upgrading the HDD of desk top

[kda rajesh]

i recently purchased a desktop C2D E8200,1GB RAM, G31 GIGABYTE M/B, 250 GB SATA HDD. I already have a portable external HDD SEGATE IDE 250 GB. THE PROBLEM IS WHENEVER I CONNECT THE EXT. HDD THE CONNECTIVITY IS UNSTABLE, WITHIN FEW MINUTES OR WHENEVER I TRY TO TRANSFER SOME HEAVY FILE THE HDD VANISHES FROM 'MY COMPUTER'. CAN I REMOVE THE HDD FROM ITS CASING AND FIX IT IN THE DESKTOP. WILL IDE HDD RUN ALONG WITH SATA HDD? PLS HELP.

yes it will run along sata HDD. when you connect it externally, make sure the base is still and the wires don't move. if the hdd has an os on it, remove it before connecting it internally. try to keep it cool by cleaning the cabinet from inside.
