Hard Disk - Motherboard Compatibility

[rahulkhajuria]

I have 2 P.C.s as follows

P.C.1 : 865G/GVM3-V (MS -7101 V2.0) M-ATX MicroStar Motherboard
Pentium 4 Dual Core Processor
80 GB WD Hard Disk 1.5 Gb/s
512 MB DDR1 RAM
250 Watt Power Supply
Bought in 2006

P.C.2 : M2N68-AM SE2 ASUS Motherboard
ATHALON Processor
250 GB Seagate BARRACUDA 7200.10 Hard Disk 3 Gb/s
2 GB DDR2 RAM
400 Watt Power Supply
Bought in 2009

The Hard Disk on P.C.1 has the following thing written on it - 5v ... .48A
12v ... .50A

The Hard Disk on P.C.2 has the following thing written on it - 5v ... .72A
12v ... .52A

Now , I want to install the Hard Disk on P.C. 1 on P.C. 2 & Vice Versa .
However , I am concerned that when I try this out what if there is some spark or short-circuit due to some sort of power-mismatch because of which I end up killing one of the motherboards or HardDisks . Can I safely just swap the 2 Hard Disks ? Is there any more information I need to give regarding these P.Cs ?

What are the precautions in general that one needs to bear in mind before adding new devices onto a P.C. Or in other words , how does one check whether a certain device will be compatible with a certain system or not ?

I have never heard of hard drive, motherboard incompatibility. I wouldn't worry about it, especially since both of those drives are SATA so you don't even need an adapter! Only difference is one is 1.5gb/s sata and one is 3gb/s sata, and im pretty sure you can just use a 1.5gb/s cord on a 3gb/s, read the manuals for them just in case though.

Hard drive swaps should not be an issue. You may have power supply issues with pc 1. 250 watts is marginal. I would be uncomfortable with less than 300 watts with that setup.
