Some days ago i saw something weir on my emule, one file was with progress line in diagonal stripes yellow and blue and says ERROR on status them when i turn on again mye emule all was fine and the file comming to finish but it doesnt complete the hash and remains there

Any Ideas?

I had that once IIRC it completed after I rebooted and restarted my computer and eMule for about 3 times. Dunno how and what tho...

I've had that happen a few times. One time it just wouldn't complete fully, and I had to re-download. But a few other times what I did was rename the corresponding part file to avi, then removed it from emule share directory (so when i reload shared files, it ain't there no more ) and then I readded the file to download (from the link) and used MorphXT's "import parts to file" and it added all of it to 100% and worked and kept the hash. You could try it if that made any sense.

I had that problem once.
I've closed the program, and when I started it again, it made the hash check just fine.

Could it be that there is not enough free space on the disc with your incoming files?

I will try grind method as the other thing i have tried, thanks
