My MacBook pro won't recognize hard drive I put in it. It boots only to a white screen unless I boot to my recovery USB. If I do that then I can select my USB and my external time machine drive in the disk utility, so no problems there. But what do you

My MacBook pro won't recognize hard drive I put in it. It boots only to a white screen unless I boot to my recovery USB. If I do that then I can select my USB and my external time machine drive in the disk utility, so no problems there. But what do you think it is? It won't recognize any hard drive I put in the machine, so might it be the sata cable?

Boot the Recvoery USB, use Disk Utility to select the internal drive makers namea and size on the left.
Now select erase and select the midde option and click erase, it will take a bit to complete but it's best for the drive.
Now select Partiton tab, click the big box and Options: GUID and then Format: OS X Extended journaled and click apply.
Quit and you should be able to install OS X now with your Apple ID and password.

Computer Won't Recognize Hard Drive

I wanted to do a clean install of OS 10.5. Wiped hard drive using Tech Tool Pro 4. Now computer won't recognize hard drive during install. When it asks to what volume I want to install the OS, the screen is blank. This is a new one on me.
Anyone have any ideas? Thank you.

Boot to the Installer/Utilities DVD, but DO NOT Install.
Answer only the "what language" question if presented, and wait a quarter minute for the MenuBar to be drawn. Choose Disk Utility from the Utilities menu or the Installer menu.
Use Disk Utility to Erase the drive again. Be sure you are getting Options GUID partition map.
Then use Disk Utility to partition the drive to one partition, Mac OS X Extended (Journaled).
Select the drive and choose Mount. It should not produce an error. Now you are good to go on the Install.

Try repairing it:
Open Disk Utility in the Utilities folder. Select your Time Machine drive in the list on the left. Click on the First Aid tab in DU's main window, click on the Repair Disk button.

Macbook pro flashing question mark folder, won't recognize hard drive

My 2010 macbook pro froze and after restarting I was greeted with a flashing question mark folder. I then restarted again and held down "option" key and went into Mac OS X utilities then into disk utilities. In disk utilities, my only drive options are "superdrive" "disk0" and a subfolder of "disk0" labeled "Mac OS x Base system". My hard drive is no where to be seen. I also tried to install a new hard drive but the same thing happened, the computer could not recognize that there was a hard drive present. What can I do to fix this??

Hi bigdubee,
The exact same thing happened to my 2010 MacBook Pro today. Restarting with the "option" key held down, I get only 2 of the 3 options you listed in disk utilities ("disk0" and a subfolder of "disk0" labeled "Mac OS x Base system".
Did you take your Macbook Pro to the Apple store? And were they able to fix it?

Install Disc Won't Recognize Hard Drive

Perhaps I should take it as a sign from above and NOT install.
When I went through the install, my internal hard drive wasn't recognized but my two external hard drives were. I restarted after turning them off and this time no drive was recognized -- there was the ? mark and the CD rom as my two options when I attempted to quit.
I chose network since I had no choice and luckily the system booted from my hard drive and is working normally.
I hesitate to try again -- haven't seen posts with this problem.
Anyone have any insight?

First, be sure your internal drive is formatted/partitioned GUID with the Mac OS Extended (Journaled) filesystem.
Perform a disk check/repair and a file permission verify/repair.
Zap the PRAM and NVRAM
That is about as clean as you can make your system.
Let us know if it works this time.
Maybe it was a message from on high? Letting you know you were not yet ready?

Mavericks won't recognize my lacie external hard drive

I've been using a LaCie external hard drive for my Time Machine backups and it's been working fine until a couple of weeks ago. Mavericks no longer recognizes the drive. I tested the drive out on a non-Mavericks Macbook and it booted up fine. I see there are issues with this, but wondering if anyone has a work around or if you've found there is a fix I can do? Really frustrating to not be able to access my archives or be able to back up my work!

Apple doesn’t routinely monitor the discussions. These are mostly user to user discussions.
Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

Have you tried basics from the manual?

IMac with Mavericks won't recognize new 60D

iMac with Mavericks won't recognize new 60D

No drivers are required on the Mac to use the camera. The Mac will natively recongize the camera.
You can install Canon's supplemental software or you can use the Apple provided software or 3rd party software.
However... when you connect a camera to a Mac and it recognizes the camera, you *can* configure what you want the computer to launch. By default, a Mac will usually launch iPhoto.
If you open iPhoto (do this EVEN if you don't want to use iPhoto) then go into iPhoto -> Preferences and look at the "General" category. You'll see an option that reads: "Connecting camera opens:" with a selection menu next to it. You can use that menu to pick what you want your Mac to do, then close and quite iPhoto.
When connecting the camera to the computer, do the following:
Turn the camera off
Use the supplied USB cord to attach the camera to the computer (some caveats here... I'll mention them below).
Power the camera on after it's attached.
About those caveats on step 2.
The reason I say "use the supplied USB cord" instead of use any USB cord is because if you're like me... you've got LOTS of USB cords laying around. Some of these come with devices that use USB for charging purposes. And some of those USB cables ONLY bother to wire the power supply pins and not the data transfer pins. In other words... it looks like a normal cable, but wont actually allow for data transfer. You will need to take care to make sure you're using a proper cable.
Next I should caveat the use of USB hubs. Whenever you're having a problem with a computer not recognizing a USB device, it's a good idea to disconnect extraneous USB devices that have nothing to do with your issue AND if there's a USB "hub" involved... bypass the hub and connect the camera directly to a USB port on the computer itself.
I use a USB hub and this particular hub is reliable... but truthfully I had to buy three different hubs before I found one that worked reliably. I've discovered there are a lot of flakey hubs on the market. When in doubt... bypass the hub. If you find that you can get your computer to recognize your camera on a consistent basis if you bypass the hub then you can direct your attention to finding a reliable hub.
That's the end of the caveats.
I wrote a response to a user with a similar issue in which I detail the steps to use the Mac's System Information utility to determine if the camera is showing up as connected to the camera. You can find that post here:

P965 won't recognize optical drives and can't undate BIOS thru LiveUpdate

Changed mobo's from amd x2 to P965 Platinum and all went well except that mobo won't recognize optical drives either through USB or IDE channels. Heard I needed to upgrade the bios but every time I use Live Update it gives me a "Copy file fail" error. The floppy drive works fine for other tasks and copies fine. Changes floppies and no luck and same result. Tried at least 10 times.
Any help appreciated. Thanks
tg

Before I waste any more time let me try a clean install and see what happens. My old program drive was an IDE drive and I will see what happens when I install on a SATA drive. I'll be back if problems arise. Thanks to all.

TS1369 this is the first time that i'm trying to connect my new ipod shuffle and my computer won't recognize the driver?

My computer won't recognize the driver for my Ipod Shuffle. This is a brand new ipod so why is there an issue?

Have you tried uninstalling and re-installing iTunes and all other Apple software to see if that makes a difference? Use the exact instructions in this article.

I have downloaded mavericks to my external hard drive, what do I do next to go back to using Mavericks?

i have downloaded mavericks to my external hard drive, what do I do next to go back to using Mavericks?

I would not use Time Machine for this task. Rather I suggest you clone to the external drive. You can then boot from the external drive to restore your clone. First, purchase Carbon Copy Cloner.
Clone using Carbon Copy Cloner
1. Open Carbon Copy Cloner.
2. Select the Source volume from the left side dropdown menu.
3. Select the Destination volume from the right side dropdown menu.
4. Click on the Clone button.
5. When completed select Disk Center from the Window menu.
6. Click on the Recovery HD tab then select the backup drive from the list.
7. Click on the button labeled "Create a Recovery partition for this volume."
Destination means the external backup drive. Source means the internal startup drive.
You now have a fully bootable copy of your iMac's hard drive. When you receive your iMac back after the drive replacement you can boot it from this backup and use Carbon Copy Cloner to restore the backup from the external drive to the internal drive. The process is identical except you will switch the Source and Destination volumes - Source will be the external drive; Destination will be the internal drive.
Because the newly installed drive will most likely have OS X installed you can skip Steps 5-7. You can now continue to use your external backup drive by setting up scheduled backups with CCC. No need to use Time Machine.

Since I upgraded to Mavericks, my Maxtor external hard drive doesn't work. What gives ?

Since I upgraded to Mavericks, my Maxtor external
Hard drive does not work. It is FireWire to
Thunderbolt . When I connect it it crashes. What
Gives ?j

Maxtor, must be an old one.
There is a disconnect occurrence in some cases with FIREWIRE ext. HD and Mavericks.
(indications mentioned on the Mavericks board)
This is known and being looked into.
Ive looked into this much myself.
Suggest using another Mac and offloading data onto a USB3 and using same until there is resolution.
Any normal USB ext. HD is working fine.
Peace
