Solved!

HP G62-234DX hard drive

HP Recommended

Hello, I recently purchased an HP G62-234DX laptop from Best Buy that was on sale last week. The information can be found here: http://www.bestbuy.com/site/HP+-+Laptop+/+Intel%26%23174%3B+Core%26%23153%3B+i3+Processor+/+15.6%22+...

 

The store I went to ran out of stock on this model, but I was able to pay for one and have it shipped over from another store. I picked it up today and everything seems fine. I only have one question, the information on Best Buy's website says the laptop has a 250GB hard drive, but do I really have 250GB: http://img832.imageshack.us/img832/1408/8347292.png

 

 

Thanks

A couple of reasons it is smaller.

 

There are 4 partitions on the hard drive that take up space, use Disk Management to see all of them and how much disk space they take up.

 

When you format a drive in Windows you will lose 7% of the drive space, then add this to the amount the other 3 partitions use and you have what is left for C: partition.

 

So you lose 17.5 GB in formatting alone.

 

The loss is due to a discrepancy in the math used to format a drive and what hard drive manufacturers say a GB, MB, KB equals, and there is other disk space overhead that goes with formatting for a file system.

 

Manufacturers sell the drive based on 1GB=1000MB, 1MB=1000kb 1KB=1000bytes, etc.

Hard drives are formatted like this: 1GB=1024MB, 1MB=1024kb, 1KB=1024bytes, etc.

OK, this is an old story... to put in simple words, Hard Drive manufactures and Windows measure the size on different scale...

To get little more technical...Here is the math...

Hard drive manufacturers calculate hard disk size in 'base 10' notation while Windows does the calculation in 'base 2' format....

base 2 of 10 is 1024 is 1 kilobyte
base 2 of 20 is 1048576 or 1 megabyte
base 2 of 30 is 1073741824 or 1 gigabyte

So when the hard disk manufacturer says 250 GB hard drive, that equals 250,000,000,000 bytes. Now windows divides this number by what it considers a GB (1073741824) and reports the hard disk size as:

250000000000 (bytes) / 1073741824 (bytes per GB) = 232.8 GB

So now let us add all the partition up on your laptop....0.1 MB (System Partition) + 218 GB (OS Partition) + 14.2 GB (Recovery Partition) + 0.1 MB (HP Tools Partition) = 232.4 GB

This information is there a one of the label on the box itself...
