DriveDX is reporting UDMA CRC error actually. Make sure that you Google what you find before telling the SSD vendor that they owe you a new one (UDMA CRC errors, for example). Now that 14 – 18TB HDDs are affordable, I back up my VI drives to Time Machine along with my iMac Pro. Not inexpensive, takes forever just to build the directory and no guaranty that the recovered data will be useful. The ol' "My cat knocked the TB Cable out…" normally corrupts a drive only … or two when they're in the same TB2 caddy. Reformatting only helps drives that have been corrupted which is not impossible to do. Every one was replaced by an MX500 with much better 3D NAND and 5 year warranties.
OTOH, DriveDX and TechTool Pro found serious SMART errors in every Crucial MX300 I bought before the 3 yr warranty was up. There's a person on MacRumors who'll scream at anyone who'll listen that Apple owes her a new iMac under warranty because of a DriveDX info message-no the SSD is not bad and has years of life before going south. I'm pretty sure this was my cats fault, she walks behind my computer display where the USB hubs are that the drives were attached to, momentarily dismounting the drives by stepping on the hubs, which shortened the life of the two drives that died.ĭriveDX was recommended by a friend of mine who retired a few years ago from working on drives for Apple at their HQ in Cupertino, so it's well worth it to pay attention to what it says about the drive.ĭriveDX is a good utility for diagnosing but it does report non-problems. the other two eventually just stopped working altogether. Mike H is the resident drive expert, but I've had three SSDs do what you describe, one was fixable by reformatting and not dying. the drive is all backed up with a replacement SSD waiting in the wings if needed. So your experience is that reformatting, as suggested by the OS Help, won't help this Michael?. I downloaded DriveX, and it confirms a problem (with just that drive amazingly. Definitely copy everything off of it now!Īlso Everyone should get a copy of DriveDX Those are pretty much similar symptoms to the two SSDs that died on me.
