Hi all folks, I issue following command to check hard drive # hdparm -Tt /dev/hda /dev/hda: read( ) failed: Input/output error Timing buffered disk reads: read() failed: Input/output error Kindly advise how to rectify this error Thanks in advance. B.Regards Satimis

I was just recently working with the hdparm command. First at all you should be in single user mode. If you still get that error in single user mode, then you probably have a deffective hard drive. I will suggest to back up your data (in another disk or CD) because that harddrive might crash at any time. To run in single user mode, open a terminal and as root type: telinit 1 that will take you to single user mode. Once you are done, type telinit 5 to go to run level 5, which is X graphic environment.

Hi, Thanks for your advice. Now I have all important data burnt on CDs. # init 1 sh-2.05a# hdparm -tT /dev/hda ..... ..... end-request: I/O error, dev 03:00(hda),sector 2008 hda:tray open same I/O error in sectors: 2012, 2016, 2020, 2024, 2028, 2032, 2036, 2040, 2044, 0, etc 4 read ( ) failed: Input/Output error Maybe there are some other errors on top-screen. I don't know how to move up. PageUp and arrow don't work This is a ATA66 7,200 rpm 10G hard disc connected to a PCI ATA66 controller card. It has been used for some times. No error has been found during daily operation. Kindly advise how to fix this I/O error. Thanks in advance. B.Regards satimis
