I have an old HP Pavilion dv9000 series laptop that I've installed Ubuntu 12.04 on. The laptop is large enough to have two hard drive bays. One has one of the two original Samsung hard drives (it's the primary) and the other has a newer Western Digital Scorpio Blue hard drive. (Both are SATA II by the way.)

Before I installed Ubuntu, the Samsung drive had Windows Vista on it and I had formatted the WD drive in NTFS (it's blank right now). So when I first boot Ubuntu, it shows a 250 GB filesystem (the Western Digital drive) in my file browser. But if I click on the link, it gives me an error message saying it had a problem mounting the device.

Then if I close the file browser and reopen it, the link is gone. I've tried using GParted to find the device, but it doesn't know it's there either. The WD drive doesn't even show up in the list of drives. Is there anything else I can do to get Ubuntu to detect the device?

try the command

cat /proc/partitions

It will print a list of physical block devices reported by the kernel like usb memories and attached hard drives. If you cant find your disk there. You disk or secondary controller port is probably broken.

with the command

 dmesg |more

you might get some more information from the kernel regarding any potential problem.

If it does show up there under /proc/partitions, it sounds like it could be some filesystem that bugs out when you try to mount it. Since its empty create a filesystem on it

sudo mkfs.ext4 /dev/sdX

where X is the hard drive letter. Make sure to pick the CORRECT disk since this command will erase everything on that drive.

Says "/dev/sdb2 is apparently in use by the system; will not make a filesystem here!" on sudo mkfs.ext4 /dev/sdb2 –  enthusiasticgeek May 29 at 16:41
