what are my mistakes here?
given the following specification,
Bfr = (1024-100)/160= flore (5.775)= 5
Record per sector = 512/160 = floor(3.2)=3
Records per track = 3*50=150
Size in bytes = 150*160= 24,000 bytes
Track capacity = 24,000 /block capacity =24,000/1024 =
floor (23.4375)=23
Records per track = records per sector * number of sectors in
track -> 3*50=150
150* tracks per cylinder = 150*8= 1,200 records
Un used space in one sector = 512-(160*3)= 32 bytes
Un used space in 1 track = 32*50= 1,600 bytes
Un used space in 1 cylinder = 1600*8=12,800 bytes
