After connecting my usb pendrive there appears a new device /dev/sdf but I am not able to use it.
| Code: | # fdisk /dev/sdf
fdisk: cannot open /dev/sdf: No medium found |
dmesg

On windows the pendrive is visible but an i/o error occurs when opening. The pendrive is also visible inside Windows disk management but Windows cannot determinate the size of the pendrive.
I have also tried other usb slots. To me, it seems clear that the pendrive is broken. But want to make sure if there is something else I can possibly check. Thx. |

hercc,
| Code: | [ 7455.110245] sd 8:0:0:0: [sdf] Read Capacity(10) failed: Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK
[ 7455.110247] sd 8:0:0:0: [sdf] Sense Key : Hardware Error [current]
[ 7455.110248] sd 8:0:0:0: [sdf] Add. Sense: No additional sense information
[ 7455.110250] sd 8:0:0:0: [sdf] 0 512-byte logical blocks: (0 B/0 B) |
As Read Capacity(10) failed, the kernel does not know what size the drive is, then it all goes down hill.
You could try which will either read the partition table or add errors to dmesg.
Its possible it will do both too, with the partition table being rubbish.

@NeddySeagoon
| Code: | # fdisk -l /dev/sdf
fdisk: cannot open /dev/sdf: No medium found |
No additional messages on dmesg. |
