Here's all I know now. Looks like I'll get some stuff back. They tell me no one has brought them this much data on a single drive before to try and restore… I guess only a lunatic puts critical data on a high-volume drive! Anyway, this is what's happening now:
When we attempted to "mirror" the drive (sector by sector cloning to one of our own devices), we found the drive to be unstable, allowing intermittent access. This means that the drive sometimes starts up and seems to operate normally for a short (possibly very brief) time, then fails. We encountered many read errors in the process, which indicates the permanent loss of information on some parts of the drive. These types of problems affect file information (where the parts of a file begin and end) and directory information (names and addresses of files) and could affect some data segments (the actual contents of files).We feel that a degree of recovery in this case may be possible. At the end of the process, we will need to do a logical reassembly, which means to try to put the files and directories back together, attempting to get it as close as possible to its original configuration. If this succeeds, we then take a look to see what we have, and whether it matches the data required.
Fee If Data Required is Recovered: CAN $1600
Time Estimate: 4 days
