Bonjour,
Je rencontre des problemes avec une cle memoire USB de la marque PNY de 128Mo.
Sur mon PC (linux 2.4.18-6mdk ) au plug dmesg donne :
usb.c: registered new driver usb-storage
scsi0 : SCSI emulation for USB Mass Storage devices
Vendor: Model: USB DISK 20X Rev: 1.00
Type: Direct-Access ANSI SCSI revision: 02
Attached scsi removable disk sda at scsi0, channel 0, id 0, lun 0
SCSI device sda: 243712 512-byte hdwr sectors (125 MB)
sda: Write Protect is off

USB Mass Storage support registered.
et un fdisk /dev/sda
Disque /dev/sda : 16 têtes, 32 secteurs, 476 cylindres
Unités = cylindres sur 512 * 512 octets
Périphérique Amorce Début Fin Blocs Id Système
/dev/sda1 * 1 476 121840 6 FAT16
Alors que sur mon powerpc (ibm405 -linux 2.4.18 montavista 3.0) le plug donne :
hub.c: USB new device connect on bus1/1, assigned device number 2
scsi1 : SCSI emulation for USB Mass Storage devices
Vendor: Model: USB DISK 20X Rev: 1.00

sda: Write Protect is off

et un fdisk /dev/sda
Disk /dev/sda: 4 heads, 60 sectors, 1015 cylinders
Units = cylinders of 240 * 512 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 1016 121840 6 FAT16
Partition 1 has different physical/logical beginnings (non-Linux?):
phys=(0, 1, 1) logical=(0, 0, 33)
Partition 1 has different physical/logical endings:
phys=(475, 15, 32) logical=(1015, 1, 52)
Partition 1 does not end on cylinder boundary:
phys=(475, 15, 32) should be (475, 3, 60)
Pourquoi cette variation sur fdisk (tetes, secteurs, cylindres) ?
Le message "USB Mass Storage support registered." est t'il fondamentale !!?
Si vous avez des pistes.
Cordialement
Olivier
