Can't Format External HD. Wrong Capacity is Shown.

My HDD shows 500Gb of capacity in all programs of formating, partitioning, but it has only 80Gb (I'm sure). Can't format it because the programs try to format more than the HDD have of capacity. How do I format it properly? How much cylinders and sectors should I input to make it work? Thanks.

    use program called hd tune to read the model and smart of the drive to make sure the drive is healthy and google the model of the drive to see what the correct size of the drive is from the vendor model number info. if it is a 500g drive and not an 80g drive then your mb bios or chipset might be to old touse a drive of this size.
    if you can use cpu-z and post your mb info here (make and model).
  2. It doesn't support smart. I don't know the model, it gives me Generic (500Gb). It's written samsung, but it's probably from china. Benchmark in HD Tune doesn't work, I think it's because it's Raw. In the Error Scan gives me all damaged. Is it gone for good?

    CPU-z info: Intel DH55PJ AAE93812-302

    It's 80Gb in capacity, not 500Gb. I'm sure because it was working before I tried to format, and my brother had to add manually the capacity so that he could format.
  3. I'll try Seatools for DOS to restore factory max capacity. But I don't need more capacity, just less.
  4. see what the bios reads as the drive model info. and use try seatools to see what it says about your hard drive. your mb is new so it should if the sata or ide drive is set to achi or ide mode in the bios it should see the drive as the right size.
  5. How does Microsoft's UVCView utility see the external drive?

    Could we see a report from HD Sentinel?

    UVCView:
    Vendor: MOAI ELECTRONICS CORPORATION
    USB 2.0 SATA Bridge
    Manufacturer: Super Top
    Max paxket size: 64 bytes
    Interface Class Defined Device
    Mass Storage USB Device Interface Class
    Device Bus Speed: High

    I guess this is all the relevant info. I doesn't show more than that.

    Still downloading HD Sentinel.

    I saw a similar problem in another post saying that you can restore factory capacity in Seatools DOS, but I'm out of CD's to boot form it. I'll ask my brother to do that, because I'm travelling to another city and can't take the HDD with me. I'll try to see what the BIOS reads in about an hour because I can't shut down my pc now.

    After 80Gb it starts to give bad sectors because they do not exist physically.
    The Hard Disk Sentinel reads the HDD as Sumsung HM500JI, but it's from Taiwan. I googled the vendor read by UVCView. I just need to create a partition that does not use that part of the HD.

    UVCView is correctly identifying the USB-SATA bridge board inside the enclosure.

    HD Sentinel is correctly identifying the HDD behind the bridge as a Samsung HM500JI 2.5" 500GB SATA drive. What appears to have happened is that the drive's capacity has been cut by a HPA.

    See http://en.wikipedia.org/wiki/Host_protected_area

    You should be able to restore the drive's full native capacity using SeaTools for DOS (as already stated), or the HDD Capacity Restore Tool (Windows), or HDAT2.

    As for how this happened, I suspect that the drive was cloned, possibly in a Dell machine.

    Neither HDAT2 nor Seatools could detect my HD...
  11. Sorry, I should have said that those utilities require that the HDD is connected directly to a SATA port on your motherboard.

    Any ideia of how to it without removing the case and connecting directly on the motherboard?
  13. USB mass storage devices use a SCSI-like command set, whereas internal HDDs use the ATA standard command set. I don't know if there is any SET MAX ADDRESS command in the SCSI set, and I'm not aware if such an ATA command can be tunneled through to the drive by some other means.

    In short, I don't know.
