Repairing Disk Errors

[Seyi2]

My computer was turned on and "Repairing disk errors. This might take an hour to complete" was on the screen. Once this completed I found that all the files were lost. I did a fast check on the hardware but everything passed. The fast test PASS ID  is as follows: 29997-53110-53654.

The serial number:[personal info removed]

Will I be able to recover my files from the computer?

No one knows for sure. Why? Because when CHKDSK encounters a corrupted sector, it takes that out of use -- meaning the data formerly in that sector is gone.  Data recovery apps MIGHT be able to get that back, but there is no guarantee.

The best approach to doing data recovery from a drive is to remove it from the existing PC and connect it another one using an adapter, but since this is an All-in-One, which basically is an oversized laptop, that can be very difficult to remove.  So, your only alternative is going to be to try to recover the files in-place to external media, and I don't know if that will work.

You need to do the following:
1) Download and install this utility on the PC http://www.majorgeeks.com/news/story/recover_data_in_3_steps_with_minitool_power_data_recovery_free_...
2) Run the data recovery utility to see what can be retrieved from the drive.

If that tool does not find what you need, an alternative is Recuva http://www.piriform.com/recuva

And, if that does not work well, the best tool out there is this one, but only the demo version is free https://www.runtime.org/data-recovery-software.htm
