Bad Molex Connector

One of my HDDs in my RAID array failed several hours after installing a new DVD±RW drive today. I then remembered I had a problem with a molex connector about six months ago, so I put a Y-connector between the molex and the drive and now everything's fine.

Anyone else have problems with these? I feel very unsafe using these connectors. They seem prone to not make good contacts, even when brand new.

Coincidentally, I noted my problems with one in this very forum only
about an hour ago.

The metal tunnel the pin goes into can open up over time.

While they can be a problem, there isnt
any point in getting all neurotic about it.

Thats just plain wrong on the brand new.

When IBM selected these connectors they selected "cheap" instead
of "good". Saves maybe 50 cent per connector ans causes the
problems you describe. Although this type of problem is rare.
Same problem with the more "modern" ATX Mainboard connectors.
Good high-power, connectors exist. I was tempted more than
once to replace them all. But since the connectors on
mainboard, HDD, CDROM,... would be hard to replace and
void the warranty, I did not.

Usually the PSU side of the connector has gotten to "loose".
You can tighten it manually, if you are careful.
When the connectors are o.k. from the mechanical side, they
give good electrical contact.

You do need to push them home quite firmly. I think some people simply
don't insert them fully for fear of forcing them and causing damage.

True. But cable-to-cable connections have a tendency to not go in cleanly.
In that case don't push! Remove and try again. If you push in this
case, you can push some of the metal conectors right out of
the plastic casing. This can be repaired, but only by the
mechanically adepty. (Requires a needle to bend out the "hooks"
and reinsertion od the metal connector.)

No such risk with cable-to-HDD/CDROM connections, at least
I never had problems woth that.

I take it you are talking about the power connector on the drive.
I have a 60 gig drive that has the same problem.
