Windows 7: Hard drive evolution could hit Microsoft XP users

As I understand things in a non-technical way: the first storage media (for PC) was a 5 1/4" floppy (I still have quite a collection of them). It could store 512KB of data (in blocks of 512 bytes). Next the 3.5" Floppy, 1.4MB, but the data was still stored in blocks of 512 bytes. My first hard drive was 40MB and used the same blocks of 512 bytes to store data. With the much larger hard drives of today, this ancient file system wastes a lot of space.

I try to envision a hard drive as a room, a square room with no windows and one door. I could throw papers into the room until there was a pile in the center ... not very productive. I could stack papers from the floor to the ceiling, better use of space, but hard to find that one piece of paper when needed. So I fill the room with file cabinets and organize my papers by file drawer, and file folder. Very efficient for locating a specific piece of paper. However, a lot of room is taken up by the file cabinets themselves. And even if I had 20 file folders in one file drawer, if each folder only had one piece of paper in it, all the unused space in that drawer is wasted.

So it is a 1TB hard drive will have 930GB of available space after the file system is in place. And fragmented data will cause more space to be unavailable.

Western Digital reported it had developed a file system based on "4kb sectors" instead of the "512 byte sector" currently in use. The problem is that a new hard drive capable of understanding the new file system is required. Trying to put one of these new hard drives in an old OS (XP, 2K, 98) may cause problems. Once the market has sold out of the current hard drive types (both new and used), owners of older computers and older OSs may find it even more difficult to cling to their favorite, if not ancient software.

I found this thread from December here: WD format provides "free" 11% extra storage

Also reported in the article: "Hard drive makers have begun an education and awareness campaign..." I for one would like to know if they would care to make a presentation to the members of Windows Seven Forums? I would like to know how the new file format could impact Windows 7 users like myself.

Thanks. i just didn't see the name of it. 4K...not really eye grabbing.

True, compared to 1TB ie 1,000,000,000,000 B (bytes).

But compare 512 bytes to 4,000 bytes (4k) and that is a huge difference. As hard drives get larger, 2TB, 6TB, 10TB?, that will translate into a lot of NOT WASTED SPACE, a very good thing, and may even mean faster access of the data. Who doesn't want a faster computer?

I need to check my calender. Is it 2011 yet.

WD Caviar Green desktop and Scorpio Blue mobile drives are already shipping with 4KB sectors. It expects the rest to follow rapidly as new, more capacious models are introduced. ®

This is on the last line of this article which has a fix for XP supplied by WD.

WD targets Win XP users to ease 4KB drive upgrades ? Register Hardware
