Last Velociraptor analysis before moving to HW-RAID card.

With a small loop, I read every sector on the disk and captured the dmesg.

for dir in $(seq 1 100)
do
  mkdir -p "$dir"
  # total sectors = 586072368
  # but it errors if you try and read the last one, so 586072368-1
  sector=1
  sector_max=586072367
  while [ $sector != $sector_max ]
  do
    hdparm --read-sector $sector /dev/sda > $dir/$sector.sector 2>&1
    dmesg >> $dir/$sector.sector 2>&1
    printf "sector $sector/$sector_max\r"
    sector=$(($sector+1))
  done
done

After reading the entire disk, one sector at time; (1319, etc, is a regular sector):
-rw-r--r-- 1 root root   1319 2008-11-22 17:14 2.sector
-rw-r--r-- 1 root root   1319 2008-11-22 17:14 3.sector

A bad one (out of quite a few)
-rw-r--r-- 1 root root    820 2008-11-23 01:04 4765653.sector

Suffice to say-- time to try a HW RAID controller, will be getting a 3ware
9650SE-16 port card in a few days and I will see how the drives work with it, if they continue to have problems I will replace them all with 1TiB disks and be done with it as this is consuming too much time.

Example of one bad sector: (but read below to see what is REALLY strange)
# cat 4765653.sector
/dev/sda:

After this ran, I re-ran a short+long test:
SMART Self-test log structure revision number 1
Num  Test_Description    Status                  Remaining  LifeTime(hours)  LBA_of_first_error

# 2  Short offline       Completed without error       00%       870         -

..... No errors!

In any case, will provide an update once I move over to the 9650SE and we'll
see how that goes, thanks all for those who responded in regards to my previous
velociraptor-issues :)

=== START OF READ SMART DATA SECTION ===
SMART Error Log Version: 1
ATA Error Count: 265 (device log contains only the most recent five errors)
	CR = Command Register [HEX]
	FR = Features Register [HEX]
	SC = Sector Count Register [HEX]
	SN = Sector Number Register [HEX]
	CL = Cylinder Low Register [HEX]
	CH = Cylinder High Register [HEX]
	DH = Device/Head Register [HEX]
	DC = Device Command Register [HEX]
	ER = Error register [HEX]
	ST = Status register [HEX]
Powered_Up_Time is measured from power on, and printed as
DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes,
SS=sec, and sss=millisec. It "wraps" after 49.710 days.

Error 265 occurred at disk power-on lifetime: 866 hours (36 days + 2 hours)
  When the command that caused the error occurred, the device was doing SMART Offline or Self-test.

  After command completion occurred, registers were:
  ER ST SC SN CL CH DH
