My computer shows disk read error, i have tried to restart the pc for several times but still the same error, trying to reformat the pc still it can't read the cd. Any help please?

sounds like you might have a bad hard drive

it means your cd rom is defective try other cdrom... and format it again...or check your IDE cable or sata cable....

i have tried to change the data cable but still the same issue and i don't think the hard drive has an issue because i have been handling it with care.

My computer shows disk read error

just exactly when does it show this error

it shows the error at the start up and it doesn't continue after showing it.

"disk read error occurred press ctrl alt del to restart"

it shows the error at the start up and it doesn't continue after showing it.

"disk read error occurred press ctrl alt del to restart"

ok ,so it not reading you hard drive ,you need to get hands on help checking the harddrive,by removing it and trying a new/different harddrive in the computer

Or by placing that hard drive in another computer. Basically its still the same method suggested by caperjack. Lol. Most likely you need to clone the data to a new hard disk and use it.
