[pchelpers] Re: HDD appears and disappears

Jackie
I have seen this twice.
I had a 250 Hitachi that do it and a 30 WD that just did it. I spent
days TS'ing it and came to the conclusion it is the controller. Hitachi
and Maxtor were tow companies that for a while (I do not know if they
still are) used the same controller but either changed the CMOS on the
controller card or in some cases just the jumper to change the HDD size.
What I mean is Maxtor made all drives with the exact same size platters
say 120GBHDD but put but altered the controller either by jumpers or the
CMOS on the controller.
This practice is going away or hopefully ahs due to issues of stability.
If you can find the exact same drive on eBay or a friend that they drive
is dead (platters bad or read/write heads bad) but the controller is
good you can swap controllers and see if that fixes it. I know of
several that have had success in that area. In my case it is more cost
effective for me to toss a 250GB HDD and buy a new one then mess with
it. I can get my stock cheaper then Wal-Mart can so a 250GB HDD is
nothing to me in cost, in fact in some cases a defective drive off eBay
may cost more so I never bothered with trying it.

That the first thing I checked<G> The drivers are updated -running Vista

Ultimate ,XP Pro  MS Virtual PC 2007  I have since removed the HDD and
put 
another in its place and its fine. I thought maybe someone  on the list
has 
had that happened to them . Its odd  the HDD will be all right rebooting
its 
fine  then another boot or so down the road its gone.  I have a sneaking

suspicion it might be the power connector on the HDD . Anyways I would
love 
some input Thank You in Advance-- Jackie

Good advice is like good paint- it only works if applied.
