whom i think youre seagate is on reading mode or not yet ready to use due to its still reading the data in the disk try the link below so you can follow there instructuions HDD External Hard Drive Corrupted and Unreadable Storage

Try new USB cable. Still no joy, data recovery is very expensive. Last ditch efforts (not all at once), try putting it in the freezer, twist the drive opposite corners, give the drive a firm bang

It sounds as though you have one of the following problems:

1. Dirty contacts that can be cleaned with CRC electronic component cleaner;
2. A faulty drive that may have been dropped at some point in time. Your drive may have a three-year warranty and Seagate will replace it. Just go online and provide the serial number; and.
3. You may have to reinstall the drivers. The Seagate website can provide this if needed.

1) Turn off your wireless router and unplug the external hard drive you want to make wireless.
2) Plug an Ethernet cable to the "Network-attached storage" device, and the other end of the cable to an available Ethernet port on your wireless router.
3) Connect one end of the USB cable to the wireless router's available USB port and the other end of the USB cable to your "External" hard drive.
4) Turn on the both the Wireless router and the External hard drive. Make sure that your Internet connection is still working.
5) Insert the installation CD and run it on your computer. Follow the installation instructions and install any utilities related to your external hard drive. There may be special utilities provided for flash drives that are not needed for hard drives.
6) Create a login name and security password for the "NAS" device during the setup process. When the installation process is completed, you will now be able to use your external hard drive.

Since this external hard drive is USB powered and felt on the floor, you could have a broken USB connector or interface card, both located inside hard disk case, you should contact Seagate technical support or repair service, or if you have electronics skills, you could open and check hardware by yourself.

Check if drive letter associated or a folder in MMC disk management

Seagate have agents around the world that can repair such.

Check the partition size in Disk Management (if running Win7 - download a free Partition Manager if not) and see if the system is seeing the partition correctly. Seagate has recovery software available on their website but you may just have to repartition and reformat.

Solution:
First, disconnect the power cable from the back of the external hard drive:
If the power supply LED continues to blink:

1. Connect the power supply to a different outlet (or instead of connecting to a power strip, connect directly to an outlet in the wall).
   
   
2. If the power supply continues to blink after changing outlets, this indicates that the power supply is defective and needs to be replaced.
   
   
3. If the power supply stays solid, then reconnect to the external hard drive and see if the drive spins.
