Success rates?

[cgallery]

What kind of success rate do the people here have recovering data? I have a small PC repair business in Milwaukee, WI and get all kinds of drives with all kinds of problems. Drives that clunk, won't spin, have lots of read errors, or just filesystem corruption. I get desktop and notebook drives, mostly PATA, but some SATA and very few SCSI (mostly U160 and U320). I can recover all the drives with filesystem problems. I can recover about 75% of the drives with mechanical (no spin) problems using various methods I try until either something works or I run out of time. What kind of success rates have others achieved?

Hi,

we have about 75% too including all mechanical problems (head defects, preamp defects and so on).
The problem starts when disk have scratchs.

Hi,
how do you calculate success rates ?

According to me success rate varies every week, depending on the kind of problem and drive that you get.

Suppose in a week you got 20 Seagate Baracuda with Spindle or Head Problems (No Scratches), than success rates might be 100%.

Next week you got 20 Old Drives and you are not able to find the Donor Drives, than it can be 0%. Right ?

I think achieving a success rate of over 60% in Physically Crashed Drives is really a remarkable thing.

well i think the recover rate depends on what kind of failed drives

you prefer to deal with. i think that maybe dealing with the hard cases

no donors, very diffucult mechanical repair in this cases the cost

is very high to the customer and many will drop... of course

it depends how much the data important.......)

for now i dont deal with the very hard cases and maybee its not a bad

idea....

what do you think?
