Drive failure

My flash drive (San Disk Firebird 6Sp9) is no longer accessible (since this morning).  Whenever I try to access my data, I get “You need to format the disk before you can use it …”. My laptop (running windows 8.1) installed some updates when I shut down yesterday, and again when I booted up this morning, since then I have been unable to access my external drive.  I get the same error on other computers, one of which is running Windows 7. I have tried a recovery program, with no positive result. What else can I try?

 

I see the following event for Removable Disk (ESmiley Happy, Properties, Events

Re: Drive failure

What else can I try

 

I would try running a CHKDSK command on the drive,

 

CHKDSK x: /F

 

where x is the drive letter assigned to the flash drive.

Re: Drive failure

Hi Ed,

The response to CHKDSK e: /F is:

The type of the file system is RAW.

CHKDSK is not available for RAW drives.

 

Is there an alternate command for RAW drives?

 

Thanks,

Diane

Re: Drive failure

At this point if the files on the drive are important to you I recommend finding a professional service to try to recover them.  If the files are not important you can try reformating the drive or simply buying a new drive.

 

Sorry.
