The "failure rate" is perfectly normal. I've been watching Seagate's forums over the past few years, and such "reallocated sector" issues are very common. It's particularly prevalent in refurbished drives, so I suggest that the OP stay away from these. Unfortunately a warranty replacement will probably be refurbished. AISI, refurbishing a drive with bad sectors or a bad head is like sweeping dust under the carpet. The exception is when a head is "cut', but this reduces the capacity of the drive.
I would add that data recovery companies generally see dead drives rather than "weak" ones, so their observations regarding reallocated sector counts would not necessarily match typical user experiences.
Myth at the borders of BS zone. But this is a serious forum hence some pills of real facts :
0) How did you know that all the drives with "bad block" issues were "particularly prevalent" refurbished ?
Refurbished by SEAGATE and clearly stated on label ? There was a time when , here, you would ONLY find seagate factory refurbished drives so there was no alternative. I have bought hundreds of them and they run monitored 24/7 , some since the end of 2006-2007.
ZERO problems. One thing is sure : in MY environments or where I have the control, NO tinkering , patching, updating or tampering of any manner is allowed, less than less firmware tinkering.
1) All the RMAed drives are inspected and reworked and return into market if PROVEN to be within specs. They don't say it anymore on label or they do or don't do it at their pleasure. It can be discovered, anyway....
Heads are deactivated only when necessary as it will decrease also the value of the drive.
Everything that happen has a convenience for the companies otherwise it wouldn't happen.
2) Get some BRAND NEW out of the box drives , every brand, and ask a professional with the real professional tools
you don't have (otherwise you would already know certain things) to show you how many servo defects and surface defects (and possibly the kind of them) were detected and healed at factory (they are still there but simply the drive knows where "not to go"). On a 500 GB drive the count can reach even 1000, 1500 and the locked out TRACKS (entire track!) to avoid at every cost can perfectly be 20, 30...
There's enough space for 10 or even 100, 500, 1000 more blocks, in this case they are not even hard errors as you GUESS. They are something else but I won't tell you, sorry.
3) We see weak drives. And with some magic , DATA ! Even without opening the drive. Exactly where all the internet free stuff hang or crash. Knowing what to do does wonders, not knowing it and playing does disasters.
Final note : I am curious to know if you or someone you like (or someone who likes you, who knows?) would offer pro refurb service, would you be advertising and suggesting his website at every given post where there is a problem of bad blocks. Would in this case not be "sweeping dust under the carpet" but "a professional service that saves money and also is good for environment" or what else ?
This only because your behaviour - at least to me - is strange : since when you came in 2009 every now and then you had something to say (and not kind words) against the DR community, suddenly NOW you are suggesting or better advertising... DR SERVICES. No more DIY ? No more suggestions about buying a tool then try to resell it later when the job is done ? Would you mind explain what or who did you change your mind "180 degrees" ?
P.S. Your last ban (the 3rd on this forum) was because of the n-th insult and attack to THIS DR community, not for any other reason.
