GE Healthcare CT error code, reported by the GE LightSpeed CT platform.
What 3604506 means
On LightSpeed QX/i and LightSpeed Ultra and LightSpeed Plus CT systems, status code 3604506 indicates: SCSI sense-data error 3604506 (S_scsiLib_UNKNOWN_SENSE_DATA). The code originates in the Scan Data Disk (SCSI) section of the GE LightSpeed CT platform. Severity level error (Error condition).
Reported action: Treat this as a SCSI sense-data fault pointing at the scan-data disk or its cable, not a software glitch — the source explicitly suspects the disk or cable is bad. Check the scan-data-disk chain (disk, cables, SCSI control board) first; in the case documented here, replacing the raw-data disk and clearing the recon queue cleared it..
An errnoGet() value seen in the iceConsole log during a scan-stopping SCSI scan-data-disk fault on LightSpeed QX/i, Ultra and Plus systems. The source identifies it precisely as S_scsiLib_UNKNOWN_SENSE_DATA in scsiLib.h — an unrecognized SCSI sense-data response from a query of the disk unit.
