Symptom: The latest 3 1/2-inch Drive mechanism part number 09114-69511 date
codes 2513 and 2514, when in products with the older E-PROM, part number
09122-15512 and earlier, does not perform the jumper-initiated Format Test
correctly.
Due to timing differences between the new drive and controllers with older
firmware, step commands may riot all be performed by the drive during the
Service Format Test. When this occurs, all tracks will not be formatted. The
test will not indicate a failure as no read operation ;s done during the test.
A failure will not occu~ until an read or write operation is attempted. The
failure occurs on the jumoer-initiated Format Tests (Tests 12 and 13) ONLY.
No other tests or functions are effected.
Solution: The New E-PROM, part n~mber 09122-15513, corrects timing problems
for both the earlier and later drives. The Controller/Power PCA, part number
09122-69501 date code 2513 and later has the new E-PROM.
