attachments data loss , kindly help

[naveeid]

hi ,
i have large forum , having more then 200,000 attachment files.
few days ago i decided to make use of thumbnails instead of full sized images , and decided a new size and start rebuilding attachment thumbnails.
but it was taking too long, so i cancelled after few thousands.

after a few days , i decided to switch back to full size inline images instead of thumbnails.
it worked well. but now i have noticed that "some" posts are not showing attachments at all. and i am sure that the posts are having images attachments with them. but now they are showing absolutely no information about attachment.

so my question is that how can i fix this error. kindly help , its a serious issue for me as it has affected my forum traffic.

kindly help
