Files Always Corrupt

[washcroft]

Hello,
I'm a new owner of the X2 and I have it running on 1.02.04 with 2x 64GB Samsung MLC cards, however I'm finding that 95% of the files on both cards are always corrupt - the files exist but their content is nothing but NULL bytes (0x00). This is happening with the cards formatted as both FAT32 and exFAT.

Is this a known issue with v1.02.04?

Best Regards,
Warren

I think this is a known issue in the version, contact your seller and they'll give you a different version to try

Thanks! I've contacted niko.

I've never seen that one before - have you tried testing the cards with h2testw?

I'm sure he'll be in touch soon to run through some things with you

Have you formatted memory cards inside unit as well ?

I haven't but can do - as it was affecting front and rear cards at the same time I didn't expect it to be card problem.

Have you formatted memory cards inside unit as well ?

Yes, FAT32 and exFAT formatted on a PC and exFAT formatted on the unit. All three have the problem, seemingly only once it starts to loop?

You wrote 95% of files are corrupted, I assume 5% of files are OK.

1. Are those 5% in sequent order ?
2. Are they at the end of memory card ?
3. Are those good 5% files on both rear and front cards from same recording time, or random ?

I am trying to understand if its could be memory card or FW related.

It's definitely worth trying them as it could be both cards are fakes depending on where you bought them from.

You can get the software from here:

It takes around an hour a card to do a full test if they're ok.

I will inspect the cards later and report back.

Hmm... I am doubting the authenticity of my cards now, files filled with zero bytes would be a likely indicator of fake flash. I will test and report back.

Can you share a link where you bought cards from.

OK - So it transpires that I have fallen victim to fake flash! I had no idea this practice was so widespread...

Sorry for the unnecessary panic, I am happy knowing my corrupt files isn't anything to do with the X2.

Sorry to hear that. Hope you can recover your money via PP or Credit Card centre.
Can you share the place ( link ) you bought them from. This would serve as a warning to other buyers.

It was a random seller on eBay, eBay returned my money straight away. I have now purchased Samsung Pro MLC cards from a reputable store and have verified they are genuine before using them.
