ipod 5g with "big disk" doesn't hdd spin-up after hdd spin-down.

I used ipod 5g with custombuild(lba48, phy sector 4096, log sector 16384) and rockbox works fine till 22315(this is my latest version).

But, when I download 22588, rockbox didn't work clearly.

On 22588, when hdd goes to spin-down, hdd didn't spin-up correctly. very-long delay and sometimes error printed(like error loading playlist, or not shown error, etc).

My hardware is ipod 5.5g(64mb) with HS12YHA/I(120g, sector size 4096, supports lba48)

This task depends upon

Why are you reporting a bug against your personally modified build?

Does this happen in the official build with non-modified hardware?

I don't knew "lba48, phy sector 4096, log sector 16384" is unsupported funtion. I don't have any non-modified hardware, so I don't know this happen in the non modified hardware.

Usually we don't take bug reports for modified builds, but it seems odd to me that this would occur. I think we can leave it open until at least someone has an explanation why it happens and we're sure its not a more general bug in playback.

I don't think any supported targets use a 4096-byte sector size, so it's not inconcievable that there are disk-handling bugs that manifest only on homemade hardware. Are you able to get your hands dirty and do some forensic digging into the code yourself?
With a 120GB disk, you shouldn't need to enable LBA48 (unless I'm thinking wrong). Also is there any chance your modifications did not apply cleanly when you updated the rockbox build?
