538905 2007-04-08 02:12:00 I have just installed a 160BG internal hardrive which appears as 149.05 GB after formatting. Is that what I should see? If so why is it called 160GB? bpt2 (6653)

538907 2007-04-08 02:32:00 Here's a formula to convert retail size to actual size. This assumes that the manufacturer is using 1GB = 1,000,000,000 bytes (instead of 1GB = 1,073,741,824 bytes as they should).

Actual Drive Size = Retail Drive Size * 0.931

This formula is an approximation. Many times they'll round the drive size somewhat, but this gives you a rough idea of the real world space.

For Quick Reference:

36gb = 33.5gb

40gb = 37gb

60gb = 55gb

74gb = 69gb

80gb = 74gb

100gb = 93gb

120gb = 112gb

160gb = 149gb

200gb = 186gb

250gb = 233gb

300gb = 279gb

350gb = 326gb

400gb = 372gb

500gb = 465gb

These are rounded to the nearest gigabyte.

538908 2007-04-08 02:37:00 Hard drive manufactures measure 1GB as 1000MB whereas the operating system measures 1GB as 1024MB. It still confuses me a little so check out wikipedia (en.wikipedia.org). Plus theres a little overhead when the drive is partitioned, etc. sal (67)
538909 2007-04-08 05:05:00 I think its called using the Decimal system instead of the Binary System. GB instead of GiB jamesyboi (6579)
