It’s been a fun week - trip to Bombay, meeting with old friends, a cousin coming over - basically, the works.
The thing is, my cousin (Rishi) got the phone he uses in the States over here. The only network that it managed to recognize with the original sim card in it was AirTel. Touble is international roaming costs a ton. Pretty obviously, Rishi wanted out. Usually, when friends come over from international territories, they simply buy a local sim and use it till they go back. Unfortunately, any sim other than the original one gave an invalid sim error. A quick search on the net revealed that it’s a sim locking system implemented by the provider. Of course, there were also a lot of links on how the lock could be broken - for a price, but we weren’t interested. A call to the service centre revealed that they could also break the lock for INR 1000/- (appx USD 25), but Rishi wasn’t very keen on tampering with the phone. Then we had a brainwave. If the original card showed an AirTel signal when inserted, would a local AirTel card work on the phone? It did. We could make and receive calls without any trouble. So all you guys out there with phones purchased from the providers - come to India and get an AirTel card.
When I went to Bombay, I was hanging out at a friend’s house. He was trying to back up some of his data on a DVD - and we were supposed to leave for dinner in some time. I was wondering why he was in such a rush to burn the data. On a 8X writer, a complete disk burn takes approximately 8-8.5 minutes. When I asked him I was informed that his burner took 54 minutes to write a DVD. I was pretty shocked. Initially I thought that there was a problem with his SATA drive and the DVD writing, but somehow that theory did not gel. The next thing I thought of checking was the IDE cable settings for the Primary and Secondary channels. The primary channel was fine. However, the secondary channel - which incidentally his DVD-ROM was connected on was using PIO mode. For those born after this mode, PIO is one of the slowest modes of data transfer, and has been replaced by Direct Memory Access (DMA) and Ultra DMA (UDMA). There was an option to use DMA - if available. A change to this setting and a restart left the system setting unchanged. A quick search gave us the dirt. It seems that if in the data transfer the OS encounters more than 6 CRC errors, it switches the system from DMA/UDMA to PIO mode in order to “protect” the user.
The workaround :
1) Go to System -> Hardware -> Device Manager -> IDE/ATAPI Controllers
2) Delete the channel (primary and/or secondary) driver
2) Restart
3) Set the mode to DMA (if available) and restart the system.
This should fix the problem in most cases. Once we did this, the system started burning DVDs in 8 mins and 49 seconds.
The last few days have brought terrorist bombings back into the front pages. In India, we managed to stave off a militant attack on the disputed land at Ayodhya and the London transport system was systematically bombed by terrorists. The only thing that comes to my mind is a saying by Mahatma Gandi - “An eye for an eye makes the whole world blind.”
Give peace a chance..
