like. I don't why that happened, must be some technical glich I guess.
    Also, I tried running Doug's Scripts - the one titled, iTunes Track CPR v1.3 - it is supposed to fix exactly the kind of issue I'm having - I bet it would work for some people with a similar issue - but for my case it only identifies the 'de-linked' tracks and doesn't repair them - that is at least helpful as I scroll though to fix them - I can see exactly which tracks have the issue quickly after running that script - but iTunes doesn't remember that warning symbol after a log-out, so it's only worth running the script on a set of tracks I intend to review and fix in any given session at a time.
    If you are interested, Doug's free scripts can be found at
    http://dougscripts.com/itunes/scripts/ss.php?sp=itunestrackcpr
    there are other interesting and useful iTunes scripts there too...
    also, unrelated to the issue I'm having, I found a lot of really useful and time saving metadata fixing free scripts at - hubi's iTunes scripts - the page isn't English, but the script download is easy to find -
    hubi's scripts work for batch selections of tracks - so if you import an album and find the metadata screwed up somehow, you can select the whole set of screwed up tags at once (even across a series of albums), run the easy to use script, and watch it all be fixed automatically while you sit back and relax...
    http://hubionmac.com/wordpress/category/softwareschmiede/applescripting/itunes/
    just for reference, here is a sampling of what hubi's scripts can do...
    there are other useful scripts out there - the tough part can be finding the one that helps you...
    01-(un)capitalizes
    01-(un)capitalizes
    This script changes.... THIS TEXT into This Text... or this text
    01-Delete spaces
    Sometimes invisible blanks are behind an artist name or album name...this script deletes these blanks behind or infront of the strings
    01-Delete x first-last chars. of Title
    A Name like "01--Ray Of Light" will be changed to "Ray Of Light" and the01 will be entered in the tracks tracknumber id3 field =)
    01-fix combined Artist-Title
    Sometimes Tracknames look like:
    "Madonna---Ray of Light" and in the artist field you see something like"Ripped by Me"... this script puts Madonna back to the right field... all youhave to do is to enter the right delimiter ("---" in this case)
    01-switch Artist<->Title...
    Switch ID3 field a with ID3 field b (not only Artist with Title any more =)!
    01-z_filename ->Title
    Sets the ID3 field Title to the track's filename)
    01-z_trackNr-Filename->ID3
    When a track's filename look like "01-Madonna-Ray of Light.mp3" andyou don't have the track's tracknumber stored in the ID3 Tag... this Scriptcan do this for your =)

  • 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.

  • 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.

  • 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.

  • Using Time Machine with External Hard Drive

    Hey everyone,
    I had a few questions about Time Machine that I hope someone could answer for me.
    I bought my first external hard drive in August, the 1 TB WD My Book for Mac and when I set it up, I configured it to Time Machine, and not the WD software.
    I have an extensive music collection, which was my main reason for buying the external hard drive in the first place.
    Anyway, when I plug in the hard drive and let Time Machine do the back up, I've noticed that it's backing up the same files every single time, and is eating up a lot of space on the hard drive.
    Since I am mainly using this drive to store my music, I was wondering if there was an easier way to do things:
    -Is there a way to not back up my documents, photos, applications, etc, every single time I plug in my HD?
    -Is there an easy way to find my music on the drive? For example, some Time Machine back-ups have different files on them... i.e. my back up from August 10th has certain music files that do not exist on my backup from November 10th, as I deleted them from my computer after they were backed up to the external HD. I'd love to be able to see all of my music in one place, rather different versions of my music folder on different days.
    Any help would be greatly appreciated.
    Thanks a lot.

    Hi,
    1. Your Time Machine should should do the full backup of your computer just once and then only diffrences between backups - whenever you plug in the drive.
    If that's not the case something is misconfigured.
    2. You can exclude folders (documents, pictures etc) from being backed up. This is in in Time Machine Options (right bottom corner.
    3. The drive is (most likely) indexed by Spotlight. However, provided those are backup files I would advise against browsing and searching them directly. This can damage the backup itself.
    4. I cannot work out the exact scenario you are using - but the ideal (proper one) would be to have all your music library on your computer and only backup on your external drive. This you should not have to browse and use until you need to restore files.
    5. If you keep your music library solely on the external drive - it should be not in the backup files.
    Also such practice is risky as all drives crash sooner or later and you will lose your music.
    Best would be to keep all music on the computer and backup onto your external drive.
    Or
    if the music library is too big for your computer you may keep it externally - but Isuggest you get one of the external hard dirves with RAID1 or higher. This will keep your music safer lest one of the drives packs up.
    Let me know if you want me to elaborate on any of the aforementioned.

  • Trouble with external hard drive. help.

    I was formatting my hard drive to allow larger GB files with a lot of trouble so I got my other hard drive which I have previously formatted to find the program that worked. It was formatted with NTFS so I downloaded NTFS 3G and restarted my computer (iMac intel) after trying to format my portable hard drive to ntfs the software didnt work so I uninstalled it. Now my external hard drive will not read on my iMac but it will on my TV and Windows computer. When I installed the software a little error message popped up but i made no changes to the external hard drive and now it wont read on my mac.
    The hard drive is a Western Digital My Book 1TB

    Did you read this section of the ntfs 3g website?  I don't use the program but it may have left pieces of itself on your mac causing your current problems.
    You can type the following in a terminal window to see what "non-apple" drivers are still loaded on your system.
    kextstat | grep -v com.apple

  • Migration Assistant with External Hard Drive

    Can the Migration Assistant be used with an external hard drive which has a complete install of OS X on it?
    I am finally upgrading my old iMac for a new iMac. I plan on harvesting the old iMac's 60 GB drive and put it in an external enclosure for added storage. Though the old one's firewire ports work fine, I thought it might be easier to migrate the old iMac's settings from the "new" external drive rather than going through the targeted disk mode and all.
    Thanks for any opinions,

    I did this just yesterday yesterday. I put a new disk into a G4 iMac, installed a fresh copy of Tiger on it and then migrated the user folders across from the old drive that I put in a firewire enclosure. Obviously if you go for an Intel Mac then you will have to be careful with the applications.
