 Posted: Mon Mar 08, 2010 8:51 am Post subject: MacBook-pro unknows partition table with usb pendrive |
 |
|
Hi,
I have a kernel-2.6.33 on intel macbook-pro: all works fine now, but i've a problem
when I use hp usb pendrive...
dmesg shows me that hardware is successfully recognized (HP serial code and so on...) but
when it tries to automatically mount:
| Code: | | sdc: unknown partition table |
If I try to mount manually, with or without -t (auto, smbfs, ntfs) he says me: you must specify a partition type (ok it isn't map on sdc1 and so on...)
I've used that pen with other gentoo distribution, so i think all necessary kernel module are included...
Any suggestions are welcome
Thanks
Gianni

what do you get for:
You should be mounting something like /dev/sdc1 if its there. |

sdc1 there isn't because of partition table problem
This is output:
| Code: |
localhost ~ # fdisk /dev/sdc
Command (m for help): p
Disk /dev/sdc: 2021 MB, 2021654016 bytes
255 heads, 63 sectors/track, 245 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x91f72d24
Device Boot Start End Blocks Id System
/dev/sdc1 * 1 246 1974240 b W95 FAT32
Partition 1 has different physical/logical endings:
phys=(244, 254, 63) logical=(245, 200, 18)
|
All is corrent: 2GB and FAT32...

Do you have any data on the disk?
If not, I'd delete sdc1 and re-create it.... don't forget to re-set the partition type to FAT32
You can format it, and it should work in both linux and windows then.

I've more data on the disk...under linux sdc1 isn't created...
now partition type is FAT32, after format is FAT32...where is the difference?
Only thing I can think is that i use it under MacOSx...perhaps that is a problem (macOs create strainge file on usbpen)?!

I've noticed that when you delete and create partitions under windows it creates them with incorrecy boundrys, but creating them under Linux makes them correctly.
You could install dosfstools to get mkfs.vfat to format FAT32?

As i've said, i've used that pen as is, under old gentoo-pc and it was ok (with original win FAT32)!
I can try to use dosfstools

Incredible...
yesterday i've updated iMac24 (9,1) with kernel 2.6.33...
I've tried to insert the same usb pendriver and....incredible!!!
dmesg shows me that sdb1 was created; in fact i've mounted that and
i've seen all content of pendrive. 
Hardaware and kernel option are the same of macbook-pro!
