Windows 7: External Hard Drive Not Detecting. Disk 1 Unknown.

There was no need to have run the Full scan. Anyway no harm.

The basic principle here is you should select only those partitions that will make the preview map show your drive as it existed before.

Here you have selected the right partition, the first one and the preview map shows your drive full without any unallocated space. Do not select the other three which show as overlapped.

You had only single volume. Right. And your drive capacity is 250 GB right.

Now highlight the selected ticked partition in that screen and double click on it. That should show all the files in your drive. ( I think you had done it even in the first post and seen it. I could see it there) If you are happy that all your files are there close that Window showing the files and click on finish.

Anyway I repeat select only that partition that shows as existing and click on Finish.

Post the screenshot of the main screen.

Ok. I selected the first parition only and pressed Finish. This is what the main screen looks like

To start with did Partition Wizard show your external drive?

You are only running PRW on your system drive. All along I have been assuming that you are running Partition Recovery Wizard on your external drive.

Now it looks like PW is not at all showing your external drive.

So may be we have to start afresh.

Post a screenshot of Windows Disk Management with your external drive connected.

Also run Partition Wizard and post a screenshot. Does it show the external drive at all?

Not a good day for me to have duped myself like this.

How can I tell if Partition Wizard shows my external drive. All this time I thought it was running my drive.

Never mind. Things like this do happen.

We are back to your post # 3 and 4.

You tried to initialise the disk. Response : incorrect function.

You tried again. Response: "the drive cannot find the sector requested"

Partition Wizard cannot find the drive.

There are only two things I can suggest now.

1. Try your external drive on another working PC. How does it behave?

2. Run the manufacturer's diagnostic/repair utility and check whether the drive is OK.

Ok.1) I'll try with another PC tomorrow 2) I ran the sea tools and it failed the short generic test but passed the Drive self-test.

If your drive is a Seagate drive and you are using SeaTools for Windows, if the Short Generic Test failed, you have to run the Long Generic test with repair option to fix any bad sectors.

Please read the user guide here http://www.seagate.com/files/www-con...dows-en-us.pdf

Find whether your drive is repaired or recommended for RMA./ warranty replacement. Save the log file/s for expert analysis if need be.

When you try the drive on another PC, try to get the screenshot of Windows Disk Management with the drive connected. If it shows up as unknown and not initialised then try to initialise and post the results.

If initialisation succeeds you will get a screen asking you whether you want to format the drive as an MBR Disk or GPT disk. Just cancel it and quit. Do not format.
