VMWARE ESXI 4.1 - WINDOWS 2008 R2 UNMOUNTABLE_BOOT_VOLUME BLUE SCREEN

Hello,
I'm having a "UNMOUNTABLE_BOOT_VOLUME" BLUE SCREEN error on my VM, no recovery working while using install cd.
The VM has 3 disks of 256 Go, the second one has ntfs errors, I cannot run a chkdsk on it, the first disk (OS) seems to be OK (while using gparted) but cannot boot

Any help will be appreciated

have you tried connecting the virtual disks to another Windows helper VM to check files, folders and data.

but before running chkdsk, make sure you have full backups not vmware snapshots.

HI, yes I tried :
- the second disk cannot be accessed, browser or any thing else
, no I have no full backup, some error is fired when I try to make a copy, even in SSH (cp : read error ... )

okay, it looks like your underlying datastore is having issues.check RAID controller for RAID failure, or local host disks for failure.

your vmdks are corrupted because of hardware storage failure.

That's what I was thinking, actually they are local SATA disks, and I have no clue of how to check that on esxi.

I fired a "dosfsck" command, I'm waiting to see the results

check the VMware logs, but if they are SATA individual disks, a disk is failing with errors.

login to ESXi console or SSH, /var/log for logs

Also make sure you have the right disk booting, sometimes they get out of order, make sure bootable is scsi(0:0)

hard drive needs replacing.

the virtual disk are probably corrupted because they cannot be read.

Too bad !!!

Thanks, is there a way to force copy ignoring read errors so as to recover a part of the data from the vmdk files?

I'm about to try "Ddrescue" embeded in a rescue disk : http://www.gnu.org/software/ddrescue/manual/ddrescue_manual.html#Invoking-Ddrescue to copy data in a mounted vmdk stored in a separate disk (datastore) to the VM I need to recover

I would run a disk checker from the manufacturer to recertify the drive.

or use an imaging tool with ignore bad sectors flag.

Hello,
I finally succeeded to rescue main data, with :

1 - using an imaging tool with ignore bad sectors flag, but on the virtual images : "Ddrescue" embeded in a rescue disk

2 - mounting the virtual disk as slave on another virtual server.

thanks for all your helps.
