So.. I got a SMART fail count of 43696827 on a Samsung HD204UI drive in my NAS. That could/should be bad..
For the record, the complete SMART info on my ReadyNas is:
Model: SAMSUNG HD204UI Serial: SxHxJxKBxxxxxx Firmware: 1AQ10001 SMART Attribute Raw Read Error Rate 32 Throughput Performance 0 Spin Up Time 10147 Start Stop Count 687 Reallocated Sector Count 0 Seek Error Rate 0 Seek Time Performance 0 Power On Hours 45428 Spin Retry Count 0 Calibration Retry Count 0 Power Cycle Count 62 Program Fail Cnt Total 43696827 G-Sense Error Rate 28 Power-Off Retract Count 0 Temperature Celsius 28 Hardware ECC Recovered 0 Reallocated Event Count 0 Current Pending Sector 0 Offline Uncorrectable 0 UDMA CRC Error Count 0 Multi Zone Error Rate 4 Load Retry Count 0 Load Cycle Count 687 ATA Error Count 0
Raw Read Error Rate non-zero, just over five years of use. Time to replace or what?
Just a fun fact, I have an identical drive in the same NAS, with the same (difference less than 100) number for this SMART Parameter B5, with a raw read error rate of 0.
Time to pay attention to this firmware update: http://knowledge.seagate.com/articles/en_US/FAQ/223571en? Nope, my drives were manufactured after december 2010, and after that date, no new firmware was released for these drives.
I’ll just live with it, backup (more) often and perhaps, I’ll replace a disk (or two)..
