Data Recovery help! HDD showing 128GB when it should be 750GB
i had begun to install windows on a 750GB drive the i currently had no OS on, just a bunch of other files. i got to the point in the windows installation where it asked me if i want to partition the drive or install windows in the current unpartitioned space, and at this point i quit the installation, fearing i would lose my files if i had gone any further. well wouldn't you know it, once i got the comp up with another drive with windows on it, i hooked up this hard drive and in my computer if you click on this drive it says "unformatted drive".
i have Recover My Files, which i began to use last night. that shows my drive as "RAW: 128GB". this drive is 750GB, with about 500GB of that being used. i clicked "complete format recover", and i let the program run all night and it just told me it found 577 files and 30,000 OS files (i never installed windows on it, i quit before i went past the partition part). the program was running 8 hours and the bar was about half way done. i clicked stop and checked the files it found and there's less than 10% of the files i had on that drive that were actually found.
i'd just like to add that i know about the 137gb barrier, the computer reads my 250GB drive just fine, so that shouldn't be the problem.
also, i scanned a drive i have that i know for a fact never had an OS on it, and it still found 20,000 OS files in the first few minutes, before i stopped the search.
any ideas what is going on?? am i doing something wrong or am i just screwed?
and i need another drive to save the files to if i recover them, right? can this 750GB drive be reformatted and used again when i am done?
