Bad sector repair software




This article is devoted to teaching you how to detect and repair bad sectors and how to recover data when the hard disk has bad sectors by using bad sector repair software. Bad sector can occur on both hard drives and SSDs. A few bad sectors do not indicate that hard drive is surely to fail, as some bad sectors can be repaired successfully. There is no need to be panic when you encounter bad sectors, you should always keep calm and follow this guide to get them repaired.




A bad sector is a sector on a computer's disk that cannot be used due to permanent damage (or an OS inability to successfully access it), such as physical damage to the disk surface (or sometimes sectors being stuck in a magnetic or digital state that cannot be reversed) or failed flash memory transistors.

Something weird will happen if the hard disk has bad sectors, for instance, operating system can't boot normally; hard disk can't be formatted; when you open a file, error is reported. These phenomena show that there must be bad sectors on the disk. In fact, it is very common that disk used for a long time has bad sectors.

Bad sector repair software

You can click the button "Repair" to fix bad sectors. For more information about bad sector repair software and bad sector repair, please refer to the PartitionGuru online help Verify and Repair Bad Sectors

Important

The bad sector repair destroys data on the disk; more exactly, it destroys data on bad sectors or near bad sectors. Thus, you need to back up data before the bad sector repair. PartitionGuru reminds users this in a clear way, as below:

It is common that the disk can't read data due to bad sectors, and in such a condition, you need to recover data first instead of doing the bad sector repair.

Besides, the bad sector detection conducted by PartitionGuru doesn't do any harm to data, so you can use it without worries.

PartitionGuru itself is a piece of excellent data recovery software, so you can use it to recover data when the hard disk gets bad sectors. For more detailed information about this data recovery software and partition manager please go to: http://www.eassos.com/partitionguru.php

More on bad sector

Why bad sectors come up?
One of the reasons is that hard disk has bad sectors when it is manufactured; experienced data recovery engineers know which disk is likely to have bad sectors judging by its brand, manufactured time, working hours, etc. Another reason is the improper operations such as unduly defragment.


Fix bad sectors timely and use the disk with cautious
It'll become a vicious circle if you don't fix bad sectors timely, because that may cause more bad sectors. Therefore, you'd better detect bad sectors regularly and do bad sector repair timely. Meanwhile, though bad sectors are fixed, the disk is more risky of getting bad sectors than normal ones. So you should be cautious when you use a disk that had bad sectors before and do not save important data on it.


Logical and physical bad sectors
There are two types of bad sectors, logical bad sector and physical bad sector. The logical bad sector can be fixed, while the physical bad sectors can't be repaired, but usually they can be remapped. Bad sector repair and detect software can detect bad sectors, repair logical bad sectors and remap physical bad sectors.


Low-level formatting (LLF) and bad sector repair
Low-level formatting can be used to fix server bad sectors. However, the low-level formatting is a double-edged sword; it can fix bad sectors as well as do hard to hard disk, especially when the hard disk has physical bad sectors. Thus the low-level formatting is the last choice of bad sector repair.


Bad sector and new disk
It is barely known that when a hard disk is manufactured, there are areas on the platter that have bad sectors! These bad sectors, hidden in P-LIST and G-LIST, won't affect normal use and they can't be accessed by common software either. G-LIST can store several hundred bad sectors and the P-LIST can store about four thousand bad sectors. For more information about G-LIST and P-List, please read related articles.

"dear sir my pen not open and opening problems and not data delete problems "

"I really had to reply to Hafez. How is it the software's fault for bricking your drive if you forcibly interrupt the scan process? First off, you don't indicate just how long is a "long time" and second, you do not indicate how big your drive is? For instant recently I had need for a 1 terabyte drive to be examined, it took an hour and half with no faults find. How do you expect the software to process such a fault? Surely you don't think it is done instantly? It has got to find the fault, try and access it and fix it if it can (which means you have give it time to do its thing) and if it can't log it. The only other question is why on earth would you attempt to use software on a fault that you knew couldn't be fixed?? Did you bother to check whether or not the program was actually running or if it had stopped running?? I don't think the program deserved the one star, more likely you do"

"my drive disk has bad sectors,I used "partition to image file" action, i knew it couldn't do it because of the bad sectors but i just wanted to try anyway, but hanged in the middle for long time and it wouldn't close, so i forced it close and now my drive is inaccessible too."
