I had a very annoying problem on my Windows 8 system recently.
Once in an hour of active use system would suddenly hang for 10-40 seconds. System event log then would contain following records:
Source: iaStorA EventID: 129 Reset to device, \Device\RaidPort0, was issued.
Source: disk EventID: 153 The IO operation at logical block address 9e1c5b for Disk 1 was retried.
Source: disk EventID: 153 The IO operation at logical block address 7af577b for Disk 1 was retried.
Source: disk EventID: 153 The IO operation at logical block address 7100db for Disk 1 was retried.
Source: disk EventID: 153 The IO operation at logical block address 5cf489b for Disk 1 was retried.
Source: disk EventID: 153 The IO operation at logical block address b6fdc73 for Disk 1 was retried.
and so on...
Disk 1 is Intel 520, SSDSC2CW120A310 and it is my boot drive. Motherboard is based on Intel H61 Express chip set. Lastest Intel storage drivers are used.
