Indaily computer use process, we may usually encounter data loss problems. Manyusers may be confused about why data gets lost. Let’s analyze the data loss reason. The information about data lossreason is helpful for us to protect data. Hard disk failures can be dividedinto two kinds: logical bugs and software bugs.
Diskdata loss for logical bugs:
Logicalbugs are divided into artificial damage and non-artificial damage. Artificialdamage means the data damage or data loss is caused by artificial reasons, suchas virus infection, accidental deletion, accidental formatting, accidental partitioningoperation, accidental overwriting. You can avoid these problems if you arecareful enough when operating computer.
Non-artificialdamage means that the data damage and data loss are not caused by users, such as data losscaused by software bugs, 0 track damage, hard disk logical locking, accidentalpower-off, electromagnetic interference, system error or system crash. Userscan hardly avoid these situations, so we should back up important data at alltimes.
Ifdata is lost for these problems, can we recover lost files? Ingeneral, logical problems will not cause data to be lost thoroughly. It justdamages data file table, but data is complete, so the data recovery software likeMiniTool Power Data Recovery can easily recover files. But once data suffersdamage, we can’t write data to the original partition to avoid the situation wheredata is overwritten and can’t be recovered. Don’t format partition or recreatepartition, because these operations will cause irreversible data damage. Don’tuse data recovery software without guarantee, or it may cause multiple damageswhich increase data recoverydifficulties.
Diskdata loss hardware bug:
Dataloss may be caused by reasons below, such as disk being scratched, Magnetichead being out of shape, Magnetic head amplifier damage, Chipset damage orother component damage. Hardware bug generally shows that system can’trecognize hard disk, and there are always other phenomena that crashing noiseoccurs, and that motor doesn’t turn and there is no sound when power is on, andthat read-write errors are caused by inaccurate head position. These situationswill occur:
Firstly,system doesn’t find the hard disk when we boot computer, and there is not anyerror prompt. Be careful about that when bugs occur in hard disk, somemainboards will give corresponding prompt information and prompt code. If thepower source and connection have no problems, we can know the hard disk mayhave bugs.
Secondly,computer booting costs very long time. When we operate certain software, errorsor slow reading files response always occur, and we hear disk noise at the sametime. At this time, we should be careful about that hard disk magnetic head mayhave some problems. We should timely take measures to protect data and ensuredata security.
Thirdly,system can’t boot through hard disk when we restart computer. After U diskboots, we can see hard disk drive letter, but can’t get in. This situation isserious because hard disk booting sector may have problems. Mayberepartitioning operation can not be performed or maybe after repartitioning operation,the information can’t be written to the main boot sector.
Finally,abnormal sound occurs when we normally use hard disk, and then we can’t findthe hard disk. But after we restart the computer, system finds the hard diskand operates normally. In this situation, maybe the hard disk aging occurs. Weshould perform data protection measures, and replace hard disk to solve theproblems.
Ifencountering hardware bugs, we have no methods to solve the problem, so we haveto turn to hard disk manufacturer or repair shop. However, they are just incharge of hardware repair, but do not ensure data security. So we have to takemeasures to prevent hard disk bugs. The best way is to pay attention to backingup important hard disk data and preventing data loss.
