Activating TRIM feature on RAIDed drives?

Hi Apple community.
I have 4 Samsung SSD 840 series drives in my bay. One I use as system. The other (3) are RAIDed via software raid. I recently downloaded both Chameleon SSd Optomizer and TrimEnabler. (still not sure which I will use yet) to ENABLE trim feature on my Mac Pro.
My question is: Should I enable the trim on all drives or just the sytem drive?
TIA

you leave out a critical item and what and why they are used.
most use 3-4 SSDs for scratch editing, even CS6 still uses scratch.
many would put them on two PCIe controllers like Sonnet Tempo Pro SSD which is $300 which gets you near 2GB/sec fast I/O and speeds up editing large files.
And the size of the devices. 240GB are better, more queue depth.
RAID should all be same size of course and firmware etc.
Intel motherboards and controllers do not support TRIM in RAID environment though they have been looking into it and some beta drivers for ages it has not happened. And anyone doing so I would say is taking a risk.
But you always need to be prepared with SSD to restore
Data seems to do better than when used as a system too.
And having TRIM might have one value: having it on your maintenance boot drive so you can run Disk Utilty and let it invoke TRIM command.
TRIM is or was suppose to be part of the SATA 3.x specification and rolled into the SATA Native Command Queue instruction set.
SSDs have to me probably been one of the most complex and the development and evolution longer than I ever expected, with new features often breaking and causing more work and testing at each stage. Personally. It was summer '08 we began to see Intel X25 and OWC and others and start using them in our Macs, it was not until very end of 2010 the SandForce 2.0 firmware and when I jumped in. And now SF is often pointed to as if they are not reliable (though Intel customizes and as an OEM has to do more testing and R&D than anyone).
Two years ago, May 2011 era, was when SATA3 SSDs firmware was in a heap of trouble and messy soup.

Activating TRIM on external SSD drive

Hi, I just purchased a Samsung 850 EVO SSD to use as an external cache for After Effects. However, I've been having some issues and am wondering whether this could be related to the trim setting. I am not using the SSD as a boot drive, merely as and external drive so with that in mind, should I activate TRIM and if so, how would I go about that without affecting the kext signing on my internal boot drive?
Many thanks

You can do it with

However, you still have to disable kext signing since trim is in the OS even if not used by the boot drive

Problem Installing HP Officejet J4580 Full Feature Software and Driver

Hallo !
I recently installed a new 2T harddrive and performed a clean install of Windows 7 Home Premium 64-bit on my e-Machine Model ET-1331-g-05w. The clean install of Windows 7, installation of the e-Machine drivers, und 325+ Microsoft Updates was successful. The System is running fine and protected by Kaspersky 2015 Internet Security. Please note this WAS NOT an OS upgrade from Vista to Win7 - just a clean-install of the original Win7 64-bit OS.
After creating an ISO and Full Backup(nothing else has been installed at this point) I wan't to re-install my HP Officejet J4580 All-in-one. I have the original CD but I know that it can only be used on an XP or Vista OS - so I went to the www3.hp.Offical HP Drivers and Support downloaded the Product Installation Software for:
HP Officejet Full Feature Software and Driver
File: OJJ4500_FULL_13.exe
Released: 2014-09-03
Version: 13.0.0
My printer wasn't connected via USB - the install ran for about 30 and when I asked to connect the USB cable the splash screen told me it was finishing the install but then it failed with a message unable to located J4580 Drivers. The install that place the Solution Center, HP Document Manager, and HP Photosmart ICON's on my Desktop - when I opened the Solution Center - it said that it couldn't communicate to the printer. The printer and USB cable work fine on my Vista Desktop, my Vista Business Notbook. and my IBM X40 running WP SP3.
I've also tried running:
1) HP Update Software Utility - hpsetup.exe
2) Hp Print and Scan Doctor - HPPSdr.exe
3) HP Officejet Software and Driver Removal Utility - OJJ4500_Scrubber_13.exe
but the 2nd attempt to re-install failed too.
I then reloaded my clean ISO - and tried the Product Installation Software for the Basic Drivers
HP Officejet Basic Print and Scan Driver
File: OJJ4500_Basic_13.exe
Released: 2014-09-03
Version: 13.0.0
The Basic Drivers worked fine -but I need the Full Driver. I double checked and the WIN 7 64-bit is shown as a supported OS for the Full Driver - any suggestions on how to proceed? I'm wondering if it would be worthwhile installing XP virtual machine and installing the Full Drivers in VM. If I go that route - it creates other issues such as sync'n file from 64-bit to VM, then switching back & forth between VM to process other work, and then the issue of having to scan in VM then sync the folder to 64-bit side.

Hello @Tom_Ma,
Welcome to the HP Support Forums!
I would like to assist you today with installing your HP Officejet J4580 All-in-One Printer on your Windows 7 computer. Thank you for including all of the troubleshooting steps you have already attempted and your Operating System details in your post. At this point I am going to run you through some additional troubleshooting steps to get this Officejet successfully installed with the Full Feature driver. Please follow the steps below.
Step 1: Uninstall Drivers:
It is important that we have a nice clean slate to work with for troubleshooting. Therefore, I am going to have you uninstall the existing software on your computer.
Click on your Start menu
Select All Programs
Select the HP folder
Select your HP Officejet
Select Uninstall
Follow the onscreen instructions to complete the uninstall of your printer. Once the uninstall is complete, please proceed to the next step.
Step 2: Clear Temp Files:
Click on your Start menu
In the 'search programs and files' box located right above Start after you click on it, type %temp% and hit enter on your keyboard
When the Temp folder opens, select Ctrl + A at the same time on your keyboard. Everything in this folder will now highlight.
Select the 'delete' button on your keyboard. The Temp folder contains temporary internet files. No actual files or folders on your computer will be affected by deleting the Temp files. Should a Temp file still be used than you will automatically get the pop up to 'skip' that item.
Close the Temp folder once it is emptied
Right click the Recycling Bin on your desktop and select Empty Recycling Bin
Step 3: Unlock System Administrator Account:
There is the potential that there is something within your User Account that may be blocking the drivers from installing properly. Therefore, I am going to have you unlock the hidden System Administrator Account and install your device under there. Then, when you log back into your normal User Account the printer and all Full Feature software should be installed and functional for you. If all goes well, we we 'hide' the System Administrator Account once troubleshooting is complete.
Go to your Start menu and under the 'search programs and files' box type CMD
CMD will populate as a search option above, just right click on it and 'run as administrator'
Once CMD (Command Prompt) opens, type net user administrator /active:yes and hit enter
Next, close CMD and restart your computer
When your computer comes on log into the new account that should show. It will be called Administrator and will not have a password on it.
If your computer automatically logs into your account after restart than go to your start menu click the arrow beside 'shutdown' and choose 'switch user'. Now log into the Administrator account we just unlocked
Under the Administrator account download and install the drivers: HP Officejet Full Feature Software and Driver
Please follow the onscreen instructions to complete the installation of your printer
Once the installation is complete, please test printing and scanning to confirm that everything is now working properly.
If everything installs fine, log out of this account and back into your normal User Account. All the Software and Drivers for your product should show installed now on your account.
Under your User Account please test printing and scanning again to confirm that everything is still working.
If everything works fine, you will want to Hide the Administrator account.
Step 4: Hide System Administrator Account:
Go to your Start menu and under the 'search programs and files' box type CMD
CMD will populate as a search option above, just right click on it and 'run as administrator'
Once CMD (Command Prompt) opens, type net user administrator /active:no and hit enter
Next, close CMD and restart your computer

Qosmio G30 - Question about the Raid driver

Do i actually need this driver to use RAID? If its set in BIOS, what does the driver actually do? apart from give you health stats?
Cheers

Yes, you need the RAID driver.
I think The Qosmio G30 was designed with the RAID feature like some G20 units.
Without this RAID driver you will be not able to install the OS because the OS setup cannot recognize the HDD.
The RAID uses two options:
RAID-0 (Striping): two HDDs are used as one big drive, if one HDD fails all data is lost
RAID-1 (Mirroring): both HDDs contain the same data, if one drive fails data is not lost
I think you could check this posting and additionally use the forum advanced search for more results about RAID.

RAID drive not loading up

Hello,
On Thursday, I upgraded my op to Tiger 10.4.4 from Panther and then installed the new universal FCP Studio software package. Until then, we had no problems with our Huge Systems SCCI RAID drive. Now, the drive won't even load up upon clicking on its icon on the desktop. What do I need to do to fix this issue?
Thanks,
Jordan

HI Jordan,
Click a clear space on your Desktop. Then click Finder/Preferences/General. Make sure the first 3 tabs are checked and see if that helps.
Also, run Disk Utility from Applications/Utilities and Repair Disk Permissions.
Also, depending on the size of the internal disk, a good thing to remember is your Mac needs 15-20% free disk space just to boot. Mounting peripherals takes space also... to view this information open Disk Utility, select MacintoshHD in the panel on the left, then look at the bottom right side of the window where it says: Capacity and Available. You can also see this information using the Activity Monitor. Always a good idea when working with large files to keep an eye on available disk space.

Assistance Making Arch RAID Driver from Source - LSI MegaRAID 9240-4i

Hey all-
I've been on Arch for about 6 months now and love it. However, I just built out a new workstation and need some assistance trying to get my RAID card up and running. Obviously, Arch Linux isn't going to be officially supported by any manufacturer, so I went with a card that fit the price and feature set I wanted and decided I'll do battle later. Later is now and I'm a little stuck. Here's what I have and know:
First, I went to http://www.lsi.com/storage_home/product … index.html and looked at the different drivers they had source code for. I decided that the Slackware driver is probably the best place to start since rpms and debs are more distro-specific and since between the other two Slackware is more current than Scientific. I have downloaded and extracted the source for the Slack driver and am in that directory with a dkms.conf, Makefile, megaraid_sas.c, megaraid_sas.h, and Module.supported in it, along with two folders worth of patches and the like.
My understanding is that since this driver isn't going to be available in the Arch Build System, I should follow the guide at http://wiki.archlinux.org/index.php/Creating_Packages to make a PKGBUILD. However, to be fair, I haven't coded since my C++ in college and it's been a while. Specifically, I am lost at the "Download and test the installation" heading. How am I to test the installation? I'm on an Arch box right now and the whole point of this was to get something I could successfully install on Arch.
Ouside of being lost there, I assume that when this all finishes, I will have some module package either megaraid_sas.o or megaraid_sas.ko that I can drop into my install and set to load via rc.conf.
If anyone has any light they can shed on this subject, please reply. If you need more info from me, please say so, so I can provide it. I tried to at least give a solid overview in my initial post.
-Ryan

for future reference : the linux kernel supports many raid controllers (adaptec, areca, lsi meagraid sata etc ) check kernel source for details.
I recommend you add a non-raid drive to the megaraid system, and install arch on that drive.
Edit : Dieter says exactly what i wanted to say
Dieter@be wrote:Afaik the megaraid will write metadata on that disk. So you loose some flexibility, say when your controller breaks. I have my arch install on a disk which is connected to my motherboard directly. (without raid etc)
Next you should create your own pkgbuild .
This Aur pkgbuild for a highpoint sata raid controller (made by me sometime ago) should help you with writing your own : http://aur.archlinux.org/packages.php?ID=12865
once you have built the package, use pacman -U to install it.
modprobe the megaraid_sas module .
check dmesg and/or /dev to see if your raid drives are now detected.
if they are, you can start mounting/accessing/testing the functionality of your raid drives.
Note : it is possible to install archlinux on drives that require an external kernel module, but that makes the process a lot more complicated.

Trim Support in RAID 0 on a P55-GD65

I have some confusion regarding TRIM support in RAID 0. I have 2x80 GB Intel X-25M G2 SSDs in RAID 0 on a P55-GD65 mobo. I am not using a RAID card, and my OS is Windows 7 Ultimate x64. I just flashed the latest firmware update for the drives. According to the Intel SSD Toolbox, TRIM is not enabled. I have the latest Intel Chipset Drivers from Intel's site rather then the MSI downloads center. After doing some reading it sounds like if I back up my data, set the drives to ACHI rather then RAID, rebuild the array, and restore my back up, the drive will support TRIM. Is that correct?

If I am not mistaken, "TRIM" is generally a no-go in RAID-Mode conigurations.

Partitioning a new laptop's RAID drive for scratch disc

I've now set my heart on getting a laptop. I'm doing to much on my old desktop, and getting a laptop is hopefully going to ease the burden & open up some possibilities. Certainly the specs will way better.
I'm seriously thinking about getting a Sony VAIO AR71ZU.
http://vaio.sony.co.uk/view/ShowProduct.action?product=VGN-AR71ZU&site=voe_en_GB_cons&cate gory=VN+AR+Series&assetid=1218032875460
It has a lot f features I like & has 4GB of RAM. Unfortunately it's Vista (Ultimate), but that's what things are coming with now, so that's that.
It has 640GB of HDD space:
Hard Drive Type Serial ATA RAID 0 (0 and 1 supported) 2x320GB
Hard Drive Capacity (GB) 640
Hard Drive Speed (rpm) 5400
The two 320 GB drives look are joined -"con.... something" ! sorry I've forgotten the name for this- the opposite of partitioning. Hence it the drives are seen as one drive. Well for Photoshop one wants a second drive for scratch disc purposes doesn't one. Can I partition this 640GB (320+320GB) drive ? Anyone out there know ? Is it an ok thing to do ?
[One of the added features is "HDD recovery (hidden partition)". I assume this is the backup /recovery facility that comes with Vista Ultimate ? Anyway, it may be of note, as it mentions "hidden partition. Would this interfere with any partitioning ? ]
If I can partition then would it be wise to go for three partitions: one as the main program drive; one for most documents & files; and one for back-up/ other stuff including for use as first scratch disc ?
Anyone wise?
Any advice greatly appreciated.
[I'm also been looking at the possibility of an Alienware laptop, but really I'd rather put that money elsewhere. (Eventually a new desktop but not yet.)]

Thanks, most informative.
I'm considering an Alienware laptop.(Though, expensive!) One can have the double RAID drive, and there is something called SMART BAY which bascially is 3rd drive. Maybe this is a way around things- perhaps get that & make that for the scratch disc...an expensive way around things!

Raid Driver Update..

MSI released a new Raid Driver for my 990FXA-GD80, the older ver. is from 2009.. if I'm remembering correctly.
Can I update the driver version without a restore? Possibly using 'Repair'?
Thanks

xmad..
I'm running perfectly.. but, seeing an update (none for years).. I am curious if there is a benefit, or what the update features are. The older Raid driver installed now, was released before the surge of SSD use. So, like a Bios update.. should I, shouldn't I is the question?
Thanks,
Have a great New Years

Does mountain lion support install from a RAID drive?

does mountain lion support install from a RAID drive?

Apple does not support the 3rd party drives. To enable it (without installing another software package), you can visit the website:
http://digitaldj.net/2011/07/21/trim-enabler-for-lion/
I ran the series of commands on my Mac Pro and it did enable TRIM.
the webpage even has a backup/back-out procedure.
Without TRIM, my computer was running extremely slowly. After enabling TRIM, my computer ran substancially faster.

Unable to capture to external RAID drive FCP 7

Here are my specs:
Model Identifier: MacPro1,1
Processor Name: Dual-Core Intel Xeon
Processor Speed: 2.66 GHz
Number Of Processors: 2
Total Number Of Cores: 4
L2 Cache (per processor): 4 MB
Memory: 4 GB
Bus Speed: 1.33 GHz
Boot ROM Version: MP11.005C.B08
Running:
OS X 10.5.8
Final Cut Studio 3 (recently upgraded from Studio 1)
At the end of last year I had a problem with capturing and upon research it seemed to be that the most recent update of QuickTime was not compatible with Final Cut Pro 5, which was causing my machine to not be able to capture at all. So we upgraded to Final Cut Studio 3 (FCP7) and part of the problem was solved but an issue still remains.
For over 3 years we have been using an external Raid drive as a capture scratch and we still have over 5 TBs free. The Raid is connected by SCSI. Earlier last year I was able to capture to the Raid drive without any problems but now the capture will freeze whenever that is set as the capture scratch. If I set the internal drive as the capture scratch it captures without any issues.
The problem is that using the internal as the capture scratch can only be a short term solution. The drive is only so large and I have a problem with finder if I try to move files from the internal drive to the external. Finder freezes up and I can't even force quit properly. So being able to once again use the external as the main capture scratch is the only real solution. The external is fully functionally and communicating with the Mac.
Any help with resolving this would be appreciated!

Off the top of my head, because I haven't worked with SCSI in years--
"The problem is that using the internal as the capture scratch can only be a short term solution. The drive is only so large and I have a problem with finder if I try to move files from the internal drive to the external. Finder freezes up and I can't even force quit properly. So being able to once again use the external as the main capture scratch is the only real solution. The external is fully functionally and communicating with the Mac."
Are you trying to move files while you have FCP open? The fact that simply moving files is giving you finder issues and freezing you up, says that all is not well with the scsi raid. You should not see that at all.
You might try powering down the mac and the raid, unplugging and letting the machine sit for a while to discharge the capacitors. Then try reseating the scsi card. (pull it out carefully and plug it back in.)
On another note, when you upgraded fcp, did you do a clean install?

Multiple users on single computer mounting same RAID drive

Hi I'm a newbie:)
I have multiple users on a single computer which need to mount the same RAID drive on a different networked computer. I have no problem making the mounts, the only thing is that when each user makes its mount the drive appears multiple times when doing an ls /Volumes. Ie, the first user mounts sparkle and it appears as sparkle. The second user mounts sparkle and it appears as sparkle-1. The third user mounts sparkle and it appears as sparkle-2. In the finder they all show up as just plain sparkle, but for running scripts, the hyphen-# screws things up. Does anyone know of a way to have the same drive mounted without the hyphen-#s?
Many thanks!
Megan

What kind of scripts? I don't think there's any way around the naming problem, but you could use regular expressions. I don't see why sparkle* shouldn't do the trick, or add sparkle-[0-9$] to whatever constuct you have.

Using a expresscard FW800; G-Raid drive unmounts on it's own

I'm using a NitroAV Fw800 dual expresscard to connect my 500gig G-Raid drive that i use for video editing. I have never had a problem with it using Tiger.
Ever since I upgraded to leopard it is behaving strangely.
I mount the drive and all is well, (this is an example of the problem I'm having with it) I used the drive to provide 3.8 gigs of info to burn a disk recently. It burned fine and when it was done the drive just sat there, turned on, mounted for a few minutes and then it unmounts itself.
When it's doing something it behaves fine, when I leave it alone for a bit it unmounts itself and I get the error saying that it has been removed without ejecting it first.
If I connect it via the built in FW400 port, it stays connected and I have no issues. other drive I have are FW400 and they behave perfectly.
I have never had this problem before. what could it be?

I spoke with the company that manufactures the expresscard (NitroAV) again and they said it is a foul up associated with upgrading to Leopard and not installing fresh and reformatting the hard-drive.
Has anyone else had this problem?
Is there anyway to have Apple address this problem?
thanks for any help.

No longer have permissons to RAID drive

Hi. I was able to create a 1TB Raid and store all of my info. Now, however, I cannot access the drive. I can see the folders and files, but when I try to open them I get a "This operation could not be completed. Unexpected error occurred (error code -43)." Under sharing and permissons, I can only "read." There is no lock button to unlock and for me to change the permissons. I can also no longer add new files to the RAID drive.
Under the disc utitiliy it has it lised at RAID Set, online, but with a lock button under each slice.
Raid Set Name: StorageRAID
Volume Format Mac OS Extended (Journaled)
RAID Type: Mirrored RAID Set
Any help would be greatly appreciated.

By the way, I cannot view the RAID in my windows bootcamp either. I can see the drives under computer management, but they are listed as status "Healthy (GPT Protective Partition)."
They also say they have 100% free space, which should not be the case. OS X at least notices 200GB is used.

Want to make sure I replace RAID drive correctly.

In my previous post, I mentioned I had a drive go out and now my system will crash whenever I start my G5 while the fibre channel cables are connected. I'm assuming this is because it automatically mounts the Xserve RAID drive. When I disconnect the fibre cables, it starts up fine and I can go into the RAID admin and see the system and administer it.
Today I got my replacement drive. I've been reading a ton but some re-assurance that I'm doing it correctly would be great. If I've read everything correctly, I should be able to just install the new drive without risk but, if I read everything correctly, I will need to go into the RAID admin utilities and select "make drive available for use" and make the new one the backup?
There is something about "unmounting" the RAID first but it's not mounted or connected by the fibre channel at this time. How/should I do something else to disconnect it? Will it continue to crash my machine at restart or how do I connect it and not have it mount?
Help please
Bart

+I should be able to just install the new drive without risk but, if I read everything correctly, I will need to go into the RAID admin utilities and select "make drive available for use" and make the new one the backup?+
Depending on how the RAID sees the disk it may or may not use it right away. Essentially if it suspects it might be part of another RAID it will not use it until you go into RAID Admin and mark it "available for use". Other than that step it should immediately use the new drive to rebuild the RAID.
+There is something about "unmounting" the RAID first but it's not mounted or connected by the fibre channel at this time. How/should I do something else to disconnect it?+
No, that's talking about unmounting it from the desktop - but with your fibre detached you don't have anything to worry about there.
+Will it continue to crash my machine at restart or how do I connect it and not have it mount?+
I would powerdown the Xserve, attach the cables and then reboot it to be safe. But I wouldn't go so far as to restart the XRAID (unless someone else here with more experience suggests that you do).
Assuming the malformed disk was the source of the crashing hopefully everything will return to normal.
Good luck, let us know how it goes!
