Can not recover lost partition, Input/output error

#1 Post by carlosrp » 02 Jan 2014, 12:19

Hi,

I am trying to recover a partition on a Linux system. The disk should have 2 partitions and I can even access the second one from command another file system. I run testdisk, run both searches but can not see neither partition. All I get is Input/output error. Here are the first lines of the log file:

Partition table type default to Intel
Disk /dev/sdc - 1500 GB / 1397 GiB - ATA ST31500341AS
Partition table type: Intel

Analyse Disk /dev/sdc - 1500 GB / 1397 GiB - CHS 182401 255 63
Current partition structure:

Partition: Read error

search_part()
Disk /dev/sdc - 1500 GB / 1397 GiB - CHS 182401 255 63
file_pread(6,16,buffer,32(0/0/33)) read err: Input/output error
file_pread(6,3,buffer,48(0/0/49)) read err: Input/output error
file_pread(6,3,buffer,95(0/1/33)) read err: Input/output error
file_pread(6,8,buffer,111(0/1/49)) read err: Input/output error
file_pread(6,11,buffer,158(0/2/33)) read err: Input/output error
file_pread(6,2,buffer,2080(0/33/2)) read err: Input/output error
...


Could somebody please help me on what else can I do?

Thanks,

Carlos

If you only get error messages, you need to contact a data recovery company.
If it's only a bad sectors area, you can try to clone the disk yourself using ddrescue as described in https://www.cgsecurity.org/testdisk.pdf
