【求助】要如何修復系統錯誤啊??

最近有事沒事xp右下角就會跑出xxx系統檔案已損毀
請執行xxxxx程式的警告
之前這顆seagate sata就是出現這樣沒幾天後就掛了送一顆良品回
但我上seagate的網上用它的online掃硬碟程式又掃不出任何壞軌
但用它的system check時卻出現以下：
Results for volume C: (NTFS)

Volume Label:
Volume Size: 25.00 GB
Some files on the volume are open. This may effect the accuracy of the file system check and result in false errors.

The file system contains errors that need to be repaired.

Results for volume D: (NTFS)

Volume Label:
Volume Size: 55.01 GB
The file system contains errors that need to be repaired.

請問一下我該怎麼"repair my systme error"啊??
感謝...
