Just updated the firmware & realtime clock library.

After compiled my program, I want to save to mbed, the following message showed :

Disk is not formatted

The disk in drive E is not formatted.

Do you want to format now ?

answer : yes ==>

Format Removable Disk ( E:)
There is no disk in Drive E

Insert a disk , then try again
press 'OK" ==>
The disk in drive E cannot be formatted.

press 'OK' ===>

Save as on the PC desktop screen showed up.

HELP !!!

What should I do ? and
What did I do wrong ?

Hi,

After compiled my program, I want to save to mbed, the following message showed :

Disk is not formatted

The disk in drive E is not formatted.

Do you want to format now ?

answer : yes ==>

Format Removable Disk ( E:) 
There is no disk in Drive E

This suggests the computer can see the mbed, but that the drive itself is not visible.

I assume you've been using it successfully up until now? So could you potentially be running a binary that accesses the local filesystem, and hence "removes" the disk? For example, if you open a file, but never close it, you'll not ever see the disk until the program ends or you reset.

If you press and hold down reset, that will ensure no program is running. Does the disk then re-appear (may take a second or two)? If so, you can hold down reset, and just delete the binary that is misbehaving.

If not, it might be useful to have a little more info about the setup (OS etc), and what happened leading up to this (e.g. what was the last binary you downloaded etc).

Thanks,

Simon

Thanks.

Indeed, when held reset key down, the drive appeared.

It's fixed. I erased all the files and started all over again.
