32769? 2 surfaces per platter plus one for timing? OK. Is There a taboo against using surface 0000? Depends on how thick the platters are. You forgot the smiley. Well, if IBM's new DASD architecture were manufactured in the same manner as previous DASD devices, you would have 278,921,216 tracks on each surface. What diameter do you think such platters would be? How long would it take the access arm to traverse the radius? -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
