BackupMii: What means "ECC Failure (Corrected)"? I made two Dumps, one yesterday and one today. Yesterday I only got Bad Blocks (ok, I know). But today I got one time "ECC Failure (Corrected). What means that? I know that a "ECC Failure" in the Installer.log is normal, but what means that Error with corrected while a Dump?http://forum.wiibrew.org/read.php?25,18521,18521#msg-18521Mon, 20 Jul 2026 11:51:38 +0200 Phorum 5.2.23 http://forum.wiibrew.org/read.php?25,18521,28316#msg-28316 Re: BackupMii: What means "ECC Failure (Corrected)"?http://forum.wiibrew.org/read.php?25,18521,28316#msg-28316 wiiman BootMii BetaSun, 09 Aug 2009 08:12:41 +0200 http://forum.wiibrew.org/read.php?25,18521,20347#msg-20347 Re: BackupMii: What means "ECC Failure (Corrected)"?http://forum.wiibrew.org/read.php?25,18521,20347#msg-20347

Magnetic media reading and writing is not an exact process. It isn't a matter of a 1 or a 0, but a wide variance of signal anywhere between a clear 1 or 0.

Hard drives, as they get denser, produce hundreds of errors a minute that are corrected by Error Correcting Code, which make informed decisions based on the surrounding bits whether this muddled bit is a 1 or a 0.

Same thing happens, in a different way, with flash memory.

You could have looked it up on wikipedia.
Actually that is not true. It is ECC as in cryptography.]]> icefire BootMii BetaFri, 12 Jun 2009 07:28:31 +0200 http://forum.wiibrew.org/read.php?25,18521,19855#msg-19855 Re: BackupMii: What means "ECC Failure (Corrected)"?http://forum.wiibrew.org/read.php?25,18521,19855#msg-19855

I got that failure NOT in the installer.log, I got it while a NAND-Dump, between the BAD-Blocks....]]> boy2048 BootMii BetaSun, 31 May 2009 12:47:02 +0200 http://forum.wiibrew.org/read.php?25,18521,18521#msg-18521 BackupMii: What means "ECC Failure (Corrected)"?http://forum.wiibrew.org/read.php?25,18521,18521#msg-18521(Corrected).
