I have 4 Partitions on my SAMSUNG F3 HD103SJ 1TB hard disk(C,D,E,F). The problem only happens with the E: Drive(232GB). Whenever i download a file in that drive it becomes incomplete after i restart my PC. It doesn't happen with every file. For example if i download a 100mb torrent in that drive and complete it, after i restart my pc and force recheck it, it will suddenly become 90mb and utorrent will show data is missing in the middle of the file. I didn't ever force recheck without restarting my PC, so i don't know if it has something to do with restart or not. I always properly shutdown my PC. Few days back i downloaded an Anime in that drive and all the episodes had CRC in the filename. I checked the CRC's and everything was fine. A week later when i rechecked the CRC's using RapidCRC it showed that 2 of the files had a mismatch. This happens with exe files too. I checked my Hard Disk using the Error Scan of HD Tune Pro 4.61 and it didn't show any errors or bad sectors. Then i scanned that drive using chkdsk /R and after checking for 1 hour it didn't show any errors. It has become a regular routine, almost all the torrents which are larger than 5 GB needs to download another 100 or sometimes 500mb to re-complete them. I am using Windows XP SP3 32-bit. Can anyone kindly tell me what can i do to solve this problem?
