9	Corrupt written data on FAT32 partitions while downloading files	M. Seidel	somebody	"Hi, I use ECS1.2R and XP on the same machine. Only ECS has access to the www, so files I need for XP are only downloaded with ECS and stored with the installed fat32.ifs directly at the fat32 drives accessible under both systems.

Since longer time and trying different versions of fat32 (including 0.9.13 latest) I wondered that the downloaded files under XP are corrupt. Selfexpanding exe's are stopping with a CRC error or zip files cannot be expand.

Under ECS I use different versions of Seamonkey (latest 1.1.13)

On my formerly PC I had sometimes the same problems.

I have done some experiments:
Downloading the file:
http://startdownload.filefront.com/4286905//6fe471f91cdc109738f8eac44a258057618d7941c6ca8a291bbc33ef2fe926a0a3cdf95c098932f4//
(should be project_51.zip ~130MB)
direct to a fat32 partition

and a 2nd download to a JFS patition

results in the following:

Download to FAT32 drive:
J:\>md5suml project_51.zip
9935917E3288FF884E9B595280BBBCCD project_51.zip
filesize 131127388 Bytes

Archive:  J:/project_51.zip
  inflating: pro51.PK3
  error:  invalid compressed data to inflate
  inflating: readme.txt
ERROR


Download to JFS drive:
F:\>md5suml project_51.zip
6D6A29E52F1055886A4271E53C3FB968 project_51.zip
filesize 131127388 Bytes

Archive:  F:/project_51.zip
  inflating: pro51.PK3
  inflating: readme.txt
OK

So I have written a little file comparison tool.
It compares the good and the wrong file and logs all issues.
See the attached files.
Each line shows the adress, databyte good, databyte bad, total error count and the nummer of continued errors in follow. Please watch the ''follows'' carefully!

If I copy such larger files from HPFS or JFS to a FAT32 drive
with a filecommander, like FC220, no problem occurs.
With my 2Mbit www connection the files are written only slow while downloading them.
May be a small buffer allocation problem in the IFS or cachef32.exe?"	defect	closed	Feedback Pending	Future	IFS		highest	fixed		KO Myung-Hun
