Aspects of a storage device are provided for handling GBBs with defects between global interconnects and local word lines. The storage device includes a plurality of blocks each including a plurality of word lines, a plurality of interconnects within an interconnect set and between multiple ones of the blocks, volatile memory, and a controller. The controller determines a logical address pattern associated with the multiple ones of the blocks respectively including a program failure, determines whether the logical address pattern is associated with the interconnect set for the multiple ones of the blocks, determines a common word line associated with the program failures in the multiple ones of the blocks, un-marks these blocks as GBBs, and refrains from programming the common word line during respective program operations in the multiple ones of the blocks. Thus, blocks may be reclaimed, defective word line(s) isolated, and likelihood of read-only modes reduced.
