A disk read error occurred

My five and half years quad core desktop started giving me a lot of disk errors in the last year.

It was like once a month in the beginning till unbearable once a week.

Some times the harddisk just disappear from the system.

I got A disk read error occurred error when I restarted it. Harddisk SMART Status may show  BAD.

I changed the SATA cable. Didn’t help. Suspect it was my harddisk.

Took the oppotunity to upgrade to a new SSD. Didn’t help either.

Did almost all solutions mentioned in this post, no success.


Until recently I realize it might be the SATA socket on the motherboard.

After a few swaps, I found two SATA sockets on my motherboard had gone bad.

Currently my SSD stays stable on SATA 3 on the board for more than a month. Hope it can keep strong until Intel produce something worth upgrading.

Classical recording shopping in Singapore

With the closing down of HMV@313 Someset, I no longer visit any local store for classical music recordings. Instead I now fully rely on online store for physical release, spotify for streaming and of course live concerts for the real thing. I’m not a fan for download.

Just to share my experience on shopping/collecting classical music. I purchase most of my recordings from following sites:




The above three sites have the best shipping rate to Singapore.

Occasionally I would also buy from



For physical stores, you can also try shops in Adelphi, there are a few that carry oops release at reasonable price. These shops are serving towards the “audiophile” crowd. I seldom visit for classical new release.

Besides HMV@Marina Square (Update 2015, closed). The other surviving chain store is That CD shop.


In fact it was transformed to focus on cafe more than on CD. I haven’t tried their food. Maybe next time, as I guess their cafes have a much higher chance surviving than the CD outlets.

Physical recordings have become collection item rather than the main stream music carrier. Nothing wrong with it. You just need to know the trade off.

Update: That CD shop in Raffles City closed. Check their facebook for the latest branch info.






1. CPU长期被占用,唤醒

2. 3G/4G数据连接一直被占用。




1. 把微信所有提醒功能,没用的插件关闭,自己手动刷。毕竟需要即时联系我的人,不会用微信。

2. 安装 2 Battery 或者 JuiceDefender, 这两个app能阻止其他app后台一直连接数据。



Android 系统支持完全的多任务,后台app可以用wakelock来推迟CPU进入深度睡眠,来完成一些任务。如果app设计得当,完全没问题。但是一些垃圾app, 有事没事发wakelock。你想象一下,半夜每几分钟被人推醒一次的感受。

微信因为某些原因,采取了令人发指的后台自启动,唤醒CPU设计。即使把所有更新都关掉也一样。不管你有没有root,安装 BetterBatteryStatus 或者 Wakelock Detector,你就可以看到微信WeChat的唤醒次数。


于是我用Advanced Task Manager 每10分钟杀一次WeChat进程。实际上每次杀WeChat,它会自启动,所以必须反复杀。但间隔太短也不行,毕竟杀进程本身就要占用CPU。



Update: 貌似5.3改变了不小,有待继续观察 

Spotify user report in Singapore

Have been using Spotify as my main streaming service for both classical and pop/rock/indie music for a while. Just like to share with you my experience here. And you can judge whether you wanna give it a try or even pay for it. I’m not going into discussion how spotfiy is paying the musicians here.

This report is based on both PC and Android versions.

1. One of the biggest streaming provider, legal, free (at least for basic service).
2. PC version is totally user friendly.
3. The premium account charge of $10 per month is also reasonable. I’m assuming you would agree that one month of music streaming service should be more valuable than two cups of mediocre Starbucks coffee.

Mobile version still lacks some key feature.
1. For free account, you can only shuffle play a playlist. If the playlist contains only a few tracks (e.g. a symphony), spotfiy will insert other tracks they think you would like (so far i find their recommendation pretty poor..)

Some smart guy would suggest use the skip button for this. The spotify guys are not dumb either. They set a 6 skips per hour rule on the free mobile account.

I know you’ll be really be pissed off when you were listening to some great rock, suddenly one of the “boring” Bach’s cantatas was inserted (this is purely fictional, I have not experienced classical inserted into pop/rock listening session. Btw, isn’t that a good way to raise the awareness of classical music?)
Vice vesa, when you were listening to the St. Matthew’s Passion, you will certainly be annoyed when some crap pop popped up.

2. Another key feature lacking in mobile app is that there is no way to find out which musicians you are following. Everytime you need to search the entire spotify database.

Update: this has been rectified in the latest version.

3. Apart from that, when data connection lost, you can’t playback the cached tracks you just listened. I find this more useful feature than having to preload the offline tracks.


Spotify uses Ogg Vorbis as encoding format, which is a fine choice. Even though it is not as great as what I would like to have DTS Headphone:X. (Disclaimer: I work for DTS.)

Another thing I really hope Spotify could do is to launch their premium service together with Singtel. Such that the data charge can be free or at least much more than the plan package quota. I feel my 3GB monthly quota not able to keep up if I were to use Spotify as my sole mobile music service. I know that would mean Singtel have to kill their own AMPed which I have yet heard a good report.

Before all these being fixed, I’ll be still paying my naxos.com subscription, they’re even cheaper than spotify and also cover a pretty wide repertoire for classical music.

Darkness in Light

Last Friday, I attended a concert by Singapore Symphony Orchestra (SSO) in esplanade concert hall. The title of this post actually comes from the concert.

It is also the name of the violin concerto composed by Finnish composer Sebastian Fagerlund.

One interesting fact of the concert is that, this was the first time I heard both the conductor and soloist performed in the orchestra (besides conducting and playing as a soloist). Conductor Vanska played clarinet in the opening piece, while violinist Pekka Kuusisto joined in the violin section in the second half.

The concert openned with Dvorak’s Serenade in D minor, which is certainly not a standard piece in concert programme. In fact, this was the first time I heard it. It’s always good to hear some thing new. But to be honest, I find the color tone a bit strange. Most of the time, oboe was the only instrument on high register, and sounded floating out of the otherwise bass dominated ensemble (bassoon, horn, cello, double bass).

The Asian premiere of Fagerlund’s Violin Concerto turned out to be a rather interesting piece. I particular like the slow movement. There happens to be a great recording on youtube by Finnish Radio Symphony Orchestra and the same soloist Friday, Pekka Kuusisto. You can find out yourself here.

The main attraction of the concert for me was Sibelius’ Symphony No.5 in the second half. Having heard both Vanska’s recordings with Lahti Symphony and Minnesota Orchestra on BIS label. I was eager to find out how it worked out with SSO. The performance sounded generally fine, apart from some minor late entry of section in the beginning. I would also like the woodwind sounded a bit “colder” or more distinct from the string section. This is Scandinavian music, right?
The audience broke into applause after the first movement. You can tell this applause was sincere rather than inappropriate.

On my way back home, I chatted with my friend in SSO who played in the concert just now. When I told him Vanska just resigned from Minnesota Orchestra, which has locked out its musicians and cancelled the entire 2012-2013 season and ongoing. His reply was rather simple and true: whenever economy worsen, arts suffer the first.

When most people had to make a choice between bread and music, the answer would be apparent. Even though I skipped my dinner for the concert, I have to make sure my family were well fed. I play my part in supporting the music community by purchasing music live or recorded, from rock/pop to classical. Over the past 10+ years, the money I spend on music can easily pay me a car, say Volkswagen Golf (not in Singapore with the current COE..). However most people today expect music to be free. Many artists were forced to become “entertainer” and many many f**king boring “artists” jumped on to the stage to “entertain” the mindless audience.

I guess I should stop here. This is Darkness in light, happening now in this world we’re living in. If you were not yet bored with what I wrote here, read on what happened to Minnesota Orchestra and listen to the swan song of the Minnesota Orchestra. I hope this never happen to the city where I choose to live.

Canon EOS M for Travel

When EOS M was first released, I was a bit skeptical about Canon’s plan. The following EOS 100D somewhat confirmed my hypothesis. Canon certainly doesn’t want EOS M to hurt its own financially succesful EOS xxxD (or Rebel/Kiss) series. On the other hand, mirrorless systems from other firms had pushed Canon hard into developing it’s own mirrorless system.

Due to the reason above, on paper the late to party EOS M is not as exciting as some of the other firms’ offerings. However, choosing APS-C size sensor, excellent EF M lenses and seamless integration with Canon’s DSLR system, EOS M has always be on my radar.

For casual snap, I’m happy with my HTC One XL. And my Canon EOS 40D DSLR still serves me right after five years. There was no strong attraction for me to adding a mirrorless system. It wasn’t until the following two events happened, i decided to take a serious look at EOS M again.

1. I planned for a travel to Perth, west Australia. And I wanted a more relax trip. DSLR togather with the lenses are just a bit bulky.

(Don’t be fooled by anyone who told you that a bit more exercises and a little more time in the gym would make your DSLR system lighter. Try yourself and judge. I finished seven full marathons in past years and could lift 100KGs weight. I don’t find DSLR with lenses light by any mean when on travel)

2. The week before I bought the EOS M, I learned the news a new firmware which would significantly improve the AF was soon to be released for EOS M. What’s more, a new EF M 11-22 would reach the market right before I headed out to the desert in Perth.

The following weekend I purchased the system with EOS M + EF M 18-55 + EF M 22 + adaptor + 90EX + leather jacket (you need it to improve the poor grip) for just a little more than S$800 (after selling a free gift EFS 55-250). This is cheaper than what I paid for some of my DSLR lenses. I don’t think any other mirrorless systems can compete at this price or even higher. If minus the price for lenses, adaptor and flash (all these keep much of their value after years), the EOS M body only cost me about S$50. Even my home affair minister was supportive of the purchase plan…

The EF M lenses:

By now, I have all the three lenses available. They are all nicely built both mechanically and optical wise. Each of them seems to be among the best of the class. All three lenses are very affordable too compard to other firm or Canon’s own DSLR lense with same quality. I sold my Sigma 10-20 before I got my EF M 11-22.

The fact is, all three lens performs better than the EF S counter parts probably due to the flange distance and focal length. My future plan is to use EF M for ultrawide, wide zoom and prime. My DSLR would deal with the >=40mm primes and tele zoom.

Before getting my hands on the EOS M, I thought I would be using the 18-55 for most of casual shoot. I was wrong. The lovely EF M 22/F2 was almost full time attached to the M. It was only during the Perth trip, 18-55 started to take the main role. I only used the EF M 22/F2 indoor and at night during the trip.

Here are some of the photos I took during the trip

Here are some of the TIPS that may help cover M’s weakness compared to a DSLR during your trip:

1. Get THREE batteries. One major complain about EOS M or mirrorless cameras in general is the battery life. 3 batteries should serve most people right. I usually end up using 1.5 batteries during a day. 3 is on my safe side, and I don’t need to charge every battery every night.

2. Get a cap (for yourself), it helps block out some sun light while you shoot outdoor.

3. Setting up the EOS M while you’re on the tour bus or you asked your wife/partner to handle the camera while you were driving: This is what I did, Tv mode 1/1000, ISO auto up to 3200, AF multi-zone autofocus, always shoot in raw.

4. If you shoot in Av mode, you can trust the metering system on EOS M when you can’t really use the LCD as a reference for exposure. Of course, you still have to adjust the exposure compensation according to the scene.

[Update] 5. Secure your Sunglasses while composing outdoor in strong sunshine. I lost a pair of mine during one of my travels..


EOS M is far from perfect. but remember I told you it costs only $50. If you’re not happy with a $50 mirrorless, there are other options from Sony or Olympus or Panasonic, or you can also wait for the EOS M mark II.

[Update] EOS M mark II was released. Knowing the Canon way, I thing Mark IV sounds a better upgrade..

I would say it is great for travel and daily use. For more serious tasks, just pull out your DSLR or whatever you’re happy with.
