Error : device not ready

[jimini24]

Hi, Sorry for my english
When I try to format USB, Ive got this error : the device is not ready
I've read your faq and you talking about bad usb connexion, it's not the case, at least for me
I solved the problem, with diskpart and automount
In a prompt, type:

diskpart
automount enable
exit

When automount is disabled, I have the error
When automount is enabled , everything is fine

So if you experience the same issue, can you please write it in your FAQ.
thanks

[pbatard]

Thanks for the tip! I'll try to add it to the FAQ, but before that, I'd like to try to reproduce the problem when automount is off, which I haven't managed to do in Windows 8.1 x64.

Would it be possible for you to send me a complete log from Rufus for when the issue occurs on your computer? Having a full log will tell me which OS as well as the name of the ISO you tried to use (or the formatting options if you didn't use an ISO).

If I could replicate the issue, I might be able to add a fix for it in a future version of Rufus, which is why the more information I can get about your system, the easier it will be for me to replicate the error and try to add a fix.

of course!

First I use diskpart and type "automount disable"
I obtain this log

When I had this issue, I didn't know my system was switch (alone?) to automount disable
so I'd try a few iso with the same issue, and didn't found the solution on google.

a few hours later I'd realize that automount was off, and so, I decide to try again rufus,

this software has almost goes to the trash for me (lol), cause it was the first time I used it

Anyway if it can help, I'm glad, and thanks for this useful software

[pbatard]

Thanks for the logs. Still haven't had any luck replicating the issue using redobackup-livecd-1.0.4.iso on Windows 8.1 x64 and with automount disable. I'll try to run some tests on Windows 7 to see if it's something specific to that OS, and if I still can't get the issue to manifest itself, I'll add a note in the FAQ.

[jimini24]

Hi, I found another reason for the issue appears.
As you can see in my previous log, the usb disk type is "fixed".That's why.

I try with a kingston "removable" disk type, it's work even with automount disable
but with "fixed" disk type and automount disable it definitly don't work.

You Can recognize an usb "removable" or "fixed" with diskpart and command "list volume".
the type (5th column) is seen as "partition", for fixed usb stick, it's like a harddrive.
for removable device dispart see type as "removable".

a good thing to know is sometimes (or always?) you can't install windows7 from a removable usb stick, but you can with one fixed, there is lot of thread about this, but few answer

Hope now you can replicate this bug and correct the FAQ

[pbatard]

Aha!
Thank you so much for following up on this and identifying the missing part.
I was also able to replicate the issue when using a fixed disk (PS: The Rufus log also tells you if a disk is seen as fixed or removable).

I'm also gonna make a note of the following issue that occurs with automount enable when trying to format a drive that didn't get formatted because of automount disable:

Format operation started

Opened drive \\.\PHYSICALDRIVE8 for write access

Invalid logical volume handle
Format error: The device handle is invalid.

I'll see what I can do to fix both these issue in a future version.
And I'll add a new entry in the FAQ about this problem when I get a chance.
Many thanks for spending time investigating this issue - it really helps!

[pbatard]

OK, I have now added an entry in the FAQ with details of the workaround:
https://github.com/pbatard/rufus/wiki/FAQ#Error_0x00000015_The_device_is_not_ready

[pbatard]

Just an addon: It looks like mountvol /e will work just as well as automount enable in diskpart. Since this is simpler, and less dangerous that asking users to run diskpart, this is what I will advise in the FAQ.
