  5. 5. But problem number 1: All flash drives has been broken into pieces. (Badly glued). 5 / 65
  6. 6. 6 / 65
  7. 7. And big problem number 2: All flash drives are FAKE . They ”pretend” to be 4GB flash drives, but actually they are not. 7 / 65
  8. 8. 8 / 65
  9. 9. 9 / 65
  10. 10. Looks like normal 4GB flash, FAT32 format 10 / 65
  11. 11. 11 / 65
  12. 12. Also looks like normal 4GB flash, FAT32 format 12 / 65
  13. 13. 13 / 65
  14. 14. FAR manager Looks like normal 4GB flash, FAT32 format 14 / 65
  15. 15. 15 / 65
  16. 16. 16 / 65
  17. 17. Trying to play copied file… WTF? 17 / 65
  18. 18. starting from position 7D790000 (hex) = 2105081856 (dec) ≈ 2007 MB all bytes are incorrect 18 / 65
  19. 19. Lets run expert tools… Looks like 4GB flash drive 19 / 65
  20. 20. ? starting from 2GB-position read speed increased from 11 MB/s to 32 MB/s 20 / 65
  21. 21. 21 / 65
  22. 22. Again half of flash-memory is bad 22 / 65
  23. 23. FLASH MICROCHIP INSIDE OF TOPKEEN 4GB FLASH 23 / 65
  24. 24. FLASH MICROCHIP SAMSUNG K9GAG08U0M-PCB0 INSIDE OF TOPKEEN 4GB FLASH 24 / 65
  25. 25. FLASH MICROCHIP SAMSUNG K9GAG08U0M-PCB0 capacity 16Gbit=2Gbyte INSIDE OF TOPKEEN 4GB FLASH 25 / 65
  26. 26. This is the answer… 16 G bit = 2 G Bytes ≠ 4 GB 26 / 65 http://www.samsung.com/global/business/semiconductor/productList.do?fmly_id=672
  27. 27. HERE IS THE PLACE FOR ANOTHER FLASH MICROCHIP CHIP SAMSUNG K9GAG08U0M-PCB0 capacity 16Gbit=2Gbyte INSIDE THE TOPKEEN 4GB FLASH 27 / 65
  28. 28. What now? How to fix? 28 / 65
  29. 29. 29 / 65
  30. 30. First, we need to recalibrate fake flash drives Ask Google about UdTools software, download and run it. For example, see http://forum.flashboot.ru/Files-file-158.html (This soft works only for specific flash microcontroller). 30 / 65
  31. 31. This is UdTools v.1.0.4.6 for chips: AMECO 8208, 6208A, 6208E (MW6208, MW8208) We use it to test and recalibrate fake USB flashes Use Google to find and download UdTools. For example http://forum.flashboot.ru/Files‐file‐158.html 31 / 65
  32. 32. UdTools automatically detects flash drives Just plug-in USB flash drives (1,2,3… ) and click here 32 / 65
  33. 33. ook at this Tab Low quality, high speed (it takes about a minute)… Best quality, low speed (about 30 minutes)… Use "Special Scan" only for very bad flash drives with a lot of bad blocks this mode reduces capacity of a flash drive 33 / 65
  34. 34. Here you can set ANY capacity… 4GB, 8GB,… 32GB,… …and make fake flash drive. Please, do not do it! 34 / 65
  35. 35. 35 / 65
  36. 36. 36 / 65
  37. 37. 37 / 65
  38. 38. Yes, recalibrating takes a lot of time . Also, 15% of flash drives are completely dead (see next slides). 38 / 65
  39. 39. 39 / 65
  40. 40. 40 / 65
  41. 41. 41 / 65
  42. 42. Bad soldering. . . 42 / 65
  43. 43. A box of crap — 150 dead flash drives. . . 43 / 65
  44. 44. Next problem: How to glue/stick/bond ”live” flash drives? 44 / 65
  45. 45. 45 / 65
  46. 46. We try to glue them again 46 / 65
  47. 47. By cyanoacrylate. . . But it takes so much time. . . 47 / 65
  48. 48. So we use ”batch processing” 48 / 65
  49. 49. put both pieces together. . . 49 / 65
  50. 50. stack it. . . 50 / 65
  51. 51. take some weights. . . 51 / 65
  52. 52. 52 / 65

  56. 56. especially edges. . . 56 / 65
  57. 57. regularly. . . 57 / 65
  58. 58. press down the weights with your hands. . . 58 / 65
  59. 59. So flash drives are bonded with melted plastic edges 59 / 65
  60. 60. 60 / 65
  61. 61. 61 / 65
  62. 62. 62 / 65
  63. 63. Yes, flash drive has fair 2GB capacity and bonded now but still ugly because of melted edges, and badly glued ”logo plate”’ also falling off . . . So impossible to present this to customers. . . 63 / 65
  64. 64. So we presented all these recovered flash drives. . . 64 / 65
  65. 65. . . . to students at career fairs 65 / 65
