Fried USB Drives

[rounakr94]

My PC front panel usb ports went kaput so i replace thenm with new ports and soldered them but I missed a critical point that is the ports that I used were of a reverse type than the ones in my pc. So I fried 2 my USB drives and one drive is misbehaving( constantly mounting and ejecting itself). I tried a usb extension cable and it didnt work because it was too long. So my only way is to move my body bend down and connect it to the motherboards ports.
So why did my pendrives fry themselves? They were 32 gb sandisk cruzerblade( no warranty because free samples).

why? because you soldered the usb port wrong.

I soldered the port right, but the port was upside down whereas the antec port was right side up

I woudl still suspect that you wired/soldered something wrong. Are yo possitie that you did not create a short?

Nope, if it were a short then PC would have shut down.

This is the one I used: http://www.electroncomponents.com/image/cache/data/misc/connector/USB-2.0-EC-pcb-500x500.jpg

And my PC Cabinet had the ones where the 4 contact points were facing the opposite side of the pins

If it was between power and ground sure, but not neceassarly across the data wires to power/ground.

Its possible the port iteself is defective, possible your mobo header for the USB is bad.

It is a pretty simple troubleshooting process:
Take on of these: https://www.amazon.com/StarTech-Motherboard-4-Pin-Header-USBMBADAPT/dp/B000IV6S9S
If it works in the mothebroard header your front usb port is connected to then it is a problem with your port/wiring; if it doesnt work then it is a problem with motherboard and I would try a different header to see if just that header is bad.

lemme click some pics of the ports and upload them. Please wait for sometime.

My original ports: https://ae01.alicdn.com/kf/HTB1q1jvMpXXXXc0XXXXq6xXFXXXC/New-10pcs-lot-USB-2-0-Port-Jack-Plug-Female-Socket-Motherboard-Connector-for-Acer-Aspire.jpg_640x640.jpg

Ports I used: http://www.electroncomponents.com/image/cache/data/misc/connector/USB-2.0-EC-pcb-500x500.jpg

Original ports were pc mount so shell was little different but the pins were exactly same, Is the flux that comes with solder wire conductive?

Since you already had a port go bad it could very well be your motherboard/header.

With that said your assumption that because the moterboard did not shut off means that you did not wire it incorrectly is completley wrong though.
If you flopped the port then you would be sending 5v to the USB drives ground port, since most all flash drives do not have a diode to prevent this then this would result in dead flash drive.
If you have one of the data ports shorted to ground then the electrical data will still go to the motherboards ground but will also travel backwards through the usb drive (which as stated does not likley have a diode) and thus destroy it.

Actually the port was not dead but was rusted so it was unstable in speeds.

So it was because of flopped port then. Gosh why dont ports be of an universal orientation( I should have also checked them). For the time being I have disconnected the usb header and taped of the ports and am using the back ports.
Now I have to buy a front usb 3.0 dual port hub.
