Data Tape RecertificationWebuyusedtape's Recertification Process:
At Webuyusedtape, we call our process "Recertification", not reworked, re-manufactured, reconditioned or other names you may hear from other companies. As the only tape manufacturer that also offers a full line of Recertified media, we take great care and pride in our offerings. By Recertification, we mean writing a pattern of all one's and zero's, full length, every bit position to each tape, and recording the error activity encountered during the process. This not only assures that we provide our customers with a high quality Recertified media, but also ensures that your data cannot be read or ever recovered. Period. Think of what happens when you re-record a home VCR tape. Whatever was on that tape previously is gone - not recoverable. Even if the recorder records a blank screen, it destroys what was there before. The same is true with computer tapes of all types, including. Data beyond the overwritten area can be recovered, so to assure reading previously recorded data is not possible, the entire tape must be overwritten.
Our process is simple:
- 1. Receive tapes into a secure environment in our Webuyusedtape facility
- 2. Count, sort and inventory tapes received
- 3. Degauss and destroy any unusable tapes found during step 2
- 4. Immediately degauss all media that can safely be degaussed and reused (non-servo track media only).
- 5. Stage cartridges to be Recertified
- 6. Write a bit pattern on all one's and zero's on every tape, full length on production drives and log error activity. This process is completed using Webuyusedtape's proprietary MMPC, or Tapewise Software designed specifically for this process. This software does not invoke normal drive error correction capability in order to assure every bit position of the tape is overwritten.
- 7. The block size used during Webuyusedtape's Recertification process is 128K.
- 8. Tapes that fail due to high errors will be again degaussed and destroyed.
- Tapes that pass Recertification will be cleaned, volume ID labels removed, new labels applied and may be re-initialized prior to being shipped as Recertified media.
We have had visits from several major companies to our Webuyusedtape facility within the past year. In every case, our process to eradicate data in a secured manner has been approved to meet strict security requirements. If so inclined, we would welcome you or your designee to visit Webuyusedtape and verify our process first hand. The following article takes a point-by-point look
at a recent White Paper, "Recertified Cartridges--
The Hidden Risks."* At Webuyusedtape we
understand what it takes to make quality
recertified tape products. We also feel that
recertified tape products make economical and
reliable alternatives to new tape.
As opposed to Recertified Media; Used,
Reconditioned, Reworked, and Remanufactured
Media all raise questions about the process
involved in producing these products. In these
cases there may not be published specifications
and warranty information available so the
customer can see exactly what they are receiving.
We would also ask, "how can the user identify
which product came from what vendor and how is
any verbal warranty implemented?"
At Webuyusedtape, we developed a solution to
this issue by providing published specification and
warranty information for our recertified product,
and the term "Recertified" identifies our process
used to produce such media. We also give a
lifetime warranty on all of our recertified product.
We define recertified tape as media that is tested
on OEM tape drives and test equipment using
methods that were often employed in the 100%
certification of newly manufactured tape. Our
testing process utilizes our proprietary software to
insure that the error levels guaranteed are at least
as good as those demanded by Industry Standards
and/or ANSI for new tape at the time of production.
Point-by-Point Response to Claims Against
Recertified Media. Note: All claims against
recertified media are represented in bold in points 1-
7**, and Webuyusedtape's response follows.
(1) "Using Recertified tape cartridges (cartridges
resold after their initial purchase, and sometimes
use) can introduce unforeseen risk into IT
departments."
Manufacturers typically offer a long warranty period
on their new tapes, and for a manufacturer to suggest
that the new tape will last for many years in the
hands of one owner but would not last as long if the
ownership changes hands surely does not engender
much faith in the manufacturer's product. The tape
has a specific warranty period. If it's a quality
product, it should last that period regardless of the
number of users, providing the data center maintains
a suitable environment. But even manufacturers state
in their specs that media exposed to environments
outside of recommended specs can still be used if
reacclimatized. This strikes us as contradictory, and
in any event if there is damage on the tape, it is
identified during Webuyusedtape 's recertification
process and this product is not sold through our
recertified program. The tape that Webuyusedtape
does recertify is obtained from state of the art data
centers that carefully manage their equipment and
media assets.
(2) "There are two primary reasons that
cartridges come into the hands of recertifiers. One
is when tapes experience "early life failure" due to
physical damage or exposure to some type of
debris or contaminant, resulting in unacceptable
error performance. The second is advancing
technology--a new tape drive purchase renders a
current media supply obsolete for a particular user."
Webuyusedtape does not accept physically
damaged media, and even tapes with more than
slight cosmetic blemishes are disqualified for use
during our recertification process. Of the tapes we
initially acquire, we certify them on IBM, STK,
Quantum and other drives using software
developed to test for errors at often better error
performance criteria than industry standards
dictate. Any data that remains on the tape is not
usable/readable much in the same way that old
unreadable data resides in every overwritten tape
cartridge in every data center in the world. We
also accept many obsolete cartridges as well.
(3) "Media recertifiers purchase these
'discarded' tape cartridges, possibly run them
through a testing or 'recertification' process,
and then resell them."
As defined above, ALL tapes are put through a
stringent recertification process. Since many new
tapes are only "batch tested," our testing process
typically provides a higher quality level than for
many newly manufactured tape cartridges.
Webuyusedtape pays the owner of this media a
premium price to buy it back and recertify it. The
manufacturer is only in the business of providing
you with new media and not interested in
providing intelligent asset management by
offering any type of reasonable buyback of media.
(4) "The question of whether to go with
recertified tapes is one that speaks to the cost of
operations and the value of an organization's
data. From an operations standpoint, Gartner
Group places the cost to the average data center for a job
ab end at $1,000. If job abends from recertified
media increased by just one per week, it will cost
the data center more than $50,000 in operating
expense, not including the cost of any missed
SLA's (Service Level Agreements) due to failure
to complete a job or process on time."
Using our quality recertified media will prevent
costly re-runs. Experience shows that when
recertifying tapes from data centers, we typically see
a 10% fall out. This means that properly recertified
tape will actually decrease, not increase, the number
of abends a data center experiences with their own
non recertified or used tapes.
(5) "In a perfect world, cartridges
would be transported, stored, handled, and placed
in operating environments that are clean and
impart no stress or damage to the cartridges.
Under these conditions most magnetic media can
last more than 25 years. However, history has
shown that the most likely cause of a tape's early
life failure is handling damage."
Since Webuyusedtape removes all damaged tapes
from the original lot, the buyer can be assured that
the tapes were in perfect condition when they were
sold to you or your company. This is an additional
advantag to recertified media.
(6) "Debris is another source of early life
failures for a cartridge. The major sources for
debris are contamination from within the data
center, debris exposure during shipping or
transportation, and cross contamination from
problem cartridges. As with handling damage,
the effects of debris contamination may not be
immediate, and may take some time to develop.
Even one piece of debris can become embossed
or result in a "print through" to adjacent layers
of media by distorting the base film."
This is true , which is why our tapes are certified
on IBM, STK, Quantum and other drives by
software developed to test for errors at often better
criteria than IBM/ANSI standards specified. When
debris errors are detected, the cartridge is
immediately removed from the recertification
process. The process of recertification uses a tape
scraper blade and vacuum system within a drive
which cleans the tape surface by removing debris.
(7) "When considering what recertified media
offers, you should ask yourself some critical
questions on the balance between media cost
and the potential costs of recertified tape issues.
How many more errors do you allow on a
recertified cartridge compared to a newly
manufactured one? How many errors define
end-of-life for a cartridge? Buyers should be
aware that recertified media may have a
shorter useful life than new tapes and may
likely result in poorer performance for the entire library.
Do we monitor error rates for the tape system to
identify drives that need service or media that
may need to be retired? The use of recertified
media may cause system error rates to go up,
triggering excessive drive service calls. For many
data centers, these excess service calls are now
billable items even if basic maintenance is
included in the service contract."
Our recertification process includes criteria for
temporary errors. At Webuyusedtape, we think it is
better to recertify tapes and make sure these criteria
are not exceeded. In regards to "useful life," we see
typical usage of media as being between 1 pass and
2,000 passes depending on the nature of the process,
yet we see that manufacturers typically claim much
more than this indicating to the user a large safety
net. We therefore do not see "useful life" as an issue.
Manufacturers specify their warranty as for time
periods and usage rates. In all instances, products that
are put through our recertification process come
within those guidelines. Further, we believe that
tapes get damaged and degrade in all environments.
But a three year old tape that is recertified will hold
up better than three year old tape that is not
recertified, and we prove this by pulling out typically
10% of all used media we receive for this program.
The recertified media supplied is current vintage
product with lifetime warranties. The age can
therefore not be an issue. Our clients continue to
return for future orders because they trust the media
from experience and it saves them a lot of money.
