Hi there.

I'm having a situation that might just be me overthinking, but as this is my primary work computer, it's hard not to worry.

I use a late 2010 Intel iMac with a ST31000528ASQ harddrive (my understanding is that is a SeaGate model), and recently I started getting "disk error" messages in Photoshop while performing various tasks (opening, saving, cropping, resizing) as well as general system sluggishness. I ran Disk Utility and was given an error about "Invalid Note Structure," so I ran fsck in single-user mode and after that it no longer reported errors. My concern is that, afterwards, I ran a SmartReporter short Self-Test (several), all of which reported that the test has failed due to a "Read Failure." This also happened with a long test. I then looked at the SMART attribute list, which reads:

SMART Attributes Data Structure revision number: 10
Vendor Specific SMART Attributes with Thresholds:
ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE
1 Raw_Read_Error_Rate 0x000e 114 093 006 Old_age Always - 65030788

199 UDMA_CRC_Error_Count 0x003e 200 200 000 Old_age Always - 0


Do I have anything to worry about? Some of the numbers for error rates seem awfully high compared to postings I found elsewhere online, but I don't know much about this sort of thing.

Thanks so much for any help and advice, and please let me know if more information is necessary.

If this were my Mac and My drive I would replace it ASAP and RMA the drive back to Seagate for a replacement. Its failing based on the error counters.

The Reallocated_Sector_Ct and Reported_Uncorrectable attribute values are bad, but Raw_Read_Error_Rate, Seek_Error_Rate and Hardware_ECC_Recovered are OK. In fact the Seek_Error_Rate is actually 0.
