How long does a recovery take?
Posted: 02 Nov 2014, 19:39
Hi all, I’m new at this forum, I knew photorec but I’m using it in a professional way just now. First of all, I want to congratulate Christophe for his great program and thank him for support.
Now I’ll explain my situation. I was given an usb external hard disk, size 250 Gb, and it is partitioned as follows:
(E): 25 Gb – NTFS - 100% used
(F): 52 Gb – NTFS - 0% used
(G): 52 Gb – NTFS - 100% used
(H): 52 Gb – NTFS - 19% used
(I): 52 Gb – NTFS - 7% used
... (it will be an extended partition for including the logical ones..)
The (E) 25Gib partition may be damaged because Windows cannot read it without formatting. I’m using photorec for Windows with graphic user interface (qphotorec_win.exe) to recover jpg files only. I randomly selected one of the four 52Gb partitions (but I cannot know which one) and after about 12 hours the recovery was at 90% with 88 recovered images.. Now the process appears freezed if we consider that the first 87% work was faster... is that normal or is anything working bad?
So, as in the subject my main doubt is: how long does this process take on average?
My other questions are:
1. how many passes are there? (pass 0, pass 1... )
2. why the “reading sector” item is always on 0? (e.g. 0/108711855), is that right this way?
3. why for some of these partitions both items of free unallocated space and whole partition are allowed and for some other only the whole partition option is allowed?
4. since photorec does not use drive letters as Windows does, but just numbers, and because of the four partitions have all the same 52 Gb size I cannot spot the correspondence with windows drive letters. Is there a way to figure out this point?
Thanks in advance.
