redhat es4 stopped recognizing external hard drive, gives errors mentioned when plugged in.
I have been using this external hard drive on redhat es4 for about 6 months now. I had formatted it for ext3 filey system, everything was working fine, but just recently it stopped working. I reformatted the ext hard drive with mkfs.ext3 command and device worked fine and its stopped again. I was however able to retrieve all the data using a third party software on a windows machine. Trying to figure out what I did, I remember unplugging it during a reboot after unmounting it though. When the machine went down, I unplugged it and plugged it back in after a while. I tried to enable some of the kernal modules but nothing is working. Appreciate your help.

Some of the error information would help...or did it just stop working?

dmesg:
usb 1-4: device not accepting address 8, error -71
usb 1-4: new high speed USB device using address 9
usb 1-4: device not accepting address 9, error -71
kernel version: 2.6.9-78
For some reason the device stopped communicating with the linux OS, because I was able to backu up the usb hard drive contents(which was not corrupted) in Windows using a third party software. After the error messages I got above, I could not even mount on /dev/sdb1, got errors saying /dev/sdb1 is not a block device.
I was just wondering what would be the best option of portable external hard drive for linux os. A lot of the products like IOmega, WD Passport mention they support Microsoft, is it just the embedded software they are talking about?I am looking for an external hard drive for linux to which I can copy tar files more than 4 G. Somebody on this site had recommended hard drive from seagate, is it as easy as plug n play? Can you give me some recommendations?
Other than umount /dev/sdb1, is there any other command I need to run before I unplug the device?
Thanks

I tried another cable as well, but it did not fix the problem. You are right I did an update to the system, from red hat network, applied some patches. Is that what you were referring to? After the updates,I started having all this problems.
Does it work on a live CD boot?
Sorry, what did you mean by this?
Also if you could suggest some alternative to my question above. - for making backups of large files, say > 4G from RHEL to a portable hard drive, which one would you suggest?
Thanks for your help.

Hi All,
back from hols, just to clear the last point up;
Live CD's are bootable cd distros, there are a load of them about, a couple based on RHEL are;
https://projects.centos.org/trac/livecd/
http://anorien.csc.warwick.ac.uk/mirrors/centos/5.2/isos/i386/CentOS-5.2-i386-LiveCD.iso
You could use tar to archive off and create a size limit and write a script to rename files, man tar for the options;
If you want to continue this Q post back and I'll post an example script.
