Smile SanDisk U3 USB Flash Drive Problem
Can anyone help with figuring out how to get a SanDisk U3 USB Flash Drive to work again?

It belongs to some friends, and every time they try to use it, they get the following:

U3 Launchpad error

“An error has occurred while initializing U3 Launchpad: Drive is unavailable or unformatted. U3 Launchpad will close now. Please format the drive, disconnect the U3 device and try again.”

The drive was working fine a couple of days ago, and after some MS Automatic updates, it went belly-up!

Anyone know of a way to read or recover the contents of the drive, or any free software to do so?

Thanks in advance for the help.

Look on the SanDisk website to see if there are any updates for Launchpad.

Thanks for the reply.

Went there already, and nothing we tried worked.

Any chance of trying it on a different system?

Yep, we tried that, but it was a no-go.

Been thinking about uninstalling the U3 launchpad software, and then seeing how it goes. I think if you do that then the drive just becomes a regular USB Flash Drive without the U3 technology.

Don't know for sure, though...

I got the same problem. This arises because probably the boot sector on your drive is damaged. You can download a utility "TestDisk" from the website below

http://www.cgsecurity.org/wiki/TestDisk

Use this utility to repair your boot sector. Follow the documentation. It worked for me...

Good luck.

Thanks, Tushar!!

Will certainly give it a whirl.

Were you dealing with a SanDisk U3 USB Flash Drive?

Were you getting the following:
U3 Launchpad error



Were you able to recover the data on the drive?

Yes. I was getting the same "U3 launchpad error" ?: drive is unformatted...

I used TestDisk to get the data back (it is a free utility). This utility told me that the boot sector in the drive is damaged and it repaired the boot sector. After that I was able to see the drive and all my data as it was before the problem occurred.

Hope this is the same problem with you and you can fix it.

I have the same problem. I´ve tried TestDisk and no luck... it gives me an "write error"

tusharg, please, could you post what options you have used in that program?

Thanx

Ran Testdisk_win.exe:
  1. Disk /dev /sdf - 1019 MB /MiB was selected
  2. Partition table type: Intel/PC Partition
  3. In Analyze, the following results appear: Boot sector doesn’t have the endmark 0xAA55, bad ending cylinder (CHS and LBA do not match), no partition is bootable.
  4. In Advanced selected: Boot Sector Recovery, and obtained: A valid FAT Boot sector must be present in order to access any data, even if the partition is not bootable.
  5. Selected: Rebuild BS and received message: Extrapolated boot sector and current boot sector are different.
  6. Files can be listed, but not accessed
  7. Selected MBR Code, and then ‘Write a new copy of MBRcode to first sector’. Got write error: Cannot write MBR Code
Have no clue as to what to do next.

Any suggestions?
