A user came the other day with a notebook running Windows7 Home edition. He asked me if we could recover the login password. The first thing (as I normally did) is to google for “recover windows 7 password”. Among the first page entries, was this website: http://pcsupport.about.com/od/toolsofthetrade/tp/passrecovery.htm – a list of “Top 6 Free Windows Password Recovery Tools”, then I remember I did used one of the tools last time to recover windows2000 login password, which is “Offline NT Password & Registry Editor, Bootdisk / CD” – http://www.pogostick.net/~pnh/ntpasswd/bootdisk.html

Here are the procedure/steps that I used to fix the “famous” Seagate 7200.11 BSY problem, I had a few errors while executing the procedure, and manage to successfully recover the Seagate HDD – Hope the problem and workaround that I use can help other who might faced the same error.

A little introduction of this problem can be found widely on the internet – Google for “Seagate 7200.11 BSY”. There are two types of problem, one is the 0 LBA error where the BIOS still recognize the HDD but with 0MB drive, while the other one is the BSY error, where the HDD stuck in BUSY state (hence BSY) – In this state, the BIOS will not recognize the HDD anymore.

In our case, we have one Seagate ST3500620AS 500GB hit by the BSY error, to make things worst it’s an OEM drive installed in the HP IQ508D TouchSmart PC – so no direct support from Seagate and HP will just replace the HDD with a new one. Unfortunately we need the data from the Seagate HDD, so I started searching the internet for the solution (and yes we have to buy the “faulty” HDD from HP in order to keep and recover the data).

At the office, we are using the Symantec Endpoint Protection (corporate edition) anti-virus solution. One day we realise that every computers running Windows XP Professional in the office is having an issue with low disk space. After a details check-up we found out that the Symantec is storing all the virus definition updates in the “C:\Program Files\Common Files\Symantec Shared\VirusDefs\” folder and it will never gets deleted ! most computers will have at least 20-40GB alone in that folder. The workaround is by using this simple MSDOS batch file to actually delete all the TMP files in that folder.

The situation is you have a number of files with sequence filenames, and you would like to rename it, for example you would like to rename from photos01a.jpg to photos01.jpg, yes, it just a simple removing the ‘a’ from it, but it would be an annoying jobs if the number of files is quite big.

sed stand for Stream EDitor. It is more to ascii text manipulation, but this time while it’s from the command line instead of in the text editor like vi. The replace command looks exactly as the vi editor replace command.

Been long time since I used this command, only today I had a chance to try it again, and to my surprise it still works ! Previously I use this under SUN Solaris unix, it still works when I tested it on FreeBSD 5.x.

In windows environment you will just have to open the search window, input what you want to search/find and then click the search button. In unix/linux environment, if you’re using the X windows system, you might have that capability, but for a faster action, I always prefer the terminal/shell prompt.

Links is a way to replicate a file and share it with other users (of course with a proper permission applied). Any changes made to any of the link files, all will be affected. This was used last time during software programming development on unix (and yes that will be >10 years ago, vi is the best editor and cobol was widely used).

Another looping command that you can use in command prompt is while loop. Used to be my favourite while waiting for some process to finish – usage to monitor that on-going process, as I hate waiting without knowing whats going on – eg. how much records has been transferred etc. etc.
