HELP! Unmountable_boot_volume - BAD SECTOR COUNT
Posted: 11 Aug 2012, 02:35
Help! My computer won't boot!
Windows says my boot volume is unmountable.
TestDisk says my hard drive partition has a BAD SECTOR COUNT.
I managed to salvage the files but can't rescue the disk.
What is it I'm not getting here? Help me out please!
Here are some details:
I own a Toshiba Satellite A10 laptop computer running Windows XP with an internal 40 Gb hard drive.
Printed on the drive is the following info:
Travelstar, hgst.com, Cyls 16383 Heads 16 Sects 63
Lately when I boot I see the Windows logo, and then a blue screen saying
UNMOUNTABLE_BOOT_VOLUME
and
*** STOP 0x000000ED (0x86385E30, 0xC0000015, 0x00000000, 0x00000000).
I made sure the hard drive was well connected.
I looked into my CMOS Setup and found nothing.
I tried booting from the Windows CD and running a few DOS commands:
chkdsk/r says the volume contains errors,
fixboot and fixmbr say the boot sector is damaged, and
fdisk/mbr didn't work.
I downloaded and ran utilities found on the HD's manufacturer's web site.
Nothing changed.
I finaly created a Ultimate Boot CD v5.1.1 containing TestDisk v6.2.
TestDisk sees the drive
> Disk /dev/sda - 40 GB / 37 GiB - ATA IC25N040ATMR04-0.
and it sees the Intel/PC partition
> Disk /dev/sda - 40 GB / 37 GiB - CHS 4864 255 63
When I chose [Analyse] it says:
Current partition structure:
Partition Start End Size in sectors
1 * HPFS - NTFS 0 1 1 4863 254 63 78140097 [S3A1377D003]
Bad sector count
The I chose [QuickSearch] and it says:
Disk /dev/sda - 40 GB / 37 GiB - CHS 4864 255 63 (en noir sur vert)
Partition Start End Size in sectors
>* HPFS - NTFS 0 1 1 4863 254 63 78140097 [S3A1377D003]
Structure: Ok. ...
At this point I can list the files and copy them to a USB drive.
Great! Thanks TestDisk and merci beaucoup Christophe Grenier!
But can I bring the HD back to life?
I tried to copy the backup boot sector over and rebooted,
I tried to rebuild the boot sector and rebooted,
I tried to repair the MFT and rebooted,
I tried writing TestDisk MBR code to the first sector and rebooted,
nothing worked.
I tried posting on the french section of this forum two weeks ago but got no answer.
I'm lost. Why does TestDisk say my partition has a BAD SECTOR COUNT?
What can I do to save this hard drive?
Please, somebody help me!
