Ipod 5.5 / iFlash sata V10 / Transcend 430S 256gb issues

[dedero]

Hey there,

I'm a very happy user of Rockbox in Clip+ and Clip zip and I'm very glad developers keep mantaining it, hats off!

Now I want to suffer a bit and few days ago I bought a broken Ipod 5.5 and I installed an iFlash sata V10 (the one for M.2 drives) with a Trascend M.2 256gb disk and 70% of the times I use it, I get

PANIC - dc_writeback_callback - Could not write in sector 19 2784 (error -53)

I've tried to turn off directory cache as this workaround suggests https://forums.rockbox.org/index.php/topic,53166.msg245605.html#msg245605 the things got much better, this error happened only 30% of the times I use it, however every time I reboot the Ipod or shut it down, the directory cache is activated again so the error comes back, any hint what I'm doing wrong here? is there a way to turn directory cache off permanently?

Info:
- I use the latest daily build from September 2022
- The iFlash with the Trascend disk works perfectly in the original firmware, I could sync almost the whole 238gb of the disk with no problems except of the heat which is not bad.

Did I bought the wrong iFlash combination? do you suggest replacing it with a SDXC solution?

I would like to make Rockbox work otherwise I would need to convert my whole FLAC collection to ALAC and I would like to avoid that.

Any suggestions is welcome!

Cheers

Please go into the system/debug menu and dump the ATA info.  It creates a txt file on the drive.  Hopefully with that we can figure out if something needs to be done differently.

Hi, thank you!

I dump the ATA info but I got a binary instead, I didn't see any other option related to ATA info, and I keep getting the binary, I hope it helps

Cheers

Thanks for generating the dump!  Based on that we should be properly detecting the mSATA thing as an SSD.

BTW, I now have one of these ipods and the v10 msata adapter, along with a generic Chinesium mSATA SSD. I need to take everything apart to do the swap (which won't happen for a few days at least) but once that's done I expect I'll be able to recreate this problem pretty easily, and hopefully figure out a way to resolve it.

Would be awesome! thank you very much!

Would be awesome! thank you very much!

Please grab the latest dev build for your iPod from https://build.rockbox.org/ and let me know what happens.

Thank you very much for the info, I installed it few hours ago and so far everything is going great, I loaded the music using the original firmware and disabled directory cache and it's very stable now without any issues.

I'll keep using it and testing and give you a message if something brakes.

Thanks a lot for your efforts!

Given that data writes are what were triggering problems, it would be helpful if you could try out copying stuff to the drive from within rockbox, and generally doing things that trigger writes.

Thanks, I've tried writing actions and now the error came back.. I tried restore the ipod with itunes, install rockbox, copy the music in the OF and the same, it triggered the error back again now it got back to the original state like before the fix

Thanks for the hints
