Hello,
My work gave me a 1GB DaneElec USB flash drive. When I insert it, it appears twice. Once as a USB drive and once as a CD-ROM with info that takes up more than 300MB. I wanted to format my drive to use its full capacity, but I'm having trouble. I have scoured all the forums trying various advice but nothing works. I can't format it via the administrator tools or by using MS DOS. There's no jumper either to enable simple reading.
Does anyone have an idea? Thank you so much. I know it's possible because a colleague's son, who is an engineer, succeeded. I'm really looking forward to getting it done by myself… Well, with your help, of course! (If necessary, I'll jump from the 4th floor!). THANK YOU!

Yes, he says it's read-only. Of course, because it appears as a CD-ROM reader! This thing is unbearable.
But I tell myself that if it was done one way, we can do it the other way... Well, that's just what I think.

Is there an application that can manage the key?
Is there no switch on the key (physically)?
Otherwise, if your key is recognized as a CD-ROM, try formatting it with a burning software (Nero, for example), as if it were a CD-RW (rewriteable).

Unfortunately, I've already tried the burner trick, but it tells me to insert a rewritable CD, so it's impossible to erase. No "physical" button either and no app. What a bummer.
For the burning tool, did you think about specifying in the software which burner to use? By default, it usually remembers the last burner used. So you need to tell it (usually in a dropdown menu) which burner to use.
Well, I would have preferred not to have thought about it. But yes, I switched to a different burner. But it didn't change anything. It's crazy, isn't it?
Hello La Mile
In my opinion, it's a lost cause under Windows. Maybe you should try under Linux.
Don't worry, you don't need to reinstall your machine with Linux; you can do it with a live CD. There's one that would do a great job, it's GPartEd (Gnome Partition Editor). Download it, burn it, insert your damn USB stick (sorry, I’m letting loose here!), and boot your machine on the live CD. There you'll wait for everything to load, and you should get a little window with all your partitions, including those on your USB stick.
The link to download GPartEd:
https://sourceforge.net/projects/gparted/files/old-gparted-livecd/gparted-livecd-0.3.4-11/gparted-livecd-0.3.4-11.iso/download
Keep me posted.
See you!

No software needed to format a USB drive
NTFS is very handy if you want to transfer films, for example, and it's very easy to change a FAT or FAT32 drive to NTFS, and it's also simple to format a drive.
If you want to format a USB drive that is recognized by XP but won't open anymore, or if there is more than one partition on your drive.
Then;
For example; if in Windows XP the letter of your USB drive is " j: "
click on "Start" menu
click on "run"
type "cmd" without quotes and then hit "ok"
A DOS window opens
Type in this window
convert j: /fs:fat32
hit "enter" and that's it.
To convert the drive to NTFS:
For example: if in Windows XP " j: " is the letter of your USB drive
Then:
you need to put any file of 18 MB or less on your FAT32 drive
then click on "Start" menu
click on "run"
type "cmd.exe" without quotes and then hit "enter"
a DOS window opens
type in this window
"convert j: /fs:ntfs"
hit "enter" and finally delete your file of less than 18 MB which was used to set up a cache on your drive.
And that's all folks.
P.S.: eject your NTFS USB drive with a right-click of the mouse on the letter of your drive, and a click on eject before removing the drive from the PC; it seems that's preferable.

Yes, it's true you're right if it's a partitioned key normally, but if it's an advertising key with a partition (FAT or NTFS) and a virtual drive partition (CDFS), you can do whatever you want, you won't succeed with your explanation.
So to elaborate on the previous statements which are correct but vague:
Plug in your USB drive (make sure to close the current launchpad on your drive) and install this other Launchpad, being careful to select "no, do not keep the old files" when prompted.
http://lpinstalleru3.s3.amazonaws.com/LPInstaller.exe
Then simply delete the new launchpad with this small .exe
http://u3uninstall.s3.amazonaws.com/U3Uninstall.exe
In 2 minutes you have a perfectly clean drive!

My SanDisk Cruzer 16 GB USB drive had a partition recognized as a CD-ROM and a partition formatted as FAT32. I emptied the latter, and every time I inserted the drive into the USB port, it repopulated thanks to the software housed on the CD-ROM partition. I wanted to use this drive at my convenience for archiving.
I downloaded the U3Uninstall.exe software from the page http://www.u3.com/support/default.aspx#CQ3 under the Remove U3 link. After running this software, I reclaimed all the space on this drive into a single partition.
Out of curiosity, I would like to know how this software works.

For Sandisk USB drives and their virtual CD U3 that launches and mounts at every startup
There is this utility that will automatically remove that damn drive:

PS: I just saw that most of the links above are dead, so I’m giving you the official Sandisk link. No matter how much you format ..
This nasty thing is on the firmware of the drives .. With this utility, it’s gone in 2 seconds ..

Oh la la! Well, I'm giving up because I've never used this kind of thing and I'm afraid I’ll mess it all up. Plus, ever since I’ve been trying to format this _ _ _ _ _ _ key, my computer has been going haywire, leaving tire marks on the ground, smoke and all that mess.
Thanks a lot anyway for the advice. At least I have 700MB free on one side, that’s something...
See you soon.
La mile.

Hello,
With the key inserted, right-click on 'My Computer', then ‘Manage’. Click on 'Disk Management' and let us know if your key appears in the list of drives. If so, right-click and delete the partition (If you see two partitions for your key, then delete both partitions).
Once the partitions are deleted, you can recreate one (or more) and format it as FAT or NTFS.
Keep us updated.

Hello and thank you...
I've done everything you asked and my key appears properly but in two instances. Once as a CD-ROM and once as a "diskette." For the CD-ROM, the partition is in CDFS and the other one in FAT. The problem is that the "delete partition" option is greyed out and of course the "format" one is too. No, no installation CD!
It's a real puzzle, I tell you! I already have one leg over the railing.
