Subject: Chances of silent errors?
Date: Mon, 21 Jan 2013 20:58:07 +0100 (CET) [thread overview]
Message-ID: <28222077.12.1358798287217.JavaMail.root@zimbra> (raw)
Hi all
Coming from the zfs world, I've heard a few talk about the chances of "silent errors", meaning the checksum on the drives match, but the data being bad because of matching checksum (aka collisions). Does anyone in here know the relative chance of something like that happening with the checksums of current harddisks? Is the 1:10^14 or 1:10^15 chances for a URE in regard to this, or is that when the drive reports an error, or those two combined?
Vennlige hilsener / Best regards
roy

I all pedagogikk er det essensielt at pensum presenteres intelligibelt. Det er et elementært imperativ for alle pedagoger å unngå eksessiv anvendelse av idiomer med xenotyp etymologi. I de fleste tilfeller eksisterer adekvate og relevante synonymer på norsk.
