12 Samsung, uh? Here's my story of today. My fried just bought two external
13 USB drives. I wanted to know which brand the HD is, so I checked with
14 hdparm -I, and googled for SAMSUNG HD204UI. I found a story about a bug
15 which makes the drive sometimes forget to write a block when it is
16 attached to a SATA adapter in AHCI mode and when the ATA command
17 "IDENTIFY DEVICE" is sent (like in hdparm -I or when using the
18 smartmontools). There is a firmware patch for this, this is good. But on
19 the annoying side:
21 - You need to make a DOS boot floppy and copy the patch there. I don't
22 know how exactly to do this, and I read about people using Linux who
23 needed over an hour for this or even failed. Can't they just let me
24 download an image I can boot from?
26 - It doesn't work over USB, so I would have to install the drive in a PC.
28 - The new firmware has exactly the same revision number. How stupid is
29 this?? I cannot even find out whether the drives have the problem or
30 not. Except by trying to reproduce the problem.
32 Here's a link to the but I described, but It's German only.
34 I also read some angry comments about Samsung there. Question is, are
35 other manufacturers better? And wasn't Samsung Electronics bought by
36 Seagate anyway?
39 Any idea whether an external USB drive case might count as a SATA
40 controller in AHCI mode? I tried to trigger the bug, but that did not
41 happen, so I guess it's fine, at least when being in the USB case.
43 Another problem is that data access frequently stalls on her PC, like when
44 transferring data or doing a mke2fs. After a while, this message appears
45 in syslog, and the process continues for a while, until it happens again:
47 usb 1-4: reset high speed USB device using ehci_hcd and address 7
49 Same problem with a GRML boot cd and on another USB port. Happens with
50 both drives. But it is fine on my PC.
