<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> </head> <body bgcolor="#ffffff" text="#000000"> I just bought a Cavalry 1TB dual-3.5" external USB HD and attached it to a machine running Fedora Core 5 (which per some advice previously received here I intend to switch over to CentOS eventually). I partitioned and formatted it according to the directions provided by Red Hat <a href="http://www.redhat.com/docs/manuals/linux/RHL-7.3-Manual/ref-guide/s1-filesystem-ext3-create.html">here</a>. The drive mounts and I can put data on it. But these errors come up in dmesg on mounting/rebooting. Is this a bad drive, or am I messing something up? sd 2:0:0:0: SCSI error: return code = 0x08000002 sda: Current: sense key: Aborted Command Additional sense: No additional sense information end_request: I/O error, dev sda, sector 1953546336 Buffer I/O error on device sda, logical block 1953546336 sd 2:0:0:0: SCSI error: return code = 0x08000002 sda: Current: sense key: Aborted Command Additional sense: No additional sense information end_request: I/O error, dev sda, sector 1953546336 Buffer I/O error on device sda, logical block 1953546336 sd 2:0:0:0: SCSI error: return code = 0x08000002 sda: Current: sense key: Aborted Command Additional sense: No additional sense information end_request: I/O error, dev sda, sector 1953546336 Buffer I/O error on device sda, logical block 1953546336 sd 2:0:0:0: SCSI error: return code = 0x08000002 sda: Current: sense key: Aborted Command Additional sense: No additional sense information end_request: I/O error, dev sda, sector 1953546336 Buffer I/O error on device sda, logical block 1953546336 EXT3-fs error (device sda): ext3_check_descriptors: Block bitmap for group 880 not in group (block 0)!
