What is ransomware and how do I protect my PC from WannaCry?
I have a 250Gb external LaCie USB2 hard drive, originally FAT32 but re-formatted by me
(using the basic XP(SP2) facility, default allocation unit size (4096??)) to NTFS so as to
avoid the restriction on file sizes (I use it inter alia for Norton Ghost). It seemed to
work OK but a few weeks later I checked my drives to see if they needed defragmenting and
was suprised when the analysis said that the LaCie needed it - surpised because all I had
done was back up files and use Ghost so that everything should have been contiguous.
Windows de-frag showed a very large "free" area shortly after the beginning of the
disc,followed by my files. O&O Defrag gave more details, clusters 800800 to 841559 being
all colour coded light yellow = "reserved for MFT" and "empty" (whatever this all means!);
nearly all earlier & later clusters are all shown as "fragmented". I did another full
re-format but nothing changed.
When I first re-formatted, I did not trouble to delete all my files first since I believed
that to be one of the functions of a re-format. My impression, however, is that the area
now "reserved for MFT" and seemingly inaccessible for normal purposes, is about the size of
the Norton Ghost files on the disc prior to the first re-format.
I have the feeling that I have done something stupid. My only idea to date is to do yet
another re-format - this time for another allocation unit size - to see if that moves the
logjam. But I don't want to destroy my 31Gb of back-ups again unnecessarily!
I would be most grateful for any guidance/suggestions.
Apologies - I made a typographical error in my request for help: the "reserved for MFT" area should read "clusters 800800 to 8414559" (the latter erroneousely quoted as 841559).
Many thanks to DieSse for your contribution - I am on a learning curve here!!
