yes, probably you're right. because i've made several experiments and... when i made 20G sdb1 + 15G sdb2 - everything was right. 50+15 - ok. 100+15 - ok too. 200+15 - got errors.

We have USB subsystem but it's young and has its own issues which are represented by other bugreports and tasks. If this bug isn't a manifestation of BIOS bug feel free to reopen it |

hello! i'm having a problem with usb-hdd "Samsung S2 Portable". first of all, it's partitioned in a such way:
sdb1 is 400G ntfs partition, sdb2 is extended and sdb5 is logical, 15G reiserfs
if i say "ls (hd1)", it displays (hd1,5) as "unknown filesystem".

it works in that configuration because then grub doesn't have to access beyond limit. This problem was already throughly discussed
