Seagate Freeagent Go Flex 1 TB Portable Not working

right click on the drive, properties, tools, format

This may be a power issue, the usb cable may not be supplying the disk with enough power. I have seen this many times but usually with external drives that use mini usb cables, and also with early model WD Passport drives. Possibly even a low powered usb port, if its a laptop or if connecting to a non-powered usb hub.

Thanks for the idea but the drive is not visible in My computer. and in the disk management i have only the option to go offline. nothing else.

thanks for the answer. but can you advise how to go about accessing it. i have already tried changing the cables. furthermore i have removed it now from the casing and tried to connect it directly to my desktop computer using SATA. but when i connect this HDD to the desktop my desktop gets stuck on boot screen and when i remove this hdd then my desktop boots properly. any ideas?

take the hard drive out of the casing and plug it into your computer with molex power and sata cable for data...if it still doesnt who up then you got a dead hard drive

To preserve your data, DO NOT format or initialise the drive. These are data destructive operations.

What is the model number on the HDD's label?

If you have tried connecting the drive directly to the sata data port and sata power ports and you still have an issue then I would suggest checking the disk for errors. It is possible that there is a problem on the disk and it needs to be checked. Download one of the many disk checking tools available online and run a diskcheck. If possible find a low level disk check tool and let it run for as long as it needs. If there is an error or bad sector or anything else that stops your pc from reading the data on the disk you should be able to repair it.

Nope neither will i format not initialize :-).
My HDD is Seagte Freeagent GoFlex 1TB. ST1000LM010

I tried connecting to my DEsktop PC which is a AMD Quad core but then my PC will be stuck on boot screen and once i remove this drive it will boot properly. I even tried to disable all HDD and do boot by CD but whenever i connect this HDD it will be stuck on Boot Screen.

also how to check for errors if none of the softwares recognize the drive??? can you advise a good disc checking tool???

Now i am thinking of using one of the 3 below devices. will they help? also any advise on which one i should go for.??
