HDAT2 forum

Hi all, please help, I search for a night without sleep and finally find this HDAT2.

My hard disk is 80GB. Now it is 75GB.
The story is
I installed acronis true image and set a secure zone ( I remember I have ) , it's about 4.xx gb size. After that, I just format my hard disk and install window xp again without uninstalling the acronis true image ( I didn't know I have to uninstall the acronis true image to release the secure zone.)

The problem happens, when I reformat the PC, only 75.xx GB remain. After installing Windows xp , the system shows only 75.xxGB . ( I have use partition magic, acronis disk director server to check, same result), there are no hidden area, no un assigned area.

What can I do now? I want that 4.xxGB back.

I have tried using HDAT2 following your guide, went into SET MAX (HPA) menu, set the Natural Maximum area, but now work.

Can you explain step by step what I should do ?

Maybe it's not HPA but a regular hidden partition.
If you don't need the data try to 0-fill the drive.

thks, spildit,
Could you teach me how to do that?

Hi,

it seems you have a hidden partition on hard disk.

If you are using Windows:

Click Start, click Run, type compmgmt.msc, and then click OK.
You should see a system partition C: and, maybe, another partition ...
You can try to remove it (if possible) or manually with any disk editor
as dskprobe.exe (see my document http://www.hdat2.com/files/disk_probe.pdf).
The procedure is not intended for this case but you can try to remove
this (potential) hidden partition.

If you can make a screen shot from Disk Management, please.

I have a fujitsu hard drive. When I boot Bios detects the hard disk but it cannot access it. In the setup screen in CMOS I try the autodetect feature, it again detects the hard drive but cannot read its size. The Bios detects the Hard disk's name but the name isn't really correct. BTW that is my primary hard drive, I have another slave hard drive which is detected. They are IDE hard drives. Now to return to my problem it detects the name of the hard drive something like this Fujitsu MPR3XXX etc. The XXX before were really some numbers. Is this hard drive dead? I again reinstalled Windows to the secondary hard disk and windows setup says that this hard disk cannot be accessed. What should I do?

Hi,

it seems the firmware of HDD is corrupt.
You need a help from any profi at your location or make a RMA (make a claim).
