hi to all and and an early thanks to those who will try to give me a hand...

 

I created a bootable pendrive based on win2go environment on vhd file (win 10 o.s.).

 

Everything works properly until the usb drive was no longer recognized as a boot device.

 

Trying to connect the drive to another pc I noticed that it is no longer recognized.

the windows disk management tool show "no media" referred to the usb drive unit.

 

Can someone advise me how to proceed to try to solve the problem, or try to recover the data ?

Hmmm.
It might be tricky or downright impossible, that is the behaviour of a stick gone bad. :(
 
You need first thing to identify EXACTLY the USB stick.
 
Go here (use google translate from Russian):
https://www.usbdev.ru/
 
https://www.usbdev.r...icles/thestart/
 
For the moment skip item #1 (putting it in test mode which involves opening the case of the stick and shorting a few terminals and only follow #2 as to identify the chips, use all three suggestd tools:
ChipGenius
Flash Drive Information Extractor
ChipEasy
 
and report output.

It is unfortunately what I feared :ph34r:, a SanDisk.

SanDisk are (usually) very good devices but they are also the most difficult to repair/salvage because they - unlike most other USB stick manufacturers - use internally developed hardware/chips/whatever.

And an UltraFit is - I believe - a "monolith", i.e. all components are "enclosed".

More or less all you can try is their "RescuePro" software:
https://www.sandisk....flash/ultra-fit
https://www.lc-tech....cuepro/?lang=it

No idea how it works (and if will work in your case) as it is not "free" (you need to have a serial from the stick - or from SanDsk and provide personal info - BTW seemingly in clear violation of the GDPR).

it's seems a recovery tool for drive that can be yet accessed by pc.

For non funtional drives and drives that cannot be accessed by pc, sandisk reccomanded to send the drive to a third party recovery company

 

https://kb.sandisk.c...nd-flash-drives

 

 

i'll try to inform about prices for the recovery service...

From what i understand with SanDisk i don't have many alternatives...

 

Anyway, thanks for your support !

Of course it is up to you, but remember to be seated when you receive the quote for the data recovery.

We are talking of hundreds of Euro, unless you have non replaceable data on the stick, it is simply not worth it.
