SD Card needs rewrite every X time #301

Hi all!

This issue is extremely strange and particularly. But is not the first time I experience it.

The facts are. I have an Xstation with Sandisk 512 GB A1 Clas 10 (An SD card with the best quality, buyed new on Amazon by 60€). I installed it on September 2022 with around 300 games. It worked great. Perfect sound, no issues on FMV, quick load... I remember I was playing to PS1 during the Christmas diferent days with no problem, 0 issues. Everything great. After that my PS1 has been stored by 6 month.

My surprise comes now. June 2023. I take my precious PS1. I select a game and then happened: FMV have stutter, the audio have skips... WTF?? I've test 20 diferent games, and all of them have problems on the videos, music and loading moments.

After that, I did a copy on my PC with all the games on the SD card, formated the card on exFat (with the program metioned on the XStation guide) and paste all the games on the sd card. Now everything works great again.

The reason to share that is, that I experienced a similar issue with other ODE one year ago. With GDEmu on Sega Dreamcast with a Samsung SD Card 256GB. Every 6 month the data was corrupted on the SD Card or something, and It need to copy, format sd card and copy again the games to do work the GDEmu (the same as XStation). But... On GDemu I solved the problem buying a Sandisk SD Card. On Xstation, I don't know what I can do to solve it.

I've many machines with SD Cards: modern consoles, cameras, everdrives... This is the first time I see that the past of time can affect in any way the data inside the SD card.

Please, giveme light on this. This issue has made me almost crazy in the past.

Thank's

Hey, I have no solid answer: It should not happen. But what might be going on is that the card has weak flash cells that need lots of "reactivation" bit shuffling after a while. It is a condition in which the card controller moves data around a bit, to refresh the flash charge. It would be unusual on a Sandisk, but who knows..

To the general questions: Whether a marginal SD card causes noticeable trouble depends on how crucial performance is in each device. It is quite important on xStation, maybe less so on other ODEs? But they should all be comparable, I'd guess.
