769228 2009-04-28 10:53:00 Hi All

Bought a 250gb Western Digital Hdd and installed it. Only shows 127gb. In Comp. Management / Disk Management it shows as 127 gb, NTFS and 104gb as unallocated. Am running XP with 2gb ram, plus Service packs two and three. Would like to have one large partition rather than two. Have tried a couple of suggstions I found on Press F1 but no joy. They date back to about 2004.
Anyone got any later ideas?

Cheers:

769229 2009-04-28 11:01:00 Does the BIOS see ALL of the hdd?? How old is the system?? Is it old or new?? If its pretty recent, go to control panel / admin tools / computer management / disk management. Action menu / rescan disks. Does it show the whole hdd now?

Have you installed all of the drivers, including the chipset drivers, if you installed XP recently? The 104gb unallocated sounds like it needs to be formatted, highlight it / right mouse / format / initialize

I would use more than 1 partition, in case something screws the one partition up. Then you'll have to start all over again (and it'll take longer to format)

Plus Service packs two and three

769233 2009-04-28 11:48:00 Plus Service packs two and threeYes, but was the installation done with a pre-service pack version of XP? Installing the service packs later does not overcome the 127 gig limitation that the XP original had.

I take it the 250 gig drive was used to install the OS on and it is not a slave drive?

769234 2009-04-28 22:48:00 You might need to enable 48-bit LBA. Google will show you how utopian201 (6245)
769235 2009-04-29 07:28:00 enable bigLBA
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\atapi\Parameters
create a double word variable called EnableBigLba and set it to 1
reboot and repartition your hard disk

had to do this on my "TVPC" video server hard disk (465gig) which has 2k sp4 on a seperate 6 gig Hdd
this should work on SP2 or 3 XP (although i haven't tried this myself), vista initial release and SP1

Bios saw 250gb. System Quite old. Running XP version 2002. SP2 & SP3 added separately post install. Above advice re admin tools/comp manage/disk manage didn`t work either.

"I would use more than 1 partition, in case something screws the one partition up. Then you'll have to start all over again (and it'll take longer to format)"

Have made a separate partition of the unallocated 104gb. You are probably right insofar as partitioning the disk as opposed to having the whole disk as one partition.

Thanks for the advice all. Cheers

769237 2009-04-29 09:11:00 Thats probably about right then, thats 231gb Speedy Gonzales (78)
