Hard disk drive is not showing - Seagate (ST3320820U2-RK) 320 GB USB 2.0 Hard Drive

Right-Click "Computer", Manage, Storage/Disk Management. What you see here is what you have, or at least what Windows thinks is connected. If you have a missing hard drive, check your hard drive connections.

The only thing that I can think of is that you need to go into computer management and click on the "disk management" sub-heading under storage. From there all of the hard drives in the computer should show up. Find the new hard drive in the list and right click on the part where is say Disk 1 or Disk 2 or which ever disk is the correct one (it should be around 930gb or so). Then select initialize disk, and follow the wizard through the choices to setup the disk as a basic hard drive. After the disk is initialized you need to format it and then you should be access the drive in my computer.

Hello Ravindr,

After connecting the Segate Hard Drive in your computer go to Control Panel. In Control Panel you will the option Administrative Tool. In Administrative Tool open the Computer Management and you will find the number of attached Hard Drive and the Partitions they have. If the Hard Drive you have attached is not showing the partition then there may some physical damage with the Hard Drive media. Please get your Hard Drive checked by Segate professionals and then replace the Hard Drive with new one.

you need to format that unalocated hard disk
at windows, go to computer management>disk management
at there the all drive of hard disk will show, then right click at unalocated disk and chose format, your hard disk will show as active hard drive, from there you can shrink your disk to 2 partition

It is possible that the power cord, data cable or pin selector jumper has been dislodged.

Go in to the bios and try to see if the drive can be recognized.

an outside option is that you contracted a virus that destroyed the MBR (Master Boot Record) rendering the drive unrecognizable.

diagnose top to bottom.

It's possible that your computer's motherboard is "old", and it only supports a maximum of 32GB per disk-drive.

Buy a new 80GB or 160GB disk-drive, and copy all your files from the "old" disk to the "new" disk.

Are the Hard drives setup as master & slave ? (plastic jumper on Hard drive at cable)..... is the Hard drives connected on separate ide cables... if they are ide drives ?

Is it formatted ? Does it have a drive letter associated to it? If not then either format it (right click on My computer -> click Manage -> click Disk Management. Now right click the drive if it is showing there and either create partitions and/or format it if it not already formatted.

If it's already formatted, and you just need to assign a drive letter, then in Disk Management, right click the drive and click Change Drive Letter and Paths and assign an unused drive letter, say Z.

Close Computer Management and open My Computer. The new drive should show up now.

HTH,
