Subject:CF card format problems
Hi Larry, Rob and list,
During the last few days I have been discussing this problem by phone with
Fred at APH tech support who has been relaying between Larry and me. This
is a rather upsetting, although ultimately not a serious problem. I will
recap for the benefit of the list and to let Larry and Rob know what has
occured since then.
There are 2 BPs involved in this with their respective 2GB CF. I'll call
them BPs 1 and 2. In order to clear the card in BP2 of files, I formatted
it in the BP. I then added a lot of files from an audio CD. Because I
didn't like the way they were arranged on the BP I decided to format again.
I usually just delete but because of the large number and the intention to
remove them all, I reasoned that formatting would be easier, while I was
connected to the computer. There was a firmware update, which I did. I then
disconnected and did the format.
I then reconnected and discoverd that the BP software would not start, and
when started manually indicated that the BP was not connected. I opened
the drive for the card in BP on My Computer, clicked Properties and it
indicated that the 2GB CF was a 1GB with no files and that it had no free
space. I inserted the card from BP1 into BP2 and it worked properly. The
card from BP2 would not work in BP1.
Thinking that the card was corrupted,I obtained a replacement from the
manufacturer(Kingstan)and formatted. Incidentally 2GB cards come
preformatted as FAT32 and after reformatting in the BP, the Properties
incated they were still FAT32. Same problem.
I bought a card reader and formatted again. This solved the problem. The
Properties indicated 2GB with no free space, and after showed all free
space. Both cards worked in BP2. I took one of the cards and formatted in
BP1 and it returned to the unusable state. The cardreader restored it.
I can reach no other conclusion but that Firmware 2.2, which now allows
cards up to 4GB is formatting 2GB cards improperly as FAT32 when they
should be FAT16. I formatted in the card reader as FAT16. I also
formatted a 16MB and a 128MB and these were handled properly. This will
probably only occur with cards around 2GB.
I would appreciate comments on when it is appropriate to format and when it
is not.
Thanks everyone,
Richard
