Hi all,

Upon doing a fresh install of Windows I've just managed to format the wrong hard drive.

I'm hoping that I can recover at least some of the data; it was a quick format/deletion as part of the windows install process rather than a deep format. I've had a search of the forums and have found some useful advice in terms of suitable programs to use to try and recover the data, and my impression from previous posts is that there's a good chance I can recover stuff.

The problem that I am having is that Windows cannot actually see the formatted hard drive. It doesn't show in explorer, RecoverIt or Recuva. It does show up in the Device Manager correctly as a 1TB Seagate Barracuda ST1000DM003.

How should I proceed to try and recover the data? I don't want to stumble semi-blindly and cause further damage.

Many thanks for any help that can be provided.
Tim

Did you download Recuva to another disc? Downloading to problem disc could be wrong. As you noted, don't do anything with the bad disc as further overwriting will occur. Hopefully someone who has used Recuva many times will post exactly what steps you should take including finding the missing disc, possibly changing bios.

I've downloaded everything to the main hard drive.

For clarity - I have two hard drives, one of which I install Windows & programs to, and one which I use for all of my personal files as a large filestore. I formatted and removed partitions of both, fresh installed Windows on the first (and now have the recovery programs on), but I cannot 'see' the second I guess due to the format/partition deletion.

I've just downloaded EaseUS partition Master (trial edition) and can see the second hard drive, so presumably I could try and recover the partition, but I don't know if that will screw up the recovery at all.

In the past I've used MBRWork (https://www.terabyteunlimited.com/do...e-software.htm) for this:

Quote:
MBRWork - Freeware utility to perform some common and uncommon MBR
and disk functions. Provided As-Is.

It can perform the following:

1 - Backup the first track on a hard drive.

2 - Restore the backup file.

3 - Reset the EMBR area to all zeros.

4 - Reset the MBR are to all zeros.

5 - Install standard MBR Code

6 - Set a partition active (avail on the command line too)

7 - Work with multiple hard drives.

8 - Remove EZ-Drive (You must boot directly to a diskette (by passing ez-drive)
for this option to show)

9 - Edit MBR partition entry values.

A - If no partitions exist in the MBR and no EMBR exists then this option
will allow you to recover lost FAT, HPFS, NTFS, and Extended partitions.

C - Capture up to 64 disk sectors to a file.

R - Restore up to 64 disk sectors from a file. This feature should only
be used by those who completely understand what they are doing!

T - Transfer/Copy sectors from disk to disk. This feature should only
be used by those who completely understand what they are doing!

P - Compare sectors.
I'm pretty sure it's also still built into some recovery CDs/software like TestDisk: https://www.cgsecurity.org/wiki/TestDisk

I used TestDisk in the end. It was slow but very successful

Yeah, TestDisk is awesome. I've used it to recover whole partitions with lots of success.
