Apple - Installation/Removal / Re: Rockbox erasing itself after reboot. (iPod 7G Classic)
« Last post by rockbox_dev123 on February 05, 2025, 02:20:21 PM »I'll throw my $0.02 in and say to avoid SanDisk microSD cards with an ipod6g and rockbox.
Get a Samsung card as they're widely known to have fantastic compatibility.
Recently I bought a brand new SanDisk Ultra 512GB microSD from a brick and mortar store and it kept corrupting when used as a single card in an iFlash Quad with an iPod Classic (MB029LL/A*).
I returned it and instead bought a Samsung EVO Plus 512GB microSD which works perfectly.
This was also confirmed by a friend who had the same corruption issues even with genuine SanDisk cards in an iFlash Quad in an iPod Video.
However, I have a standard size (not microSD) SanDisk Extreme PRO UHS-I Card - 512GB in an iFlash Solo which works perfectly in an iPod Video.
Compatibility varies even with genuine cards and between devices.

Btw thanks for the help man, I was buggin out hours and hours. Glad this forum exists

Btw I wasn't aware of how bad the sd market is.
I've already contacted the ebay seller (a clown) and he told me he doesn't accept returns BUT to "ship it back so that he can take it back to his supplier and get a replacement for me".
Lmao he better return my money back quick or get his first very negative feedback with pictures included.

Hardware / Fake Flash - Does your SD card have Alzheimer's?
« Last post by Bilgus on February 05, 2025, 12:58:57 PM »Does your new SD card seem to just lose files after a certain limit?
Weird corruption issues?
Flaky reads and writes?
Did you buy it online?
You might have fake flash
What is Fake Flash?
Generally Fake Flash are factory seconds that have issues
Like lots of bad blocks or bad timings
Or even more common lately simply smaller flash chips
that have a fake capacity table to show to the user.

Windows and android users can use some of the tools listed here:
https://rmprepusb.com/tutorials/007-all-about-fake-sd-cards-and-usb-flash-drives/
Similar tools exist for linux too or use 'dd'
F3 (Fight Flash Fraud/Fight Fake Flash)
https://oss.digirati.com.br/f3/
'sudo apt install f3'
NOTE:
These tools have destructive testing methods some have non destructive tests too
Be advised you should back up any data you care about.
Ideally run these tests before you put any files on the drive

The supply chain has been 'corrupted' ebay is ebay and you can't even trust amazon
to even send you the sellers product (THAT THE SELLER BOUGHT AND SHIPPED TO THEM!!)
So go brick and mortar haven't had a bad one bought local YET. (Except 1 PNY)
But I still run a capacity test before I spend hours transferring files because of the bad experiences from online sellers
and PNY

Theming and Appearance Customization / Re: Any possibility for conditional %Cl?
« Last post by RetiredTeacherGuy on February 05, 2025, 12:26:05 PM »You missed the final %Cd adding that mkes the second one work
but its not wanting to draw into Viewport 'c'
I'll keep working with it till I get it or give up..
I really want the %VB thing to work might have to do some extra processing to get there
this works but IDK if is actually going into 'c'Code: [Select]#%?mp<|%Cl(0,0,160,160,b,r)%VB%Cd|%Cl(0,0,140,140,c,c)%VB%Cd||>
%?mp<|%Vl(c,0,0,-,-,-)%Cl(0,0,170,170)%Cd|%Cl(0,0,140,140)%Cd||>
%?C<%Vd(c)|>
Even with the second %Cd that I had forgotten, I still do not get two different sized (not cropped, but actually proportionally sized) images. Do you?

Yes this is probably fake flash, I have seen similar on a 5 year old card
when it shit the bed but if you just bought this then yes fake flash.
