I seem to have had a run of bad luck with one of my suppliers of late.
Suddenly I’m receiving a lot of Routerboards (411’s and 433’s) with bad blocks in System - Resources - General.
How can I get rid of the bad blocks?
Thanks
how many? 1-2 bads is normal. >100 is bad %)
I’m seeing 3-4 but the hardware does strange things like drop connections when it hits the bad blocks.
what is bad blocks ? i can’t find it on System - Resources - General
System->resources
or
/system resource print

you see, i don’t have any bad blocks
Good for you!
Doesn’t solve my problem though.
As previously said, under 100 bad blocks is normal. The problems that could arise with more blocks are not related to connection issues. That’s completely unrelated.
Normis,
As you know, we’ve been having problems out here with RB600’s that reset themselves as soon as we put heavy traffic through the wireless cards and RB433AHs that reset themselves as soon as we put heavy traffic through the ethernet ports. The logs say the machines have been rebooted due to a power failure. The “reboot” only takes 3 - 4 seconds. There’s no way an RB600 can reboot in that time.
Well here’s the thing. When there are zero bad blocks on the RB600 or the RB433AH and doesn’t happen. If there are bad blocks (even 3 or 4) on the RB, it misbehaves - even when running ver 4.4. I was up till 3:00am testing and hoping that the new version would have resolved this problem.
What do I do?
as normis said - these problems are not related. that is, as far as i know.
What is heavy load? How much traffic, with what configuration? Or there is low traffic with some fancy firewall rules?
this is print out of my test RB600 that is working, load is not very high at the moment

make supout.rif file immediately after such reboot and send to support
We did that many days ago and were told that the problem was related to electrical supply. We changed power supplies. Problem still there. We went from PoE direct to power being supplied via the power jack and the problem persisted. It was only when we replaced the test site board with one that had zero bad blocks that the problem went away.
Did you check if capacitors are in good shape?
That’s a good point.
But since we’re talking brand new equipment here, that would refer back to my very first post of
