ALL hard drives-except boot disk-eject during sleep!!!!

Hello all,
I'm looking for a solution so a rather frustrating problem. I'm running Mountain lion (10.8.2) on an early 2009 Mac Pro.
Here is my storage setup:
Boot disk- 60 Gig OWC SSD Mercury Electra connected to the secondary optical slot (Sata II)
Internal Drive bays are all routed through this RAID card, which also necessitates the use of this attachment.
Drive bays are as follows:
Bay 1- Crucial M4 512 gb, 6 gb/s SSD
Bay 2- WD Caviar Black 1tb HDD
Bay 3- WD Caviar Black 1tb HDD **The WD drives are in a hardware Raid 0**
Bay 4- Seagate 1 tb HDD
Additionally, I have this 3tb external enclosure connected connected to the RAID card as well.
Additional notes for any questions about why this setup is how it is: This machine is used for music production (primarily film scores). This necessitates the need for the RAID card for streaming data (music samples) very quickly. The RAID card not only allows a fast hardware raid, but also allows my 6 gb/s SSD to read at full speed (500 mb/s) as opposed to my standard 3 gb/s which my is all my Logic board supports.
SO, the problem occurs when I put the computer to sleep. When it wakes from sleep—every time— all of my hard disks AND external enclosure are ejected from the computer, save the boot disk, of course. The common denominator here is of course the connection to the RAID card, but I'm also reading this happens to peoples exteranl drives very frequently on Mountain Lion as well. Is there any solution out there, or anything you can glean from my setup?
Thanks very much,
R

janne salovaara,
have you tried booting the new disk externally (either by putting it into an external enclosure, or by connecting it with a SATA-to-USB or SATA-to-FireWire adapter, and then using Startup Manager to choose it as the boot volume), to see if that works? If the new disk is bootable externally, but it isn’t bootable internally, that would point to a faulty internal SATA cable — even though it will boot with the old disk. (That slowness of the old disk could also be a symptom of a faulty internal SATA cable.)

Cannot see external hard drive except in disk utility

when i open it in disk utility, all the buttons are grey, and i cannot verify or repair the disk. This happened once i updated it to mavericks.

Hi Dominic,
If this is still not mounting, it may be worth trying a PRAM reset...

Can I install windows 7 on a potable Hard Drive using boot camp? or any other way to do so?? need help for college please

I need to use windows in order to use Visual C++ for college but I don't have enough space in my internal Hard Drive so I want to install windows 7using boot camp or any other method on a portable hard drive and boot from it.
Please help I need it as soon as possible for school. Thanks

You can't boot Windows natively except on internal drives.
You can use a VM and put the VM image (VHD) anywhere any drive you want.
You are way too low on disk space, seriously so. And no room - even Windows and Mac OS should be warning and balking already.
"emulator" is an old-school term, even true, running a Guest OS under Mac's as a virtual machine, shared resources (RAM, processor) is easier but not the same performance level as running natively.

Help with using external hard drive to boot windows on PC

Hi,
I'm not sure if this is in the right place, so apologies in advance if not. I've looked around the internet for a good while now, and I haven't found anyone in my exact position.
My PC's hard drive (running Windows 7) recently died; long story short, I am attempting to reinstall windows. The only other computer I have is this MacBook Pro, on which I have an .iso file of Windows 7. So I want to use my external hard drive (WD 500GB "MyBook") as a boot device so that I can install Windows onto my new internal hard drive.
The problem I am having is that, well, nothing seems to be working. Every time I try to load the .iso onto my external hard drive and boot my PC with it, either a blank screen appears or it says "missing operating system".
I have made sure that the BIOS is running the external hard drive as its boot priority.
I have tried using Disk Utility to partition the external drive, then using 'Restore' to load the .iso onto the partition, to no avail.
I have tried simply dropping the extracted .iso files onto the hard drive, this doesn't work.
I have also tried changing the file system of the external hard drive using the 'Erase' feature (NTFS-3G (using an addon), FAT32, exFAT, all of the others), but I notice that whenever I use Restore after doing this, the file system seems to return to Mac OS Extended, which might be why it isn't booting up on my PC. Is there any way I can succesfully partition the external hard drive in a format that will allow Windows 7 to boot (such as NTFS?), and is Disk Utility even the right program to do this?
If you want any more information from me, please let me know and I'll do my best to provide it - I'm not the most advanced mac user in the world, but I've spent days trying to fix this problem and nothing, no combination of anything, seems to work at all. So any help will be greatly appreciated!
Thanks

Here is a quick suggestion for you:
Download Virtual Box (free PC Emulator for Mac) and install Windows 7 on your Mac (don't worry about activating it yet, as you don't need to keep it more than a few hours). You can tell Virtual Box to use the ISO file as the DVD drive for your virtual Windows computer, so no need to burn a disk.
Search Google for creating a bootable USB installer for Windows 7. I found a link that gave good instructions on how to do this using DiskPart.
Follow the instructions to make the bootable USB stick for installing Windows 7 using your virtual machine you created above.
Use the USB stick to install Windows on your new PC.
Remove the virtual Windows machine from your Mac.
Remove Virtual Box from your Mac.
I found a set of instructions and built an installable USB stick last night that worked great for installing Windows 7 Pro (64 bit) onto my older ThinkPad I had sitting at home. The USB installer also installs in about half the time as a DVD install. The only reason I have you create the virtual Windows PC is that all of the instructions for makeing the Windows install USB stick are written assuming that you already have access to a running Windows PC. By doing this install, you have up to 3 days before you would need to activate it and you can build the installer USB stick and remove teh virtual computer long before that.

Can I install SuSE on an external hard drive and boot to that OS?

Hi,
I'd like to figure out and maybe even keep up with what a friend is doing with linux on a pc.
Can I install SuSE 10.1 on an external Lacie hard drive and boot to that OS by holding down option during start-up?
Thanks,
Garrett

Hi,
I'm an OS X fan who was totally engrossed in the terminal a few years back but became side-tracked into structural and sculptural stuff instead of the computer.
The Mac mini forum mentioned putting OS X on external hard drives to supe up the mini so it made me wonder about other Operating Systems.
Now I'm mostly interested in being a little familiar with the SuSE OS because I heared the Chinese have adopted Linux; my impression is China and Europe are the cultural future and vanguard.
U.S. is the only place on Earth using inches, farenheit, gallons, and pounds, for example. I'm anxious to use software that will come from Europe in the next year or two and China in the next four or five. Most American corps, except Apple, seem to have peaked, to me.
I'm just curious as to what's out there. Anyplace not gone metric yet is SO yesterday. I'll feel way cool when I send my PC friend a screen shot of Linux on my Mac using the external Lacie hard drive instead of an internal partition.

Can I move cache to external hard drive to save disk space for photoshop and bridge?

Can I move cache to external hard drive to save disk space for photoshop and bridge?

So could I take everything off my external hard drive, save it to my Mac, then re-format it for my Mac and move everything back to the external hard drive?
Yes. Keep in mind that you need to back up all data, including the data on an external drive. So if you're going to use the external drive to store original data, as opposed to backups, then you really need another one to back up the first one. You also need to back up the data on your internal drive, of course. This isn't optional. You must do it, or you'll lose everything sooner or later. All disk drives fail eventually, often with no warning.
If I do that how do I format the external hard drive for my Mac?
Launch the Disk Utility application and search the built-in help for "erase."
Would it be easier to just buy a external hard drive that is for a Mac?
All external hard drives work with Macs. Some might come pre-formatted for use with Macs, but it only takes a few minutes to do that yourself.

I'm trying to install OEM SR 2.1: Windows 95B in Qemu... How do I figure out which brand of CD-ROM drive Qemu emulates since I have three different drive specific boot disks...?

I'm trying to install OEM SR 2.1: Windows 95B in Qemu... How do I figure out which brand of CD-ROM drive Qemu emulates since I have three different drive specific boot disks...?

Not exactly...; all MS produced Win9X/ME install CDs are ISO-9660 & maybe even Joliet too... The really confusing part is that not all Windows 98 SE full install CDs are even bootable in the first place (they tend to only ship one if the PC is capable of booting directly from its optical drive...; the vast majority of PCs have to use the chain loading method due to buggy, poorly written, outdated BIOSes...; etc.). OEM SR 2.1/Windows 95B is really quite special & innovative for its time in that it was the first Service Release of Windows 95 to support larger HDs via FAT32 which back then was still brand new: i.e.: exciting technology & it still has proven to be quite useful & versatile since most flash memory storage devices come pre-formatted FAT32.
There's also a hidden X:\Usbsupp folder on the CD that contains the MS USB 1.1 supplement patches/upgrader: a common mis-nomer is that you don't need to install it unless your PC has USB 1.1 ports. Even without USB 1.1 ports the upgrades to C:\Windows\system make it a lot less buggy, more secure & stable. For anyone else that enjoys emulating OEM SR 2.1 there's also a great unofficial SP 1 for it which has so many useful patches in it I'm considering integrating it into all of my install CDs...
Unfortunately I've found that getting it to run decently requires tracking down a bevy of essential but according to MS's not releasing them in patch form optional DLL upgrades... I guess not all machines are that unreliable but better to have them...; just in case you encounter a PC with a buggy BIOS that has hardware coniptions and/or ACPI/APM bugs.

External USB 3 Hard Drive as Scratch Disk

Hi All
Just wondering is it OK to use a External USB 3 500 GB Hard Drive as Scratch Disk. I have USB 3 ports on my PC and have internal hard drive also, but would it be OK to use the external drive as a scratch disk
Thanks in Advance
Ged

Perhaps you could do some benchmarking.
There are programs that can measure your drive's capability, or you can just copy a few big files to it and see how long it takes.
I suggest that if it can't reach a majority of 100 megabytes / second throughput for a sequential read / write, then it is probably not a good candidate.

Creative Licensing Services waking up all hard drives, even offline drives.

I wasn't sure where to post this or report a bug, but these two services seem to have incorrect behavior. They will scan every hard drive in the system, which will wake up every drive in the computer, even if the drives are set to "Offline" in Disk Management.
Creative Audio Engine Licensing Service (CTAELicensing.exe)
Creative ALchemy AL6 Licensing Service (AL6Licensing.exe)
For what purpose do these services need low level drive access to every drive in the system? I have 3 disk drives and an SSD, I like to keep my disk drives turned off for silence, but whenever these two services run, respective programs lag as the computer spins up every hard drive one at a time. I suspect this would happen to external USB drives too.
Here's a performance monitor screenshot of CTAELicensing.exe waking up all hard drives when you click the "encoder" tab of "Creative Audio Control Panel". (for Dolby Digital Live and DTS Connect)
And here's another performance monitor screenshot of AL6Licensing.exe waking up all drives when I launch an ALchemy enabled game.

Forgot to mention, I've seen this happen on Windows 7 x64 and Windows 8 CP x64 on both an X-Fi Titanium HD and a X-Fi Titanium Fatal1ty Pro.

Two drives : same buffer on all hard drives ?

I just ordered a SATA Maxtor drive 300G 7200, Buffer 16Mo (model 6B300S0) to add onto the second bay of my G5 DP 1.8 Ghz.
The original drive (that will be kept in place) is also from Maxtor, 80G 7200, Buffer 8Mo.
I just went by this article from apple support "http://docs.info.apple.com/article.html?artnum=300355".
It says
"Storage :
Two Serial ATA controllers supporting up to 150-MBps data throughput per hard drive
Two 3.5-inch hard drive expansion bays with drive guides for a second drive
One 80GB or 160GB 7200-rpm Serial ATA drive installed in standard configurations(5)
Support for up to two internal Serial ATA drives; 500GB maximum system capacity(5)
8MB memory buffers on all hard drives"
Is this "8MB memory buffers on all drives" restrictive, meaning there might problematic to have two hard drives running with different buffers ?
Thank you for any suggestion, I still have time to cancel my order and order another drive with 8 MB buffer before tomorrow..
Luc

Thank you for your reply,
As a matter of fact, the Apple report is from october 2004, and my machine from April 2005, not much further away. I have found an happy report in XRL8yourmac from sept 2004 describing no problem with the same drive in a Dual 2.5 GHz Power Mac G5 .
The writer says it ran faster than the original 250GB Maxtor 7Y250M0 (8Mo buffer), but did not say if the two drives are running allong well or if he did replace the 250 by the 300. I understood that we cannot instal more than 500 Gig total in a G5 this generation ??
My specific question is :
Is it any reason to think that running two SATA drives with different size buffers would be problematic ?
Many thanks
Luc

Does macbook have to have internal hard drive to boot?!

As i'm having partition problems with the aftermarket hard drive installed in my macbook, I am resigned to re-partitioning it to install SL and restoring from time machine.
However, the old stock hard drive I have is in a caddy, I kept it as a backup incase anything ever goes wrong, then I can just boot straight back into a copy of OSX 10.5, last night I managed to install SL on this drive etc,
So i'm wondering is it possible to boot the macbook from the USB Snow Leopard drive, then at the same time in a seperate caddie, re-partition the other hard drive so I can perform a fresh installation?
Complicated I know, but i've looked into other areas and it appears this is going to be the only way!
Comments, advice and suggestions welcome

I can confirm that the macbook does not need a internal hard drive to boot, I booted using the factory hard drive in a USB caddie, and then installed Snow Leopard via another USB caddie
thanks for the help Matt

Then your iTunes must be looking at the removable disc, not your hard drive. Did you actually copy the songs onto your computer, or simply tell iTunes to look at the removable drive?
Highlight a song and click on File/Get Info/Summary>Where and check the location that iTunes has listed for the song. What does it say?
