E125 Speaker Click

Solution to CF Recorder Click Noise Problem! Hi, ever since I got my Netbook, I was annoyed about the click noise, most Netbook users hear, when recording straight to a Compact Flash Disk. Problem To test if you are suffering from this problem, make the following test: 1. Make sure you have a CF disk in D: (or E: ) 2. Start the Recorder application. 3. Select File/New File and enter any name using the drive the CF is in (D or E) 4. Make a recording, for about 10 seconds, preferably in a quiet room without saying anything. 5. Playback the recording. You will hear a clicking sound often about once every second (varies according to CF-Card used)! 6. If you hear no clicking sound and the recording sounds clean, you have no problem! Solution I have just spent a couple of days at Photokina (the world's largest photographic trade fair currently on in Cologne, Germany) visiting CF-Manufacturers with my Netbook to get to the bottom of the problem. Basically, the problem is caused by the buffer in the CF-Controller emptying faster than it is being supplied with data. This affects a lot of CF card manufacturers and the only solution (apart from recording on C) is to use a CF card with an Hitachi Controller as that is the only controller which takes account of this problem and handles the data stream correctly. I tested a number of CF-Cards at the show (only Dane-Elec refused to let me test their card) and this is the result of my hard work: CF-Cards that Work Correctly: SimpleTech (all SimpleTech CF-Cards use the Hitachi Controller) Casio (Hitachi Controller) Hitachi (of course) DataFab (the sample I tested worked, they did not know which controller) Extrememory (Some work, some do not) Note: Large CF-Cards can still have problems. Even the SimpleTech 512MB CF-Card produced the click noise whereas the 256MB card was OK! CF-Cards with Click Problem: Sandisk (incl. Ultra) Toshiba (all 3 controllers tested) Dane-Elec (not tested, but uses Toshiba controller) Those were the cards I tested. Perhaps the members of this forum can post their findings on other makes not mentioned above. I personally made the mistake of buying a Toshiba card and had no end of problems. I must say that the people at Toshiba were very helpful and let me test a range of their cards. I will now be returning my Toshiba card and ordering a CF-Card from Simpletech as the cards I tested worked well. I have no connection with any of these card manufacturers! However, I do recommend that before buying a CF card for the Netbook, from any manufacturer, you should always do the above test, first! Remember, in most cases I could only test 1 card per manufacturer so each card could differ. Test before you buy is very important in this case! I hope this helps!
