I have a Samsung 840 Pro SSD installed in the second SATA port in a Dell T3600 workstation. Drive and PC are about four months old, and have worked fine thus far. Windows is not installed on the SSD, which contains non-system files only.

Yesterday morning, I brought the PC out of sleep mode, and invoked a common application, which seemed to hang.

I couldn't break the hang, and so rebooted, which also failed, and finally I shut down the PC, and then rebooted. Windows hung during the boot.

I tried all kinds of stuff to restore Windows, and the only thing that works is unplugging the data cable to the SSD. The SSD also doesn't show up in the BIOS. Windows will not boot with the SSD connected, even though the OS is not installed on the SSD.

Is there anything else I can try, or is it time to get a different SSD?

Try to plug your SSD into a different SATA port on your motherboard or try a different SATA cable. it could simply be a bad connection. I own a pair of 840 pros personally, they don't die easily. unless yours is unfortunately defective, in which case you need to contact the store and request a replacement. from what i can remember, the pro series carry a 5 year warranty.

Hope this helps

I took the SSD out of the PC, and put it into a USB 3.0 docking station, and plugged the station into a couple of PCs that I have.

The USB docking station was recognized.

When I open up Windows Disk Management, it gives a "Data Error (Cyclic Redundancy Check)" for the disk, and the graphical display says that the disk has 960 MB unallocated (it's a 128 GB disk).

So I assume I can't flash the firmware or anything, and it's RMA time.

This SSD is a secondary disk on a PC with SAS drives, and I got it to support very fast small file reads (reading 100K small files).

Does anyone have suggestions on small (64/128 GB) SSD alternatives for this purpose? I've also thought about giving the Velociraptor a try.

Just wanted to say I've had the exact same failure on the 840 Pro three times now. First drive lasted ~3 months, the replacement lasted 1 month, and the second replacement has now just failed on me after ~7 months. What's really frustrating is the hoops you have to go through to get any support from Samsung.

I have a pair of these, and luckily it's always been the data drive that's failed. My OS drive has been solid, knock on wood.

Yikes. I just had a non-pro 840 fail in exactly this manner after 10 months. I'm in the process of getting it RMAd now.

I am the OP on this, and thought I would mention that I replaced the 840 under warranty, and now have it in an external 2.5-inch enclosure for casual use. The warranty return was quick and painless.

I replaced it internally with a Plextor M5Pro, and everything is fine.

Based on this experience, I'm uneasy about using SSDs for primary drives. My vote is still for enterprise hard drives like Seagate Savvio.

I'm a software QA guy, and I continue to wonder just how thoroughly SSD firmware gets tested before shipping.
