>Description:
If I try to mount my Dell Memory Stick 256 MB, I only get /dev/da0 (and not /dev/da0s1) and this appears in dmesg:
umass0: M-SysT5 Dell Memory Key, rev 2.00/2.00, addr 2
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <M-SysT5 Dell Memory Key 5.00> Removable Direct Access SCSI-0 device
da0: 1.000MB/s transfers
da0: Attempt to query device size failed: UNIT ATTENTION, Medium not present
(da0:umass-sim0:0:0:0): READ CAPACITY. CDB: 25 0 0 0 0 0 0 0 0 0
(da0:umass-sim0:0:0:0): CAM Status: SCSI Status Error
(da0:umass-sim0:0:0:0): SCSI Status: Check Condition
(da0:umass-sim0:0:0:0): UNIT ATTENTION asc:3a,0
(da0:umass-sim0:0:0:0): Medium not present
The "Medium not present" error is displayed multiple times until it fails with:
(da0:umass-sim0:0:0:0): Retries Exhausted
Opened disk da0 -> 6
The only way to get /dev/da0s1 is to do the following:
cat /dev/null > /dev/da0s1
Then I get da0s1 and everything works fine, filesystem ist FAT32. But I'd like to be able to mount the stick without this "workaround", it works under Linux-2.6 without any problems at all.
The dmesg during the "cat" is:
(da0:umass-sim0:0:0:0): READ CAPACITY. CDB: 25 0 0 0 0 0 0 0 0 0
(da0:umass-sim0:0:0:0): CAM Status: SCSI Status Error
(da0:umass-sim0:0:0:0): SCSI Status: Check Condition
(da0:umass-sim0:0:0:0): UNIT ATTENTION asc:28,0
(da0:umass-sim0:0:0:0): Not ready to ready change, medium may have changed
(da0:umass-sim0:0:0:0): Retrying Command (per Sense Data)
>How-To-Repeat:
Try to mount a current Dell Memory Stick. There's been a report on questions@ about the same behavior with a Kingston Elite
