Try mo DL ka ng HDD sentinel para makita mo ang status ng HDD mo btw try muna din e backup ang files mo hindi nayan good for the long run lalo na HDD ito
so nililipat mo laman ng HDD papunta sa laptop? baka naman may bad sector yung HDD ng laptop kaya nag hahang. try mo barya baryahin lipat para malaman mo kung ano issue.
Mag kakaiba ba ng size ang HDD ung sakin kasi kinuha q lng sa desktop ko..nag order aq ng enclosure... Baka kc hindi sukat dun d nag rereply ung seller
Which things you really do matter here ? Have you already tried to defragment it, format it or done all needed checks ? If all is done then does bad sectors are somewhere in bootable region ? If so probably just trough it out of the window really
