    I got an extra flash Omega about 3 weeks ago and at first it worked great.

    But in the last week I've had the "error 4" 4 times now. I put the memory card in the PC, run chkdsk and delete the files, then make a new saves folder.

    I realize the first time was because I shut it off too quickly. But I was playing baldurs gate and let my character stand still for 10 seconds, shut it off, then turned it back on after another 10-20 seconds, and error 4 appears.

    I really have no idea how to avoid error 4 appearing. I was playing James bond Nightfire and shut it off in the middle of a mission I had been playing for at least 5 minutes and the saves corrupted. Save corruption just seems like a when, not if question with this device.

    This issue makes the device unusable. Its a portable device and if I have to plug it into the PC 2x-3x a week to remove the corrupted files, it's useless to use at work on breaks or during travel.

    Shouldn't there be some redundancy in the firmware that creates a backup saves folder and if the main folder is corrupted it gets deleted and replaced with the backup? There could be an option to backup when first starting the system.

    The current design where a corrupted save folder makes all games not boot and the flashcard useless until you get it to a pc and clean up the mess it made is a bad experience.

    I'm using a ds lite us model and a SanDisk 32gb card.

    I have a lot of them across about 8 folders. Probably no more than 100 in any folder

    The problem is the corruption can be more pervasive than this. For example, I had one of my roms corrupt. I would say it's not enough to run chkdsk because there's no way to be sure chkdsk was thorough enough*. It's why I keep a mirror of my microsd card so I can reimage the whole thing if needed.

    I definitely agree. IMHO, they should redesign it so that the clusters used for a save are passed to a game and design it so only those clusters can become corrupt. Then the backup save folders (you'd need at least two) would be useful to recover good saves.

    * In theory it should be enough to do what you were doing: chkdsk, new save folder, copy over good files, and continue. But given a random rom was overwritten, I get the impression that either (1) it was an older firmware and a fatlib issue unrelated to an early shutdown or (2) a random shutdown can cause corruption all over the microSD (in which my idea won't work). Either way, the problem seems to compound itself like you've noticed. Using a clean reformat makes it happen less often. Also, it seems to vary by microSD card which makes me it's a contact or fatlib issue.

    PS - Sorry I can't really provide useful answers. I had a lot of problems for a while on the initial firmware/kernel, but I've had zero corruption issues on my latest microSD card. Like you, the corruption just seemed to happen at random no matter what I did. :/ There's virtually no way to actually debug the issue, which is the main problem.

    Thanks, I'll try to format and restore from backup. Maybe buying a few other 8gb cards might work too.

    I'm sure ez flash team is working on a firmware update to address this

    as told in the manual, once you meet an error, you have to scan and fix your microsd card. if you do not scan and fix the card. the issue will get worse over time.

    i don't mean to grave dig this thread, but this problem has gotten really bad for me. its happened three times now and when i save i make sure i wait about a dozen seconds after the save before i power it down and it still corrupted..... i have scan-fixed this brand new 8gb microSD every time this happened and now, as i type this, I'm completely reformatting the entire card, and not just the quick format, we'll see if that helps but I'm really pretty angry as this was not a cheap device. I'd really like to see this addressed in a future update or hardware revision or something

    What is the kernel version you are using? Did you use the emulator to play GB/GBC games?

    ive returned my ez omega to the eBay seller I bought it from as I cant stand this / dont want to always worry and have to do backups of game saves to the computer... getting an x5 mini

    the extra $50 is money well spent,

    game randomizer feature is cool too, and power efficiency

    Krikzz makes awesome stuff. makes me glad I got x3 gb instead of Jr too
