My HD (FAT32, 30GB) crashed, and I lost access to many jpg files. The
folders which contained pictures are present, but instead of jpg's
there's only a junk in them, So I think, that directory structure is
overwritten and files are inaccessible. I can locate where the files
can be (from files in previous and next correct directory), but the
extraction is very time-consuming:
- I search cluster by substring 'JFIF'
- I save the cluster and name it *.jpg
- If it's visibly truncated, I read next cluster and append it to
previous.
- The file length is max. 3 clusters ( 3 x 32768 bytes).
There's also hope, that the files are not fragmented. Does exist any
utility which can:
- Extract jpg files by the way described above from given location or
from whole disc?
- Check existing jpg files for correctness, so I need not to view
them?
What are my prospects in using standard chkdsk (I have win2000) or
some other utility? I didn't do any automatic recovery yet.
Thanks.
