Hello Iain, |

Hard to tell. Even repeated memory tests may/maynot find your gremlin, |
11 |
i.e. bad memory. Also, just because it failed once, does not |
12 |
mean the mem/card is bad. Transients occur giving false bit readings. |
13 |
Sometimes you can delve into how the memory is actually made, but, |
14 |
most vendors protect that info, with NDA and such, mostly smoke screens. |

Here are a couple of links for your perusal: |

Sorry, there is not a clear answer. Keep it for non critical needs, |
24 |
upgrade to SDHC(fat 32) if your equipment supports that format. |
25 |
Fat 32 on top of the memory, helps with (bit)error masking with |
26 |
some enhance (undocumented) feature not part of fat 32. This is |
27 |
what makes reverse engineering, complicated on SD memory. |
28 |
You may need to upgrade the firmware of your equipment to support |
29 |
newer SD standards (SD 1.1 and SD 2.0). |
