sudo fsck /dev/sdcx

x being your partition number, and sdc your device (could be sdb, sdd, sde...).

This simple operation will remove bad file sectors on either a partition or the entire device.

When you want to nuke your device, and create a new data partition :

For ext4 :
sudo mkfs.ext4 -f /dev/sdc1 (sd... vary depending on your installation)

For Fat32:
sudo mkfs.msdos -f 32 /dev/sdc1 (same caveat for sd... )

Hopefully, your flash drive will work again.

Some years ago I was compelled to flash the original firmware from windows to a broken usb stick.

You already have a thread. Why another one?
how to repair a corrupted USB flash drive

Why "Subject description: for Mintpup or Xenialdog"?

bigpup alread told you

I use Windows 7 for repairing my USBs. insert the defectuous one. Windows will ask you i you want to check it and repair. Efficient.

No more of a problem than doing it in Linux.
It will NOT report an error unless there IS one so stop being melodramatic.

I did not realise that windows now repairs ext1. ext2, ext3, ext4 file systems on a corrupted USB drive.

When did that start?

In which case it is definitely going to be safer doing it in Windows since the Linux FAT32 support is based on ripped off code.

Notwithstanding anyone's personal preferences, the following can be surmised from this thread.

EXT1, EXT2, EXT3, EXT4, NTFS, FAT32 can be repaired by Linux.

NTFS and FAT32 can be repaired by Windows.

It is NOT safe repairing FAT32 and NTFS using Linux.
It can be done, but is not the safest way.
If you want an argument, all the EXTn extenion formatted drives can be repaired under Windows.

When are you people going to realise that Linux is NOT the be and end alll of OSs. Others do exist and many are better than Linux at doing specific things.
It is a case of horses for courses; use the better tool for the specific job, especially if there are problems.

Good thing I never read this thread when repairing my sd card fat 32 puppeee frugal installs on my eeepc 701SD

http://murga-linux.com/puppy/viewtopic.php?p=773859#773859

Back when it would not boot because of improper unmount due to power failure <drained battery> or a brain fart and ejecting sd card too early.

I'd boot A live gparted session on a Puppy live usb just made for this repair . Run a check on unmounted puppeee sd card. Finish. Reboot.
Pull Puppy pendrive with gparted on it. Leave Puppeee sd card in. Done. Fixed.
Problem solved, Problem never mentioned.

Like I said. Good thing I did not find this thread earlier. Shocked

I also have Puppy Rescue. for pendrives completely garbled, to trash definitively. To save some files, generally my pictures.
