2nd sata hard drive not recognized by Windows

 subhadeep -
I just installed a 2nd sata hd on my Dell Dimension E510. BIOS recognizes the new drive as does Device Manager. But Windows Explorer and my other software doesn't see it. If I click on My Computer, it's not there.

I using XP SP3. I have 1 DVD/RW, 1 80GB Primary Hard Drive, 1 Removable USB Hard Drive, printer, USB mouse etc. Nothing really fancy.

I've drive the uninstall/reinstall driver routine, check BIOS, killed my primary IDE DVD drive. Funny, I've got one piece of software (Paragon Backup/Restore) that detects the drive for reading but not for writing.

Any help would be appreciated.

Did you partition and format the drive after the install? It will not show in Explorer until you do.

If you have a CD of software that came with the drive - use it to partition and format.

If you got a bare drive then:
type diskmgmt.msc in your run command
You should see the drive in the graphical display on the right of the screen.
Right click the drive and a drop down menu should give you a choice to partition:
you should partition it as one big partition the full size of the drive.
Then go back and right click again and select format

after that (you might need to restart windows) you should see the drive in Explorer (My Computer)

Good Luck
Thank you
