The hard disk is the software warehouse responsible for storing our data. If the fault of the hard can you install windows recovery on usb from mac disk is handled improperly, the system will not start and the data will be lost. Then, how should can you reach windows 10 recovery with usb keyboard we deal with the common faults of the hard disk.
Common fault 1: The system does not recognize the can you recover a hard drive hit by lightning hard disk
The system can't be booted from the hard disk, and can't enter the C disk even when booting can you recover data deleted from a usb stick from the A disk, and the existence of the hard disk can't be found using the automatic monitoring can you recover data from a bad hard drive function in CMOS.This kind of failure mostly occurs on the connecting cable or IDE port, and the can you recover data from a broken hard drive hard disk itself is unlikely to fail. You can perform a replacement test by re-plugging the hard disk can you recover data from a burned hard drive cable or changing the IDE port and cable, and you will quickly find the fault.If the newly connected can you recover data from a clicking hard drive hard disk is not accepted, a common reason is the master-slave jumper on the hard disk. If two hard can you recover data from a corrupted hard drive disk devices are connected to an IDE hard disk cable, the master-slave relationship must be clearly can you recover data from a crashed hard drive distinguished.
Common fault 2: Hard disk can't be read or written or can't be recognized
This can you recover data from a damaged hard drive failure is generally caused by a failure in the CMOS setting.Whether the hard disk type in CMOS is can you recover data from a dead hard drive correct or not directly affects the normal use of the hard disk.Current machines support the "IDEAutoDetect" can you recover data from a degaussed hard drive function, which can automatically detect the type of hard disk.When the hard disk type is can you recover data from a destroyed hard drive wrong, sometimes the system simply can't be started, and sometimes it can be started, but read and write can you recover data from a drilled hard drive errors will occur.For example, if the hard drive type in CMOS is smaller than the actual hard drive can you recover data from a dropped hard drive capacity, the sectors behind the hard drive will not be able to read or write. If it is in a can you recover data from a failed hard drive multi-partition state, individual partitions will be lost.There is another important reason for the can you recover data from a faulty hard drive failure. Since the current IDE supports the logic parameter type, the hard disk can use "Normal, LBA, can you recover data from a formated hard drive Large", etc., if the data is installed in the general mode, and it is changed to another mode in CMOS can you recover data from a formatted hard drive , There will be a hard disk read and write error failure, because the mapping relationship has been can you recover data from a melted hard drive changed, the original correct hard disk location will not be able to be read.
Common fault three: can you recover data from a reformated hard drive the system can't be started
This failure is usually based on the following four reasons:
1.The can you recover data from a reformatted hard drive main boot program is corrupted
2.Partition table corruption
3.Partition valid bit error
4.DOS can you recover data from a ssd hard drive boot file is damaged
Among them, the DOS boot file is the simplest to be damaged. After booting with can you recover data from a usb flash drive the boot disk, just transfer a boot file to the system.The main boot program damage and partition can you recover data from a wet hard drive effective bit damage can generally be solved by FDISK/MBR forced overwriting.It is more troublesome can you recover data from a wiped hard drive if the partition table is damaged, because the partition can't be recognized, the system will treat can you recover data from an encrypted hard drive the hard disk as an unpartitioned bare disk, which causes some software to fail to work.
There is can you recover data from an old hard drive another form of partition table corruption. Here I call it "partition mapping". The specific manifestation can you recover data from damaged external hard drive is that there is a partition that is the same as the active partition.The same includes file can you recover data off a broken hard drive structure, content, partition capacity.If the content of the partition is changed in any area, it can you recover deleted data from a hard drive will be reflected in another place, as if it is the shadow of the mapping.I have met, 6.4G hard drive can you recover deleted data from a usb stick becomes 8.4G (2G area C is mapped).This kind of problem is particularly embarrassing. This problem can you recover deleted data from external hard drive does not affect the use. If it is not repaired, there will be nothing wrong. However, when it is can you recover deleted files from a usb drive necessary to repair, NORTON's DISKDOCTOR and PQMAGIC have become blind, turning a blind eye to the can you recover deleted files from external hard drive inconsistency between the total partition capacity and the actual size of the hard disk. I'll talk about can you recover deleted files from portable hard drive you without any problems.To deal with this problem, only GHOST overwrites and restores the partition can you recover deleted files from usb flash drive table with NORTON rescue disk.
Common failure 4: bad sectors on the hard disk
This is a shocking can you recover deleted files on external hard drive and scary word.Recently, IBM's word of mouth has also gone down because of this.When you scan the can you recover deleted photos from external hard drive hard disk with the scandisk program SCANDISK that comes with the Windows system, the system prompts can you recover deleted pictures from external hard drive that there may be bad sectors on the hard disk, and then flashes a horrible blue, and the small yellow can you recover desktopyour material from a hard drive squares slowly spread out. A certain square is marked with a "B".
In fact, most of these bad can you recover encrypted data from formatted hard drive sectors are logical bad sectors and can be repaired.There is no need to send for repair at all (it is can you recover factory settings with new hard drive said that the reason why the manufacturer developed the self-check tool is because half of the hard can you recover files after formatting a hard drive disks that can't be repaired can not stand the "cruel" fact that half of the hard drives are good at can you recover files after formatting external hard drive all).
So, when such a problem arises, how should we deal with it.
Once the "SCANDISK" is used can you recover files deleted from a usb drive to scan the hard disk, if the program prompts that there are bad sectors, first of all, we should re- can you recover files deleted from external hard drive use the self-check program of each brand of hard disk to perform a complete scan.Note, don't choose can you recover files from a bad hard drive quick scan, because it can only detect about 90% of the problems.To reassure yourself, it's worth can you recover files from a broken hard drive spending more time here.
If the result of the check is "successfully repaired", it can be determined can you recover files from a corrupted hard drive that it is a logical bad sector, and you can pat your chest to catch your breath; if not, then there can you recover files from a crashed hard drive is no possibility of repairing. If your hard drive is still in the expiration date, then replace can you recover files from a damaged hard drive it as soon as possible. Bar.
