Hard drive not recognized after a brand new replacement put in 2 weeks ago!

Basically, my MBP was having the symptoms of needed a new hard drive. It was taking abnormal amounts to think and load thinks when it started up (only part of the time). I cleared all the software off of it and reloaded Mac OS just to be sure it wasnt a software issue. Apple took my computer and replaced the hard drive about 2 weeks ago (90gb, 7200 rpm). By the way the MBP is a C2D with 2 gb ram.
Immediately after getting my computer back it seemed to work fine. It has been about a week and a half since I got it back and last night trouble started. First, it wouldnt boot up all the time (id get the flashing question mark on the folder). I checked startup disk and booted it that way, no results. When it did start up, it would lock up shortly after when using applications such as safari. I then booted it to the system disk and performed the first aid functions on the disk... no results. And now, the next morning, when i boot to the disk, the hard drive itself is not even recognized under disk utility??? So basically, I cant reload OS again because I cant see the installation disk. Is this a a hardware issue even though I just replaced the hard drive?
what do i do??

Hi MBPrunner;
It appears you have the misfortune of infant mortality whereby a bring new part fails in a short period of time. This does happen. I have seen it numerous time in my years of server support at IBM. My suggestion is take it back it back to Apple with all of your paperwork. They should make good on it.

Hard drive not recognized after lion upgrade

My hard drive WD "My Book Studio Edition 1TB" mounts and unmounts non stop. Firewire or UBS is the same. Also with a new firmware of the disk and after a formatting. The file system is HFS+ journaled. My hardware is an iMac early 2009 24". No problems with all the other OS.
What's happen with Lion, Apple?

Hey Yelghoul,
Make sure that the drive does not have the WD encryption stuff on it. That causes the Mac to render the drive unreadable and useless. Use another computer to remove the software and any passwords on it. Then plug the drive back in. If there are no files on it, simply open "Disk Utility" under "Utilities" to reformat the drive to make it usable with Lion or other computers.
Best of luck,

WD external hard drive not recognized after improper eject

I have a WD Passport external hard drive that I've been using for a while with my MacBook Pro. The cord got yanked, causing the drive to improperly eject. Now my computer isn't recognizing the HD. Help! Of course EVERYTHING important is on this drive!
I tried plugging it into a Mac desktop, which also did not recognize the drive.
I plugged a different Passport into my MacBook Pro, and it was recognized, so I know it's not the USB Port that's causing the problem.
I used the cord from the HD that mounted with the problem HD. Didn't mount with the new cord. So I know it's the passport that's causing the problem, not the MacBook, not the USB port, not the cord.
I ran the disk utility, and the HD does not appear...It is powering up though- the light on the HD is lighting up. Oh please help!
Did I kill my disk? Of course I just moved my entire iPhoto library to this location, and I haven't backed it up yet....

No. It may just require a 00 Phillips driver depending upon the enclosure. Do the swap on a towel so that the little screws don't bounce away from you. You will have to pull the HDD out from the connecting plug. Do it in a straight line,don't bend it, and you may have to slowly increase pressure to get it out of the connecting plug.
It's not rocket science.

Hard drive not recognized AFTER installing leopard

So I installed Leopard on my 12in Powerbook G4, having the usual problem of non-recognition of my hard drive (from a third party) but was able to install Leopard after fiddling with disk utility.
Now the computer will not recognize the hard drive after I restarted it. I've tried rebooting holding down the option key and selecting the hard drive and it still didn't recognize after restarting (it shows a prohibit sign). Also tried booting in single-user mode but it keeps waiting for the root device forever.
Has anybody had a similar problem?

Unplugging worked!!!
I have no idea what PRAM is but someone said that unplugging your computer resets it so, I thought I'd give unplugging a shot. So, I shut down my computer and unplugged it. I also unplugged the power on the HD. (because I wasn't sure which one they were talking about.)
Anyway, I went away for about five minutes.
I came back plugged in the HD power first. Then, I plugged in the power cord for the computer and turned it on.
As soon as I logged in I was asked if I wanted to use my external HD for Time Machine backups.
I saw the icon for the HD on the Desktop where is belongs. I can open the drive and access the files with no problem.
Try this if you haven't yet.

External hard drive not recognized after power outage

After a power outage last night my WD external hard drive is not showing up. The power light is on on the drive, the DVR is working normally, except my external drive is not showing up. I unplugged power from the DVR and restarted it, but no change.

I have a 2G Samsung drive in Rosewell external encloser running for over a year. Two times have lost power and DVR would not recongize external drive. The procedure I used was to reboot twice via menu>settings>customer support>in home agent>reboot STB. Mine required two resets, the first reboot looks like DVR recongizes drive but does show as available but second reboot shows disc activity during last part boot up of box then external would show with all recordings and normal operation. I have not lost any recordings.

Now, USB External Hard Drive Not Recognized after 10.6.8 Update

My external Hard Drive is not recognized on start up. I have to unplug it and plug it back in for it to be recognized.
All this since 10.6.8 updated today.
I'm a fool for updating the same day.
This has happened before and I always forget the bugs in the software when it first comes out.

Alright, I'm gonna go ahead and close this thread. I found out the solution to my issue. Turns out it was a problem with a system file I changed right before installing. The error only occurred on a restart... the required 10.6.1 reboot was the first reboot since the change, so thus it looked like the culprit.
If you want a more thorough explanation of my problem (highly HIGHLY doubt it's gonna help you guys out), check this thread --> http://forums.appleinsider.com/showpost.php?p=1480362&postcount=8
Sorry for the trouble!

Lacie External Hard Drive Not Recognized After It Previously Was

I have a 1 Tb Lacie Big Disk External Hard Drive that I have used for a couple years now. I have a Mac Pro, an iMac and a G5 computer that I have previously used with it. After I transferred it between computers yesterday suddenly it will not show up on any of the computers. I have tried different cables and inputs, computers, other hard drives with the same cables (they worked), restarting the computers, etc. The hard drives powers on like normal and you can hear it running, the blue light comes on in the front, but it never gets the disk loaded on the computer. There is a "auto/on/off" button on the back that I have tried switching between but nothing seems to work. Please let me know if this is a common problem and any way to get it to work as I would prefer not to lose the information on the hard drive, especially when it seems to be functioning just fine aside from not appearing on the computer.

Even backups need backups too.
And a 'good' case is one where you can pulll the drive out and pop it into your Mac pro drive bay.
power supply bricks are known issue.
Mac OS updates that affect those models.
LaCie almost by their own invented the term and idea "reset firewire bus" routine after all.
Years and you can assume not forever but eventually it could and will fail.
I'd pick up a "spare" or replacement unit, one with eSATA/FW800/USB3

CallDigit 2 x SATA plus 2 x USB3 $139 - USB3 card and interface works better even on legacy (how long and old is USB2 now?) USB drives.

External Hard driver not recognized after force eject while Mac was asleep

So my Samsung hard driver had force ejected itself when my Macbook pro was asleep, it cant be recognized anymore. It doesn't show up under utilities, however it does show up under System report.
I've tried to plug it onto my desktop, however the system had failed to install the software to run the hard drive, yet again it does show up under properties.
Help please???!!!

No. It may just require a 00 Phillips driver depending upon the enclosure. Do the swap on a towel so that the little screws don't bounce away from you.

External hard drive not recognized after time machine locked up

I was backing up to an external hard drive (300GB Western Digital) and time machine locked up. I had to shut down the computer and restart. Now the external hard drive does not show up on the desktop?
I can see it in disk utility but I am not able to mount or unmount the disk, I keep getting an error that the disk is in use. I tried to erase/reformat the disk and no luck.
Any suggestions?
Thanks for the help

Do I need to boot from the install DVD?
this is often the easiest and eliminates any "busy drive" problems. what's wrong with booting from the install DVD? takes a couple of minutes.
My main hard drive is OK... the drive that I am having problems with is an external hard drive that I was using to back up my lap top. I just want to get the external drive reformatted, but disk utility will not erase it. I get an error that disk utility shut down, "please check the drive and make sure that the drive is not in use or programs are still running"
Is their a way to do a hard or forced reformatting of an external hard drive, I don't care about the information on the drive
I also tried disk warrior to recover the info on the disk and all it does is crash my mac pro????
Thanks again for the help

Micronet 500 GB Hard Drive NOT recognized after 1 year of seamless use

Micronet 500 GB Hard Drive
Firewire 400 and 800.
I always use the 800. I plugged it in today and the hard drive start-up fine as usual. Without even looking on the desktop I opened Final Cut and it told me it could not locate my scratch disk (I always use the 500gb for FCP). I've tried different cable, and using the Firewire 400 instead of the 800. I don't know what to do, I had wanted to put some things on video for christmas and I don't have space on my startup disk to put video (hence the need for the external). Please someone help me, I don't know what to do. I'm terrified of the thought that my external could be dead or something like that. Please help! Thanks, Mike!

Most persons that have installed an SSD that was smaller than the factory drive have been unable to use any HP Recovery Media with the SSD.
As an alternative, if you can still read the 25-digit Windows product key on the Microsoft COA affixed to the bottom the computer, you can install Windows 7 Home using this key. Please see "How to Install Windows 7 Without the Disc" for instructions on how to download Windows 7, create the installation media, and install Windows 7 using the 25 digit product key from the Microsoft COA on your computer. Please note that this installation will not have any of the HP customizations or HP value-added that was original installed on your computer. Also note that you will need to download and install most of the drivers from the HP G62t-350 CTO Notebook PC Drivers page.

External hard drive not recognized after OSX Mavericks

My Toshiba external hard drive worked flawlessly before I upgraded to Mavericks, but now I cant access the disk. It doesnt show up on the desktop but it does show in disk utility. What do I do?!

This isn't my question, but I'm having the same problem (with a Western Digital) and thought I'd share a screenshot of disk utility for comparative purposes.
Also, Mavericks isn't allowing me to access Bootcamp

Usb hard drive not loading after security update

usb hard drive not loading after security update
I can't seem to find any other posts about this problem.
I have three external hard rives connect by a USB hub to my iMac.
Problem is that if I turn on the hard drive(s) AFTER start up I get a message that the drive either was not recognized by the OS or that it was ejected unexpectedly.
I get the same issue but not all the time if I turn them on before I boot the iMac.
I used the disk drive utility to "repair" the drives but they always come back as "probably ok".
If I restart the iMac with the drives connected (on), it seems to work but not all the time.
A bit annoying as I am wondering if the drives are OK or not.
I don't always need the drives as they are for backing up images from my camera using Apreture.
This all began after i did the latest security update.
is the update to blame?
mahalo.

Yes, you can still use those instructions to reset the PRAM.
You said that you booted to your install disk and that your primary drive did not show up at the Select a Destination screen? That usually means that the computer is either not recognizing your partition, or it's not recognizing the hard drive itself.
Start with this article and follow all the steps even if you already tried them. I suspect that you'll get to step 4 and you'll end up having to call Applecare. If you haven't done those steps, they're most likely going to make you do them anyway, so you might as well get them done before the call.

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.

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.

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.
