Boot Priority with Raid and Single Drives.

I thought I would share something that I discovered yesterday after struggling to get a Sata Raid array to play nicely with a single sata drive.
Sorry if this is already widely known but I couldn’t find any reference to it.
Setup:
MSI K8N Platinum SLI
2x 160GB Maxtor DM10 Raid0 Array (Windows)
1x 160GB Maxtor DM10 Single Drive (Backup)
The main issue I was having was no matter how I setup the array and what I set as the first boot device windows would always try to boot from the single drive.
The array was set to bootable when it was created, and it set to be the first device under the hard disk boot priority sub menu.
If I tried installing windows with the single drive plugged it would always be seen as C: drive and would copy the boot files here even if I selected D: (array) as install location.
If I tried unplugging the single drive and installing windows, it install and boot correctly from the array.
But as soon as I plugged the single drive back in windows would look for the boot files on it and tell me there was an error and no boot files could be found.
When looking through the bios I noticed a setting called “Extended IDE Drive”, this makes the drive appear as an IDE drive so that there is no need to install the sata driver F6 on install.
Once I set this to No/None the drive disappeared from the bios but after a reboot windows saw the drive correctly and allowed me to install windows to the array which was now correctly drive C:
Once windows was installed, the drive appears under the raid controller same as the array drives.
The drive is fully accessible and working natively with the sata drivers installed.

Yeah, not matter what the HDD order is winxp always tries to boot from the single drive when its plugged in.
Not sure if this only happens to me or if other people have had similar issues.
IDE drivers becomes automatically as 1st HDD. you need to switch them.
have you arranged hard disk boot priority? (not main priority)
have a try to push "F8" or "F11" during post to popup menu, and choice correct HDD to boot from there.

Neer WXP RAID and SSCI driver for my Satellite C650-10K

Does anybody know where I can find the Raid and SSCI driver for my Satellite C650-10K?

Hi buddy,
Are you sure that you need RAID or SCSI (not SSCI) driver for Satellite C650?
As far as I know this model doesnt support such hardware
I think you need drivers for SATA controller. This package is called Intel Storage Manager and can be downloaded on official Toshiba website.
Here is an interesting article about XP installation with SATA drivers:

Anyone having issues sharing a document on Numbers with Yosemite and iCloud drive? I am just getting a connecting to iCloud when I hit share by email but it never does, just keeps spinning

Anyone having issues sharing a document on Numbers with Yosemite and iCloud drive? I am just getting a connecting to iCloud when I hit share by email but it never does, just keeps spinning

Yes, I am having this problem too (although I was sharing via a "copy link" command, not via email). My workaround fix was to log into iCloud.com via Safari and get the share link there.

Windows 7 64bit Raid 1 Data Storage setup with UEFI and 6TB drives

i just bought a GigaByte MB with UEFI bios, 1 SSD 128GB drive for the OS (boot up), and 2 6TB drives for use in a raid 1 setup for the data storage.
I have been able to install win 7 64bit using the UEFI dvd drive. I have been able to define the 6TB mirror via the bios (under the Intel Rapid Storage Technology option) . But when ever i go into windows, and check under Disk Management, i don't
see the raid 1, i see two drives listed for the data, each at 1492 GB. I should be seeing 1 drive at 5.4TB.
note: I have tried re-installing win7 64bit many times to see if i have missed something. When i run setup off uefi dvd drive, i see that drive 1 (of what should be part of the mirror) and drive 2 are listed there at the reported 1492 GB size each.
So it seems that win7 doesn't see that mirror that i created via the bios. So is this a bios setting problem somewhere? i presume on this screen i should see the correct mirror size already.
Also, do i need to install win7 via the uefi dvd if i don't want to boot off those large drives (i just want to boot off the ssd. But when i did try that using a legacy mode, i couldn't later try to create a single large drive for the mirror using
GPT formatting. it just wasn't an option. although the mirror was recognized as 1 drive, but broken into 2TB and 3TB.)
what could i possibly be doing wrong??
Thanks for any help

Thank You Roger. I did call Gigabyte. This is how i solved it with the gigabyte support team.
1. Don't try installing Win7 64bit sp1 and setup RAID at the same time. (even go ahead and unplug those raid drives if you have it plugged in). The OS should be installed first on the boot drive, but make sure the BIOS is already set
to RAID (not AHCI. If you already installed OS under AHCI, you need to reinstall OS. i find this crazy because what if you decide to install raid down the road.. to an existing machine.. you can't do that because of this). Make sure
to install OS with the UEFI dvd drive option (i had done this).
2. Once the OS is installed, install all drivers that come for the Motherboard... That should include intel Raid drivers. (note gigabyte support didn't tell me to do this, but i didn't want to take a chance to have to reinstall OS again or have more problems,
but it makes sense.)
3. Now i have the GA-H97-Gaming 3 mother board, it had Bios F3. I upgraded it to F5 as per support tech.
4. turn off machine, and replug in the two 6TB drives.
5. after reboot, i find out that i no longer see Intel RAPID Storage Technology. (this should have displayed when i set the SATA Mode Selection to RAID before i started all this business... it did under bios F3, but not under F5.. bug?? i think so,
so i plan on letting gigabyte know about this). This is a problem. In Intel RAPID Storage Technology is where you define the RAID in the first place. OK, well after several reboots.. i tried to use CTRL-I to get to intel's interface
rather than that of the gigabyte bios. Voila... i define the Mirror...
6. I am able to boot into OS. I got to Drive Management. I now see 1 6TB drive. I initialize it of course using GPT. Format it. All all looks good now.
Hope this helps someone.. took me enough tries to get it right. I really am bothered about requiring the OS installed in the correct SATA mode just to get RAID working. As i mentioned, you can't change your mind afterwards without reinstalling
OS. Also i couldn't even get the OS setup to start when i had those raid drives plugged in.. so make sure to unplug them.
Best Regards.

Problems with RAID and a Flash USB Drive

I'm attempting to install on a RAID 1 array using just one usb flash drive. Yes, just one. I'm trying out the idea's in this thread: http://bbs.archlinux.org/viewtopic.php?id=64281
Partitioning scheme:
sdb1 -> boot partition
sdb2 -> swap
sdb3 -> raid 1 array -> root
I set the partitiions to type 0xfd (linux raid autodetect) in fdisk (probably not necessary) and created the array with:
mdadm -C /dev/md0 -n 2 -l -b internal missing -W --write-behind /dev/sdb3
I then installed like normal, specifying that I needed usb and raid hooks in mkinitcpio.conf
I added "md=0,/dev/sdb3" as a kernel option in grub's menu.lst, specifying that the md driver should assemble /dev/md0 (my root partition) out of /dev/sdb3 before trying to mount it.
This process was succesful using a partition on my hard drive.
However, using a usb drive causes a kernel panic during boot when trying to mount /dev/md0.
Looking at the messages reveals that before my usb drive was detected, md attempted to create the array, unsuccessfully, as /dev/sdb didn't exist yet. "md: unkown device name /dev/sdb3" or something to that effect.
In mkinitcpio.conf, the usb hook comes before the raid hook, so this shouldn't be happening, should it?

I think rootdelay will not work in that special case, rootdelay makes the system to wait after all the hooks are executed, and you need to wait before executing the raid hook.
I don't know if there is an easy way for that, but one solution is to modify the raid hook to wait for /dev/sdb3 to be created :
- edit /lib/initcpio/hooks/raid, add this before the /bin/mdassemble command :
until [ -e /dev/sdb3 ] ;
do
sleep 1 ;
done
- rebuild your boot images with mkinitcpio (you'll need to chroot to your system)
that should work
PS: someone correct me if I'm wrong, but from what I know, the usb hook does not create your /dev/sdb (if you edit the usb hook, you'll see that it only set rootdelay if it is not yet set). it is the udev daemon, which is launched in the background by the udev hook, and the udev daemon is quite long to create USB device nodes.

Need help with Raid 1 hard-drive replacement

Hello All - I hope someone can help with this.
I have a Raid 1 set-up using two 1Tb external drives (1 Seagate and 1 Lacie) which has been working perfectly - until yesterday that is. I received an error message saying the Raid 1 Set was degraded. On checking I got an error message against the Lacie HDD 'Disk failure'. Following instructions i found on Apple Support i tried to replace the failed drive with a new 1Tb drive - but then got an error message saying that the new drive was too small - on checking the original Seagate Drive reads as 999.86 Gb with the new Drive reading 999.83 Gb. I presume this is to do with formatting of the 2 drives, although one would assume (perhaps naively that as both drives are 1Tb they would be the same size when formatted!!
In light of this I ran 'verify disk' on the Raid 1 Set and this was ok and I am now attempting to rebuild the failed Lacie drive - 10 hours still to go. However even if this works I would want to replace this disk as it is quite old now. The Raid 1 Set is backed up to Time Machine on a separate HDD.
Can anyone suggest a way forward for me to swap out the old drive and replace it with the new drive that I have purchased - I can't see how exchanging this for another make would be any guarantee that the disk would be the same size? I understand that I can't replace the failed drive with a larger drive. The only other way I can see of proceeding is to buy a second new disk (same as I got today) and create a new Raid 1 set and copy everything across.
Thanks in Advance

For an external hard disk drive or other (different) system shared
storage devices to work, they probably should be formatted in a
format seen by both operating systems.
If the WD unit is not seen by Windows computers on your network,
the WD may have been formatted in HFS+ for the Macintosh. That
is OK unless you need a Windows computer to access the same.
The Macintosh can see and use a standard Windows disc format;
so the external drive may need to be reformatted away from HFS+
if that is really what is going on (and archive any data on the suspect
drive elsewhere, since it will be lost to reformatting overwrites)
and then both Mac OS X and Windows should see the files on there.
And Macs set up to run Windows may also see the non-Mac format;
without having to re-boot via BootCamp, if that option is in use.
As to the other question(s) I really have no idea at this point in time.
And since that may be the rub, hopefully someone will follow up here.
Good luck & happy computing!

Anyone else having problem with RAID and iTunes syncing photos in Vista?

Hello,
For whatever reason iTunes can not load some of the photos from C drive. It can do it from D drive, though VERY slow. Both C and D are NTFS system, but C is a RAID 0 drive (implemented by hardware on motherboard, Intel 82801G controller). I just wander if this is something related to iTunes not working correctly with RAID drivers, or is it something else? I should say that ALL other programs and games working fine on this drive.
Thanks for the replies.

The problem is with Windows Vista using the NTFS file system, check out this post for the official solution. This has worked perfectly for me everytime I've tried it:

IMac with SSD and Hard drive very slow startup time

I have a new mid 2011 iMac with a 250gb SSD drive and a 2TB drive. All are from Apple as BTO options. When I first used the iMac my typical startup time from the hardware check chime to desktop was typically 12 seconds. Something, somehow has been changed because now it takes over one minute to boot up from the SSD. After the chime I hear the fans running and also the 2tb drive. After about 20 seconds I hear the hard drive spin down and then after another 20 seconds it starts up again. Once it starts up the boot up sequences contiunes and returns to the desktop. After this the iMac perfprms as normal. I have tried running disk utility from the recovery partition. I have also reinstalled Lion as well from the recovery partition and neither of these change the outcome.
When I first got the iMac I used time machine to restore from a previous machine into the 2tb partition and then went into advanced options in System preferences>Users&Groups to point to my home folder on the 2Tb drive rather than the default one on the SSD. That was working fine until I discovered software problems with both Preview and Textedit where they would not start up with this arangement. I then repointed my home folder to the default one on the SSD which cured this issue with these programmes leaving my data remaining on the 2Tb drive. Since doing this I have had the one minute boot up problem.
Can anyone offer any advice as to how I may overcome this problem and get my iMac back to starting up in twelve seconds from the SSD as it did before. Any help would be appreciated on this topic.
Thanks.

Where do you maintain your Home folder - on the SSD or on the HDD?
If you want to do a clean install (from scratch) then do the following:
Install or Reinstall Lion from Scratch
If possible backup your files to an external drive or second internal drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Erase button and wait until the process has completed.
Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Install button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.
Before you go to the extreme of the above would you do this:
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Just in case your system slowness is due to something eating up CPU time. Oh, and if your system is brand new check the upper right corner of the menubar for a "dot" inside the Spotlight glass. This means Spotlight is indexing the drive. Until it finishes your system will be quite sluggish.

Mac Mini with RAID - 4x USB Drives

I've got an older Mac mini 2007 Core 2 Duo machine that isn't doing much since I got the MacBook so I thought about using it to replace my Windows Server.
I did want to have some form of redundancy attached to this server so I hoped to use 4 USB drives of 4tb capacity. I hoped to use two drives "doubled up" to get the capacity I needed (8tb) and another two to "mirror" the first two for redundancy.
I'm aware that OSX has RAID partitioning available but wondered if what I want to do is possible, has anyone tried this setup?

Thanks both for your thoughts.
I'm now having a rethink myself as USB2 does have limitations I want to avoid, and have come up with options:
A new Mac mini with USB3/Thunderbolt to speed up the throughput (I will be using it to stream HD to Apple TV, for the iPhoto Library and for Time Machine Backups) on which I would use either a Direct Attached Storage solution with RAID 5
or
A standalone NAS box. Is there a NAS that could do all three jobs? I guess it would have to natively format HFS+ because of iPhoto...and have an iTunes server and be Time Machine compatible. A tall order?
Thoughts?

How do I enable booting from CD/DVD and USB drives?

Ok, I have been struggling with this all night, and I am stumped. I have a brand new z510 notebook, and I need to do a clean install of windows 8.1. Problem is that I can't seem to boot from CD or USB. I have entered the bios, and although the DVD rom drive works, and it shown correctly in BIOS, it does NOT allow me to add it to the boot list. Also, there is an option called 'Boot From USB' I enable that, and still the USB boot does not show up in the boot list. The only thing I have in the boot list is the 'Windows Boot Manager' and it lists the name of my drive.
I thought that maybe secure boot was the issue, but I tried disabling this, and is still doesn't let me do what I want.
I am kind of at my wit's end here. I just paid $800 for a top of the line laptop, and I can't even boot from a cdrom. Every computer I have had since the 1980s have allowed me to do just that without trouble.
What am I missing??
Solved!
Go to Solution.

Do you see any BIOS settings like "Boot mode" with a "CSM" or "Legacy" type of item as a choice? You might try toggling that to see if you can successfully boot from external media that way.
Disclaimer: I don't have a Z510 to confirm the BIOS screens. I'm going by inference from what I see on my Y2P and X1C.
Please let me know if this works.
Regards.
Edit: LenBlazer was quicker on the draw.
Please do post back with how things work out.

Blue screen, wont boot up, have checked and verified drives, reset pram/vra

Hi guys, my 3 week old macbook pro has died? Has been fine. Worked last night, shut down, turned on this morning and i got the apple logo grey screen with turning wheel, then a blue screen ... and i have been there all day.
I have used the hardware test (all ok), checked and verified drives (all ok, a couple files were modified not fixed) using the installation disk.
restarted a few times now and the same thing occurs, i cant get passed the blue screen. Using install disk and disk utility i can get to my desktop (very limited access can not really do too much)
does anyone have any ideas? thanks i have none as i have only used mac for about 3 weeks now!!!!

Hi and welcome to Apple Discussions...
a couple files were modified not fixed) using the installation disk.
Try booting from your install disc again. Sometimes it takes more than one pass.
Insert your install disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
While you have the Disk Utility window open, look at the bottom of the window. Where you see Capacity and Available. *Make sure there is always 10% to 15% free disk space*
If Disk Utility reports errors but cannot repair them, take your MBPro to an Apple store or Apple certified repair provider as it's obviously still under warranty.

Install RAID and SAS drives in my Mac Pro

Hello,
I have a couple of Mac Pro machines and I want to install extra drives.
I want to install 2 extra SAS 300GB drives.
I take it I need to install a RAID card also.
Will the drives connect to the RAID?
I don't want them to mirror I simply want them as single drives that I can use for storage.
My main concern is will I be able to mouint and access these SAS RAID drives without having to reinstall the OSX System?
Thanks,
Dean

Not quiet sure I follow your plan here.
I want to install 2 extra SAS 300GB drives.
OK, no problem, assuming you have 2 spare bays.
I take it I need to install a RAID card also.
OK, no problem there, either, assuming you have a spare slot.
Will the drives connect to the RAID?
Umm, if you connect them, yes. It doesn't happen automatically
I don't want them to mirror I simply want them as single drives that I can use for storage.
This is what I don't understand - why use the RAID card if you're not planning on RAIDing the drives?
My main concern is will I be able to mouint and access these SAS RAID drives without having to reinstall the OSX System?
If these are additional drives it won't affect the existing system at all. They're completely separate.
If, on the other hand, you want to take the existing system and move it to a RAID volume then yes, you'll need to do some kind of work to preserve your data, but it's not clear that's what you're trying to do.

Problem with Installer and DVD drive

I am having problems with my dvd combo drive reading discs. It keeps spitting them out. More importantly, I am trying to load Adobe Illustrator CS2 and cannot get all the wat through the installation proccess. Is there a patch I am not aware of??

You could be looking at some kind of driver corruption issue (say if that sector on your hd had gone bad, or the file was dorked somehow). Have you done repaired permissions on the hd recently?
Do all types of DVDs fail -- music, movies, and apps? If some work and others do not, then it could be a problem with a particular app.
It never hurts to check the cables. Insufficient data or power can cause all kinds of problems.
