Hello,

I had a raid 5 array with 3 drives. (on a USB 2.0 bus :)). After some 
time, on drive failed. After some more time another drive failed and the 
array stopped running.
I know that the usage pattern from the first failure to the second was 
read-only, i.e as a user only reads were performed.
I also know that the cause of the drive's failures was that they just 
dissapeared from the USB bus (probably from a bug in the hard drive's 
enclosure's USB to IDE bridge)

I trashed the array anyway, but since I am new to linux md devices, I 
was wishing that you could help me understand if there was any 
possibility of getting it back up assuming that there was no data 
corruption.
I run kernel 2.6.17 on a debian system and use mdadm for controlling the 
array from user space.
