In recent weeks we have been receiving extremely high volumes of failed LaCie NAS devices with the following hard drives:
Seagate 1.5TB SATA drive
Model number ST31500341AS
In many cases, all the hard drives appear to be developing bad sectors. We recommend you monitor your LaCie carefully. If you know you have these drives installed, please ensure your data is backed up onto another device. Do not treat LaCie or any NAS device as backup.
