External HDD became SATA diskette

I was installing some drivers from the ASRock utility disc when it asked me to generate serial ATA driver diskette. Foolishly, i typed Y twice forgotting that my external HDD was plugged in.

Now it has become a SATA diskette and it only reads 1.44mb instead of 1tb. Any advice on converting it back to its original state as I have a number of drawings in the HDD.

  1. I didn't know that you can convince a computer that a SATA hard drive is a 1.44MB Floppy disk...

    You could try looking for the currently used drivers for it, removing them, and installing proper drivers, maybe from the driver's website or from that of ASRock if it is the SATA drivers themselves, not the hard drive's drivers, that need to be replaced (or maybe both).
  2. I don't really get it.

    The issue is that it is still read that it has a space capacity of 1.44mb. But, when i populate it, it shows 900gb++.

    Therefore, the question is that how am I to get it back to work as a normal HDD without having to jeopardize my data.
  3. I don't think that changing out the drivers would jeopardize the data.

    You mean re-installing the driver for the hard disk?
  5. That and maybe also the SATA ports (might be aggregate chipset driver(s)) if the hard drive's driver being changed doesn't work.
  6. @scarabs, I suspect that the ASRock utility has overwritten the beginning of the file system on your external drive. I would stop and take stock of the damage, and then formulate a plan of attack.

    To this end I would use a disc editor to first examine sector 0 of the HDD. If you could upload the contents of this sector, then we may be able to determine what happened.
