How to Perform Better data Recovery on Drives with Long Physical Sectors?
If you are looking forward on data recovery how to Perform Better data Recovery on Drives with Long Physical Sectors, follow these steps:
The interface size of different physical sector drives is 512 bytes. Thus, the data recovery of software and hardware should be accomplished using the ATA commands for accessing the drive.
These drives do not bestow any ATA commands for accessing the physical sector directly. Hence, you should be connected to the drive with the aid of 512-byte Logical Block method.
The first byte of data transfer should be starting at the first byte of physical sector where the last byte of transferring data should end at the last byte of physical sectors
This rule is a prerequisite for enhancing the performance and achieving high imaging speeds. It is imperative for the drives that have the cache limitations.
The primary reason of block alignment is avoiding unnecessary access to the physical sectors that cross the beginning or end of read block. The drawbacks of not following the rule are:
- The unaligned physical sectors are accessed two times during the imaging process. This causes extra wear on the drive during situations when the sectors are responsible for read instability issues.
- The adjacent read blocks which are crossing the similar unaligned physical sector may result in a similar proper.
If physical sector leads to instability issues including bad sectors while accessing LBA located in the PBA will be responsible for a similar outcome.
It is recommended to take the imaging process into account for avoiding unnecessary read attempts which can cause further wear on the drive and involve higher risks of failure of drives.
The unnecessary read attempts may enhance the imaging time in a significant manner. The processing problematic areas are counted to be the longest part of the process of imaging. Hence, the total imaging time may get doubled and tripled.
