how to improve recuva's recovery performance

Recuva
1

Hi all,

I am using recuva to recover files from a damaged 500GB WD external disk.

I did a simple scan. I took some hours. then I started recovering

First I selected the documents. took some hours. I recovered them.

now i selected pictures and videos. it takes too much time.

from what i counted, it recovers 10mb per hour.

My question is the following:

- can i do something to my computer to improve the recovering performance?

- should i increase the memory ? or something similar?

- should i use a faster computer?

- does the 10mb per hour sound normal to you (after the scan time)?

thanks a lot for any answer that might help me here

You can try using a faster computer, but it may be a limitation of the damaged disk.

Sounds very low to me though. (the 10mb)

10 mb is close to the maximum of 12 Million BITS per second for a USB1.1 data transfer.

you get 480 Mb = 60 Mega Bytes/Sec max with USB2, see

I am sure WD intend at least USB2 data rate for a 500 GB drive,

but much can go wrong with :-

USB Data cables and connectors ;

USB hubs , especially expander hubs with a broken P.S.U. ;

and your P.C. may also think that the data link and the target are only fit for USB1 operation.

You may have to correct your P.C. to restore USB2 functionality (Google can tell you how).

On top of all that can normally go wrong, you have a drive that is damaged in some undefined fashion.

Perhaps your local Electrical / T.V. / Computer Shack has a guy with a few tools that could fix physical damage and enable USB2
