Now the help I need is how to recover the erased images from the Compact Flash memory chip. Norton's unerase detects no remnants of the JPG images.

Products like this one may help: http://www.datarescue.com/photorescue/spec.htm And there are some tips I found with Google (searching on just "unerase flash memory"--other combos may give even better hits): http://www.imaging-resource.com/IRNEWS/archive/v02/20000922.htm#beg With this tip: Beginners Flash: Unerasing Lost Images It happens. "My name is [unintelligible]. I erased my media card before I copied the images." Hi, [unintelligible]. We all make mistakes. Before you panic and do something (else) foolish, work on a good excuse. Here's a starter kit: 1. "I thought you copied them." Where "you" could be anything from an African violet to a goldfish to a cat to a spouse or a long lost relative already framed on the mantel. 2. "I pressed the wrong button." Nobody has to know no buttons are involved. 3. "It said 'Copy.'" Well, desperate measures call for desperate acts. OK, now panic. Get it out of your system. If this is your first time (oh, there will be others), start by deliberately making the same mistake again -- but to a second card or floppy. You can try all sorts of techniques on the second one until you find something that works. The first thing to realize is that -- whether you are using a Macintosh or a Windows PC -- your storage device is (no doubt) formatted for MS-DOS. Macintoshes have no trouble reading and writing MS-DOS media (and, just for the record, PCs can handle Macintosh media with third-party software). But neither of them is any good at running disk utilities on the other's media. Your Norton knows your native file system, period. So recovery of a DOS-formatted card is a Windows task. Unfortunately, Windows may see your card only as a network drive (where, as with floppies, deletions are not safely buffered in the Recycle Bin). And it's rude to reorganize the directories of network drives, so your usual unerase utility may not go there. But there's hope. No guarantees, but hope. Although there's precious little hope if you've already stored newer images on it. Or just reformatted the card. But you didn't do that. So to unerase from your DOS-formatted card you'll need access to a Windows computer with a card reader and software that will recognize your card and unerase your files. There are a number of unerase utilities that may help. We know of one 64-MB CompactFlash card saved by the shareware program Recover98 (http://www.lc-tech.com/r98exp.html) even after a few new shots were written to it by a Nikon 950. We've had no success ourselves with MS-DOS Undelete, Norton Quick Unerase (which has trouble with files as large as image files) and Unerase or shareware like Directory Snoop (http://www.briggsoft.com/dsnoop.htm) -- either because they wouldn't touch a network drive or couldn't find the first cluster of deleted files. The freeware program Emergency Undelete for Windows NT (http://www.zdnet.co.uk/software/free/utilities/file/sw35.html) sounds promising, but we haven't personally been saved by it. If you have a success story with any unerase utility, let us know about it at editor@imaging-resource.com and we'll pass the information along. These utilities know a little secret: the data on the card is not really erased. It isn't lost until it is written over the next time information is saved to its formerly protected sectors. Instead, an erase operation simply frees the file's disk space, overwriting the file name's first character in the card's directory with the Greek character sigma. It's faster and just as effective. If not secure. To actually erase the file, you have to write over every byte. And more than once, if you believe certain U.S. government specs. (That's what the Norton Wipe command is all about.) If you're lucky, your unerase utility will just ask you for the first letter of each erased file name it found. And a few keystrokes later you'll have your file right back where you hoped it still was. We made the stunning revelation above that everyone (except goldfish) makes mistakes. It's our intelligence misfiring, really. So take heart! But if you're really intelligent, swing the odds in your favor by getting into foolproof habits like deleting images only in your camera -- using your computer solely to copy and relying on your camera to subsequently delete. While looking at your images on screen. From the CD you just burned.
