Re: Oops and BUG's with hfsplus module
hello
i just suffered a severe dataloss with my very similiar
configuration. i'm running ubuntu linux hoary with the standard
kernel 2.6.10-5-powerpc on a powerbook g4. i've hooked up a hfsplus
formatted 160gb lacie d2 firewire harddrive. in ubuntu i was copying
two big (1.5gb) files from internal ext3 to the external drive and in
another shell i wanted to display the contents of the external
harddrive (using ls) when the disaster happened:

CONFIG_LBD is enabled in the kernel configuration but this issue
should be fixed in 2.6.10 right?
interesting are those lines at startup: ("Unexpected PCI resource
length of 1000!" and "sda: asking for cache data failed")

i could provide the whole syslog output if it helps for searching the
error.
my harddrive is now totally screwed up. neither diskwarrior nor
techtool could recover my files. snapfiles filescavenger and prosofts
data rescue only recovered garbage data from my hd. does anybody know
another tool i could try to get my data back?
