Dear All,
Last month we have had problem with our Terastation TS-4TL/5 , suddently our HD on ARRAY5 of us got error, below the description from log:

Jan 7 10:34:46 TS-XLC11 errormon[1563]: Error situation cleared! HD4 Error E23HD4 Is Faulty
Harddisk 01 of our Array5 had error with the red alert on the indicator lamp, and we had red alert on display said "RAID ERROR E13Array1 Error" but we still can access share data folder on it and so with the web interface access.
Last week we have replaced error harddisk with replacement HD and we have rebuild again, after the machine reeboot we have found new error that HD03 is faulty (red lamp indicator on HD).

Then we have pull out and inserted back HD in to the rack and the indicator lamp back to normal, but after it was all done the storage display show different alert " errormon[1530]: Error situation detected! RAID ARRAY1 E14Can't Mount"
- since that time we can't access shared folder .
- We can't perform disk check from Admin Interface.
- ARRAY1 of RAID5 error showed in the Admin Interface
- we had upgrade firmware, into 1.58 version but it seems not solved the problem.
Question:
- How does this happen?
- Is it any possiblility to save the data from the NAS storage?
Please help ASAP.
Thanks and Regards,
Pancayadi
If you need the data then contact a data recovery company however to be fair you should always have a backup. To get the unit operational again you will need to completely delete and recreate the RAID. This will erase all the data on the Terastation.
