A600/1200 IDE to CF storage card adapter. The CF card runs in "true IDE
mode", and looks like an IDE harddisk to the computer.
Hdtoolbox for the "unit is not a disk. type 7." problem. I think
that this is because some bit from the CF card identifies the card
as some kind of removable media. I think some CF card manufacturer
offer have software (most likely for doswintelpc)
to change that bit inside the card???
Note: The CompactFlash specifications say that the input logic high
voltage level should be at least 90% of Vcc. When using 5 volt supply,
it should be between 4.5..5 volts. However, compact flash memory card
manual from Sandisk tells, that a 2.4 volts at the input is
acceptable. In practise this kind of IDE to CF-card adapters seem to
work even without any voltage level adjustment.
