I have actually two problems... and a feeling that they're connected.
First is that Spore trial installer (as i said in other thread, though
i've now given up with it) and a couple of other installers complaing
about non-matching files or something like that and that storage device
I.E. my laptop's hard drive might be damaged and this is what worries me. Also some zip, 7zip, rar
etc. files have corrupted files (appear either as gibberish or the
unzip program thinks they're encrypted [programs used: 7zip, IZarc and
TUGzip, all have same problems]) no matter where i download them or how
many times. Particularly sound and picture files have problems (a
Starcraft map pack had a map that had sound files and program kept that
map as corrupted too). My other computer doesn't get "corrupted" files
when downloaded from same source. No stuff installed from CDs have this
problem or SDcentral or Blizzard's WoW patch DLers but which i find a
bit strange.. It doesn't matter whether the same file is downloaded
with IE or Firefox2/3... it's still corrupted. Renaming when the
browser asks where to put file doesn't help either.
Scandisk and the disk repair tool (what's it in english?) don't find mistakes on harddrive and no viruses on disk neither...
EDIT: Noticed just that certain sized zip, rar, etc. files are "corrupted". I think those that are are over 15MB are easily corrupted... and it doesn't matter what the zip contains. Doing further testing now.
EDIT2: Made a 7z file that contained 4 .exe files, size just over 20MB and unpacked it... no problems... maybe this concerns only downloaded files.
Second problem is that Flash videos on browsers (possibly others too)
tend to freeze but sound still works, even if the file's fully
downloaded. Same with downloaded avi, wmv and some other types.. Also
pics viewed with Firefox (as i don't use IE regularly, only if i have
to test whether something works at all :/) are sometimes...
disarranged, apparently corrupted (as i said, zipped pics tend to be "corrupted"). They work usually after restart though.
I have feeling that you really can't help but i'd like to hear what you thing this problem might be.
Also here are the laptop's specs:
Vista home premium (works fine, if a bit slow shut down/restart,
sometime frozen during those and i had to forcibly close the laptop, if
the HD is damaged this might be the reason...)
ATI radeon (mobility) HD 2600
3 gigs of memory
HD is some 250 gigs large, split in two drives C: and D:.
Web connection is WLAN, the older computer is in same modem but wired connetion, no problems with this.
