X110 dropping off SATA bus

HI all,

 

I've got a SD6SB1M-064G-1022I with 2155 hours on it that's taken to dropping offline after being powered up for 3-4 days

 

The only thing which brings it back is power cycling which is "Not good" in a 24*7 server environment (It's half of a RAID1 set, so going down isn't catastrophic, but still not nice.)

 

OS is linux, not that it should make any difference in this setup.

 

SMARTCTL shows no errors 

5 Reallocated_Sector_Ct 0x0032 100 100 --- Old_age Always - 0
9 Power_On_Hours 0x0032 253 100 --- Old_age Always - 2155
12 Power_Cycle_Count 0x0032 100 100 --- Old_age Always - 22

169 Total_Bad_Block 0x0032 100 100 --- Old_age Always - 120

230 Perc_Write/Erase_Count 0x0032 100 100 --- Old_age Always - 2906
232 Perc_Avail_Resrvd_Space 0x0033 100 100 004 Pre-fail Always - 100
233 Total_NAND_Writes_GiB 0x0032 100 100 --- Old_age Always - 23184
241 Total_Writes_GiB 0x0030 253 253 --- Old_age Offline - 6424
242 Total_Reads_GiB 0x0030 253 253 --- Old_age Offline - 5110

 

It's reporting itself as hot (50C), but the drive case is only slightly warm to touch and it has a fan blowing directly over it so I'm not sure what's going on there.

 

FW is X230600

 

It was brought through a distributor. In this case I'm the OEM.

 

Any ideas why  it's dropping out and what I can do?

 

Thanks in advance.

Re: X110 dropping off SATA bus

Hello,

 

this drive you are using in a server is not qualified for this usage so i would suggest removing the drive from the server raid system and use a higher quality drive or even the specialized enterprise products that sandisk has released.

 

so in that case i suggest using the drive with a normal pc enviroment and not in a 24-7 one.

 

 

Good Luck

Re: X110 dropping off SATA bus

 

A drive which drops offline for no apparent reason isn't fit for purpose. This is a home system and not under high load and there are any number of reasons why I or anyonr else may choose to leave _my_ computer running 24*7

 

Your advice is reminiscent of the bad old days of the IBM Deathstars - a drive which damaged IBM's reputation so badly they exited the business - and it was only when Hitachi inherited the firmware that they discovered they had a 49-day bug in the firmware.

 

A computer is not a toy. Turning it off and back on again is never the correct solution, it's a last resort, despite what a certain toy company in Redmond may have conditioned people into believing.

 

If this is the Official Sandisk response then I'll forward it to tech media for commentary.
