I believe this is what may be confusing TestDisk, and possibly other software as well. That is, LBA 0 is both a boot sector and an MBR (including partition table). The number of "hidden sectors" is 0, which means that the partition begins at LBA 0, not LBA 63 as in the case of physical drives. Your TrueCrypt volume has a FAT32 file system with a sector size of 512 bytes, 128 sectors per cluster (64KB), 2 FATs, 1 sector per track, 1 head, and a volume size of 0x320c8000 sectors (= 429916160000 bytes). That is, the drive is laid out as a logical volume rather than as a physical disk, hence no partition table is required. A screenshot is attached.Īs I suspected, the partition table is blank. When I run Testdisk, it says that the boot sector is ok but that the first sectors are not identical. It says that the filesystem is corrupted and cannot be read. Now the message that I get on mounting this volume is somewhat different. I followed instructions and rebuilt the boot sector. I then tried to fix this using Testdisk 6.11. The hard disk also appears to be working within normal heating / sound limits. Data in the outer volume is still accessible. TrueCrypt (7.0a) does mount it but there's a message which says that Windows XP does not recognize the filesystem. The filesystem was FAT32.Īll of a sudden, for no obvious reason, the hidden volume is not accessible. A hidden volume (400 GB) was created underneath the outer volume. I have a 500 GB Seagate Freeagent disk, which I encrypted on Windows XP using TrueCrypt 6.0. And I thought I'd buzz you guys for some help. I have a problem which appears to be a little bit beyond me.
