Is there a way to only use one part of the Pair element. By that I mean applying the 'split by block' but not 'join by pairs'. I have a Sandisk chip and I have seen solutions where splitting by block and then applying joining by dump is the right mix. Is there a way I can do this in VNR?

Yes there's at least 3 ways to do it in VNR

1 - Separate element does exactly what you need (page 21 of manual part 2)

2 - Offsets element (page 26 of manual part 2)

3 - Extract/Skip area functions from toolbar

Let me know page size and dump size to calculate parameters.

Use Separate element:
Number of partitions = 2
Movable block size = 17664
Area size = 38672007168

If you need a deeper assistance with the case drop message to Patryk (patryk@rusolut.com) he's our Sandisk expert.

After that do we us Unite? If so I presume we use two inputs and what would the area size be?

How many dumps/chips you have?

One dump, one chip.

Then there's nothing to unite.

Indeed hence my initial question. Several solutions in the PC3000 database have unite by dump after splitting blocks. All the cases are single chip sandisk cases.

To give you a little background. Rusolut support signed in last week and helped with the case. Using the stadard Pair - Pair elements still leaves corrupt data. I looked at similar cases on PC3000 and the join by dump is used in many successful Sandisk single chip recoveries.

How many planes do you have? You can check it in configuration window.

Use Pair Element:
Number of planes = 2
Movable block size = 35328
Area size = 38672007168

Then build Markers Table.

If you need a deeper assistance just let me know.

Unfortunately the software will not allow it. It will not allow changing block size to anything other than page size. Same with the area size (unless I missed something?).

Any other advice you can give would be appreciated.

can you post a screenshot of elements window, and include the structure?

I had one where I needed to add banks. I intended to setup like (plane)->(Bank)->(block)-(Page)->(data + SA)

but I could not set Bank. In the end I got rid of plane and started with Bank and it worked. I may have been doing something wrong but if previous elements aren't right things wont work.

If it is standard Sandisk, you don't have to split dump, so Separate element isn't necessary here.

I need to know one more thing: can you tell me or make screenshot of parameters of first pair element.

Also, can you explain me why you cannot edit parameters of pair element? This element has three fully adjustable parameters. You can change text fields of this element by pasting there value.

If to two inputs of unite element you connect same dump, in results, depend what parameters you type, you will get JBOD or RAID0.
