I have a 20Gb disk (size 2.5) enclosed
within a box, pluggable to the PC
via USB.
The vendor (in Spain) is fujitsu but
I found out that only the disk is
fujitsu. The enclosure is from
OnSpec or from Datafab (I'm not sure).
Well, using a 2.4 kernel (2.4.13 or 2.4.14)
the device is detected: I can format a partition
on it, and use it altmos normally.
Two strange behaviour sympthoms:
1. When formating it (mke2fs), the inode
count, starts very fast (say until 20/40)
and then get very slow.
2. When working with it, the same thing happens.
Usually it works very well (comparable
to a IDE plugged disk), but suddenly
every access to the disk becomes very slow.
And a real problem:
When I halt or reboot linux, with
the disk mounted, the halt processes
stops at "umounting local filesystems"
until (I guess) a timeout is fired.
And then, the following message
scsi: device set offline - not ready or
command retry failed after bus reset
host 0 channel 0 id 0 lun 0
appears, or even this one
I/O error: dev 08:01, sector 8912952
EXT2-fs error (device sd(8,1)): ext2_write_inode:
unable to read inode block -inode: 544101, block=14322
I/O error: dev 08:01, sector 0
I/O error: dev 08:01, sector 32
I/O error: dev 08:01, sector 2888363
I/O error: dev 08:01, sector 0
when I used the disk as the root file system
(booting from a floppy of course).
Any idea? Thanks in advance.
