Hi. Today I read a dump from a nand with 12 BB, with the option of hard copy. Then I scanned the file with your software and also, it does not detect any BB in the dump... I fixed the dump with tnm5000
Hi Catalina,
Sorry for the delay. The scan bad block S/W tools scan the whole block as all 00h then recognize the block is bad block. According to the image file. The bad block flag on block 3/5/15 are all 0xFF and it seems not the bad blocks. Can you assist to check if this is the image file with bad block as 3/5/15?
Thank you.
Hi Catalina, Yes. Please provide us the test dump to check why the SW can’t detect the bad block images. Thank you and have a nice weekend.
