Hard drive not recognized when connected to Apple keyboard

Hi there,
I'm using a dock (Henge) for my MacBook Pro with a wired Apple keyboard to which I connect a Passport hard drive using the USB port (my Time Machine backup). The hard drive is self powered but still it won't be recognized by the Macbook Pro. I have used the USB port to connect my iPhone without any issue.
Any ideas? Should I use a USB power booster?
Thanks
CB

The USB ports in the Apple keyboard are NOT powered, so your passport HD will not work on it because it pulls too much power from the USB port.

External Hard Drive Not recognized when trying to boot from it.

So I am trying to boot from my external hard drive through firewire but my computer doesn't seem to recognize the external. There is some problem with my Macbook not booting up correctly and I want to backup my data before reinstalling Tiger. They did this at the Apple store and ran disk utility on it my Macbooks hard drive. I could access all my data, but now when I get home and plug in my hard drive, hold down option after booting, the only drive that pops up is the Mac HD. I read somewhere to try partitioning the external drive as Mac Journaled and I did so with my working Macbook Pro. Any ideas whats going on?

Well i got most of my information off the old one, now I am trying to reinstall Tiger to the MacBook. Problem is I initially tried to do an archive install and the install kept failing after the second disc when it asked for the second install disc.
The people at the Apple store suggested that I try to do a wipe of the hard drive and install. Now when I put in the Disc 1 install disc and boot from the cd drive it just sits for a while and then ejects disc 1 and goes back to the place where the install failed from before ie: it keeps asking for the second install disc.
I can't figure out a way to get around this and just do a clean install on the machine. Any thoughts would be great.

Hard Drive not recognized when booting from XP CD on docking station

The hard drive on my X60 failed to the point where I couldn't recover and reinstall the image. I have backups of all my data and a docking station so I didn't sweat it. Bought a new drive and installed it and this is when the trouble began.
I created an XP CD with SP2 slipstreamed in to make sure I have the latest drivers. I boot from XP CD and everything works until I try to install Windows. According to the installation CD there is no drive installed!
I reinstalled the drive to make sure and this time I booted off of Ubuntu Linux which installed flawlessly. That leads me to believe that there is a driver problem with Windows.
I need help! I would like to install Windows on the machine but nothing I've tried works.

Standard Microsoft XP SP2 does not come with any SATA device drivers.
You have two options:
Go into the T60 BIOS and switch the SATA controller mode away from AHCI to "IDE" mode (or pehaps its "legacy" or "compatibility" mode - I forget what specific term is used in a ThinkPad BIOS).
Find the SATA device driver for XP (it's probably in the Intel Chipset driver download) on the Lenovo X60 support web site, download it and install it using the additional driver installation option which is offered right at the start of an XP install.
If you chose option 1, remember to switch the SATA controller back to AHCI mode in the BIOS after you have installed the SATA device driver.
Cheers,
Bill

Hard drive not recognized during windows server 2008 setup

hard drive not recognized during windows server 2008 setup

Hi,
Whether the hard disk is recognized in BIOS?
Connect it to another computer to see if it could be recognzied incase the cause is the disk itself. Also please check if it is really a RAID instead of a single hard disk - a single disk should be recognized directly while RAID cannot be recognized until
a suitable driver is installed.

[SOLVED]Hard Disk not recognized when installing

Hey all, I'm just starting with Arch and I've had some trouble installing it on my Acer netbook.
My first installation went well except that I had forgot to download the wireless tools so I decided to do a fresh install as I had no access to a wired connection at the time. The second installation attempt must have had some error on my part as Arch failed to start after selecting it from Grub, saying that the kernel was not available/not recognized.
Now my subsequent attempts at installing have failed because the hard disk is not recognized when running either cgdisk or cfdisk. Instead of showing my hard drive partitions after running
cfdisk /dev/sda
it shows my usb drive. If I instead use
cgdisk /dev/sda
it displays an error saying that the disk is damaged or not recognized. When I first saw this I thought my disk was failing, so I tried #! to see if it would show the same error, but it was able to recognize the entire disk and install correctly. Now, even after having the entire disk formatted as ext4 with #! installed, cgdisk is still giving me the same error about a damaged disk.
Am I doing something incorrectly or is there a fix for this? I haven't been able to find any information about this after a good while of searching.
Thanks for your help.

If you mean by trashing the USB flash drive, that it will delete all data and partitions on the selected drive it is correct, because:
dd if=/dev/zero of=/dev/$disk bs=4096 count=1
- this will delete all partition-table data
sgdisk -o /dev/$disk
- this will clear out all data. This includes GPT header data, all partition definitions, and the protective MBR.
/dev/$disk
- this will make you enter ncurses-based GUID partition table (GPT) manipulator, where you can create new partitions
You should only do this if you are certain of what disk it is.
Now if when you said this, you were meaning it will became broken, then it may be a special kind of usb drive because i've donne it many times and i've not broken any.
srs5694 wrote:My guess is that either your hard disk has become /dev/sdb (this can happen in some cases; disk identifiers aren't really fixed) or you're missing a driver for your hard disk controller because you've booted a different kernel or a different initrd file. Another possibility is that there's a hardware fault -- probably a loose cable -- that's preventing the kernel from seeing the disk.
If the usb drive is not where you installed arch, then you need to find if there are more recognized drives:
lsblk | grep disk
And see the uuid of the root partition you want, and add it to your bootloader boot line:
blkid /dev/sdxx

Advanced Format Hard Drive not recognized by HP DV6000 Controller

Hello,
I have an HP DV 6000 laptop (6276 I think, I'm at work can't check) that came preinstalled with a Western Digital 160gb 1.5gb/s 5400 RPM drive (Vista) that failed a couple of weeks ago. So i bought a Western Digital 750 GB WD Black SATA III 7200 RPM 16 MB drive to replace it. I read about people having some problems with Advanced Drive Format hard drives not being recognized by their controller, but also read that depending on the controller and specific Dv6000 model laptop they had-one wouldn't run into problems.
Well sure enough, when attempting to install Windows 7 I received the error that the hard drive was not detected. After researching online I came across an article on WD's site that noted
"Our SATA II hard drives use autospeed negotiation. This enables our SATA II drives to automatically detect the motherboard data transfer rate, making it backward compatible with SATA I data transfer rates. However, some older SATA I controllers are unable to support autospeed negotiation and cannot recognize the drive. This “drive not detected” condition occurs when a chipset is incapable of correctly negotiating the data transfer speed with a SATA II hard drive."
my drive is a SATA ||| but I'm pretty sure it's the same problem. The site goes on to say a fix would be to "purchase and install a third party PCI or PCI-Express Second Generation Serial ATA controller card for your Serial ATA hard drive(s)."
My question(s) are.
1)Is the problem that I am trying to install a Sata ||| hard drive on a laptop with a controller that will only recognize SATA | hard drive?
2) Or is the problem that the hard drive is an Advanced Drive Formatted hard drive and I need to buy a hard drive with out that specification?
3) Or Should I buy a SATA controller card as WD suggests on their website and if so will this definitely allow my laptop's controller to recognize the new hard drive and proceed with the installation?
4)Or Should I just return the hard drive and buy a SATA | non Advanced Drive Format hard drive? (question 2 basically)
Thanks for your help!

Hi @jasmine00
Welcome to the HP Support Forums.
I certainly understand your issue with the drive upgrade. Unfortunately it is a bit of the nature of notebooks, the sacrifice of a large amount of upgradeability, in exchange for compactness and portability. Whenever a new technology comes out, older notebooks are never really going to be easy to upgrade, it at all. Normally the unit as a whole is tested with a set list of hardware, and only those items are supported.
That being said there is this document that could be helpful with your problem.

External hard drive not recognized... help please.

okay, well here is the story:
my iBook G4 had its stock 30gb hard drive in it and it was running extremely low on space. so i figured i didn't want to carry around an external hard drive, therefore i would buy an internal hard drive an install it. so i purchased a new 2.5" 80gb hard drive and called up the local apple store. they told me that although it was under warranty, that it did not cover hard drive installation. so i looked it up online and found step by step instructions to install the hard drive. so after lots of hard work and many screws, i installed the new hard drive successfully... but i still had this perfect 30gb hard drive. i thought maybe to save a few bucks i could turn it into a usb external hard drive. i found an enclosure for the hard drive and a usb 2.0 cable and plugged it into my ibook. it was recognized and everything. i put some files on the external hard drive and transferred it to another mac. this is where the trouble started. i plugged the hard drive into a PowerMac G4, and it was not recognized... so i tried it on a different mac. this time on a PowerBook G4, but no luck. this issue has been troubling me for a few weeks. but then i tried it on a similar iBook G4... and it was recognized. but i don't know why it was only recognized only on the iBook G4 (not the same iBook G4 it was pulled out of) and no other macs.
does anybody have any ideas what we can do to get this hard drive to be recognized by other macs?
any of even the smallest ideas would be greatly appreciated.
thanks,
tyler
iBook G4 Mac OS X (10.4.3)

I can walk you through formatting the hard drive:
1. Hook it up to an iBook that recognizes it.
2. Go into your Applications folder, then scroll down to Utilities. Open Utilities and scroll down a bit and you should see Disk Utility. Double-click.
3. On the left side you should see your internal hard drive and your external one. Each hard drive will have a sub-catagory with the partition indented.
4. Your external hard drive will probably be the second catagory. Click it.
5. In the center-top you should see the tabs First Aid, Erase, Partition, RAID, and Restore. Click the Erase tab.
6. You should see Volume Format: and then a drop down menu, and Name: and a text box. Type in the name you want the external hard drive to be named.
7. In the drop down menu, select Mac OS Extended (Journaled).
8. Then, simply click Erase, watch the progress and it should be good to go!!
Hope I helped you out. Oh, and it might be the enclosure...and also what OS's? Since it's USB it is probably using a USB Mass Storage driver. Mac-wise, if formatting doesn't help, I would get a FireWire enclosure because FireWire is much faster than just USB 2.0. Oh, thats nother thing...Is the enclosure Hi-Speed USB? If it isn't, I would definitely get a FireWire one...If it is, the PowerMac G4 doesn't have Hi-Speed so you're not taking full advantage..Just some insight

External hard drive not recognized in imovie 09 - ! - in a yellow triangle

i'm new to imovie and want to save space on my hard drive by saving files in an external drive
- i'm only able to import to the computer hard drive... not to the external hard drive.
- i can archive video files from the cam to the my external hard drive (500gig passport)
- when i go to import to the the same external drive... the drive is not available in the +"save to"+ drop down menu...only the computer hard drive.
- the external drive shows up in the +"event library"+ window, however it has an +"exclamation point ! in a yellow triangle"+
help!

The external drive must be formatted as Mac OS Extended (journaled). If you drive is currently formatted as FAT32, you can re-format it using Disk Utility in your Applications/Utilities folder.
If you have any current data on the external drive, be sure to back it up before formatting. A format will erase all data that is currently there.
To reformat the drive, open Disk Utility and select the drive. First Partition the drive using GUID (if you have an intel mac, or using Apple Partition Map (if you have some old Power PC macs that will need to access this drive). A single partition is OK.
Then reformat this partition as MacOS Extended (journaled).

MBP Late-2011 hard drive not recognized

Okay, so last November 2012, not even a year after I bought my MBP, it just froze and wouldn't respond to anything. All it showed was the rainbow loading circle and the computer crashed. I brought it to the Apple store and the person behind the Genius bar said that it was a hard drive problem and he replaced it. However, ever since then, I noticed that my mac has been running very slow and programs would take a lot longer to load.
5 months later, my computer is having problems again and one time when I turned it on, it just showed a blinking folder with a question mark. I know this means it can't find the system software. I brought it to a friend and he tried to fix it first by using the OS X system software disc but that didn't work. Then he thought the problem was the hard drive cable so I bought a new one and when he replaced it, my hard drive still isn't recognized. At this point he thinks it's something with the logic board or something since nothing seems to be working. Right now, all I'm doing is connecting my hard drive to the USB and using booting from there. Everything else is working fine. Does anyone have any suggestions as to what I can do? (btw, I don't have AppleCare)
Thanks.

The good news is that it is not the logic board, other wise the MBP would not function at all. The symptoms that you describe are a strong indication that the internal HDD connection is faulty.
As mentioned before, have the technicians at the genius bar look at it and if I am correct, they should be able to install a new cable and allow you to use the MBP with the HDD inside the MBP. This is not an expensive repair.
It is also possible that the replacement cable that was installed earlier was not done correctly.
Ciao.

Replacement hard drive not recognized in mac mini

Hi folks,
I have an issue similar to several threads that were active during 2007 and 2008, but the information and answers given then do not solve my problem.
The original 80 GB Hitachi drive in a 1.5 Mhz PPC failed. I replaced it with a Western Digital PATA 320 GB ide drive and reassembled the Mac Mini.
The original Apple OS X was put in the optical drive and the computer was started with the "c" button pressed when powered on, but repeatedly the disk was ejected after a short time. Since the mac mini does not boot from the proper install cd, I cannot use disk utilities to partition and format the WD drive per the other thread messages.
The WD drive is not formatted for Apple yet. I connected the headless mac mini to an older ibook with a firewire cord and I attempted to boot the mac mini in target disk mode. The ibook never mounted the mac mini as an external drive, an icon did not appear on the desktop, and running disk utilities on the ibook did not recognize the mac mini connected by firewire as a mounted drive. I mounted an Acom hard drive connected by fire wire as a test of the ports and wires and that device was recognized in disk utilities and an icon for it was seen on the desktop.
Back to the issue at hand. What else can I do to partition and format a new hard drive installed in an older mac mini where 1) the install disk is kicked out of the optical drive and 2) the unformatted drive cannot be accessed via target disk mode from an ibook?
Is 320 GB incompatible with a PPC mac Mini?
Thanks in advance for offers of help and correct answers.
Mich

Hi Mich,
the older PPC computers are usualy limited to 128Gb max. HD size.
You need something like this:
"MacOS X 10.4.x and Earlier Hi-Cap Installer.app"
Its available for $25 here:

Memory modules and hard drive not recognized

I removed and reinserted the factory installed Satellite L505D-LS5007 laptop hard drive and memory modules just as practice for installing a hard drive upgrade and an 8GB memory upgrade. The problem is obviously with the memory and not with the hard drive.
After the first practice try, one memory module was recognized. Also for a few seconds after the first practice try, I ran the PC with the battery installed, but no memory installed. I did not look in the User's Guide first to see that I should have removed the battery before removing the memory.
Now the System Indicator Lights for the HDD Activity and Memory Card Reader do not light up. The PC turns on and the display is solid black with no messages.
Before buying new memory modules, what possible ways might there be to get the PC to recognize the factory installed memory modules and hard drive again?
Solved!
Go to Solution.

When troubleshooting, I always change one variable at a time. I would hate to miss a solution by being in a hurry. In this case, you may have damaged either the RAM or the RAM slot. I would stick with the Toshiba specifications for the RAM, making sure it is the correct size, speed and type recommended. I also recommend that when you replace the RAM that both modules be from the same manufacturer, size, and specification. Try one RAM module in one slot and then the other. And then try both RAM modules in both slots. After the testing you should be able to figure if this is a RAM problem or a RAM slot problem.
In the case of hard drives, the real test is whether or not the Bios sees the hard drive. If the Bios doesn't see the hard drive, it's not going to work. The Bios should see the hard drive whether or not the hard drive is partitioned, formatted or has data on it. My experience has been that many Toshiba laptops will work fine with larger capacity hard drives provided they are the same speed in RPMs, have the same interfacing connection and physically the same size.
Again, prior to doing any work on your computer, make sure that both the AC power has been disconnected and the battery has been removed. Be careful out there. A blown repair job by a non-Toshiba tech is NOT covered under warranty.

Thunderbolt partitioned and formatted hard drive not recognized on USB2/3

I have a MBA (mid 2012) and recently purchased a Seagate Desktop Thunderbolt Adapter (STAE129), a Seagate Backup Plus 4TB USB 3.0 external drive (STCA4000100), and Apple Thunderbolt cable. The 4TB hard drive can be separated from the USB 3.0 adapter and the drive placed on the Thunderbolt adapter. I created two partitions (3TB and 1 TB) on the 4TB drive while it was mounted on the Thunderbolt adapter and formatted them Mac OS Extended (Journaled) using partition map scheme GPT. Everything works as expected, the drive hits r/w speeds in the 180 MB/s range (using Blackmagic Disk Speed Test), and no issues at all transferring data to the 3TB partition and using the 1TB partition for TimeMachine.
However, if I disconnect the hard drive from the Thunderbolt adapter and place it on the USB 3.0 adapter and connect it to my MBA, Mountain Lion says "The disk you inserted was not readable by this computer and gives me the options to Initialize, Ignore, or Eject. Going into Disk Utility app, the drive shows up without the partitions I created when the same drive was mounted to the Thunderbolt adapter (just shows disk1s1). In fact, the drive label (Disk Description) is different too and the Partition Map Scheme now shows MBR!
To try work-arounds, I went ahead and repeated the partitioning and formatting steps with the drive attached via USB 3.0 and all works fine until I put the drive back on the Thunderbolt adapter where once again OSX reports that the disk is not readable. I've even tried a single partition with no luck. In short, the drive partitioned and formatted on Thunderbolt is unrecognized under USB and vice versa.
Shouldn't the disk preparation and data be consistent across these different interfaces? I would think so. My biggest concern is that if I had a failure in the Thunderbolt setup (assuming the drive itself does not fail), then I can't access my data. This is not a very comfortable situation.
I'm assuming I've overlooked a very basic detail. Appreciate any steer to solve this problem.
Thanks,
Rob

Thanks for that, I recently ran into the same problem. I even chatted with Seagate tech support and they didn't know the answer.
My situation is a bit different from you. I bought the 3 TB Thunderbolt version of the drive directly and then purchased a USB 3 adaptor seperately. You see, I still own a 3 year old Macbook Pro that doesn't come with a Thunderbolt port. I was looking to upgade to a MacBook Air later. I thought that I might as well buy the TB version now.
In anycase, my old MacBook Pro won't see the drive when I use the USB3 adaptor. I get the same exact error message as you did. I can't really test it on Thunderbolt since I don't have one. I'm going to go install the Thunderbolt drivers now and hopefully, it will recognize the drive afterwards. I'll let you know what happens.
BTW, I was thinking of reformatting the drive with NTFS so that I can use the drive on PCs. My mac has the NTFS drivers loaded so it's no problem. I hope this won't screw up the Thunderbolt connection later when I do get the Macbook Air?

New WD Scorpio Black 750GB hard drive not recognized

Hey guys,
I've purchased a WD Scorpio Black 750GB hard drive for my newly acquired MacBook Pro 5.5, 2.26 GHz Intel Core 2 Duo. The hard drive is installed (internal) but not being recognized by disk utility. Browsing on Google, I've found this to be a common occurring problem but as there were no direct solutions, I'm posting this in case anyone has any solutions to this issue.
I've reset the PRAM/ NVRAM with no avail. Any assistance would be greatly appreciated.
Cheers

Your response is not 100% clear to me.
Have you actually installed the WD and Seagate HDDs in the MBP or just connected them while in an external enclosure?
When you put the original HHD back in the MBP, it is recognized in Disk Utility but cannot be repaired? Is that the case.
Have you tried to put in the original Installation disk and has the original HHD been recognized and/or one of the other HDDs in an enclosure been recognized?
Ciao.
