Memory Card Problem _ File cannot be deleted
  • File can't be deleted - disaster imminent [From Chris Cooper]

On my MalayBook's SanDisk CF card, I have a rogue file that I can't get rid of.
It purports to have the impossible filename " ing.ks. " (with a full stop at
the end); when I click Ctrl-P for its properties I get "Not found" and the same
when I try to delete it or rename it; in the system screen it claims to be 1200
MB in size (not bad for a 256 MB card!)- but in the directory tree it claims to
be about 28 MB.

A soft reset doesn't remove it. The only minor nuisance it creates (apart from
the memory it uses) is that it causes an error message when I backup to my PCD
via PisWin.

Any suggestions?

Yes, your CF card is corrupt. Which, as you may imagine, is a bad thing.
Potentially other files could get damaged, or you might even lose all of them.

So I suggest that you:

1. Backup all the files you can, either onto another CF card, or onto another
computer.

2. Either (a) format the card in your Psion, and then copy your files back,
or (b) download Atelier's Essential Disk Utilities (EDU) from www.
pscience5.net , install CheckDisk to your C disk, and then use it to repair
your CF card.

As to how it could have got corrupted - there are lots of ways. Removing the
card before your Psion had finished writing to it (it's best to switch your
Psion off before removing the CF card). Your Psion crashed in the middle of
writing to the card (unlikely I know!). You let Windows touch your CF card -
although some memory card readers seem to be much worse than others. Or you
have just used your CF card too much, and it is now worn-out in some areas…

Something I forgot to say:

1. Backup all the files you can, either onto another CF card, or onto another computer.
2. Either (a) format the card in your Psion, and then copy your files back, ….

If you choose this option, make sure that you backup EVERYTHING. That includes
the "System" folder, which is usually hidden by your Psion. You can make it
visible by going to Tools/Preferences (or pressing Ctrl-K), and then ticking
both "Show hidden files" and "Show 'System' folder".

These files with dodgy names are caused when the FAT is overwritten by a data
file. You are potentially moments away from losing the whole card's worth of
data.

You almost certainly have a corrupt CF card that you need to format as soon as
you can - if not sooner! Take the card out and recover all your files to a
desktop computer but beware some will not copy as they are corrupt - recover as
many as you can and supplement them with your latest (daily!) backup. Then
format the CF card, copy back all the files you saved and put it back in your
MBook.

I find it's a good idea to regularly take out the CF card, backup all the files
to a desktop computer, format the card and copy the files back because CF cards
get corrupted from time to time.

On the Series 5 low batteries result in corrupt CF cards - I imagine it's the
same with the netBook and variants - keep your battery well charged!
