Although fix disk has done lots to help I have lost faith in the disk and will be replacing it as soon as the new one arrives.

Thanks for all the help and interest

PS Fixdisk appears to have sorted out the LBA0 problem
 
I ran yet another fix disk yesterday (five hours worth) and the disk seems to have 'settled' down.
I am not sure why you think it has settled down; it is still busily reallocating sectors and the count has doubled since your first posts. I fully endorse your decision to replace the hard drive; the sooner the better.
 
Because LBA0 is where the partition table is stored and if that is unreadable fixdisk doesn't know how the file systems are arranged. I agree it is a bit odd that it gives a lot of trouble because I wouldn't expect it to be written to very often.
...
fixdisk knows what sort of partition schemes it should find and constructs a new partition table in LBA0 if the original is corrupted and it finds a matching arrangement of filesystems.
...Do we need some way to mark [LBA0] bad so the controller remaps it? ...
fixdisk with the long SMART test option should detect a bad sector 0 and subsequently call (conceptually) hdparm --read-sector || hdparm --repair-sector which should force the sector to be remapped if it is still bad. Problems may occur if the sector is marginal so that the re-read succeeds and the remap is skipped (the sector is removed from the controller's pending list), or, I suppose, if the remapped spare sector is also bad.

It should be possible to force the remap of a marginal sector 0 with some sequence of commands in maintenance mode like these:
Code:
# set these parameters as appropriate
hdd=/dev/sda
physicalss=4096
logicalss=512

dd if="$hdd" of=/tmp/sector0.bak count=1 bs="$physicalss" conv=noerror &&
  for i in `seq 0 $((physicalss / logicalss - 1))`; do 
      hdparm --repair-sector "$i" --yes-i-know-what-i-am-doing "$hdd"; 
  done &&
dd if=/tmp/sector0.bak of="$hdd" count=1 bs="$physicalss"
 
Thanks hairy_mutley - had a look and, although the disk is recognised, it directs me to Support. I may follow this up later today.
 
That is an awful lot of errors isn't it? Not something I'd expect from a drive that young unless it had been stored badly/exposed to extreme temperatures or similar. That many bad blocks and sector remaps suggests hardware faults with the drive itself - last time I saw something like that it was an old 30GB Maxtor drive years ago where the airtight seal had been pierced and was letting dust into the platters, which I only noticed when I took it out of the PC tower. When I sent fix-disk over mine last week it only found (and repaired) file system errors.

Definitely would follow it up with Seagate and see if they will replace free of charge. The original SSD failed in my HTPC (kept wiping everything; this is why you always keep backups especially of the OS drives) and when I told Kingston and provided serial number etc they traced it to a faulty batch. Their solution? Send me out a drive of the same capacity with far better read/write speeds and a small box with postage paid so I could return the faulty one to them. This replacement is still running flawlessly nearly seven years later, with SSDlife reporting it'll last until 2033 or so (basically it'll outlive the hardware it's hooked up to).
 
I purchased the disk in December 2017 so not that old. I have contacted the seller (on Amazon) but do not hold out much hope.
I have emailed Seagate support - they promise contact within 24 hours. Will update as and when...
To finalise:
No reply from the seller on Amazon.
Seagate support responded in a timely fashion and stated that it was an OEM disk so they could not help.
Contacted Amazon and had a 'Chat'. Great outcome in that I will return it and get a full refund.
Happy days (and my new 2Tb disk is working well...)
 
Seagate support responded in a timely fashion and stated that it was an OEM disk so they could not help.
I assume you didn't buy the disk as part of some other product (eg. original Humax) but as a replacement disk - so how does it become an OEM disk?
Sounds like Seagate don't want to accept responsibilty. Still, that is completely academic now as Amazon agreed return/refund. 👍
 
It was a 'new' replacement disk so OEM was a surprise. Amazon were very quick to offer the refund so perhaps there is a back story (!?!)
Still who cares (as long as the refund appears)
 
Yep Amazon tend to be excellent with getting it right, or correctly sorting it out when it isn't. 99% of what I order is one day delivery via Prime as promised and they've only messed one of my orders up in a decade.
 
I believe it is not uncommon for sellers on A (and elsewhere) to supply OEM products. I got what turned out to be OEM for my NAS a couple of years ago.
 
@peterworks Hi Peterworks, I've just started having similar problems with my drive and fixdisk is running at the moment and I'm getting the same "Error at LBA 0" with the Running short disk self test process counting down from 62 and stopping around 29. This has been looping for about an hour now. How long did you're go on for

@/df is there a way to tell it to ignore the LBA 0 and carry on checking the rest of the driver? I've run using the -y option so I don't have to stay by the PC all the time.

Also, is there a way to transfer all teh data off the HDD to a USB drive via the humax command line whilst in maintenance mode as booting up is becoming a problem but stable in maintenance mode? (all files decrypted)

Thanks

Rodp

ok presume that's the whole process? Mine fixed about 10 bad sectors which only took a matter of minutes but then got to LBA 0 error and has since then been looping with the same message.

Is the LBA 0 likely to be the last thing it does when running?

Code:
/dev/sda:

This is an advanced-format disk.

     Block 0                    - OK

Running short disk self test
Waiting... [counts down from 62 to 29 then repeats]

Do you think it's still fixing things or do you think it's not really doing anything and I might aswell give up and cancel the operation (ctrl + ] I think) take the HDD out and put it in a USB caddy and see if I can recover the recordings.

Thanks

On another note, when copying off the data. What folder(s) do I need to back up in order to carry over all the custom firmware settings?

Thanks

Rod
 
ok presume that's the whole process?
The log (as posted) shows the start time of fixdisk and the end time of fixdisk so assume that's the whole process.
Looking at the code in post 3 it seems that LBA0 is the first thing it looks at.
 
tell it to ignore the LBA 0
So far as I know, if LBA0 is flakey there is no way to recover from that because LBA0 is where the disk parameters are stored. The only way would be to use manufacturer's tools to map a new sector in its place.
