Subject: Transfer Files Using SDHC to USB adaptor with a problem

Hey Guys,

Do you transfer files using an HDSC card USB adaptor ?

Do you ever use these USB 2 SDHC adaptors to transfer files and
had one that just wont work right because of a stuck READ ONLY problem ?

I bought this TARGUS usb HDSD CARD adaptor at walmart (or target) and it would not
work right. Nothing Id do would make the card
writable. Not taping the switch on the card or anything else easy.

After some research on the internet I found it was not the fault
of the HDSD card but the little USB adaptor thing.

There is a switch inside the adaptor case which contacts with ground
to enable writing the card. This switch is simple and activated
by the slider switch on the card. If the MFGR had used a microswitch
within the adaptor it might have cost them more to build but would be reliable.
Instead of a microswitch, its like a simple beryllium copper spring thing.

I opened up this case and ripped out the switch with
needle nose pliers then used a soldering iron to
solder the switch connection to the shield ground.

Now you can not write protect the cards in this adaptor even if you want to.

It would be possible to build your own more reliable switch
to the outside of the case. Simply shorting the option to ground.

Now I am able to use any SD like card to transfer files
by USB and not worry about this problem.

Just thought Id let you know it's a bit hard but R/W can be set to W permanently
rather than buying another reader adaptor simply with a spot of solder.
Ripping out the switch was risky since force was necessary.
I think the switch might have been ok to stay in place.

China made things today are like the Japanese things of yesterday.

Lacking quality.

 Toxicology Note: Beryllium has an interesting toxic quality, if they put it
in copper jacketed bullets, human wounds created by such a bullet
would not heal unless the contaminated flesh is first cut away.
For some reason, this element stops the bodies ability to heal injuries.
We seem to be made of regular star stuff and not supernova stuff
since all the heavy metals over iron ( if I remember right ) are poisons to humans.

Best Regards;
geoff
