I have a drive with a few bad sectors that I have no intention of using
for anything important. I'm always testing operating systems and often
will load and delete several a day...so this drive would be fine for that.
I zeroed it out using "dd" but before I did so, I looked at all the
options in hdparm .
One option was to deliberately create a bad sector.
I imagine this is for some type of testing purposes..
Just curious as to why someone would want to do that.
Interesting point as to my "credentials" and the use of terminology.
For the past 25 years, I've been repairing computers.
At one time I was constantly busy and often had three on the bench at once.
Because I worked out of my house...I was just an amateur but because I
got paid, I could be considered a professional.
For nine years however, I did volunteer work for an NPO , so wanted to
be sure everything I did was legit...so got "certified" and became an MAR.
Though this type of work would qualify me as a professional, because I
was a volunteer...I did not get paid. Anyway...all the computers I
refurbished were legal and by the book. No way did I want to get the organization in trouble.
Kind of interesting though hoe some of their providers "ripped off" this
very good, non-profit agency.
A local outfit, to be nice, provided them with a free server...but still charged them a monthly fee (I think $200). They did absolutely nothing.
One day their entire system came almost to a halt and their provider
said it would be a few weeks before they could get there, I was asked to
take a look.
Every machine in the organization was on the server...at least 25 units.
Only 12 were actually used for work.
The rest of them I took off the server.
They were mostly Linux machines I had setup for the members to browse ,
etc. ( They required no maintenance other than occasionally having to
delete all the .exe malware piled up on the desktop)
Anyway, with only 12 machines on the server...it was smooth sailing.
I did return on the weekend to perform all the updates which were never applied and update to unapproved drivers to the correct ones.
I also told the director to fire the IT firm, which she did.
They found another who would only bill them for work done.
Additionally they were paying $100 a month on a maintenance contract for
there video surveillance system. One day it failed and they were called
in. The whole thing was running off a Win2k machine..which the company
said was unsupported and they did nothing.
I repaired the computer and told the director to fire the company, which
she did. I then had them purchase an entirely new security system for
the total price of $200.
It was considerably better than what they had.
