           Summary: Windows checkdisk fails with N800 having large amount of
                    files on Memory Card
           Product: System software
           Version: 3.2
          Platform: N800
        OS/Version: Windows
            Status: UNCONFIRMED
          Severity: normal
          Priority: Medium
         Component: mmc-and-usb
        AssignedTo: kimmo.hamalainen at nokia.com
        ReportedBy: matti.savolainen at verizon.net
         QAContact: mmc-and-usb-bugs at maemo.org


PROBLEM DESCRIPTION:

Windows XP PC, when connected to N800 using USB cable, is unable to complete
checkdisk (with "Automatically fix file system errors" option turned on) on
memory cards. (in my case 4GB Sandisk Class 2 SDHC card and 8GB Patriot Class 4
SDHC card.) Both of the cards are formatted as FAT32 using 2kB block size. The
problem is reproducible 100% of the time, and affects both internal and
external memory slots. This problem has occurred (at least) with the current
firmware and with earlier firmware. I have tested this in two different N800
devices and the outcome is the same on both. If I check the same SDHC cards
using external SDHC USB card reader connected directly to PC the diskcheck
finishes without problems and does not find any problems on the cards.

EXPECTED OUTCOME:

Windows XP should complete the diskcheck and fix any issues if it finds any.
This works OK if there is NOT large amount of files and folders on the card.
The threshold how many files/folders are needed for this problem to occur is
unknown. (My guess maybe the 32768 is the magic number...)

ACTUAL OUTCOME:

After about 30 seconds since starting the checkdisk, the N800 display lights up
and the PC gives error message saying Windows is unable to complete the disk
check. At the same time the memory card is no longer seen in Windows File
Manager.

STEPS TO REPRODUCE THE PROBLEM:

Copy large amount of files and folders to a N800 memory card and try Windows
diskcheck.

OTHER COMMENTS:

This problem occurs also with latest Chinook firmware on N800 device. The cards
I have tested and have the problem contains over 49.000 files in over 1900
directories.
