Unraid-arr Posted December 13, 2019 Share Posted December 13, 2019 Hi Guys, I have this one HDD that shows particularly high "UDMA CRC error count" - 106411915 and still passes SMART Extended Test. CA Fix Common Problems Plugin also showed notification once when I plugged the drive first time into the server saying "High UDMA CRC error count". Should I keep the drive for a rainy day or should I chuck it into the Trash Can without doubt? I swapped it for SSD in my old laptop thus the 8979 Power on hours. Currently the drive is an Unassigned empty spare just in case I need it.

JorgeB Posted December 13, 2019 Share Posted December 13, 2019 UDMA_CRC errors are a connection problem, not a disk problem, usually a bad SATA cable, but note that attribute doesn't reset, so only if it keeps increasing there's a problem. Quote Link to comment

Hey johnnie.black, Thanks for chiming in. I actually saw this same reason mentioned online when I was researching this. I have re-seated the Drive a few times and it keeps on increasing with every smart test / preclear I do on the disk. It is on my rear 2.5" Drive Slot of R720xd so I feel that is good as well. Examples below. Maybe you can get some more clarity with this. preclear_report_XXXXXXXXX_2019.09.28_06.39.23.txt ############################################################################################################################ # # # unRAID Server Preclear of disk XXXXXXXXX # # Cycle 1 of 1, partition start on sector 64. # # # # # # Step 1 of 5 - Post-Read verification: [3:07:27 @ 88 MB/s] SUCCESS # # Step 2 of 5 - Verifying unRAID's Preclear signature: SUCCESS # # Step 3 of 5 - Writing unRAID's Preclear signature: SUCCESS # # Step 4 of 5 - Zeroing the disk: [3:07:42 @ 88 MB/s] SUCCESS # # Step 5 of 5 - Pre-read verification: [3:06:47 @ 89 MB/s] SUCCESS # # # # # # # # # # # # # # # ############################################################################################################################ # Cycle elapsed time: 9:22:07 | Total elapsed time: 9:22:08 # ############################################################################################################################ ############################################################################################################################ # # # S.M.A.R.T.

Hi Johnnie.black, As promised, here is the report from today. Error count has gone up 2469362 again. This was a completely different computer, drive connected via SATA port on MOBO with fresh Unraid boot drive. I am a little happy that it is not a "cable, back-plane or controller problem" on my server. That would have been expensive lol.

JorgeB Posted December 15, 2019 Share Posted December 15, 2019 If the error continues to increase in another server it's likely the disk, but it's extremely rare, in fact I don't remember ever seeing it ever before, but of course it's not impossible. Quote Link to comment

Thanks johnnie.black. I am tilting towards drive issue myself and would keep a close eye on the drive. Will update here when drive dies. For a 1Tb Toshiba Laptop drive, It has seen 31.75Tb Total lbas written and 29.5Tb Total lbas read so I am not sad to let it go. Thanks for helping. Cheers! Quote Link to comment
TheWoodser Posted August 28, 2020 Share Posted August 28, 2020 Is this a "power" problem or a "SATA" problem? Thanks for the help. Quote Link to comment
