SOURCE: Data Recovery from Seagate Desktop Expansion 500GB External Hard

This is a solution I have used in the past and it has worked. It's a Seagate Recover utility for end users.

If the data is absolutley critical and very valuable, you can send it to Seagate and they are very good at recovery as well. It gets a little pricey at $800, but I too have had to use that as well for mission critical data I could not afford to lose.

SOURCE: Seagat 500GB Portable GO external HDD not recognised on PC

first of all you should try it on deferent pc , if its ok then that leads us to insufficient power provided through usb ports , try using back usb ports not the ON-front, and if the problem still try using dual-usb cable like thishttp://www.cooldrives.com/usb-power-cable-mini-b.html and if the external hdd doesn't work at all it might be the usb controller board inside the hdd cage needs to be changed if you cant find a similar one you may buy a new empty cage

If the drive is formatted with NTFS (the format used by recent Windows operating systems), then you won't be able to write to that file system.

What you will need to do is reformat the drive to HFS or FAT32.

If you will be moving the drive between a Windows and a Mac, then you'll have to format with FAT32. If you will only be using the drive on your Mac or other Macs, then format the drive with HFS.
NOTE: unless you copy the existing files off of the drive first, you will lose all data on the drive.
To do this, do the following:

• Copy all existing data off of the Seagate drive to a safe location
• Unmount the Seagate hard drive
• go to your Machintosh HD / Applications / Utilities folder and start "Disk Utilities"
• Select the Seagate drive from the list
• click on the Erase tab
• Select the Format. For HFS choose "Mac OS Extended (journaled)" for FAT32 choose "MS-DOS FAT"
• Type a name for your volume in the Name: field
• Click the "Erase..." button and allow the Disk Utilities program to format the drive
• Once the drive is formatted, you will be able to save files to the disk.
