1GB Toshiba Flashdrive can no longer be read by my PC

To answer your question, no. Those RAM types are not compatible as they are a full generation apart in terms of a RAM lifecycle.
And to answer your question about Readyboost, no. Installing a 1gb flash drive to use with readyboost isn't the same as installing an extra 1gb of internal system memory. It essentially allows Windows to use the newly added flash drive as a system cache. See more information on Readyboost here.
Thanks, and have a great day!

try to read flash on another system if it reads ok, problem is with your sytem if not reading needs to be formatted and should work ok.

If Toshiba says 1GB then they will be right

Try reading this it is quite clear

Try getting your recovery DVD's out --- put Disk 1 into the drive; choose "Install Applications and drivers" --- click Next and follow the directions.

------------------------- Hope this helped you.

no its not the problem with your vista , its the problem with usb flash drive, sometimes your antivirus program prevent it from reading the flashdrive because of some virus on it.

two things to do.

1. Go to your system manager, then hardware option. If you can 'see' that drive(listed under DVD/CD) then it's mechanically ok.

2. Drivers for these can be abrupted quite a bit, easily. Check for drivers at support.toshiba.com

unfortunately the files cannot be recovered immediately, macs a are compatible with PC flash drives but not the other way around. you need to format the disk. go to start>my computer> then right click on the flash drive and then left click on format, then click ok. when it is done bring the flash drive back to the mac and put the files back on. now try putting the flash drive into the pc again
