Ever since I have moved to Window 2000, if the O/S crashes - yeah it does even though its not supposed to - for any reason, any open VFP form, and any form which HAS BEEN open since the last reboot is trashed. When I look at the SCT file with a text editor, it looks like the file has been overwritten with an single ASCII character. (I haven't looked at it with a hex editer to see which character)

When I first put Win2K on a machine, it was under FAT32, and if I bypassed scandisk, it was usually possible to make a backup and recover the files after which scandisk which would destroy the originals, although sometimes the files were crosslinked and unusable. Since I installed on a clean drive with NTFS, a crash means a tolal loss for every thing since the last backup or reboot, as I don't see anyway to bypass whatever scandisk like operation is performed on NTFS partitions.

BTW, I have installed Win2K - Retail version, and VS6 SP3 (now SP4) on 2 different machines, with diffferent hard drives, video card, NIC, sound card, CPU, and MB chip set, with the same results. At present the above list is the total hardware comliment of the new machine as I want to solve this problem before introducing additional hardware. I believe the above should eliminate the hardware as a cause.

Another developer tested his machine, by turning off the power with forms open for editing, and DID NOT suffer corruption. (I have had this occur when the power switch on the UPS was bumped to the off position and have tested this way myself. My files were destroyed in this scenario.)

As the other developer doesn't have the problem, and I do, it seems I must have something set incorrectly in VFP or Win2K. Has anyone else seen this and found a solution.
