Non-fatal error on SCSI drives

Hello!

I am having some problems with DBAN 1.04 and SCSI drives. I have to erase 12 drives and DBAN seems as the perfect solution. However, I get a non-fatal error and the program exits.

I have tried 2 different drives and two different controllers with the same problem. My log files:

Some parts of the dmesg.txt:

I get the I/O error in the end of dmesg with the same sector every time. I have tried the DoD and quick erase with the same bad result.

Help!

Probably nothing wrong with the disk...

Well, as I wrote, I have tried with two different disks of the same type and they both fail at the same sector according to dmesg.txt.

I tried using a commercial eraser (Expert Eraser from IBAS) and it worked perfect with a DoD wipe on the disk where DBAN failed. So it seems like there is noting wrong with the disk(s)...

However, the disks might be a bit special. They come from a Sun A1000 storage and are SUN rebranded... Is there any tuning I can do with DBAN to get it to wipe these disks? Do you need more logs? (The disk model is embedded in the dmesg.txt in my previous post...)

I would really be happy if you could help me, I have 11 more disks like this one that needs wiping...

Regards,
/Johan

This is not an issue. I have several Sun branded disks that are compatible.

Really? Did you check whether it left data at the end of the disk?

The log reports that the wipe fails at sector 35378532, which would be near the end of this disk.

If DBAN fails on all Fujitsu MAJ3182M disks at sector 35378532, then the drive firmware is likely reporting an incorrect number of sectors. This is a common problem with 9 gigabyte SCSI disks, but this would be the first report of the problem with an 18 gigabyte disk.

Check whether Fujitsu is providing a firmware upgrade for the MAJ3182M.

If DBAN fails on these Fujitsu MAJ3182M disks at different sectors, then the media is likely bad. The vendor's diagnostic program might provide more insight.
