External HDD not functionnally in my own PC, freeze others PC

[dmtiam2591]

Hello guys !!!

Have to say this first, sorry for my English.

I have an external HDD: Seagate Expansion Desktop External Drive 2TB USB 3.0, you can see more here: https://www.youtube.com/watch?v=rWTSHSQ92dg We have 3 happily years with each other, until yesterday.

I format my Seagate into 2 partition/volume: G-1tb, H-1tb. My own computer already have another seagate hdd, 320gb, I format it into 2 partition, C-300GB for Windows and D-20GB for documents (docx, xls ...)

Everything works fine till yesterday, my computer only recognize the G volume, the H volume appear like the A volume (DVD,CD) with no disk inside. And access to data on G volume is very slow. If I try to access the H volume by any means (right click => properties ...), my computer nearly hang (my computer hang, s Firefox, MPC, Word, Excel, ... still function If it already opened)

If I plug that external HDD to other computer, that computer still recognize my HDD (appear message like "found new hardware...", "... installed and ready to use"), but after that, It freeze.

I've tried some method like plug that drive to PC then start with windows, change my usb cable with another ... Nothing works

Here is my specs:
Main ASUS M3 N78 VM
CPU AMD Phenom X4 GP 9850
RAM 2*4GB bus 800 MHz
VGA MSI HD 7790
OS Windows 7 Ultimate 64bit

Plz help, I will be very appreciated.

To simply put: It is easy to understand if you group as separately.

1. Seagate External HDD 2 GB
1.1. G: drive = 1TB -> to access this partition, is slow, which cause the window explorer to hang. But other programs do run, no problem.
1.2. H: drive = 1TB -> system read it as optical drive; unable to access.

The chance is that you external HDD 2 TB is about to fail.
For G: drive, if it allow you to copy data, you have to do it fast, and not to remove and move to another computer.
Once you move &or remove the connection, the next connection may failed.
For H: drive, it may be failed.

Note:
Check if the connection is loose or not. The USB at the external HDD end, and at the computer end.
USB connection loose may also play the part of this problem.
Do use another USB cable, to test if it is the USB cable fault or not.


As for the other HDD 320 GB which has no problem, don't mentioned as it could confused.
It is easy to use point format.
