Re: Data lost from zip disks

The files you are trying to open are probably the resource forks which contain no data,
check the size of the files and compare to a comparable "fresh" data file. You may have
the data forks which may have a numerical name only. I have recovered data from a crashed
hard disk using the Norton unerase command, I ended up with the resource forks (named as
the original files) and the data forks with just numerical names, you can re-join the
files using norton but it takes ages. You can again use the unerase command to seach
for file content, so if you search for a file name of a given experiment you should
recover both data and resource forks , you should be able to read the data fork files
in cellquest but you may have to convert them back into cellquest using FACSconvert or
Ray Hick's FACS Assistant. The original file name will be embedded somewhere in the
data fork along witht he Sample ID etc. If the Zip had been used only once the files
should at least be in order.

Moral of the story, dont trust zips get a CD burner.

Good luck

Hi,

we've got a big problem.  We have, in our laboratory, a
FACscan, running CellQuest software and we keep all our data in
zip disks.  Recently, our zip drive got damaged and destroyed the
data from the disks.  We sent the disks for data recovery.  The
company (Ontrack) managed to rescue the files out of the disks
and we can see the items and the names of the files.  However,
when we try to open them in CellQuest, WinMDI or Flow Explorer,
we are told that the files are not in FCS format.  Would someone
know how I could still try to access that data?

Thanks,
