IMac, 10.9.4, 'drive cannot be read by this computer' message

Just installed Mavericks. 10.9.4. Older WD FW drives--no problems.
New WD USB drives-- messages at startup: 'this drive cannot be read by this computer'
i can click either Eject or Ignore. If I hit Ignore, the drives mount and appear to be normal
and I can copy files to them. At least until they eject themselves. I've followed the other threads about the ejecting
drives, but have not seen anything re these messages I get at startup. What can I do to fix this?

Found a fix for two of the new drives:
Deleted MacKeeper
Deleted all WD files, downloaded WD's Support for Drivers, supposed to help with Mavericks, then deleted it
Reformated both drives
After checking my new WD 4 T drive in Disk Utility and finding either drive was ok or it was damaged and couldn't be repaired, I decide to erase and reformat. Totally surprised to see that the original format was FAT. I reformatted to Mac, extended journaled, and so far I can copy files to the drive easily and much faster than before.
Feel really unintelligent for not confirming the format first! I'm usually way more competent than that!
No wonder the drive couldn't be read by my iMac.

DSP4 Cannot be installed on this computer message??

trying to install dvdsp4 but it comes up with the following msg
DSP4 Cannot be installed on this computer. This computer does not meet the requirements to install this software.
im on 10.4.4 with qt 7.0.4 - final cut studio requires this so dont see where the problem lies, just going to re-insert dvd and try again and again i guess ..

What computer and which version of DVD SP 4?
Both can be in play here
Is it Final Cut Studio or Final Cut Studio 2? The newer versions of DVD SP 4 needs 10.4.9 and QT 7.1.6

Loading CD results in "The disk you inserted cannot be read by this computer".

I have an external Blu-Ray/DVD/CD player/burner which works fine on computer A. However, on computer B, whenever I load a commercial audio CD, I get "The disk you inserted is not readable on this computer". Movie DVDs work fine. DVDs in general work fine. Writeable CDs are fine. Commercial audio CDs will not load. The error in diskarbitrationd log is "Unable to probe \disk\disk04 Status code: 0x0000000B". The computer in question is an iMac from 2011. The computer it works fine on is an iMac from 2012. These two computers have the same configuration; just different purchase dates.
Other, information: It all worked fine on Day 1. I installed Adobe Illustrator CS6 on Day 2, and it immediately didn't work any more. There was a Lexar drive in a USB slot, but I removed it, looked through the extensions for offending files and reset the SMC.
Any ideas will be appreciated.

From what you are explaining it sounds like you need to go into System Preferences and select CD/DVD and make sure you have to play when you insert a commercial CD, While you are there you might want to double check all of your settings.

"The disk inserted cannot be read by this computer"

I have a LaCie Big Disk Extreme (1TB), which has worked fine for me for a few months now, but after trying to get it to work in Windows, I think I might have accidentally reformatted the drive, but I'm not certain. Right now, Windows is telling me that the partition style is 'GPT' or GUID Partition Table. The drive shows up in Disk Utility, but I am not able to repair it.
I need a way to get the drive to show up in Mac OS X again, without having to reformat the drive.

Well, the drive is partitioned properly or so it appears but I would suggest you do the following:
Extended Hard Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. 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 Partition tab in the DU main window.
3. Set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
This should assure that the drive will work correctly with OS X. I'm assuming this is the end result you want.

IMac G5 (Ambient Light Sensor):Mac OS X cannot be instlled on this computer

I have 3 iMac G5's identical specs. They will not install OS X 10.5, but they ran 10.4.11 just fine.
Specs: iMac G5 PowerMac8,2
CPU Type: PowerPC G5 (3.0)
CPU Speed: 1.8 GHz
Memory: 1 GB 2x 512MB PC 3200U-30300
DVD+R (dual layer) 5x read
- DVD±RW 5x read
- DVD±R 6x read
- DVD-ROM 8x read
This fits into the spec required to install OS X 10.5. However, when I attempt to boot from the install disk, erase local disk, erase and format disk using the disk utility, Mac OS extended, Apple Partition Map. I receive message Mac OS X cannot be installed on this computer. At one time I received a message Kernel Panic CPU 0 driver cannot be found for this computer.
I also attempted to install from external DVD±RW DL (non super drive) boots, loads the installer, then same error message. If you need more information ask? Any insight would be appreciated.

As should be obvious by now, your problem is caused by using a model-specific grey installer disk with another Mac model. Not only will it cause technical problems because is it not designed for this purpose, it is a violation of the license that comes with the Mac to use its disks to install the OS or other included software on another Mac.
You must obtain a retail copy of Leopard to install that OS on your iMac G5. You must have a license for each Mac you install it on, either the license that comes with that OS pre-installed on a Mac or the one that comes with the retail copy of the DVD.*
Also note that the grey disks for each Mac you own should be retained, as they include installers for the bundled software that comes with it & a model-specific Apple Hardware Test ("AHT") that must be run from that disk. You cannot easily duplicate the grey disks, in part because the AHT partition is not a conventional boot volume & a disk image file of the entire DVD must be written in a specific way to the duplicate to work like the original.
However, even if you manage to do this, the duplicate still cannot be used with another model, so the only reason to make a duplicate of a grey disk is as a backup for the original.
\* A site license or bulk license also meets this requirement, but you still must obtain a suitable installer disk.

The grey discs will only install on the model of Mac with which they shipped. If these discs didn't ship with your Mac, and they don't work with your Mac, well then there's not much you can do.
As far as it being legal or not, it is illegal to install this software on more than one Mac at the same time. If the original owner of these grey discs is no longer using the software and has removed the software from his system, and he has not retained other copies of it, then it is legal for him to transfer ownership of the software to you, and legal for you to use it. But that's not of much help to you if you don't have the correct model of Mac.
Get the black retail Tiger install disc from amazon.com or elsewhere. It will work on all Mac models with built-in firewire.

Changed out the hard drive in my imac mid 2007 intel. Once the disc loads, I get "Mac OS X cannot be installed on this computer." Help! Be gentle. I am truly a novice. Thanks in advance.

I changed the hard drive in my mid 2007 Intel Imac. I'm trying to re-install the the op system. I'm receiving a message stating that "Mac OS X cannot be installed on this computer." I am a "newbe" to Mac's. Can someone help? Please be gentle. I raeally am a novice. Thanks in advance

I believe these are the wrong system restore discs for your model iMac, assuming your are correct that you have mid 2007 iMac.
These gray colored type restore discs are Mac-machine specific and are the wrong ones for your iMac.
They will not work.
The original OS X restore discs for your model iMac would either install OS X 10.4.11 Tiger or OS X 10.5 Leopard.
You have gray system restore discs for a later model iMac. These will not work with iMac year and model.
Sorry.
You need to purchase a full retail version of OS X 10.6.3 Snow Leopard here instead.
http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
These discs will work with your year and model iMac.
Assuming that your hard drive was installed properly, these white retail OS X install discs should be able to boot, format and install OS X 10.6 Snow Leopard to your 2007 iMac.
Good Luck!

How to reinstall Mac os x 10.5.6 to my imac desktop 24 inch all in one i put in disk and held c down and it came to a message saying os x cannot be installed on this computer HELP?

I understand, while you may have knowledge with PCs you don't have the diagnostic tools available to you to professionaly diagnose a Mac. Apple does not make those tools available for the general public, they are only available to Apple and AASPs. To install the OS on the machine you need to locate the original 10.5.x install disc that shipped with the machine and insert it into the SuperDrive. Below are Apples instructions for setting up the machine:
Turn on the computer.
Insert the Mac OS X Install DVD into the optical drive, or insert the MacBook Air Software Reinstall Drive into the USB port.
Restart the computer.
Press and hold the "C" key while the computer starts up. The computer will start up using the Install media. Alternatively, press and hold the Option key at startup to select the volume containing the installer.
If your are using a wireless mouse, a mouse icon should appear asking you to turn the mouse on so that the computer can discover it.
Select a language, then press the right arrow key.
Click the Utilities menu, the choose Disk Utility.
Select a volume to erase (usually called Macintosh HD).
Click the Erase tab.
Click Erase... Important: This step will completely erase your hard drive. If you have installed Microsoft Windows using Boot Camp, or have multiple partitions, this procedure will erase the partition you select.
A dialog box appears asking if you want to erase the partition: click Erase.
After the partition is erased, choose Quit Disk Utility from the Disk Utility menu.
Part Two: Installing the operating system
When the Mac OS X Snow Leopard Installer screen appears, click Continue.
When the license agreement appears, click Agree.
Select the disk you erased. It should now be highlighted with a green arrow.
Click Install. A status bar appears on the bottom of the screen while Mac OS X installs.
An Additional Information screen appears, advising you that you operating system has been installed. Click Continue.
An Install Succeeded screen appears. Click Restart.
Part Three: Completing the Mac OS X Setup Assistant
When the restart has completed, a welcome video plays, then country/region selection screen appears.
Select your country or region and click Continue.
Select a keyboard layout and click Continue.
A migration screen appears. If you wish to migrate your data from another Macintosh, see Migration tips and tricks. If you do not wish to migrate, or want to migrate later, select "Do not transfer my information now" and click Continue.
A Wireless Service screen appears if you have wireless services available within range of your computer. Select "On" and click Continue.
If the network is password protected, you be asked for a password when you select it. Type the password and click Continue.
An Apple ID screen appears. This is used to purchase content from the iTunes store. When complete, click Continue.
If you do not have an Apple ID, click Continue to move to the next screen.
A Registration Information screen appears. You are not required to fill this out, but it is helpful if you do. When complete, click Continue and your product registration will be sent immediately.
If Mac OS X servers are available on your network, you'll be asked if you'd like to log on to them. If not, click Continue.
A Create Your Account screen appears. This will be used to create a User Account with Login ID and Password for you computer. You should remember this password. You'll be asked for it when you install new software or perform other administrative tasks on your computer. When complete, click Continue and your account will be created immediately.
A screen to select your user picture appears. Take a snapshot with the built-in camera or select a picture from your Library. When complete, click Continue.
A MobileMe screen appears. Select an option and click Continue.
A Thank You screen appears. Click Go to complete the Mac OS X Setup Assistant.
Eject the Mac OS X Install DVD by dragging its icon to the Trash.
Good luck.

IMac says This Software Cannot Be Installed On This Computer

My iMac has just had a new HDD fitted and im trying to re install 10.4 on it and it comes up with "ALERT - This Software Cannot Be Installed On This Computer" what can i do?

1) You must use the either Original Tiger Install DVD set or a later Retail Upgrade Disc than came with that iMac?
2) The Partition Map Scheme of most off the shelf drives is normally Master Boot Record and it must also be changed to GUID Partition Table.
1. Boot from your install DVD, Upgrade Disc or Bootable Clone and open Disk Utility.
2. Highlight the new HD in the list of drives and select the Partition tab.
3. Under Volume Scheme select 1 Partition and click on the Options... button.
4. Select GUID Partition Table in the drop down window and click OK.
5. Set the Format to Mac OS Extended (Journaled) and click the Apply button.
6. Once thats done then you can do a clean Install, Restore your Bootable Clone.

"Mac OS X cannot be installed on this computer." New Hard Drive.

I have just bought a new Seagate Hard Drive and I want to install Mac OS X 10.5 on it. My MacBook is from the days of Tiger, but I have since upgraded to Leopard using the upgrade discs that Apple gave out.
My next door neighbor has a brand new MacBook, so I borrowed her "Mac OS X Install Disc 1" which has a lovely copy of 10.5.2 on it. I put the drive into my computer and partitioned a Mac OS X Volume (Journaled).
THE PROBLEM:
When I then try to boot from the Install Disc 1 and install Leopard, the computer says "Mac OS X cannot be installed on this computer."
Need a solution. Thanks in advance.
PS - I would use my install discs but they are at home in another part of the country.

Well, Apple would probably point out that what you are trying to do violates the EULA.
Technically speaking, however, the issue is that the install/restore DVDs that ship with Macs do not carry all the drivers, or even all of the various versions of libraries that support all of the various models of Macs. The come-with-your-Mac disks are different than the retail versions of the OS (also, the come-with-your-Mac ones bundle iLife, which the retail ones don't).
Because the come-with-your-Mac disk contains only the drivers specific to that generation and model line of Mac, it contains a stub of code that verifies that your hardware matches the driver set on the install/restore DVD.
Your friend has a different model of Mac, with different hardware, so her install/restore disk won't work in yours. Solution: go get the retail boxed version of Leopard.

To me it looks like your undotbs on node3 is filled and not marking old undo as expired. Use this query to find out if it is labeling old undo as expired.
SELECT tablespace_name, status, COUNT(*) AS HOW_MANY
FROM dba_undo_extents
GROUP BY tablespace_name, status;
Another thing I noticed from your alertlog is it is only doing that on undotbs3, which I assumes is on node3.
1) try recreate undotbs on node3
2) take node3 out of service (stop nodeapps, ASM, instance and finally CRS on node3) and see if you can do DML on your database.

Hi,
Our SAP system is down. When checked I found PSAPUNDO tablespace needs recovery. (From SYSSMU1$ to SYSSMU10$ NEEDS RECOVERY and SYSSMU11$ to SYSSMU17$ are offline).
So I have created another tablespace PSAPUNDO2 and altered the system.
SQL >create undo tablespace PSAPUNDO2 datafile 'D:\Oracle\SOL\sapdata1\undo_2\UNDO.DATA2' size 700MB;
SQL>alter system set undo_tablespace=PSAPUNDO2 scope=spfile;
I have changed undo_management to Manual. And I have not dropped old tablespace PSAPUNDO yet,
I have restarted the system and initially the database was not open.
I gave command alter database open and opened it.
The oracle has been started normally. But still SAP instance cannot be started.

In BRTOOLS, in show tablespace command I cannot see the new tablespace PSAPUNDO2.
Kindly suggest how to resolve this issue.

Hi,
Thanks for your reply. When I checked SAP down issue(around 6th Dec) I had exteneded the tablespace PSAPUNO and PSAPSR3 with brtools and restarted the server.
Then I checked further and found the problem was PSAPUNDO needs recovery.
Then I created another tablespace PSAPUNDO2 and altered system. (See my previous post).
Now as you told I checked alert log history to check when the problem started and found the following:

I am not sure what caused this error: ORA-00376: file 2 cannot be read at this time
I think there is no issue with Parallel_Max_Server as I can see its entry in Alert log since 2007.

Will wait for your reply.

Hi
If you have created a new TEMP Tablespace and dropped the old temp tablespace , then you will have to use the follwoing command to make use of the old temp files in the new temporary tablespace.
alter tablespace <new temp tbs name > add tempfile '<old tempfile name>' reuse;
To autoextend the tempfile :
alter database tempfile '<tenpfile name>' autoextend on;
