Hard Drive Shows In Device Manager?
Dec 15, 2011
I've spent most of the night searching and cannot seem to find an answer to my problem.I have a NAS set up with two 2TB Samsung Spinpoint hard drives. The hard drives in the NAS were partitioned to have 300GB in a RAID 1 and the remainder in a RAID 0. One seemed to be failing so I removed it hoping I could connect it externally to my laptop and recover the data. When I hooked it up to the laptop, it seemed to connect fine but did not show in My Computer. When I went to Computer Management - Disk Management, it shows the partitions as healthy (see image - Disk 1). However, when I right click on the partitions to assign a drive letter, the only options available are Delete Volume and Help. Same when right clicking the Disk 1, all that is available is Convert to Dynamic Disk, Properties,

I just bought a new ASUS computer with Windows 7. I have a Macbook Pro and would like to transfer my photos and music onto my new computer. I have 2 external hard drives that work perfectly fine on my mac as well as other PCs. When I plug either of my external hard drives in they are recognized in device manager and say they are working properly but are not recognized in disk manager or under my computer...

Have recently purchased a small usb inspection snake camera with led light and when testing it plugged it into two desktops computers (one xp pro not sure of the other as it was a network work computer) It automatically loaded the drivers and brought up a screen automatically with the realtime image.(no driver disc came with it). However plugging into my windows 7 64bit sony laptop it signals a connection beep, loaded drivers automatically but wouldn't open or show up on my computer disc manager as an external usb source to click on. It does however show up on device manager as a usb camera and when I unplug and replug in it disappears and reappears so I know I have the right camera (not the lap top webcam inbuilt one that shows USB 2 Camera). Have tried updating drivers automatically and uninstalling it etc. Need it to work on the lap top so it can act as the movable screen for it?

I was normally using my computer, when I suddenly noticed one of my hard drives disappeared from My Computer. Checked the Device Manager, I get the following. Trying to initialize it throws up this error: Seems to spin just fine. Trying different USB ports failed, switching cables as well. Already tried a few programs. GetDataBack for NTFS throws up error 1117. R-Studio also fails, as does DMDE and MTY. My friend even borrowed me Microsoft DaRT (part of MDOP), but when I boot into it, it doesn't recognize the HDD at all, no matter how hard I try. Only my Windows 7 installation does.Anything I can do in this situation? I had a lot of important data on it, and it's not completely dead yet. Maybe I can still save it somehow, without haivng to pay one of those data recovery thieves...

I have completely formatted my hard disk with seagate seatool. Then I have installed windows xp sp3. I have made 4 partitions at that time i.e. c,d,e,f. After that I have installed windows 7 now I can't see my hdd in disk management or in device manager. Both device manager & disk management are showing me my external drives like pen drive.

Because windows gave me the blue screen of death yesterday, I had to reinstall, now it won't show my second laptop HD. During the install, I partitioned both drives, and it detected them, now it only shows my 1 HD with the windows directory in it. How do I solve this issue?

I am a salesman in a tech department of an office supply store, and I had a customer issue stump me today. She had an external drive with lots of files on it she wanted to access. I took the drive, plugged it into a Windows 7 machine (HP quad), and all of the files appeared, no problem. But, then I plugged the seagate drive into her new Toshiba laptop (also Win 7), and only some of the files appeared. Missing were all photo files, and many other types. I could not figure out why some were missing and some showing. I took the drive to a third computer with Win 7, an MSI all-in-one, and behold: files were missing. Now it seemed almost arbitrary. Could it be a matter of some Windows updates not yet installed? Why would the exact same drive work differently on three different computers in regard which files were seen and accessible? None were "hidden" files.

There is a unknown 'portable' device (F:/) on my computer which I dont recognize. I saw it when I was about to scan my computer with Norton and was about to select which drive I wanted to scan, if I show hidden files it also shows up under My Computer, but I cant access it.... What could cause this?

I have Win 7 Enterprise installed.
When I click into my IE8 Favorites, my HD folders are appearing there. I did some tests and if I try to delete them, my original HD files are deleted.
Maybe it happened when I tried do bring back my favorites from my backup files (ex Win XP), and I think that IE8 added all folders of my c: hard drive instead of only my favorites bookmarks.
Now, I can't even add new bookmarks.
Please my friends, is there anyway to fix that?

I have a Western Digital 1TB Hard Drive (External).I use it 99.9% of the time on my Windows 7 64bit computer to store pictures/videos and backup important files.It was working fine until I plugged it into a MACINTRASH to backup files from that computer.It was a simple copy and paste from the MACINTRASH to the External HDD.After copying the files from the MACINTRASH, I plugged it back into my PC.My PC no longer recognizes my external HDD. I unplugged the power, plugged it back in.Same with the USB cable. Rebooted. Then my computer wouldn't reboot and windows did its automatic self repair. Nothing.I unplugged EVERYTHING and left it that way for about 30 minutes. I plugged EVERYTHING back to my computer and turned it on.
Windows booted up fine. I plugged in the external HDD and windows had that little icon telling me it was installing drivers. I was excited to think that it finally would recognize my external HDD.Of course, it didn't work. The HDD does not show up in my computer. It does show up in Device Manager and Disk ManagementDevice MangerUnder Disk Drives it lists it only as "WD" My other drives it has a nice long name like "WD 7500AAK External USB Device" Under properties it tells me Volume information for the disk cannot be found. (The very first time I did that prior to the reboot it said there was 0MB of space on it). It claims the device is working properly Disk ManagementAt first this said that I must initialize my disk. Now it doesn't even show up anymore. I have no idea what to do anymore.

My portable hard drive is showing all the hidden files and folders on it (the ones prefixed with ".", but not the System Information folder, interestingly). I don't have this trouble with any other drives, or elsewhere on my computer, so it seems somehow to be associated with this specific drive.Of course I check to make sure that "Show hidden files and folders" is turned off.

I have a 500gb seagate external hard drive, and already used 240gb space. It worked fine until yesterday suddenly i could not access the files at all. I checked disk management, and it showed that my external drive became RAW drive. I tried to do chkdsk that I learned from one of the forum, and then it somehow has fixed the RAW drive back to FAT32. However I still cannot see any of my files. I opened command prompt, and typed in dir /a and it said 0 files 0 bytes, 4 DIR 288,714, 293, 248 bytes free. How can I bring my files back?? I don't want to lose my files.

First I want to say that the drive works without problems at the correct speed. The problems come upon disconnect. I also want to to stress that USB 2.0 discs are working flawlessly. If I use safe eject and the look in the device manager I get an error 47 saying that it has been shut down but not disconnected, it also says I can rectify it by disconnecting and reconnecting but this does not work. If I do so the drive will not be recognized. The enclosure has a power switch. After a safe eject I have tried both pulling the USB cable while power is still on and also going the other way by first shutting the power down. In both cases the error 47 shows in device manager. When this happens the CPU load goes up to about 20% and stays that way when it before was around 0 at idle. If I reboot the drive reconnects and I have no problem with it unless I try to safely eject it again.

My C: drive has been displaying a size of around 60 gb with 40 free even though it's a 300 gb drive. I thought the issue would resolve with a clean install, so I did that. Now I have a fresh install and i need to reinstall everything, but the problem isn't fixed. Below are some screen shots of the drive size:Disk Management, showing my C: Drive's full size ^Any suggestions of how I can reclaim this space?? I've tried a few things already to no avail. If you need any more information about my computer to help, let me know. This is pretty annoying, 'cause I want to use that extra space to install Ubuntu.Oh, I just rememberedWhen I look at the drive in Paragon Partition Manager, it shows the full Drive size, but says that the space that is missing from Windows is in use...

For the last few days I've been running some CPU intensive programs which I wrote. My laptop was getting really hot (70+�C), so I decided to blow into the vent to clear the dust out. However all this did was clog the fan with dust and it stopped spinning, so I used a safety pin to hook the dust out. The fan started spinning and it blew a load of old dust out, and my laptop is now running in the low 40's.
However now task manager shows the CPU usage as 100%, but when I sort the processes by CPU time, nothing is using much of the processor, firefox sometimes jumps up to 50%, but it doesn't stay there for long.Even when I boot into ubuntu, everything is still running really slowly.Also, speedfan reports my CPU speed as 600mhz, sometimes it shows a few other values (1400, 1200, 1800 etc), I have two core2 duo 1.83 ghz processors, so I wasn't expecting to see 600mhz!

I originally had been running windows XP on my desktop. About a month ago, I bought a new hard drive and installed Windows 7 Ultimate x64 on it. For the last month, I have been able to dual boot between Windows 7 and XP just fine.
When I tried to boot up my machine this morning, my computer no longer boots and have the following message on screen:
"Reboot and Select proper Boot Device or Insert Boot Media in selected Boot device and press a key"
I checked my BIOS and found that only my new hard drive and CD ROM are detected. I imagined that my old hard drive with Windows XP on it finally died. So I disconnected the old drive, but I am still getting the same issue. I have tried changing the boot order. I also tried booting with the Windows 7 setup CD and tried the repair tools. None of them recognizes the Windows 7 installed on my new hard drive. I started command prompt and was still able to see the contents of the new hard drive, with its WINDOWS directory and all my data/installed programs, so I believe the new hard drive still works. Is there anyway for me to fix this without having to reinstall Windows 7 again and lose all the data/programs I have? Does this have something to do with my XP not being bootable anymore?
OS: Windows 7 Ultimate x64
Motherboard: Gigabyte GA-Z77X-UD3H
Harddrive: Seagate Barracuda 1TB 7200RPM 64MB SATA 6Gbps

I have a LaCie external hard drive which works fine on other pc's running Windows 7 Ultimate, but on this one it is an "unknown device". I have tried it in different ports but with the same result. I've checked with Windows Compatability and the exact model is listed there as being compatible. I've been to the manufacturer's website but there are no drivers available.I have the same problem with any USB device I plug into any port. I have tried a complete Windows re-install from a different CD but it made no difference.The only USB devices that work are the keyboard and mouse.I have given the LaCie HD as an example because I am hoping that if I can get a specific device to work, I may be able to solve the problem with others.

How do i figure out what driver or even component windows wants software for when in the device manager under other devices it lists an unknown device and windows update cannot find anything.
Oh and is it appropriate for me to use this topic to ask another question regarding explorer.exe as while i am inside a folder i delete (by choosing delete from the context menu in the tree view) while inside that folder on this particular laptop PC explorer. always crashes, collect information, sends it and restarts explorer. I have not experienced this problem on any other pc running any version of windows 7, oh and the same happened with build 7264 x32 and the current install of build 7600 x64.

I've got this problem 2 days ago where my PC started slowing down and i've been getting random BSODs mainly "Special Pools Detected etc & Memory Management" When i start up the PC its slow and it takes alot longer to just open even a folder. I've tried searching for such problems and i've tried almost everything i know to try and fix this but i guess i'm still in-experienced when it comes to problems like this.It happened 2 days ago after i played an online game i got a BSOD and couldn't remember what it was. So i restarted and the problem started. The most recent hardware change was that i changed my RAM from 4gb to 8gb and nothing else. I did not install any new programs recently. So initially i thought it might be the RAM causing this problem so i changed it back to the ones i had previously. Here are the specs of my PC. [code]
Anyway i've scanned the PC using Avira, Spybot & Avast and there were 0 findings so i hope i am right to assume that my computer has not been infected with malware/spyware. But still in the task manager, the CPU Usage % and Memory Usage shoots up whenever i do any sort of action, eg. Refresh on the desktop, Opening a folder, Opening the browser etc. I've tried booting into safe mode. And the CPU usage was minimal compared to normal but i couldn't detect what was causing this problem. In the task manager, explorer.exe & svchost.exe were the top memory users. I've tried msconfig, disabled all the startups, but still i am having the same problem.

I have a 3 Tera HDD. (WD My Book Essential (USB 3.0)). Last night I uninstalled a software which I do not remember its name by mistake. Apparently it was related to my WD hard drive for my computer does not recognize it anymore. I checked my device manager; "Base System Device" is not recognized. I ran windows troubleshooting. It says "Base System Device" Driver is not found. I searched a lot, but I couldn't find the driver. I also ran drive checker software.
It says:
Device name: JMB38X SD/MMC Host Controller
File name: MSI_GX633_Card For Windows 7.zip
Hardware ID: PCIVEN_197B&DEV_2382
I could not find this too. I also have another portable WD which is still recognized by my computer.
