eMMC card Broken or Damaged?

[ Edited ]

Hello, 

 I have ultra Sandisk Memory Card 8 GB .When I am trying to format it under linux -Ubuntu using DIsk Utility I am getting the  error.

=> Are you sure you want to format the drive?

This operation concerns the drive "7.9 GB SecureeDigital/SecureDigital Drive"(SL08G)

 

=> Error formattig drive

An error occurred while performing an operation on "7.9 GB SecureeDigital/SecureDigital Drive" (SL08G):The operation failed.

 

Detals : 

Error Creating partition Table:helper exited with exit code 1:Error calling fsync(2) ob /dev/mmcblk0:input/output error

  

 I am not sure If I have damged it or what?

Also when I try to run the below command : 

 

export DISK=/dev/mmcblk0

 

sudo dd if=/dev/zero of=${DISK} bs=1M count=20

 

I get this error : 

 

 

Checking that no-one is using this disk right now ...

BLKRRPART: Input/output error

OK

 

Disk /dev/mmcblk0: 121008 cylinders, 4 heads, 16 sectors/track

sfdisk: read error on /dev/mmcblk0 - cannot read sector 0

 /dev/mmcblk0: unrecognized partition table type Old situation:

New situation:

sfdisk: read error on /dev/mmcblk0 - cannot read sector 0 Re-reading the partition table ...

BLKRRPART: Input/output error

 

If you created or changed a DOS partition, /dev/foo7, say, then use dd(1) to zero the first 512 bytes:  dd if=/dev/zero of=/dev/foo7 bs=512 count=1 (See fdisk(8).)

 

 

lsblk gives this : 

 

lsblk shows :

NAME    MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda       8:0    0 298.1G  0 disk

sr0      11:0    1  1024M  0 rom  
mmcblk0 179:0    0   7.4G  0 di

Re: eMMC card Broken or Damaged?

if formatting failed the card is probably bad. If it is under warranty contact sandisk support for replacement.

Re: eMMC card Broken or Damaged?

OK finally i got this thing resolved,What a stupid I was.I was using the san disk emmc with the Kingston MMC adpapter.Was not knowing that they are in-compatible across all the emmc.
