I successfully installed an IDE controller (Promise Ultra100TX2) and a
second hard disk (SAMSUNG SP1614N) in my Qube II (running NetBSD
1.6.1). After partitioning and formatting the new drive, I get some
messages in dmesg, regarding the new disk (wd1):

(...)

wd1d: error reading fsbn 0 (wd1 bn 0; cn 0 tn 0 sn 0), retrying
wd1: (aborted command, interface CRC error)
wd1: soft error (corrected)

My impressions are very mixed: Although some errors are shown, I had
no problems transferring a bunch of files (nearly 20 GB) from a
Windows"-powered" PC to the Qube's new disk.


"fdisk wd1" shows the following:

Disk: /dev/rwd1d
NetBSD disklabel disk geometry:
cylinders: 16383 heads: 16 sectors/track: 63 (1008 sectors/cylinder)

BIOS disk geometry:
cylinders: 16383 heads: 16 sectors/track: 63 (1008 sectors/cylinder)

Partition table:

    start 0, size 312581808 (152627 MB), flag 0x0
        beg: cylinder    0, head   0, sector  1
        end: cylinder 1022, head  15, sector 63
1: <UNUSED>
2: <UNUSED>
3: <UNUSED>


Can I just ignore the errors or is there something else I can do to
patch this?
