Your harddisk is 60 marketing GB (see below).

7476*16065*512/1024 = 60050970 KB = 58643.525 MB = 57.269 GB (factor 1024)

489951 KB + 59560987 KB = 60050938 KB (see above, the + indicates a small
loss).

59560987 KB = 58165.026 MB = 56.802 GB (factor 1024)

PE Size = 4 MB

> Total PE              14541

14541*4 MB = 58164 MB = 56.800 GB = 59559936 KB (factor 1024)

59560987 KB - 59559936 KB = 1051 KB = 1.026 MB ( < 4MB, so no additional PE
is possible).

Don't believe in the disksizes of marketing guys. These guys only know
calculations with 1000 :-)
