Diagnosis on my desktop computer: D drive is fine, but the C drive is kaput. D drive has the Voyant files and most of the other data. The C drive held the OS, the applications, the drivers, and, unfortunately, my e-mail. So it looks like I need to get a data recovery firm to haul all the Outlook/Express e-mail files out of the dead C drive. Grr.
But at least I don’t have to re-rip about 300 CDs for my music library (which would involve fighting off the giant spiders while hauling the CDs up from storage).
