Hi. I bought an external USB hard drive last week and reformatted it as ext3. I can mount it and read/write files, but for some reason it periodically disconnects and reconnects. I would like to use it as permanent storage, hooked up to my computer all the time. I added a label to it and put a line in fstab to mount it. But I'm getting lines like these in my /var/log/messages: Feb 5 00:07:05 pigpen kernel: usb 1-7: USB disconnect, address 4 Feb 5 00:07:06 pigpen kernel: scsi 2:0:0:0: rejecting I/O to dead device Feb 5 00:07:06 pigpen kernel: EXT3-fs error (device sdd1): ext3_find_entry: reading directory #2 offset 0 Feb 5 00:07:06 pigpen kernel: scsi 2:0:0:0: rejecting I/O to dead device (and more...) It's then quickly found again, though assigned sde1 in this case and of course not automatically mounted. I'm assuming the filesystem also requires an e2fsck because it was disconnected. Does anyone know what might be causing this? Is it likely a hardware issue? I have another external drive that I've been using without problems for about a year, but it's firewire. Previously, I was using both drives with autofs, but the new drive had some problems with that approach, too. (Now that I've learned about filesystem labels, that seems like the way to go anyway.) I'm running F8 with all updates (kernel-2.6.23.14-107.fc8). Thanks, reid
