Abstract
Technologies are described herein for temporarily writing data to a buffer zone on a recording medium of a storage device when the device is operating in a vibration condition. A vibration condition is detected in the storage device, and upon detecting the vibration condition, data of a current write operation is written to a buffer zone on a recording medium of the storage device, the buffer zone being configured with a lower areal density of storage than primary storage zones on the recording medium. At a later time, an idle condition may be detected in the device, and upon detecting the idle condition, it may be determined whether the vibration condition exists. If it is determined that the vibration condition no longer exists, the data is transferred from the buffer zone to the primary storage zones on the recording medium.
