Let’s start it off with RAID. I have never written about RAID before on Hacker’s Lane. So in this post, I will be explaining about RAID, and it’s types. Plus, I will be pointing you to a site where you can calculate various aspects of a RAID. :)
What is RAID?
RAID stands for Redundant Array of Independent Disks. Put in simple words, it is “A bunch of harddisks connected together“. The drives present in the RAID array are called “RAID Members“.
There are many softwares out there that claim to gather info about your system. CPU-Z is one of these, and is so far the best of all that I have used. The thing I like about it is that it isn’t motherboard board specific unlike others. You can install it on any Windows-based PC and get a deep insight of your system within moments! (more…)
In Windows, some files, mostly system files and viruses have a bad habit of not getting deleted easily. You have to close “explorer.exe” and then delete them through “cmd.exe”, and sometimes even that doesn’t helps!
These files mostly give out these errors when you attempt to delete them:
Cannot delete folder: It is being used by another person or program
Cannot delete file: Access is denied
Make sure the disk is not full or write-protected and that the file is not currently in use.
The source or destination file may be in use.
There has been a sharing violation.
The file is in use by another program or user. (more…)
