Seagate GoFlex Desk Driver  

Hmmm... frustrating issue no doubt. What chipset and bios version are you running? Do you have the general storage controller drivers installed properly? Is there anything else showing up as problematic, or is this the only issue?

I was having the same problems with my GFH 1TB for over a year. I finally got it back up and running again......Or I should say I'm able to locate it now. So I'm able to use it. This is how I fixed the little SOB....lol
Something worth mentioning, This will flash your GFH resetting Admin Account, unless you use the same User Name and Password when you set it up, you won't have access to the files under that account. So if you forgot the sign up info you used to install it the first time...........The info is still there, just unable to access it.. In my case I didn't purchase MEMO, being my trial period ended I'm left using Seagate Share, which is also a trial.....LMFAO they should pay me for the trouble this thing has caused me..... But with out further ado......or something like that...lol heres the instructions. These are from Seagate Support under GFH Trouble Shooting.

These instructions will reflash your GoFlex Home to factory, requiring you to re-configure the device.
Steps:
Download the http://s3.amazonaws.com/downloads-ax...1_firmware.zip firmware ZIP file containing the GoFlex Home firmware.
Format a USB key with FAT32
Extract the Zipped files to the USB key at the root level. No other files should exist on the USB key.
Gracefully remove the USB key from the PC and insert into the GoFlex Home's USB connector.
Power off your GoFlex Home, ensure power cord and Ethernet are still connected.
Remove the hard disk from the GoFlex Home.
With your GoFlex Home powered off, press the Power button and hold the Reset pin. The green light will blink immediately, followed by the white light. Release the reset pin and wait for the device to complete booting and obtains a steady green light (approximately 3-4 minutes)
Your device should now be reflashed, remove the USB key and continue with Setup
To recover your data, simply re-create the previous user accounts.

My first attempt I saved this file to a USB Key then extracted, which won't work (I didn't understand what root level meant) As soon as I re formatted the USB Key again Fat32, downloaded the file to my Computer and Extracted it to the USB Key following the rest of the directions worked like a charm! Thanks to Kenji on another Forum for helping me...

Hope this works for you, it may have won a few battles but it didn't win the war! lol

Do what I did, take it out of its case make it an internal.

I had both a WD 1TB & and a 2TB Seagate, both are now internals.
