problem with a new HD

i bought an 80G western digital HD,(WD800J formatted it via a USB connector with a laptop.. it formatted "80G"

loaded XP pro+SP1, and started loading programs, somewhere down the way something clashed and i thought "it's still early, why not format and reinstall?"

when i connected the HD to the laptop, it formatted 74.5G

question, where did i lose 5.5G?

according to the WD site, the HD is:

Cylinders - 16383
Sectors per Track - 63
Bytes per Sector - 512

but according to the BIOS it's:
cylinders - 9729
head - 255
sector - 63
(landing zone 3808)

which is correct?

jonah "confused" jones

hopefully, XP Pro and possibly SP2

Hi Jonah: On my machine, the bios reports this for WD80 drive.

Cylinder 38309
Head 16
Precomp 0
Landing Zone 38308
Sector 255

Properties card says 74.5 GB capacity.
I'm not sure what all this means, but I thought it may be of some help to you.

Did you do the math, and remember that drive makers use a base 10 system for calculating capacity, but computers use a binary (base 2) system for the same thing, which leads to different results.

Base 10: 1GB = 1000MB
Base 2: 1GB = 1024MB

24MB decimal/binary difference X 80GB total advertised capacity = 1920MB "lost" before you even begin

So your 80GB drive has an unformatted capacity of about 78GB as far as the computer is concerned. The rest of the "missing" space is likely taken up by filesystem overhead. There's also the possibility of hidden partitions to store who knows what. Like those USB flash drives that come with that god awful U3 software. But to be honest, a formatted capacity of around 75GB for an 80GB drive doesn't seem out of the ordinary in any way.

For comparison, this is the Model No. WD800JB-00JJA0, of my drive.
Hope this is some help.

I found that when installing XP on the

In reply to: problem with a new HD

entire drive, and then like you, deciding to start over, I find that XP had created a partiton about 8 GB or so, thus the new install shows two placed to elect which partition to install on. Thus for the next install one must first delete the large partition and then the small one after that you get the option to install XP on the entire drive again. [seems that you can't simply delete the small one first to get the full dive back.

I went through this four times in the last three weeks on three different systems. [legal CD in all cases], Did reinstall just beause I deided to do things a little differently.

How to get back that lost space...

In reply to: problem with a new HD

Jonah, as the others have already said, you are going to lose that space the first time you partition and format your hard drive, but I have found a way to reclaim it. I used ?Acronis Disk Director Suite 10.0 (build 2.117)? to get it back. All I had to do was to right-click on the C:\ drive and increase its size by using the unallocated space that the partitioning and formatting created.

As for your sector size, when you got your first report, it showed the sectors at 512 bytes, but when you reformatted, I?ll bet it shows 4 KB for each sector. This will reduce the number of sectors per track, and also the amount of files you can squeeze on your hard drive. Using the Acronis Disk Director Suite 10.0 (build 2.117)?, you can solve that problem too.

If you are going to format the hard drive, within the format menu is an option for file formats, which you want set at NTFS, and there is also an option to set the sector size. By default, it will be set at 4 KB. You can change that to 512 bytes per sector from there.

If you have already formatted your hard drive and installed a few things, that?s no problem. From the same program, you can right-click on the drive letter and choose ?Advanced? and from that drop-down menu, choose ?Change Cluster Size?. I have never had any problem using this, but I would still recommend making a backup before you try this option?just in case?
