Jessie not booting with unable to mount rootfs on unknown block (179,2)

Wed Jan 03, 2018 8:02 pm

Ive got a persistent problem with Raspian Jessie not booting with "unable to mount rootfs on unknown block (179,2)"

Ive written the Raspian img file to the SD card using dd, its a brand new 16GB Kingston so I dont think the card itself is faulty.

Ive rewritten it several times and tried re-downloading the img in case the original was corrupted.

The cmdline.txt file contains root=PARTUUID=37665771-02 and the output from fdisk is as follows:

Code: Select all

Disk /dev/sdb: 15.2 GiB, 16358834176 bytes, 31950848 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x37665771

Device     Boot Start     End Sectors  Size Id Type
/dev/sdb1        8192   93236   85045 41.5M  c W95 FAT32 (LBA)
/dev/sdb2  *    94208 3629055 3534848  1.7G 83 Linux

which seems to be OK. Interesting I cannot mount sdb2 on my linux desktop it gives a bad superblock error but I cant understand what the issue is.

Can anyone help enlighten me please?
