Cannot boot from HDDs after Power Outage

Alright, here is an update of my status so far. Thanks in advance Gregrocker for all the steps that are definitely helping.

Yeah X: is the cd dvd that I'm booting off of.. don't know why it's so weird.

-I downloaded a repair cd, minitool partition wizard, and WD Data Lifeguard. I put them all on separate CDs.
-I unplugged my Seagate drive.
-Put in the repair CD and it booted from it. I typed in those exe commands and they didn't seem to work.
-Then I went to startup repair, and restarted my PC.
-Windows booted from the drive, though it couldn't finished booting. I got a BSOD. Stop: 0x0000007B , which is expected.
-Booted from CD again and started start up repair. It took awhile repairing. It failed to repair the drive automatically. checked the repair diag.
"Root cause: A recent driver or upgrade may be preventing the system from starting."

This may make a little sense. The same night of the power surge I fixed my computer from a NOT LESS OR EQUAL BSOD by updating my drivers.

-turned my computer off and back on
-It booted normally (wasn't paying attention). Got the same BSOD.
So I figured the driver must be recognized by now.
-Booted from repair CD and it recognized the drive. I clicked next. It automatically did startup repair again. It couldn't fix it again. Same root cause. Error code 0x490
-I went to the cmd prompt and did a chkdsk c: /F /R
-Now I am waiting as it is taking a REALLY long time on stage 4... going through each of the files slowly. So I guess this means the data didn't vanish.
I will update on what happens.

Did Startup Repair ask you if it could System Restore? If not try running System Restore from the Recovery Tools list just below Startup Repair to roll back the driver.

Try booting into Safe Mode to uninstall the driver.

I would also continue trying to repair the HD using WD diagnostics/repair Extended scan.

You still have a HD, it would seem.

I'm not sure if it asked about System restore. However, I don't have any system restore points. That's another whole issue. I try to activate system restore but it never would let me, even when I was an admin. But that is unrelated.

I remember booting into safe mode the first time and I BSODed.. but when the chkdsk finishes I will try again. It is taking awhile.

But yeah, I was still thinking about using the WD repair tool and see if that'd fix it.

I'm still unsure what driver would cause the issue though. I don't remember installing drivers for any HDDs. The only driver I updating I think it somewhat relevant (and I think was the problem of my early BSOD) was something like JMicron Raid Tool. I updated it and got rid of it from startup (The BSOD occured on startup).

If you uninstalled your RAID driver or it failed during update, then that might be your problem.

Can you reinstall it at the load drivers link on Repair CD?

Did you have a RAID setup, or did your SATA use a RAID driver as some do?

What were you doing exactly with the RAID driver?

I don't know.. I don't do anything with RAID or w/e... I literally had no idea what the thing even was. It was just starting up on startup without me even knowing. I got rid of it from startup and nothing changed. I don't know what it does.

I think Startup Repair can't fix the problem because you have no restore points to reverse the failed driver update.

Some Gigabyte boards use JMicron RAID drivers in place of Intel, so it you uninstalled it or tried a failed update it might have messed up your SATA controller which would explain why you can't see your HD or data. However the driver should be in the Win7 driverstore as are all modern SATA drivers. You could find the exact driver for your SATA controller on the Gigabyte webpage for your mobo model, unzip it to flash or CD and insert it at the drivers link to be sure.

The other course would be to continue trying to repair the HD using Data Lifeguard extended scan and Disk Check. It might fix your HD, or at least enable you to copy out your data via the drivers link or using Paragon Rescue disk, which can also attempt to rescue your Win7 partition.

Others may have better ideas, but based on the bluescreen which you attempted to fix earlier, System Restore never working resulting in the apparent bad driver being unfixable now, and your other complaints I think you may be due for a new HD or at least a fresh clean install.

Here are some tips for getting the best possible reinstall based on hundreds done here: re-install windows 7

When you say that it makes me believe that the issue does reside with that specific driver. It logically makes sense. I am going to look for drivers for it.

Chkdsk found one smalll 4kb issue, but it didn't solve the problem.

I am currently running the data lifeguard scan, it is almost finished. Quick scan found 1 issue. I'll learn further once it finished. Thanks for all the help man. You know your stuff.

Alright for my mobo it has 2 options for SATA drivers... which is better?
GIGABYTE - Motherboard - Socket 775 - GA-EP45-UD3R (rev. 1.0)
Maybe the Intel one? How would I mount an .exe to a cd? Or can I put it on a flash drive and find it in the drivers section?

Alright, after the WD data lifeguard finished it found some issues and solved them but didn't solve the main issue. I'm still getting the BSOD 0x7B. So I will try to figure out the driver issue. If I cannot, would a repair install of windows 7 do things right?

Unfortunately you must be able to boot Win7 to run a Repair Install which is an in-place Upgrade done from the desktop.

If you can't get WinRe to recognize the installation for repair by inserting your chipset SATA controller driver, then see if the files show now to copy out your files. If not, you can try moving the HD to another computer to see if it's readable from that OS or using Repair CD.
