iRiver CF mod with Transcend 64gb x400

[Sludig]

Hello,

I´m trying to do an iRiver CF mod with a Transcend 64gb x400, but ATA -1 error shows when I switch on the player.
I have read in a post that one user did the mod with this compact flash, so I want ta ask if someone know how to do it.
My iRiver is flashing and with Rockbox as tutorial says.

Best regards

Yes, I do all that here says, but I don´t find the problem

Hi, I had the same problem with my 32Gb x400.

I formatted the CF card using a CF card reader and computer and now it works fine
