Missing Hard Drive Gigs

  Newuser3605 20:43 28 Nov 2009

I bought a 500 GB IDE Hardrive which shows up as
Belarc 137 and
Everest 127
and on My Computer as 127

Have I done something wrong?
Apart from that it works fine.

Re-format the Drive to NTFS.

Shows 137G not 160G or Higher
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.

This is usually cured if you have SP2 installed

bowing to your superior knowledge, I hope I have not given wrong advice ??

Windows should see all of (465G) the 500 G dive whether FAT or NTFS
Even Win98 should be able to use the same reg hack to enable Large Block Array.

Another limitation could be the BIOS if its a very old machine but using drive overlays can get round that.

Many thanks for all the advice.
I followed Fruitbat's regedit suggestion which resulted in Everest saying that I had 465 Gb but the rest, including Defragmenter said about 127. It also says the file system is nfts.

I don't have SP2 so this might be the problem.
The computer is fairly up to date.

I checked the Helproom for other Missing Gigs postings and there was someone from a year ago with exactly the same problem.
He solved it, he says, by downloading Easeus, a free programme.
I have just downloaded it and it shows
Unallocated 333.77 Unused Logical
apart from the C drive.

I might give it a try at sorting things once I can work it out.
Thanks again.

You said you did not have SP2 - are you talking XP or Vista.

XP needed SP1A to see more than 127GB.

As you have formatted and installed from a XP disc pre Sp2 it could only see 127G so only formatted 127 of your 500 G drive.

All you need to do is go in to disk management (right click My computer - Manage - Storage _ disk management) click on the unallocated part of the drive and format it. Assign a drive letter and then it will be available as a separate drive to store your data or programs on.

Many thanks Fruitbat.
I went there and clicked everything and it ended up as 'free space' with no indication of how to format it and allocate a drive letter to it.
