You are right. This is an add on internal HDD (make Seagate). I have an 250GB Seagate HDD which is loaded with the WIN Vista OS. The system worked good when I initially installed the new 1TB HDD (for more than 6 months it worked). But now, when I boot the system, both the HDD's are being recognized in the BIOS but when Windows boots, I can see the 2 HDD in the explorer but when I try to open the folders in the 1TB HDD, it just vanishes.
The PSU that I am having is a local Indian brand (Zen The Master) that came with the Cabinet. Do you suspect it to be an issue with the PSU?
Zen The Master: Model# 400W-P4
AC Input Voltage: 180V - 264V
Orange | Yellow | Blue | Red | White | Purple | Black | Green | Brown
+5V | -5V | +12V | +3.3V | -12V | +5Vsb | COM | PS-ON | POK
26A | 0.5A | 17A | 20A | 0.5A | 2.0A | GND | | PG
Hope this information helps.
Thank you for your help.
Have a great day!!!
