Tip & How-To about Seagate 1 TB SATA II Hard Drive

Hard Drive Capacity NOT as Advertised

I found this excellent narrative at Tiger Direct of Canada. This is open information I just wanted to give credit for the method used by Tiger Direct to present this sometimes difficult to understand subject

  1. The way size is calculated and displayed.
  2. Any "Partitions" on the disk will change the total in a specific partition.
  3. Hidden files and folders decrease available space.
  4. Compression increases the apparent size, but not the physical size.
  5. Drives larger than the OS or Drivers natively supports.
First, the definition of a megabytes (or gigabytes) is a unit of data storage capacity measured in 1,048,576 bytes (or 1024KB). The larger the numbers, the more apparent the size difference will be when listing the size as megabytes (or gigabytes) versus bytes. Actually, both numbers are correct. The noticeable difference is due to the 1024KB definition of a megabyte. This is why a 95.3GB hard drive can also be listed as having 102 billion bytes of total space. Just think of it as "round off" In the screen shot at right: The first number is the total number of bytes, the second number is based on the number of megabytes or gigabytes.
Second, some computers have a non-DOS hard drive partition that is used for features such as Save to Disk, Hibernation, or Recovery. This partition is not normally reported by the operating system, although it can be viewed using a disk partition utility. This is very common on desktops and laptops. NOTE: Partition information will be created or formatted automatically during initial system setup and a system recovery.
Third, by default, all system files are hidden and cannot be seen. This may adversely affect the reporting of available hard drive space. You can set your Folder Options so you view system and hidden files and folders, but do be careful as changes to system files can adversely affect your system.
Fourth, if you turn on Compression for a drive, it will increase reported free space and used space, but since compression is based upon the actual contents, this number is not fixed, but will change as files are added or changed.
Fifth, older operating systems did not support some of today's larger drives, so the total space reported may be much smaller than the drive specifications.
It is also worth noting that bad sectors are corrected by your operating system and can change the total drive space, free space, or used space as well.
So as long as a drive is reporting a value approximately close to the specification value, you can be comfortable that you received the right drive and that you are getting to correct data storage. Of course, tuning of your drive's partitions and options can yield optimal values, but this is not something for the average user to explore.

Never had one and would not want one as the interest rate on them is sky high. Depends on who it is it may be a few 100% but can be 2,3,4000% so what looks good being able to get money quick you end up paying a lot more in the end. The only winners are them.

Won't allow me to use my gift card funds


In order to fix this problem, go to billing info, and when it lets you choose the credit card method, choose the option "none" then it will let you use your gift card. Otherwise it assumes you want to use a credit card. Hope this helps.
