EEPROM Vendor Specific MODE SELECT Page -- Parameter Descriptions Data Type Binary Default 0080h Length (Bytes) 2 Usage Specifies the maximum amount of data to be transferred without disconnecting. This value is given in 512-byte increments. For example, a value of 8 indicates 4 KB. The drive rounds values that are not multiples of 8 down to the nearest multiple of 8. Minimum value of this field is 0000h, maximum value is FFFFh. When set to 1, limits fixed block MODE SELECT lengths to a multiple of 4 bytes. When set to 1, the drive reports a deferred recovered error as a current recovered error. Disables ejection of the cartridge at the completion of an unload operation initiated by a SCSI LOAD UNLOAD command. Sets the value of the allowed maximum marginal channel. When set to 1, the drive reports BUSY status if it is in the process of becoming ready. When set, the drive reports a UNIT ATTENTION when the EMAM data is available. When set to 1, the drive reports a recovered error if parity error retried successfully. Sets the default value of the PER bit of the Read / Write Error Recovery Mode Page (01h). Obsolete.

EEPROM Vendor Specific MODE SELECT Page -- Parameter Descriptions Data Type Binary Default 1 Length (Bytes) 1 Usage When set to 1, the drive rewinds the tape medium to BOT on reset. When set to 0, the drive does not rewind on reset. Caution: Partial block data may be written to tape if reset occurs during WRITE. Parameter Name RewindOnReset SageLoadCountThresh ASCII / Decimal 50 2 Sets the Load Count Tape Alert Warning Threshold to 100 times the input value; e. g. , 50 = 5, 000, 2 = 200, etc. When set to 1, data returned to the SCSI INQUIRY command complies with the SPC-2 specification. When set to 0, the data returned complies with X3. 131-1994 (SCSI-2). SCSI3Inq Binary 0 1 SCSI3Sense SCSIBusDMATimer Binary Decimal 1 2 1 1 Enables reporting of ASC/ASCQ values unique to SCSI-3. [. . . ] These commands do not cause the new image to become active. A Download Microcode and Save Mode WRITE BUFFER command must be issued for the image to become active. The drive must not contain any tape medium before starting an image download. This is to safeguard against accidentally starting a firmware update. [. . . ]
