Op sys is on 250gb, reads as 127gb

  1. Hey guys.
    I setup my system on a 250gb hard drive but system reads it as a 127gb. I downloaded the software for converging it to its original form yet it won't let me as it is the C:// drive. If anyone can point me in a direction that might be able to assist, that would be awesome (i.e. a possible partition of the space that wasn't originally read?) THANK YOU!

    Do you have Windows XP Service Pack 2? That is the usual cause for this problem.
    If you do not, you mayl not be able to partition the drive to anything larger than 132 GB... 127 or so after formatting the partition.
    It becomes a catch 22. You could partition and format the hard drive to the 250 GB figure, if you had Windows XP Service Pack 2 to do the setup of the NTFS partition. It will work once as the full 250, or so, once it has Windows on it, but getting Windows on it prevents that.
    There are solutions online you should be able to find with a Google search, but they require jumping through a few hoops.
    One solution is to setup the hard drive as a slave in a computer that has Service Pack 2... or setup the drive with two partitions while slaved in another computer.
    Alternately, set it up as 127 GB, then upgrade Windows with the Service Pack 2 disk you buy from Microsoft for $3.40, then use partition magic or Acronis to enlarge the partition.

    From your guide:

    "SATA drives:

    "If running SATA with XP, it is NOT recommended to run SATA along with IDE/ATA. (Use one or the other.) XP sometimes gets confused where to look for the OS and normally defaults to IDE/ATA. You must have the appropriate SATA drivers when installing a SATA drive(s) on your system. XP does not default to SATA formatting otherwise"...

    Does this really apply any longer Tedster? I'm running 4 IDE and 2 SATA drives under XP and Vista. They are all represented correctly in the bios. The C drive is a 400GB SATA... No additional SATA drivers were needed

    "it is NOT recommended to run SATA along with IDE/ATA." Complete misinformation.

    Right Rick,
    I have an older ABIT IC7 motherboard that also handles IDE and SATA drives just fine. It was an expensive board in it's day though. I'm sure some motherboards/bios have problems with IDE/SATA, but to make a blanket statement like Tedster has is "mis information" for sure

    We have yet to see a problem with the combination of EIDE and SATA drives, but we have not seen that setup on an MSI K7N2.
    I don't think this ATA <-> SATA issue has anything to do with the problem about which Hashtoker requested help. The problem with large drives can be the same... if you are trying to format the full 250 GB with plain Windows XP, or Windows XP SP1 with an older BIOS.
    On some boards, including this MSI (as I understand it) you cannot exceed 132 GB without Service Pack 2

    Once again Tedster I call complete and utter BS, and beg for you to link to a credible, non-forum article indicating such problems, with extra points if it's from a Mobo maker indicating massive problems not specific to a single motherboard.

    I've said many times that I and many people run IDE and SATA in combination fine. I've asked many times for a link to prove your case, I have yet to see one. Frankly this misinformation has gone way too far.

    Tedsters guides are usually very helpful in many ways to many people... The "No IDE with SATA" is turning into an "Old Wives Tale" very fast

    I ended up using data lifeguard tools from western digital website. It created a partition of the previously unrecognized space. Thanks for the help.

    this is an old problem... soon to dissappear forever

    While the original guide is slightly out of date, it still holds true for older motherboards. Newer motherboards past NFORCE3 seem to handle both types. This argument was hashed many times here on TS.

    I still do not recommend it. There really is no need to mix drives and it can't be a good thing. Even if it works, you can potentially set yourself up for problems.

    SATA is far superior to IDE and is well established since the original guide was written.

    I'll continue to run both SATA and IDE for now. My full-tower computer is used as a "test bed" for IDE drives that have beed diagnosed with problems and have been "repaired" or discarded accordingly
