Hi,

im trying to recover a slow read WD hd (applyed all the fixes possibles, mods, etc) and tryed using ddrescue (but so slowwwww take ages) and now trying hddsuperclone.

I get a decent speed,

(sorrry for this little bad copy paste)

My question, the skips are big i think, is normal? Phase1 is making, next phases coming can check again the skipped areas?
I run with default setting.

Thx for any tip , greets!

Have you tried to send an email to Scott?

Just a guess, but I'd say you've likely got a bad/weak head and will only get a really partial recovery. Probably will ultimately need a head swap to get a good result.

Hi thx for replys, can be a damaged head, but now im phase 2, hope i can get some files,

The skip size is fine, the head skipping algorithm is adjusting it. From what I can tell from the display output the drive looks like it has 2 heads and one is weak/damaged/bad. After phase2 (about 50% recovery in this case) it will get slow. If the rate drops to zero after phase2 then the head is likely dead, but if it still slowly reads data then the head is weak/damaged. But a weak/damaged head could take a long time (days, weeks, months) to image, and very possibly die during the attempt. How valuable is the data?

Thx for the info. The data is not really valuable, but wanna try to get most data, i think i left the tool try to make some works. We see in phase 3 if i get more info, total are 4 phases and tool stop?

greets

Also, the fact that there are more skips than non-trimmed areas indicates that some of the skips were triggered by a slow read (2 seconds default). That is a likely sign the bad head is reading, but without seeing the log I can't be sure. It does not indicate how slow the bad head will read though, or how many errors it has. You won't know that until it gets past phase2.

There are actually 6 total phases, after phase4 is trimming, then scraping. See the Theory of Operation section in the manual for more information about the different phases.
http://www.sdcomputingservice.com/hddsu ... -Operation

The thing to watch is the remaining time. It is not in any way fully accurate in situations like this, but it can give you an idea of what to expect. Once you get past phase2 it will give a better idea of the time it may take to finish. Usually the remaining time gets a bit more accurate every time it gets to the next phase, but not until the trimming phase will it give the best estimate.

Not sure if i left some days? or with this, nothing i cant do?

thx!

According to this number it would take 6 months to finish. I said it would be slow after phase2. Phase3 will do smaller skips trying to find areas that read faster, but I think that in this case you will not get much more data from it unless you let it run for a few months, assuming the drive would even last that long. I think it is time to stop and see what files you can recover from the partial image. HDDSuperClone has done what it is designed to do, get the most data from the good head(s) first, but now the bad head is reading so slow that it is not worth it to keep going in this case.

Judging by log the OP provided it has 2 heads, which 1 of them is bad/weak.
Unless its small files the OP is looking for, there is no point on trying.

That depends on what files. The disk might read about 100MB per head at the beginning and maybe 65MB at the end (basing this on the skip size, although it is an educated guess, maybe someday I will come up with the reverse formulas to correctly calculate this). That could mean possible recovery of some files such as pictures which are only a few MB in size each and would fit in the good head. But I do admit that recovery chances are not good without professional recovery, would be very lucky to get 30% of files at best, likely much less depending on what software is used for the file recovery and the nature of the files, not to mention disk fragmentation. If the OP has a spare computer and the time (months) then they could let the recovery run and see what happens...

If the OP does wish to keep going with the recovery, in this case I would suggest to change the cluster size to 1 for the rest of the recovery. With read speeds that slow there is no reason to read larger chunks, only to have to trim and scrape them later.

Hi i can try some time more, and i add a command to my line and resume?

hddsuperclone -s /dev/sdb -t /mnt/2/root/intento2/160gb.img -f /mnt/2/root/intento2/lala.log

this line im using right now, i scan the file generated:

file 160gb.img
160gb.img: x86 boot sector

dont see partitions table

greets!

Yes, to continue with a cluster size of 1, add "-c 1" to the command line:

hddsuperclone -s /dev/sdb -t /mnt/2/root/intento2/160gb.img -f /mnt/2/root/intento2/lala.log -c 1

Is this drive connected as USB or directly as SATA/PATA? If connected directly as SATA/PATA then add "--ata" to the command line also. This can help some with error processing time. If USB don't bother with this option, it won't work.

Right, with c1 --ata i see more activity now, the hd is sata directly conencteroot@lubuntu:/home/lubuntu# hddsuperclone -s /dev/sdb -t /mnt/2/root/intento2/160gb.img -f /mnt/2/root/intento2/lala.log -c 1 --ata

But the strange thing i dont see the file image is growing, up..

-rw-r--r-- 1 root root 160041885184 nov 11 03:40 160gb.img

-rw-r--r-- 1 root root 160041885184 nov 11 03:41 160gb.img

Looks the time, and not growing up, insted i see activity in hddsuperclone ..

thx!!

The image shouldn't grow because the tool should already had created the image to the full size with zeros or "bad" or whatever pattern filling the space on the image that could not be read on the source drive.

What are you doing now is attempting to read the data from the source drive to fill (by replacing/over/writting) the "empty" paces on the image file. You are not appending data to the end of it, you are just replacing the zeros or pattern on the middle of it with the correct data that should be there if that data can be retrieved from the source.

It would be interesting to see how this drive would image/clone using an hardware assisted tool !

Technically it uses sparse writes. If you write the last sector to the file Linux will show it as full size. But if you use a command that shows actual disk usage, you will see that it is only taking up the space that has been actually written.

Did you made any progress with this drive ?
