Ravi, first of all error 1104 in the VFP help states that the operating system returned an error while VFP was reading the file. iow this is not a TableValidate issue per se. I would check the hdd for errors. Then copy the file contents to a new file and new index. And then try to access the new file.

Secondly, SETting TABLEVALIDATE TO 0 is not a bad idea depending on the situation. For instance if a file is opened and closed very often then the validation will have some performance impact, possibly slight, depending on the hardware config, but there nonetheless. Also, VFP locks the header of the file during the validation process and this has implications in multiuser environments. Check the help on this but do not assume that if TABLEVALIDATE if off then that is necessarily bad. It all depends.
