(g) Check if the write error count is less than SO in hexadecimal
notation (12S in decimal notation).
Remark The write error count changes greatly depending upon the
status of the work tape used.
Therefore, the above-
mentioned value is a reference value.
(h) Key in "A4". The tape is rewound up to BOT.
(i) Key in "BO". The MTU starts a read error test.
(j) After the completion of the read error test, the transfer block
count is indicated in hexadecimal notation to the display of SOD.
Therefore, check if it agrees with the transfer block count
obtained in the write error test.
(k) Key in "DSO". Then, the compare error count and parity error
count are indicated to the display of SOD. Check if both counts
are a each.
(1) Key in "B2", and "B3". Then, SENSE DATA 0, 1, and 2 are indicated
to the display of SOD. Check of this display is "Fa, 00, 4S".
Key in "B6", "B7", and "BS", and read the read error count (read
retry count).
(m) Check if the read error count is less than 1.
Remark The read error count changes greatly depending upon the
status of the work tape used. Therefore, the
above-mentioned value is only a reference value.
