Error when writing a image to CF card

硬盘爱好者

I get an error #21 when I try to clone a image from a 512M SimpleTech CF card onto either a SilicomSystems CF or a MemoryTech CF cards. I am clonimg a raw image. It appears to work okay with the progress bar going to 100% but then generates the error. The contents of the card appear to be ok as the equipment the CF cards are inserted into run okay.
If I use a image from a SilicomSystems card I can write it to any of the 3 types, unfortunately the image I need was taken from a SimplelTech card.

Despite the label saying they are the same size, in actual fact most flash drives vary just slightly. So, if your SimpleTech card is just slightly larger than the other two, you would get an error at the end, when the last couple of sectors cannot be written. Since these are usually unused anyhow, all appears to be fine (and often is!).

Likewise, if the SilicomSystems card is actually the smallest, that problem would not occurr when writing to the other types.
