I messed up my pen drive while making it Win7 bootable

[buntygupta]

I have Sony 8Gb pen drive. I was trying to make it usb win 7 bootable drive using command prompt and messed it up.

Now I have two comps with Win and Ubuntu on it:
On win7,it shows up under disk management but not able to format.
On ubuntu i have drive disk utility, gparted, fdisk and dmesg; nothing could help to format the hard disk.
I get this message:

Welcome to the forum.

In Win7 goto the command prompt and type the following

Diskpart
Now type
List Disk (will give a list of all disks in the system), and note the drive number of your pendrive.

Now type
Select Disk (your pendrive drive number from the list disk command)
Now type the following
Clean (wait a few seconds for the pendrive to be cleaned)
Now type
Create partition primary
Now type
Active (makes the drive bootable)
Now you need to format the pendrive, so type the following.
Format fs=fat32 quick

If you need to assign the pendrive a drive letter then type the following.
Assign

Citing exactly what you did in Windows might be helpful, but from those Linux messages I'm inclined to think it's dead and would be simpler to just get a new one since they're so relatively cheap.

try vconsole.com 's USB flash drive tester. It wipes the entire drive, then read-tests it.

It generally gets rid of any strange formatting issues with the drive.

And if the drive is truely dead, then this should tell you that as well.

I tried that, but when i say clean it gives me an error stating media not found.

When you typed the "Select Disk" command, did you also enter the drive number?

Example:
Let's say the pendrive was drive number 4 (given by the "List Disk" command).

Did you then type Select Disk 4
And thereafter, did Diskpart confirm that Disk 4 had been selected before you issued the Clean command?

 

[buntygupta]

yes i did. it was select disk 2. yes it did confirm tht disk 2 selected and after that clean command did give me the error.

Run this on it, it's MS's automated install-from-usbdrive utility. It might require you to put Windows on it, but it might straighten it out and you can delete it later.
