Windows 7: Unformatable Unallocated Space

LOL - what I meant was - most intel storage controllers don't support disks that size.

Probably others don't normally either.

Therefore - whatever storage conbtroller you have - might be intel , might be something else - could be the issue.

Ther may be an update for whatever you are using from the mobo website.

Paragon make an app, to overcome it - but you can't use it to boot from if you do that.

Whay I think we are saying is that a bios update may resolve the problem if Asus decided to address it. If that is not the case, try to devide the partitions into 2 1,5 TB partitions or 3 partitions max. I have no reason to doubt Kado. He is saying to limit partitions to 3. Also no partition can be more than 2TB (less is better) the last partition must begin before the 2 TB mark on your drive. Correct me if I am wrong Kado.

You can have 4 partitions with mbr but usually one of those is the 200Mb system partition. Otherwise what you said is correct I beleive.

I don't think the dividing partitions thing will work for mbr style.

You will need to use gpt style.

Did you have the whole drive usable before?

You still didn't say what the error message is when you try and create a partition with Disk Management.

mmmm well i should prob state that the computer is a new build i havent listed yet

coolermaster cm690 -case
coolermaster gx750 - power supply
gigabyte GA-880GMA-UD2H Motherboard
sapphire hd5850 -graphics card
amd phenom x2 965 -cpu
kingston ddr3 1333 mhz -ram
asus blu ray writer
wd 3tb sata 3 hard drive

so the problem is even if its just out of the anti static bag i got the hard drive in if i run the windows 7 install instantly as soon as i got to the partition screen of the windows 7 it will partition it automaticly and make one partition 1.99 tb and the other 750 gigabyte

i go to make the 750 gig part of it allocated space and i get an error message 0x80042468

i have converted the drive to gpt no difference so im guessing it is as said the sata controller can not read more than 2 tb so im anal raped i guess until i get a newer motherboard that supports 3 tb drives

SIW- could you create 2 i.5TB primary partitions and format them before installation so that windows does not create the 100MB sys reserved partition?

I think what you may need to do is shrink the 1.99 Tb partition to get the start address for the rest below 2Tb.

Big drives like that are an additional complication to use. Not too bad if you juat want it for storage - more so if you want to boot from it.

I suggest home users are better using drives up to 2tb - saves a lot of hassle.

The beginning of the partitions are given in absolute values. So 2TiB is the combined size when using mbr.
