Disk BIOS Error Codes
Table of error codes returned by the disk BIOS |
If DISKGURU encounters a problem, it displays the hexadecimal error
code returned by the disk BIOS. In the table below you can find
the explanation of some common error codes.
Code | Explanation |
01H | Invalid function or parameter |
02H | Address mark not found |
03H | Disk is write protected |
04H | Sector not found |
05H | Reset failed (hard disk) |
06H | Diskette has been changed |
07H | Drive parameter activity failed (hard disk) |
08H | DMA overrun |
09H | DMA attempted across 64K boundary |
0AH | Bad sector flag detected (hard disk) |
0BH | Bad track detected (hard disk) |
0CH | Unsupported track or invalid media |
0DH | Invalid number of sectors for Format (hard disk) |
0EH | Control data address mark detected (hard disk) |
0FH | DMA arbitration level out of range (hard disk) |
10H | Uncorrectable CRC or ECC error on read |
11H | ECC corrected data error (hard disk) |
20H | Disk controller failure |
31H | No media in drive |
32H | Drive does not support media type |
40H | Seek failed |
80H | Timeout (disk not ready) |
AAH | Drive not ready |
B0H | Volume not locked in drive (INT 13H Extensions) |
B1H | Volume locked in drive (INT 13H Extensions) |
B2H | Volume not removable (INT 13H Extensions) |
B3H | Volume in use (INT 13H Extensions) |
B4H | Lock count exceeded (INT 13H Extensions) |
B5H | Valid eject request failed (INT 13H Extensions) |
BBH | Undefined error (hard disk) |
CCH | Write fault (hard disk) |
E0H | Status register error (hard disk) |
FFH | Sense failed (hard disk) |
SP | Seek problem (hard disk) |
Actually, SP is not a BIOS error code. DISKGURU returns this code if it takes abnormally long time to locate a sector on a hard disk. It may indicate that the hard disk is becoming unstable. You should then consider backing up your important files!
