[QUOTE="countfufu, post: 1756288, member: 236999"] I scanned my HD with DriveDX and it revealed a "199 UDMA CRC Error Count". There's also an error message saying: "Total count of errors in data transfer via the interface cable. Each time the error is detected, controller requests a retransmission, thus slowing down the overall transfer speed. Increase of raw value could indicate problem with the power supply or data cable." Is there anything I should do? Here is the full system report. I've also attached the drive health indicator report: ### SYSTEM INFORMATION ### Application Name : DriveDx Application Version : 1.5.1.530 Application SubBuild : 0 Application Edition : Standalone Application Website : [url]https://binaryfruit.com/drivedx[/url] DriveDx Knowledge Base Revision : 6/6 Computer Model : MacBookPro8,1 OS Name : macOS OS Version : 10.10.5 OS Build : 14F2109 OS Kernel Version : Darwin 14.5.0 SAT SMART Driver Version : N/A ATA Command Support Tolerance : verypermissive N of drives with S.M.A.R.T support : 1 ### DRIVE 1 OF 1 ### Last Checked : May 1, 2017 4:58:42 PM EDT Last Checked (ISO 8601 format) : 2017-05-01T16:58:42 Advanced SMART Status : OK Overall Health Rating : AVERAGE 52.7% Overall Performance Rating : AVERAGE 52.7% Issues found : 1 Volumes : Macintosh HD Device Path : /dev/disk0 Total Capacity : 1.0 TB (1,000,204,886,016 Bytes) Model Family : HGST Travelstar 7K1000 Model : HGST HTS721010A9E630 Form Factor : 2.5 inches Firmware Version : JB0OA3J0 Drive Type : HDD 7200 rpm Power On Time : 9,648 hours (13 months 12 days 0 hours) Power Cycles Count : 643 Current Power Cycle Time : 0.7 hours === DEVICE CAPABILITIES === S.M.A.R.T. support enabled : yes DriveDx Active Diagnostic Config : Base config [hdd.default] Sector Logical Size : 512 Sector Physical Size : 4096 Physical Interconnect : SATA Removable : no Ejectable : no ATA Version : ATA8-ACS T13/1699-D revision 6 SATA Version : SATA 3.0, 6.0 Gb/s (current: 6.0 Gb/s) Bay # : 1 I/O Path : Attributes Data Structure Revision : 16 SMART Command Transport (SCT) flags : 0x3d SCT Status supported : yes SCT Feature Control supported : yes SCT Data Table supported : yes Error logging capabilities : 0x1 Self-tests supported : yes Offline Data Collection capabilities : 0x5b Offline Data Collection status : 0x0 Auto Offline Data Collection flags : 0x0 [Known device ]: yes [Drive State Flags ]: 0x40000100 [Last State Change Timestamp ]: 2017-05-01T16:21:43 [Last State Change Flags ]: 0x40000100 [Last State Change Diff Flags ]: 0x400 === CURRENT POWER CYCLE STATISTICS === Data Read : 3.3 GB Data Written : 1.8 GB Data Read/Write Ratio : 1.87 Average Throughput (Read) : 2.0 MB/s Average Throughput (Write) : 1.7 MB/s Operations (Read) : 133,275 Operations (Write) : 41,345 Operations Read/Write Ratio : 3 Throughput per operation (Read) : 26.3 KB/Op Throughput per operation (Write) : 45.4 KB/Op Latency Time (Read) : 0 ns Latency Time (Write) : 0 ns Retries (Read) : 0 Retries (Write) : 0 Errors (Read) : 0 Errors (Write) : 0 === PROBLEMS SUMMARY === Failed Indicators (life-span / pre-fail) : 0 (0 / 0) Failing Indicators (life-span / pre-fail) : 0 (0 / 0) Warnings (life-span / pre-fail) : 1 (1 / 0) Recently failed Self-tests (Short / Full) : 0 (0 / 0) I/O Errors Count : 0 (0 / 0) Time in Under temperature : 0 minutes Time in Over temperature : 0 minutes === IMPORTANT HEALTH INDICATORS === ID NAME RAW VALUE STATUS 5 Reallocated Sector Count 0 100% OK 197 Current Pending Sectors Count 0 100% OK 198 Offline Uncorrectable Sector Count 0 100% OK 199 UDMA CRC Error Count 768 100% Warning === TEMPERATURE INFORMATION (CELSIUS) === Current Temperature : 35 Power Cycle Min Temperature : 21 Power Cycle Max Temperature : 35 Lifetime Min Temperature : 15 Lifetime Max Temperature : 47 Recommended Min Temperature : 0 Recommended Max Temperature : 60 Temperature Min Limit : -40 Temperature Max Limit : 65 === DRIVE ERROR LOG === # | TIME OCCURRED | ERRORS | PRIOR COMMAND 5 9644 hours UNKNOWN ERROR READ FPDMA QUEUED 4 9633 hours UNKNOWN ERROR READ FPDMA QUEUED 3 9625 hours UNKNOWN ERROR READ FPDMA QUEUED 2 9625 hours UNKNOWN ERROR READ FPDMA QUEUED 1 9620 hours UNKNOWN ERROR READ FPDMA QUEUED === DRIVE SELF-TEST LOG === # | LIFETIME (H) | TEST TYPE | PROGRESS | STATUS | LBA of 1st error 1 9648 Short offline 100% Completed without error - 2 9359 Short offline 100% Completed without error - [ATTACH=full]26391[/ATTACH] [/QUOTE]
