Corrupted boot sector or partition table in non system disk
Hello,
I had a non-system disk installed on my computer, NTFS formatted, ~75 GB. I had to disconnect it, and then when I reconnected it, it was not recognized. After fiddling around with the computer management console, it finally recognized it, but through my efforts, I seem to have corrupted something, boot sector, or partition table, or something, because now it is inaccessible. If I click on it, it wants me to format it.
Using various software on the web, I have basically ascertained that it is now comprised of an unknown partition of 74.5 GB, and an unallocated partition of 2.49 MB. I tried PC File Inspector File Recovery, and it couldn't find anything... said there was a bad boot sector, that's all.
Any advice on how to repair this problem, without paying?
Any help would be greatly appreciated.
