Maxtor 6B300S0 SATA 300GB reads as 127GB
I had Windows XP Pro running fine on this particular drive, but decided to clone over a Win XP Pro x64 installation from a 200GB drive. This entailed moving the 300 from one machine to another (newer) machine where the 200 was in use. Once attached the new machine reported the 300GB drive as only 127GB in size. That's where I stopped; no cloning took place. Since then moving the drive back to the original machine, using partition software to look at the drive, nor anything else has revealed the drive to be anything other than a 127GB drive. What procedure can I use to return functionality? Maxtor's utilities are useless. I can have this drive attached to an ASUS A8N32SLI Deluxe, or GigaByte K8NS Pro MB, so either way the drive will be behind an 'onboard' controller.
Which partitioning software did you use to check the disk?
Have you already tried what Windows Disk Management says about the disks size? To do so, connect the disk to your computer; click Start - Run and type "diskmgmt.msc". Click the drive and check if all the partition space is used.

SET FROM BIOS to detect large Hard Drives. (Most of the times you motherboard will support). In default it will support up to 127GB.

if its not in the bios the drive partitioning sw should be from the MFR. this will install special bootsectors to be able to use the drive properly.

The OS on the 300GB drive is Windows XP Pro sp2, but it will no longer boot (sorry I forgot to report that). The BIOS is set with LBA to Auto. Under Windows XP Pro x64 the Disk Management tool reports the drive as 127GB. I have tried Acronis Disk Director Suite v10.0, Migrate Easy, Partition Table Doctor, and VCOM Partition Commander with the result that all see the drive as 127GB (regardless of which system the drive is installed to). The Maxtor Utilities report the drive as 127GB also. Maxtor's diagnostic utility (PowerMax) cannot be used as the drive is controlled by an embedded controller (per Maxtor).
if it wont boot.. load the xp cd. and select repair / console mode
then :
fixboot /mbr
then :
fixboot /mbr
You need to update your BIOS to exceed "the magic 127GB limit"
ASKER
Alright, repair console repairs the boot to the 127GB, but doesn't fix the drive so that 300GB can be seen/used.
My BIOS is up to date. Both systems have had large drives in use. In fact, this drive was working perfectly and all 300GB could be used. I'm hoping someone has seen this before, as in all my experience this should not have happened.

did you try to use the mfr disk to reinstall boot sector for windows on the drive?
Hi
I had the same problem months ago when i got my harddrive
what i did, i used a partition tool to format it, and i created 4 partitions (that's the maximum you can create)
there's another solution to get it, is to enable big LBA on the registery
here are the steps :
#click on Start->Run, enter "regedit".
# Navigate to the HKEY_LOCAL_MACHINE\SYSTEM\
# 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
# Then restart

if you go into the bios..it says that the HDD is 127Gb? or where does it report that?
The 127 GB limit is built into the BIOS. If you cannot get more than that, you need to go into the BIOS and fix that issue with different LBA addressing modes. Older MBs cannot be fixed, but the ASUS 8X series I know for a fact can address a 300 GB drive. I think the problem is, you formatted the drive on a system that did not recognize a drive bigger than 127 GB because of its BIOS limitation.
You will have to remove the partition on the drive, using the new ASUS board, then make a full partition of 300 GB. It should do this. Dont go any further if it does not recognize it. If so, look at the back of the drive at the jumpers, it might be set to "CLIP" at 127 GB limit. This is a common setting for drives last year.

The problem with that one, you first have to build it with your windoze source, but I agree, once built, it is good.
have you tried setting the cylinder limitation jumper on the hard disk?
ASKER
As far as I know there are no jumpers on the hard drive at all. I am going to try the UBCD today and see if I can get anything to work. I was able to use a utility (I forget the name) to see the cylinders/heads/sectors in use and noted that only about 1/3 of the heads were in use and about the same on sectors.
RMA the Hardrive with your computer supplier. It looks like it was mis labeled.
ASKER
Negative, at one time it was seen as a 300GB drive and functioned properly. I'm about to try the UBCD approach and will report back.
cool with me - gurutc
