Hi.
I have a new SEAGATE Barracuda 2 tb internal HDD in a dock I have been using for a while, with another HDD. No problem there, but I set it (the other HDD) up on another PC running Win XP. Once formatted the 2 HDDs I use in 2 different docks work on my laptop.
Somehow I must have forgotten something or there is something I don't know about setting up a new HDD using Win7.
My laptop isn't recognizing the new HDD, other than finding the drivers ( I guess, no real ID on what the drivers are for, but only 1 new device leads to the conclusion...).
I am not totally ignorant, but I don't know what to do next.
Can someone help me find my way?Correct me if I'm wrong. Is the 2 TB HD not recognized on a laptop I PRESUME is connected internally and your trying to install Windows 7? What laptop brand/model and kind of Windows disc you are using? These are docks you are using with the laptop as well ? ?
If you are using both try with just one.
From a cold boot check in Disk Management and see if the DOCKED drive is even reported...it should be.
Doesn't matter if the drive was setup under XP or not...*The drive is the only one in a dock, I removed the 2 other working HDDs.

*I only mentioned XP to delineate the different environments, as I was able to format the other 2 HDDs in XP, and not now using Win7...

*What does the term "cold boot" REFER to?  I have rebooted 2 times with the drive connected to the laptop in the dock. I can see a device  (unknown) displayed in My Computer, but no way to format it I can figure out. Which is why I am here... Device manager gives me a long number which is the new HDD, I assume, but where do I go from there to format the drive?
Does it show up in Disk Management ? ?Yes, as disc 1.
Except for my C drive and D drive, there is nothing else ACTIVE on my laptop.Well right clik it and select Properties...
Report back with your findings...There seemed to be a lack of grasp here, so I went online and kept trying on Google search until I found someone who put together a few pages of "How to Format a HDD in Win7", and "How to Partition a HDD in Windows 7", which was my main problem. Had to partition the drive before formatting it, worked like a charm .
Now I can reformat my laptop after using the HDD as an external storage drive and saving my app files, etc
.Got something nasty not visible to any anti virus or malware software; Kapersky, SpyBot,  Avira ,CCCleaner, nothing found whatever it is filling my RAM and turning my laptop into frozen sludge.
Most of what I have program-wise is kept on docked HDDs (5 TBs now), so my laptop is pretty clean.No lack of grasp at all...i was waiting on the Disk Management info...
Glad you got it sorted...
