Greetings. I recently bought an IBM Ultrastar 18GB Model DDYS-T18350N which is an UltraSCSI 10000 RPM drive. Here are the system specifications: DELL Precision 420 - Pentium III at 800MHz - 256MB worth of RambusDIMMs - (2) on-board Adaptec aic7899 Ultra160 SCSI adapters - (1) 9.1GB - Fujitsu Model MAJ3091MP SCSI harddrive I simply wanted to add the IBM drive for more disk space. I am using linux-2.4.4-ac6. I made a single partition taking up the entire disk and issued the following: mke2fs -c -m1 /dev/sdb1 It starts out fine but then eventually it gets enough r/w errors and locks the machine up. Below is the log output. I can supply a kernel configuration file, but it probably is not necessary. I have been following some of the threads on the list concerning the aic7xxx driver, but may have missed some. I apologize if this is old information. It looks like a may have gotten a bad drive. Comments? Thanks. -Steve **************** LOG OUTPUT **************** May 9 21:08:57 ptecdev1 kernel: SCSI disk error : host 0 channel 0 id 6 lun 0 r eturn code = 8000002 May 9 21:08:57 ptecdev1 kernel: [valid=0] Info fld=0x0, Current sd08:11: sense key None May 9 21:08:57 ptecdev1 kernel: I/O error: dev 08:11, sector 725376 May 9 21:09:27 ptecdev1 kernel: scsi0:0:6:0: Attempting to queue an ABORT messa ge May 9 21:09:27 ptecdev1 kernel: (scsi0:A:6:0): Queuing a recovery SCB May 9 21:09:27 ptecdev1 kernel: scsi0:0:6:0: Device is disconnected, re-queuing SCB May 9 21:09:27 ptecdev1 kernel: Recovery code sleeping May 9 21:09:27 ptecdev1 kernel: (scsi0:A:6:0): Abort Tag Message Sent May 9 21:09:27 ptecdev1 kernel: (scsi0:A:6:0): SCB 7 - Abort Tag Completed.
