Interesting!

Lets see what mine (OCZ Core 32GB) supports:

9 with a raw value of 0, i.e. meaningless
12 with a raw value of 3950, that does not seem to change, again
meaningless
194 Temperature, works
229, 232, 233, 234, 235: Still unknown

A bit disapointing. Not your fault of course.

Hmm. No. Let me check again.

Ok, seems temperature is stuck at cooked 32, which means it
does not actually work. My mistake. Speedfan seems to
display temerature though, and it does raise slightly after
power on and makes sense. No idea what it does or where it gets
the data.

Attribute 12 is now 3956, so it might actually be a device
reset count, not a power cycle count. I had one power-cycle
since yesterday, but a number of reboots.

The other attributes are exactly the same as January, except for
234, which is now raw 571364925191.

Ah, found it. Speedfan swaps HD0 and HD1 in display for some reasonm
probably a bug. This means it does not get temperature from the
SSD either.

Attribute 234 looks like it may be multibyte. For example, some bytes
have increased by 7, another has fallen by 5.

592722311424 = 0x008a0100b900
571364925191 = 0x00850800df07

Attribute 232 looks suspiciously like an ASCII string. Aside from the
leading 08, "3631303138" is an ASCII numeric string, "61018".

9028846498104 = 0x083631303138

I can't see any pattern in the following:

259986015180268 = 0xec74b614d5ec

187423 = 0x00000002dc1f

See pages 25 and 26 of the following document.

Transcend 2.5" Solid State Disk datasheet:
http://www.transcend.co.jp/support/d...et%20v1.08.pdf

The attributes look very similar to yours. However, they are 8 bytes
long, not the usual 6 bytes for HD SMART attributes.

It appears that I may have been correct about the ASCII values. Do
they correspond to the firmware version or date, ie October 18, 2006?

592722311424 = 0x008a0100b900

According to table 4 of the Transcend datasheets, attribute 234 stores
the Average Erase Count and Max Erase Count.

Max Erase Count (Jan / Oct) = 0x00018A / 0x000885
Avg Erase Count (Jan / Oct) = 0x0000b9 / 0x0007DF

Attribute 232 looks suspiciously like an ASCII string. Aside from the

I can't see any pattern in the following:

259986015180268 = 0xec74b614d5ec

The above attribute stores the Halt System ID in byte 0 and the Flash
ID in bytes 1 through 7.

187423 = 0x00000002dc1f--

According to table 5, attribute 235 decodes as follows:

System(Free) Block Count = 0x0200
Good Block Count = 0x--1FDC
