Benefit of Disk caching?

Asked by shruti in Computers & Accessories at 9:03 PM on July 03, 2008

alok's Answer

If the cache controller never fails to write to disk what has been entrusted to it (even if the keyboard sticks, the operating system crashes, or the hard disk crashes), there will be no problem. On the other hand, if the disk controller delays the writing of some SQL Server log data and chooses to physically apply other log data (because of the "elevator" sorting) and fails to write the rest of it for some reason, SQL Server has no way of knowing that some of the log is missing. A warm start or even rolling forward from a snapshot backup might not restore the database correctly. In the worst case, there would be no failure during recovery and data corruption would be discovered much later.

Blue screen of death? What to do?

Asked by shruti in Computers & Accessories at 9:03 PM on July 03, 2008

alok's Answer

You've really never seen one?
It does not say blue screen of death.
The "BSOD" means that a program has crashed and Windows is going to crash too.
The screen is all blue with white lettering. The error message will be different depending on what caused the computer to crash. It will inform you that you can press Ctrl-Alt-Delete to reboot the computer.
The best thing to do whenever you see this screen is to restart the computer. Even if the computer will successfully salvage the situation it doesn't usually work right until you reboot.
Consider yourself fortunate if you don't have to see this screen very often. That means that your computer isn't very crashy.

Portable hard disk lifespan?

Asked by sachin in Computers & Accessories at 9:04 PM on July 03, 2008

alok's Answer

Because a portable hard disk is in an enclosure it gets hotter than when it is mounted in the pc. So it can decrease the lifespan. I bought a 500gb external drive and used it for backups and it died in 3 months
