Hi,
When I read from a floppy disk with badsectors and write to a file on the harddisk, I get filesystem corruption. Filesystem on hard- disk is ext3. I'm reading the floppy in raw mode (open("/dev/fd0" etc.). In dmesg I get: floppy0: data CRC error: track 32, head 1, sector 7, size 2 floppy0: data CRC error: track 32, head 1, sector 7, size 2 end_request: I/O error, dev 02:00 (floppy), sector 1176 and suddenly the write fails with 22. The file attributes are suddenly weird: -rwxr-Sr-T 1 root root 602112 Jan 3 00:50 ../test Nothing in the logs. Kernel version is 2.4.18. Harddisk is on IDE: ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx PIIX4: IDE controller on PCI bus 00 dev 21 PIIX4: chipset revision 1 PIIX4: not 100% native mode: will probe irqs later ide0: BM-DMA at 0xd800-0xd807, BIOS settings: hda:DMA, hdb:pio hda: ST320413A, ATA DISK drive ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 No fiddling with hdparm or whatsoever.
