  • Page 95: Appendix A. Additional Information

    Diskette drives and diskettes are identified by their storage capacity (for example, 1.44MB diskette drive; 2MB diskette). The Model L40 SX operates with a 1.44MB diskette drive. This drive uses 1MB or 2MB 3.5-inch diskettes. Other IBM computers may operate with 720KB diskette drives that use only 1 MB 3.5-inch diskettes.
  • Page 96: Identifying Diskettes

    Identifying Diskettes A 1MB diskette looks like this: It is usually labeled 1.0MB capacity or 2DD and has a square cutout A 2MB diskette looks like this: It has the letters HD is usually labeled 2.0MB capacity and has two square cutouts Formatting Diskettes A diskette must be formatted to prepare it for use.
  • Page 97: Write-Protecting Diskettes

    Write-Protecting Diskettes It is possible to format a diskette or write (record) information onto a diskette unintentionally. Important information could be lost. For this reason, you should write-protect important diskettes. Some diskettes like the Reference Diskette are permanently write protected. When diskettes are write protected, you can read from the diskettes, but you cannot write onto them.
  • Page 98: The Ibm Disk Cache

    The IBM Disk Cache Technical Information IBMCACHE.SYS is a device driver that allows a portion of the computer memory to be used as a fixed disk cache (see the DOS manual for information about device drivers and the Buffers command). It can speed up application programs by keeping in the cache fixed disk data that is accessed repeatedly.
