Bought new SanDisk Cruzer Blade 4GB USB when connect not seen in Home or any where else and no error.,

I have SanDisk Cruzer Blade 4GB USB pendrives, and they work for me

1. as mass storage devices out of the box (as delivered with one partition and fat32 file system)

2. as boot drives, when made into boot drives with several methods, see https://help.ubuntu.com/community/In...n/FromUSBStick

These USB drives have been reliable for me, but rather slow compared to Sandisk Extreme USB 3 pendrives, 5 MB/s writing speed of big files.

The hardware must be good, since you can use it in Windows. So I suspect it has a partition table or file system not compatible with linux, maybe Microsoft's exFAT file system. It is possible that Sandisk has started to deliver them like that now (my SanDisk Cruzer Blades are maybe one year old).

Try if the drive is recognized at all with some terminal window commands in blue

Code:

If the pendrive is recognized as a 'disk', you can try to re-partition and re-format it with gparted

Code:

gksudo gparted

Install gparted if not available

Code:

sudo apt-get install gparted

I have Ubuntu 12.04 LTS too. And I can see and use my pendrives of the same kind. It seems you cannot see the Sandisk Cruzer Blade device at all with Ubuntu 12.04 LTS. What do you mean by the following statement?

Tried in another Hard Disk with Ubuntu 10.04 LTS the same

Maybe there is something wrong with the computer, the USB system or that particular USB port. Try rebooting, and test all the USB ports.

Change the San Disk to a USB mass storage device. The below is from the SanDisk manual

If your player does not connect:
1.Unplug the player
2.Select Settings
3.Select System Settings
4.Select USB Mode
5.Change the USB Mode from Auto Detect to MSC
6.Plug your player back into your PC

Since your other pendrives work in this computer, but not Sandisk Cruzer Blade, there must be something new or special with that pendrive.

Unfortunately the USB systems are subject to variations, and often new versions or batches from production are only tested with the commercial operating systems, Windows and MacOS. Often the hardware will work also with Linux, but not always. You had bad luck and got a Sandisk Cruzer Blade that does not cooperate with the combination of your computer hardware and operating system, although that particular brand name, model and size (4GB) works for many other people (including me; I bought a ten-pack of them and they all work as they should in the same Ubuntu 12.04 LTS version, they are reliable but slow).
