Post subject:  SD Monolith Question
I have this card in. It was attached to a USB drive (gotta love the ingenuity). The USB drive went through the washing machine and tumble drier. At some point in the process the SD Card was torn away from the board and the pads have torn away as well.

I have no problem with soldering to the traces but have this question. For each pad there is a trace that goes to the bottom of the card and one that goes to the points above the pads. I presume the traces towards the connector are the ones to solder to?

It is pads for nand connection so since you not need read directly from nand, and card still working, you need regenerate only traces which goes to connector or that are connect to vias. And it should work.

I tried simply mounting the card, but had only 30mb showing, so I presume the card was using the on board controller from the USB. I tried simply mounting the card. Would that affect anything?

Usually if card shows small capacity like 8MB, 30MB it means that it not see nand.

Yes, One vendors garbage is another vendors re-purposed NAND(Refurbished is too strong a word)

I would agree with this, it is basically a NAND chip in a SD Card package. Once you fix the traces from pads to internals you should get a read of NAND, unless internal bonds also broken. Washing should have had no effect.
