just bought the drive a few minutes ago. plugged in and installed. checked my computer and shows it has just 930GB. why is that? i have a pasport 160GB as well but only was missing a few gigs when installed. this drive is missing 70GB!
That’s about right. 1TB drive will have 930 actual GB’s.
I found this out from WD’s knowledge base. It’s kb 615 if you’re interested.
I have just answered the same question for a 500GB drive :
Unfortunately, manufacturers use "commercial" storage capacity instead of real storage capacity. Let me try to explain this. Technically, all data in computers is binary : 1KB = 1,024 B 1MB = 1,024 KB = 1,048,576 B 1GB = 1,024 MB = 1,048,576 KB = 1,073,741,824 B Commercially : 1 GB = 1,000 MB = 1,000,000 KB = 1,000,000,000 B So when a HD drive manufacturer says 500GB, they mean 500,000,000,000 B 500,000,000,000 / 1024 / 1024 / 1024 = 465GB This explains why you see 465GB. Hope I didn't loose you there. You can't blame WD for using "commercial" storage capacity, all other manufacturers do and they have to follow.
Hope this helps ;)
