It would appear the SSD drive has failed and will need to be replaced.  If this is still under warranty from Dell, contact Dell support as only Dell support can get it repaired if under warranty.
When trying to start my Dell Inspiron Mini 910 Netbook, after the POST an error msg comes up: A Disk Read Error Occurred Press Ctrl + Alt + Del to Restart.  When you press Ctrl + Alt + Del, it just goes thru the same cycle over and over. After doing some searching on different forums, I found how to run the Dell built in Diagnostics. When the Diagnostic for the SSD was run, it stopped and came up with an error code: 0F00:0244                                         MSG: Disk_0-Block 5799960: Can't Read, Replace Disk or remove Write Protection. As the Diagnostic Ran, It continued coming up with Numerous Additional Blocks that could not be Read.  It seems to me that this STEC 16gb PATA  SSD has quite a few bad blocks on it. Is there anyway to recover these and/or repair these blocks. Or am I looking at having to replace this small SSD? Thanks for anyone who can help. Oldphoneman
