drivedb.h: Toshiba MG-Series improvement

[S.Haupt]

Dear Smartmontools-Team,

I propose an update to the drivedb.h file in order to correctly support the Toshiba MG-Series harddrives. The current Regexes do not cover all drive models (especially the SAS-Models are not covered). The proposed changes can be found in the attached diff file.

Information on the MG-Series drives are sourced from this Toshiba datasheet:
​https://www.toshiba-storage.com/wp-content/uploads/2018/04

Toshiba Model numbers have the following meaning:

1-4   Series Number
       MGnn: with nn in 04,05,05,06,07,08,09,10
5     Interface
       A: SATA
       S: SAS
6     RPM
       C: 7,200 rpm
7     Height
       A: 26.1 mm
       F: unknown
8-10  Formatted Capacity
       400: 4 TByte
       600: 6 TByte
       800: 8 TByte
       10T: 10 TByte
       12T: 12 TByte
       14T: 14 TByte
       16T: 16 TByte
       20T: 20 TByte
       22T: 22 TByte
11-12 Options
       A: 4K Native (4Kn) AF
       E: 512 B Emulation (512e) AF
       N: 512 B Native (512n) Format
       AY: 4K Native (4Kn) AF and SIE ( Sanitize Instant Erase )
       EY: 512 B Emulation (512e) AF and SIE ( Sanitize Instant Erase )
       NY: 512 B Native (512n) Format and SIE ( Sanitize Instant Erase )

However, I belive this support page describing the model numbers is not 100% correct!

I hope that helps improving smartmontools.

Best regards
Sascha

drivedb.h diff file containing improvements for the Toshiba MG-Series drives

More precise description of my interpretation of:
​https://toshiba.semicon-storage.com/ap-en/storage/support/storage-products-hdd.html

I belive this file is correct until the MG04- or MG05-Series.

However, in later series it seems the interface speed field is also being used for indicating the drive capacity as drives with more than 9 TB came out.

Replying to S.Haupt:

... The current Regexes do not cover all drive models (especially the SAS-Models are not covered).

SAS drives are not included to the database, see the FAQ.

​https://www.toshiba-storage.com/wp-content/uploads/2018/04

This results in File not found.

Toshiba Model numbers have the following meaning: ...

Such a model number scheme does not imply that each combination actually exists.

Please note that the entries for the MG06-MG10 (12-22TB) SATA drives were done based on information directly received from Toshiba Europe.

Please provide a list of identify strings or (if possible) smartctl -x -a ... outputs of actual drives not matched.

drivedb.h for Toshiba MG-Series drives (excluding SAS-Drives)

Dear Christian

Sorry for the incomplete link.
Here is the correct one, I have used:
​https://www.toshiba-storage.com/wp-content/uploads/2018/04/TOSHIBA_16046_DS_MGSeries_server_04-10.pdf

Various other documents with the drives numbers can be found on the Toshiba Storage website:

As I was not aware that SAS drives are not included in the DB, therefore I regarded them in the regexes. I will modify the database file and remove the SAS drives. Therefore just '[AS]' must be replaced by 'S'. I attached an updated diff file.

I have two MG08ADA800E and one MG06ACA800E drives for testing.
However, I also used the drive numbers that were already listed in the comments inside drivedb.h and the numbers from the datasheets.

For testing I used this command:
smartctl -P showall 'TOSHIBA <Drive Number>'

<Drive Number> has been replaced by the drive numbers from the PDF.

I checked the following <Drive Number> from the PDF:

I will add the missing drives soon. Model family names were coordinated with Toshiba Europe and will therefore be left unchanged for now.

Works as exprected.
Thanks for the quick implementation.
