RAID 1 Hard Drives resync after normal shutdown and unplug from wall socket

Hi,
Apologies if this is posted in the wrong Forum Category. Please guide me to the right one.
I have a Raid 1 on two disks on my machine.
If I shut down the system or restart everything runs smoothly. All disks (in Disk Management) are listed as healthy.
However, if I run the normal shut down process, and wait until the computer completely shuts down, and then unplug the computer from the wall socket, the disks have to resync the next time the computer is booted up again.
I don't understand why this is happening, since the change (of unplugging the computer from the wall) happened while it is turned off.
Any help in finding a solution would be greatly appreciated.
Thank you,
Simon

Hello Simon,
Do you mean that after completely shut down and unplug the power?
If you don’t unplug, does this issue exists?
If yes, it may be caused by the hardware issue, please contact the manufacturer to check.
Please make sure you have completely shut down the computer before the unplug. There are no fans running or LED light.
Best regards,

  • Extrnal drive in after a shutdown and it came up a different letter. Now Lightroom does not recognize any of my photos..

    I plugged  my external drive in after removing it to clean the computer. HP PC. When I plugged the external drive in again the drive letter changed and Lightroom could not find any of my photos 11,000 or so of them. I have tried the usual recommendations of locating etc and nothing has worked. The only thing I can do is load them one sub folder at a time. What is the easiest way to re locate all of my photos. No one so far has an answer, only the easy recommended ones which have not worked for me.Please help, i am soo frustrated have spend all afternoon trying things to no avail. If you haven't already guessed, I am not very computer literate

    . Can I simple "Import them" back into Lightroom?
    No
    It is very disappointing that Lightroom can be so adversly affected by simply disconnecting tlhlen reconnecting a  drive.The computert runs much better, by the way, now that it is relatively dust free.
    It should be a simple fix. But if you start moving things in Lightroom instead of changing the drive letter, it becomes less simple.

  • I have a new MacBook Pro, it has a small hard drive, can I plug an extra Hard Drive into my time capsule and access from my Macbook?

    I have saved my itunes Library to an exteranal drive, can I plug that drive into my Time Capsule and tell my itunes to access the music from there?

    Yes, but it's probably better to keep it connected directly to the computer.

  • Hard drive glitches after battery replacement... normal?

    Hello, I have a 4Gen 20gig ipod with click wheel and I just replaced the battery myself last night.
    I then plugged it into my computer to sync and it was recognized by windows, but not by iTunes, the hard drive would whir, then click and then try again, then stop. I figured it was just that the battery wasn't charged enough yet, so I let it charge overnight.
    In the morning it synced fine. I was then playing it in the car, and some songs would appear, then the hard drive would whir, click a couple of times, then skip on to the next one. After a couple songs it started playing them normal. After skipping a few and the hard drive spun to load more music into the temporary memory, it would whir, click and then skip the song, then whir click and skip that one too... and it kept doing it. Then I reset it, and it kept showing the apple symbol, then the Exclamation and folder icon, then tried restarting again. After trying to reset itself 4 or 5 times, it finally succeeded.
    I read a few threads on here, gave the ipod a gentle nudge on the right hand corner a few times, and now its playing and I haven't had any symptoms yet for about an hour.
    Is this normal for a hard drive on an iPod to glitch after a battery replacement? I had no such problems when I had the other battery in it, so it's hard to believe that the hard drive is going bad exactly at the same time I changed batteries. It is the right battery for the right iPod, anyone else experience this or have any words of wisdom or comfort?

    Pretty fast and non-stop, even when I'm not working. Could it be dirty? Is there a way to clean it?
    Does the Apple store charge just to look at something?
    Even if the noise was a dirty hard drive you can't clean the innards of one. You cannot even open one. Well you can, once.

  • G-Raid external hard drive won't mount -- have tried almost everything!

    My iMac (Intel , OSX 10.4.11) has been happily working with my G-Raid external hard drive for over a year. But now, after the computer cord was disconnected yesterday, it refuses to mount the G-Raid or recognize it anywhere. Can't find it in the Disk Utilities or under "About this mac -- Firewire." Called Apple service and tried everything the agent recommended...PRAM diagnostic reboot, power surge, plugging, unplugging...nothing helped. The problem isn't with the G-Raid, which works fine plugged into my old Powerbook with the same firewire. Grateful for any help, as I really need the G-Raid -- it's got all my projects, music, photos....

    Can you plug it in with a USB cable on your iMac? That might get you through your crisis and even resurrect your Firewire connection. Accidentally breaking the connection on my external Firewire drives happens too often as the connector doesn't make a snug fit compared to USB. It's not a problem unless there was something in your buffers at the time the connection was broken. You may need to Repair the drive using Disk Utility when it eventually reconnects or all may be well without more intervention.

  • After replacing the hard drive on my G4 Powerbook and reinstalling Tiger I am no longer able to synch between itunes and itunes, it seems that the software on the ipod is of later date than itunes and I am unable to update itunes to the state prior..

    After replacing the hard drive on my G4 Powerbook and reinstalling Tiger I am no longer able to synch between itunes and my ipod (Classic 160gb) it would seem that the software on the ipod is of later date than itunes and I am unable to update itunes to the state prior to the original harddrive's failure for Tiger OSX 10.4.11
    Any ideas on the subject would be most helpful
    Thanks in advance

    The last security update released for Tiger users was the 2009-005 update. The latest version of QuickTime is 7.6.4. The last version of iTunes that can run on Tiger is 9.2.1, because 10.0 only supports Mac OS X Leopard and later.
    So, are you on version 9.2.1?
    Was it Tiger or Leopard you had on the drive before?

  • Regain hard drive space after deleting partition

    Hello all,
    I had a lot of issues after updating to Snow Leopard so I ended up doing a clean install of SL rather than the update to fix all the issues. It works great now with no lag or any issues of the sort. However I was following a tutorial on how to do the clean install and it had me first partition the hard drive then install. Later I went to erase the old partition of the hard drive and now I cannot regain the space with the new partition. (P.S. sorry if I am not explaining this well.)
    Here is a picture showing my issue. 30 gb of my hard drive is just greyed out and I cannot figure out how to recover that.
    Thank you guys if you can help me resolve this!

    I don't think you can without starting from scratch and re-partitioning the drive with 1 partition.
    Had the unused space been at the bottom of the window, I understand you could have dragged the divider down to regain the space, however it doesn't work dragging the top up.

  • Shared hard drive disappearing after airport update

    My shared hard drive attached to my airport extreme will mount but afterwards gives me the error message "The alias “xxxxxx” can’t be opened because the original item can’t be found." Also the drive is listed under my shared section in the finder window but when selected gives a share-point icon and doesn't allow access. This has been occurring after the airport utility update. Any information would be greatly appreciated....and I just got the access via the internet working and now this - bummer.
    workaround: I have found that selecting the drive in the finder window then deselecting and selecting a second time will give me access to the drive but thats a pain in the rear.

    "It will not let me verify the drive" means that I am unable to verify the drive.
    Today, I installed the security update on my 24" intel imac, that I've owned since April. I restarted the machine. Up came the folder icon with the question mark. I restarted a second time and the same thing occurred. I then inserted the installer disc that came with the computer and I was able to start up the computer that way. Using the Disc Utility, I attempted to verify or repair the hard drive, but all those options were ghosted ("it will not let me verify the hard drive") Also, while there, I saw that the hard drive partitions were not recognized: there were two partitions (1: 500GB; 2: 198GB) but now it was registering a single drive at 698GB of 750.
    I then called Apple support. We reset the PRAM. We did a hard drive test (restart holding "d") and that test produced no error. We then tried unplugging all peripherals, including the power supply, and letting it sit for a few moments. The imac restarted to the same results. Finally, the tech suggested attempting an archive install, which was not available as an option. Further, the install disc did not detect an available hard drive for installation, so the option to reinstall the OS was not an option, either.
    The tech said my only option is to take it in for service, leaving me unable to work for four to five days (if I'm lucky), as they won't get to it until Monday, and even then they're backed up.

  • After installing a new hard drive can I install snow leopard directly from snow leopard disc

    After installing a new hard drive can I install snow leopard directly from snow leopard disc. Or do I have to install previous versions first. iMac 7.1 (2007) 2.8ghz

    You can install directly, assuming the disk is newer than your computer and not designed for a different Mac, but doing so won't install iLife.

  • New Macbook Pro hard drive crash after 9 months?  How to avoid it again...?

    Hi - I've just had my hard drive replaced after it crashed - only after 9 months!!!!  How can this be?  I thought Macs were supposed to be more resilient and reliable?   I always kept the software up to date.
    Is there anything I should be doing to avoid this happening again?  
    - let the battery run down completely / always keep it charged and power source plugged in?
    - don't run too many programmes at once?
    - shut down completely rather than sleep mode?
    If anyone has any tips / advice...otherwise I'm considering selling it.
    Thanks

    You can't just take that drive from the older system and install it in the new system. Even though both run Lion the Lion install on the older system does not have the correct driver set for the new hardware. In fact Apple came out with a newer version of Lion Just For these Newer System.
    It may now be on the Apple servers bot it wasn't a few days, 5-12, ago..

  • Use my G Raid Thunderbolt Hard Drive in Bootcamp

    I have a 4 TB G Raid with Thunderbolt hard drive that I would like to access from my bootcamped Windows 7 half of my Mac. Some googling showed that it needs to be plugged in at startup for thunderbolt to work and that it should install the neccessary drivers. It hasn't installed the drivers and I'm fairly certain that everything is plugged in as it should be as the extra monitor that is daisy-chained through the hard drive does work. Does anyone know where I can find the drivers or where in the device manager I would find the hard drive?

    Have you tried it without the extra Monitor connected?

  • I am trying to open space in my macbook hard drive, so I deleted files and after emptying the trash bin the amount of Gigs didn't increase, why? Where can I go and delete those files?

    I am trying to open space in my macbook hard drive, so I deleted files and after emptying the trash bin the amount of Gigs didn't increase, why? Where can I go and delete those files?

    Did you do a secure empty trash? SHIFT COMMAND DELETE, they will be over wriiten. Are you deleting docs as they aren't much space, videos,pictures,music use much more space.
    You can move those fiels to an external "archive" drive to save them then delete them from your internal drive.
