General questions for terminal Connection

[fabianf]

Hi,

im playing with some HDDs and the terminalconnections.
Just wanna see if i can connect to the terminal by USB to RS232.

Now Ive some questions, becaus i didnt found much on the web.

1. Is it possible to determine the baudrate with a software when I connected the HDD?
2. I often get chars like this one ▒ <- what does it mean?

Code:

▒▒▒՝▒jung
A▒▒5
    ▒▒▒b▒▒▒▒▒▒▒▒j
                 <Spi▒▒▒▒▒▒ 4439
▒Fl▒▒▒TgtCyl:  ` r0▒▒Hd:   0 Znz ▒▒▒Hd:   0 Zn:   1 C▒▒▒▒▒▒▒|
UI%Qe▒|  3 | 1 | ▒▒▒0 | B98B |
| 1S▒▒


3. CRT+Z wont work by any Harddisk. I tried CRT+Y (maybee its changes by german Keyboardlayout) but its the same...


Theres no matter if I connect it a bad HDD or a new one.
Maybee someone can give me some help to understand the terminalconnection better.

Thanks and best regards
Fabian

Some of your errors can be due to missing the ground connection. Other are from the wrong serial port configurations.

Also, are you using a USB -> RS232 Serial adapter, or a USB -> TTL Serial adapter ? What I mean, are you using an adapter with a DB9 connector in one end and an usb connector at the other ? That would be the wrong adapter, you need one with TTL serial voltage levels. From memory, something with a CP2102 or CP2104 in ebay would do the job.

Hi Rogfanther,

thanks for ur reply.

Its a USB to TTL cable. Not USB to RS232 as i wrote. Sorry.

The squares came from the missing ground cable. I forgot to connect it. Now I get a better output by the Terminal from my bad drive I have here.

It seems like both heads are bad?

If I try to give some input with "CRTL+Z" nothing happens... it just posts LED 1102 LED 1102 again and again.

Is there something wrong in my configuration?

best regards

The configuration is right. But Ctrl-Z is for Seagate firmware. I think you have a Samsung one, even if it already says Seagate in the label.

Search the forum for terminal logs of Samsung drives

1. Its a Samsung
2. Bad heads
