SL-C3100 Zaurus HDD Check
« on: February 01, 2020, 05:51:59 pm »
Hello All!

Recently I bought a SL-C3100 from Japan on eBay.
According to the description the internal 4GB drive is faulty and the device is not booting up.
After inserting a new battery and a reset it's back to life now.
It also came witch an additional 4GB Microdrive.
 

To be sure the internal drive is faulty, I entered "D+M" setup and started "HDD Check".
Does anybody know, what the "BANK_X" values mean?
Maybe it is the reliability of the sectors?
BTW: Test of the HDD resulted "OK!"

Rgds,
Stefan

I unmounted my micro-drive, and checked it with a USB-CF adapter.
I used the utility badblocks

Code: [Select]
# badblocks -swv /dev/sda

Unfortunately it's seriously damaged, so I ordered a new micro-drive.
Tested it again, it resulted perfectly working.

This is the equipment I am using. I bought it on Amazon for 15 euro.
The showed microdrive is the damaged one

I wrote my own disk testing program  ;D

Code: [Select]

# make
- generating interface public for disktest ... done
- generating interface public for host_io ... done
- generating interface private for disktest ... done
- generating interface private for host_io ... done
- compiling disktest ... done
- compiling host_io ... done
- linking to disktest

# obj/disktest /dev/hdc
opening /dev/hdc ... done
Checking for bad blocks in read-write mode
From 0 to 1.610.735.615, by 8.192 bytes at time
   [  0   ] BBBBBBBBB..BBBBB.BBBBBBBBBBBB........BBBBBBBBBBBBBBBBBBBBBBBBBBB
   [ 16.6 ] BBBBBBBBBBBBBBBBBBBBBBB.BBBBBBBBBBBBBBBBBB.BBBBBBBBBBBB....BBBBB
   [ 33.3 ] BBBBBBBBBBB...............BBBBBBBBBBB.BBBBBBBBBBBBB.BBBBBBBBBBBB
   [ 49.9 ] BB...BBBBBBBBBBBBBBB.BBBBBBBBBBBBBBB......BBBBBBBBBBBBBBBBBBBBBB
   [ 66.6 ] BBBBBBBBBBBBBBBBB....BBBBBBBBBB.BBBBBBBBBBBBBBB....BBBBBBBBB.BBB
   [ 83.3 ] BBBBBBBBBBBBBBBBBB.BBB.BBBBBB.BBBBB..BB..BB.BBBBB.BBB...........
   [ 99.9 ] .

"." means no problem
"B" means error during I/O

The above disk is a voluntary damaged one used to test the disk-testing program. This application works good with electro-mechanical HDDs but doesn't work with SSDs and flash-devices.

Since it only does 1 pass, it's ~3x times faster than the program"badblocks".

Nice, a faster alternative to badblocks, well done :) I have myself 3 Zauruses with a Microdrive, I'd like to give it a go someday. I guess it's portable, but it will need to be compiled for each OS separately (Sharp/Cacko, pdaXrom, void...), is this correct?

dunno. if you can compile badblocks, then you can compile it; it uses direct IO functions provided by glibc, I haven't tested uclibc and musl.

FWIW, I replaced the microdrives in my Zaurii with CF cards.

Much better and larger storage capacity.
