WD20EARS was got to be back up drive copied file on to drive was second drive not boot or raid.
Failed and lost all data send back got replacement second drive failed lost data for second time
Multi-Zone Error Rate count trying to recover some data very slow read
But WD says drive not in warrantee they have not accepted drive was returned even though I opted for replacement to be sent out only when old received by WD and have email to confirm arrived
Question Is this normal behaviour for WD and are WD drives any use at all for back up ??
And if so what model
Understand that there is no other cost effective method to back up the data than a hard drive
Thanks for any assistance John
