Why do my two external hard drives require "ejection" prior to shutdown?

Why do my two external hard drives require "ejection" upon shutdown?

Problem solved. I had plugged in my external hard drives into a USB card.  I switched my two printers to the USB card and plugged in the two hard drives into the computer's USB outlets and now NO improper eject messages. What a relief!!!  Thanks again.

  • HT201250 I have two external hard drives. One is my Time Machine backup drive.  The other I use for external storage of files (documents, photos, movies, etc).  Can I set Time Machine to backup BOTH my Mac hard drive and my other external hard drive?

    Yes you can make multiple backups on one hard drive, for example if you’ve 1TB hard drive installed in your PC and you’ve two Mac Machines with 500GB drive each then you just make two backup images with size of 500GB each.

  • Two external hard drives and Time Machine Problem

    I have two external hard drives I use with Time Machine. One is for constant backup and the other I keep off-site and back up weekly.
    Problem: Each time I connect a different hard drive it wants to start from scratch and create another new backup file. What I want is called smart copy in Superduper! but can't figure out how to do it on Time Machine
    Thank You

    Anybody?

  • Backing up to two external hard drives

    I have two external hard drives - a LaCie FireWire (my first purchase) and a small Targus USB (used while travelling). Backup software is Silverkeeper. I used the LaCie exclusively for about six months with no problems. The initial backup was lengthy but subsequent backups were much quicker, since it was merely an updating process.
    The LaCie stayed at home and the Targus was used for four months. It performed in exactly the same manner.....lengthy on initial backup but quicker on subsequent backups.
    What happens now is that every time I try to do a backup, alternating between the two hard drives, the software indicates that no backup has ever been performed and I must start from "scratch". In addition, I get a window telling me that if I want to create a bootable back-up, the destination volume must be totally blank. (I do realize that only the FireWire drive can be a bootable copy).
    I am totally baffled. Any suggestions?

    Whilst I totally recommend SuperDuper!, and use it myself, be aware that the more advanced features like the fast Smart Backups and scheduling are only available from the full (registered version). The free version will only do a full and complete clone.
    That said I think SD! is well worth the asking price and definitely my primary choice.

  • How do i brig two external hard drives??

    I was told you could brig two external hard drives together. i tried to do so but as soon as i connect them to my computer they shut off, does any one know if it can actually be done, if it can how do you do it? i have two Western Digital ( my books).

    By "bridge" do you mean just connecting two external hard drives to a computer or do you mean a "RAID" system where they operate as one drive with enough info to rebuild the files if one drive fails?
    If you have two unused USB ports on your computer you should be able to connect each drive to a port.

  • Why aren't my external hard drives visible in the Finder?

    I have two external hard drives, both Seagates. I just tried to grab a file from one of them and the dirve isn't visible on the finder. The other is used as my TimeMachine backup and I can open Time Machine. I can't access any files on the other drive by doing a search.
    Any suggestions?

    I was going to try that, but I decided to try what I call the "clown car" solution (I call it that because it doesn't make any logical sense, but it works)--I restarted and all was fine..

    Two external hard drive are not appearing on the desktop anymore on my 2008 24" iMac. One is a Lacie d2 Quadra and the other is a G Drive. Both are 1 Tb

    Are they daisy chained? Have you tried them one at a time? Have you tried a different FireWire cable? Do they show up in either system profiler or Disk Utility? Have you reset the SMC? http://support.apple.com/kb/HT3964

  • Time Machine says both of my external hard drives require reformatting to case insensitive. What do I do?

    I have been successfuly using Time Machine to back my iMac  to an external hard drive (via usb) and everything has been fine for the last year. I have been using TM to back up to a HD called Terra LaCie via usb.
    A week ago, my iMac hard drive was full--so I spulrged and bought a 6 TB external hard drive (Western Digital My Book-Thunderbolt). I set up the new Thunderbold HD to use RAID 1 (mirror) and copied most of my iMac hard drive over to the Thunderbolt HD.
    I kept my working photographs (most recent) on my iMac and felt good to know my older photographs are on my new Thunderbolt hard drive.
    For a few days, Time Machine seemed to work fine (backing up my iMac to Terra LaCie HD. I haven't been concerned with backing up the Thunderbolt drive (as I feel that mirroring is same as backing up).
    Yesterday, Time Machine indicated the lastest back-up failed (for the HD called Terra LaCie). Now, when I go into Time Machine, the dialog box indicates the following message:
    "Are you sure you want to erase the backup disk “Terra Lacie”? Erasing will destroy all information on the disk and can’t be undone.
    The disk must be erased before it can be used for Time Machine backups because a disk you are backing up is case sensitive, but the backup disk is not."
    When I open Time Machine to look at my external hard drives (I also have a third usb portable drive); two of the three drives indicate the following:
    "reformat required; case insensitive disk".
    The small, portable hard drive (that I'm also using) doesn't say it needs to be reformated (but my new Thunderbolt and my old usb HD both indicate the same message (above).
    What should I do? I just spent days transferring my photographs from my iMac to my new Thunderbolt. Should I just not use Time Machine any longer and work from my Thunderbolt drive?
    Am I to understand that my iMac suddenly become case sensitive? Sorry if this was too much information about my hard-ware set-up.
    Any help someone can provide me would be greatly appreciated. I suppose I need to understand Time Machine and perhaps my Thunderbolt better.

    Hi BDAqua,
    Bravo, you helped me solve my problem.
    The Case Sensitive Disk was the small portable hard drive that I was using termporarily.
    I just disconnected it and I started TM machine and everything seems to be working just fine.
    Thank you very much!!!!

  • External Hard Drive requirements needed?

    Hello. I'm very new to Mac...I have an external hard drive from my PC and was wondering what the requirements are to run TimeMachine...I realize that I would have delete everything on the hard drive if I wish to use it. It is a Maxtor. Thank you.

    The size of the TM backup disk should be 2 to 3 times the amount of data you expect to back up. That will leave plenty of room for incremental backups.
    The disk will have to be reformatted with the Mac HFS+ (Journaled) file system. Disk Utility is the tool to use for that.

  • Why won't my external hard drive connect to my mac anymore

    I have a 1 Terabyte external HD that I use for my timemachine back ups.  I eject it whenever I need to use my laptop away from my desk and re-connect it so it will do an automatic back up.  the other day, it would not eject at ALL, so I ended up having to shutdown my laptop and disconnect it.  Later, when I went to reconnect it to the laptop, my Mac doesn't recognize it.  I have rebooted the laptop and the external hard drive multiple times, but when I plug the HD into the laptop, the Mac still doesn't "sense" it.  I can't do any backups at the moment.

    From reading similar threads, and from my own experiences, the prevailing wisdom seems to be that:
    * the drive must be formatted as Mac OS Extended (Journal), not FAT32, NTFS or other
    * the drive must not be currently used as a time machine disk
    * (theory) the drive must not have previously been used a time machine disk
    From my own experiences, I had 3 externals that worked w/ iMovie 11 but not w/ FCP X.  With some experimentation, I was able to confirm the above items.
    - one drive was a TM disk, and just wasn't ever going to work.  Annoying, but at least an identified issue (or bug)
    - one drive was once a TM disk but I'd stopped using it as such.  I'd manually deleted the backups on it, but suspect that TM likely leaves invisble files around to identify meta on file lists, exclusions, etc.  Showing invisibles in finder listed a plethora of files that I wasn't willing to research.  Went into disk utility, formatted as Extended Journaled, and the disk started to appear in project and event windows in FCP X.
    - one drive was formatted as NTFS.  I use Tuxera to read/write NTFS and this seemingly caused no problems in iMovie.  With numerous threads discussing FAT32/NTFS incompatability, I opted to format this disk and then restore my old iMovie events and projects.  Again, this resulted in the drive being visible in FCP X.
    One note, as mentioned above, in the case of the disk wehere I restored old iMovie events/projects, the disk didn't immediately show in the events window (but did show projects immediately).  The solution was to insure that the events window was grouping events by disk.  The default layout hid away my external disk until I did this--and once grouped properly, I was able to then import my iMovie events into FCP X successfully.
    Good luck...the support for exernal drives (and likely NAS) seems really poorly documented.  I lost at least two days to this.

  • I would like to combine two external hard drives into one?  How do I go about doing this?

    Hello:   In iPhoto I have an old external hard drive (EHD) with a photo library and a new one EHD with a photo library which has more space.  I would like to move all the photos from the old EHD to the new EDH.  Can you show me the steps to get this done so I don't lose any of my photos? I just want to use the new EHD only after the move.

    Connect both drives to your mac.
    Quit iPhoto, if it is runinning.
    If both your iPhoto libraries have the same name, rename one of them, perhaps "iPhoto Library 1.photolibrary" and "iPhoto Library 2.photolibrary", so you will not overwrite one of them, when you move them to the same drive.
    Select the library one in the Finder and drag it from the old drive to the new drive.
    Now launch iPhoto while depressing the option (alt) key and selecting the library in the new location. This way you can switch between the libraries.
    If you want to combine the two libraries into one single library, you will need another program. iPhoto Library Manager can merge libraries into one.

  • Why won't my external hard drive appear in Finder?

    I have an Iomega 320GB SPHDU external hard drive which I was using as my backup disk for Time Machine and also to store other files (documents, photos, etc.). I have been using for some time now and never had any problems, however this morning, I plugged the hard drive into my MacBook Pro, which is from early 2011 and on operating system OS X 10.9.4, using the USB ports and the hard drive did not appear in Finder. I checked to see if it had appeared in Disk Utility which it does, but Disk Utility is telling me that the hard drive needs repairing. When I try to repair the hard drive, I get the message 'Disk Utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed up files.' As I said I have never had any problems with it before, but this has just occurred this morning and I'm unsure why it has happened.

    Because there's a problem with the disk's directory structure; these are often the result of improperly unplugging drives or forcing a computer to shut down. Proceed as instructed, or try using a more powerful utility such as DiskWarrior to repair it.
