3 . No Fdisk is : When Fdisk error No fixed disk present ( current hard disk can not be divided ) or run Fdisk but it will likely be suspended during Fdisk .
4 . Do not format the HDD : Hard disk format when conducting computer error Track 0 Bad - Disk Unusable .
5 . When the alarm is formatted Trying to recover allocation unit *** x . Now we know the cluster detectors for x *** damaged and it is trying to restore the cluster , but usually what we get is a bad sector !
6 . Running any application , receive a message like Error reading sentences data on driver C : , Retry , Abort , Ignore , Fail ? Or Sector not found on driver C : , Retry , Abort , Ignore , Fail ? A serious error occur or reading khi driver C : , Retry or Abort ? .
