How can I 'see' a second SATA?

Clarifications

Have look in "disk management" and see if the drive is located in there. Or go to "add new hardware", and see if this brings up the drive. But what you do need is this:

This will check you disk and see if it is possible to get your info off it.

Please post back if you have anymore problems or questions.

Fist thing to check is whether the Drive is detected in BIOS.

If it isn't being detected it has most likely failed.

If it is detected you will have to Partition it so windows can see it. Make sure that it is on the second Sata port.

You need to look in Drive Management to see if it appears there. If it does the most likely thing is that the Partition Tables have been corrupted and you need to format the drive.

If you need to recover Data off the old Drive you need some form of Data Recovery Software. If you just want to use the drive Format it and use away to your hearts content.

If you need to recover Data off the drive there are quire a few different Data Recovery Programs available and you need to chose one of these before you do anything to the HDD. When you have chosen your preferred Data Recovery Program follow the Instructions to recover the DATA of the now invisible drive . Some will require you to Format the Drive and then run a Recovery and others will rebuild th Partition Tables so it's important that you don't do anything now that could destroy your chance of recovering data latter.

There are a whole lot of different programs available
Here is a short list of the better ones

While the last 2 are from the same company they are very different products. Win Hex should only be considered foe use by someone who knows Hex Inside Out while Davory is a great cheap General Purpose Application.

Personally I prefer the On Track Option but it's anything but cheap. However because I use this type of software a lot it's paid for itself many times over by now, for a cheaper option Spin Rite from Gibson Research or Stella have both very good reputations by other TR members.
