Remember that harddisk manufacturers use 1GB=10^9 = 1000000000 bytes (which is arguably the correct definition) while most OS's use 1GB = 2^30 = 1073741824 bytes. This probably accounts for the difference. So there is not really any problem, it is just that the gigabytes that the manufacturer claims the disk has are not the same size as the gigabytes that the OS claims to see. > > is there a way arounf it? > > some additional data are: > > model: IC35L060AVV207-0 > LBA: 120.103.200 sectors According to this the disk has 120103200 sectors, each of which is 512 bytes. This gives a total size of 61492838400 bytes. Divide this by 10^9 and you get 61.49 GB Divide it by 2^30 and you get 57.27 GB Those are probably the numbers you are getting, and if so everything should be OK. > CHS: 16383/16/63 > > i am using an ASUS CUL2 m/b > -- Erik Trulsson ertr1013@student.uu.se _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org"
