NEMO IDE + SDtoIDE adapter

[VELESOFT]

I use WILD COPIER and FATALL with IDE port. If in IDE connector(40 pin) are connect HDD or CF card, then ide driver work. But if I connect SDtoIDE adapter to IDE connector then IDE driver not work. :v2_conf2:

I test more SDtoIDE adapters:
http://velesoft.speccy.cz/zx/sd_to_ide.htm

http://velesoft.speccy.cz/zx/sd2ide/sd_to_ide_b.jpg

I think the faulty IDE driver in russian software. If I use european software for ZX with IDE support then work correct with HDD,CF and SDtoIDE connector. :v2_thumb:

I can release both IDE drivers and we can compare it.

Hello, VELESOFT. I can confirm, that this SD adaptor didn't worked "out of the box" with DivIDE board. Don't have an idea about the probable cause, but may be the problem was in the lack of this "fix" you applied.
Regarding the issue, you described - try to format your card with different cluster size. And remember, that some SD card vendors DO NOT create valid partition table data on stock SD. To resolve this, again, you can reformat the card in standart PC with cardreader, or even create partition table explicitly with fdisk, paragon, whatever...

[sergey2b]

I have some adapter like this and It is working fine with divide
