solved that problem na..
ganito , if may extra pc ka dyan ,
iconnect mo na lang yung HDD ng ayaw mag boot sa extra pc
then after ma-detect at ma-install ni extra pc yung hdd
right click sa hdd then properties
then tools tab , error-checking then click mo check now
be sure naka check yung automatically fix file system error saka mo i-start
mostly after this steps , nag bboot na ulet yung HDD..
feedback mo n lng ako if anu results..
