Hi,

We know that thin 7mm hard drives are prone to mechanical failures due to their weakness, the scratches possibly being deeper than for other hard drives.

I would like to hear about which ratio of success/failure rate you have experienced (and consequently expect) with those drives when a mechanical repair was required.

I'm especially interested with success rate for Seagate Mobile HDD, in 1TB (e.g. ST1000LM035) and 2TB (e.g. ST2000LM007) capacities.

Don't hesitate to include 7mm drives other brands like Hitachi if this helps having a broader statistical base.
Just tell if your stats include only Seagate drives, or 7mm drives from all brands.

No need for precise statistics but just a rough estimate.

Thanks.

We have excellent results with most Rosewood drives, 95% or better if you exclude badly scratched platters.

Quite often requires a few donors though :-(

i like them too, 90%+ success rate (didn't really count it, but there was only one case where i could not even grab the SA), including the badly scratched ones.

used to change a few heads to get data in st2000lm007.

until we change our technique in head replacement.
works almost all the time with 1 head now.

this drive is really creating new challenge.

Rosewood drives has solved a major challenge of data recovery :idea:
we do have decent success rate on these one.

I have good success rate with Rosewood drives. I think around 90%. according to my experience this drives have tough heads than st4000lm series. St4000lm heads are fragile than this. Most of time i use this Rosewood heads coupple of time after doing head cleaning. but st4000lm has bit of low chances than rosewood.

i noticed, Wd slim has main problem is huge area of bad sectors.
