Hello everyone,
Using a Pent4 2g PC using XP pro as OS.
I have just installed a new 160g hdd but it only shows as 76g.
I am sure I have seen similar postings but cannot recall the reason or solution.
Any suggestions please.

May be your BIOS will not allow your PC to see arge drives.

or
Do you have SP2 installed?

In Windows, click on Start->Run, enter "regedit".
# Navigate to the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\atapi\Parameters registry subkey.
# From the Edit menu, select New, DWORD Value.
# Enter the name EnableBigLba, then press Enter.
# Double-click the new value, set it to 1, then click OK.
# Close the registry editor.
# Restart the machine for the change to take effect.

Thanks Fruit Bat,
I used to have 2 120g hdds which worked OK, does that tell me if BIOS supports large drives?

I do have SP2 installed, should I still edit the registry?

SP2 should already have the registry entry but is worth a check.

127G is usually the limit that windows shys at untill the EnableBigLba is set.

If the BIOS supported 120 drives then it should be ok for the 300, when you boot ut what does it show on the first screen as it displys all the devices?

300 read 160

has your drive been partition in two 80G each?
after formating these will read approx 76G

Bios says
Secondary IDE Master ST3160022ACE
Max capacity 160Gb.

I had better mention something here, to copy my stuff from the other drive I used "Paragon Drive Copy"

New drive appears as 76.3g exactly the same size as the (80g) I copied from.

*New drive appears as 76.3g exactly the same size as the (80g) I copied from.*

That'll probably be why then. have a look at the Paragon options, to see if it allows you to change the drive size when copying - some programs do - some don't.

If you go into Disk Management, you should see the other chunk showing as unallocated space. You can set it up from there as a secod drive if you wish - or you could use a different program to incorporate the spare space into the main volume - but be careful in case it goes wrong and you lose what you do have.

I though from the Paragon program that it would do this "Use this option if you want to install a larger drive" or words to that effect.
In drive management the rest of the drive shows as unallocated, what I want to do is make it one unpartitioned drive but I don`t know how.
It does not matter if I lose the data on it as I have
copies and can put that back later.

Can I reformat the drive and get it to appear as 160
I can sort the other stuff later or is this not the way to go.

*Can I reformat the drive and get it to appear as 160*

You can do it all from within Disk Management. Delete the existing partion, and remake it as a single one.
