I haven't had much luck with my 340 Microdrive....
It works fine in the PCMCIA adaptor on a Notbook and works fine in the SDDR-31 USB Reader... but sometimes doesn't work at all in the IA-1.
It always makes a clickety-click noise when in the IA-1 and on first access it takes about 5 seconds or so, but then finally reads. For example: a DIR command will take about 5 seconds... list the directory and then take a few more seconds to get the number of bytes free.
I have tried various formats: FAT-16, VFAT-16 LBA... tried a few IA1 BIOS settings, and I can't seem to get a good combination. I have tried scandisk on the IA-1 but it says everything is fine. It just doesn't sound fine or work as well and quickly as it does in the other devices... and sometimes doesn't get recognised at all in the IA1.
Any thoughts or hints would be greatly appreciated.
By the way: The IA1 is working perfectly with my 64 and 128 Flash memory -- just a Microdrive problem.
