Recently i have added new 1 TB SATA hdd into my pc. when transfer files from old hard disk to new one its disconnecting and reconnecting again and again. what may be the problem.

I saw some of my SATA power cables not working when i connected my secondary HDD into my PC.finally connected to one power cable.

is this time to change my SMPS? i think my power supply problem. Zebronics 500W is my SMPS.please help

Welcome to the forums, newcomer!

You should list your specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

include the age of the PSU and the version for your OS.

Zebronics 500W is my SMPS
That is not something I'd call a PSU due to it being dodgy.
