They have daily backups and operate on RAID arrays, usually.I wonder how those hiQ companies manage to recover their data as if nothing happened.
If the exact spot on the disk where the data was has been overwritten you can't recover, but deleting/formatting is not overwriting remember. How much have you got back from the programs so far?Is there still a chance or godfather of a technique to get the overwritten data? Seems like my mind's corrupted. But i couldn't help asking. 'as Better posting the question than keeping it entertained.
None at all, once the physical part of the disk it was on is overwritten it is gone. Just the thing is because of disk fragmentation, there is no real relation between where a file is placed on disk and its location, so a new file could be near the start and and old one at the end.There is absolutely no chance IF the data is overwritten
I was lucky in that regard, I lost a drive that was my media one, so mostly music and video, so most of it was easily retagged. I'd sort by file size, and then think about the types of stuff you have and what sizes the files are that you made.The files are all scrambled though, they come in seperate coded folders, and it's a pain to check them one by one, and rectify if there's all the data.
RAID is a bit different to a backup, it is fully redundant storage (in some configurations), in that every single file is stored on two hard disks, so if one dies, you just continue with the other one. That also gives you double the chance of having recoverable files if you do delete.But they sometimes possess like magic tricks to recover data with no relevance to any backups however. Interesting how they do.

Last time I was involved with important backups, they were a bunch of date coded tape backups.
Utilising that external HD a bit more would be ideal, but otherwise don't mess with partitioning. You can reinstall windows over the top of the old copy, and the built in repair function of setup works wonders in my experience (and rollback has saved me many times). Make sure you have a Windows setup disk available, and I'd also strongly suggest a Linux Live CD, which would have allowed you to boot off a disc and copy files yourself over to the external drive before taking it to a computer person.
That said I'm talking as someone whose last backup is two years old (with a handful of important stuff on discs or usb drives).
There's no such thing as magic, at least not in disk storage technology. Companies, if they want to protect themselves against disk failure, employ backups and RAID. That's pretty much it. If you want more safety, make redundant backups.@sohum: Yeah mate, the backups are most genuine in every company.
