Re: iriver H320 freeze after ATA power down

Hi John,

That all sounds eerily familiar. It seems to me that I ran into similar
trouble when I installed a 32G CF in my Mpio HD300. I believe Marcin
did the bulk of that porting work - you might search the repository
history for any ATA sleep recovery issues with the HD200 or HD300.

The only detail that I don't remember exactly whether I had this
sleep-and-never-wake problem only with the original firmware. Rockbox
*might* not have exhibited the same issue at all.

Regards,
Mike

So I bought some PATA to CompactFlash adapter and a CompactFlash to microSDXC interface (https://www.aliexpress.com/item/High-Speed-Dual-Micro-SD-SDHC-SDXC-TF-to-CF-Adapter-MicroSD-to-Compact-Flash-Type/32733162720.html)
