How do you test internal RAID drives?

I've been reading a lot of posts and have learned a lot about RAID setups for the MacPro. Thanks to all. I decided to order 2 500GB WD RE2 hard drives to set up in a RAID 0 config using Apple's software.
I've learned I should zero the drives first. After that, however, is there any software that can be used to check the drives both initially and for maintenance? It is my understanding that Drive Genius does not work with RAID arrays. I don't know that TechTool does either. Is there any software that can or should be used to check or repair RAID arrays?
I thought I had it all figured out but I guess I didn't consider everything before deciding on using a RAID array.
Thanks

Disk Utility works just fine on RAIDs as does TechTool Pro 4.5.2. I've also used Drive Genius 1.5.1 as well without problem. Only one I haven't tried is Disk Warrior 4 because that was just released. As for repairing a broken RAID you need to use Disk Utility.
It is not really necessary to zero the drives (it can't hurt but it is time consuming.) You really only need partition the drives and format them Mac OS Extended (Journaled.) Disk Utility will do that for you without a problem.
BTW, you don't need to make more than one partition, but you do need to go through the initial partitioning process on new drives to be sure they are setup properly for Intel Macs.

How Do You Test a Flash Drive for Errors Using OS X?

HI. In Windows there are Flash Drive tester that tests if there's something wrong with the Flash drive's chips. How do you test a flash drive for errors on OS X? I bought the HP v220w which is tiny for a 16GB and it's metal. The whole thing goes into the plug. Design wise, it is great, it's very elegant like a jewelry. Thanks in advance.
Gbu.

Format it for OS X and run a surface scan on the partition. That should show any hardware problems that don't keep it from working altogether.

How do you know a hard drive is bad?

how do you know a hard drive is bad?

From the OS X "Help" system:
Check whether a disk is about to fail
You can check the health of many disks in Disk Utility. Many disks include Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T) hardware, which lets a disk test itself for potential problems.
Open Disk Utility.
Select the disk in the list at the left.
If you see a message saying the disk has a fatal hardware error, the disk has an irreparable hardware problem that can’t be fixed by Disk Utility or any other utility that repairs software problems. Back up as much of the data on the disk as possible, and then replace the disk.
If you don’t see a message saying the disk has a hardware error but you still have problems with the disk, you can try to repair it with Disk Utility.

How do you test your new laptops?

To the gurus or people who have researched this question: How do you test your new laptops?
When you get a new laptop, what do you do to test it?
My X1Carbon might arrive in a couple weeks, and reading about all the failures and DOAs is scary. So assuming mine is not simply DOA, how do you shake out the less obvious or more obscure problems?
I did search for this info before posting. One other person asked the question,
>> Would appreciate advice re optimal set-up and what testing/diagnostics to do to determine if ther...
but no one answered.

With testing I start with the basics and work my way to the harder stuff.
Inspect the external condition of the machine.
Boot and enter the BIOS before Windows. Review settings then power off.
Boot from Acronis True Image Home backup/recovery DVD and clone HDD or SSD and thus the factory image before it's ever booted to Windows.
Boot to Windows and look carefully at the Lenovo factory image and try to get an understanding for the Lenovo software and why it is there. This does not include the other software from Microsoft, Google, etc.
Create Lenovo Factory Image DVD set with Rescue and Recovery. Throw disk set in the box or put on the shelf in case the machine is ever re-sold.
Test all of the ports - I test every port on the machine for my expected usage. For instance, in the case of the X1 Carbon I would confirm the mini DisplayPort connection works correctly with an external LCD panel. If the machine had a IEEE firewire port or something, test that. Test the USB 3.0 ports with a known working external external enclosure and verify transfer speeds.
Test the SSD speed with CrystalDiskMark, ATTO and AS Disk Benchmark software to get a good overview of the performance.
Install HWiNFO and look carefully at the components. Observe turbo boosting, thermals and fan RPM over the course of a few days for battery and AC power.
Do at least one full battery discharge and recharge. Observe the cycle and details are being properly displayed and recorded in Lenovo Power Manager.
Download all software and drivers from support.lenovo.com for the model being tested. Confirm visually you have all the core components needed. Core includes the drivers, power management driver, Power Manager, hotkeys, etc.
Flatten the machine and install Windows or Linux from scratch. Install drivers and software.
Re-test ports and confirm the machine is working properly.
Benchmark the SSD again. Confirm no change.
Install HWiNFO and confirm turbo, thermals and fan speeds are still proper.
Install core applications and test them. There may be core features in Windows that also need to be installed and tested. For instance, Windows 8 Hyper-V for virtualization.
Connect any external devices you expect to use and test them. For instance, video cameras, smartphones, mp3 players, digital cameras, printers, USB docks, etc.
Do several battery tests with your typical applications and behavior. The goal here is to simulate how the machine will be used in your day-to-day setting or travel scenarios. I usually do at least three tests. This can be rather time consuming with long battery life machines so I get a lot of other testing out of the way first.
By the time you get to this point, if you haven't hit any major roadblocks you'll start to have a good feel for the machine, and if it is going to be a keeper or not. The assumption here is that during this timeframe you have been observing the screen, keyboard, and trackpad performance to see if it's to your liking. The other assumption is that you are using the machine and applications in the scenarios you are purchasing it for.
I don't run synthetic benchmarks. I prefer to test a machine against the scenarios I expect to use it with. I spend most of the first week making this assessment. If any major hardware defects are present, the machine is automatically returned. I do not repair machines just received. No exceptions.
Week 2 is for ironing out any minor issues and assessing if the machine meets the requirements for the scenarios it will support. If it does, it is kept. If it does not, it is returned. This week includes subjective and objective input. You have to weigh the pros and cons for a machine against your priorities. It is rare that a machine is perfect so you have to decide the ROI for the machine. Service and Support must be considered so week two might include a call to support for any unresolved issues. Don't discount the service you receive during this period.
After week two, you are likely right on top of the last day to return a Lenovo machine. The return period is 21 days from the invoice date (I believe), not the day the machine is received so make sure you are well aware of it. After 21 days, the machine is yours for good unless you sell it. Decision time.
Good luck.

How large can an internal hard drive be on a Mac Pro part #ZOD8 ?

Mac Pro tower can support drives up to 4TB is size.
If running 10.8.4, 10.8.5 or 10.9.0, there is a bug in Disk Utility that precludes proper erasing of drives over 2.2TB as Internal drives

WindyCityNorth

Kappy Thanks for help.. I had already tried the Disk Utility but external drive did not show. What worked was to shut down every thing and shut off power to all. Disconnect power to the external drive. Connected power to computer and then restarted the computer. After the computer was up and running, I reconnected power to external drive and then turn it on. At this point the external drive returned to my desk top

HT201737 how do you close a thumb drive that does not show in finder?

How do you close a thumb drive that does not show in finder?

What do you mean by "Close?"
Eject??
If so, you could use Go to Computer to find it if it is not in the Sidebar or on the Desktop. Ctrl-click or Right-click on the drive and choose Eject <diskname>
Or, you could set it to show in the SideBar in the Finder Preferences, SideBar tab. Then, it would have an eject icon next to it in the Sidebar.

How do you test any SAP objects before a transport to the production server

How do you test any SAP objects before a transport to the production server?

Hi Rama Krishna,
The actual process is develop the object in development system and unit test there with the available data.
Then move it to Quality server where the data will be the actual replica of production and where the integration testing and ened to end testing happens and also the user acceptance testing happens there.
and once everything is found fine there then it is moved to production system.
Award points if this is helpful.

How do You Test EMail Connectivity?

How do You Test EMail Connectivity?
Once you setup the mail gateway with an IP address, port, and domain name. How can you test email connectivity? How do you force the MARS Appliance to send an email?

There is no "test e-mail connectivity" button/function. Essentially you need to configure inspection rules to notify you when they are fired by mars.
You will need to setup a user (preferably a non-admin account for testing) under "Management"-"user management"(if you haven't already done so) make sure to supply e-mail address.
http://www.cisco.com/en/US/docs/security/security_management/cs-mars/6.0/initial/configuration/setup.html#wp1030836
Now you can "Configure a Rule to Send an Alert Action." the following link explains how to do this...An easy one would be the "System Rule: CS-MARS Login Failures - Non-Admin User" rule. Follow the instructions in the link below under the "Configure a Rule to Send an Alert Action" section to modify the rule mentioned above. Keep in mind that this rule only fires when there are login failures. Once you have modified this rule try logging into mars using the non-admin user with a bad password...you should get a e-mail from MARS.

Hope this helps.

How do you replace a hard drive on a xserve raid

I am running an old xserve (10.3.9) I need to replace one hard drive in my raid set. I have a new hard drive exactly the same as the one I am replacing. Do I have to do anything in raid admin (version 1.2) or once I insert the new hard drive will it just start working and the other drives will start talking and writing data to it? Thanks for any help!

Hi
Slightly confused about what it is you actually have?
Do you mean an XServe like this one here:
http://www.google.co.uk/imgres?q=XServe&num=10&hl=en&tbo=d&biw=1433&bih=856&tbm= isch&tbnid=VXlw7-KP6nEsaM:&imgrefurl=http://inertz.org/2008/01/xserve-an-impress ive-multitude-of-potential-used-server/&docid=HT9gRAJQrNrS8M&imgurl=http://inert z.org/wp-content/uploads/2008/01/xserveg5.jpg&w=600&h=361&ei=9YPQUI6dLeX-4QTwloC 4Dw&zoom=1&iact=rc&dur=639&sig=102214044775849835144&page=1&tbnh=144&tbnw=242&st art=0&ndsp=35&ved=1t:429,r:3,s:0,i:124&tx=152&ty=81
You can't/don't use RAID Admin on an XServe.
Or do you mean an XServe RAID like this one here:
http://www.google.co.uk/imgres?q=XServe&num=10&hl=en&tbo=d&biw=1433&bih=856&tbm= isch&tbnid=-wl73CtlayTBlM:&imgrefurl=http://en.wikipedia.org/wiki/File:Xserve_RA ID.jpg&docid=9pxrypAvxoLK-M&imgurl=http://upload.wikimedia.org/wikipedia/commons /0/06/Xserve_RAID.jpg&w=1296&h=416&ei=9YPQUI6dLeX-4QTwloC4Dw&zoom=1&iact=hc&vpx= 709&vpy=345&dur=119&hovh=127&hovw=397&tx=170&ty=57&sig=102214044775849835144&pag e=1&tbnh=81&tbnw=252&start=0&ndsp=35&ved=1t:429,r:11,s:0,i:148
If it's the above simply remove the drive module and assuming you have a replacement drive module and drive, insert the new drive module. If you only have the drive, release the plastic moulding at the foot of the removed drive module, release the screws, remove the drive and reverse the process to install the new drive. Insert the module and the rebuild should happen immediately and you can use it normally while all this is happening. Depending on how much data you have stored on the unit, performance loss should be minimal. I would monitor the progress using RAID Admin.
As ever try and make sure you have a full and effective back-up handy just in case.
If it's an XServe you're going to have to provide more information as what you do will depend a little on how the RAID set was created.
HTH?

How to Install New Internal Hard Drive on Mac Pro Laptop

My wifes 15 in Mid 2010 lap top running 10.8.4 has run out of drive space so we bought a new 1tb drive to install. We aren't sure where to go from here. The current contents are back up on Time Machine, but we also bought a small hard drive enclosure to take out the current hard drive and put it in the small enclosure.
So...do we install the new 1tb drive into the laptop and then try and start from the original hard drive that is now in an enclousure...then "Copy" or "Migrate" the material from the original hard drive to the new on? If so...how is that done?
Or do we try and "Copy" or "Migrate" the hard drive materials backed up on Time Machine? If so...how do we do that?
Thank you!

After formatting the new hdd, while still outside the mac, make a clone of your internal disk with CarbonCopyCloner on the new (still external) disk: CCC will ask you to install the Recovery Partition also, do that, and then the clone.
Then you eject the new drive, shutdown, and then you open the mac take the original disk out, and put the new one in.
On the OWC and other sites you will find instructions how to do the switch. Be very careful with the connectors inside .
