|data recovery from server
Editor:- August 4, 2016 - data recovery from memory... is
that even a real thing? - some of you may be asking.
In the past its
viability depended on several factors - including - how long was it since power
was turned off.
Now in many markets (web scale server and embedded
gadgets) we're seeing a crossover of SSD and SCM architecture concepts.
And due to the past success of
PCIe SSDs in servers -
we're also seeing new memories
It was those thoughts which led to my blog -

introsepctive insights from SSD recovery market
January 23, 2015 - It looks like the market for
recovering data from
flash SSDs is finally starting to grow up and share useful introspective
insights such as:- the comparative incidence of DR for SSDs versus HDDs with
the same usage patterns, and the most likely causes of SSD failure which are
likely to lead to a data recovery. ...read the article on

SSDs or hard drives? - the data forensics differences
October 23, 2012 - When you need to retrieve critical unbacked up data from a
damaged notebook (which you left in the car when you clambered out the
window after realizing that the puddle across the road was much deeper than you
first thought) you call the process "data recovery" - but
when a court seizes a suspect's notebook to try and retrieve data which may have
been deliberately "deleted" - they call it "data forensics"
- either way - in the most demanding cases the experts who work on these tasks
are the same.
SSD Data Recovery
(as opposed to dumb flash memory recovery) is a relatively new market which
didn't exist 5 years ago.
A recent article
SSD Drives Destroy Court Evidence - on a site called
ForensicFocus.com - discusses how
techniques which are essential to the operation of flash SSDs (such as
and wear leveling)
mean that from the forensic viewpoint SSDs yield up potentially much less
deliberately deleted recoverable data than hard drives.

CBL Data Recovery Launches a Different Type of Data Recovery
ON / ARMONK, NY - July 29, 2008 - CBL Data Recovery Technologies Inc.
today announced a new service offering which shields computer users from the
expense of data recovery when data loss disaster strikes unexpectedly.
The CBL Data Recovery Service Protection Plan provides 3 years of unlimited
data recovery coverage of a hard drive for $99.99.
"It's not a matter of if data loss will happen; it's simply a
matter of when," said CBL's President and CEO Bill Margeson. "The CBL
DRSPP is a preemptive, affordable alternative to standard data recovery service
fees which can exceed $1,000 when physical damage to a hard drive prevents
access to files. For some computer users, such an unplanned expenditure is not
financially feasible. The CBL Data Recovery Service Protection Plan shields them
from the unexpected expense."
Eligibility? - Any make or model of new and existing internal or
external hard drives are eligible for DRSPP coverage. The hard drive must be
functional at the time of registration and accessible from a computer running a
Windows operating system. The hard drive's serial number is captured during
online registration so when a DRSPP customer incurs data loss, they simply ship
the registered hard drive to CBL. CBL DRSPP coverage extends to data loss
resulting from virtually every cause including user errors, mechanical or
electrical failures, software malfunctions, viruses, and natural disasters.
The CBL Data Recovery Service Protection Plan offers 1 or 3 years of
coverage for $49.99 and $99.99 respectively inclusive of parts, laboratory
time and labor. Shipping and applicable taxes are extra. CBL DRSPP coverage
commences 30 days after payment and registration. ...CBL Data Recovery profile,

You could argue that if users thought ahead they would spend
their money on backups. But backups frequently go wrong - or can be affected by
the same common mode failures which render the original data media unreadable

the new business model is - and (if so) how long it will be before it gets
