Ok, Asus Netbook Eee PC 1001PX to be precise. 2010 vintage running XP, nothing special but I think I've killed it :'(
As i've done many times before I connected a powered USB hub - however, this time I used the wrong power adaptor for the powered hub. My mistake, I just picked up the wrong one. However, it was a 12v PSU as opposed to the 5v one for the hub.
The netbook was switched on, but when power was applied to the hub the netbook immediately "died", and a whif of smoke came out of the hub. Ok, the hub is now dead - but I'm wondering about the netbook. I'm suspecting it's dead as well, it wont power up.
If I can get the hard-drive out of it is it possible that I can install into another (identical) machine & carry on - assuming its survived that is, or even connect it as another drive to recover data - surely nothing to loose is there? have to work out how to get the hard-drive out first.
What a silly boy :-X

Pull the cover off and have a nosey Rob, you might be very lucky :-\

I've got inside it (thanks Youtube), but the bad news is that the only real part having "that electrical smell" is the HDD itself. :'(
What's the worst that can happen if I install it in another machine - not as the boot drive?
-
I'd remove the battery and mains supply from the netbook for a minute or two then try powering it up again.
Disk would go into an identical machine and keep working. It's unlikely that it's taken the disk out. The built-in "crippleware" in XP would probably try to claim that you're using the OEM build on another machine, since the motherboard and network adaptor identities will change, but you might just need to do another online registration to fix that. not sure. :-\

Really? That's not good. It's a poor design of USB hub (and laptop, frankly) if sufficient current has got into the machine to do that.

Tried that - no good

I've a copy of win 7 ultimate here but it would need to be a total re install but as Kevin says, if the hard drive smells then its probably knackered :(
Have you backed it up recently ?

Ok, have put HDD into another machine (desktop), by just connecting a spare SATA power cable. Machine wont even power up :(
My conclusion is that it's a dead HDD.
Looking at the way the machine is built, there are only 2 USB ports. One is on the motherboard, the other is on an expansion board which the HDD connects to - with that board connected to the main board via a long ribbon cable. It's the expansion board USB that I connected to - so suspect that the HDD was one of the first things to get the 12v when it was connected.
I've used this powered hub with this machine loads of times so am quite angry at myself. The thing is that the power connectors on the two problematic devices are the same size, I'd had a bit of a tidy-up and picked the wrong one up.
Bumbles ......

I've removed the PCB from the HDD (dead easy as it just snaps in place) after removing 7 screws.
In flipping the board over there is very obvious electrical "trauma" on some components adjacent to the SATA power interface - am talking about a small chip which has split apart :o.
So, I've just bought an identical used HDD from ebay with the objective of using its PCB - what can possibly go wrong ::)
I'll keep you posted ...

If the part numbers are completely identical then that's been known to work..

They are :y. The seller posted a very detailed picture of the label on the drive on ebay - it was quite cheap as well.

Good luck!
And don't do it again ;)

Thanks & yes Dad :-[

Kevin Wood - its ASUS, of course its a flawed design.
Lincs Robert - I'd treat any part of that machine now as suspect. In a proper design, it should have just wiped out the on-board usb hub. The fact its done more damage suggests a lot more may have got fried.
Good luck anyway, but dont throw too much money at it

Anyway, back to fault finding my Openpeak Joggler - which I've just done exactly the same thing to. 12V mains adaptor instead of 5V, and it wasn't best pleased. :-[

The PCB revision is only part of it, you need to have the same firmware revision as well for it to work.

You may well find a few challenges there as the PCB will have a non volatile memory device on which is stored information relating to the platter. This tells the driver where the failed sectors are etc and often it looks for a specific code on the platter before it will run.
Of course you could look to use the drive electronics as a component mine and hope its just the PSU thats failed on the original drive.

Fair point Mark. It's a bit all/nothing approach really with the board. The way I look at it I've got nothing to lose. I've essentially written the machine itself off as I cant see 12v onto a 5v rail doing anything any good. I've got real physical damage to the HDD PCB but who knows what else has been done to the motherboard or other modules/memory etc.

Always worth a try just don't hold out too much hope, I have tried it a few times in the past with varying success

As for the main machine.
Generaly, a power faul such as this will take out the associated driver chip and anything else connected to it, upstream is normaly ok.....
You say the HDD is effectively a USB device plugged into a USB bridge inside the PC?

I'm not really sure if it is or its just the way the hardware has been packaged. On the motherboard there is a connector marked DAU CON which connects to a ribbon cable. The ribbon goes over the HDD to a smaller card (marked I/O) and has the following connected to it:
1) HDD (Combined SATA/Power connector)
2) Fixed Ethernet RJ45 connector
3) USB port (this is the one that received the 12v)
4) Audio jack
5) Internal speaker connector
6) Cable to screen for camera/mic/LED - main screen is connected direct to motherboard
I think they have just extended some of the connectivity to this I/O card - it has chips clearly connected to the USB socket and RJ45.
Does this help?
