Western Digital NAS Problems

We have recently started to see a peak in the number of 500GB WD drives sent to us from Western Digital MyBook World edition NAS Servers. These NAS devices use two WD5000AAKS drives in a RAID configuration.

The worrying thing for users is that even drives used in RAID 1 mirror mode are having problems, where either both drives are failing at the same time or where one drive has failed in the past and the other following suit some time later.

It is an important reminder that RAID does not equal backup. If there is important data on these types of devices, it also needs to be copied to another device for peace of mind.

We are currently able to recover the data from these devices using a combination of firmware repairs and other recovery methods.

An interesting note is that we have also seen a small increase in other WD drives at the moment, such as the 320GB WD3200AAJS drives from iMacs and WD5000AACS drives from external enclosures.

More to come I’m sure…
