well, thats true. i choose to clear way from paragon partition program, as i experienced this disaster when i tried to resize the cluster size. my knowledge using diskedit and delphi allow me to learn how the errors occured/formed and able to salvages about 7/8 of the content. the paragon partion manager wrote the wrong first cluster mark on every file/folder entry in every directory clusters, what would happend if i allow scandisk to repairs that error?? its offer rom-dos defragd, but it also states it doesn't support fat32. there also offfer defragw.exe which support fat32 when i download it, it turn out to be defragw.exe from winME. however i already using winme defrag, and its refuse to work with my partition. that one partition was about 80 GB with 4KBytes/cluster, and also contain a few .nrg files that larger than 3GB in size. i'm curious about this statemnet: is this one won't be plaqued by "too-many-clusters-to-defrag" problem?but, i will try the free-dos one, since my cd burner and floppy drive is currently not functioning well, and its provide source code to examine. Thanks for the information.
