I have same problem with the USB cable. Sometimes it is recognized, but about 80% of the time it is not. A few times I get the "drive must be formatted" message (which is not true.. don't format, you will lose your data!)
In general, connection under Windows 7 is intermittent. I have not tested it with any other OS.

it may depend on the USB controller chipset that is installed on your pc.
Some chipsets are "faulty" and does not recognize correctly some USB peripherals.
Maybe a driver update for the chipset (if available) will solve your issue.
If you have the possibility, try to install an external USB hub or a PCI expansion card to connect the hard drive to. Give preference for cards/expansions that have NEC chipsets. (Not Ali, VIA or other minor brands!)

I got a new GoFlex 1T and used the Mac Utils to format / run the drive. I purchased a Firewire 800 eSata adaptor to achieve hightest possible transfer speeds and avoid USB. It originally worked fine during first format and copies etc on my work iMac Firewire 800 port. But now, everytime i plug it in, the lights flash very quickly, and do not stay on. The drive does not mount. DiskUtility sees the drive as connected but cannot mount. Changing to the standard USB adaptor allows the drive to mount / function normally. Seagate utility says drive is fine.
On my Home iMac, i plug it in as the second drive in a FW 800 chain and my seagate mounts fine. But the adaptor and drive get very very very hot after some time, despite no disk activity. Again, USB adaptor is fine.
I expect there is something wrong with the adaptor electrical specification. A FireWire 800 portmay provide more power than a standard USB 2.0 port, and the adaptor seems 'overcharged' thus overheating / causing inability to mount directly to the computer port. When connected as the last drive in a Firewire 800 chain, it may be pulling less power, allowing it to function, but still too much so that it heats up.
Please look into this. Im not going to use the 800 adaptor (was expensive) till i know more. Im sure the heat will fry the drive eventually.

I'd just like to add my name to the list of disgruntled users having no luck at all with the goflex esata adapter.
i got it because i have esata on a laptop, 3 desktops & a nas and had intended to use it with the new 1tb freeagent goflex portable drive i just bought and it doesn't work with ANY of them (two have powered esata ports, it turns out the others do not).
how hard would it have been for seagate to have put an extra mini USB slot for a cable to provide additional power for the drive?
also, whats with miniUSB? this is supposed to be 2011 and everything i have now is microUSB and has been for over a year, so why are we travelling back in time for what is supposed to be a cutting edge drive?
this esata adapter is clearly not fit for purpose and should be replaced by seagate with a new model with a usb port for extra power.

Everyone who mentioned their problems with the esata cable refered to the 1TB drive. I have a 500 GB pro model and it works fine connected via my laptops powered esata port using seagate esata cable. Either the more capacious drive is more popular or these problems manifest only in it. Is it possible that the esata cable does not provide enough power for the chunky 1 TB model? Is there anyone experiencing esata problems with smaller drives?

bonjour i am french !
j'ecris en francais !
j'ai acheté ce disc dur seagate goflex , moi aussi j'ai le meme probleme que vous .
l'adaptateur esata dur disc dur qui s'achete en option ne fonctionne pas car il a besoin d'une prise "power over esata" ce qui signifie qu'il a besoin d'une source electrique pour fonctionner , hors l'esata ne fournit pas de courant electrique.
je suis tombé ici sur ce site en tapant "probleme esata seagate goflex" et je m'appercoit que finalement je ne suis pas le seul a etre dans ce cas .
j'ai une solution a ce probleme d'alimentation je vous donne le lien , mais je ne sait pas si cela fonctionnera avec le disc dur seagate goflex ,
lien vers l'adaptateur --> [url]http://www.connectland.eu/products/fiche/id/155/na
on peut le commander a cette adresse internet au prix de 50 euro (waou il reviens cher ce disc dur)
je le prends et je verrais bien ensuite si cela fonctionne et je vous mettraient au parfum sur le bon fonctionnement de ce bidouillage.

Désolé pour l'inconvénient, mais merci pour l'information.

Forgive my English
I just want to add my 2 pennies to the lot... I have come across the same problem. I though this was an isolated instance, so I tough of tracing the pin outs of the cable and measuring the power. But I have 2 powered esata ports, why would both fail to work. But again. All hdd'sare designed to take a certain amount of power 2.5" Hdd are not allowed to draw more tha 500mA therfore 120Gb,250Gb,320Gb,500Gb,1Tb etc would use the same maximum current alowed. The bigger capacity drives do not use more power. There is no such thing as over powering, unless you fail to use the 5V and use teh 12V instead then you will burn the drive. That is why they make things idiot proof.
To get back to my point. the interface cable is quite simple. its has a few requirements to get it to work.
2. DATA Inteface
12V is normally used to power the drive(not used in this case)
5V is used for DATA and this case to power the drive aswel.
2 Data interface
5V used for the interface signals
To protect data transmissions from external interference and the drives.
Esata is one SATA port with power to connect ot external drives, therefore it must work. The power comes from the motherboard or if you dont have onboard esata from the power supply, and a SATA port on the motherboard is used for the interface. It should be a direct link. In theory you should be able to trace each pin, but there could be protective electronics inside that may prohibit such an effort.
I do not want to enrage people but the cable should be straight forward. no silly electronics. When you plug in your esata drive, the light should come on( not in my case I think its faulty). Then in your windows device manager you should scan for hardware changes, that should do the trick if not return the cable. Linux users I just use my disk utility if it does not show its not connected.
Thanks for reading..

... so apparently I'm one of the lucky ones
Like others the USB 2.0 adapter/cable works fine ... but for a 1TB external drive, that's not fast enough. So I spend the extra money on the eSATA adapter/cable.
Win 7 recognizes the drive fine, but Seagate Manager software does not recognize the 1TB drive via the eSATA cable.
I've used Seagate Manager successfully for at least a year with an older 320 GB Freeagent Go drive, and SMgr recognizes the 1TB drive on the USB 2.0 cable.
Can anyone confirm whether SMgr should be able to backup to a 1TB eSATA GoFlex ultraportable?
Makes no sense that it doesn't

How do I know whether my eSATA drivers are up-to-date?
I can only confirm that hardware vendor doesn't offer any updates.
Dev. Mgr. shows a "Seagate FreeAgent GoFlex" disk drive with Microsoft driver 6/21/2006 v. 6.1.76000.16385 and Win 7 policies:
Removal: "better performace (default)" to enable write caching
Write-cache: "Enable write caching"
Is there anything to change, that will make Seagate Manager see my new 1TB Seagate GoFlex with upgrade eSATA cable?
How is it possible that Seagate can only offer only dead silence on this Seagate Manager failure to recognize my new backup device?!
