Win 7 won't recognize 4 TB USB hard drive
Purchased a brand new Seagate 4TB USB 3 external hard drive..."Seagate Expansion Desktop Drive"...
When I connect to Win7 home PC...the Seagate will NOT show up in either Computer or Disk Management...
Plug into any USB port and I get the audio "ding"...notice shows up that the drivers are installing...
BUT...does not appear in Computer or Disk Management...
When I connect it to ANY OTHER Win 7 PC the Seagate shows up and works as it should...
SO...I expect it's something with this particular PC...
It has 3 HD's attached to SATA ports, 1 CD drive...When I plug in other USB drives, flash drives etc...they work...
Any ideas on trouble shooting this problem...???
Thanks...

I should also have asked if it shows up at all in Device Manager. Specifically, is it under "Other Devices" or as a disk drive with a red or yellow flag next to it?
Tell us more about this specific PC. How old is it? Does it have USB3 port? What version of Windows 7 is installed there?
ASKER
CompProbSolv....I get 512 Bytes per Sector....4096 Bytes per Physical Sector...it does NOT show up in Device Manager at all...meaning no red or yellow flags...
Noxcho...this PC is about 4 years old...From Micro Center...their PowerSpec brand...
OS on 120Gb SSD...Data on 2 TB SATA...and a backup drive also 2 TB SATA...
Win 7 home prem SP1 i7-2600 3.4Ghz 8Gb RAM...
I found 6 Msoft updates...downloading them now...
I have another Seagate 4 GB USB drive that I use on a different computer...I swapped the drives
between the 2 comptuers and NEITHER Seagate will be recognized in the subject PC...
BOTH Seagates are recognized in the 2ed PC...
So...it's something with the subject PC...maybe the Msoft updates will get it....
Will report back...

As was already asked, do you have a USB3 port on that PC and are you using it, or are you connecting it to a USB2 port?
Does the disk have an external powersupply, or is it only powered by the PC? Have you tried connecting it via a powered USB hub?

Do these drives have their own power? Or are they powered from USB port of this PC? It could be missing power which your PC does not provide for a desktop drive. I know this problem.
Another question - does this PC detect the USB sticks or other USB drives smaller than 2TB?

rindi was quicker than I by typing :)

Yes...have USB 3 ports on BOTH PC's...
Drive have own power supply...
On the 2ed PC...NOT the problem PC...I have used one of the Seagates on USB 2 with no issues...
Reminder....
I have 1 brand new Seagate 4TB USB 3 HD with power supply...
I also have an OLDER Seagate 4TB USB 3 HD with power supply...
The OLDER Seagate works on my 2ed PC in either USB 3 port or in USB 2 port...
The new Seagate does NOT work on the subject PC...but DOES work on the 2ed PC...in either USB 2 or 3 ports...
Noxcho...when Rindi is around you gotta be really "quick"...:<)...
checking now to see if my Msoft updates are finished...

What about the drive or usb stick which is smaller than 3TB drive on subjectPC?
ASKER
Well...there were about 6 updates...installed...then there were 8 more updates...
After those were installed the PC now recognizes the OLDER Segate but not the NEW Seagate...
The NEW Seagate works on the "other" PC...
So...gonna solve the problem by swapping the Seagates between the 2 PC's...

What is the different between older and newer drives? Power? Interface? Size?
ASKER
As far as I can tell...there is NO difference...other than the color of the case...
Both USB3...both ext power...both 4 Tb...both advertised as Seagate Expansion Desktop Hard Drive...
