Lexar Professional High-Speed 1GB Secure Digital Memory Card - Answered Questions & Fixed issues

insert it in your pc.
right click after it appears on your computer. and click format or erase.
if these options are not available, delete everything from it.

To connect the SD memory card to the computer you need a USB memory card reader. Plug the SD memory card into the USB card reader and then plug the card reader into the computer's USB port.
The computer will see this as an external memory card, you can then click on this memory card (it maybe the D or E or F drive) and select the music files from your computer then copy and paste your music files to this memory card. I presume the music files you need to copy are MP3 or MP4 files.

you can download music using a program like limewire.
limewire.com i think is the website. then copy them to the sd card.

(you may have to get a sd card reader for your computer if you don't got one so you can buy pass your camera completely)

check whether u have installed USB controllers & drivers.
If nothing happens then do this. go to Start--> Run and type "devmgmt.msc" without quotes and enter. Then device manager will open , now connect ur memory card and look for scan for hardware changes menu . click that and scan . now u will find if any new hardware components are fixed to your computer or not. Then your memory card will be detected.

Honestly, it is most likely a defective memory card or not compatible with your camera. Sorry.

You may need Administrator privileges on your computer. Plug in flash-drive. Allow time for Windows Explorer to read it. Run AV scan if suspect. To get a list of attributes: Launch Start > Run > CMD. From the command console enter attrib F: (or whatever the drive letter is for your flash). to redirect output to a text file enter (example) attrib f:>%homepath%\flashatb.txt From the list you should see [H]idden, [S]ystem or [R]ead only attributes for write-protected files. You can also do it via Win Explorer by right-clicking the drive icon. Remove all above attributes. As a last resort, you can full-format the entire flash via explorer. Which should wipe all files / folders on the drive.

does the card contain important data? if not would formating it help? have you a computer you could plug the sd card into and see what windows makes of it? http://en-americas-support.nintendo.com/app/answers/detail/a_id/452/~/general-sd-card-and-microsd-card-troubleshooting check nintendo site and see if that helps.

There is a little tab on that unit that slides back and forth. If the tab is missing, you need to use a piece of scotch tape to simulate the tab.

plug the flash drive into a usb port it will register on the desktop and will be recognized in the computer and given a designation--- example:- drive h--- select what you want and save as --in h or copy /paste to h or if you have 2 screens click and drag to h in the computer section of the second screen

Either there's a little switch on the side, or the card has failed.

SD cards have a slide switch along one edge. The position farthest from the metal contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card.

Once the device is recognized by your computer, locate the icon for the drive and select it, right click and scroll down to the format option on the context menu. Be sure you don't format over a drive that has necessary files as formatting will erase all files on the drive. Choose the appropriate format for the system it will be used on.....Windows, Linux, Apple etc.... Often you will have other options, such as Quick Format (most appropriate) or Complete and Utterly Long Format (which - as you might infer - takes for freakin' ever!)

If using Windows system on a computer: Click start, then Computer then find the USB thumb drive you want to format, right click on the drive and then click on "Format" on the dialog box that appears.

Just plug it in and it should be recognized by Windows and assigned a drive letter.

Try this: Go to Start, right click on My Computer, select manage. In the left pane click device manager, scroll to Universal Serial Bus Controllers. Delete all of them. System may not allow some to delete, thats fine just delete all that it will allow. Then leave your usb connected to the PC and reboot. OS will reinstall all usb drivers on its own, and it may then see your stick.

You can try using a file recovery software like Bad Copy Pro 4.10.125. It works well for me.

Try http://www.apple.com/macbook-pro/ You most likely will need a different card to be compatible with your MacBook pro. Apple website should be helpful.

you just try to add files more than 142 mb if it goes smoothly then add files up to 4 gb and then again format it in other device
