For certain SIM reference codes, the last 13 bits of a reference code (in binary) can be converted to the number of the drive box and drive where the error occurred.

  1. Convert the last 13 bits of a reference code from binary to decimal.
    For example, the last 13 bits of eb75a5 (in hexadecimal) is 1010110100101 (in binary), which can be converted to 5,541 (in decimal).
  2. Divide the number obtained in step 1 by 32.
    For example, 5,541 / 32 = 173 (quotient) with a remainder of 5.
  3. Divide the quotient obtained in step 2 by 2. The obtained quotient is the drive box number.
    For example, 173 / 2 = 86 (quotient) with a remainder of 1. Therefore, the drive box number is 86 (DB-86).
  4. The drive number can be obtained by the following equation:
    Drive number = remainder-obtained-in-step3 x 12 + remainder-obtained-in-step2
    For example, if the reference code is eb75a5 (in hexadecimal):
    Drive number = 1 x 12 + 5 = 17
    Therefore, the drive number is 17 (HDD86-17).
