For copying the directory you have to give cp -R. For details you can look at man cp.

sandip thanks, but the copy is a simple copy file text to another, is not a directory copy.

someone knows what is the solution to hies error.

thanks.

Hi,

Looks like you have a disk problem or you are in need of a scsi/jfs patch.

Hope this helps.

Hi,

Check the disk where the file is located

dd if=/dev/rdsk/c1t2d0 of=/dev/null bs=1024k

if inputs=otputs then your disk is OK. Or else your disk may have bad sectors.

or else restore the file you are copying from backup and try again.

Hi Javier

This looks like a disk problem , caon you try copying to some other place if not a big file , it may also be some block in a partioin bad , that will eventually lead you to cahnge the disk . though you can identofy the problem .

dd if=/dev/rdsk/cxtydz

diskinfo /dev/dsk/cxtydz

should give you more information.

This is definitely a hardware error. You need to take steps to save any new data as soon as possible and verify that your backup procedure will actually produce a useable tape. I've never seen a disk error get better, only worse.
