Has anyone had any issues with the sandisk ultra ii in any of your upgraded mac’s?
I put one into my late 2009 mac mini today and it wouldn’t recognise it, so after refitting my old ssd and booted back in to OSX I proceeded to connect the Sandisk to a 3.5/2.5 desktop dock I have and it still wouldn’t show up in Disk Utility?
I understand that this mini is SATA2, and the Ultra is SATA3 but I thought they’re backwards compatible, but the fact it still won’t show up in the external dock confuses me, is there any compatibility issues I have overlooked or have I been unlucky and received a DOA?
Well I have finally managed to initialise it, however it happened because I placed it in the UPPER sata slot of the mini using my already installed 2nd HDD caddy which has a power connector adapter. This 2nd HDD kit used to house my mechanical ‘storage’ hdd, and the LOWER housed the SSD as is normal on the mini, however when I swapped them it appeared and I was able to begin installation?
I wonder if its a power issue, the old SSD that did work in lower slot is a Crucial M4, Rated +5 VDC and 2 AMPS, whereas the SanDisk is 5 & 1.6 AMPS, but to be clear I don’t understand the numbers and/or if its insignificant?
But like I said, I find it pretty bizarre as to why it won’t work in the lower slot, and although there is a threshold limit with SATA2 using a SATA3 drive, I’m getting 202MB’s Write and 252MB’s Read, which is slower than the older M4?
