OMG, where are the IT Police...
Just like Coffee, way too many users and so called experts today that have no OR little understanding of the principles. While one does not always need it, understanding many things from First Principles can be important when trying to resolve a problem...
With coffee, we often look at the most basic of things such as Beans and Grinder.
With IT today, many have little understand of the principles on how HDD and USB and other digital storage processes might work.
Take home message -
THEY CAN ALL FAIL !!!! And do so in may ways... AND virus attacks can be very nasty..
Backup and have a process. Grand father, Father and Son, all stored independently and validated; is simple and can save lots of stress. Also check, before ever over writing any good backup with a new version, as sometimes the new may not be valid...
6 hrs last night to recover stuff.
A: A lost contract and detailed drawings from a USB stick that was about 4 years old.... Ended up having to re solder some components :o ( If you want to pay the $$$ some places can actually remove the memory chip and place into a memory chip reader, if it is a hardware fail of other components. But not so cheep)
B: Very special photos of significant family events were lost / unable to be found and some pic's with masive grey sections in them. Canon 7D I think.. Cheep end of the Professional stuff.
Card hand been placed into a reader for copy of pics in raw and jpeg format to the PC for editing...[/li]
[li]Something happened ??? [/li]
[li]Camera and card taken to a so called Professional Photographer, who is touted as being an IT buff [/li]
[li]Said expert runs some software and recovers some pics and then recovers them to a new dir on the said memory card that is in question..... [/li]
[li]Then copies all pics to an external HDD and burns to 3 dvd's.[/li]
[li]Then formats the card to clean a possible virus (?) and gives it back to the owner. [/li]
Needless to say, the photos of significance were not their and said owner was very distraught. :'( :'(
Long story short ;D
After some careful planning and getting the FULL story; I was able to reverse some of the actions, generate a image and then perform a number of processes without causing further data loss. I / they were lucky as I fully recover what I believe was
98% the images lost and only lost one mov file.
User was way over the top with excitement and gratitude.. Shame I am married :stir
A: Virus attack
B: Never write to the drive your trying to recover from
C: Do not ever run Scandisk / Chkdsk / Clean / Defrag etc on a device that your wanting to recover data from.
D: Never try to use any Recovery apps; unless you fully understand the implications and what your doing.....
D: When systems lock-up , give things time b4 removing usb devices
F: Immunise your system agents Autorun,inf and other like viruses.
Use a program like Picasa to copy off the files and take a backup and never run the memory card until it full. Always aim for 60% full at the most and then swap out and copy/backup.
Just like a coffee machine; a little house cleaning and be proactive; will see every one happy.
PS. Burnt DVD's are not ever lasting as an archive.... A few bits of lost data may not cause major picture loss, but it will render applications and other files useless.
