Windows 7: Unable to Boot from Hard Drive I/O Error and Error 0xc000000f

If PW is detecting the HD, then no problem. But sometimes boot disks will pretend to be running a function (like Disk Check from the Win7 disk) and are just spinning their wheels with an actually undetected HD.

Ok, well so far all the PW has discovered is a lost/deleted System Reserve partition thats only 100MB, but it still at 0%, how long should this thing take?, and thats good to know, thanks

On PC #1:

If you reinstall Windows now, all the data in it will be overwritten and you will lose all that data. So reinsatall only after data recovery attempt.

Yes, try the Partition Wizard as detailed in my previous post on your PC #1.

Let us see where it takes us.

If we can bring it back to the condition as it was prior to the diskpart clean, we can assess and see what best can be done.

( Running diskpart clean wipes the first 2048 sectors including the first sector which contains the MBR code and partition table.It does not delete the Partition Boot Record - which is the first sector of each partition and any data in that partition. Writing the MBR code and then the partition table if PW finds the partition/s should bring it back to the original condition. Then it should be possible to recover the data hopefully - provided your HDD has not deteriorated due to creation of bad sectors)

So the PW didnt show anything except 1 System Reserve Parition (100MB) and then 4 identical Boot PArtitions that are each 3.01 MB, I double clicked all of them so see the contents and nothing.

So i guess now i will attempt gregrockers solution once more and wait on any other ideas

Also at the bottom of the PW wizard it says,

"If MiniTool Partition Wizad can't find your lost partition, dedicated data recovery software is required to restore your data. Please try Power Data Recovery free from www.PowerDataRecovery.com"

any experience with this?

edit:
OK, so i think the drive is detected by my BIOS because when i try to boot from it, it asks me to insert boot media and i no longer get the I/o error like previous and i dont get the 0xc000000f drive inaccessible error, so do i still attempt to run the makers diagnostic and the check disk scan? I will wait for a reply before proceeding.

edit:
I also have a semi unrelated question: A while ago ( i think i mentioned it in an earlier post but anyway) I maybe corrupted my roommates old harddrive but there was nothing important on it ( it was getting an I/o error as well) so i just bought him a brand new one. Anyways, I tried to use diskpart to clean that hard drive and when i got to the 'create partition primary' it was unable to write it because of an I/o error, BUT previously i had tried to use DBAN to format the hard drive but it was never detected by DBAN so i could not. NOW however DBAN did detect the hard drive and i was able to select it for formatting (which is currently on pass 2/3 at 30% no errors). Do you guys think i will be able to use it again?

I am back at my desk after a night's sleep.

Yes go with greg's suggestion and check whether anything clicks and post the results.

By the by I just want to confirm whether you did the Rebuild MBR in PW as suggested.

Did PW Quick Scan complete? How much time did it take? ( Just for information)

If following greg's suggestion of " Copy/ paste" does not yield the expected results, then go back to Partition Wizard and run a " Full Scan" which is equivalent to the Deep Scan in Test Disk. This deep scan will take a lot of time. So be patient.( Provided Quick Scan completed, I see no reason why the full scan also will not complete.)

All DIY data recovery is a time consuming affair with no guarantee whatsoever, except in simple cases. That is why prevention - backup - is better than cure.

Well good morning , The quick scan took pretty long i think around 2 hours? maybe... i wasnt really looking at the clock, and yes i rebuilt the MBR which is why i think its asking me for boot media instead of giving me an error, and thanks for the reply ill get right on it.

Rebuild MBR almost always requires Startup Repair - Run 3 Separate Times,
after you confirm that the System Reserved (if you have it) or C must be Partition Marked Active

Ok, So i used PW option to rebuild MBR then ran a scan, which showed the 1 system reserved and the 4 boot partitions, I didnt think or see that they had my data so i exited PW and took out the disk and now i am trying to follow your suggestion here:

Once detected try again rescuiing your data, then run the maker's HD Diagnostic extended CD scan, followed by a full Disk Check.
So what is this about the System Reserved Partition? Is that something i should start working with/on? Do i go back to the PW?

Also referring back to the Hd Diagnostic scan, I went through the links you provided and ive gotten to here:
WD Support / Downloads / SATA & SAS / WD Blue / SE / SE16 (SATA II)
and
http://support.wdc.com/product/downl...sid=30&lang=en

which of the links inside those do i download and burn to a CD/Dvd?

Stick with jumanji's guidance since he is here now. I was only adding that if you were running Rebuild MBR to try to start unbootable Win7 then it almost always requires running Startup Repairs afterwards and doesn't usually work on its own. Also one should always confirm the Active partition before doing Startup Repairs as Win7 will also not repair no matter what you do if the correct partition is not marked Active, usually System Reserved or (if you don't have it) C. You can confirm this in PW.

I'm still trying to recover data I used the diskpart clean command on. The only partitions that showed up in the PW wizard were the system reserved partition and 4 Boot partitions. Im wondering where to go from here. Main focus is still to recover the lost data.
