I've been experiencing problems lately, such as lag and freezes, so I ran the seagate tools to check the disk. It found 5 corrupt clusters, each containing data, which I fixed using the tools (it writes 0's to the corrupt cluster to see if it's usable still).
It fixed the clusters, but I get certain warning messages when I start windows, about corrupt files, and to run CHKDSK utility because the file is corrupt and unreadable.
It doesn't run CHKDSK properly, because it always freezes when trying to deal with some corrupt cluster on c drive. I would appreciate any info you could give me about fixing this problem. I don't care if the data in the clusters are lost, just that it can become usable again.
