SCSI Error Codes

If there is an error condition on a SCSI drive which is built in or connected to the MultiPlayer, the player requests sense data from the drive and displays these data as a three digit hexadecimal number. The first digit is the "Sense Key", the following two digits are the "Additional Sense Code" (ASC). The "Additional Sense Code Qualifier" (ASCQ) is not displayed. Here is a short desciption of these error codes and their most likely reasons for appearance on the MultiPlayer.
A good location to obtain informations about Additional Sense Codes from is: http://www.t10.org/lists/2asc.htm
 
Sense Key Descriptions
Sense
Key
Description
0h NO SENSE
No specific sense key to be reported for the drive. Should not be produced here.
1h RECOVERED ERROR 
Last Command was completed succesfully with some error recovery action by the drive
2h NOT READY
The drive could not be accessed. Perhaps the medium of a removable disk drive is not inserted properly or the drive was not yet ready. Typically, CD-ROM drives need a few seconds after the medium has been inserted before they can access the data - try the aborted operation again! If this doesn't work, try to remove the medium from the drive, insert it again and wait a few seconds before making a new attempt to access the medium.
3h MEDIUM ERROR
The drive could not access data because there is probably a flaw in the medium or an error in the recorded data. In case of CD-ROM: Try to clean the surface of the CD-ROM. May also be that there is some dust on the lens inside the CD-ROM drive. In case of harddisk: try to format the medium - bad sectors will be mapped out by this operation.
4h HARDWARE ERROR
There was a non-recoverable hardware failure (e.g. device failure, parity error, etc.). Seems that this drive has been demaged.
5h ILLEGAL REQUEST
An illegal parameter was sent to the drive, e.g. a request to access a block of data beyond the end of the medium. This may occur if there are some wrong data within the system area (FAT or directory) caused by an error while accessing the medium. Probably caused by bad SCSI cable or wrong termination of the SCSI bus.
6h UNIT ATTENTION
A removable medium has been changed or the drive has been reset. Simply try the operation again.
7h DATA PROTECT
The data on the medium are protected from current operation. Perhaps the Write Protect Switch of your medium is ON?
8h BLANK CHECK
Blank medium or end of medium (read operations) or non-blank medium while writing to a write-once device.
9h Vendor Specific. At least the manufacturer of your SCSI-drive should know what this error means...
Ah COPY ABORTED
Not produced, since the MultiPlayer does not use any SCSI COPY or COMPARE command.
Bh ABORTED COMMAND
Try to start that operation again.
Ch EQUAL
Not produced, since the MultiPlayer does not use the SEARCH DATA command.
Dh VOLUME OVERFLOW
An operation which could cause this error is not supported by the MultiPlayer.
Eh MISCOMPARE
Not produced here.
