Playback Logging is crashing on Mini 2G w/ 256GB card ONLY (iFlash SD/CF)

[cirdanlunae]

Device: iPod Mini 2g
Rockbox: Daily Build (20250618)
Adapter: iFlash SD/CF
SD Card: SanDisk 256 GB (Amazon link for the exact card: https://www.amazon.com/dp/B0B7NSTFLD?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_4&th=1)

Whenever I enable Playback Logging for lastfm_scrobbler on my Mini 2G and play a song, I get a crash.

Code: [Select]

*PANIC* (c145f41658-25dc_writeback_callback() - Could not write sector 815990 (error -3)
pc: 000724a8
sp: 4000af50
bt end
What I've tested:
-An original mechanical drive worked perfectly, so it isn't the iPod
-A 32GB SD card worked perfectly, so it isn't the iFlash adapter
-Ran 'badblocks' on the SD card, here's the results:

Code: [Select]

sudo badblocks -wsv /dev/sdb
Checking for bad blocks in read-write mode

I've been dealing with this for months at this point, trying to solve it on my own. Before I upgraded to version 4, this error did NOT occur. It occurred immediately after upgrading to version 4.

I'm willing to debug and troubleshoot this however I can to help solve the problem. The fact that this didn't happen at all before upgrading to version 4, and all of my tests, makes me think this isn't a hardware issue.

I'm buying a new 256GB card to see if the card I have is indeed the problem. Curious if the card is bad, but it's not reporting so with badblocks. Will report back with my findings
