DISK DATA RECOVERY

Although most of us are used to saving data on computer hard drive, only very few users know the exact data storage principle. Do you know or do you want to know what really happens when data are written onto the hard drive. Then, we’ll tell users how to recover data from broken hard drive under the condition that hard drive is damaged logically.
 
Note: please read How To Fix A Broken USB Stick And Get Files Off It carefully if you are curious about how to fix/recover a broken flash drive.
 
During the process of data being written onto computer hard drive, they are encoded, actually. It is only the interpreting content of data that has been written to hard drive. When the data are writing, they are more like a wave form being transferring from someplace to the drive. Then, when data are read, they have to be interpreted back on its way out so that they can finally become 0 or 1.
 
We don’t need to understand the encoding and decoding process of data. We only need to be aware of the fact that data will be saved in sectors of hard drive when they’re written. And the minimum storage unit of data is cluster, which means, even if the size of data being written to hard drive is less than that of a single cluster, it will still occupies one cluster. After the first data are written here, no other data could be written to this place again unless the previous one is deleted or cleared.
 

Common Hard Drive Broken Signs

Though hard drive is relatively safer than other storage media, such as USB flash drive and CD/DVD, it could still fall victim to wrong operations and unexpected attacks easily. Therefore, if you encounter the following signs, you may as well conduct hard drive data recovery as soon as possible before hard drive is really dead. Otherwise, you may need to recover data from broken hard drive and the recovery result is uncertain.
 
BSY: this indicates drive busy.
DRDY: this stands for drive being ready to accept commands.
ERR: when you see this, you can confirm that the last result was an error.
DREQ: this means exchanging data with the host.
UNCR: if this appears, you’re meeting an uncorrectable error.
WRFT: this represents write fault, as you can easily imagine.
TONF: TONF means that track 0 is not found.
 
Of course, there’re other hard drive broken signs that indicate your hard drive is going to be or has been broken. Please take measures when you encounter any of these.
