RN102 6.4.2 Update: Previously formatted disk(s) detected (Dirty Disks) #26453094
Hi all,
I just recently upgraded to OS 6.4.2. After the install/upgrade, my RN is now saying in RAIDar:
"Previously formatted disk(s) detected (Dirty Disks)"
I'm not sure what else ...
You formatted this other drive using RAIDar? Or some other way and you still got corrupt root?
Support has responded to your case and provided instructions on what they need. You should power down the NAS, remove the disk you are experimenting with and put the disk with your data back in the NAS and follow their instructions.
They can then analyse what is going on.
Thanks mate,
Yeah double dipped shortly after posting here.
I've sent support what they need.
FYI: It was formatting via RAIDar.
Support has not yet received your agreement to our Remote Access Policy. They are waiting for this.
Support has identified that your disk has 64728 reallocated sectors and 8 current pending sectors and 300 ATA errors. This disk is clearly bad.
It is recommended to check for a failing disk before doing a firmware update. You should not do a firmware update if there is a bad disk in the system. This is mentioned in the guide I referred to earlier.If you need a data recovery attempt you may need to purchase a data recovery contract. It may be necessary to try cloning the disk using a tool designed to clone a failing disk e.g. dd_rescue
I upgraded at the weekend to 6.4.2 from 6.4.1. immediately afterwards the disk in drive 1 failed (on 102). i don't believe in co-incidences. both disks were healthy prior to the upgrade (cycle count 55, status new and all green with no email alerts re system degrade status), the system is now degraded with drive 1 not being recognized in spite of being removed and re-inserted (with power recycle).
both disks are 3 Tb WD red .... both bought at the same time and about 2 yrs old. logs are available. this sounds similiar to this issue. only using < 20% of capacity so not that either. running in RAID 1.
however as co-incidence would be unlikely, I suspect there is a problem with the upgrade process. I have downgraded to 6.4.1 with no success.
thoughts ?
