Hardware Drivers :: Hard Drive Disappears From Explorer Randomly?
Feb 18, 2014
I am running 8.1... recently my second seagate barracuda HDD has just been disapearing from explorer... this is my last resort, after this there is nothing... google is completely useless.. I have bought a brand new sata cable, so thats ruled out, the drive is NOT dead, it works perfectly fine and is 100% healthy. the motherboard is not fried, that was just replaced not more than a month ago. the UEFI BIOS is up to date... basically as i said my drive just disapears.. some days ill be able to see it and access files, the next it will not show up in any program at all... I have tried seatools, it does NOT show up in there... im just about ready to throw this damn drive out the window...

I installed Windows 8.1.
My computer has an SSD which has the installation. My computer has a hard drive with file.
The hard drive shows up on Disk Management. The hard drive does not show up on File Explorer.

I have a windows to go installation in a large external hdd, so I have made a second partition to use as data storage.
Now, when I insert the disk on my "normal" windows installation I would expect the data partition to be available... Instead I have to assign a letter to be able to use it.
The disk appears to be online and once assigned a letter you can unplug it and plug it again without having to do the letter assignment again.
BUT, every time I restart the pc I have to do it all over again.

Something terrible happened to my computer today. I'm honestly not sure exactly how, but my hard drive locked itself. I was trying to install FL Studio 11, when it kept saying I didn't have write permissions. I thought that the installer might be corrupted, so I downloaded it again. It still had the same issue. I thought maybe it was an issue with Windows 8, so I burned it to a USB and connected my iPhone to iTunes to try and sync some music to it before I restored Windows. Not only did the driver not install, but iTunes closed and said I either don't have read/write permissions or iTunes is on a locked hard drive. Frustrated at this point, I turned my computer off and booted from my Windows 8 install USB.
Windows 8 will not install because it says that my hard drive is locked so I can't install Windows 8 on the hard drive. I tried installing it again and the installer said that the temporary installation files could not be copied to the hard drive. I can't boot into Windows now, it just stays stuck at the flashing symbol (I've left it there for about 5 hours now, still nothing). I have a lot of files that I really need for making my music and a lot of unrecoverable pictures, so I really need to get this computer fixed.
At the moment I'm installing Windows on a USB in hopes I can boot from that and move all my files to a backup PC and then format my hard drive, but I'm not 100% sure that will work. I checked my BIOS and my hard drive is not locked with a password or anything, so this just doesn't make sense to me. It might have something to do with all the partitions I've made in the last few days to install Linux and I decided I didn't need it so I deleted the partitions and extended my main partition again.
Also, I've already tried automatic repair about 6 times nothing has worked, it says it can't fix my PC. I fixed this problem by downloading Hiren's Boot CD, going into Mini XP, moving all my files to another laptop with USB, and formatting my hard drive completely.

I have just bought a 4TB external USB 3.0 hard drive. The plan is to copy all of the data from my current internal 2TB drive to the 4TB, then I'm going to crack the case of the external hard drive open, take the drive out, and put it in my PC to replace the 2TB drive that's in there now (which I know will void the warranty). This isn't going to be a boot drive as I have an SSD for that.
I had read that Windows does not support large drives of this size and that it would show up as 2 partitions, so I was prepared to convert the drive to GPT in order to have 1 large partition. However, I connected the drive up to my Windows 8.1 machine and it shows as 1 large partition of 3.63TB, which is about what I expected.
Does this mean I don't have to convert the drive after all? Can I do what I'm planning to do and everything will work fine? Or do I need to convert it to GPT before I copy all of my data over and if so, how do I do that exactly?

I recently discovered that one of my drives has been at 100% activity with no data being read or written. This particular drive is used for virtual instruments and samples for music. I've never had issues before, but I found it odd that loading projects took an insane amount of time to load, which lead me to check the disk usage of this particular drive.
Current response time spikes into the tens of thousands. Again, nothing is being written or read. If I open the drive, I can see all my files, but the drive never seems to stop "searching". I've attatched a picture below:

I just installed Win 8 last night and everything seemed fine before I turned off the computer. Now, I'm a student and I work a lot from my USB/HD. I have both my usb and HD connected to the computer but the computer doesn't read them now.

My portable hard drive stops showing up all of a sudden. It is connected to a USB hub. When I go to 'Disk Management' in 'Computer Management', the hard drive shows up as Unknown - Not Initialised. Also this hard drive works while not using the USB hub, and the USB hub works as well with other devices.

I built my computer a couple weeks ago and am running windows 8.1. I currently have a 128gb SSD and a 1tb internal hard drive (WD Caviar Blue) I obviously used the ssd to boot windows and currently windows is detecting my 1tb hard drive but it is not usable. I have tried diskpart commands to clean and format and I keep getting the error message "DiskPart has encountered an error: The request could not be performed because of an I/O device error". The hard drive was brand new and cables are fine. This is what everything looks like..

I am having a little trouble with windows disk management. I'm running a custom built rig with a 250GB SSD for OS & Programs, and a 2TB HDD for everything else. The hard drive was previously partitioned however I recently removed these partitions and Extended the main volume to fill the drive, however it is showing up as 3 distinct volumes in disk management (See attached screenshot). They're also Green from some reason and the disk is showing as a 'Dynamic' disk, which I don't remember changing.

HP Envy dv7, Windows 8
Seagate 2TB drive mounted in a Thermaltake, Max 5 enclosure. The drive does not show in Windows 8. Does show when running Disk Management (diskmgmt.msc) but shows as "Unallocated" without a drive letter. If run the Seagate drive tools, it shows up as unallocated, with drive letter "C". But there is obviously already a drive "C".
Disk Management does not present a means by which to assign a drive letter

I have a Simpletech Simpledrive External Hard drive. It works on my desktop running xp. When I connect to my Asus N56DP Laptop, I hear the binging and all. But I do not see it in my control panel. I can see it in the device manager. Not in Disc MAnagement. Is there something I can do to get it to install and be accessible? I have some race car pictures I would like to post to Facebook.

a friend of mine recently brought me a notebook,Medion AKOYA 99380(s6214t). After booting and using notebook for some time,computer reported a Hard Drive error.It said:"Windows detected a hard disk problem. Back up your files immediately to prevent information loss, and then contact computer manufacturer to determine if you need to repair or replace the disk."
The HDD is pretty new and it didn't seem to have any hardware issues. However,I did a clean instal of Windows 8.1 on the notebook(normally I installed Windows on the 64GB SD Card located in the "tablet" part of the notebook,so that way a person using it can use it as a tablet,too). Everything seemed to work fine, no HDD errors from Windows etc.,but then I opened My Computer and second Hard Drive wasn't there.I thought that it's a Drive Letter problem so I went into Disk Management however it did not solve the issue.
Then I tried everything(re-formatting,changing from NTFS to other formats etc.) but it did not seem to work.But all of sudden,after doing something, I don't really remember what I did that made the Computer see it, but it finally worked,so I just started testing everything. And after I used it as a tablet only for a while,I plugged that part in the notebook again and then Windows gave me an option to Update and Restart. I was a bit afraid of how it will turn out,so I wanted to shut down and turn on for a couple of times before updating, just to see if it will cause any issues. When I was sure that it worked perfect before the update, I clicked the option to update.
After the update was finished,Windows ran extremely slow and it detected my second HDD, however not the way it should.It only said "Local Disk (D: ) but I could not access and it didn't show how much memory on it was used. I re-assigned a letter to it after a format,but it did not work. Then I shut down the notebook,pull the second hard drive out,connect it to computer with usb so windows sees it as an external hard drive,and bam,everything worked. I don't think that the HDD is the problem,nor the SATA connectors,it's most likely that the motherboards driver need an update. However,when I checked for it's name,it said "Medion AKOYA s6124t". I tried all the downloads from Medion's page,but no succes in finding a proper driver.

I have an external harddrive on a USB2 port that I have been using for ages without problems. Yesterday it just stopped being accessible for no apparent reason. The machine "sees" it (as the F drive) but can't access it. If I try to double click on the F drive the machine takes aaaaaages (green "busy bar" slowly tracking) and then I eventually get an error that says "F: is not accessible" - as per this image:
So I assumed the drive had died. But to test that, I plugged it into my g/f's old XP machine and it accessed the drive with no problems whatsoever!
The only other thing I could think to try was to look in disc management. But even though the is an F drive showing in explorer (as per the above image)... it doesn't even show up in disc management!
So, in exasperation, I did a "refresh" of my system. A bit of a drastic step, but I thought maybe it was time for a cleanup anyway. But, after the refresh was done... STILL the same problem! Exactly as per the above images, the machine "sees" the F drive but nothing is accessible.

I'm currently using a Dell Inspiron 3520 laptop with Windows 8 on it. I have an external hard drive from a Windows 7 desktop. It recognizes the external hdd right away and I can access it but I can't figure out how to boot Windows 7 as the primary. I've tried changing boot order in bios but I've had no luck as it still boots Windows 8 first. Is there a way to use the Windows 7 as the primary drive ? Even a way to temporarly turn off the Windows 8 hard drive will work. I just need to access the Windows 7 hard drive without having to navigate through program files to have to open something.

Other solutions have been to right click and assign a drive, but those listed below other that the C: don't allow.

I have a Dell XPS-12 laptop. It's pretty standard, and I only use it for school. I'm a Computer Science major (which is incredibly ironic in this situation... wow), and I partitioned part of my harddrive off, about 32 GB, for a CentOS and then Kali Linux install, first to run a configuration and write some custom code for an open source captive portal my work has deployed and second for testing my place of employments security implementation (boy was it easy to gather some scary data with a simple wireshark capture..). I am extremely busy with being a fulltime student and also working 2 jobs and freelancing web development, and I haven't been able to figure out why after reformatting the partition I was using for the Linux installs, I could never reintegrate that partition into my own Windows partition. It's incredibly annoying as I only have a 128 GB SSD and after screwing with it for ten minutes, said screw it and just made it into a backup drive where I keep all my code and larger ISO images for different OS' I have (after just a year of studying CS, I've had to use a total of 6 different Linux OS', as well as messing with trying to get an ArchLinux install up and running correctly... I'm starting to feel like a collector)
why my harddrive is being super lame and finish that matrix for the Software Packaging class' final it's pretty obvious which I'm going to go with. Problem is, now, I'm starting to do a bit of freelance security consulting here and there, and I need to have a portable Kali partition with me. I also need to shrink the partition, but when I do I can never put it back into my main Windows partition so there really is no point.
Also, I'm running windows 8.0 right now, but I've had 8.1 before and the fixes still didn't work.

I connected a hard drive to my PC. I was able to read/write to it just fine. In fact, I've used it various times in the past. I just tried connecting it again now, and the drive is not showing up on Windows 8.1 at all. It's not being detected.
I connected the drive to a Mac to see if it was the drive, but it wasn't: the Mac was able to read it just fine.
I've had a similar situation in the past with this machine, where my iPhone was, seemingly out of nowhere, no longer recognized by the system. Plugging it in would register on the phone, but the PC wouldn't acknowledge its existence.
I'm completely at a loss as to why this can be. Other drives connect to the PC just fine (in fact, I have another one connected now, as I write this, backing up some data).

I have a USB hard drive which has two partitions:
1 x 100GB partition formatted as FAT32
1 x 900GB partition formatted as NTFS
(these sizes aren't perfectly correct, but it's a 1TB drive that's split in 1:9 proportions)
On my Windows 7 laptop, both partitions are visible in My Computer, and I can read/write with no problems. (On the same laptop, an Ubuntu install can also see and use them perfectly)
On my new Windows 8 laptop, the 100GB FAT32 patition appears under My Computer normally, but the 900GB NTFS partition does not. If I go to Computer -> Manage -> Disk Management, I can see the partition. It has no drive letter or file system listed, reports as "healthy, primary partition" and shows 100% free space. If I right click on the drive's entry in the list, my only options are "delete partition"; everything else is greyed out.
So, to summarise: One hard drive with two partitions. Both partitions work perfectly in Win 7 and Ubuntu. Win 8 can only see the FAT32 partition, and treats the NTFS partition as if it is junk.
way to persuade Windows 8 to mount this partition? I know that the drive and partition are fine, but for some reason Windows 8 isn't interested.

I've just built a new computer that has a 2nd hand HDD as the secondary drive. It was causing messages to appear like "Hard drive failure imminent - do you want to back up the drive". Since I was still setting up everything on the primary drive I disabled the messages by clicking "Do not show these messages again". Now I realise I should enable the message and remove the offending HDD. I'm running windows 8.1.
How do I re-enable these messages?

Over the last couple days, I built a new PC and installed windows 8.1. Initially I had some issues installing windows, so I unplugged all my drives except the SSD and DVD. I installed windows to my SSD.
Everything works great!
Now I started adding my drives back in 1 at a time. When I plugged my 2nd SSD in, it showed up in BIOS, but not in Disk Management or Device Manager. So I booted back into the install CD, it showed up in the disk manager there. Since this was also a blank SSD, I partitioned and formated the drive from the install CD, then exited the installer and booted back to my windows drive.
I have 2 SSD drives working great!
Now to add my 2TB HDD... Same issue, it shows up in BIOS and the install disc, but not in Disk Management or Device Manager. This drive does not have a boot partition on it, however, it does have two existing data partitions. They were made from my previous windows 7 system and the option to delete these partitions is grayed out in the install disc menu. I also have some data that I would like to keep on it. I have a USB dock that I can use to read the contents of the disk just fine. Everything is there and in working order.
What is different about Windows 8.1 that is preventing my hard drives from showing up in windows proper? I am reading things about UEFI online, but nothing seems to fit my exact scenario. I will try and post some screen shots when I get back at it.
System:
Mobo- Asrock Fatal1ty Killer z87
CPU- i3 4330
GPU- Gigabyte 660 OC
SSDs - Kingston V300 120GB
Windows 8.1 64bit

I have been experiencing problems trying to back up to external hard drive this week and keep getting an I/O Error with various error messages including 0x8007045D My Hard Drive is "G" and I can see it through my computer no problem and I also have my ITunes library on it and the ITunes music is working fine.
I am getting a message in Action Centre saying my Back Up did not complete successfully and then I have the option of Try to Run Again or change back up settings. If I select Try to Run again windows cannot find the disk or network location and if I change settings "G" does not appear. It seems Back Up has detected an error on my "G" which is preventing it from running the back up.
Also in Disk Management I am prompted to initialise a disc before logical disc manager can access it so I select MBR and I get I/O device error and disk 1/G is unknown/not initialised.I have tried powering the external drive off/on and also disconnecting it from the computer but no difference and at present I cannot save anything to the external hard drive. There is a previous back up already on the hard drive but this is not accessible at present.clearing this error so I can back up again without loosing what is stored on the hard drive in particular my ITunes library.

I recently purchased a WD 1TB external portable hard drive.When I first got it it was immediately recognised by my laptop (a 2 day old Asus Ultrabook S400C). This is my first time with Windows 8 so I am still learning to navigate it.
The first thing I did was transfer 650gb of movies and music across. I didn't format the hard drive first, maybe that was my first mistake. My files were still recognisable on my laptop and my WD TV Live media centre. The next day all of a sudden my media player wouldn't recognise it and when I plugged it back into my laptop it also cannot see it.
The device can be seen in device manager (when I click on properties it says it's working corectly), but not in the drives list in my computer. It is showing as "Disc 2" 'Not Iniitialised' and when I click on 'Initialise' and choose 'MBR' and hit OK it comes up with this error msg: 'The request could not be performed due to an I/O device error'.
