When a device is detached and taken offline for firmware updates, etc., the remaining I/O requests are regarded as successful without being resubmitted, causing data corruption. Raw kernel: sd 8:0:1:4: rejecting I/O to offline device kernel: sd 8:0:1:3: rejecting I/O to offline devic...
we created a molecular digital data storage system called “DNA Mutational Overwriting Storage” (DMOS) that stores information by leveraging combinatorial, addressable, orthogonal, and independent in vitro CRISPR base-editing reactions to write data on a blank pool of greenly synthesized DNA tapes. As...
