Is this your PCB? https://s.turbifycdn.com/aah/yhst-14437584971410/hde721010sla330-0a29896-0a58730-0a90156-0a38876-ba3013-oa90156-oa58730-oa29896-3-5-sata-hitachi-circuit-board-fw-17.gif There appears to be a linear 3.3V (?) regulator (Q2 near SATA power). I suspect that it powers the SDRAM and ROM....

Here are photos of the 800069 equalizer PCB: https://photos.app.goo.gl/f4hYtXuKbf8vdeTr9 They suggest that U3 and U5 are SN74LVC2G240 buffers. SN74LVC2G240, Texas Instruments, 2-ch inverters with 3-state outputs, 1.65V - 5.5V, marking C04J, VSSOP-8: https://www.ti.com/lit/gpn/sn74lvc2g240 U12 appear...

Perform a Tx-Rx loopback test. Meaning what? Connect the Tx output pin to the Rx input pin, then type something on your keyboard. You should see the typed characters being echoed on the screen. Alternatively, create a test file consisting of 1 million repetitions of 0x55 or 0xAA (alternating 1s and...

Perform a Tx-Rx loopback test.

SSD health is most often reported by the SSD via a specific health attribute. It is usually calculated on the basis of the average number of P/E cycles, or percentage of rated TBW, or both. These numbers don't reflect the error rates that are reported in other attributes. All SMART tools will get th...

When it comes to mOLD and btec sectors on SMR Seagates, that actually may save a client's data from Spinrite, assuming that every read is with a long timeout. If under 500ms, those sectors will report as bad, rather than give garbage data. I can confirm that a Rosewood ST2000LM015-2E81 produced &qu...

This is my guess as to the test point (X) for the Reset* pin on a 2060-810003 PCB. The bridge is an Asmedia ASM225CM.

This is my guess as to the test point (X) for the Reset* pin on a 2060-800067 PCB. A point-to-point continuity test with a multimeter should confirm or reject my hypothesis.
