Hi,
As RAID is enabled on motherboard, the configuration should be finished in BIOS as well. So the RAID1 should be already configged before installing Windows system.
When boot with an installation CD, you should have an option like "load driver for hard disk" or so. RAID will not be directly recognized so you should use that option to install a driver first.
If it will not work, contact motherboard manufacturer for more support on this function.

What should i do if my external hard drive is not detected by my mac

what should i do if my external hard drive is not detected by my mac?
need to have the files saved on it and be able to backup via time machine

Hi:
Here are some of the options I've read about on here that may or may not work:
1. Reset the NVRAM as it may need to be reset to recognize the drive. See below:
http://support.apple.com/kb/ht1379
2. If the drive is a USB drive, put a USB hub between the drive and the unit. As ridiculous as that may sound in some cases it works.
3. If you have some types of hardware problems and want to test them this works:
http://scsc-online.com/Scannerz.html
That's a test tool only. It isn't going to fix anything just diagnose a bunch of possible hardware problems and it costs money, too.
What format is the drive in? Is it a Mac native format like HFS or is it some other format, like NTFS or FAT?

External hard-drive does not reconnect after sleep

Hi everyone
I am trying to use my Energy Saver to SLEEP my iMac after 1 hour. It goes to sleep no problem, but on wake-up, my external USB hard drive does not reconnect. There is also an error message that I didn't disconnect the drive properly. I fear this may be one of Mac OS X's "features". Has anyone encountered the same thing?
On a side note, I also find that my USB keyboard does not always reconnect as well. I use a windows USB mouse that I have connected to wake it from sleep, however my USB keyboard (the small one for Macs), sometimes does not allow me to type unless I unplug it and back in.
Another point of note is that both the HD and the keyboard are connected to the iMac through a 7 port USB hub.

I think this might be the issue. If the iMac is waking back up, it will likely be waking up this HUB, but the HUB might not be re-initialising the connection between OS X and the external drive or the keyboard.
After waking the iMac, if you unplug the external drive from the HUB, then plug it back in again, does OS X pick it up again? Have you tried plugging the external drive directly into the iMac and then testing what the result is?
If you read back on what you've said, you pointed out that you have a USB mouse that you use to wake the iMac from sleep. Is this mouse directly connected to the iMac? If so, it surely can't be a coincidence that a directly connected USB device can wake the iMac from sleep, but any USB devices connected to the iMac via a USB HUB cannot.
I would suggest you test the drive as it is directly connected to the iMac. I would complete the same test with the keyboard too. I think you'll find it's the USB HUB.
I hope this helps.

External hard drive is not recognized after attempt to format

I just got a new macbook and couldn't use my external hard drive because it was formatted on a PC and only allowed me to read the data. I backed up the data on the 250gb hd and then used Disk Utility to erase the hd and format it as "Mac OS extended (journaled)." After beginning, Disk Utility stopped working and showed up as "not responding" in the Activity Monitor.
Now the hd does not show up on the desktop and can only be seen in Disk Utility. If I try to erase again or partition the hd the utility stops responding. If I try to zero out the drive it continues to say "preparing to zero" indefinately. Now the hd is also not recognized by windows except in the windows disk utility, but it does not even give the option of formatting/initializing it, so that is not an option.
Has anyone ever seen anything like this before, or have any idea of something that I haven't tried yet. I really want to get the drive working and have exhausted all the ideas I can come up with. The internet has not provided too many ideas either.
Thanks so much for your help.
Black MacBook Mac OS X (10.4.6)

I have crazy solution to format it to FAT 32, it work a couple times on my several MAxtor, and Western Digital HD. But this is the last resort and if you are not handy and familiar, don't do it.
It happen on my external HD, so I crack the enclosure open, pulled the HD out and attached it as internal HD on a PC after adjusting the jumper to master and make sure no other HD attached to the motherboard. Make sure the motherboard detected (you can see it from bios menu).
Insert a bootable installer disk before XP ('98, ME, or 2000), and start from there until a promt comes, and type fdisk and you delete the old partition and create a new partition and restart once using the disk still and format it using FAT 32.
After that you put it back to the enclosure, and mount it to MacBook as a new HD with default factory format.
If you don't have the installer disk, this might help :
http://www.bootdisk.com/
But if your maxtor still under warranty better talk to them first and they might willing to reformat it for you.
Hope this help your external back and let you use it on your MacBook.

External hard drive does not mount after sleep

I am using a brand new Seagate 2 TB external hard drive for my backup drive. More often than not, when the computer goes to sleep, the icon for the drive is gone from the desktop when the computer wakes up. I have to unplug it from the computer and reconnect it, then it mounts and works fine. I have it plugged directly into the computer's USB port. The drive uses USB3. As far as I can tell, it does not exceed the power requirements of the USB port. It is the only external hard drive I am using at the moment.
I should note that the same thing was happening with my last hard drive. That was a Western Digital 250 GB drive with an independant power source connected by firewire.
I am running OS 10.6.8 on an Intel circa 2009 iMac. My external drives worked fine for years, and it seems in the last year or so is when this started happening.

Hard drive will not mount after optical drive upgrade

I recently performed an optical drive install. Had to remove the hard drive bays (I use three hard drives - Luckily, 2 run OSX).
I carefully removed all three drive bays and the empty bay. When I inserted the drives into the computer I had changed the position, swapping one OSX drive with a different one and reversing the drive bays. On restart, the computer started on the drive I had not selected for startup and I received an error message stating the other drive could not mount and it gave three options (Initialize - Ignore and Eject).
I can see the drive in Disk Utility and repair the permissions (it's also located in the System Profile).
I tried a few things I read in the community using various Terminal commands but was unsuccessful.
(Let me point out that I recently switched from a PPC G5 to MacPro and swapped the drives from PPC into MacPro and all has been fine until I removed changed their positions in the bays)
Any suggestions/help would be greatly appreciated.

I would recommend you reformat your drives that you brought over, and if possible put in a Firewie case.
Swapping drives will normally not matter but you should use Startup Disk to reset the default after using Option key the first time.
Putting in an optical device shouldn't require removing the drives to get the cage loose and let you put in a 2nd superdirve.
G5 used APM partition map, Intel Macs use EFI and requie GPT/GUID.
A drive with just data should not matter but that is not fool-proof either.
A drive iwth the system from a G5 though can.
During startup the boot process scans all volumes and looks for systems and mountable volumes.
Pull all the drives except the one with OS X that you were using, and put that in bay #1.
I've moved arrays between bays and that never "broke" the array or had trouble mounting and using (even moving to ODD ports).

New 27" iMac ejecting external hard drive and not detecting it consistently

I purchased my iMac from Best Buy two days ago and am wondering if I have a lemon. During the process of transferring files via an external hard drive I have noticed a number of issues. My old 2007 iMac had no problem reading the drive but my new iMac keeps ejecting the disk every couple of minutes. I will get a message in the corner of my computer stating that it was not ejected properly.
At one point, the new iMac would not read the drive at all. I plugged in my iPhone and it detected it at first but eventually ejected it and would not detect it again either, not even to charge it. I restarted the computer and it started detecting the iPhone and the external the drive, but now I am back to getting the same error message. I have tried to repair the disk using disk utility and it does not detect any problems. I also tried using every single usb port.
I would appreciate any suggestions and will be taking it back if it keeps having issues.

Hard Drive Capacity not Changing after moving files

My internal hard drive capacity is shown at 249.58 GB and I only had about 1.97 GB available. I moved 122.89 GB of photos to an external hard drive partition plus many seldom used files and folders (not sure of the MB or GB size). Now my hard drive capacity shows 249.58 GB size with 2.36 GB available.
Having moved more that 122.89 GB off my internal hard, why do I not have at least 122 GB available because I moved the photos to free up that space on my internal hard drive?
How can I regain that space the photos used and/or why can't I regain it?
Thanks for your help and suggestions.
Vernon

After posting the previous message, I remembered that I had not emptied the trash So, that is in the process of happening now since I copied the photos to the external drive and moved them from my internal hd to trash!
I'll check on iPhoto's trash later.
Thanks.

External Hard drive is not detecting

I recently converted my external hard drive from FAT32 to NTFS using the Command Prompt as outlined on your website. Everything was working fine, I copied a 7GB file to it and everything worked. The next day I switched on my PC, I couldn't and still can't
find my external 2TB hard drive by my computer. When I plug it in, it is detected by my computer as an external USB mass storage device, but it doesn't appear in the my computer folder. I can also see it in the device manager and the disk management tab of
the manage settings. The system thinks that the partition is healthy. I just can't seem to access it. Please help. I have about 500 to 800 GB of data on it that I really don't want to lose. Its a Seagate back up plus HDD. It has no switch, it switches
on automatically when you plug in the USB. The light on the HD also turns on, and I can feel the disk working inside when I touch it. Thanks in advance. Any help would be appreciated.
P.S. I am using Windows 7 enterprise N edition on a 64-bit Lenovo tablet, if that helps at all.

PowerBook G4 12" Hard Drive upgrade not detected

Hi,
The original 80GB drive in my 12" PowerBook just died. I had been planning to upgrade anyway so I went out and bought a 320GB WD Scorpio Blue PATA drive. I followed the instructions on iFixIt to change the drive and reassembled the PowerBook. I checked all connectors and I can hear the drive spin up when I turn on the laptop. However, the Leopard install DVD does not detect the new drive. It doesn't show in System Profiler or in Disk Utility. I have verified that the drive works by connecting it via a USB enclosure to my iMac. Am I missing something? Is the 320GB drive compatible with my PB?
Thanks

Given that the HD works fine in an external enclosure but isn't detected at all when mounted internally, I surmise that either (a) you failed to get its flex cable firmly reconnected to the logic board, or to the drive itself, when reassembling it, or (b) you damaged the flex cable itself. Press the connectors very firmly into place, especially the logic board connector, then test again. If that doesn't help, you may want to order a replacement cable and see whether that solves the problem.

Printer and USB hard drive are not detected by TC

Two dys ago I got me TC, I added it to my existing WLAN and startet the initial time machine backup.
Worked fine. I was also able to connect a Windows-Notebook to the TC, using it as an network share.
But I can not see a USB printer (HP PSC 2110) or a USB hard drive, I plugged into the TC.
Even if the printer might not be supported the hard drive should be visible in the air port utility. But there is no furter hard drive listed...
(The hard drive is my former time machine hard drive, OS Extended.)

Use an USB hub with its own power supply. The limitations on the base station's USB port, aside from the fact that it only has one, will still apply.

External Hard Drive does not mount after connecting to airport

Hello,
I tried finding a solution to this problem already, but people that posted were having issues seeing the drive connected to the airport, while I am having the opposite problem.
After I tried connecting my USB drive my new airport extreme and it worked there and I tested speed and whatnot, I disconnected it and plugged it back into my iMac and now it will not show up anywhere, and will only show up when connected to the airport.
Basically I want my drive that was connected to the airport to connect to my mac again because it is not working.

To clarify, when you connect that drive directly to your iMac it doesn't appear on the Desktop? Do you have Finder preferences set (in the General tab) to show "External disks"? Do you see the drive in Disk Utility?

My external hard drive is not detecting in my macbook air.

My Seagate backup plus ext hdd is not showing up on my screen. But, it runs well on my pc. How to fix this issue? Thanks in advance.

I have exactly the same problem. Seagate drive not showing up in finder or disc utility but is working on a pc. I've checked the usb ports and other devices are working when plugged in. This is since I updated to 10.10.3 but I can't restore as the Seagate is used for Time Machine.
