Something totally wierd and shocking happened with my machine running on Windows 7 today (25-06-10).
This is what happened, everything was working fine till the evening. I was back home from a hard day, started my machine and i saw a message that windows has updates that needs to be downloaded. I check the required updates, there were couple of .net framework and few windows kb series. i assumed them to be normal critical updates and as usual i updated my windows 7.
After successful update windows rebooted and something weird happened. i have 4 drives, 1 primary C: and 3 logical (D,E,F). All of a sudden drives D,E,F were unaccessible. It gave Data Error: Cyclic redundancy <<something>> . And when i tried to right-click and open it, it asked me to format the drive. i thought it could have been something with the update. So i restored backed to my restore point created before the update. After restore the drives were still unaccessible, except the C: i was able to access the C:
I started disk management to see the state of the drives. Surprisingly all the 3 drives showed RAW healthy state. I was shocked as i had all my critical data in those drives. i tried running chkdsk from command prompt on these drives, but it gave the same error.
I then tried putting in the startup disk to boot from cd and check if my data was still there, i rebooted by booting from the startup disk. The screen freezed on a black screen. i removed the cd and rebooted my machine. This time it gave me an options stating start windows normally or repair. I tried to start windows normally, but it failed and just rebooted again. This continued several times. I then went on the option to repair. The repair process just stucked on attempting repair. I rebooted and tried to install windows again. But it said windows cannot be installed on the drive and showed me an unsed 239 GB drive which is my HDD (250GB). Where did my logical drives and the data in it go
i tried the following options from recovery disk i.e running the following commands from the prompt.:
BOOTREC /FIXMBR
BOOTREC /FIXBOOT
BOOTREC /REBUILDBCD
BOOTREC /SCANOS
but all the commands gave a same error "A device attached to the system is not functioning"
i just dont know what to do now ?? All my 12 years career data is in that drive !!
To add to the pain, my external backup drive has been sent to the vendor for RMA, since it had accidentally fallen from my hand and drive was thus unaccessible.
Please help me start my system and retrieve my data
