Dell SAS Raid Storage Manager Error?

Poweredge sc 1430, SAS 5 IR adapter 0010.49.00 firmware, Mirrored Sata wdc-wd2500YS drives, Dell SAS Raid Manager v 2.08, latest drivers on sas 5 ir, storport.sys 5.2.3790.3959,
SBS 2003 latest updates

Started getting  this error in event log and the same in Raid storage manager:
Event Type:      Warning
Event Source:      MR_MONITOR

Error was only happening during the off hours mostly with the backup to an external USB drive.
now it seems to be happening during the day. No errors in system events, the above error in application events.
System performance slows during this but CPU usage is minimal. 4 gig ram on server and using Exchange 2003.
System memory use is also minimal.
If I reboot all is fine again, but will get one or two MR_MONITOR errors as above.

I searched net but cannot find any solutions.

I did have one warning that controller fixed medium error I believe Event ID 47, but that was all.

I did not get to update the optional firmware update for 5ir controller.
Hard drives with two partitions and both are 75% free.
Everything has run fine for a few years.

This error is not listed in the Dell raid storage manager manual, but medium corrected is listed. No other info.

The Raid manager does indicate any other problems but this.

I am stumped, please help.

Thanks and sorry for this long post.

Many manufacturers use LSi products. Intel is one.

Here is the document that interprets all of those codes:

You are getting Sense Key 3 Errors, this is an indication of bad blocks at either the logical or physical layer.

You should look at replacing drive 0 as soon as possible once you have a full backup
3/11 sense information means that you have an unrecoverable READ error.  Your USB-attached disk has officially lost some data.   If you do a chkdsk and click off the options to do a full media scan then at least it will force a read and tell you (if you are lucky) what you have lost.

But at this point, all backups are suspect, and if this is your only backup device, then I suggest purchasing another one, and immediately performing a full backup

Although there may be something going on with the USB

This message is being generated by the Raid Controller and reporting it on Physical Disk 0 attached to the raid controller
3       11       00       Medium Error - unrecovered read error. Its better to replace hard drive PD 0:0.
Check the controller logs. there might be more media errors.
One clarification ... if this is a one off, i.e, you only have a few, and haven't seen a dozen of them just crop up out of nowhere on this one disk, then no need to replace the drive.  Just keep an eye on it, and RUN data consistency checks often.

Drives have thousands of spare sectors.  A single NRE error is a statistical certainty, not some obscure thing that isn't ever supposed to happen. You can get this from an improper shutdown while the disk is writing, as a matter of fact.
Your much better off being proactive about this issue than assuming that it is a minor block reallocation issue. Run the Dell Online Diagnostics or the offline 32-Bit diagnostics to verify and keep yourself out of a potential data loss situation
