SATA-HDD-2.5-500GB is 500GB SATA HDD drive which works only on 5V and thus can work with A10-OLinuXIno-LIME and A20-OLinuXino and be powered even when power fail and LiPo is attached.
Tested with both boards and our power supply adapters. Also tested and fits in A20-ENC.

What is the exact model and manufacturer?
Dec 20, 2013 @ 18:46:52
Toshiba MQ01ABD050
Dec 20, 2013 @ 20:32:29
WD10JFCX (2.5″, 1TB) and WD7500BFCX (2.5″, 750 GB) have similar power requirements with MQ01ABD…Read/Write – 1.4 Watts but large capacity.

what we noticed is that some HDDs are very sensitive about power supply voltage levels, when LIME is powered by LiPo battery for instance everything is OK as flat 5V is generated, but if the 5V power supply adapter have not 5.0V but drop to 4.7-4.8V when loaded and few SAMSUNG HDDs we tested refuse to work while this Toshiba keep running even at little less than 5V power supply

And what if i power a board (for example A20 MICRO) from a 12V supply, like SY0612E? Does it work with every 2,5″ HDD? 500GB is not enough for me, so i’d like to be sure, that don’t loose my data with a 1TB HDD from another manifacturer.

The A20 board is capable of powering 5V hard-disks! 12V hard-disk requires external power supply! It is not a good idea to provide 12V to a 5V hard-disk. It is ok to use any brands of hard-disks as long as they have SATA connector – just keep in mind – if it is 12V hard-disk you have to power it externally; if it is 5V hard-disk you might plug it to the board, but your power supply should be capable of providing enough power for the disk + the board + any other attached peripherals.

Same problem and question here – unfortunately 5V_SATA_PWR on at the two A20-OlinuXino-MICRO I have on my desk is not populated with a connector and SATA power cable length and connector type of LIPO_BAT made me think the cable needed to go there.
I am powering the board with a SY0612E and the Samsung 1TB drive (5V 0.95A) and the drive does not even make a noise (and of course does not boot up).
Will the board be able to power the drive if I choose the right power supply? Do Olimex sell it?
Do I need to solder the 5V_SATA_PWR connector onto the board or may I abuse LIPO_BAT ?

“Same problem and question here – unfortunately 5V_SATA_PWR on at the two A20-OlinuXino-MICRO I have on my desk is not populated with a connector and SATA power cable length and connector type of LIPO_BAT made me think the cable needed to go there.”
The connector mentioned was moved near the UEXT2 connector for easier connection and access. This is also mentioned in the board revision notes in the user’s manual as:
5V_SATA_PWR connector (altogether with 2x2uF) is changed from WF2S to DW02S and placed near the PWR jack instead of original position.
Speaking of cables you would need to make or purchase a power-adapting cable like this one: https://www.olimex.com/Products/Components/Cables/SATA-CABLE-SET/

0.95A hard disk would work properly only if you use a better power supply. SY0612E actually can power only your hard disk… Look for a power supply able to provide at least 1A at 12V. This means at least 12W power supply adapter.

Yes. I believe the board would be able to power your hard disk if you get a better supply. We don’t have such a supply at the moment. We are usually focused on selling only the tools need for basic board operation.

Do I need to solder the 5V_SATA_PWR connector onto the board or may I abuse LIPO_BAT ?
No need to solder. As I already mentioned above the connector is now located on a new location. Please take a closer look of the top of the board. LIPO_BATTERY is used to power the board and if the battery is capable (say 3000mAh or more) it might also maintain most of the less demanding hard disks operating. Such batteries might provide 1A of current.

To no avail with an 12W (1000mA @12V) power supply.
I ordered a lab power supply now, so I will soon be able to answer the question myself I hope. Heck, but will it work at all with 12V only? For sure?

The driver sounds like it is regularly parking the heads. I’ve tried changing the values of APM and _standby_ using hdparm, but it still doing it.
I’m using ArchLinux.
Any ideas?

How much power can I safely draw from the 5V_SATA_PWR?
