i think i've lost the header to one of my internal disks ( maxtor 160gb). this is a storage only disk, and contains no software but regularly accessed files. after a system reboot, the disk name was magically reset to 'local disk', and the file system changed from ntfs to raw. whenever i try to access the disk in any way, windows simply prompts me to format the disk. the disk is otherwise fine in winxp and bios, though apparently unformatted. foolishly, the data is not backed up (waiting till i can afford a server), so one way or another i want to recover it. i have tried to diagnose the disk in norton disk doctor, only to be told that the disk contains no recognisable format. i've tried the disk investigator app, but it pretty much just tells me there's nothing on the disk. i have also, on advice, run fdisk /mbr on the disk to no apparent effect. is there a convenient way to recover the disk header or do i have to recover the data to a secondary location using recovery software? i'd rather not have to resort to the latter, as there is about 100gb of data, and i don't have enough contiguous space on my system. should i try to create a disk image before i continue?
