harddisk.mdwn
The harddisk of this server is dying. I have to replace it.
I never bought a harddisk and never replaced one. This may not be a big issue if I figure out the connector details, but I’ll also need to reinstall the whole system. The plan is to do a minimal installation from CD, then run the command to install my packages exactly as they were, and finally extract the entire backup from the backup drive. Will it be so easy? I don’t know. I hope so :-)
This may also be a chance for me to move to Trisquel. If I could somehow prepare everything on the new harddisk and then switch and reboot, it would be awesome. But right now it doesn’t seem to be possible because I need a safe extra machine for that. If a harddisk can be connected via USB, it will help.
Anyway, here are the details.
- Model: ATA WDC WD3200BEKT-60V5T1
- Firmware version: 12.01A21
- Location: Port 1 of SATA host adapter
- Volume: 320 GB
- Partition table: MBR
- Serial number: WD-WXF0AB9Y0119
- Global name: 0x50014ee203c8a87d
- Device: /dev/sda
- Rotation rate: 7200 rpm
- Connector: ATA
- SMART status: The device has bad sectors
Partitions:
- 500 MB ext4 /boot
- 25 GB ext4 /
- 289 GB ext4 /home encrypted
- 6 GB swap encrypted
Changes to make:
- Give more space to root partition or a separate big partition to /var, e.g. the mail server content and tahoe storage should be able to be there
- Consider encrypting root and /var partitions too
- Make a single encrypted volume like on jfm laptop - see again how smcv did it
Information from the manufacturer’s maintenanc guide:
- Height: 9.5 mm
- Width: 70 mm
- Weight: 101 g
- Interface type: SATA
- Transfer rate: 100 MB/sec
- Single track: 3 ms
- Average: 13 ms
- Maximum: 24 ms
- Operating temperature: 5°C to 55°C
Useful info I found:
- Sizes are 1.8, 2.5, 3.5 inch
- Generally, 7 mm, 2.5-inch SATA SSDs will fit even in the 9.5 mm slots and some come with spacers for a tighter fit
- It’s possible to connect the drive externally, so I can more easily prepare the new one and later still keep and use the old one. Examples:
Using the adapter cable, I’ll be able to prepare the new harddrive while still using the current one. Improvements over my current one:
- 500 GB instead of 320 GB
- SATA 3 instead of SATA 2 (not useful right now, but may be in the future)
Since 320 was already enough, basically I’ll get the same speed as before. I don’t expect changes - just get things back to normal operation.
I’m going to use the chance to move to Trisquel, and try it a bit from a Live USB/CD. Some migration to new versions will be required, e.g. gitolite 3:
