any chance you can use the drive manufacturer's diagnostics to check the health of the drive? e.g. seatools, hgst drive fitness test or wd lifeguard
Thanks for your informative reply.
Actually what happened was that this drive developed this problem in February, a week or so after I bought it, I had to move the CPU chassis to replace a faulty monitor cable, since then this problem is occurring, it randomly comes and goes away, it has happened like this at least 10-15 times, I disconnect and reconnect the cable and it seems to go away but off late it is becoming un-resolvable. I've contacted Seagate and ran the tests they asked me to, and all tests came out as passed.
Looks like I have no other choice but to have it replaced?
Could it be possible dust could have gotten in SATA ports?
