I formatted my pendrive with ext2 filesystem in ubuntu.Now its not detecting in ubuntu and windows.
Here's what the disk utility says.
Model: GENERIC USB Mass Stoarge Firmware Version: 1.00 Location: - Write Cache: - Capacity: No Media Detected Partitoning: - Serial Number: World Wide Name: - Device: /dev/sdb Rotation Rate: - Connection: USB at 480.0 MB/s SMART status: Not Supported Options... Format Drive -- Safe Removal Volumes: - Usage: - Device: Partition type: - Capacity: -
Then click on format drive and try to format with every option, its showing some error like:
Error creating partition table: helper exited with exit code 1: cannot open /dev/sdb: No medium found
Then I tried GParted to format USB drive, but it is not detecting. How can I repair these usb drive?
Result of following commands:
$ sudo cfdisk /dev/sdb FATAL ERROR: Cannot open disk drive Press any key to exit cfdisk $ sudo mkfs.ext2 /dev/sdb mke2fs 1.41.14 (22-Dec-2010) /dev/sdb is entire device, not just one partition! Proceed anyway? (y,n) y mkfs.ext2: No medium found while trying to determine filesystem size $ sudo mkfs.vfat /dev/sdb mkfs.vfat 3.0.9 (31 Jan 2010) /dev/sdb: No medium found
