USB stick not accessible

[joachim]

After recording from a SAT receiver until the stick was full the stick is no longer working. With Linux no device is showing. Under Windows the drive letter is showing but no access (no chkdsk, format etc). Even a low level format prog is not working (no access). What can I do to get the stick working again (32GB)?

Thanks for help

Are there any messages in dmesg when you plug the stick in?

More information would be good

What format the USB Stick is in?
What Brand / Size?

What SAT Receiver?

 

[mcobit]

SAT receivers and tvs tend to reformat a usb device as they record in a drm format with a linux filesystem like zfs.


Can you read the stick with the receiver?

 

[comradekingu]

Is the stick by any chance a very cheap knockoff one?

"lsblk" "df -h" anything?

 

[rohezal]

Is ntfs supported by the Pandroa?

Is ntfs supported by the Pandroa?

If you install the codec pack it is.

Wow, that was a quick response. Here some more info. The stick is from a friend, I don't know the brand of the Sat receiver. lsblk and df are not showing the stick which is Intenso 32 GB. A second with FAT is working without problems. Maybe its the zfs file system. My friend says the receiver no longer can access the stick. dmesg is showing the stick :

So how can I access the data or reformat it to FAT ?

Thank you.

 

[mcobit]

Try gparted. It will show you info about the filesystem and lets you reformat it. There is a pnd on the repo.


If that doesn't work, you can try diskpart in windows. But be careful with that.


But its strange that the receiver isnt able to read it anymore.


What is the output of sudo lsusb ?

I've found testdisk to be great at restoring the FAT partition on the microSD card from my phone when it gets chewed up.

 

[joachim]

lsusb is showing the stick

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 003: ID 058f:1234 Alcor Micro Corp. Flash Drive
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

 I got the type : Auvisio PX 1143 - so far I have not found anything in Internet. diskpart doesn't show the stick.

 

[mcobit]

What about gparted?


There should also be a gparted live cd if you want to use a PC.

 

[joachim]

Gparted is not showing the stick :-(

 

[joachim]

after playing around a bit with dd and ls here is more info

dd if=/dev/zero of=/dev/sda

gives error


konnte /dev/sda nicht öffnen, kein medium gefunden (cannot open, no media)

with /dev/sdb:   writing 227 MB  + message no more memory

 df shows no /dev/sdb

ls-l /dev/sda
brw-rw---- 1 root plugdev 8, 0 Feb 17 17:50 /dev/sda

and ls-l /dev/sdb (after copy of a file with dd

-rw-r--r-- 1 root root 112901770 Feb 17 18:26 /dev/sdb
 

so it seems I got 2 disks (partitions ?) on the stick

but still no access in gparted

 

[rohezal]

sdb and sda are 2 different disks / devices. sda1 and sda2 are 2 partitions on the same device. I am sorry, but it looks like your stick is broken.

 

[joachim]

I tried testdisk but no success ( didn't find the stick)

Maybe it just died ?
