My Daughter has a Samsung NP A720 laptop and recently it's been causing problems.
Twice now it's gone into BSOD with Unmountable-boot-volume Stop: 0x000000ED (0x86D5D3D8, OXC00000185, 0X00000000, 0XOOOOOOOO)
The first time it happened it took over 48 hours for the systym to recover now it's gone again, this time I was lucky and got it running again within a couple of hours.
This is driving my daughter (and me) nuts.
I can't do a backup as it tells me there are bad sectors in the HD and to replace it, to do that would mean a new drive and Windows 7 disk (neither of which she can afford) the laptop came pre-installed with no disks.
If anyone has an idea on what the problem is and how to fix it I will gladly give it a try.
Thank you

If there are bad sectors on the hard drive all you can do is replace the drive. There is no other real solution, unfortunately.
The Windows 7 disk isn't a problem if you know somebody else with a Windows 7 disk, providing the licence on the laptop and disk types match, the disk itself doesn't really matter.

How old is the laptop?

A possible solution to our problem is cloning all the actual hdd and restoring to the new. With this you have the same disk structure and with no bad sectors.
I recomend you tou download and use clonezilla, it's freeware and very easy to use.

Thanks guys for the help, I kinda thought it would be a new drive but wanted a second opinion first.
I have Win 7 so will use that with her key ( Never thought of that )
Off to get her new Drive.
Thanks again.
