Since the other Ic’s do not have power applied , you are basically taking their pins higher that the supply voltage…. this can cause destructive latch-up of the onboard transistors inside the ic’s you may or may not get away with it.

There is no mention of anti-static procedures in this article.

I would never come up with such idea. Great!

Very good work, what’s about data you get ?

Good piece of hardware.

without trying to build it I had some worries.
When U read out the image does it contain the spare area of the memory? I am afraid no.
Without this info it is impossible to reorder blocks to build up the correct image most of the cases…
I would welcome comments on this matter…

thx,
pepe

Thanks for ur idea man

I was not able to mend my player for past 2 years.
This will help me..Thanks

These articles, and Brandonu’s notes helped me recover video from a friends CVS camcorder that I accidentally damaged. The unit was ‘bricked’, it would only power on for a half second before shutting off.
I tried many different ways to mount the NAND image as a drive: OnBelay, dd, chip clips, etc. to no avail. I finally had to physically remove the chip and breadboard it onto a Schmartboard. From there I coupled it to an old Ethernut controller board (Atmega 128) and did a brute force I/O dump.
This was in fact the hardest part, writing the software dumping program for the ethernut to overcome some very noisy wiring that I had arranged. This finally produced a text-based data dumping program which ran over telnet. The data took 3 days to dump 128MB, plus 1 hour to convert from text to binary with a ruby script. But, the results were perfect.
I don’t recommend this method to anyone, but it sort of evolved on its own for me out of necessity and cost. If you are in a similar situation and need some encouragement you can email me madarp {at} rocketmail [dot] com.
Thanks guys.

@ Brad Martin-
Thanks for the comment. I had priced out TSOP test clips and found out they were way over my budget. Hence the hack. Lower melt solder would certainly help being a bit easier to work with and a little bit gentler on the chip.
One of the guys over at CameraHacking.com had come up with a reusable, non-solder clip out of a SchmartBoard. You can see fliers work at

It can make this even easier

@ antics
This was originally used by me as the first “legal” hack of the then new M220 model of “one-time-use” camcorders.

@ gregr
I’ll have to check that out! Thanks

Any questions, etc. can be sent to camcorderhack {at} gmail [dot] com

There is actually a dd for windows that does a fine job at dumping raw data. http://www.chrysocome.net/dd
