I have a problem with a newly purchased IOMEGA 250 GB USB drive
(disk is ST325082 -- possible a Seagate).
I hope if someone can tell if this is a defective drive.
The drive works fine with 2.5 - 6 feet USB cable but it had following
error under FreeBSD 4.11:
umass-sim:0:0:0:func_code 0x0901: Invalid target (target needed)
umass-sim:0:0:0:func_code 0x0901: Invalid target (target needed)
umass-sim:0:0:0:func_code 0x0901: Invalid target (target needed)
umass-sim:0:0:0:func_code 0x0901: Invalid target (target needed)
umass-sim:0:0:0:func_code 0x0901: Invalid target (target needed)
da0 at umass-sim0 bus 0 target 1 lun 0
da0: <ST325082 0A 3.AA> Fixed Direct Access SCSI-0 device
da0: 650KB/s transfers
da0: 238475MB (488397168 512 byte sectors: 64H 32S/T 41867C)
When it is used with FreeBSD 6.1, there is no error for short USB cable
(2.5-3 feet).
However, when used with a 6 feet USB cable, system cannot detect this drive.
A couple of other USB drives have been used with these systems and same
cables,
they do not cause any error.
So, what does "func_code 0x0901" mean?
Is this a defective drive?
TIA,
-Jin
