Hi,

I have an hard drive that connects to my laptop through the USB 2.0 interface.it was bought at 2006. some months before, it started to report error onread. I reformatted it use the

mkfs.ext3 -c /dev/sda1

But it didn't detected any badblock.
then I copied some files to it, then read out, it shown the error:

usb 5-4.3: reset high speed USB device using ehci_hcd and address 5
sd 0:0:0:0: [sda] Result: hostbyte=0x07 driverbyte=0x00
end_request: I/O error, dev sda, sector 214814735
usb 5-4.3: reset high speed USB device using ehci_hcd and address 5

I think that's because there are some badblocks on the disk, so I ran

fsck.ext3 -c /dev/sda1

but this time it still didn't find out any badblock.

any idea about it? thanks.

The error could also be due to faulty hardware.

Thanks. maybe you are right. when I tried to use different usb to ide adapter to connect the hard drive, things became different. but there still has some errors when reading or writing.

Note that modern hard drives remap bad sectors when they can. Your
reformatting might be reassigning a bunch of bad blocks, then it's
finding more when it tries to read the next time....

Oh dear, that's quite a bad news.
that's what I have encountered. when I heard the noise of hard drive reset,and checked the dmesg to make sure about it, I reformatted the hard drive,then copy my data in again, it worked. but after some days, it starts to tell me about read error again.
so, this means the hard drive has died, right?

Install smartmontools and interrogate the smart data on the drive, if
it reports a reallocated sector count and it keeps growing you know
your drive is on it's way out. A static reallocated sector count
doesn't necessarily mean your drive is bad but if that count keeps
growing it's not a good sign.

Note that I don't believe smartmontools will work thru the USB
interface - you'll have to use the native SATA or ATA interface (e.g.
install it in a tower)

Assuming an ext2/3 fs, try e2fsck -c -c (the second c does a
non-destructive read-write test of the filesystem).
