With increasing sales of microcomputers having built in floppy-disk drives (FDDs), HDDs that would fit to the FDD mountings became desirable. Modern HDDs, such as SAS[84] and SATA[85] drives, appear at their interfaces as a contiguous set of logical blocks that are typically 512 bytes long, though the industry is in the Also, older operating systems such as Windows XP/2000 may not automatically recognize the new hard disk if the hardware is newer than the operating system. The first IBM drive, the 350 RAMAC in 1956, was approximately the size of two medium-sized refrigerators and stored five million six-bit characters (3.75 megabytes)[12] on a stack of 50 disks.[26]
