A system includes a memory device storing groups of managed units and a processing device operatively coupled to the memory device. The processing device is to, during power on of the memory device, perform including: causing a read operation to be performed at a subset of a group of managed units; determining a bit error rate related to data read from the subset of the group of managed units; and in response to the bit error rate satisfying a threshold criterion, causing a rewrite of the data stored at the group of managed units.
