I recently pulled OEM 60 GB HD from Compaq Presario 2110US, and installed a new Toshiba 120 GB HD. I used the original Compaq CD for installing Windows XP SP1, then patiently worked through every *% update to get the entire SP2 and eternal fixes.
I set up the HD with NTFS or whatever the initials are, instead of FAT32. For some reason I am already getting a "low on disk space" message. I checked the hard drive size TWO different ways and it states the size is 10.1 GB.

"Help, my HD size is falling and it can't get back up!"

I checked the Microsoft site for the above error message and it suggested entering a "diskpart add" command in DOS, but that has changed nothing AND "the DOS SCREEN said something about "this is not a command" or some such malarkey.

I don't want to reformat the entire drive and then spend hours reinstalling XP Service Pack 2+Infinity.

A virus did not do this as I have been running checks with two programs and haven't installed much so far. Everything has come up clean.

Ideas, anyone?

I'm lost in the Windows Fog again" to paraphrase an old song.

thanks

It could be a bad drive. It should hopefully be under warrenty I would send it to the manufacture an see what they wouldnt do.1. Disk Management Utility. Use the disk management utility to view how that disk has been partitioned. Select Start -> Run -> type "diskmgmt.msc" and hit enter. Bottom half of window should show it as 'Drive 0". It probably shows over 100 GBytes of unallocated space. If this is true, the software provided by Microsoft will not let you make the existing system and/or boot volume(s) larger without reloading. You'd have to use third party software to do this.

The windows software will however permit you to create additional volumes out of the unallocated space.

How big does Disk Management think your "C:" drive is?

2. Compaq CD. Is this a "Recovery CD" which automatically restores your disk and software to the state it was delivered? Well, the jury considered all the evidence and determined that I failed the HD IQ test.

Thanks, dahlarbear, you were on the money with your reply.

The Disk Management Utility did show I also have a drive "E" which has 100 free GB and no formatting (neither NTFS nor FAT32). I kinda remember that when I set up this new HD (which is a Seagate, by the way), I formatted only a partial chunk of the 120 with NTFS. I guess that was the 10GB that now my system believes is running low.

Now the challenge is to lump these two together as one, under the NTFS. I will take on that challenge next.

THANKS AGAIN.You can resize your small partition to take advantage of all the unpartitioned space with a partition manager.
Gparted is a very powerful partition manager that also happens to be free.
Download the LiveCD version from here.
Burn it to a CD as an image. (Don't burn it as a regular data disc.)
Reboot the computer with the disc in the drive, GParted should start.

Remember to backup your data before using a partition manager. Although it shouldn't delete your data it is better to be safe than sorry.
