Q1: Are electronics cheap in Okorder.com?
A: Of course. They are very cheap. The factories provide the goods. One-stop sourcing.
Q2: Why are electronics so cheap in ok order?
A: On ok order they are the lowest price. Because it is a wholesale website and factory provide goods.
Q3: Do all electronics have silicon in them?
A: No but most modern ones do. Older electronics that don't require micro chips don't have to have silicon at all, and their mother boards are made from copper. Silicon is used in micro chips as a semi-conductor in modern electronics but some other semi-metals, like gallium and germanium can also be used. Silicon is just the most common because it is so plentiful.

Q:how to remove write protect in card reader?
i had this problem too. theres a little switch on the side or somewhere on it, make sure it is on the unlocked position
Q:multiple SD card readers?
Yes. I had one General Electric that I bought at Home Depot in the Home Phone area, and had like 3 or 4 different drives, all read cards at the same time.
Q:Help, my card reader isn't working!?
Ours is occasionally sensitive about that card slot, too. Sometimes we think it's because, mi esposa works outside a lot and has gotten some dust on the SD card she uses on the camera. All we've figured out to do is, carefully dust off the card (canned air) before inserting; make danged sure you're inserting it right. Sometimes, pulling it out and pushing it back in, gently of course, works. Ours no longer pops up with that little window about Whadya wanna do with this carddisplay it in a browser or download pictures orDo Nothing - you know the one). We've gotta pop it in and then go to My Computer and find it as a removable disk (drive E) and then find the files If all else fails, for about $30 you can pick up a little adapter that holds the SD card and lets you slide it into a USB port. I use that to read the cards on my Mac which doesn't have a slot like our HP does.
Q:Memory card-music?? reader??
Insert your memory card in the card reader. A box will pop up that will give you some options on what you want to do with your card. Click on open folder to view files. Then copy/paste your songs into the folder.
Q:Can any mac memory card go into any mac compatible card reader?
Not sure I completely understand the question. I assume you are talking about a card reader for cards such as Secure Digital and Compact Flash. If so, your Mac can read any of these card types. The readers are pretty simple devices, usually using the USB standard. Pretty much all of them should work fine with your Mac. If this is not what you want, please give more detail and I will try to answer.
Q:how can you tell if your computer has a memory card reader?
You didnt give us the model number of your notebook. However, some notebooks now are coming out with card readers built in. (I am currently using a Medion MD42200 that has a multi card card reader built into the side of the machine) If your notebook has them they will be located on either the sides or the front of the unit. Look for slots that would fit a CF card or SD or Memory stick. If you cant find them, check the user manual for the notebook,. This will show you what ports and connections you have on your notebook as well as show you a picture of where they are located.
Q:I have no idea why my Memory Card Reader/Writer will not workCould any help please?!?
What size microSD card are you using in it? I've read some reviews that say it can't read anything over 4 gigs, despite its HC packaging claims. One more tip, in the future, when using a card reader, try it first without installing any manufacturers drivers, as most work in Windows and OSX natively. Sometimes card reader drivers actually screw up the ability for other card readers to work on that PC in the future.
Q:usb 2.0 card reader driver?
XP has built-in support for USB Flash drives and memory card readers, so you don't need any drivers. Try using another USB port or using the reader on another computer to see if the reader works correctly.
Q:SD card reader isn't recognizing my SD card, even though its lighting up?
its possible the partition information on the SD card is damaged. look into the program testdisk to see if you can repair it. if not, photorec (which comes with testdisk) can do a raw recovery of your image files. it would be a good idea to take it to a local computer repair store (one that doesn't suck, and not bestbuy) to see about recovery if its important. if the data is not, try to format the SD card and see if it works again. if you know someone with linux, try loading ubuntu live disc on your system and see if it can recognize your SD card. linux usually has an eaiser time understanding messed up data, which is why i prefer it for data recovery.
Q:Stash USB Card reader not working on Windows 7?
I don't know about the Stash brand for sure, but I had a card reader that I had to update the Firmware of the device before I could get it installed properly on Win7 64Bit. Worked fine on Vista 32Bit, but when I went to 7 it would see I plugged it in and then nothing ever popped up asking for drivers or anything - saw it in Device Manager, but nowhere else. You might try to see if there is updated firmware out there for it, not just drivers. Hope this sheds some light for you.
