From: Glenn English on 15 Apr 2010 22:20 SMART is warning a lot about a couple week old OCZ SSD. This is my first SSD, and I don't know if this is normal or I have a defective drive. Looks broken to me, but... It's connected to an Asus AT3CG-I mobo. Some output from webmin -- smart's writing in the logs quite a bit, too, about uncorrectable errors and such: smartctl version 5.38 [x86_64-unknown-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF INFORMATION SECTION === Device Model: OCZ-VERTEX Serial Number: 26G39UFKZSO46VR1E334 Firmware Version: 1.5 User Capacity: 32,017,047,552 bytes Device is: Not in smartctl database [for details use: -P showall] ATA Version is: 8 ATA Standard is: Exact ATA specification draft version not indicated Local Time is: Thu Apr 15 20:02:18 2010 MDT SMART support is: Available - device has SMART capability.

Smartctl doesn't know what those are, but it somehow knows they are failing? With a raw error count of zero, no less? You don't have a bad SSD Glenn. Apparently the S.M.A.R.T data structures/attributes for SSD have yet to be standardized as they have been for mechanical disks. Many of the mechanical disk S.M.A.R.T attributes don't exist for SSD and vice versa. Newer versions of the Linux smart tools may fix this problem, or you could hack up some file tables yourself to get your tools to understand that OCZ SSD's S.M.A.R.T attributes. Your SSD is fine. I think the Linux S.M.A.R.T tools aren't up to speed yet WRT SSDs. -- Stan -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble?

I think it is a little bit unusual for the drive to have a threshold of zero for 195-197. And it makes me suspicious that not even attributes 9 and 12 are counted properly. > 204 Shock_Count_Write_Opern 0x0000 000 000 000 Old_age Offline FAILING_NOW 0 > 206 Flying_Height 0x0000 001 000 000 Old_age Offline In_the_past 0 I think both of these values don't matter to SSDs at all. They shouldn't care about shocks and don't have a head which could "fly high". Conclusion: While the warnings indicate a broken disk, they look a bit fishy to me. It looks the manufacturer used standard firmware from a regular hard drive and didn't adapt it to SSDs properly. For comparison, here are *all* values my Intel X25m reports via SMART: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 3 Spin_Up_Time 0x0000 100 000 000 Old_age Offline - 0 4 Start_Stop_Count 0x0000 100 000 000 Old_age Offline - 0 5 Reallocated_Sector_Ct 0x0002 100 100 000 Old_age Always - 0 9 Power_On_Hours 0x0002 100 100 000 Old_age Always - 1703 12 Power_Cycle_Count 0x0002 100 100 000 Old_age Always - 509 192 Power-Off_Retract_Count 0x0002 100 100 000 Old_age Always - 445 232 Available_Reservd_Space 0x0003 100 100 010 Pre-fail Always - 0 233 Media_Wearout_Indicator 0x0002 097 097 000 Old_age Always - 0 225 Load_Cycle_Count 0x0000 200 200 000 Old_age Offline - 45681 226 Load-in_Time 0x0002 255 000 000 Old_age Always - 0 227 Torq-amp_Count 0x0002 000 000 000 Old_age Always - 0 228 Power-off_Retract_Count 0x0002 000 000 000 Old_age Always - 0 I think I would try finding and using the manufacturer's diagnostic tool (which might be a pain without Windows) and see what it reports. I would expect it to report no problems. J. -- I am no longer prepared to give you the benefit of the doubt. [Agree] [Disagree] <http://www.slowlydownward.com/NODATA/data_enter2.html>

Fast, too... That's a perfect application for a small SSD. You probably could have even got by with an 8 Gig'er and saved some cash. -- Stan -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble?
