- TITLE :Fujitsu M2511A Doesn't Recognize Disk Change
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:
-
- ----------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT operating system version 3.1
- - Microsoft Windows NT Advanced Server version 3.1
- ----------------------------------------------------------------------
-
- SYMPTOMS
- ========
-
- Windows NT fails to recognize a disk change in Fujitsu M2511A Magneto
- Optical disk drive. The directory displayed is the same as the previous
- disk.
-
- CAUSE
- =====
-
- The disk drive is shipped with incorrect settings for proper operation with
- Windows NT. The default settings do not recognize the Unit Attention signal
- which is generated when an error or disk change occurs. The system ignores
- this event and does not recognize disk changes.
-
- RESOLUTION
- ==========
-
- To allow the drive to operate correctly the drive switches must be
- configured as follows:
-
- There are two switch blocks, SW1 and SW2. SW1 has four switches and SW2 has
- eight. SW2-3 and SW2-5 must be on and SW2-7 must be off in order for
- Windows NT to recognize disk changes. In addition, the disk must be
- partitioned with Disk Administrator as type FAT.
-
