Introduction and General Information 21
Using CD-ROMs, DATs, Tapes, etc.
A SCSI device that is not a SCSI hard disk drive or a removable hard disk drive, or that does not
behave like one, is called a Non-Direct Access Device. Such a device is not configured with
StorCon and does not become a logical drive or host drive. SCSI devices of this kind are either
operated through the Advanced SCSI programming Interface (ASPI) (MS-DOS
†
, Windows, Novell
NetWare
†
or OS/2
†
), or are directly accessed from the operating system (UNIX
†
, Windows NT
†
).

NOTE
Hard disks and removable hard disks are called Direct Access Devices. However, there are some
Non-Direct Access Devices, for example, certain MO drive that can be operated just like removable
hard disks if they have been appropriately configured (for example, by changing their jumper
settings).
