Recovering data from faulty SATA hard drives
Background: SATA is an alternative
interface to the more common (but old) ATA/IDE specification. Some
advantages of SATA are -
The advanced features of the SATA interface is designed to replace
the ATA interface.
Data Recovery: Regardless of the interface, the mechanical
design of the hard disk remains essentially the same. Thus disks using
a SATA interface will still be prone to all the common
problems associated with hard disk drives. The specific
nature of a hard disk failure determines the likelyhood of recovering
the data stored on it . Typical failure symptoms you may find are and
the prognosis for recovery are given below -
- The hard disk appears dead and is
no longer recognized by the computer - This is often
symptomatic of electronic component or motor failure on the hard disk
assembly, the data written to the magnetic media on the platters is
frequently un-damaged and using various professional recovery techniques
can be recovered.
- The hard disk makes a clicking noise
- There are a variety of causes of this symptom, in all cases it's
important that the drive is powered down and advice sort. Continued
use can often further damage the drive and make the chances of recovery
more problematic. Diagnosed early the possibilities of recovery are
often optimistic.
- The hard disk is still accessible
but files on it are not - Often indicates corrupt
or damaged media sometimes as a result of the read write heads coming
into contact with the platters. Under these circumstances we advise
that the computer or external hard drive equipment is powered down
to prevent further potential damage or corruption. The possibilities
of recovery will depend upon the condition of the stored data.
In all cases it's important that the problem is diagnosed &
recovered correctly. Please call us for assistance.

Above: There is no external difference between
ATA and SATA hard drives, except for the controller board.
The old PATA ATA interface (bottom) uses a
40-pin parallel cable, the new SATA interface (top) uses a 7 pin connector.
