I have a 32 GB Lacie Cookey USB flash disk that doesn't show in the Computer window but it's visible as a device.
It also appears in the Disk Management tool, but the box is empty.
Is there anything I can do or is it dead?

Looking at the Chipgenius Dump, it is a Phison Controller.
You can try the following steps one by one and check if any of them helps:
- Download Rufus or Bootice and try formatting your USB drive in Windows.
- If above step does not help, connect the USB Drive to Linux Operating System and check if you can access the files. If you can, copy your files and format the drive in Linux using Gparted or Disk Utility.
If the above two don't help, then try this: download Phison Mass Production tools for your USB Drive from http://flashboot.ru/files/phison/ and try formatting your USB Drive. You will have to try with each tool until you succeed. This tool will try to reprogram your USB Drive's Microcontroller and format it again. NOTE - This will delete all the files in your USB Drive.

Hope this helps. Let me know how it goes.
Do you have the proprietary driver software installed? This should be it: http://www.lacie.com/support/drivers/driver.htm?id=10253
Also, make sure Windows update isn't automatically replacing it with the default 'Mass Storage Device' driver.

P FitzP FitzI tried everything, I mean everything. Finally I downloaded Jetflash application above and it actually worked and saved myself a 16GB memory stick.
When there is a “No Media” error message, it basically means that the USB flash drive isn’t in full contact with the USB socket. Sometimes the USB access/power light may come on even when there isn’t full contact on the two D+ and D- pins, or pin 2 and 3 of the A connector.
Try the drive in another USB socket, a USB hub, or use a USB extender cable. A USB extender cable usually lets you see if the 2 holes on the sides of the type A male connector mate completely with the 2 fingers on the female type A socket.
When the USB connector and socket mate completely the USB flash drive should appear.

I have a USB flash drive which is no longer recognized by my computer. Windows Disk Management and DiskPart report No Media with no storage space (0 bytes) on the drive and I cannot partition or format the drive:

If the drive appears in Windows Explorer, trying to access it returns an error message indicating that there is no disk inserted, such as the following:

However, the cost will increase if Apple Inc. Wants to increase the number of products that they wish the manufacturing partners to produce or vice versa. This cost is considered as variable cost. 3/ RESEARCH AND DEVELOPMENT According to its latest earnings report, Apple spent about $1.18 billion on Research and Development.

Various disk partitioning and data recovery utilities don't recognize the drive or only give a generic name for the drive and cannot access the contents of the drive.
What can I do? How do I recover data from the drive?
This question comes up often and the answers are usually the same. This post is meant to provide a definitive, canonical answer for this problem. Feel free to edit the answer to add additional details.

Failing Flash Drive
'No Media' means the flash memory controller cannot communicate with the NAND flash memory on the drive. Because of this, it appears to the computer as an empty disk drive. This is usually caused by the NAND flash failing. To the computer, the drive is not much different than a floppy or optical drive with no disk inserted.
As a result, it is not possible to access any data on the drive, nor is it possible to repartition or reformat the drive. Again, from the standpoint of the computer, there is no medium in the drive to be formatted or repartitioned.
Fake Drive?
It is also possible that the drive is fake and the cheap memory chip in the drive has failed. Drives failing in this manner will often show up as a storage device with 8MB capacity.
Potential Hardware-Specific Restoration
From this answer: You can obtain more information about the drive and its controller using a tool called ChipGenius. You might be able to recover the drive hardware by using a tool such as Bootice to manipulate the MBR.
Additionally, if the drive uses a Phison controller, you may be able to use the Phison USB Mass Production Tools to reprogram the controller and restore normal operation. Note that doing this will erase all data on the drive.
Data Recovery
In cases where stored information is merely corrupted, consumer data recovery software can often recover the contents. However, that won't work if the drive fails as described here.
There are data recovery services that can use special equipment to try to recover content from the chips. However, it is expensive. If you can't restore the drive to normal operation, it probably isn't worth sending it to a data recovery service unless the data stored on the drive is particularly valuable. You should simply replace the drive.
bwDracobwDracoGo to MyComputer/Manage/USB Controller/USB Mass Storage/Unistall while plugged, then remove it, and re-plug in, the driver will -re-installed. It solved it on my computer.
This may happen also when there is insufficient power supply to the flash from the usb port. Check that you are not overloading the usb ports with power hungry peripheralas. Also tortured USB cables, if there are any connected, may sometimes leak current and reduce the available power.
The flash drive is fried, or at least not functioning. I did this to save the content: put it in the freezer for a couple of hours, and it appeared again for just enough time to copy the contents to the harddrive. Then it disappeared again.
