Bad may include "has a faulty sector which the system is having trouble writing to" to "is too small for the image". In the case of the former, try adding "conv=noerror" to the dd command and bear in mind that that will produce an incomplete (but either useless or useful, depending on your intent) clone. > Can you please let me know how can I overcome this as the fdisk now returns as " > #fdisk /dev/sdc > "I do not know how to handle files with mode 81a4 > must set cylinders" So, either the error occurred while writing the partition table or the new disk is also failing to read data. > What can I do at know ? > In the meantime, if I want to format the target hard disk to have a > fresh disk , can you please let me know how to do that ? If you're going to be writing to the whole disk (/dev/sdc), then formatting is pointless: you'll only overwrite the work that the formatting did. Better to try smartctl/badblocks/etc to test the health of the new drive first. > > Thank you > > > -- > To UNSUBSCRIBE, email to debian-user-REQUEST@lists.debian.org > with a subject of "unsubscribe".
