I've one partition on an external 2TB WD HDD encrypted with truecrypt that is refusing to open. I can mount the partition but, strangely, in the truecrypt window the partition mounts as \Device\Harddisk1\Partition0. When attempting to access the drive with windows explorer I receive an error stating "F:\ is not accessible. The parameter is incorrect". Only today has that error appeared, previously it said something similar to "Windows can not recognize this file system. Would you like to format it?". Restoring the volume header didn't work so I fired up chkdsk; it returns, Code: Checking the file system on the TrueCrypt volume mounted as F:... The type of the file system is RAW. CHKDSK is not available for RAW drives. Press any key to continue . . . Proceeded to use "GetDataBack for NTFS" and received another error stating the drive was FAT. Tried scanning the partition using the FAT version of the program and... yet more errors appeared. Code: Error: RangeError Range check error FAT:28 00695019 004D6A82-000D5A82 004D6DA9-000D5DA9 005D468B-001D368B 005D4B3E-001D3B3E 0066C099-0026B099 0041B9B2-0001A9B2 0043ADE9-00039DE9 0043D245-0003C245 0043D02B-0003C02B 0045009E-0004F09E 00458A68-00057A68 00699185-00298185 The program also displayed strange information under the details tab: http://i.imgur.com/eOtId.png So I'm thinking this HDD is ****ed, which is unfortunate for me because there is data contained in it I'd like to save. Any help/ideas on recovery would be much appreciated.
