My iMac Yosemite does not recognise my new WD Elements external hard disk

Does Yosemite include drivers for the WD Elements external hard drive?

Several questions:
Can it be seen in Disk Utility (applications - utilities - disk utility)?
Has it been formatted to Mac OS Extended (Journaled)?
Where are you looking to see if it can be seen by OS X?
Please answer all three questions.

Hey there mbarikiwa,
If your iMac still has not recognized the usb modem, I would use the troubleshooting for Yosemite USB issues in the following article:
OS X Yosemite: If a USB device isn’t working
If the device is connected to a USB hub:
Make sure the device and the hub are the same speed. Connect USB 3.0 SuperSpeed devices to a USB 3.0 SuperSpeed HUB, USB 2.0 Hi-Speed devices to a USB 2.0 Hi-Speed hub, and so on.
If the device doesn’t have a power cord and is plugged into another USB device that doesn’t have a power cord:
Try plugging the device directly into your computer’s USB port or into a USB device that does have a power cord. You might need to disconnect and reconnect the other device as well, if it has stopped responding.
If you have many devices connected to your Mac:
Disconnect all USB devices except the device you’re testing, an Apple keyboard, and an Apple mouse. Make sure that the device is connected directly to the computer, and that any hubs or extension cables are disconnected. If you can use the device now, the problem may be with one of the other USB devices or hubs you had connected to your computer. Try reconnecting them, one by one, to your computer. When you find the device causing the problem, review its documentation for further troubleshooting steps.
Verify that the device appears in System Information:
Choose Apple menu > About This Mac. In the window that appears, click Overview, then click the System Report button to open System Information.
In the window that appears, see if the USB device is listed below Hardware in the Contents list. If the device appears but does not work, review the device’s documentation for further troubleshooting steps.
Restart apps:
Quit and restart any apps that use the device.
Restart your Mac:
Choose Apple menu > Restart.
Check your device’s USB connection
Thank you for using Apple Support Communities.
All the very best,
Sterling

TS1541 imac will does not recognise my password or username

My iMac does not recognise my password or username. have installed the Mac OS X disc that came with the computer and put in place a new password and username, this worked for a day and has now shut me out again? I dont want to have to reinstall the OS X disc again. What are my options?

The most common reason for this is caps lock. Check that it has not been activated.
Is it a wired keyboard or wireless?
Use the install disk to change the password - details:

Not able to delete file from external hard disk

I connected my external hard disk to my macbook pro. But am not able to delete any file since it says the file cannot be deleted when I move it to trash. Could you let me know how to delete a file from the external hard disk?

How is your HDD formatted? NTFS? FAT?
Did you write files with rights? When you strike +I on any file, you can see its rights; if you're read-only, you may change your file's rights.

I had to change my Apple ID and my phone does not recognise my new id.

I had to change my Apple ID since I've gotten my iphone 4s. My computer recognises my "new account" but my phone does not. This poses a problem when I have app updates and the password promt has my OLD apple id and not the new one. Anyone have any ideas with what can fix this? Thanks!!! =-)

No need to double post.
Again, as stated, apps are FOREVER tied to the AppleID under which they were purchased. If you change your AppleID, the apps purchased on the old AppleID will NOT work. If you want to keep your new AppleID, you will have to purchase all those apps again, or else you'll need to keep changing your AppleID on your phone back and forth.

IMac G5 does not recognise datawrite +R DL

iMac G5 2.0 with Tiger and latest software update with DVD PIONEER DVD-RW DVR-K04L and firmware Revision D441.
I place the DVD in the slot and it the Mac is obviously trying to read it but the it ejects it. The display does not even show an icon on the desktop. I have checked the internet but have found no help. Any ideas? Thanks in advance

First, and forgive me if this is a dumb question on my part, I presume you're certain your iMac has a dual-layer capable SuperDrive? Only the last generation of iMac G5, introduced in May of 2005, had a dual-layer SuperDrive.
But if you know for sure that your iMac has a dual-layer drive, you might just try a different brand of media. Some brands work better in some drives than others. Otherwise, if you don't get an answer here, try asking in the iMac G5 area. This forum is for the new Intel-based iMac and so perhaps not the most likely place for you to get a quick and accurate response.
Good luck.

Auto focus in Safari Yosemite does not work on new tab.

Creating a new tab in Safari does not auto focus the address bar. I need to Cmd-L to activate the address bar. This is annoying because I usually create a new tab to enter a search. Is this a bug or working as intended?

OK! I've found the error by myself. The XML file I am trying to update is not schema valid. Infact I've registered the schema with this call:
begin
dbms_xmlschema.registerSchema(
'PurchaseOrder.xsd',
getdocument('PurchaseOrder.xsd'),
TRUE,TRUE,FALSE,TRUE
end;
So the first three lines of the XML file must be:
<PurchaseOrder
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="PurchaseOrder.xsd">
and not
<PurchaseOrder
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="HTTP://localhost/sys/schemas/REF5/PurchaseOrder.xsd">
I think it is better not to register the schema with relative URL...
Bye!

MacBook Pro is not recognising my WD my passport external Hard drive

PLEASE PLEASE HELP
I have 200GB+ of data on my HDD and I DO NOT WAT TO FORMAT IT
I partitioned my WD my passport external Hard drive on Mac through Disk Utility
i then plugged it in to a windows XP computer
and when it did'nt recognise it i went to
right click My copmuter > Manage > Disk management > then i right clicked on the hard drive's name > convert to GPT disk
i though by doing that windows will recognise it .. it didnt
BUT .. when i reconnected it to my mac thats what i got
it still shows in my disk utility but all the options are greyed out
PLEASE if someone knows a way to fix this i'd really appreciate if you would tell me
i have really important documents on that hard drive
Thanks you in advance

I have fears that you data may be gone.
Did you try to see if you could access data on the Windows PC?
I am not versed in Windows but based on the steps you describe suggests that you formatted the disk and erased it. What you might try is to look for recovery software and see if there is anything to salvage.
Ciao.

HP Pavilion Elite e9120y bios does not recognize any cd/dvd/bluray or hard disk drives

I erased my hard disk to install Windows 7. Now my computer intermittently does not recognize that there are any drives attached to the sata ports. I go into BIOS pressing F10 and it does not list any drives at all. I have a DVD burner and a bluray and a western digital 1TB hard drive connected. Sometimes they show that they are connected other times it doesn't. It's strange.
When it does recognize there are drives connected, I boot up from the Windows 7 DVD. Then I try to create a partition on the hard drive. The installation recognizes a 930GB hard drive with no partitions. Every time I try to create a partition, it says I need a driver for the hard drive. I have a driver that I downloaded off of HP's website yesterday, the driver for nvidia sata. I put it on my usb drive. It recognizes it but says it is the wrong driver. I don't know what else to do. I have built dozens of computer and repaired hundreds, but I have never run across a problem like this and I hope you can help me.

Thanks for your help, but that's exactly the driver I used. It didn't work.
My problem is not just with the hard drive. All three drives (two optical, one hard disk) should show up in bios, whether or not there is a disk in the optical drive or a partition on the hard drive. It intermittently stops detecting the drives. One time I boot and go into BIOS they are there, and I can run installation of Windows (partially). But if a turn off the computer and turn it back on, they've disappeared. Sometimes they will be detected, sometimes they won't.
I'm thinking the driver problem with the Windows 7 Professional x64 installation is somehow connected to the drives randomly not showing up. All drives stop showing up at the same time, not just the hard drive. So it's not a driver issue. It has to be connected to the BIOS and motherboard.
This computer is only 4 months out of warranty.
Any more help would be appreciated.

Upgrade to Mavericks does not allow connection to my Lacie external hard drive

I have updated my OS to Mavericks and since then I cannot connect to my external hard drive (Lacie Network Space 2) using my MacBook. I have tried with a PC running windows 7 and it works. Is there anything that I can do?

Hello Sir Gudo,
Thank you for the details of the issue you are experiencing with your external hard drive. I found an article with steps you can take when an external device is not being recognized.
I recommend following the steps in the section titled "Top troubleshooting tips" in the following article:

MUSIC IS ON A EXTERNAL HARD DRIVE NUT DOES NOT IMPORT, MUSIC IS ON A EXTERNAL HARD DRIVE NUT DOES NOT IMPORT

Hi, am after some guidance please. Had to buy a new PC, all my music was on an external hard drive. I am trying to import the music into the library but in the majority of cases instead of pressing the 'play' button on the folder in the external hard drive and the music transfers, the music doesn't import & I am having to sit here clicking on every single track for it to transfer. Am totalaly bored & fed up with this laborious task. Can anyone assist please? Many thanks.

Please ignore previous information posted in error....
If you don't have your original library files then you should be able to add the media folder into a new library using File > Add Folder to Library...

My Macbook Pro mid 2012 is not reading/connecting to my (working)external hard disk(also not showing in disk utility)

I connected my 500GB Storjet external hard drive to my mac(Mountain Lion) http://in.transcend-info.com/products/Catlist.asp?modno=325 but it is not connecting to it. Disk Utility is also not showing it. and the hard disk is working... My PS3, My Sony TV and my other laptop(win7) is detecting it... Also whenever it gets connected a blue light blinks, but It doesnt for mac. I have tried reformatting to both FAT32 and NTFS... Please help..
Also I sorta screwed my Mac so I had to do the internet recovery thing and only after that such problems occured, it was working fine before. So it installed Lion first and then Mountain Lion. It wasn't working on any of the OS.

Power down the Mac, Full power off. Connect the drive using the Y cable and then turn the Mac back on.
If it still doesn't show in at least Disk Utility then start checking your USB ports to see if both are working properly. Just plug in a USB thumb drive and that should show in both Finder and Disk Utility. If one of the ports isn't seeing the thumb drive then that port is bad and the system needs to be services by Apple.

My new iMac does not recognise an iso image of windows install disk in boot camp

I have the iso file for win7 64bit but when I run bootcamp I do not get the option to use a USB stick, so loaded the file onto a DVD-R disk.
When I load the disc the iMac tries to read it then stops and asks to me to put the disk in.
I am logged in to the machine as the administrator.
As a registered MSDN member I downloaded the iso file direct from the Microsoft MSDN website only a couple of weeks ago.
Any asisstance will be most appreciated, as I am a Mac newby and I really want to dump my old windows laptop and desktop machines1

Hi I'd recommend re-posting in the Boot Camp forum, that is where the Boot Camp & Windows guru's hang out.
Good luck.
