Abstract:
Described embodiments detect an impending out-of-space (OOS) condition of a media. On startup, a media controller determines whether an impending OOS indicator is set from a previous startup. If the impending OOS indicator is not set, it is determined whether a free pool size has reached a threshold. The free pool is blocks of the solid-state media available to be written with data. If the free pool size has not reached the first threshold, while the startup time is less than a maximum startup time, garbage collection is performed on the solid-state media to accumulate blocks to the free pool. If the startup time reaches the maximum startup time and the free pool size has not reached the threshold, the impending OOS indicator is set and the media is operated in impending OOS mode. Otherwise, if the free pool size reaches the threshold, the media is operated in normal mode.
