After the old hard drive failed, I put in a Toshiba MK8007GAH 80gb hdd, which I believe is compatible. I've been able to format it on my laptop (FAT32), also scan it and transfer files, all seems ok. BUT the drive will not ever boot up in the player, either using the iriver firmware (CHECK HDD CONNECTION error) or the Rockbox software, which previously worked (various ATA errors, 1, 11 or 32).
The player FM radio still works. Have tried updating its firmware using the NAVI button menu - doesn't seem to work. The firmware on it now is H310 1.30 E. I've another identical machine, and its firmware is H340 1.29 J. Could this be the problem - and if so, how do I change to/transfer the correct firmware. I've tried the other player's hard drive in the 'faulty' player, and it works perfectly, so I don't think this is a hardware problem. Apologies, I'm not v.technical, don't really understand about patches/bootloaders etc. Many thanks.
