USB hard drive not detected on reboot

I am running Windows 7 Ulitmate 64-bit on my 2011 15" Macbook Pro. I have a USB Hard Drive (WD My Passport SE - USB 3.0/2.0 - 1 TB).
The hard drive is formatted for HFS+ and I am running Mac Drive 8 to detect it in Windows.
For some reason when I reboot (in Windows), the hard drive won't be there until I unplug it and plug it back in.
This is really annoying! Can anybody help me? I'm pretty good with things like this but I can't think of any reason this shouldn't be working right.

I am having the exact same problem. WD 1TB Passport. USB 3.0 drive. Running on Windows 7 Pro 64 via Bootcamp.
My 1TB Passport is formatted with FAT32 and works with Windows and Mac OS.
I was getting the same problem when I was running Windows XP Pro on the same MacBook Pro. I was hoping the upgrade to Windows 7 would remidy the issue but it did not.
The drive light is on in a steady state when I boot and I have the same symptoms as reported by everyone else above.
In my research, I am leaning towards thinking that it is a power issue related to the cable used to connect the USB 3.0 Drive or something to do with the USB driver for Bootcamp, but researching the WD site suggests it's a power issue, not a faulty or failing drive.
I have a 500GB WD Passport USB 2.0 also attached to my computer, also running FAT32 and it starts up no problem. It's just the USB 3.0 drive that is having this issue.
Also worth noting; the drive is detected properly when I boot in Mac OS X. It's only the Windows side I have to unplug and plug back in to access the drive.

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 Detected load sata drivers

Hi everyone I have a G6-1189sa notebook, I had a faulty harddrive so replaced it with the exact same drive 750GB WD, Thing is I could not save anything from the original drive ? so no recovery partitions are anything I even lost all my family photos and software.
Ok so I done a straight swap over and went ahead installing my fresh Windows 7 x64 disk, then I got an error message saying no device detected please install driver etc etc.
I know I need to install the sata driver for the harddrive to be detected, so I extracted the HP sata control driver to a USB pen the tried to load the driver, with the load driver option on the install disk.
Error message saying driver is not signed !!!! So after some reading on google I learned I had to disable the naitive sata option in the bios settings for the harddrive to be detected.
Thing is there is not a option for this in my bios ? unless Im missing something like an advanced bios setting.
I even went to the Intel site and tried some of there drivers but I get the same error message driver not signed.
So my question is ? how can I disable the native sata option if Its possible , If not how can I load the HP sata driver if its not signed.
Its very anyoing someone even said I have to slip the drivers in and make a new home made W7 disk myself to get my pc working again what the hell, where would I start.
Maybe I should put the laptop in the post and send it back, Ive never had so much trouble before making simple memory and harddrive exchanges.
Any advice please people Im at my wits end, my laptop is only a few month old and its now a door stopper lol

Hi,
Boot into the bios and be sure that the hard drive is detected.
Sata drivers are included in Windows 7.
Return the bios to its default settings and use the HP Recovery Disks. If you don't have the Recovery Disks then order them from HP. Order HP recovery Disks.

External USB Hard Drive not showing up on Time Capsule

Hi all,
I have a 500 Gb Time Capsule that used to be able to detect my external USB hard drives. I had to store my things for a while and have just started using the Time Capsule again. The TC works fine, however, the same USB external hard drives I used to connect to the TC are not showing up anymore :s They show up on the desktop when I connect them directly to my MacBook via USB. I have been through most of the file sharing options in Airport Utility and System Preferences but have not been able to solve this. I can't think of any settings that would have changed from when they were showing up in the past. Any help would be greatly appreciated. Thx

yosemite won't work with ntfs drives for some reason, i've had the same issue with my toshiba. i thought ok lemme buy another one, and transfer it over maybe it's a driver issue which i've tried over and over, apple support can't figure it out.
here's a simple fix, but the problem is i have an external where all my photography and video files are stored, so i can't access them right now and it's making my life ****.
http://guides.macrumors.com/Formatting_an_External_Device
that does work and make the drive mountable now, but problem being i can't obviously reformat the old drive and lose everything. once the new drive is formatted for mac i can't plug it into a pc to transfer the files from. which is the only problem now. but formatting the drive for mac only DOES work. but you're just screwed and not able to use it ntfs. hope the link helps SOME people.

USB Hard Drive not showing up in AirPort Utility

I have been using this AirPort Extreme for over two years now and it's been working fine. I finally decided to buy a self-powered USB hard drive so I can share it over the network. However, after I unpacked the hard drive, connected it to my Mac and reformatted it to HFS+ Journaled and GUID. I plugged the hard drive into my AirPort Extreme's USB port and waited. I looked in my AirPort Utility and saw nothing in the disk list.
I spent hours searching online and discovered that I am not alone in this problem, although solutions are rare. I did try one solution where I hooked up the USB hard drive to a powered USB hub and the hub into AirPort Extreme. It actually worked once and after I rebooted everything, even though the hard drive still showed up in the disk list, no computers can connect to it. Although if I connect the hard drive directly to a Mac, it would still work perfectly.
Having a USB hub is not a long term solution not that it's working anymore anyway. I would appreciate any suggestions you may have, thanks!

USB Flash Drive not detected after OS X Mountain Lion installed.

My MacBook Air 11 inch (Mid 2011) suddenly stopped detecting all my USB flash drives a week after upgraded to Mountain Lion.
I have a tiny 16GB USB flash drive (Sandisk Cruzer Fit), for daily work, that has never been unplugged from my MBA.
Everything was fine on Lion, and a week of Mountain Lion, until just when my MBA prompted me that my flash drive "was not ejected properly" after I re-opened the display/lid, or from sleep mode.
I thought I might have accidentally removed the flash drive unknowingly. So I tried re-plugging the flash drive, closed and re-opened the MBA lid, and the same error message "The disk was not ejected properly" occured. I repeated the steps for a few times (thinking my flash drive might be faulty) and at my last attempt, the flash drive was stopped detected. I tried several USB flash drives and external hard drives (of various brands) to both the USB ports of my MBA, only the external hard drives were detected (on both USB ports) and functioning. None of the flash drives was detected on either USB port.
The tested flash drives were plugged to another 13" MacBook (Unibody, Late 2008, OS X Lion) and they all worked fine.
I wonder if anyone faces the same problem, and solution(s) please?
Additional: OS X Mountain Lion re-installed and same problem occurs / No problem with OS X Lion.

I had the same issue after installing Mountain Lion from the App store. The issue is you are missing the IOUSBFamily.kext extension amongst others. The solution is to backup your macbook, then perform a clean install of Mountain Lion.
I had this done at the Apple Store and now everything is restored as well as performance speed being improved.
Note: When restoring your files (a clean install will delete all your files and applications), use the Migration Assistant.
I would recommend going to the Apple Store to do this because they can perform the clean install from a USB which is so much faster than the download form the App store.
Hope this helps.

External USB hard drive not being recognized

Hello! I'm sure this has been posted before, but excuse my naivety with this sort of thing...
I have a mac mini 10.5.6 (1.83 GHz Intel Core 2 Duo) and I run the Time Machine function to an external usb hard drive. The hard drive worked fine (plugged into the usb port on an older keyboard), but I went out and bought a new aluminum apple keyboard (because they look so cool ^_^ ) - I plugged the external usb drive into the keyboard and it wasn't recognized, so I tried plugging the external drive directly into the mac mini, but it is still not recognized. It is not showing up in Disk Utility or in System Profiler
Help? I'd hate to have to give up this fancy keyboard...
Thank you!
Dr. E

I believe I had my external drive plugged into the (old) keyboard because with the old mac that I had didn't have a free usb port for it - so when I got the mini I just plugged things back in where they were. But I have always had the Time Machine back up to this drive (connected to the keyboard) though it has been slow (another reason I thought the new keyboard was a good idea).
I tried restarting the computer without the alu keyboard plugged in, but same problem of no drive showing up.
Here is what System Profiler has to say about my drive:

I don't know the brand or model as it has 'always' been in the case that in which it currently resides and I didn't physically buy the thing :\ I do know that no software was installed with the drive as I assumed that when I put all the old info from the original mac to the mini that it was the sort of thing that would carry over.
Sorry I'm not terribly helpful - Thank you!

Hard Drive Not detected after replacing DC In Board

So after more than a year of jiggling an easliy bent AC adapter in the port to get my ibook G4 to charge it just quit and would not charge. I suspected it was the slightly loose DC in port (having no idea what was behind the little hole) so I took it to the Genius Bar at my local Apple Store where they confirmed it was likely the DC in board. I was told that just sending my little old ibook away to get fixed would cause an exorbitant $330 just to ship it out, never mind any parts, etc. It was suggested I just buy a new macbook and be done with it. But we've been through a lot and I didn't want to just toss her away so I found a DC In board and replaced it myself. Parts and directions courtesy of ifixit.com
So the part is working well enough that it detects the new AC Adapter (this one new and unbent), which is great. Now I have a slightly larger problem and that is the dreaded little finder/? flashing icon that comes up when I start the computer. It won't start in safe mode. I can't find the original disks (Panther OSX) that came with it. I popped in my Tiger Install Disk and that (Thankfully) came up so I was able to open Disk Utility and lo and behold no hard drive was detected. Just the optical drive and the Tiger DVD.
I was so careful! Did I poke the Hard Drive or something? Is she mad at me for opening her? If anyone has any advice on how I can repair this myself please let me know. I'm desparate to have my baby back.

It's possible that something was disrupted during the repair. You might go back to the ifixit site and look at the instructions for replacing the hard drive. You want to try and see if somehow you disconnected it or something like that. There's a good chance that it is something simple that you can fix. Looking at the pictures might trigger a memory of maybe something taken loose and not reconnected. And try to find your original discs--you will need them.
Good luck!

2.5" external USB hard drive not recognized by my iMac

I have a small 2.5" external USB hard drive that my intel iMac will not mount or see. My 12" G4 Powerbook sees it fine and it is formatted in Mac OS Extended. My iMac is bootcamped and XP on my iMac sees the drive but not OS X Tiger on the iMac, (wierd) I have Tiger on both my Macs too.
Why does the intel based OS X refuse to see this external 2.5 HD. It sees a 3.5" USB one I have but not the small one. I know it is software.

Hey coby,
Well thanks for the star. Not sure I deserve it.
i then tried connecting the drive to each USB port again, and voila! i have found one it works in. I guess my computer's ports must be a little worn.
Hmm well try looking inside and see if there's some smutz in there, if the contacts are dirty or bent or worn.
i was starting to think i would have to go out and get a USB hub to give it some more power.
Is it powered off the USB? If so that actually might be a good idea since that puts a lot of strain on the connectors. Even if it's self powered it might be a good idea since it would take the strain off an obviously flakey USB.

Hard Drive not detected through SATA, but it is through USB.

This week my hard drive seemed to crash, I got the file with the question mark and it wouldn't show up in disk utility. I went out and bought a new hard drive, popped it in and it too doesn't show up. I put my old hard drive in an enclosure and plugged it in through USB, and my macbook starts up just fine that way. What could be the problem?

Well I know the drive is fine because I can run it from the usb enclosure, but is the sata cable going bad a common problem?
Not common but I've seen it happen more than once so I wouldn't be surprised if that is what's going on with your computer.

Pavilion g6 1378sa Hard drive not detected!!!

Hi all,
Im new on the forum and really need hellp.
Let me explain:
One day my notebook didnt start as normal...kept asking to repair the system,I have tried a few times and it still didnt fix the problem.I have 4 x 360 HDD spare ones at home so I removed the old one and I installed one of the spare ones...turn on and no HDD found ( no boot device found) so I downloaded the HP drivers (Seagate Hard Drive Firmware Update) and installed from USB drive,after restarted the HDD was found..so I started to Install The OS (windows 7 Home Premium x64) and all Installation gone without problems.Have downloaded all drivers from HP website and i have done OS updates...turned it off and back on ... after 5mins the screen froze and blue screen comes on!!! The notebook rebooted and ...NO HDD FOUND!!! OMG yes again.I switch it off and back on..reset the bios to factory and the HDD was found....but after 5min again same problem as above.I tried 4 different HDD and it stops during OS installation or no HDD found.
Basically notebook can find the HDD or if I get to install the OS after several times it will drop the system and is no longer HDD available.
I really dont know what to do...never before I met problem like this.
Hope you will not get too confused on my post.
Please comment or ask more questions if needed will answer as much I can.
Kind Regards
Adrian C.

Hi,
We won't concern about RPM, faster (more rpm) is better. The HDD's are much, much, much, much cheaper now. They were more expensive during a flood in Thailand few yours back. Yes, you can use WD HDD for your computer. You can pick one from the following list:

Seagate Hard Drives not detected by the Windows 7 installer

I've spent hours on this trying every conceivable reason, so I apologize in advance for the length on this post.
I connected a Seagate 320GB 7200.10 hard drive to a P35 chipset system and attempted to install Windows 7 RTM onto it. The installer got to the part of detecting hard drives, but could not detect this drive. Native SATA mode was enabled, and AHCI was enabled.
I disabled Native SATA mode, then after that failed I also tried disabling AHCI by setting the controller to IDE mode. Still, the Windows 7 installer refused to detect the drive.
I replaced both the SATA & power cables, verified the drives are detected by the AHCI firmware and the BIOS, and I even tried different motherboard SATA ports to no effect. I took a second , identical Seagate 320GB SATA hard drive, this time pre-formatted it inside Windows 7 RC using NTFS defaults, and again (with and without AHCI and Native SATA mode) Windows 7 will not see this hard drive either!
I even downloaded the AHCI preinstall drivers and loaded these using a flash drive. When I did Windows 7 would autodetect the ICH9 driver and I would click Next. Windows 7 would suddenly see the drive, but all options to format or create a partition are grayed out. Clicking the more info button gives me this error message:
"Windows cannot be installed to this disk. This computer hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer's BIOS menu."
I used the AHCI preinstall drivers specific for the motherboard (Vista 64) and I also tried the AHCI preinstall drivers from Intel for Windows 7 RC 64. As of this writing Intel has not released official Windows 7 RTM Intel Matrix Storage Manager drivers.
In frustration I installed a SSD (with AHCI and Native SATA mode enabled) and suddenly Windows 7 detects the SSD without needing to load any driver (as would be expected, since Vista and 7 include Intel Storage Manager drivers by default already). I installed Windows 7 RTM 64bit onto the SSD without issue.
15 minutes later I was at the Windows 7 desktop, and Windows 7 was showing the Seagate 320GB hard drive under "My Computer" as normal. I could even use the Seagate hard drive as normal as if nothing was wrong. For kicks I launched the Windows 7 installer inside Windows 7, but as you can see below it still refused to see the drive, despite the drive being shown under My Computer:
(Since I can't use thumbnails, here's the direct link: http://i111.photobucket.com/albums/n129/Chanur64/Box/Howpossible.jpg )
Also I should note I previously had Windows 7 Beta installed on an IDE drive in this exact system, and had no problems with it. Windows 7 RTM would allow me to install to an IDE drive and allowed me to install to an SSD, but it cannot see and cannot install onto both Seagate 320GB hard drives. These Seagates are known good drives previously part of a RAID 5 array.
If anyone knows what is going on or has some ideas I've not tried I would love to hear from you and get this figured out. Suffice to say this is not a promising start for Windows 7.
Intel Q6600
Gigabyte GA-EP35-DS4 (ICH9R southbridge)
4GB DDR2-800
2x Seagate 320GB SATA 7200.10
Intel X25-M 80GB
8800GTS 320mb
PC Power & Cooling 750w PSU

I just had to solve the same issue with a Seagate Momentus Thin hard drive (
http://www.seagate.com/www/en-us/products/laptops/slim-laptop-hard-drives/)
Tried several BIOS configuration, AHCI drivers, etc and Windows 7 32bits couldn't detect the drive.
My solution was to boot with a USB pendrive with HirenCD tools (http://www.hiren.info/) and use a partition manager to erase disk contents, create and format a partition.
Windows 7 detected the hard drive for the first time and now is installing, so.. crossing fingers.
Thanks,
Diego
Diego,
Thanks for the information and the link to Hiren.info! I'm creating my bootable flash drive now. I'll report back if I get this to work.
I had this same issue on a Seagate Momentus 7200.2 "laptop" hard drive. I say "lap top" in quotes because it's actually in a desktop (HP Compaq Ultra-slim dc7800). I believe it was an upgrade, so it took me a while to figure out what I was dealing
with until I finally took out the harddrive and checked what company made it!
Thanks everyone!

MacBook Pro 13" 5.5 (mid 2009) new hard drive not detected

Hi,
New here, tried searching for the answer here but could not find any.
I got a few hard drive error on my old macbook black 250gb drive that I put in this MacBook pro.
The system became really slow and kept hanging (beachball).
So I went out and bought a new 500gb WD Scorpio Blue 5400rpm.
The problem is that my MBP doesn't detect the new HDD when I put it in there (doesn't even spin up when correctly put in). It does spin up when only connected to the sata connector but still no detection.
When I put it in an external USB cradle there is no problem.
Also found out that way that the old hdd works fine when booted from the USB cradle.
Does anyone here have any idea what the problem could be?
I'm starting to think it's the controller, but that would probably mean I can go out and buy a new MBP...
Allart

Could also be a bad cable...make an appointment at an Apple store. If the cable is bad, should cost less than $20 to fix.

External USB Hard Drives Not being recognized since recently.

Some quick facts:
Using early-2011 MacBook Pro, 15"
Two HD's worked fine recently (around before upgrade to Mavericks):
1 Lacie Neil Poulton 1TB Disk
1 Western Digital MyBook 500GB Disk
BOTH were formatted to Mac OS Journaled since day 1, so NO bloatware/manufacturer software. Purely storage.
The 2 drives are connected via a powered USB hub, but connecting it directly doesn't help. (strangely, the keyboard and mouse attached via USB hub work fine)
Tested with 7 different USB drives to test– none of them work
The 2 drives actually show up in the System Profiler, but not in Disk Utility.
Both Hard Drives work on my 2012 Macbook Air 13" (running on Mountain Lion) absolutely fine. Tried the 7 USB drives– they all work as well.
Tried SMC reset. Briefly detected the drives, but once I put it to sleep and turned it back on, it stopped detecting it again.
Help!!!!!

Both Hard Drives work on my 2012 Macbook Air 13" (running on Mountain Lion) absolutely fine. Tried the 7 USB drives– they all work as well.
Yes, youre having a problem with WD software and firmware, this has been a point of much discussion with WD software and Mavericks , and affecting drives OTHER THAN WD, via their software
you can read about it here, and ask WD about their removal software

You can now download the WD Software Uninstaller. This utility will remove Mac WD SmartWare and WD Drive Manager software. You can find the uninstaller under any of the Mac Drive Downloads sections such as the My Book Studio below.
