Hi, I think i did everything right but now i cannot initialize the SSD not formatted and I receive a “Unable to write to the last block of the device” error when i try to create a new partition. Screenshots / Pictures : https://www.dropbox.com/sh/12fcg738jzuxr… Any idea here ? Best Alex
Alex - Do you have a universal adapter cable or external case to put the SSD into? See if it can be for formatted externally. If you can, the drives SATA cable is bad.
If it were a normal hard drive I would use the “write zeros”, format option to map out any bad blocks. It might work for the SSD.
This problem has nothing to do with the drive itself but is almost always caused by a bad connector between the board and hard drive. A large proportion ,around 10%, of macbooks that come into my lab for disk replacement have a perfectly good drive but a bad cable the problem seems to be most prevalent in the 2010 macbook pro
Same problem …. bought two 2TB external hard drives from China ….. one seemed to work when I copied data to it. But would not take the 8.57gb I was sending [ MS-DOS [FAT] ] has a limit of 4gb. Then my MAC would simply not recognise the external drive. I tried all the recommended fixes in Disc Utility on both my rather large Macs [in my recording studio]. One is brand new iMac. Neither of the two discs are seen by either Mac … I shall turn the problem over to my ‘man’ on Monday [now Saturday] … but, as with most folk, I won’t give in … wasting hours on this problem. Can’t find the answer!
maybe you guys are trying too hard reading between the lines and the stupid drive has just bunked ittself over time. that has an odd if one was to calculate it, amongst the other possibles here: hardware main/ hardware aux, internal interface/external connector and even direct to usb!. even solid state has failed for no reason and they are supposed to be impervious to mag/shock without moving parts. go figure
I have this problem with a new USB memory stick. It was filled up to 124 GB by my Tesla Sentry mode but now I cannot erase the data to reuse the stick. Every erase option throws up the “Unable to write to the last block of the device” message. Any clues?
