Machines AFFECTED

PHYSICAL check:
Only Diskette Drives "manufactured for IBM corporation," with a "YD" as the first characters of the top line of print on the identification label, and a revision code of C01, C02 and C03 are affected by this problem.

The affected drives may be identified by referring to the last number in the bottom line of print of the label identified in the following diagram:

DETAIL:
Under certain conditions, the head leadscrew assembly may bind, causing Diskette Drive errors.

After Power-on, or warm boot, if the machine shows 162 and 601 errors, check the Diskette Drive for the conditions listed under "physical check" above.

Only revision levels C01, C02 and C03 are affected by this condition. All other levels of Diskette Drives manufactured for IBM are unaffected and therefore, not eligible for this ECA:.
