Power isuues with HDD ST3160318AS

[bluefog86]

Hey guys,
I have a Seagate ST3160318AS 7200.12 drive that has been giving me extremely low speeds(3-4MB/s). I am going to replace the drive as data is not an important criteria here. But I want to know if the power supply could be responsible for this If I connect a new HDD to a screwed power connection , the new HDD could also be ruined How to check if the power is alright?

Why do you think this is a power issue in the first place? Seems unlikely to me. You could probably test the PSU with a PSU tester: http://www.ebay.com/sch/i.html?_trksid= ... r&_sacat=0

To me, when this question arises ("is the power supply ok?"), I just change the PSU.
Allow me to say that the PSU is probably the most important part of a machine and yes, it can completely ruin a hard drive before you even think "BOOM".

Those PSU testers are useless. Break out a DVOM and check volatages under a load.

The one I have attached the pic is reliable up today, but only a complete diagnose with LOAD and meter (possibly oscilloscope to weed out filtering problems) can tell everything.
However , it can give a quick go-no go indication + test of the power good section.

Usually, when it comes to drive throughput, Power Supplies aren't a big issue. If it's not working, you'll know it, because you'll see a lot of system hangups and strange and random hard reboots.

Everything else on the system is working fine.i guess there are several connectors that can power my hdd .how to identify them?

NOT TRUE.
