Dale, you're not reading my posts. ;-) I answered that in the email below to which you replied. > You'll never get 250gb out of it, but you certainly should get >quite a bit more than 127-137gb; assuming your OS, file system, >and motherboard's BIOS support the 250gb drive size
I'll try this again. Even if you have an mobo, BIOS, and OS that will support a single partitioned HD that's 250gb in size, it will never show that amount under "My computer" or anywhere else you see the HD listed in Windows due to the differences in drive labeling in DOS bytes as compared to bytes in Windows, and formatting. I think you mentioned it's now showing 240gb in Windows, and I said that's probably about right. I said yesterday that I THINK it's 1008 bytes DOS = 1000 bytes in Windows, but like Steve said, he thinks it's 1024 bytes which it may be. I had "8" stuck in my head from converting Kbits/sec and KBytes/sec in transfer speeds for modems. (8 bits = 1 byte). Ultra ATA isn't going to change anything. There was "ultra" ATA since UDMA33. They are all considered "ultra". They were once called UDMA33, UDMA66, UDMA100 and UDMA133, but the "UDMA" was replaced with "ATA". The "U" in "UDMA" stands for "Ultra", and the "DMA" is Direct Memory Access. The suffix numbers indicate the maximum burst transfer speeds in MB/sec. Ok, I found this. http://www.smartftp.com/support/kb/index.php/53 You can see the area about 8 bits equaling 1 byte, and the 1024 bytes equaling 1KB, or 1000 bytes in Windows. "How many bytes are in a kilobyte (KB)? One may think it's 1000 bytes, but its really 1024. Why is this so? It turns out that our early computer engineers [who used DOS], who dealt with the tiniest amounts of storage, noticed that 2^10 (1024) was very close to 10^3 (1000); so based on the prefix kilo, for 1000, they created the KB. (You may have heard of kilometers (Km) which is 1000 meters). So in actuality, one KB is really 1024 bytes, not 1000. It's a small difference, but it adds up over a while." I think this works out to about 244gb for your 250gb HD. So 240gb may be about right after formatting. -Clint God Bless Clint Hamilton, Owner http://OrpheusComputing.com ) ----- Original Message ----- From: <[EMAIL PROTECTED]> In a message dated 8/20/2004 6:36:29 AM Eastern Daylight Time, orpheuscomputing.com writes: > You'll never get 250gb out of it, but you certainly should get quite a bit > more than 127-137gb; assuming your OS, file system, and motherboard's BIOS > support the 250gb drive size Then, what's the point of my buying (or WD even making) a 250 if I'm only going to get 137 out of it? According to the papers that came with it, I'll probably need an Ultra ATA to get use of the full 250, but I have no idea if the mobo will support it. If not, I guess I got screwed again.
