Post subject: | Bad NAND? Or bad read? |
For the sake of learning, I ripped open a 16GB CF-card which has 4x FT32G08UCT1-B7 and Phison PS3016-P9 on it. When trying to read the ID of the chips I got basically "00000000" or "2121212121" or similiar. There's no exact match for the chip in the db but FT32G08UCM1-15 seems to be closest so I used that one. Dumped all four chips without any problem. However, I do run into problems when I check the dumps in bitmap viewer. Image 0 looks like this: Attachment: Image 2 looks like this: Attachment: Is Image 0 a dead chip, or has there been some error during the dump? Image 2 shows a lot of bit-errors in the SA. Is that because of a bad dump? (VNR 2.4) |

Hi , Please Post Post Photos Of Device And NAND Flash ,You Need To Update Version Of VNR to 3.9 ,Speak To Katarina Please .You Said 4 Chips Or 2 Chips ? . Are There 2 Parts Per Each 4x Chips or 4x Parts Per 2x Chips . PS : Its Very Interesting To See This Controller ,I Have Always Seen SM2236 Under Its Own Name Or Sandisk Name |

It's four physical chips, all marked FT32G08UCT1-B7. And I cannot upgrade to VNR 3.x, I'm kind of stuck with 2.4. |

Google suggests that these are remarked by Kingston. The 64Gbit versions are claimed by some to be Toshiba chips. https://www.insidegadgets.com/2013/07/02/inside-the-kingston-60gb-ssdnow/ https://proclockers.com/review/kingston-ssdnow-v300-128gb-solid-state-drive-review/ |
