No remedy to handle Bad sectors?

April 7, 2010 - PRLog -- No remedy to handle Bad sectors?
Few of the 'conventional' cloning products, hard drive duplicator and disk imagers are particularly good at handling disks containing bad sectors. Data Copy King is designed to handle hard drives that contain unreadable areas and unstable head stack with clicking noise after having performed hot swap of head or/and platter, and to ignore any damage in disk structures such as partition tables and file systems. For data recovery purpose, clone is meant to facilitate recovery the files.
In bad sector handling respect, Data Copy King adopts advanced technology and has equipped with unique features to deal with bad sectors effectively and image more safely.
1.    UDMA transfer modes and protocols
Persistent Strive for providing super transfer speed in hard drive duplication/data disk image, Data Copy King adopts the latest transfer mode: UDMA 6(133) and significantly elevated the transfer speed. So if the hard drive supports UDMA transfer modes and protocols, the disk image speed will reach its final best tested speed at 7GB/min and disk wipe speed at 8GB/min.
UDMA transfer modes and protocols significantly outperform regular DMA and are the transfer modes of choice for newer hardware. There are six UDMA modes for option: UDMA2 (33) / UDMA4 (66) / UDMA5 (100) / UDMA 6 (133), and UDMA 6 (133) is the latest fast transfer mode.
Meanwhile user can manually select a UDMA modes according to the condition of the hard drives; for instance, when the existing hard drive quite a lot of bad sectors users can opt low-speed transfer modes like UDMA2 (33) / UDMA4 (66), which can make sure more data are acquired.
Ultra DMA Mode   Cycle Time (nanoseconds)   Transfer Rate(MB/s)   Defining Standard
Mode 0   240   16.7   ATA/ATAPI-4
Mode 1   160   25.0   ATA/ATAPI-4
Mode 2   120   33.3   ATA/ATAPI-4
Mode 3   90   44.4   ATA/ATAPI-5
Mode 4   60   66.7   ATA/ATAPI-5
Mode 5   40   100.0   ATA/ATAPI-6?
Mode 6   20   133   ATA/ATAPI-6

2.   Intelligent positioning bad sector
Data Copy King can intelligently judge whether data on the bad sectors is able to be retrieve or not, thus it aid you to make decision of how to deal with the bad sector. Randomly skip sectors
3.   Intelligent retry
Customers want the data badly, while there are many bad sectors; therefore there must be a means to obtain the maximum data.
Data Copy King is designed with retry function to acquire customers’ data at most five rounds to access to the bad sectors. First round to read the hard drive forward quickly skipping bad sectors till first pass finished; second round the program attempts to read the sectors one at a time from areas where the initial bad blocks were found during the first pass. It does this by keeping a record or 'map' of the sectors for the source drive stored in an HPA on the target (or destination) drive so it knows exactly how much data has been imaged. Then the rounds cycle as former two steps. Thus It guarantees the success rate.
4.   In the course of hard drive duplication, Data Copy King allows user to skip a certain numbers of sectors according to the needs when confronting severe bad sectors. User can manually set the numbers of sectors which will be ignored among 1, 32. 256, and 52000; namely if the numbers was set to be 256, 256 bad sectors will be deserted in succession.
With the unique and practical features above, the capability of Data Copy King to handling bad sectors is beyond doubt. And Data Copy King is surely the powerful remedy of hard drives with bad sectors.
