1628.2 CALCULATING THE VOLUME SERIAL NUMBER
17
18For example, say a disk was formatted on 26 Dec 95 at 9:55 PM and 41.94
19seconds. DOS takes the date and time just before it writes it to the
20disk.
21
22Low order word is calculated: Volume Serial Number is:
23 Month & Day 12/26 0c1ah
24 Sec & Hundrenths 41:94 295eh 3578:1d02
25 -----
26 3578h
27
28High order word is calculated:
29 Hours & Minutes 21:55 1537h
30 Year 1995 07cbh
