HI I used bit-locker in one of my harddrive partition, and it was working all fine. But one day i scanned my drive, while unlocked, with windows scandisk utility from drive properties. After scan it showed "scan disk found errors, and were successfully fixed", soon after a restart my drive is inaccessible, now it is asking to unlock the drive, and after typing password and clicking unlock button, it get unlocked but the windows explorer hangs, and says the drive is inaccessible. Please help as the disk contains a valuable data. I have the correct password and recovery key file also.
