Hi Mick, thanks for your reply on the topic. I executed the mkswap/dd combo a several times today. Since I have no logs I repeated again. Here are the results: solfire:/home/user>mkswap -L swap -f -c /dev/sda2 1 bad page mkswap: /dev/sda2: warning: wiping old swap signature. Setting up swapspace version 1, size = 6291448 KiB LABEL=swap, UUID=e742c0a6-862c-41e9-be4b-698b33c5a236 solfire:/home/user>dd if=/dev/zero of=/dev/sda2 bs=512 conv=notrunc dd: error writing ‘/dev/sda2’: Input/output error 1669369+0 records in 1669368+0 records out 854716416 bytes (855 MB) copied, 28.4799 s, 30.0 MB/s [1] 24047 exit 1 dd if=/dev/zero of=/dev/sda2 bs=512 conv=notrunc solfire:/home/user> I am a little anxious about the hdparm command... For me it is unclear what sector is meant: smartclt says: Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error # 1 Selective offline Completed: read failure 90% 14500 4288352511 From a previous posting I learned that "LBA" in this case is the byte counter. The sector is therefore 4288352511/512=8375688 However as a result of the dd command above I found this in the dmesg log: [48588.471905] end_request: I/O error, dev sda, sector 1773816 Now...what sector count fits what sector count ... ? I will not fire zeroes towards my hd this way before I know exactly to what I am shooting at... ;) Any light in all this shadow is heartly appreciated... Best regards, mcc
