Cyclic Redundancy Check, Unmountable Boot Volume?
Jan 15, 2013
Alright so I've had my computer for right over a year. Never experienced any problems. However, yesterday my toddler got ahold of my laptop for 15 minutes, i came back and he had locked the desktop and several files were opened when i typed my password and got back in. The computer was running slow so I restarted, when I restarted it would not load. When i got home i decided to reformat the whole thing.The reformat went fine until it was over and the computer restarted. It kept going in a loop. I could see there was a blue screen but before i could read it, it would dismiss it and restart all over. So i disabled the computer from crashing and restarting after the error so I could read the blue screen. The blue screen read Unmountable boot Volume. I found my system repair disk and inserted it. The Bios is showing the HD, but when i try to access it from my command prompt in my startup repair, it says Cyclic redundancy check. I do not have the windows 7 installation disk and have always reformatted from the system repair. I'm starting to believe my HD is fried, but I found it a little difficult to believe since he was only alone with it for 15 minutes and the computer has never shown any signs of HD failure ever

Recently when I booted up my desktop, I get the error from Catalyst Control Center"No AMD driver found or the AMD driver is not functioning properly. Please install the appropriate driver for your hardware." (Not the actual text, it's what I remember)(Hence I'm stuck with the generic driver without support for widescreen resolutions)I went to Device Manager and selected my "ATI Radeon 4800 Series", then clicked 'Update Driver', but I get the following error:'Windows found driver software for your device but encountered an error while attempting to install itData error (cyclic redundancy check)'.I don't think it's the driver file's problem as I downloaded it fresh?I have no idea what's causing the error.. I don't think it's the video card's problem as it still shows up in my Device Manager, and I've tried System Restore, but I get the error that 'Windows is unable to replace C:Windows with the backup copy' or something similar.

I'm trying to copy a video file from a DVD cam disk that has been finalized but keep getting a CRC error. Is there any way I can retrieve the file and copy to my laptop hard drive? The video plays completely from the DVD. I have multiple DVD disks that we have videos taken from various times and I have not encountered this problem on others.

Ok, my computer had been having problems before but now when i'm booting up my computer I get the blue screen that's says unmountable_boot_volume right after the starting windows screen. I cannot get windows to start in safe mode or any of the other advanced boot options. The only time I don't get the blue scren is when I try start up repair, which just causes a black screen with the cursor. I googled the problem and from what I can gather I Need a windows 7 disk to repair this problem but my problem is I have no disk nor can I get a hold of one. Is there some other way to fix it without the disk?

find a way to repair the hard drive for my wife�s <one-year-old HP Pavilion dm1 laptop so we can recover her data� at this point in time the partition on the drive is inaccessible (to me at least).Here�s a brief rundown of the scenario. On Saturday morning my wife woke me up to tell me her laptop had blue-screened while she was working on an online document, and would no longer boot into Windows.When the system is powered-up it seems to be going through a normal start-up process� displaying the Windows 7 pulsing logo for a minute or so. Then is switches to a notice asking if the user wants to run start-up repair (recommended) or start Windows normally. If start-up repair is selected the system will eventually display the default Windows 7 desktop wallpaper, and the hard drive light will indicate activity for a couple of minutes�. There�s even a mouse pointer that can be moved around� but no dialogs, controls, or anything else will ever appear. We left it in this state for more than 30 minutes to make sure.
If �start Windows normally� is chosen the system will eventually blue-screen , with the error reported as �Unmountable Boot Volume�.I tried pulling the drive and dropping it into an external drive bay, but when I attempted to go into the main partition I received a notice that the drive needed to be formatted first (which I obviously didn�t do).I�ve also tried booting into a Windows 7 installation disk via an external USB drive (the laptop doesn�t have a built in optical drive), as well as booting into the same from a thumb drive. In each case I selected �Repair your computer� from the menu, only to get to the same scenario as before� with the default Windows 7 wallpaper displayed, but no sign of the System Recover Options tool/dialog� so I can�t even begin to try and repair the install.On the plus side, she finally seems to understand what I�ve been telling her for years� that she needs to regularly back-up her system. Unfortunately all her research and papers from her current studies at college are stuck on the drive� and we really need to get them back.

The laptop was running slow and I decided it was time to clean things up and get her running like new again. Backed up everything and wiped the drive using KillDisk.Three and a half hours later when the process was done I popped in my Wndows 7 OEM disc only to be greeted with the dreaded Unmountable Boot Volume on that pretty blue screen . Tried several times but it's the same thing each time.

I received an unmountable boot volume error when starting up my computer last night and came to the conclusion that my 120gb ssd which contained the windows installation has failed.I still have my 1tb hardrive however, if I buy another harddrive or another ssd, will my computer work normally if I install windows with my recovery disk on the new hdd or ssd? Also, is it as simple as placing the new drive in and then installing a copy of windows on it or do I have to do some other steps prior to that?

I was setting up a Win7 new build with an Asus P8B75-V and an SSD. Although I previously have done clean installs with UEFI motherboards and SSDs, this time the install DVD created a GPT volume on the boot disk (much to my surprise and which I discovered opnly after loading all the apps, moving the email, etc, etc.).
Knowing a lot more about basic MBR volumes (and how to fix problems), I would like to convert the GPT to a basic volume. I have Acronis DiskDIrector 11 which can convert the GPT to MBR, but when I tried that, it rendered the disk unbootable. (The conversion resulted in a 124MB unallocated space, followed by a 100MB FAT32 volume (!?!?!), and then the rest of the drive as NTFS.)
Is there a way to convert a boot disk from GPT to basic and have it be bootable? Is there anything that can be done with the converted HD to make it bootable?

So I am wiping my hard drive by booting with the Windows disk and going to command prompt. I successfully formatted drive C:, about 100 MB of system files and D:, about 500 GB or the bulk of my hard rive. These were the same hard drive, but separate partitions apparently. In Windows it just appears as C: altogether hiding the system files so you don't do something stupid. After I had cleared those two drives, I thought everything was gone until I remembered that it started me out in X:sources. I went back to it and was like what the heck is this? I went to the root directory, X: and typed dir for directory. There was an executable setup file, and four directories including the "sources" one, Program files, Windows, and Users. The whole drive was about 30,000,000 bytes which is I guess 30 MB. It's volume label was called "Boot". I tried to format it, and it said "Cannot format. This volume is write protected." What is this X: drive and is there a command to remove the write protection? Also, what would happen if I did eliminate this data? Could I still install Windows back from the DVD or would that not be possible without those them?

I have a 2 year old vaio that has i5 and 8 gb of ram. I have windows 7 professional x64. My computer froze while on the Internet, and when I manually shut it down and restarted it, it gave me two options. Start repair console, and start normally. When I started it normally, it froze on the windows logo. I restarted it, and tried recovery console, but it loads, then gives me an arrow with a background of blue and a bird on the right, which is windows 7's background when logging in. But it only shows this.I have tried safe mode, but that freezes on classpnp.sys and I have tried to boot from windows 7 recovery disk. I have also tried windows vista recovery disk. When the windows 7 disk booted, it loads and then asks for my country, but then again shows just a cursor.Blue screen of death error is unmountable boot volume.

I don't know if its a coincidence, but I left my blu-ray drive open when I turned my PC off, and all hell broke loose. Now I get these Unmounable Boot Volume. So Far,
- I've switched around the boot configuration. I've taken out the cmos battery.
- I've disconnected my 2nd hard drive
- I've reset bios default settings
- I've switched the SATA ports
I don't know what else to do, because I don't want to do a Fresh OS install. Right now I'm just working on 1 hard drive. my second 1tb is disconnected from power and data and I'm having the same problem. I also just disconnected my Blu-ray drive. And I did the start up repair. Niether worked.

So it all started last night. My computer was unresponsive, and after clicking "shut down" a few times to no avail, I decided to do a hard reset. I didn't think anything would happen, but afterwards it just wouldn't boot back up. It goes to the windows logo and stays there. I don't get any errors, it just hangs there. I have tried many things, so far nothing has worked.
I have tried booting into safe mode. This does not work, it gets stuck at classpnp.sys and stays there. I have tried booting from the windows 7 disc. This does not work, after it loads the disc it will hang at a black screen. I have tried switching from IDE to AHCI. This has worked, but not fixed the problem. When booting into safe mode it will crash instead of hanging.
When booting from the windows 7 disc I can almost reinstall windows, however I get the error "Windows could not format a partition on disk 1. The error occurred while preparing the partition selected for installation. Error code 0x80070057." When attempting to restore windows to a restore point I get the error "The system image restore failed. Error details: Windows backup failed to read from the recovery volume. (0x8078002F)"
I have tried connecting the SSD to a different windows 7 computer in a attempt to reformat it, however just plugging it in would give the same problem to that computer. So, is my SSD toast? Did I mess it up beyond repair? Now system repair will not hang on IDE, but still gives me the same errors. Also, now it says missing operating system. Not sure how that happened.
