External drive not detected

Hi,
Just transferred from a macbook 2008 to a brand new mac mini 2014.
My backup was on an external drive, but when it's plugged to the mac mini, its not detected, but it is on my macbook ....
what can I do ?

The warranty entitles you to complimentary phone support for the first 90 days of ownership.
If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

External monitor not detected on Thinkpad W530 intel-virtual-output

I'm having problems with connecting my ThinkPad W530 to external monitors since a few months. I'm using NVIDIA Optimus and bumblebee/optirun since the VGA and Mini DisplayPort connectors are only wired to the NVIDIA card om this laptop. For a long time I have executed:
$ optirun true
$ intel-virtual-output
Then I have started the Screens GUI tool in Gnome to setup the placement of the external screen but now the external screen is not present in the GUI tool and xrandr gives me:
Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767
LVDS1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 193mm
1920x1080 60.00*+ 50.00
1400x1050 59.98
1280x1024 60.02
1280x960 60.00
1024x768 60.00
800x600 60.32 56.25
640x480 59.94
VGA1 disconnected (normal left inverted right x axis y axis)
VIRTUAL1 disconnected (normal left inverted right x axis y axis)
If I select "Discrete mode" and select startup screen as VGA in the BIOS the BIOS and the Grub screens shows on the external monitor but the screen locks on the screen that shows that the system is booting with the linux-ck kernel. This has never worked for me in Arch Linux so that is no surprise. In Ubuntu everything everything worked fine the last time I tried.
How can I debug this? Why is the external screen not detected any more?

Thanks, I am not sure exactly how to read the logs but I cannot find anything that is obviously wrong
Below is my log with an external screen connected via Mini DisplayPort and after running:
$ optirun true
$ intel-virtual-output
a few times, no more logs seem to be added when I connect/disconnect the monitor or when I run the above two commands more times.

External drive not showing in Time Machine back ups

ok, I have several problems, the first one being the fact that my external drive, where I have all my data, is not mounting or sometimes it mounts but soon dissapears. I was not worried at the beginning since I thought, that is why I have time machine, I have all my files backed up. However, the external drive does not show in any of my back ups. It dissapears from Time Machine too so all my previous back ups from the external drive dissapeared too. I have all those backups before. Any ideas of what is wrong? I have 10.5.8

Thanks a lot. I am sure I am doing somethign wrong but since the external hard drive can not be seen any more, I don't see it either in any one of my back ups. It does not show anywhere.
Also, my external drive gets detected sometimes, I run Repair Disk, it says it is fine, then it works for a while and then it stops working. I need to turn it off, then turn it back on and again it works for a while. I have run disk utility everyt time when the hard drive works and still says it is ok, then it stops working again after a while. Any ideas with either one of these problem ( or both)?
Try other ports and cables. If it has a separate power supply, try plugging-it in to a different outlet. Make sure all the connections are secure. Can you try it on another computer?
Your disk may be failing, or need a firmware update. Check with the maker's website, support and/or forums.

Is it possible to have Time Machine backUp computer HD AND external HD connected to Airport Extreme.
Sorry, but no.
Time Machine will backup your Mac, but not the hard drive attached to the AirPort Extreme.
Time Machine will back up a hard drive only if it is attached directly to your Mac via USB or FireWire.

Hi Virendrasingh,
Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your HP Notebook and CD/DVD not working correctly. I would perform a hardware test. Where did the CD come from? Were you having issues with the CD ROM before? I would be happy to assist if needed as there are many models of HP Notebook, I would need the model number. How Do I Find My Model Number or Product Number?
Please respond with which Operating System you are running:

USB External drive not showing in Finder, or on Desktop

I have two USB external drives from the same manufacturer. One is for regular storage, the second is for Time Machine and movies.
The first one shows everywhere, on the desktop, in finder and in Disk Utility.
The second drive shows in Disk Utility only. However, it is functioning fine with Time Machine. So it is mounted. I have tried several repairs, and it reports no fault found. So it is certainly functioning correctly, but a setting or error in the operating system is not allowing it to be viewed in finder, or on the desktop.
Any suggestions.

Correction: Title should be Firewire External drive not showing in Finder, or on Desktop.

Is their another way like to use my time capsule as an external drive not using time machine?thanks

is their another way like to use my time capsule as an external drive not using time machine?thanks

You do not have to use Time Machine.. but the TC is hardly suitable for a NAS.. it has no means to back itself up and is relatively slow. Still that is up to you..
CCC or Superduper are good backup softwares .. and there are a number of others.

TM - External Disk Drive Not Detected in Recovery Mode

Hello Apple Lovers,
I am using the My Passport for Mac 500GB disk drive with time machine on my MacBook Air to create data backups.
I checked the disk for any corruption using Disk Utility. No issues were found. I find the disk works excellantly in terms of creating backups and restoring them inside time machine.
I cannot detect my external disk for restoring entire images of the OSx in recovery mode. For some reason, TM will not detect my backup disk in the recovery mode. I use the WD Security software on my disk to lock it, however, never before has the security lock posed any problem to me. I used to see a prompt appear for me to unlock the drive in recovery mode on attempting to access the TM backups.
Please take your time in replying to my post. I recovered my entire system last week and restored all the data using TM's twlight view. No rush! I successfully created a backup of my fresh OSx Mavericks on the MacBook Air with all the data restored using TM. I only wanted to troubleshoot this issue in case something occurs in the future that may require me to restore data using TM in recovery mode.
I browsed extensively through many of the discussions covering Time Machine. None mentioned my particular dilemma. Any assistance would be a valuable controbution not only to me, but other Apple users who may purchase My Passport for Mac drives and encounter a similiar problem.

You will need to avoid using third party software if you hope to access the disk and data in recovery mode.
If the WD software encrypts your data recovery mode will need a way to decrypt it. Recovery mode is a 'reduced mode' that only runs Apple software (not third party software) so the WD drivers that decrypt the disk will not be installed & Disk Utility or Migration Assistant will not be able to open the data on the disk.
There have been long threads that make me steer clear of using ANY Western Digital drive software with 10.9.
https://discussions.apple.com/thread/5475136?start=0&tstart=0
https://discussions.apple.com/docs/DOC-6202 <- WD had to remove software from Macs because it ruined peoples data on 10.9.
There are other threads on WD disk tools causing errors on 10.9, external hard disks do not require the use of additional software on OS X - these apps & drivers are mostly junk that is not a good idea to install.
If you really want to protect your data with encryption the features are already built in to OS X, it's called Filevault. It will encrypt your internal HD & your Time Machine backups (when the OS is encrypted). It works with Apple tools & doesn't rely on any third party drivers.
You will need to disable the 'WD security lock' and make sure the disk works without the WD software if you hope to have any chance of reading it in recovery mode.

External hard drive not detecting

Hello,
I have installed Win 8 to my system which is having a 2.5GHz processor. That's fine.
But When I am connecting, an External SATA I hard drive through enclosure, Its not detecting.
But It is able to detect all other external hard drives.
please let me no what to do.
Thanks in advance,
Giri.

Hi Giri,
What's the size of your External HDD?
Please know that if the disk format is MBR, system can only recognize 2 TB of it. Please understand that the MBR Partitions can define a disk drive capacity up to 2.2TB. If we need to use more capacity of the HDD, we need to convert it to GPT format.
Also, you can try to change to cable power connector to see if this issue can be caused by insufficient power supplication.
Thanks for your understanding.

it worked then couple days later it was gone again.
i have removed the dvd from laptop and clean the connection and put it back still the same.
i was told to remove any burning programs and reinstall so i did that and the drive came back then after reboot went again.
the dvd drive ejects and has power and attempts to read the disk but its just not detected in my computer.
i have even been into the bios and put cd drive as boot first.,
then put my bootable xp pro disk in and it wont boot from the bios.
so i thought i would try an external drive to boot from bios, and it doesnt boot from there either.
i have had the drive randomly pop up in my computer and then after a restart it would be gone again.
so i cant put a fresh install on my laptop and i dont know what else i can do.
any help
thanks

How old is your laptop?
Have you had any other problems, besides the dvd drive, in the past few months?

External HD not detected in MacBook but iBook

Hi All:
I have below systems with me >
* iBook G4 running Tiger with 1GB memory
* Previous MacBook running Tiger with 2GB memory
* New MacBook running Leopard with 4GB memory
* New iMac running Leopard with 4GB memory
I have a 100GB external HD connected to my iBook for 2 years now, via USB. And my Previous MacBook used to read and access data from the same HD too. I dunno if I have changed any setting or any software update technically forbid the access from any other Mac systems except iBook, which I bought with.
In iBook, the external HD works perfectly. I eject it, connect it to any of my MacBook now, the light on the device is turned on but nothing moves in Finder. There's no icon, unlike in iBook where a USB HD icon appears below Macintosh HD. I tried to partition and erase everything, remain Mac OS (Journaled) format, but no luck. It's properly detected and accessible by iBook but not any others.
Have I possible changed anything without knowing it ? Can someone share with me what to do next ? The external HD works well but I dun understand why none of other Mac systems recognise it, except the original iBook. Thank you.

Hi:
I am using a 100GB from Samsung. Should have mentioned earlier. It's USB-powered. I never use it with any adapter. I just plug it into iBook G4 and in less than 2 seconds time, drive pops up in Finder perfectly.
However with MacBook running either Leopard or Tiger, the light will be on and you hear it spinning. I tried to plug in adapter last night, still no luck.
I re-partitioned to GUID or Master Boot or Apple, either Mac Extended (Journaled) or MS-DOS, none of them works.
Then, last night I tried to boot-camp Windows XP and to my surprise, it was detected without any problem ! Oh...... So now I think the problem is not in USB port, not in the power adapter (which I never use), not in the format, it's in Tiger or Leopard for MacBook.
Tiger I use on iBook G4 is 10.4.11 (no problem at all)
Tiger I use on MacBook is also 10.4.11 (not detected but light is on)
Leopard I use on MacBook is 10.5.2 (not detected but light is on)
I spent so much time transfer data from external HD to iBook then to iPod then to MacBook. I just dun understand. Thank you for all your posts. ^_^

External Hdd not detected

Hi guys,
I've got this issue where my Macbook Air cannot detect my external hdd (not showing up on disk utility), where as my Mac Mini can. I assume it's a software issue. Both are running OSX Mavericks (Latest edition) and there is nothing wrong with my USB port in the Air (detects my mouse, flash drive etc.).
The hdds' LED no longer flashes when plugged in the Air but functions fine when plugged in the Mac Mini.
Is there any manual reset command (through Terminal) or setting in the Macbook Air without having to factory reset?
Thanks in advance for your help!

If the hard drive is bus powered (it doesn't have an independent power supply) the MBA may not be supplying enough power to the drive. This isn't an uncommon problem. I have a cheap external at work with this problem which I solved by plugging it into a powered USB hub instead of directly into the computer. Had that not worked I'd have tried finding an external power supply for the drive - or junking the enclosure.
