Q: Computer doesn't detect external Hard Drive

I use 3 computers, in one that has Windows Seven and other Xp, the computer detects the external hard drive with no problem
But in another Windows Seven pc, it doesn't detect it at all, the hard drive makes a clicking sound and nothing else

So, what can it be?, I even connect it to a TV and can watch movies with no problem, but being detected in that computer, never

Preferred Solution: Computer doesn't detect external Hard Drive

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Do other external drives work with that PC?

Does that external drive appear in Windows Disk Management? If it does, does it have a drive letter assigned? If not assign a drive letter.

So i want to switch the HDD's of my 2 computers, i unplugged both drives, then i put one of the drives into the other computer attaching it exactly as it was (the master slave thingy) but the comp said it didn't detect and master or slave. So i took it out again and changed the master slave thingy so that it was the same as the HDD that i took out of the computer i was trying to get this HDD to work in.

Same thing happened, comp said it didn't detect any HDD at all.

Why can't it detect it?

Both drives are unformatted and have windows and stuff on them, i thought it'd be a simple switch a roo.

Does this mean that the HDD is not compatible in this other computer?

Or do i need to do something to make the computer detect the HDD?


A:Solved: Computer doesn't detect hard drive

I assume they are not being seen on the bios - correct

check the details on the HDD and make sure you have set to Master - what else is on the cable .....

are these identical machines ? because with windows you have installed all the motherboard drivers and even if you swap them around and get the bios to recognise them - windows may not work correctly

Hi guys,

I've had this 3TB hard drive for about 6 months with no problems.

However, for some reason my computer cannot recognise it any more.

It doesn't come up in My Computer, but it comes up in device manager ( see pic 1) and in disk management (see pic 2)

Alarmingly, I can't even assign a letter or do anything but delete the volume (see pic 3)

I can't find the driver cd to install it but I didn't think this would be a problem as I installed it anyway through the computer. I've searched for about 2 days on this forums and others and still can't find a solution. I hope I can find one here

oh and i forgot to mention, i tried the hard drive on two different computers and it had the same problem there as well.

I had my WD external hard drive for more than a year now, and it worked fine until today.

My laptop suddenly won't recognize my external hard drive.

I have two USB ports and they seem to be working just fine; I've tried with different devices.

I plugged my external hard drive to my friend's laptop, and that worked fine...so I have no idea what's wrong.

The LED light on the hard drive stays lit (very few or no blinking) and there's no spinning or ventilating sound at all.

Seems like only the light is on without the device actually working.

Could anyone help please?

Hi, I've just bought a Formac 250gb usb 2.0 external hard drive from ebuyer but when i plug it into my machine it's not recognised in any way other than under 'safely remove hardware'.

It's not shown under my computer or in disc management. I've tried plugging it in different usb slots (all of which work fine with other devices) but no luck.

When i first hooked it up the little bubble came up in the bottom right corner sayin 'found new hardware' followed by 'your new hardware is now installed and ready to use'.

I tried plugging into a slightly newer computer and it works fine so the problem must be somewhere on my machine.

I'm running XP SP2 but i heard somewhere that older (slower) machines can't register large external hard drives. I'm only running an AMD 1.21GHz processor with 384Mb RAM. Is this too slow or is there something else that it could be? There are no mimim system requirements on the box / instructions etc.

Any help would be very much apreciated!

I'm using a Gigabyte GA-EP35-DS3R motherboard, and my hard drive is a seagate barracuda 500gb.

The system is brand new, built myself. No previous operating system on it.
I tried installing windows vista. I get past everything, until it asks me to select a drive to install to, and the list is empty. I tried every driver on the mobo's cd, and every driver on their website, none of them worked. I've tried different SATA modes, and ports on the mobo, and it doesn't work (I would dear say I've tried everything, except another OS because I don't have access to one).

However, when I select browse to search for drivers, when installing vista, I can select the local drive and search it for drivers. Does this mean it's there and it's something else, or is it just an option and what not? (there's a floppy there too, but I have none installed on the computer).

My bios sees the HD just fine. I'm out of ideas, and friggin fed up. I tried contacting Gigabyte but that was pointless.

A:Dell XPS L321X does not detect external usb hard drive

Hi Ashim,
Please try connecting the USB drive into an alternative USB port and see if it helps. You may also try using an alternate USB device such as mouse, flash drive etc to verify the functionality of USB ports.
If the USB ports are not working properly, you may follow the steps below to uninstall USB root hubs and restart the system :

Unplug all USB devices from the computer.
Press Windows + R button on keyboard
Type 'devmgmt.msc' without quotes and press Enter
The Device Manager window will open
Click on > sign next to ‘USB Universal Bus Controllers’ to expand the category.
Right click on each entry listed under USB Universal Bus Controllers and click on ‘Uninstall’.
Click on ‘Yes’ on the security warning.
Restart the computer and Windows will automatically install generic drivers for USB Root Hubs.

If the issue persists after refreshing USB root hubs, you may update the chipset drivers from Here -> Enter the Service Tag of system -> Click on Drivers and Downloads -> select the operating system installed on your computer -> Expand the 'chipset' category and download/install the drivers -> Restart the computer when prompted and check if the hard drive is getting detected.
If you have any questions, please share the system model along with the Operating system installed on computer. Will take it further from there.

Hi there,

I need some good advice here, I hope someone can help me.

I just bought a usb3.0 320gb external hard drive the brand and model are: "Imation Apollo M100"

I plugged it into a usb 3 port and it worked but I wanted to format it before i used it, so i right clicked on it in my computer, and clicked format from the drop down box.

I selected quick format and then started it. It ran for a while, then a box popped up saying: unable to complete format" or something to that effect. after that it was inaccessible. the drive showed in my computer as "local disk H:" or something like that. there was no gauge below it indicating the amount of data remaining on the disc, like all the others (ie: "30gb of 465gb left" which is displayed below my internal hard drives)

from the control panel i went to system & security -> create and format hard disk partitions. in disk management it was there with a 1mb partition and the balance of the space as RAW. so i deleted it and tried to format it again with the same result (minus the 1mb partition) i unplugged it and tried the process again, this time i unchecked "quick format", and still no dice.

now it wont pick up at all... i hear the ding dong when i plug it in, but it doesn't show up anywhere, in my computer or in disk manager.

Has anyone got any idea whats going on or what i have done wrong? im normally able to figure this stuff out but im completely stuck... ... Read more

In the Device Manager window, find the item/items labeled "Universal Serial Bus controllers." And expand.
Now plug the device in. Do you see a USB mass storage driver appear under USB?

3. Also do you see any devices in Device Manager listed as Other or Unknown, or having a yellow symbol?
If so right-click and Update.

Hi everyone, this is my first time here.

I could hear it wind up but then it would stop so I went to 'my computer' and my D drive wasn't even listed there. I haven't used my D drive for a couple of months, so who knows how long this has been a problem. I had the klez virus back in July but then got rid of it. I don't think that caused the problem because after I got rid of the virus I reinstalled Norton and it worked just fine then. A couple people have mentioned that it coule be a lost driver but I don't want to waste time downloading programs that I don't need. Any thoughts?

I don't know if this is the right forum for my problem.
I had a new desktop pc built about six months ago and it seemed fine except for one thing. The Seagate external hard drive had stopped backing up despite being set to continuous. It had worked perfectly on my laptop which the desktop pc replaced. Not knowing what I was doing I not only uninstalled Seagate but formatted it too resulting in the loss of everything.
So I bought a Western Digital My Passport external drive, plugged it in and it backed up. Since then, though set to continuous back up, it just doesn't do it. Nor does Dropbox. Data files are just not being updated though WD and Dropbox say they are up to date. Manual updating works. I feel sure the problem is not with the external drives but with the Microsoft system, that there is a box somewhere that needs changing. Can anybody give me any clues please? If I'd wanted to do a manual update every day I'd have stuck with a USB stick.
My system is a 64 bit Win7 and I have plenty of memory. I run Firefox, Bit Defender (I recently changed from AVG) and Malware Bytes.
Any help would be appreciated.

A:Windows doesn't recognize my External Hard Drive

I"ve had a Simpletech external hard drive for a few years now, and it's worked great on every computer that's had Windows XP (it's a plug and play). However, I just bought a new laptop with Windows 7, and when I tried to plug it in to the USB port on it, it just told me "USB device not recognized." The power light comes on, too. This is a brand new computer, so I'm not taking it apart to reassemble anything, and the external HD still works fine on my XP computers, so I know it has to be something about Windows 7 it doesn't like.

Check your device manager and make sure that your USB drivers are up to date...

I have a Toshiba EHD 300GB.. When I first connected it, it had its own unique icon.. I decided to format it and now it's icon is a plain white sheet with little squares .. I've tried doing the procedure in this link (Drive Icon Change - Vista Forums) but it still didn't work. I'd love to show you what it looks like, but I don't know how to paste the image I captured.

I've tried renaming it, but that doesn't help. It doesn't even want to be renamed.

I was thinking if there's any other way we could return that unique icon it had and rename it other than the link I followed above.

My EHD works perfectly. I'm just bothered as to why I can't change the icon and its name. Thanks in advance for your advices..

A:External Hard Drive name and icon doesn't change

Hello Paxnominus,

For Windows 7, you might use these tutorials instead.Drive Icon - Change


Drive - Rename
Double check the item in the yellow TIP box at the top of the tutorial to see if you may have a autorun.inf file on the root of the external drive that needs to be deleted.

If Option One did not work, then be sure to also try Option Two as well.

Hope this helps,

I have a External Seagate 2 Tb hard drive that after a while, will disconnect and I can't wake it by trying to access the drive in Explorer. I tried rebooting my computer but it doesn't show up anymore. The only solution it seems is to disconnect the drive and plug it back in.

Any advices?

I've really gotten on this.
From my computer I can access my external hard disk, but when I go to create a recovery image the computer doesn't see the external drive.

Is there a setting somewhere I can change?
All my searches tell me about reading the backup from a non detected drive not saving onto a semi detected drive.


A:Location backup doesn't see my external hard drive

Hello windam and welcome to Seven Forums.

It might help to diagnose the problem if you could post a screenshot of your maximized Disk Managment window. It's possible the external drive doesn't have a drive letter assigned, or some other issue.

I have a 250G Maxtor external hard-drive which I took from the shelf and plugged in last night for the first time in several months. At first I noticed the light blinking erratically and also heard a constant clicking sound, the same sound over and over. I disconnected and then reconnected it, and this time the unit worked okay. I was able to access the contents. Later I disconnected and reconnected it several more times, only to find that it no longer works. All I get now is the unending clicking sound.

As far as I know it has been setting on my shelf for three months or so. To my knowledge it hasn't been moved, much less dropped. Assuming that it is irretrievably broken, are all external hard-drives this fragile? I thought I had been storing my stuff relatively safely -- as long as I didn't drop the unit. Maybe I was wrong. I would greatly appreciate hearing from anyone who might be able to help.

System: Win 7 Home, SP1 with latest update.
Hard Drive: Seagate 3 TB external hard drive. Automatically turns on, no power switch.

Here's the problem. My external hard drive no longer wants to play nicely with my laptop, or vice versa. Now, I have my mouse plugged into one of the USBs, (doesn't matter which one, I move it around) and it works fine. Flash drives, same thing, no problem. Same with both of my game controllers. Never a problem.

I go to plug in my external hard drive, and either it will come on for like 60 seconds and then go away, or it doesn't come on at all. However, if my husband plugs in my external hard drive to his computer, which, by the way is the exact same as my computer, both laptops of the same brand and model, it comes on within 10 seconds and stays on.

My external hard drive USED to work on my laptop just fine. And, my smaller (1 tb Iomega) external hard drive works great on this laptop.

So, what did I inadvertently change to make my laptop no longer wish to speak to my external hard drive? I'll bet it's something really simple.

Any help at all will be greatly appreciated, and not argued with in the least!! I promise! (my husband is making me say that. LOL)

Thank you!!
